What is the area of triangle PQR? Round to the nearest tenth of a square unit.

larisa86 [58]

ANSWER

111.3 square units.

EXPLANATION

The formula for calculating the area of a triangle is.

$Area = \frac{1}{2} \times base \times height$
Let us the side of the triangle with side 12 units to be the base of the triangle.

Then the height of the triangle can be determined from the diagram using trigonometry.

$\sin(68 \degree) = \frac{height}{20 }$

$height = 20 \sin(68 \degree)$

$height = 18.54$

We now plug in the values in to the formula to obtain,

$Area = \frac{1}{2} \times 12 \times 18.54$

$Area = 111.3 \: square \: units$

Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How many flowers did she deliver if she made $

lana66690 [7]

Answer:

she delivers 9 flower plugs.

Step-by-step explanation:

in a standard equation the equation would be 21 = 2x + 3 and if you isolate the x you would have to first subtract the 3 from both sides and that would leave you with 18 = 2x and then you have to divide both sides by 2 and get 9=x

Suppose an investment of $5,000 doubles every 12 years. How much is the investment worth after 36 years? After 48 years?

nadezda [96]

This can be done without exponential equations.

It doubles every 12 years so it has doubled in price
5,000 * 2 = 10,000

After 36 years the value has increased 8 times
5,000 * 8 = 40,000

After 48 years the value has increased 16 times
5,000 * 16 = 80,000

Svetlanka [38]

Answer:

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here g(x) = f(x) - 2 ← with c = - 2 < 0

Then g(x) is the graph of f(x) shifted down 2 units
