A ball is projected upward from ground level. After t seconds, it’s height in feet is a function defined by f (t) = -16t^2 + 96t. In how many seconds will the rocket be at a height of 128 ft above the ground?

Answers

Answer:

t = 2 s and t = 4 s

Step-by-step explanation:

A ball is projected upward from ground level. After t seconds, it’s height in feet is a function defined by,

[tex]f (t) = -16t^2 + 96t[/tex]

We need to find in how many seconds will the rocket be at a height of 128 ft above the ground.

It means,

[tex]128= -16t^2 + 96t\\\\-16t^2+96t-128=0\\\\16(-t^2+6t-8)=0\\\\(-t^2+6t-8)=0\\\\-t^2+4t+2t-8=0\\\\t(-t+4)-2(-t+4)=0\\\\(t-2)=0\ and\ (-t+4)=0\\\\t=2\ and\ t=4[/tex]

So, it will be at a height of 128 feet at 2 second and 4 second.

A model airplane is shot up from a platform 1 foot above the ground with an initial upward velocity of 56 feet per second. The height of the airplane above ground after t seconds is given by the equation h=-16t^2+56t+1 where h is the height of the airplane in feet and t is the time in seconds after it is launched. Approximately how long does it take the airplane to reach its maximum height?
A)0.3 seconds
B)1.8 seconds
C)3.5 seconds
D)6.9 seconds

Explanation:

Lines of symmetry; A line that cuts a shape exactly in half

If you were to put a line of symmetry down and fold the shape in half on that line, both halves would match exactly.

If you were to put a line of symmetry down on this triangle both sides would not match, therefore there are no lines of symmetry.There are zero lines of symmetry, therefore your answer is [A] 0

Answers

Answer:

Step-by-step explanation:

Add '-2a' to each side of the equation.

5a + -2a = -6 + 2a + -2a

Combine like terms: 5a + -2a = 3a

3a = -6 + 2a + -2a

Combine like terms: 2a + -2a = 0

3a = -6 + 0

3a = -6

Divide each side by '3'.

a = -2

Simplifying

a = -2

5a -2a -6

The difference in the price of 2 backpacks is $19.30. If one backpack costs $39.00, which of the answer choices could represent the price of the other backpack?

Answers

Answer:

$19.70 OR $58.30

Step-by-step explanation:

I say either or because I can't see the answer choices.

Its either adding or subtracting from the one backpack we know is $39.00

If we know the difference between the two is 19.30

39.00+19.30 = 58.30

39.00-19.30= 19.70

See if either of those are available :) Hope this helps! :)

Name the slope and y-intercept of the graph of 3x - 2y = 18 A. B. 2 3 -6 6 C. -3.-9 D. 2 -9​

Answers

Answer:

D. 3/2, -9

Step-by-step explanation:

First, rearrange the equation 3x - 2y = 18 into the slope-intercept form of y = mx + b:

3x - 2y = 18

2y = 3x - 18

y = 3x/2 - 9

from this, u can tell that the slope is 3/2 and the y-intercept is -9 (option D)

Paul invests £150 in a bank account paying 2% interest per annum for 10 years. Work out how much money he has in the account at the end of the 10 years

Answers

Answer: £180

Step-by-step explanation:

The interest gotten for the 10 years will be calculated as:

= Principal × Rate × Time

= 150 × 2% × 10

= 150 × 0.02 × 10

= 30

The amount he has in the bank account at the end of the 10 year will be:

= Principal + Interest

= £150 + £30

= £180

10 meaning the biggest number and then subtract by 4 since it’s the lowest number and you get 6.

Answer:

10-4=6

Step-by-step explanation:

The range is the difference between the biggest and smallest number. In this case, 10 is the biggest number and 4 is the smallest. So we do 10-4, which gives us 6, so 6 is the range.

A lot runs between two parallel streets. The length of the lot on one of the streets is 160-ft. The length of the lot on the other street is 100-ft. The area of the lot is 14,170 square feet. How far apart are the two streets?

Answers

Answer:

Step-by-step explanation:Area = 1/2(b1 + b2)x h

Area = 18,000 ft^2

b1 = 80 ft

b2 = 100 ft

18,000 = 1/2(80 + 100) x h

36,000 = (180)h

h = 36,000/180

h = 200ft.

This is the distance between streets.

Hope this helps :-)Area = 1/2(b1 + b2)x h

Area = 18,000 ft^2

b1 = 80 ft

b2 = 100 ft

18,000 = 1/2(80 + 100) x h

36,000 = (180)h

h = 36,000/180

h = 200ft.

This is the distance between streets.

Y=4-2x 3y-2x=4 solve using substitution

Answers

Answer:

x=1 y=2

Step-by-step explanation:

y=4-2x             3y=4+2x

3*(4-2x)=4+2x

12-6x=4+2x

12-4=2x+6x

8x=8

x=1

y=4-2*1

y=2

First turn the equation y=4-2x into a y=Mx+b formula. It would be y=-2x+4. Then plug it in into the y on the second equation. I’d be 3(-2x+4)-2x=4. Then solve. The answer is x=1. Hope it helped. :)

A cinema has 300 seats. 60% are filled. How many are empty? i will give brainliest

Answers

180 are empty
............

Answer:

120 seats

Step-by-step explanation:

Total seats in the hall = 300

Percentage of filled seats = 60 %

Number of seats filled = (60 / 100) 300

                                     = 60 * 3

                                     = 180

Therefore, number of empty seats = 300 - 180

                                                          = 120
