A man drops a ball from the top of a 300 foot cliff. The height of the falling ball is modeled
by h(t)=-16t2+300 where h is in feet and t is in seconds. How long does it take for the ball to be 44 feet above the ground?

Answers

Answer 1

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.

Answer 2

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.

Answers

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

Calculate the value of this

3x+2y=12 2x-3y=21 elimination please solve with answer and steps

Answers

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

16. The hood of Olivia's car is the shape of a trapezoid. The base bordering the

24 inches. What is the width of the median of the hood?

F. 25 in.

G. 27 in.

H. 28 in.

J. 29 in.

Answers

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.

I=$26.24, P=$500, T=18 months the annual interest rate is

Answers

A = $2,861.60

I = A - P = $2,361.60

Equation:
A = P(1 + rt)

Calculation:
First, converting R percent to r a decimal
r = R/100 = 26.24%/100 = 0.2624 per year.

Solving our equation:
A = 500(1 + (0.2624 × 18)) = 2861.6
A = $2,861.60

The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 26.24% per year for 18 years is $2,861.60.

If the surface area of a sphere is 484π, what is the radius?

Answers

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.
