Answer: width = 82.50 m

Step-by-step explanation:

P = 2l x 2w

425 = 2(130) + 2w

425 - 260 = 2w

w = 165 / 2 = 82.50

What are the zeros of f(x) = x2 - 8x+16?

Stels [109]

Answer:

x=4

Step-by-step explanation:

f(x) = x^2 - 8x+16

Set equal to zero

0 = x^2 -8x +16

Factor

what 2 numbers multiply to 16 and add to -8

-4*-4 = 16

-4+-4 = -8

0= (x-4)(x-4)

Using the zero product property

x-4 = 0 x-4 =0

x=4 x=4

What is the surface area of a sphere with the given dimension? Express your answer to nearest hundredth. Use 3.14 for pi. Radius

pav-90 [236]

Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r.
$4 \pi (5^2) = 4(3.14)*25 = 100 * 3.14 = 314$
I got 314 cm^2 is the surface area, but it always helps to double check work! Hope this helps!
