Answer:

B

Step-by-step explanation:

(7×2)⁶

when we put a number to the power of something, we need to include the whole number. bit just a part of it.

so, it must be 7⁶×2⁶

just think about the simple example 6², which we could write as (2×3)².

would it be sufficient to e.g. square only one of the factors ?

6² = 36

but e.g. 2×3² = 18. so, that's really not it.

or add the two factors and then square them ?

2+3 = 5. 5² = 25. so, that's not it either.

or multiply the exponent in ?

2×3×2 = 12. so that's not it either.

no, it truly is you need to do the operation to all parts.

2²×3² = 4×9 = 36. yes, that fits.

therefore, B is the right answer.

Tiffany kicks a soccer ball off the ground and in the air, with an initial velocity of 28 feet per second. Using the formula H(t
Sedaia [141]

Answer:

The maximum height of soccer ball  is 12.25 ft.

Step-by-step explanation:

It is given that Tiffany kicks a soccer ball off the ground and in the air, with an initial velocity of 28 feet per second. It means v = 28 ft.

Given formula is

H(t)=-16t^2+vt+s

The initial height of ball is 0.

H(0)=-16(0)^2+v(0)+s

0=s

The height of ball defined by the function

H(t)=-16t^2+(28)t+0

H(t)=-16t^2+28t

It is a downward parabola and the vertex of a downward parabola is the point of maxima.

The vertex of a parabola f(x)=ax^2+bx+c is

(\frac{-b}{2a},f(\frac{-b}{2a}))

\frac{-b}{2a}=\frac{-28}{2(-16)}=0.875

H(0.875)=-16(0.875)^2+28(0.875)=12.25

Therefore the maximum height of soccer ball  is 12.25 ft.

Urgent! Will award brainliest...<br> Factor the following polynomial:<br> <img src="https://tex.z-dn.net/?f=3a%5E%7B2%7D-21a%2B3
umka2103 [35]

Answer:

3 (a-2) (a-5)

Step-by-step explanation:

The first step is to find the GCF. Here, it's 3.

3(a^2-7a+10)

Then, you factor the polynomial in the parenthesis.

To find the factors, you will need to find 2 numbers that add to -7, and multiply to 10. -2 and -5 add to -7 and multiply to 10. Now, replace -7a with the factors.

a^2-2a-5a+10

This of this polynomial as 2 problems.

a^2-2a        -5a+10

Then, factor again.

a^2-2a        -5a+10

a(a-2)       -5(a-5)

Then, you keep the factors in parenthesis, and combine the numbers on the outside.

(a-2)(a-5)(a-5)

Since, there are 2 of the same factor, you only need one.

(a-2)(a-5)

BUT REMEMBER!! In the very beginning, we had a 3 that we took out, we STILL need to add that to the final answer. The <u>final answer</u> is:

3 (a-2) (a-5)

Vladimir79 [104]
A- the length of the side of a square
P = 16

P = 4a → 4a = 16  |:4 → a = 4

The diagonal of the square: d = a√2

therefore d = 4√2
