**Answer:**

5x^2 +28x - 100

**Step-by-step explanation:**

f(x)=7x^2−2 and g(x)=2(x−7)^2

First simplify g(x)

g(x) = 2 ( x-7)(x-7) = 2( x^2 - 7x -7x +49) = 2(x^2 -14x +49) = 2x^2 -28x +98

Now f(x) - g(x)

f(x) - g(x) = 7x^2−2 - (2x^2 -28x +98)

Distribute the minus sign

= 7x^2−2 - 2x^2 +28x -98

Combine like terms

= 5x^2 +28x - 100

Write an exponential function in the form y=ab^xy=ab

x

that goes through points (0, 18)(0,18) and (2, 288)(2,288).

**Answer:**

[tex]y = 18*4^x[/tex]

**Step-by-step explanation:**

We want an **exponential equation** in the following format:

[tex]y = ab^x[/tex]

**Point (0,18):**

This means that when [tex]x = 0, y = 0[/tex]. So

[tex]y = ab^x[/tex]

[tex]18 = ab^0[/tex]

[tex]a = 18[/tex]

So

[tex]y = 18b^x[/tex]

**Point (2,288):**

This means that when [tex]x = 2, y = 288[/tex]. So

[tex]y = 18b^x[/tex]

[tex]18b^2 = 288[/tex]

[tex]b^2 = \frac{288}{18}[/tex]

[tex]b^2 = 16[/tex]

[tex]b = 4[/tex].

So

[tex]y = 18*4^x[/tex]

Find the volume of a sphere with a diameter of 6.2 in.

**Answer: its 23 meters**

**Step-by-step explanation:**

The volume of a **sphere **with a **diameter **of 6.2 in is 39.72π

The volume of a **sphere **is defined as the total amount of **capacity **applied in a **sphere **that can be calculated using the **volume **formula for the sphere which is V = (4/3)πr3.

The **radius **of the **sphere **is;

[tex]\rm Radius =\dfrac{Diameter}{2}\\\\Radius=\dfrac{6.2}{2}\\\\Radius=3.1[/tex]

The **volume **of the **sphere **is;

[tex]\rm Volume =\dfrac{4}{3}\pi r^3\\\\Volume =\dfrac{4}{3}\pi (3.1)^3\\\\Volume = 39.72\pi[/tex]

Hence, the volume of a **sphere **with a **diameter **of 6.2 in is 39.72π.

Suppose two rectangles have the same area. Must they have the same length and width? Explain.

**Answer:**

no

**Step-by-step explanation:**

Two rectangles having the same area do not need to have the same length and width. The length and width of the rectangle are just factor pairs of the number that is the area. For example, if the area was 12, the side lengths would be 1 and 12, 2 and 6, or 3 and 4. As you can see, those aren't the same lengths and widths. A rectangle may be 1x12 and another may be 3x4, but they have the same area.

If x= 2/3 and x = – 3 are roots of the quadratic equations ax2 + lx + b = 0, find the values of a and b.

**Answer:**

**Step-by-step explanation:**

ax² + 7x + b

a population has a standard deviation of 20.2. what is the standard error of the sampling distribution if the sample size is 121? round your answer to two decimal places.

A) 1.84

B) 1.44

C) 1.55

D) 1.68

**Answer:**

A) 1.84

**Step-by-step explanation:**

I just took the quiz

The **standard error** of the sampling size is 121 is** 1.84 **

"a measure of the statistical accuracy of an estimate, equal to the standard deviation of the theoretical distribution of a large population of such estimates."

"In the **standard error **formula, the factor sqrt[ (N - n ) / (N - 1) ] is called the finite population correction or fpc. When the population size is very large relative to the sample size, the fpc is approximately equal to one; and the **standard error **formula can be approximated by:

σx = σ / sqrt(n)."

Given,

**Standard deviation **of the sample is **20.2**

and** sample size** is = **121 **

Standard error is = [tex]\sigma/\sqrt(n)[/tex]

i.e. **standard error** = [tex]20.2/\sqrt(121)[/tex] = 20.2/ 11 = **1.84**

Hence,** option A** is true.

Remember that sine is y while cosine is x.

Since sine is y, It'd be a horizontal line. And since it's a horizontal line, it intersects two points in a unit circle.

The perimeter of a triangle is 64 in. The longest side is 14 in. Longer than the medium side, and the medium side is 7 in. more than the shortest side. Find the length of each side of the triangle

**Answer:**

longest side =33

medium side =19

shortest side = 12

**Step-by-step explanation:**

Let medium side be x

then longest side =14 +x

shortest side = x-7

we know that ,

perimeter =sum of all side

or, 64 = 14+ x + x + x -7

or, 64 - 7 = 3x

or, 57 = 3x

or, 57÷3 = x

or, x = 19

then

medium side =x = 19

longest side =x+14 =33

shortest side = x- 7 = 12 #

Chloe has 3 red pencils, 5 blue pencils, and 1 yellow pencil in her backpack. She chooses one pencil at random, puts it back, and then chooses another pencil .

The probability that Chloe chooses a blue pencil and then a red pencil is

The probability that Chloe chooses the yellow pencil and then a blue pencil is

No links please :)

Answer:

A) P(chooses a blue pencil and then a red pencil) = 5/27

B) P(chooses yellow then blue) = 5/81

Step-by-step explanation:

She has 3 red pencils, 5 blue pencils, and 1 yellow pencil in her backpack

Thus;

total number of pencils = 3 + 5 + 1 = 9 pencils

A) probability that she chooses a blue pencil and then a red pencil;

P(blue) = 5/9

Now she puts it bag after choosing which means the sum is back to 8 pencils.

Thus, if she now chooses a red pencil, then P(red) = 3/9 = 1/3

Thus;

P(chooses a blue pencil and then a red pencil) = 5/9 × 1/3

P(chooses a blue pencil and then a red pencil) = 5/27

B) probability that Chloe chooses the yellow pencil and then a blue pencil;

Similar to A above;

P(yellow) = 1/9

P(blue) = 5/9

P(chooses yellow then blue) = 1/9 × 5/9

P(chooses yellow then blue) = 5/81
