Answer:

89.6 square feet

Step-by-step explanation:

The total area is that of a 5×14 rectangle and a circle with a radius of 2.5 feet:

A = bh +πr^2

= (5 ft)(17 f) +π(2.5 ft)^2

= 70 ft^2 + 6.25π ft^2

≈ (70 +19.6) ft^2 = 89.6 ft^2

The approximate area is 89.6 square feet.

disa [49]

Answer:

The answer to your question is the big dog weighs 120 pounds

Step-by-step explanation:

Data

big dog = b

medium dog = m

small dog = s

Equations

b = 5s

m = 12 + s

s = 2/3 m

Process

1.- Substitute m in the last equation

s = 2/3(12 + s)

s = 24/3 + 2/3s

s - 2/3s = 8

1/3 s = 8

s = 8(3)

s = 24 pounds

2.- Substitute s in the first equation

b = 5(24)

b = 120 pounds

Solve for f. Show your work! 8=f-(13-2)

Nana76 [90]

Answer:

So F=19

Step-by-step explanation:

8=f-(13-2)

8=f-11

+11 +11 You plus 11 by both sides

19=f

You can check you answer by plugging it in

8=19-(13-2)

your answer would still be 19

Is (x+7) a factor of f(x) x3-3x2+ 2x-8?

Snowcat [4.5K]

Answer:

(x+7) is not a factor

Step-by-step explanation:

we know that

If (x+7) is a factor of f(x)

then

For $x=-7, f(-7)=0$

Verify

we have

$f(x)=x^{3}-3x^{2} +2x-8$

Substitute x=-7

$f(-7)=(-7)^{3}-3(-7)^{2} +2(-7)-8$

$f(-7)=-343-147 -14-8$

$f(-7)=--512$

$-512\neq 0$

therefore

(x+7) is not a factor
