Answer:
D. The ball was thrown from an initial height of 3 feet.
Step-by-step explanation:
The generic form of the equation for (vertical) ballistic motion is ...
[tex]h(t)=-\dfrac{1}{2}gt^2+v_0t+h_0[/tex]
where g is the acceleration due to gravity, usually approximated as 32 ft/s², v₀ is the initial upward velocity, and h₀ is the initial height.
The given equation matches the situation where the object was launched vertically at the rate of 40 ft/s from a height of 3 ft.
The 3 represents an initial height of 3 feet.
8. Subtact (7x – 10) – (-6x – 8).
Answer:
13x - 2
Step-by-step explanation:
7x - -6x = 7x + 6x = 13x.
-10 - -8 = -10 + 8 = -2
13x - 2
Answer:
13x - 2
Step-by-step explanation:
( 7x - 10 ) - ( -6x - 8 )
First, distribute the minus sign outside of the second parenthesis. Multiply each term within the second parenthesis by the minus sign.
( 7x - 10 ) + ( (-1)(-6x) + (-1)( -8))
Simplify,
( 7x - 10 ) + ( 6x + 8 )
Remove parenthesis,
7x - 10 + 6x + 8
Simplify, combine like terms,
7x - 10 + 6x + 8
13x - 2

Answer: D
Step-by-step explanation: You need to divide the figure into 2 parts. You need to ignore 13 m And use the other numbers. Figure A is 9x3x4 and Figure B is 7x4x4 because the other 4 is at the bottom. I hope this helps. Good luck!

Determine how much you would recieve in return for a 8 month, $500 loan to a friend if you charged the 3% annual interest. Show your work.
Answer: See explanation
Step-by-step explanation:
We are going to solve this by using the Simple interest formula which is:
= Principal × Rate × Time
= 500 × 3% × 8/12
= 500 × 0.03 × 2/3
= 10
Therefore, the interest will be $10 ane the total amount that'll be paid back will be:= $500 + $10 = $510

This is the pond in a shape of a prism, it is completely full of water. Colin uses a pump to empty the pond. The level goes down by 20cm in the First 30min Work put how many minutes Colin has to wait for the pond to completely empty
Answer:
150 minutes
Step-by-step explanation:
P.S - The exact question is -
Given - This is the pond in a shape of a prism, it is completely full of
water. Colin uses a pump to empty the pond. The level goes
down by 20 cm in the first 30 min.
To find - Work put how many minutes Colin has to wait for the pond
to completely empty.
Proof -
Given that,
Height of prism = 1 m
Also,
Base of the prism is trapezium and
Sides of the trapezium are 0.6 m and 1.4 m
Height of trapezium is 2 m
We know that,
Area of trapezium = [tex]\frac{1}{2}[/tex]× (sum of sides)× height
= [tex]\frac{1}{2}[/tex]× (0.6 + 1.4)× 2
= [tex]\frac{1}{2}[/tex]× (2)× 2
= 2 m²
⇒Area of trapezium = 2 m²
Now,
Volume of prism = Area of trapezium × height of prism
= 2 m² × 1 m
= 2 m³
⇒Volume of prism = 2 m³
Now,
Given that the level goes down by 20 cm in the first 30 min
We know
100 cm = 1 m
⇒1 cm = [tex]\frac{1}{100} m[/tex] = 0.01 m
⇒20 cm = 20×0.01 m = 0.2 m
⇒The level goes down by 0.2 m in the first 30 min.
Also,
we know that height of water = height of prism = 1 m
So, the remaining water left in the pond = 1 m - 0.2 m = 0.8 m
Also,
Volume of Remaining water = Area of trapezium × height
= 2 m² × 0.8 m
= 1.6 m³
⇒Volume of Remaining water = 1.6 m³
Now,
Volume of emptied water = Total Volume - Volume of Remaining water
= 2 m³ - 1.6 m³
= 0.4 m³
⇒Volume of emptied water = 0.4 m³
Now,
0.4 m³ water will be empty in 30 minutes
⇒ 1 m³ water will be empty in [tex]\frac{30}{0.4}[/tex] = 75 minutes
⇒1.6 m³ water will be empty in 1.6 × 75 = 120 minutes
∴ we get
The remaining water is empty in 120 minutes
So,
Total pond is empty in 120 + 30 minutes
⇒Total pond is empty in 150 minutes

The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation.
A. 10; your car travels for 10 hours.
B. 212; your car travels 212 miles.
C. [tex]\frac{53}{1}[/tex], Your car travels 53 miles every 1 hour.
D. [tex]\frac{1}{53}[/tex]; Your car travels 53 miles every 1 hour.
Answer:
The answer is D) The car travels 53 mph(Miles Per Hours).
212/4 = 53
318/6 = 53
424/8 = 53
530/10 = 53
Step-by-step explanation:
Answer:
C) rate of change is 53, your car travels 53 miles every 1 hour .
Step-by-step explanation:
Given : Table for time and distance.
To Find : The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation.
Solution : We have given that Table for time and distance.
rate of change= (change in y)/(change in x) .
rate of change=(212)/(4) .
rate of change = 53.
rate of change= (318)/(6).
rate of change = 53
rate of change = (424)/(8).
rate of change = 53.
rate of change = (530)/(10) .
rate of change = 53.
Therefore, C) rate of change is 53, your car travels 53 miles every 1 hour .

Find the slope of the line in the graph.
Answer:
rise over run 2/10 siplified 1/5
Step-by-step explanation:
3(4y + 7) = 69
full answer
Answer:
y=4
Step-by-step explanation:
First, you should simplify this equation. To do that, we need to multiply 3 by 4y and 3 by 7. This will make the equation 12y+21=69. Subtract 21 from both sides to isolate y. This will make the equation 12y=48. You want the y to be by itself so you have to divide 12 by each side to get y=4. Therefore, the answer is y=4.
Hope this helps

The product of two consecutive negative even integers is 24. Find the largest integer.
Answer:
-4
Step-by-step explanation:
ok negative times negative = positive
and factors of 24 are
1,2,3,4,6,8,12,24
4 x 6 are the two consecutive EVEN numbers
so turn it to negative
-4 x -6 = 24
The largest is -4
Please help me with this homework using the substitution method
Answer:
(5, -2)
Step-by-step explanation:
Let's solve the first equation for x: If x + y = 3, and if we subtract y from both sides, we get x = 3 - y. Next, substitute 3 - y for x in the second equation:
3(3 - y) + 2y = 11, or
9 - 3y + 2y = 11
Combining like terms: -3y + 2y = 11 - 9, or
-y = 2, or y = -2.
Then, from the equation x = 3 - y, which we found earlier,
x = 3 - (-2) = 5
Then the solution is (5, -2)
