Without graphing, what is the x-intercept of this function?

Answer:

-7, -2, 4, 5

Step-by-step explanation:

Integers with a dash in the front of them signify a negative. With negative numbers, the higher the value of the accompanying number, the lower value it has as a negative number, so, of course the negative integers would go from the "least" end of the spectrum. Because 7 has a higher positive value than 2, it has a lower negative value, putting -7 on the lower end, following it with the -2. As 5 has a higher positive value than 4, 5 is put on the highest end on the spectrum, with 4 right behind it. With all of these integers settled, we can organize the numbers in the order of -7, then -2, then 4, then 5.

Step-by-step explanation: To write these integers from least to greatest, first draw a number line and graph each of the integers

In the image provided, notice that I've only labeled every other unit on the number line. This  is a labeling technique that we can use to keep things from getting too crowded on the number line.

Now, let's graph our integers.

Integers to the left are always less than integers to to the right. So in this problem, we can see that -7 < -2 < 4 < 5.

Answer:

Y = W = 15 ft.

X= L = 60 ft.

So width is 15 and the length is 60.

Answer: A. 15 feet

Step-by-step explanation:

The formula used to calculate the perimeter of a rectangle is:

[tex]P=2l+2w[/tex]

Where "l" is the lenght of the rectangle and "w" is the width.

You know that the length of this rectangle is 4 times its width. This means that:

[tex]l=4w[/tex]

And you know that the perimeter is 150 feet.

Then, you need to substitute  [tex]l=4w[/tex] and the value of the perimeter into the formula and solve for "w":

[tex]150=2(4w)+2w\\\\150=10w\\\\w=\frac{150}{10}\\\\w=15feet[/tex]

Answer:

The average rate of change is 3

Step-by-step explanation:

0 to 5 is 5 in difference then the change on the next one: 1 to 9 the difference is 8 so the change is 3 and it increases by three on the rest of them.

I'm pretty sure the average rate of change would be 3

Answer:

see explanation

Step-by-step explanation:

Given the recursive formula

[tex]a_{n}[/tex] = 3[tex]a_{n-1}[/tex] + 2 and a₄ = 20

Then working in reverse

3a₃ + 2 = 20 ( subtract 2 from both sides )

3a₃ = 18 ( divide both sides by 3 )

a₃ = 6

3a₂ + 2 = 6 ( subtract 2 from both sides )

3a₂ = 4 ( divide both sides by 3 )

a₂ = [tex]\frac{4}{3}[/tex]

3a₁ + 2 = [tex]\frac{4}{3}[/tex] ( subtract 2 from both sides )

3a₁ = - [tex]\frac{2}{3}[/tex] ( divide both sides by 3 )

a₁ = - [tex]\frac{2}{9}[/tex]

Hence

a₁ = - [tex]\frac{2}{9}[/tex]

a₂ = [tex]\frac{4}{3}[/tex]

a₃ = 6

a1 = (-2/9)

a2 = 4/3

a3 = 6

Hope this helps!

Answer:

So we already knew all three sides, there are more than one way to do it, for example:

sin∠F = HG/HF = 12/13

cos∠F = GF/HF = 5/13

tan∠F = HG/GF = 12/5

ctg∠F = GF/HG = 5/12

All of them will give you the result which is approximately 67°.

I believe the correct answer from the choices listed above is option D. The expression that could be used to determine the average rate at which the object falls during the first 3 seconds of its fall would be  (h(3)-h(0))/3. Average rate can be calculated by the general formula:

Average rate = (change in y-axis) / (change in x-axis)

In this case,

Average rate = (change in height) / (change in time)

The average rate at which the object falls during the first 3 seconds can be calculated using the equation for average rate of change (h(3) - h(0))/3. Using the given function h(t) = 300 - 16t, this comes out to be -16 feet per second.

In this problem, we are given a mathematical model of a falling object, as follows: h(t) = 300 - 16t. Here, the function h(t) represents the height of the object t seconds after it is dropped from a platform 300 feet above the ground.

To determine the average rate at which the object falls during the first 3 seconds, we should use the equation for average rate of change in functions. That is, the change in height divided by the change in time, or (h(3) - h(0))/3.

Let's calculate: h(3) = 300 - 16*3 = 252, and h(0) = 300. Then, the average rate = (252 - 300) / 3 = -48/3 = -16 ft/sec. This indicates that the object falls at an average rate of 16 feet per second during the first three seconds.

for x - 11 = 9 you have to use the addition property of equality add 9 to 11

for 5x + 6x = 22 you have to combine like terms add 5x and 6x to make 11x

Step-by-step explanation:

The area of the shaded triangle = area of ΔABD - area of ΔADC

Answer:

y=9

Step-by-step explanation:

(9,-1) is the answer.

Nicole has 25 ten-dollar bills.

To find out how many ten-dollar bills Nicole has, we can divide the total amount of money she has by the value of each bill.

$250 / $10 = 25

Therefore, Nicole has 25 ten-dollar bills.

Answer in detail:

Nicole has $250 in ten-dollar bills. This means that she has 25 groups of $10.

We can divide $250 by $10 to find out how many groups of $10 she has.

$250 / $10 = 25

Therefore, Nicole has 25 ten-dollar bills.

Another way to look at it is this way:

If Nicole has 1 ten-dollar bill, then she has $10.

If Nicole has 2 ten-dollar bills, then she has $20.

If Nicole has 3 ten-dollar bills, then she has $30.

And so on.

So, to find out how many ten-dollar bills Nicole has, we can simply divide the total amount of money she has by the value of each bill.

Answer:

The distance reduces to 0 as you go from 0° to 90°

Step-by-step explanation:

The question requires you to find the distance using different values of L and check the trend of the values.

Given C=2×pi×r×cos L where L is the latitude  in ° and r is the radius in miles then;

Taking r=3960 and L=0° ,

C=2×[tex]\pi[/tex]×3960×cos 0°

C=2×[tex]\pi[/tex]×3960×1

C=7380[tex]\pi[/tex]

Taking L=45° and r=3960 then;

C= 2×[tex]\pi[/tex]×3960×cos 45°

C=5600.28[tex]\pi[/tex]

Taking L=60° and r=3960 then;

C=2×[tex]\pi[/tex]×3960×cos 60°

C=3960[tex]\pi[/tex]

Taking L=90° and r=3960 then;

C=2×[tex]\pi[/tex]×3960×cos 90°

C=2×[tex]\pi[/tex]×3960×0

C=0

Conclusion

The values of the distance from around the Earth along a given latitude decreases with increase in the value of L when r is constant

Answer:

Option A. is the correct option.

Step-by-step explanation:

As per table given in this question values of the function has been given as

f(x) = -3 for x = -2

We can rewrite the function as f(-2) = -3

As we know inverse of the function means [tex]-2 = f^{-1}(-3)[/tex]

or inverse function g(-3) = -2

and the ordered pair for the inverse function will be (-3, -2)

Similarly other ordered pairs for the inverse function given will be

Therefore, the ordered pairs will be (-3, -2), (3, -1), (9, 0), (15, 1), (21, 2)
