16. PHYSICS The formula h = 1201 - 16t2 gives the height h in feet of an object 1 seconds after it is shot upward from

Murrr4er [49]

<h3>Question:</h3>

The formula h = 120t-16t^2 gives the height h in feet of an object t seconds after it is shot upward from Earth's surface with an initial velocity of 120 feet per second. What will the height of the object be after 6 seconds?

<h3>Answer:</h3>

The height of object after 6 seconds is 144 feet

<h3>Solution:</h3>

The formula that gives the height of an object is:

$h = 120t - 16t^2$

Where,

h is the height in feet and t is the time in seconds

To find: height of the object be after 6 seconds

To find the height of the object be after 6 seconds, substitute t = 6

$h = 120 \times 6 -16(6)^2\\\\h = 720 - 16 \times 36\\\\h = 720 - 576\\\\h = 144$

Thus height of object after 6 seconds is 144 feet

Simplify the product.

liberstina [14]

The value of the product expression is –6p^3 + 8p^2 – 10p

<h3>How to simplify the product?</h3>

The product expression is given as:

2p(–3p2 + 4p – 5)

Rewrite properly as:

2p(–3p^2 + 4p – 5)

Remove the bracket

2p * –3p^2 + 2p * 4p – 2p * 5

Evaluate the products

–6p^3 + 8p^2 – 10p

Hence, the value of the product expression is –6p^3 + 8p^2 – 10p

When solved for x, what is the sum when the roots of the quadratic equation are added?

Anna35 [415]

Answer:

A

Step-by-step explanation:

x² + 10x + 24 = 0

Here, a = 1, b = 10, c = 24. Factoring using the AC method:

ac = 1×24 = 24

Factors of 24 that add up to 10 are +4 and +6.

Therefore:

(x + 4) (x + 6) = 0

x + 4 = 0, x + 6 = 0

x = -4, x = -6

The roots are -4 and -6. Added together:

-4 + -6 = -10

Answer A.

5x + 2 = 8x + 5 Help me before I die quick math is so hardddddd

attashe74 [19]

Answer:

x = -1

Step-by-step explanation:

Note: when you send a number across it can change it sign. If it is positive it will turn negative.

5x + 2 = 8x + 5

Send 8x across

5x + 2 - 8x = 5

send 2 across

5x - 8x = 5 - 2

- 3x = 3

Divide both sides by - 3

- 3x/- 3 = 3/- 3

- 3 cancel out - 3

x = 3/ - 3

3 divided by - 3 is - 1

x = -1
