Answer:
The ball reaches 44 ft above the ground after 4 sec.
Step-by-step explanation:
Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t. Indicate exponentiation with " ^ "
-16t^2 + 300 = 44 becomes
-16t^2 + 256 = 0, or 16t^2 = 256. Then, taking the square root of both sides, we get:
4t = 16, or t = 4 sec. The ball reaches 44 ft above the ground after 4 sec.
The ball will take 4 seconds.
What are quadratic equations?A quadratic equation, or simply "quadratics," is a polynomial equation with a degree of two as its highest. This is how it is expressed:
a x² + b x + c = 0 where x is the unknown variable and the constant terms are a, b, and c.
Given equation of height h(t) = -16t² + 300...…..(1)
where h is height in feet and t is time in seconds,
and height at t = 0 is 300 feet
when ball is 44 feet above ground then time is,
put h = 44 in equation 1
44 = -16t² + 300
16t² = 300 - 44
t² = 256/16
t = √16
t = 4
Hence time taken by ball is 4 seconds.

If the surface area of a sphere is 484π, what is the radius?
Answer:
6.21 is the radius I believe
Step-by-step explanation:
Answer:
It would be 11.
Step-by-step explanation:
The equation for the surface area of a sphere is 4πr^2, so lets reduce the answer to get the value of r, the radius.
484π = 4πr^2
Divide by π
484 = 4r^2
Divide by 4
121 = r^2
Lastly, square root each side
11 = r
r is 11.

16. The hood of Olivia's car is the shape of a trapezoid. The base bordering the
windshield measures 30 inches and the base at the front of the car measures
24 inches. What is the width of the median of the hood?
F. 25 in.
G. 27 in.
H. 28 in.
J. 29 in.
Answer:
Option G: 27 inches.
Step-by-step explanation:
When we have a trapezoid with bases:
B₁ and B₂, the median of the trapezoid can be calculated as:
M = (B₁ + B₂)/2
In this case, we know that the bases are:
B₁ = 30 in
B₂ = 24 in
Then the median is:
M = (30in + 24in)/2 = 54in/2 = 27in
The correct option is G.

Write your answer as a fraction or whole number.
Answer:
1/6
Step-by-step explanation:
Firstly, Pr(e) = n(e)/Total outcome
Pr(2) = 1/3
Pr(1) = 1/2
Pr(1 and 2) = 1/3 * 1/2 = 1/6
owen follows the rule divide by 2 to write the pattern below. he will write two more numbers to complete the pattern. which statement is true?
Answer:
Every number in the pattern will have a 0 or a 5 in its ones place
Step-by-step explanation:
Given
Rule: Divide by 2
[tex]800, 400, 200, 100, [\ ], [\ ][/tex]
See attachment for complete question
Required
Which statement is true
First, we apply the rule to complete the blanks.
Divide by 2 implies that we divide the current element by 2, to get the next
So, the first blank becomes
[tex][\ ] = \frac{100}{2} = 50[/tex]
The next is:
[tex][\ ] = \frac{50}{2} = 25[/tex]
So, we have:
[tex]800, 400, 200, 100, 50, 25[/tex]
Compare each option with the above dataset, we have:
(a) False; because 25 do not have 0 in its 1's space
(b) False; because 50 and 25 do not have 0 in their 10's space
(c) True; because each of the dataset either have 0 or 5 in their 1's space

3x+2y=12 2x-3y=21 elimination please solve with answer and steps
Answer:
(6,-3)
or
x=6 y= -3
Step-by-step explanation:
Taking a quick look at this question we notice that we simply cannot add/subtract the two equations and eliminate a variable
What we can do is mulitply an equation to make the above true
let's try to get the first equation to have a 3y, and we can do this by multiplying it by 1.5 (this is legal because we do it to both sides)
So our new first equation is
1.5(3x+2y)=12*1.5
which simplifies to
4.5x+3y=18
We then add the two equatiosn
(4.5x+3y)+(2x-3y)=18+21
6.5x=39
x=6
Now that we know x we can plug that in and solve for y
3(6)+2y=12
18+2y=12
-6=2y
y= -3
