Answer:

-28x^4y^6

Step-by-step explanation:

The given expression is

-4x^3y^2(7xy^4)

We need to place the indicated product in the proper location on the grid.

The given expression can be rewritten as

(-4\times 7)(x^3x)(y^2y^4)

-28(x^3x)(y^2y^4)

Using the product property of exponent, we get

-28\times x^{3+1}\times y^{2+4}          [\because a^ma^n=a^{m+n}]

-28\times x^{4}\times y^{6}

-28x^{4}y^{6}

Therefore the answer of given product is -28x^{4}y^{6}.

Scott wants to buy fencing to place around a circular rock garden. The diameter of the circle is 16 feet. Using 3.14 for π, Calc
denpristay [2]

Answer:

200.96 square feet

Step-by-step explanation:

The amount of fencing Scott will need to buy can be gotten by calculating the area of the circular rock garden .

Area of a circle is given by

Pi r^2

Where

r = radius

Given diameter of 16 feet

r = diameter/2

= 16/2

= 8 feet

Pi = 3.14

Therefore,

Area = 3.14 x 8^2

= 3.14 x 8 x 8

= 200.96 square feet

The amount of fencing Scott will need to buy is 200.96square feet

What is the x-intercept of the line with the equation -2x+1/2y=18
Mkey [24]

The x-intercept is a point on the x-axis.
y=0 at every point on the x-axis.

                                       -2x + 1/2(0) = 18

                                       -2x              =  18

Divide each side by  -2 :    x = -9
