WILL CHOOSE BRAINLIEST! The height of a baseball, h (in feet), as a function of time, t (in seconds), is given by the equation h(t)=-16t²+32t+3. find the average velocity (in ft/sec) of the baseball from t=0 to t=1.
Answer:
Given the equation y = -16t^2 + 96t + 3, we know a = -16, b = 96, c = 3.
Let's solve for h in this problem.
h = -b/2a
h = -(96) / 2(-16)
h = -96 / -32
h = 3 seconds
Now let's add t=3 to our equation:
y = -16t^2 + 96t + 3
y = -16*(3)^2 + 96*(3)+ 3
y = -144 + 288 + 3
We now know that the vertex is (3,147), which means that the ball's maximum height is 147 feet.
Answer:
Step-by-step explanation:
Find the height at h(0) and h(1)
h(0) = 3 ft
h(1) = -16 + 32 + 3 = 19 ft
It takes 1 second to go from 3 feet to 19 feet
(19-3) ft / 1 sec = 16 ft/sec

Draft a small paragraph Explaining the concept of ground speed and horizontal distance traveled or distance traveled over the earth. Consider in your description what information is needed to calculate distance traveled.
Answer:
miles to travel directly south = 54 miles (to the nearest mile)
extra miles = 68 miles (nearest mile)
Step-by-step explanation:
We need to find the height of the right triangle in the diagram.
To do this, use the sine trig ratio.
[tex]\sin(x)=\sf\dfrac{O}{H}[/tex]
where:
[tex]x[/tex] is the angleO is the side opposite the angleH is the hypotenuseGiven:
[tex]x[/tex] = 27°
O = height (h)
H = 120 miles
Substituting the given values into the formula:
[tex]\implies \sin(27^{\circ})=\sf\dfrac{h}{120}[/tex]
[tex]\implies \sf h=120 \sin(27^{\circ})[/tex]
[tex]\implies \sf h=54.47885997...[/tex]
Therefore, the shipmate will have to travel 54 miles (to the nearest mile) directly south.
To find the number of extra miles have been traveled, we first need to find the base length of the right triangle.
To do this, use the cos trig ratio.
[tex]\cos(x)=\sf\dfrac{A}{H}[/tex]
where:
[tex]x[/tex] is the angleA is the side adjacent the angleH is the hypotenuseGiven:
[tex]x[/tex] = 27°A = base (b)H = 120 milesSubstituting the given values into the formula:
[tex]\implies \cos(27^{\circ})=\sf\dfrac{b}{120}[/tex]
[tex]\implies \sf b=120 \cos(27^{\circ})[/tex]
[tex]\sf \implies b=106.9207829...[/tex]
Therefore, the base of the right triangle is 106.9207829... miles
To find the extra miles, sum the hypotenuse and the height of the triangle, then subtract the base.
Extra miles = (120 + 54.47885997... ) - 106.9207829...
= 67.55807707...
= 68 miles (nearest mile)

Answer:
[tex]Hi!~I~am~beinggreat78,~and~I~will~help~you![/tex]
Let's start by breaking down the problem.
This is how it should look. ↓
[tex]60[/tex] ÷ [tex]20[/tex] ⇒ [tex]+ 3[/tex] ⇒ [tex]x * 5^2[/tex]
What does that x mean? x is just a substituted value for the first 2 equations.
Now, we can solve.
[tex]60[/tex] ÷ [tex]20[/tex] [tex]= 3[/tex]
Add 3
[tex]3 + 3 = 6[/tex]
Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.
[tex]5^2~or~5 * 5 = 25[/tex]
And now for the last step, multiply 25 times 6
[tex]25 * 6 = 150[/tex]
With that information, the problem is solved! Your answer is 150

Calculate the average (arithmetic mean) of the list of numbers shown in the table. (rounded to the nearest tenth A) 10.1 B) 11.0 C)11.1 D)12.3
Answer:
C.
Step-by-step explanation:
When we add up all the numbers we get 111 then we divide it by 10 which gives us 11.1. since we have no value to round to the tenths place, the answer stays the same.
Complete the equation and match it to its corresponding number of solutions.
Answer:
A and infinite solutions
Step-by-step explanation:
4/5x - 8 = 4(1/5x - 2)
4(1/5x - 2)
4/1 x 1/5x = 4/5x
4 x (-2) = -8
Put them together and you get:
4/5x - 8 AND
4/5x - 8 = 4/5x - 8
IF 2 SIDES OF AN EQUATION ARE THE SAME THEN THE ANSWERS ARE INFINITE
YOU CAN TURN THE EQUATION INTO JUST (x = x)
Answer
B and One Solution
Step-by-step explanation:
4/5x - 8 = -(4/5x + 2)
-(4/5x + 2) = -4/5x - 2
ADD 4/5x TO THE BOTH SIDES
8/5x - 8 = -2
ADD 8 TO BOTH SIDES
8/5x = 6
DIVIDE BOTH SIDES BY 8/5 OR 1.6
x = 3.75
You can get through the last one. Reply if you need me to
For this item, enter the answer in the space provided. A college student earns $ 15, 000 working part-time at a bookstore. The student pays 1/10 of the earnings in taxes, spends 2/5 of the earnings on living expenses, and saves the remainder of the earnings. How much money does the student save?
Answer: 10,500
Step-by-step explanation:
How to calculate tax and earning
Given the following paramiters
Total amount earned by the student = $15000
Assume we have the following parameters
Earning paid off in taxes = $1500
Amount spent on living expenses = $3000
Amount she will have left = 15000 - (1500 + 3000)
Amount she will have left = 15,000 - 4500
Amount she will have left = 10,500
Hence the amount she will have left is $10,500
Answer:
$7,500
Step-by-step explanation:
First, find the amount he pays in taxes:
$15,000 x 0.1 = $1,500
Next, find the amount he pays in living expenses:
$15,000 x 0.4 = $6,000
Add the two amounts together:
$1,500 + $6,000 = $7,500
Subtract the combined amount from the original amount to find how much the student saved:
$15,000 - $7,500 = $7,500
Therefore, the college student saves $7,500.

(05.03)Bev has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.
Answer:
220.5 sq feet
Step-by-step explanation:
Given : Bev has to cut her grandma's grass this weekend
Six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.
To Find : Area of Polygon
Solution:
Area of triangle = (1/2) bh
= (1/2) * 15 * 15
= 112.5 sq feet
= (1/2) * 4 * 4
= 8 sq feet
Area of rectangle = 25 x 4 = 100 sq feet
Total area =112.5 + 8 + 100
= 220.5 sq feet
Area of Polygon = 220.5 sq feet
Answer:
398 ft²
Step-by-step explanation:
Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.
Triangle area = 1/2·bh
Rectangle area = bh
___
So, the first triangle has an area of ...
1/2·(20 ft)(20 ft) = 200 ft²
The second triangle has an area of ...
1/2·(6 ft)(6 ft) = 18 ft²
The rectangle has an area of ...
(30 ft)(6 ft) = 180 ft²
And the area total is ...
200 ft² +18 ft² +180 ft² = 398 ft²
Solve f(x)=2, if f(x)=1/2x-3
Answer:
10
Step-by-step explanation:
Solve f(x)=2, if f(x)=1/2x-3
Both equations are set to equal f(x) so the solution would be the two equations set to equal each other
2 = 1/2x - 3
==> add 3 to both sides
5 = 1/2x
==> multiply both sides by 2
10 = x
Answer:
x = 10
