Answer:

The pyramid and cones are alike because their lateral faces meet at a vertex. Also, a pyramid becomes a cone as the number of sides of its base becomes larger and larger.

The larger of two numbers is five more than the smaller. Twice the larger is twenty less than four times the smaller. Find the n
lesantik [10]

Answer: Small number = 15.

Larger number = 20

Step-by-step explanation:

Let the smaller number be x.

The larger of two numbers is five more than the smaller. Thus, the larger number is x+5.

Twice the larger is twenty less than four times the smaller. This can.be written as:

2(x + 5) = 4x - 20

2x + 10 = 4x - 20

2x - 4x = -20 - 10

-2x = -30

x = 30/2

x = 15

The smaller number is 15

Larger number = x + 5 = 15 + 5 = 20

Find all solution of the following equation in the interval [0, 2pi) No decimals.
Delicious77 [7]

Step-by-step explanation:

<u>Step 1:  Add 2cos(x) to both sides</u>

7cos(x) + 2cos(x) + 9 = -cos(x) + cos(x)

9cos(x) + 9 = 0

<u>Step 2:  Subtract 9 from both sides</u>

9cos(x) + 9 - 9 = 0 - 9

9cos(x) = -9

<u>Step 3:  Divide both sides by 9</u>

9cos(x) / 9 = -9 / 9

cos(x) = -1

<u>Step 4:  Find x</u>

cos^-^1(-1) = x

\pi = x

Answer:  x = \pi
