Answer:

= -42a⁶

Step-by-step explanation:

-7a⁵. 6a = -7a⁵ × 6a

Therefore;

We multiply; -7 × 6 = -42

then; a⁵ × a = a⁶

Thus; we have -42 a⁶

Hence; <u>-7a⁵ × 6a = -42 a⁶</u>

Answer:

-42a⁶ is the answer.

Step-by-step explanation:

we have given  the expression:

-7a⁵· 6a

we have to write this product in its simplest form

To write it in simplest form we use the formula mentioned below :

xᵃ .  xᵇ = x ᵃ⁺ᵇ

using above fomula we have:

(-7)(6)a⁽⁵⁺¹⁾

-42a⁶ is the product in simplest form.

Jim's backyard is a rectangle that is 15 5/6 yards long and 10 2/5 yards wide. Jim buys sods in pieces that are 1 1/3 yards long
Ne4ueva [31]

We are given

Jim's backyard:

Length is

L=15\frac{5}{6} =\frac{95}{6} yards

width is

W=10\frac{2}{5} =\frac{52}{5} yards

Since, this is rectangle

so, we can find area of rectangle

A=L*W

A=(\frac{95}{6})*(\frac{52}{5})

A=\frac{494}{3} yard^2

Area of one sod:

length is

l=1\frac{1}{3} =\frac{4}{3} yards

width is

w=1\frac{1}{3} =\frac{4}{3} yards

Since, it is rectangle in shape

so,

Area=l*w

A=\frac{4}{3}*\frac{4}{3}

A=\frac{16}{9}yard^2

Number of pieces of sod:

we can use formula

Number of pieces of sod = (area of Jim's backyard)/(area of one sod)

N=\frac{\frac{494}{3} }{\frac{16}{9} }

now, we can simplify it

N=\frac{741}{8} pieces need ..............Answer

After t seconds, a ball in the air from the ground level reaches a height of h feet given by the equation h= 144t-16t^2 . After
Effectus [21]
H=0
Therefore:
144t-16t²=0
t (144-16t)=0
We have two equations:
1)
t=0    (when the ball is released)
2)
144-16t=0
-16t=-144
t=-144 / -16=9  (this is the time )

Answer: the ball hit the ground in 9 s.
