<u>Algebra I</u>

  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 35x + 25

g(x) = 22x + 18

f(4) is <em>x</em> = 4 for function f(x)

g(10) is <em>x</em> = 10 for function g(x)

<u>Step 2: Find Function Values</u>

<em>f(4)</em>

  1. Substitute in <em>x</em> [Function f(x)]:                                                                           f(4) = 35(4) + 25
  2. Multiply:                                                                                                             f(4) = 140 + 25
  3. Add:                                                                                                                   165

<em>g(10)</em>

  1. Substitute in <em>x</em> [Function g(x)]:                                                                         g(10) = 22(10) + 18
  2. Multiply:                                                                                                             g(10) = 220 + 18
  3. Add:                                                                                                                   g(10) = 238

<u>Step 3: Evaluate</u>

  1. Substitute in function values:                                                                          5(165) + 2(238)
  2. Multiply:                                                                                                             825 + 476
  3. Add:                                                                                                                   1301

The pillars in front of Mr. Jefferson's home are shaped like cylinders with a height of 24 ft and a radius of 8 in. What is the
kkurt [141]

Answer:

The lateral area is 4,608\pi\ in^{2}  or  32\pi\ ft^{2}

Step-by-step explanation:

we know that

The lateral area of a cylinder (pillar) is equal to

LA=2\pi rh

Remember that

1 ft=12 in

<em>Find the lateral area in square inches</em>

we have

r=8\ in

h=24\ ft ----> convert to inches

h=24*12=288\ in

substitute the values

LA=2\pi (8)(288)

LA=4,608\pi\ in^{2}

<em>Find the lateral area in square feet</em>

we have

h=24\ ft

r=8\ in -----> convert to feet

r=8/12=(2/3)\ ft

substitute the values

LA=2\pi (2/3)(24)

LA=32\pi\ ft^{2}
