Explanation:
Basically a line goes on forever in both directions. A ray only goes off forever in one direction. If we glue together two rays that point in complete opposite directions (eg 1 points north, the other points south) then we form a line.
A line segment is a piece of a line. It doesn't go on forever in either direction. It has 2 endpoints and has a set fixed length. If you know the coordinates of each endpoint, you can use the distance formula to find that length.
4a + 3a
Will give brainliest!!!
Answer:
7a
Step-by-step explanation:
4a + 3a
(4 + 3)a
(7) a
Answer = 7a
Answer:
4a+3a is equivalent to 7a
Step-by-step explanation:
when simplifying you combine like terms. Since 3a and 4a are like terms and their are no exponents, all you have to do is add the coefficients together.
Davis hit a baseball from a height of 3 feet above the ground at an angle of 24 degrees with the horizontal at an initial velocity of 110 feet per second. How far will the ball travel before it hits the ground?
8. Write a parametric equation for the flight of the ball.
9. Find the maximum height of the ball.
10. How many feet did the ball travel horizontally before it hit the ground?
Answer:
The ball travel horizontally before it hit the ground is 34.22 feet.
Step-by-step explanation:
Given that,
Height = 3 feet
Angle = 24 °
Initial velocity = 110 feet/s
We need to write a parametric equation for the flight of the ball
Using given data
[tex]r(t)=u\cos\theta\times t\hat{i}+(h+(u\sin\theta)t-\dfrac{1}{2}gt^2)\hat{j}[/tex]
Put the value into the formula
[tex]r(t)=110\cos24\times t\ i+(3+110\sin24\times t-\dfrac{1}{2}32t^2)j[/tex]
[tex]r(t)=100.4t(i)+(3+44.7t-16t^2)j[/tex]
Now, on differentiating w.r.to t
[tex]v(t)=100.4i+(44.7-32t)j[/tex]....(I)
We need to calculate the time
Using equation (I)
If y'(t)=0, then the ball will be at maximum height
So, [tex]y'(t)=44.7-32t[/tex]
Put the value of y'(t)
[tex]44.7-32t=0[/tex]
[tex]t=\dfrac{44.7}{32}[/tex]
[tex]t=1.4\ sec[/tex]
We need to calculate the maximum height
Using equation of motion
[tex]y(t)=h+ut-\dfrac{1}{2}gt^2[/tex]
Put the value into the formula
[tex]y(1.4)=3+44.7\times1.4-16\times(1.4)^2[/tex]
[tex]y(1.4)=34.22\ feet[/tex]
Hence, The ball travel horizontally before it hit the ground is 34.22 feet.
Sharon has two liabilities: a credit card balance of $1300 and a car loan balance of $4800. Sharon car has a market value of $9000 she also has a balance of $1450 in her saving account and has stocks that are currently worth $1050. What is Sharon’s net worth?
Given:
Sharon has two liabilities: a credit card balance of $1300 and a car loan balance of $4800.
Car = $9000
Balance in her saving account = $1450
Stocks = $1050.
To find:
Sharon’s net worth.
Solution:
Total liabilities = Credit card balance + Car loan balance
= $1300 + $4800
= $6100
Total Assets = Car + Balance in her saving account + Stocks
= $9000 + $1450 + $1050
= $11500
Now,
Net worth = Total assets - Total liabilities
= $11500 - $6100
= $5400
Therefore, Sharon’s net worth is $5400.
Sharon's net worth, based on her assets and liabilities, is $5,400.
What is the net worth?Net worth refers to the difference between an individual's assets and liabilities.
Assets are the properties owned by the individual. Liabilities are the sources of funding for the assets. They are financial obligations owed to outsiders (creditors).
In business, the net worth of an entity is known as equity.
Data and Calculations:Liabilities:Credit card balance of $1300
Car loan balance of $4800
Total liabilities = $6,100
Assets:Sharon's car with a market value of $9000
Savings account balance of $1450
Stocks that are currently worth $1050
Total assets = $11,500
Net worth = $5,400 ($11,500 - $6,100)
Thus, Sharon's net worth is $5,400.

May can do 936 jumping jacks in
6 minutes. Heather can do 616
jumping jacks in 4 minutes. Who
can do the most jumping jacks
per minute?
please help meeee !
Answer:
May
Step-by-step explanation:
936 ÷ 6 = 156
616 ÷ 4 = 154
Answer: May
May can do 936 jumping jacks in
6 minutes. Heather can do 616
jumping jacks in 4 minutes. Who
can do the most jumping jacks
per minute?
If you were to divide 936 by 6, you would get 156. Then, divide 616 by 4, and you would get 154. This gives you how many jumping jacks each of them do in one minute. The answer to May’s equation was more than Hather’s equation, so May can do more jumping jacks than Heather.
Function A(e) represents the surface area of a cube in terms of its edge length, e, and the difference quotient is 12e + 6h. What is the average rate of change in surface area of a cube as the edge length increases from 3 inches to 5 inches?
48 square inches per inch
54 square inches per inch
66 square inches per inch
96 square inches per inch
Answer: 48 square inches per inch
Step-by-step explanation:
The surface area of a cube of sidelength e is:
A(e) = 6*e^2.
The rate of change is:
A'(e) = 2*6*e
The average rate of change between 3 in and 5 in is:
r = (A(5in) + A(3in))/2 = (2*6*5in + 2*6*3in)/2 = 48in
Now, the options are given in:
"squere inches per inch"
This is written as:
in^2/in = in.
Then we can write our above rate as:
r = 48in = 48in^2/in = 48 square inches per inch.
Answer:
Just did the test, 48 square inches is correct on edge

Often we need to use exponents to correctly model the variation in situations:
The volume of a cylinder varies jointly with the square of its radius and its height. Its
general equation looks like V = kr’h where k= some constant number for all cylinders
and V, rand h are variables representing volume, radius and height, respectively. When
the radius is 3 cm and height is 5 cm, the cylinder has a volume of 141.3 cm. Find the
volume when the radius is 6 cm and the height is 10 cm.
Answer:
V = 1130.4 cm³
Step-by-step explanation:
Given that V varies jointly with r² and h then the equation relating them is
V = kr²h ← k is the constant of variation
To find k use the condition when r = 3 and h = 5 then V = 141.3 , then
141.3 = k × 3² × 5 = 45k ( divide both sides by 45 )
k = 3.14 ← note approximation for π
V = 3.14r²h ← equation of variation
When r = 6 and h = 10, then
V = 3.14 × 6² × 10 = 3.14 × 36 × 10 = 1130.4 cm³
