Brian has reduced his cholesterol level by 20% after his last check up. If his original level was 240, what is his cholesterol level now?
Answers
Answer:
[tex]New\ level\ of\ cholesterol = 192[/tex]
Step-by-step explanation:
Given:
Reduced level of cholesterol = 20%
Original level of cholesterol = 240
We need to find cholesterol level now
Solution:
First we find reduced level of cholesterol using percentage formula.
[tex]Percentage = \frac{Value}{Toatl\ value}\times 100[/tex]
Substitute all known value in above formula.
[tex]20 = \frac{Value}{240}\times 100[/tex]
[tex]Value = \frac{20\times 240}{100}[/tex]
[tex]Value = \frac{4800}{100}[/tex]
[tex]value = 48[/tex]
So reduced level of cholesterol = 48
But we need to find cholesterol level now, so we subtract reduced level from original level of cholesterol.
[tex]New\ level = original\ level - reduced\ level[/tex]
[tex]New\ level = 240 -48[/tex]
[tex]New\ level = 192[/tex]
Therefore, Cholesterol level at present = 192

What is the equation of the inverse of the function?
f(x)=3x8+1
options:
f−1(x)=83x−13
f−1(x)=83x−83
f−1(x)=83x−1
f−1(x)=38x−1
Answers
Final answer:
The inverse of the function f(x) = 3x^8 + 1 is found by reversing the operations: subtract 1, divide by 3, and take the eighth root. The correct equation for the inverse is f⁻¹(x) = ⁸√((x - 1) / 3), which simplifies to f⁻¹(x) = ((x - 1) / 3)^(1/8). The options provided do not match this result.
Explanation:
The question asks for the equation of the inverse of the given function f(x) = 3x^8 + 1. To find the inverse function, f⁻¹(x), we must reverse the operations of the original function on x. First, you would subtract 1 from both sides to undo the addition, and then divide by 3 to undo the multiplication, followed by taking the eighth root to reverse the exponentiation. The correct inverse function will therefore reverse all these operations in that order.
Here's the step-by-step solution:
Start with y = 3x^8 + 1
Subtract 1 from both sides: y - 1 = 3x^8
Divide both sides by 3: (y - 1) / 3 = x^8
Take the eighth root of both sides: x = ⁸√((y - 1) / 3)
Therefore, the inverse function is f⁻¹(x) = ⁸√((x - 1) / 3), which simplifies to f⁻¹(x) = ((x - 1) / 3)^(1/8). However, none of the options provided fully match this result, implying there might be a typo or mistake in the question or options provided.

What does the y-intercept represent in this problem situation? Explain your answer.
Answers
Answer:
The y-intercept represent Height
Step-by-step explanation:
In a graph the independent variable is plotted on the X axis and attain only certain discrete values. The Dependent variable is plotted against the Y axis and may be discrete or continuous.
Here in the given question
Days: 2,5,8,12,18,22,25,30,32,35
Height: 3,4,6,9,13,15,16,20,21,24
The height is a dependant variable because we are trying to determine a relationship between the Days and the height. In particular, we are trying to see how the height depends upon what day it is or what is the height of the pant on the particular day.
The day can be only discrete values where height can be both discrete and continuous.
So height can be represented along Y axis
Answer:
The height at the beginning of the experiment.Step-by-step explanation:
The relation that the problem shows is between Days (x) and Height (y).
Remember that a y-incercept is a point with the form (0, k), where k is a real number.
In this case, the y-intercept represents the height of a tomato plant at day zero. In other words, it represents the initial condition, the height at the beginning of the experiment.

A plant is already 45 centimeters tall, and it will grow one centimeter every month.
Let H be the plant's height (in centimeters) after M months.
Write an equation relating H to M. Then use this equation to find the plant's height after 33 months.
please give the equation and the pants height after 33 months thank you
Answers
78 is the total
78=45+33(1)
The equation that represents the plant's height H after M months is H = 45 + M. Substituting 33 for M gives us a plant height of 78 centimeters after 33 months.
Explanation:To find the equation that relates H to M, we start with the initial height of the plant, which is 45 centimeters. We are given that the plant grows by one centimeter each month, this information provides us with a constant rate of growth.
The equation can therefore be expressed as:
H = 45 + M
Using this equation, we can calculate the height of the plant after 33 months. To do this, we simply substitute 33 for M in our equation:
H = 45 + 33
H = 78
Therefore, the plant's height after 33 months will be 78 centimeters.

The steps to find the slope of the function [tex]f(x)[/tex] shown in the table attached, are the following:
- Choose two points, from the table:
[tex](0,3)[/tex] and [tex](4,-1)[/tex]
- You can say that:
[tex]y_2=-1\\y_1=3\\\\x_2=4\\x_1=0[/tex]
- Substitute values into the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]:
[tex]m=\frac{-1-3}{4-0}[/tex]
- Finally, evaluating, you get:
[tex]m=\frac{-4}{4}\\\\m=-1[/tex]
Therefore:
1) The slope of the function [tex]g(x)[/tex] is [tex]0[/tex] and the slope of the function [tex]f(x)[/tex] is [tex]-1[/tex].
2) The negative slope of the function [tex]f(x)[/tex] shows that it is the line is increasing and the slope [tex]0[/tex] of the function [tex]g(x)[/tex] shows that the line will always have the same y-coordinate.

For hockey practice, Rosa has to skate around a face off circle five times. The face off circle has a diameter of 9.0m. About how far does Rosa have to skate?
Answers
Answer:
[tex]Distance\ cover\ by\ Rosa = 141.3\ m[/tex]
Step-by-step explanation:
Given:
Rosa has to skate around a face off circle five times.
[tex]Distance = 5\times circumfrance\ of\ circle[/tex]
Diameter of a circle = 9.0 m
Radius of a circle = [tex]\frac{d}{2} =\frac{9}{2}=4.5\ m[/tex]
Solution:
We know that the circumference of a circle.
[tex]C = 2\pi r[/tex]
Where;
r = Radius of a circle
Substitute [tex]\pi =3.14\ and\ r = 4.5[/tex] in above equation.
[tex]C = 2\times 3.14\times 4.5[/tex]
[tex]C = 28.26\ m[/tex]
So, the circumference of the circle is 28.26 m.
Rosa has to skate around a face off circle five times, so Rosa cover 28.26 m 5 times.
[tex]Distance\ cover\ by\ Rosa = 5\times 28.26[/tex]
[tex]Distance\ cover\ by\ Rosa = 141.3\ m[/tex]
Therefore, the distance cover by Rosa to skate 141.3 m.
Rosa has to skate approximately 141.35 meters to go around the face off circle with a diameter of 9.0m five times.
To calculate how far Rosa has to skate, we need to determine the circumference of the face off circle, which can be calculated using the formula C = pi × d, where C is the circumference and d is the diameter of the circle. Since Rosa skates around the circle five times, we will multiply the circumference by five.
Given that the diameter (d) of the face off circle is 9.0 meters, the circumference is:
C = pi × d = pi × 9.0mC = 28.27m (approximately, using pi = 3.14)Now, we calculate the total distance Rosa skates by going around the circle five times.
Total distance = Circumference × Number of laps
Total distance = 28.27m × 5 = 141.35m
Therefore, Rosa has to skate approximately 141.35 meters around the face off circle.

The formula to solve a quadratic equation of the form

is equal to
[tex]x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}[/tex]
in this problem we have
[tex]6x^{2} +7x+k=0[/tex]
so
[tex]a=6\\b=7\\c=k[/tex]
substitute in the formula
[tex]x=\frac{-7\pm\sqrt{7^{2}-4(6)(k)}} {2(6)}[/tex]
[tex]x=\frac{-7\pm\sqrt{49-24k}} {12}[/tex]
so
[tex]x_1=\frac{-7+\sqrt{49-24k}} {12}[/tex]
[tex]x_2=\frac{-7-\sqrt{49-24k}} {12}[/tex]
Remember that
[tex]2x_1+3x_2=-4[/tex]
substitute
[tex]2(\frac{-7+\sqrt{49-24k}} {12})+3(\frac{-7-\sqrt{49-24k}} {12})=-4[/tex]
[tex](\frac{-14+2\sqrt{49-24k}} {12})+(\frac{-21-3\sqrt{49-24k}} {12})=-4[/tex]
Multiply by 12 both sides
[tex](-14+2\sqrt{49-24k})+(-21-3\sqrt{49-24k})=-48[/tex]
[tex]-35-\sqrt{49-24k}=-48[/tex]
[tex]\sqrt{49-24k}=48-35[/tex]
[tex]\sqrt{49-24k}=13[/tex]
squared both sides
[tex]49-24k=169\\24k=49-169\\24k=-120\\k=-5[/tex]
therefore
The equation is
[tex]6x^{2} +7x-5=0[/tex]
The roots are
[tex]x=\frac{-7\pm\sqrt{49-24(-5)}} {12}[/tex]
[tex]x=\frac{-7\pm\sqrt{169}} {12}[/tex]
[tex]x=\frac{-7\pm13} {12}[/tex]
[tex]x_1=\frac{-7+13} {12}=\frac{1} {2}[/tex]
[tex]x_2=\frac{-7-13} {12}=-\frac{5} {3}[/tex]
Final answer:
To find the constant k, use Vieta's formulas to express x_1 and x_2 in terms of the equation coefficients, then solve the given equation 2x_1+3x_2=−4 to find individual values for x_1 and x_2, and use these values to determine k through the product of the roots.
Explanation:
The student needs to find the constant k in the equation 6x^2+7x+k=0, given that x_1 and x_2 are roots of this equation, and that 2x_1+3x_2=−4. According to Vieta's formulas, which relate the roots of a polynomial to its coefficients, the sum of the roots is −(b/a) and the product of the roots is (c/a). Since the coefficient of x^2 (a) is 6 and the coefficient of x (b) is 7, we can state that x_1 + x_2= −7/6 and x_1x_2 = k/6.
Using the second given condition, 2x_1+3x_2=−4, we can substitute x_2 from the first Vieta's formula: x_2= −(7/6)−x_1, and plug this into the second condition to get 2x_1+3(−(7/6)−x_1)=−4. Simplifying, we find a value for x_1. We then substitute this x1 back into the expression for x_2 to find its value. With both x_1 and x_2 found, we use the product of the roots to find k: k = 6(x_1x_2).

Suppose that 70,000 is invested at 6% interest. Find the amount of money in the account after 8 years if the interest is compounded annually
Answers
The amount of money in account after 8 years is $ 111569.36
Solution:
Given that, Suppose that 70,000 is invested at 6% interest
We have to find the amount of money in the account after 8 years if the interest is compounded annually
Formula for Amount compounded annually is as follows:
[tex]\mathrm{A}=P\left(1+\frac{r}{100}\right)^{n}[/tex]
Where,
"A" is the total amount after "n" years
"P" is the principal
"r" is the rate of interest
"n" is the number of years
Here in this sum,
P = 70000
r = 6 %
n = 8 years
Substituting the values in formula,
[tex]A = 70000(1+\frac{6}{100})^8\\\\A = 70000(1+0.06)^8\\\\A =70000 \times 1.06^8\\\\A = 70000 \times 1.59384\\\\A = 111569.36[/tex]
Therefore, the amount of money in account after 8 years is $ 111569.36
When $70,000 is invested at an annual interest rate of 6%, compounded annually for 8 years, the amount in the account will grow to approximately $104,613.78.
Explanation:This question asks you to calculate future investment value when $70,000 is invested at 6% interest, compounded annually for 8 years. The formula we use for compound interest is A = P(1 + r/n)^(nt), where 'A' is the amount of money accumulated after n years, 'P' is the principal amount (the initial amount of money), 'r' is the annual interest rate (in decimal), 'n' is the number of times that interest is compounded per year, and 't' is the time the money is invested for in years.
Since it's compounded annually, n equals to 1. So the formula now becomes A = P(1 + r)^(t). Plug in the given amounts into the formula: A = 70000(1 + 0.06)^(8). Solving this equation, we find that the amount of money in the account after 8 years will be approximately $104,613.78.

Answers
Answer:
Step-by-step explanation:
Final answer:
The shortest distance from the park to the library, forming a right-angled triangle with sides of 6 miles and 11 miles, can be found using the Pythagorean theorem, and it is approximately 12.5 miles when rounded to the nearest half mile.
Explanation:
The question involves finding the shortest distance from the park to the library. This is a basic problem of geometry that can be solved using the Pythagorean theorem. Since the park is 6 miles due west of your house and the library is 11 miles north, we can form a right-angled triangle with one side as 6 miles and the other side as 11 miles.
We find the shortest distance by calculating the hypotenuse of the right-angled triangle:
Represent the distances as sides of a triangle: one leg is 6 miles (west) and the other is 11 miles (north).
Apply the Pythagorean theorem: hypotenuse2 = 62 + 112
Calculate the hypotenuse: hypotenuse = √(62 + 112) = √(36 + 121) = √157
Find the nearest half mile: √157 is approximately 12.53. So rounded to the nearest half mile, the distance is 12.5 miles.
Therefore, the shortest distance from the park to the library is about 12.5 miles.

In a certain town there were 332 robberies last year. This year the number of robberies has gone down 14%. How many robberies were there this year, to the nearest whole number?
Answers
To find the number of robberies this year, we need to calculate 14% of last year's total and subtract it from that total. This results in an estimated 286 robberies this year.
Explanation:The question asks for the number of robberies this year given a 14% decrease from the prior year's total of 332 robberies. To calculate this, you would multiply last year's number of robberies by 14% (or 0.14) to find the decrease in robberies. Then, subtract this decrease from the original number of robberies.
First, calculate the decrease: 332 * 0.14 = 46.48. This rounds down to 46 robberies, as it would be unlikely to have a fraction of a robbery.
Next, subtract this from the original amount: 332 - 46 = 286. There were approximately 286 robberies this year, rounded to the nearest whole number, assuming a 14% decrease from 332.
