Answer:

Height of Flagpole: 24.03 feet

Length between tip of flagpole and tip of shadow: 46.67 feet

Step-by-step explanation:

So the angle of elevation (31°) is facing directly opposite of the flagpole. The shadow of the flagpole (40 ft) is adjacent to the angle of elevation. Therefore, the tangent function incorporates both the opposite and adjacent sides of the right triangle created. We would then make the equation and solve for the height of the flagpole which is the opposite side (h in this case):

tanθ = opposite/adjacent

tan(31°) = h/40

40tan(31°) = h

24.03442476 = h

h ≈ 24.03

Therefore, the height of the flagpole is about 24.03 ft.

As for your bonus question, the length of the tip of the flagpole to the tip of the shadow would be the hypotenuse of the triangle created, which can easily be found using the Pythagorean Theorem (using exact values):

a² + b² = c²

(40tan(31))² + (40)² = c²

577.6535736 + 1600 = c²

2177.6535736 = c²

46.66533589 = c

c ≈ 46.67

Therefore, the length from the tip of the flagpole to the tip of the shadow is 46.67 ft.

Marsha Waite borrows $7,000 and agrees to pay it back in 2 years if the simple interest rate is 15%
I am Lyosha [343]

Answer:

Marsha must pay in 2 years \$9,100

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A  is the amount of money to pay

P is amount of money borrowed  

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=2\ years\\ P=\$7,000\\ A=?\\r=15\%=15/100=0.15

substitute in the formula above

A=7,000(1+0.15*2)

A=7,000(1+0.30)

A=7,000(1.30)

A=\$9,100

therefore

Marsha must pay in 2 years \$9,100

22. Find the balance in an account with $900 earning 6.5% compounded<br> quarterly after 4 years
Helen [10]

Answer:

$1,164.80

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, we need to change 6.5% into a decimal:

6.5% -> \frac{6.5}{100} -> 0.065

Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:

A=900(1+\frac{0.065}{4})^{4(4)}

A=1,164.80

The balance after 4 years will be $1,164.80
