To solve this completion exercise you must apply the proccedure shown below:

1. You have the first function:

y=-0.2x²

When you give different values to "x" and plot it as it is shown in the graph attached, you obtain a parabola.

2. Now, you have the second function:

y=x²

When you give different values to "x" and plot it as it is shown in the graph attached, you obtain a parabola.

3. When you see the two graphs attached, you can conclude the the answer is the option D):

Craig’s Kimbrell of the Atlanta braves, can throw his fast ball at 102 miles per hour. Convert this rate to feet per second

omeli [17]

Firstly, you change it to miles per second and then to feet
102miles per hour(60×60s)
102 per 120s
Divide
102÷120
=0.85miles per second
Convert to feet
=4488 feet per second

A frog is climbing out of a well that is 11 feet deep. The frog can climb 3 feet per hour but then it rests for an hour, during

Dimas [21]

Answer:

It takes the frog 7 hours to get out of the well.

Step-by-step explanation:

We know that the well is 11 feet deep and the frog can climb 3 feet per hour.

Each time it climbs, it rests for an hour, and decreases its height by 1 foot.

So, if the frog reaches 3 feet in the first hour, then in the next hour it is 2 feet.

Lets calculate with the same pattern:

1st hour: 3 feet

2nd hour: $3-1=2$ feet

3rd hour: $2+3=5$ feet

4th hour: $5-1=4$ feet

5th hour: $4 +3= 7$ feet

6th hour: $7-1=6$ feet

5th hour: $6+3=9$ feet

6th hour: $9-1=8$ feet

7th hour: $8+3= 11$ feet

Therefore, it takes the frog 7 hours to get out of the well.

Find the exact value

Mnenie [13.5K]

By using properties for trigonometric functions and trigonometric expressions, we find that the exact value of the sine of the angle 5π/12 radians is $\frac{\sqrt{2+\sqrt{3}}}{2}$ .

<h3>How to find the exact value of a trigonometric expression</h3>

Trigonometric functions are trascendent functions, these are, that cannot be described algebraically. Herein we must utilize trigonometric formulae to calculate the exact value of a trigonometric function:

$\sin \frac{5\pi}{12} = \sqrt{\frac{1 - \cos \frac{5\pi}{6} }{2} }$
