Answer:

  7.06

Step-by-step explanation:

This triangle can be solved a couple of ways. In the end, they amount to the same thing.

1) The area is ...

  A = 1/2bh = 1/2(8)(15) = 60 . . . using DG as the base

Using GE as the base, the height (DF) is ...

  A = (1/2)(17)(DF)

  2(60)/17 = DF = 120/17

  DF ≈ 7.06

__

2) Using similar triangles, we can find the ratio of the long side to the hypotenuse as ...

  (long side)/(hypotenuse) = DE/GE = DF/DG

  DF = DG(DE/GE) = 8(15/17) = 120/17

  DF ≈ 7.06

Jimmy invests $15,000 in an account that pays 8.90% compounded quarterly. How long (in years and months) will it take for his in
viktelen [127]
22000=15000(1+.089/4)^4t
22/15=(1.02225)^4t
log(22/15)=4tlog1.02225
(log(22/15)/4log1.02225)=t
(.16633/.038228)=t
t=4.35 years or 4 years and approximately 4 months

7. Using the distance formula, calculate how far Hector threw the ball. (4 points: 2
iragen [17]

The required distance covered is 90 units

<h3>Distance formula</h3>

The formula for calculating the distance between two points is expressed as shown:

  • D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The required coordinates missing are (0, 42.78) and (90.42.78). Substiute the coordinate into the formula:

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

D=\sqrt{(42.78-42.78)^2+(90-0)^2}\\D=\sqrt{(0^2+(90)^2}\\D = 90 units

Hence the required distance covered is 90 units
