find f(g(-6)

Answers

Answer:

[tex]f(g(-6))=2\sqrt{10}[/tex]

Step-by-step explanation:

first we need to find g(-6)

[tex]g(x)= x^2\\\\g(-6)=(-6)^2\\\\g(-6)=36[/tex]

so g(-6)=36

so we need to find f(36)

[tex]f(x)=\sqrt{x+4} \\\\f(36)=\sqrt{36+4} \\\\f(36)=\sqrt{40}\\\\f(36)=\sqrt{4}* \sqrt{10} \\\\f(36)=2\sqrt{10}[/tex]

so that's answer

Hadley buys 7 boxes of markers with 8
in each box. Delaney buys 6 boxes of
markers with 12 markers in each box.
How many markers did Hadley and
Delaney buy in all?

Answers

Answer:

128 markers.

Step-by-step explanation:

7 x 8 =  56

12 x 6 = 72

72+ 15 = 87

Hadley and Delaney therefore bought 128 markers all in total.

Hope I helped ! :))))))

The amount of markers Hadley and Delaney bought in all is equal to 128 markers.

Given  the following data:

Hadley = 7 boxes of markers with 8  in each box.Delaney = 6 boxes of  markers with 12 markers in each box.

To determine the amount of markers Hadley and Delaney bought in all:

First of all, we would determine the total number of marker in each box.

For Hadley:

[tex]Hadley = 7 \times 8[/tex]

Hadley = 56 markers

For Delaney:

[tex]Delaney = 6\times 12[/tex]

Delaney = 72 markers

Now, we can find the total markers:

[tex]Total \;markers = Hadley + Delaney\\\\Total \;markers = 56+72[/tex]

Total markers = 128 markers

a body of mass 2kg travelling with a velocity of 10 m/s what is the momentum this body colloids with another body of equal mass travelling in the same direction with a velocity of 5m/s what is the total momentum of the 2 objects before and after coliision

Answers

Your question has been heard loud and clear.

M1 = 2kg , M2=2kg , V1=10m/s V2=5m/s

Total momentum before collision = M1V1+M2V2 = 2*10 + 2*5 = 30kgm/s  

Now , by law of conservation of momentum ,

Total momentum before collision = total momentum after collision

Therefore , total momentum of objects before and after collision = 30kgm/s

Find the distance between (-4,-1) and (-3,-1).

Answers

Answer:

The answer is 1 unit

Step-by-step explanation:

The distance between two points can be found by using the formula

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

Find the measure of AB¯¯¯¯¯¯¯¯. A. 14 B. 22 C. 21 D. 20

Answers

Answer:

C. 21

Step-by-step explanation:

We use the Power of Point theorem, which states that for points A, B, C, D, and E oriented in the way shown in the attachment:

BC * AC = DC * EC

Here:

AC = AB + BC = (2x + 5) + 9 = 2x + 14

BC = 9

DC = 10

EC = KC = (1 + 2x) + 10 = 2x + 11

So plug all these in:

BC * AC = DC * EC

9 * (2x + 14) = 10 * (2x + 11)

18x + 126 = 20x + 110

2x = 126 - 110 = 16

x = 8

Put this back into the expression for AB:

AB = 2x + 5 = 2 * 8 + 5 = 16 + 5 = 21

The answer is thus C.

Cube

The side length is 0.5 m.

V = a³

V = (0.5 m)³

Find all real zeros of the function f(x)= 12 A. 5,7 B. 12 C. 1 D. none

Answers

Answer:

D. None

Step-by-step explanation:

Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x

f(x) = 12x⁰

From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.

From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.

Hence, there are no real zeros of the function.

Answers

Complete Question

Paj is filling a 9-cubic-inch flower pot with soil from small bags. Each bag of soil contains 2 2/3  cubic inches of soil. Exactly how many bags of soil are needed for Paj to fill the flower pot?

Answer:

[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]

Step-by-step explanation:

Given

[tex]Flower\ Pot = 9 in^3[/tex]

[tex]Small\ Bag = 2\frac{2}{3} in^3[/tex]

Required

How many bag of soil can fill the flower pot

To solve this,we simply divide the volume of flower pots by the small bags. This is done as follows;

[tex]Number\ of\ Bags = \frac{Flower\ Pot}{Small\ Bag}[/tex]

[tex]Number\ of\ Bags = \frac{9 in^3}{2\frac{2}{3} in^3}[/tex]

Convert fraction

[tex]Number\ of\ Bags= \frac{9 in^3}{\frac{8}{3} in^3}[/tex]

[tex]Number\ of\ Bags = 9 in^3/\frac{8}{3} in^3[/tex]

[tex]Number\ of\ Bags = 9 * \frac{3}{8}[/tex]

[tex]Number\ of\ Bags = \frac{9 * 3}{8}[/tex]

[tex]Number\ of\ Bags = \frac{27}{8}[/tex]

[tex]Number\ of\ Bags = 3\frac{3}{8}[/tex]

Hence, the number of bags needed is  [tex]3\frac{3}{8}[/tex]

We can now substitute 15 in as d, to see how much this will cost.

[tex]20\cdot15 + 7\\\\300+7\\\\307[/tex]

So the total cost will be $307.

Since $307 is more than $250, she does not have enough money.

An experiment's or random trial's sample space is the set of all conceivable outcomes or results. The correct option is C.

What is a sample?

A sample is a statistically significant subset of a larger population. The utilisation of samples enables researchers to conduct investigations with more manageable data and more quickly. Randomly chosen samples exhibit little bias if they are large enough, but obtaining such a sample can be costly and time-consuming.

Given that a population consist of 85,000 people. Now, the number of members of the population that being surveyed could result in a parameter but not a sample static is 8500. This is because a parameter is a value that describes a specific attribute of the population as a whole. A sample survey cannot provide this information. To determine the real value of a parameter, the entire population must be examined.

Hence, the correct option is 85,000.
