Answer:
t = 8.69 s
Step-by-step explanation:
The height h of the rocket in feet above the surface of the lake can be modeled by :
[tex]h=340+100t-16t^2[/tex]
Let we need to find the time to reach the ground. When it reach the ground, h = 0
[tex]340+100t-16t^2=0[/tex]
We need to find the value of t.
t = 8.69 s and -2.45 s
Neglecting negative value,
t = 8.69 s
Hence, it will take 8.69 s to reach the ground.

ANSWER ASAP PLZ Which expression is equivalent to 24 + 64?
8(3 + 64)
8(16 + 56)
8(3 + 8)
8(16 + 64)
Answer:
8(3+8)
Step-by-step explanation:
24+64=88
Now you have to find which expression equals 88.
8(3+64)=8x3+8x64=24+512=536
8(16+56)=8x16+8x56=128+448=576
8(3+8)=8x3+8x8=24+64=88
Therefore, 8(3+8) is correct.

Answer:
x = 10
Step-by-step explanation:
The two triangles are similar, and it says that VUT is similar to EFG so side VT corresponds to side EG which means that 8 is just side VU divided by 2.
This means that side EG is 14 divided by 2 and that is 7.
This results in the equation " 2x - 13 = 7" First, add 13 to both sides of the equation to get rid of the -13. This gives 2x = 20. Then divide both sides by two to cancel out and get rid of the 2 in 2x. This leaves x as 10.
5. What is the perimeter of a rectangle with a length of 9x - 4 and a width of 5x+2?
Answer:
14x-2
Step-by-step explanation:
In order to find the perimeter we need to add the length and width together. So adding 5x and 9x gives us 14x. -4+2=-2
The perimeter of a rectangle with a length of 9x - 4 and a width of 5x+2 is, 28x-4
What is the perimeter?Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.
Perimeter = Sum of length of the all the sides
Given that,
length of rectangle = 9x - 4
width of rectangle = 5x+2
As we know,
Perimeter = Sum of length of the all the sides
Perimeter = (9x - 4) + (5x+2) + (5x+2) + (9x - 4)
Perimeter = 28x-4
Hence, The perimeter is 28x-4

A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
[tex]h(t)=-16t^2+48t+160[/tex]
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
[tex]-16t^2+48t+160=0[/tex]
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.

The square root of the quotient of a number n and 3 is equal to the square root of 4 less than the number. Which of the following is the value of n?
Answer:
6
Step-by-step explanation: You can set up the equation: [tex]\sqrt{\frac{n}{3} }[/tex] = [tex]\sqrt{n-4}[/tex] You square both sides to cancel out the squares which leaves you with [tex]\frac{n}{3}[/tex] = n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with [tex]\sqrt{2}[/tex] on both sides.

Anna made and sold x ceramic vases one week. Her profit, P, in dollars is calculated using the formula P = R - C . Where R represents her revenue and C represents her costs. If R = 25x - 0.5x ^ 2 C = 100 + 5x which expression represents her profit in dollars?
Answer:
-0.5x² + 20x + 100
Step-by-step explanation:
Given:
R = 25x - 0.5x²
C = 100 + 5x
P = R - C
Where,
P = profits
R = Revenue
C = Cost
which expression represents her profit in dollars?
P = R - C
R = 25x - 0.5x²
C = 100 + 5x
= 25x - 0.5x² -(-100 + 5x )
= 25x - 0.5x² + 100 - 5x
= -0.5x² + 20x + 100
The expression which represents her profit in dollars is -0.5x² + 20x + 100

Hello!
Answer:[tex]\boxed{ \bf x=6}[/tex]
Explanation:3(x + 3) = 18
⇒ Step 1 - Multiply everything in the brackets by 3:
3x + 9 = 18
⇒ Step 2 - Subtract 9 from both sides of the equation:
3x + 9 = 18
- 9 - 9
3x = 18
⇒ Step 3 - Divide both sides of the equation by 3.
[tex]\frac{3x}{3} = \frac{18}{3}[/tex]
x = 6
Answer: x = 3
Step-by-step explanation:
1. Distribute.
3(x+3)=183x+9=182. Subtract 9 from BOTH sides.
3x+9-9=18-93. Simplify.
Subtract 9 from BOTH sides.3x=9 is the answer.4. Divide BOTH sides of the equation by the same term.
[tex]\frac{3x}{3} =\frac{9}{3}[/tex]5. Simplify.
Cancel out the terms that are both in the numerator and the denominator.Divide the numbers.Therefore, your answer is X = 3
Find the value of X
Answer:
should be 80, angle 50 is congruent on both sides to 50+50 equals 100. The triangle sum theorem says a triangle adds up to 180 degrees so we are left with 80, X=80 degrees
