F(x) = 10-x and g(x) = x2 + 1<br> What is g(8) + f(7)

Olin [163]

Plug in 8 for g(8) to get 8(2) + 1 which is equal to 17, plug in 7 for f(x) to get 10-7 which is equal to 3. 17 + 3 is equal to 20 which means g(8) + f(7)= 20

Solve -6 4/9-3 2/9-82/9

Gala2k [10]

Answer: The final answer in proper fraction is 169/9

Step-by-step explanation:

Given the expression

-6 4/9-3 2/9-82/9

Firstly let us convert all mixed fraction to proper fraction to further simplify the expression

-58/9 - 29/9 - 82/9

We now have all terms in proper fraction, we can continue by finding the LCM which is 9

= (- 58-29-82)/9

= 169/9

Cylinder A has radius r and height h as shown in the diagram. Cylinder B has radius 4r and height 4h. How many times greater is

svetlana [45]

Answer:

The surface area of Cylinder B is 16 times the surface area of Cylinder A

Step-by-step explanation:

<u>Note</u>: <em>It is assumed we are looking at the total surface area (but the answer would be same for both cases)</em>

<h3>Given</h3>

Cylinders A with radius - r, height - h,
Cylinder B with radius - 4r, height - 4h.

The ratio of total surface areas of cylinder B to A

<h3>Solution</h3>

Total surface area of cylinder A is:

$S_A = 2\pi r(h + r)$

Total surface area of cylinder B is:

$S_B = 2\pi(4r)(4r + 4h) = 8\pi(4)(r + h) = 32\pi(r + h)$

Find the ratio of areas:

$\cfrac{S_B}{S_A} =\cfrac{32\pi(r+h)}{2\pi(r+h)} =16$
