What are the domain restrictions of the expression g^2

Answer:

b = -5

Step-by-step explanation:

So we know

3a = -9

Divide 3 on both sides

a = -3

Plug a in to the other equation

-3b = 15

divide -3 on both sides

b = -5

Answer: C

Step-by-step explanation:

Degree of 5 means there are 5 roots.

If 3 roots are real, then there are 2 remaining - which must be imaginary.

Answer:

The answer is C.

Step-by-step explanation:

Recall that as consequence of the Fundamental Theorem of Algebra, a polynomial of n-th degree has n complex roots (some roots, or all of them, can be real).

Now, as we have a polynomial of degree 5, it has 5 roots. From the statement we know that its graph has three intercepts with the X-axis, which is equivalent to the existence, at least, of three real roots. Moreover, we know that the multiplicity of each root is one. Then, we have exactly three real roots.

The above deduction means that there are other two roots, and those must be complex.

To determine the number of different Hyundais available in black or blue, you multiply the number of dealerships (6) by the number of Hyundai models (8) and the number of relevant colors (2), resulting in 96 different cars.

The question asks how many different cars you can buy if you want a black or blue Hyundai, given certain constraints. There are six dealerships, two car companies, eight models, and four colors available. To answer this, we calculate the total combinations possible with the given choices: dealerships (6), car companies (2), models (8), and colors (4). Since we are only interested in Hyundai cars in black or blue, we eliminate other colors and car companies from the choice set. The calculation is as follows:

Number of dealerships: 6
Car companies: 1 (only Hyundai)
Car models: 8
Car colors: 2 (black or blue)

To find the total number of possible combinations, we multiply the number of each category's choices together:

6 (dealerships)
* 1 (Hyundai)
* 8 (models)
* 2 (colors)
= 96 different cars

Given equation is:

[tex]T=36x+60[/tex]

Where T is the total cost; $36 is the entry fee per person and $60 is the one time bus parking fee.

As given, the bus holds up to 40 people, so let the total number of people be represented by 'x'

The bus holds up to 40 people so 'x' is either less than 40 or equal to 40.

Or this can be written as : [tex]x\leq 40[/tex]

Hence, the domain will lie between 0 and 40.

So option C : 0≤ x≤ 40 is the answer.

Probability of rolling a 5: 1/6

Probability of rolling a number greater than 3: 3/6

The probability of rolling a 5 or a number greater than 3 on a six-sided die is calculated by summing the individual probabilities of rolling a 4, 5, or 6, which are each 1/6. Therefore, the total probability is 3/6 or 1/2, equating to a 50% chance.

To solve this, we need to identify the favorable outcomes and divide them by the total number of possible outcomes. A six-sided die has six possible outcomes: {1, 2, 3, 4, 5, 6}. The event of rolling a 5 or a number greater than 3 includes the outcomes {4, 5, 6}. Hence, there are three favorable outcomes for the desired event (rolling a 4, 5, or 6).

The probability of any single outcome is 1/6, as there are six sides to the die. Therefore, the probability of rolling a 5 or a number greater than 3 is calculated by adding the probabilities of rolling each of these numbers:

Adding these probabilities gives us 3/6 or 1/2, making the probability of rolling a 5 or a number greater than 3 being 50%.

Answer:

The correct explaination is Point G can be the centroid because 12:6 equals 2:1

Step-by-step explanation:

Given in  triangle ABC, the segments drawn from vertices intersect at point G.

Segment FG measures 6 cm and and segment FC measures 18 cm.

FG = 6 cm & FC = 18 cm

and also FC = FG + GC

               18 = 6 + GC   ⇒ GC = 12

Note: The centroid divides each median in a ratio of 2:1

& 12:6 give rise to 2:1

Hence, the correct explaination for this is Point G can be the centroid because 12:6 equals 2:1

Answer:

3400 grams.

Step-by-step explanation:

We have been that Noah made 12 kg of trail mix for his family's hiking trip. His family ate 8600 g of the trail mix on the hiking trip.

Let us convert 12 kg into grams.

1 kg= 1000 grams  

12 kg = 12*1000 grams =12000 grams.

Let u subtract 8600 from 12000 grams to find the amount of trail mix left.

[tex]\text{The amount of trail mix left}=12000-8600[/tex]

[tex]\text{The amount of trail mix left}=3400[/tex]

Therefore, Noah had 3400 grams left of trail mix.

The correct answer is Option 4, the fourth graph

Step-by-step explanation:

We will go through why the other graphs are not the correct answer and then explain why the fourth is indeed the correct answer.

Option 1 is wrong because it has the general shape of the graph of an even valued function. These functions are either concave up or concave down.

Option 2 is wrong because it has the general shape of the cubic function. These functions are defined for both negative and positive values of x.

Option 3 is wrong because it is not defined for negative values of x. It has the general shape of the square root function.

Option 4 is correct because it has the general shape of the function [tex]f(x)=\sqrt[3]{x}[/tex]. Functions of this kind are defined for both negative and positive values of x.

Answer:

23 packages

Step-by-step explanation:

We are told that the school cafeteria needs to buy 200 new forks. Each package contains 9 forks.

To find the number of packages that school cafeteria should buy we will divide total number of needed forks by number of forks in each pack.

[tex]\text{The number of fork packages}=\frac{200}{9}[/tex]

[tex]\text{The number of fork packages}=22.22222[/tex]

Since forks come in package of 9, so cafeteria have to buy whole number packages.

Let us round up our answer to the whole number.

[tex]\text{The number of fork packages}=22.22222\approx 23[/tex]

Therefore, school cafeteria should buy 23 packages of forks.

Answer:

23 packages should the cafeteria buy.

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

As per the statement: The school cafeteria needs to buy 200 new forks. If each package contains 9 forks.

then by definition of Proportion;

[tex]\frac{1}{9} = \frac{x}{200}[/tex]   , where x represents the package

By cross multiply;

200 = 9x

Divide both sides by 9 we get;

[tex]\frac{200}{9} =\frac{9x}{9}[/tex]

Simplify:

[tex]x = \frac{200}{9} =22.222[/tex]

Therefore, 23 package should the cafeteria buy.

Answer:

This system will have a. exactly one solution.

Step-by-step explanation:

When two lines have different slopes it means that they intersect exactly one time.

If they have the same slope, we need to look at the intercept to see if there is none or infinitely many solutions.

However, these have different slopes and therefore have just 1 solution.

The given set of equations has exactly one solution as y = -1 and x = 2.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

To put it another way, the equation needs to be subject to some restrictions.

A linear equation could contain more than one variable. If a variable's maximum power constantly equals one, an equation is considered to be linear.

Given a set of equations,

y = -3x + 5 and y = 3x - 7

By equate,

-3x + 5 = 3x - 7

6x = 12

x = 2 and y = -1

Hence "The given set of equations has exactly one solution as y = -1 and x = 2".

Answer:

37.5

Step-by-step explanation:

The average rate of change is the amount over an interval the outputs change in a ratio to the input change. In a linear function, this is constant and called slope. In all other function, it is called the average rate of change because the rate of change varies over the interval. We use the same formula for the average rate of change as we do slope. First we need both the inout and output values of the function over the interval.

For x=1, [tex]f(1)=5(2^1)=5(2)=10[/tex].

For x=5, [tex]f(1)=5(2^5)=5(32)=160[/tex]

Answer: at this amount, there are 57.5 calories per ounce

therefore, there are 355 calories in 6 ounces of this ice cream

(since 57.5×6=355.0)

Answer:

345 calories

Step-by-step explanation:

Total Calories = 230 calories

Total amount = 4 ounces

TO find how many calories in 6 ounces of the ice cream

For this question we have to find out the number of calories in one ounce of an ice cream firs

as it is given to us that 230 calories in 4 ounces

so no of calories in one ounce = total calories / no of ounces

                                                   =230 / 4

                                                   =57.5 calories / ounce

Now we know that their are 57.5 calories in one ounce of the ice cream

We have to find no of calories in 6 ounces of ice cream

No of calories = 6 * 57.5

                       =345 calories

so amount of calories in 6 ounces are 345 calories

Answer:

In #1, the slope of the line is 3

Step-by-step explanation:

To find the slope of any line, you need to use the points in the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - 2)/(0 - -1)

m = 3/1

m = 3

This means the slope is equal to 3.

The problem can be solved using the power of a point theorem. First, let BD = x and EC = x + 12. Construct an equation: 8x = 6(x+12). Solving for x gives BD = 9 and EC = 21. The length of AC is then 35.

This problem can be solved using the concept of power of a point theorem in circle geometry. The power of a point theorem states that for any point outside a circle, the product of the lengths of the two line segments obtained by drawing secants from that point to the circle are always equal.

To apply this theorem to this problem, we'll first denote BD as x. Because the problem states that EC is 12 more than BD, we can denote EC as x + 12.

Now, using the power of a point theorem, we can write the equation (AD)*(DB) = (AE)*(EC). Substituting in the given values and the values we denoted for DB and EC, we get (8)*(x) = (6)*(x+12).

Solving this equation gives x = 9. Therefore, the length of BD is 9, and the length of EC is 21. To find the length of AC, we add the lengths AE, EC, and AD, which gives us AC = 6 + 21 + 8 = 35.

Answer:

The value for the expression [tex](A+B)^{2}[/tex] is the largest

Step-by-step explanation:

Since both A and B must be greater than 0 and A>B then we can assume the least possible values for B=1 and A=2.

So,

i) 2(A+B) = 2(2+1) = 2*3 = 6

ii) [tex](A+B)^{2}[/tex] = (A+B)*(A+B) = (2+1)*(2+1) = 3*3 = 9

iii) [tex]A^{2} + B^{2}[/tex]  = [tex]2^{2} +1^{2}[/tex] = 4+1 = 5

iv) [tex]A^{2} - B^{2} = 2^{2} - 1^{2}[/tex] = 4-1 =3

Inspecting the answers of the above four expressions, we see that the value for the expression [tex](A+B)^{2}[/tex] is the largest.

Answer: (A+B)^2 is the largest because it equals 9 when A=2 and B=1 are plugged in and the rest are less than 9
