Find the slop of the line shown.

Answer: it’s 506

Step-by-step explanation:

The number of cannonballs in the stack exists at 650. Since the stack is in the formation of the square pyramid the total number of balls can be acquired by utilizing the formula for discovering the total number of spheres in the square pyramid.

Find the number of cannonballs in the stack:

Given that the pyramid stands a square pyramid and the numeral of balls that form the side of the square exists 12.

By utilizing the formula of a square pyramid,

n(n+1)(2n+1)/6

12(12+1)(2(12)+1)/6

12(13)(25)/6

2*13*25

=650

Therefore the number of cannonballs in the stack exists at 650.

Answer:

x=0.27

Step-by-step explanation:

The given expression is

[tex]e^{\frac{1}{4}x}=|4x|[/tex]

To solve this equation, we graph the functions:

[tex]f(x)=e^{\frac{1}{4}x}[/tex]

and

[tex]g(x)=|4x|[/tex]

From the graph, the two curves intersects at x=-0.24 and x=0.27.

But the domain of the logarithmic function is x>0

Therefore x=0.27

Answer:

(a + c, b)

Step-by-step explanation:

First the easy part... the Y-value.

There's an horizontal line where the P is... that line has a point identified (a,b).  So, the Y-value of P is b.

Now the X-value.  

You see that P is a bit right to c, so it's something more than c, but how much?  If you look, P is as right to C as a is to the origin.  Since we know it's a parallelogram, the line that goes from origin to (a,b) is parallel to the one going from C to P.

So the X-value of point P is: c + a

Step-by-step explanation:

How many unique combinations are possible in total?

This question takes 5 objects randomly out of a bag of 50 objects. The order in which these objects come out doesn't matter. Therefore, the number of unique choices possible will the sames as the combination

[tex]\displaystyle \left(50\atop 5\right) = 2,118,760[/tex].

How many out of that 2,118,760 combinations will satisfy the request?

Number of ways to choose 2 red candies out a batch of 28:

[tex]\displaystyle \left( 28\atop 2\right) = 378[/tex].

Number of ways to choose 3 green candies out of a batch of 8:

[tex]\displaystyle \left(8\atop 3\right)=56[/tex].

However, choosing two red candies out of a batch of 28 red candies does not influence the number of ways of choosing three green candies out of a batch of 8 green candies. The number of ways of choosing 2 red candies and 3 green candies will be the product of the two numbers of ways of choosing

[tex]\displaystyle \left( 28\atop 2\right) \cdot \left(8\atop 3\right) = 378\times 56 = 21,168[/tex].

The probability that the 5 candies chosen out of the 50 contain 2 red and 3 green will be:

Where:

[tex](x_ {1}, y_{1}) and (x_ {2}, y_{2})[/tex] are two points through which the line passes.

[tex](x_ {1}, y_{1}) = (0,6)\\(x_ {2}, y_{2}) = (2,9)[/tex]

Substituting in the equation:[tex]m = \frac {9-6} {2-0} = \frac {3} {2}[/tex]

ANswer:

Question 3:

For this case we have that by definition, the slope of a line is given by the following formula:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]

Where:

[tex](x_ {1}, y_{1}) and (x_ {2}, y_{2})[/tex]are two points through which the line passes.

We have as data:

[tex]m = \frac {7} {8}\\(x_ {1}, y_{1}) = (- 2,1)[/tex]

Substituting in the formula:

[tex]\frac {7} {8} = \frac {y_ {2} -1} {x_ {2} - (- 2)}\\\frac {7} {8} = \frac {y_ {2} -1} {x_ {2} +2}[/tex]

Point A: (6,8)

[tex]\frac {7} {8} = \frac {8-1} {6 + 2}\\\frac {7} {8} = \frac {7} {8}[/tex]

Equality is met.

Answer:

We have as data:

[tex]m = \frac {1} {6}\\(x_ {1}, y_{1}) = (0, -3)[/tex]

Substituting in the formula:

[tex]\frac {1} {6} = \frac {y_ {2} - (- 3)} {x_ {2} -0}\\\frac {1} {6} = \frac {y_ {2} +3} {x_ {2} -0}[/tex]

We substitute each of the points and see if the equality is met:

Point A: (-3,0)

[tex]\frac {1} {6} = \frac {0 + 3} {- 3-0}\\\frac {1} {6} = \frac {3} {- 3}[/tex]

It is not fulfilled!

Point B: (6, -2)

[tex]\frac {1} {6} = \frac {-2 + 3} {6-0}\\\frac {1} {6} = \frac {1} {6}[/tex]

Equality is met!

ANswer:

Option B

Answer: Option A

A. 0.98

Step-by-step explanation:

Plan A consists of:

Plan A: treat with antibiotics 1. If not effective, treat with antibiotics 2

Antibiotic 1 has a probability P (1) of 0.8 to be effective

Antibiotic 2 has a probability P (2) of 0.9 to be effective.

For a patient to be treated successfully with plan A it can happen that:

The antibiotic 1 works, or that the antibiotic 1 does not work but the 2 antibiotic if it works.

So the probability that plan A works is:

[tex]P = P (1) + P (not\ 1) P (2)\\\\P = 0.8 + (1-0.8) (0.9)\\\\P = 0.8 + 0.2 * 0.9\\\\P = 0.98[/tex]

The probability of a patient being successfully treated under plan A, which involves treatment with antibiotic 1 and then antibiotic 2 if the first fails, is 0.98, or 98%.

The probability that a patient treated under plan A will be successfully treated is calculated by summing the probabilities of success in each step. Initially, the patient is treated with antibiotic 1 which has an 80% success rate. If this fails (which will happen 20% of the time), then the patient is treated with antibiotic 2 which has a 90% success rate. This 90% will only occur, though, for the remaining 20% of patients who failed the initial treatment. Thus, we calculate this like so: Probability(successful treatment under plan A) = (successful treatment with antibiotic 1) + ((failed treatment with antibiotic 1)*(successful treatment with antibiotic 2)) = 0.8 + (0.2*0.9) = 0.98. Therefore, the probability of successful treatment under plan A equals 98% or 0.98, which corresponds to Choice A.

Answer:

Step-by-step explanation:

Function g(x) = x - 2 is in the denominator.  We cannot divide by zero, so the domain of (f/g)(x) is x ≠ 2.

To find the domain of f(x)/g(x), consider where g(x) is not zero as division by zero is undefined. The domain is all real numbers except x = 2.

The domain of f(x)/g(x) is determined by the values of x that make the expression defined while avoiding division by zero. To find the domain, we need to consider where g(x) is not equal to zero, as division by zero is undefined.

Given: f(x) = (x+1)⁻¹ and g(x) = x-2. As g(x) is not zero at x = 2, the domain of f(x)/g(x) is all real numbers except x = 2.

Answer:

Given,

f(x)=x^2+6

g(x)=2x-1

Now,

g[f(x)]=g(x^2+6) since f(x)=x^2+6

=2(x^2+6)-1 since x > x^2+6

=2x^2+12-1

=2x^2+11

In order to find g[f(x)], we substitute the equation for f(x) into the equation for g(x). We replace every 'x' in g(x) with f(x) to get g(f(x)) = 2*(x^2 + 6) - 1. After simplification, we get g[f(x)] = 2x^2 + 11.

In the world of mathematics, g[f(x)] represents the composition of two functions, f(x) and g(x). In this case, f(x) = x^2 + 6, and g(x) = 2x - 1. The composition of these two functions, expressed as g[f(x)], involves plugging the equation for f(x) into the equation for g(x).

Here's how we do it:

First, we take the f(x) = x^2 + 6. Then we put this into g(x), replacing every 'x' in g(x) with our function f(x). So, g(f(x)) = 2*(x^2 + 6) - 1. Simplifying, we find:

g(f(x)) = 2x^2 + 12 - 1 = 2x^2 + 11.

Therefore, the content loaded f(x) = x^2 + 6, g(x) = 2x - 1, g[f(x)] = 2x^2 + 11.

Answer:

B)5/3

Step-by-step explanation:

"3x + 5y = 15."

Rewrite in slope-intercept form.

The slope-intercept form is  

y=mx+b

where  m is the slope and  b  is the y-intercept.

y=mx+b

Subtract  3x  from both sides of the equation.

5y=15−3x

Divide each term by  "5"  and simplify.

5y/5=15/5−3x/5

"5" and "5" cancel each other out

Divide  15  by  5

y=3-3x/5

Reorder  3  and  −3x/5

y=-3x/5+3

Rewrite in slope-intercept form.

y=−3/5x+3

Slope:-3/5

The equation of a perpendicular line to  y=−3x/5+3  must have a slope that is the negative reciprocal of the original slope.

mperpendicular=−1/(−3/5)

Simplify the result.

mperpendicular=5/3

hope this helps!

To find the slope of a line perpendicular to the line 3x + 5y = 15, you first find the slope of the given line, which is -3/5 after rearranging to slope-intercept form. The slope of the perpendicular line is then the negative reciprocal of -3/5, which is 5/3.

To find the slope of a line perpendicular to the given line 3x + 5y = 15, we first need to find the slope of this given line. For this we rearrange the equation into y=mx+b (slope-intercept) form. The given equation can be rewritten as y = -3/5x + 3. Therefore, the slope of this line (m) is -3/5.

The slope of a line perpendicular to the original line is the negative reciprocal of the slope of the original line. Therefore the slope of a line perpendicular to 3x + 5y = 15 is the negative reciprocal of -3/5, which is 5/3. So, the correct answer is B. 5/3.
