3. Physics students were modeling the height of a ball once it was dropped from the roof of a 25 story
building. The students found that the height in feet, h, of the ball above the ground as a function of the
number of seconds, i, since it was dropped was given by h(t)= 300 - 1612.
From what height was the ball dropped?
To the nearest tenth of a second, determine the time at
which the ball hits the ground. Provide evidence from a
table to support your answer or solve this algebraically
if you recall how to.

Answers

Answer 1

It will take 4.3 seconds for the ball to hit the ground

Given the eqation of the height at which the object dropped expressed as

h(t) = 300 - 16t²

The object will hit the ground at when h(t) = 0

Substitute h(t) = 0 into the expression to have;

0 = 300 - 16t²

16t² = 300

t² = 300/16

t² = 18.75

t = 4.33sec

This shows that it will take 4.3 seconds for the ball to hit the ground

Evaluate: [(1/2)^2-(1/4)^3]​

Answers

Answer:

15/64

Step-by-step explanation:

Evaluate:

[(1/2)²-(1/4)³]

We have to find the value of expression ?

Explanation:-

Given that

[(1/2)²-(1/4)³]

⇛ [{(1/2)×(1/2)}-{(1/4)×(1/4)×(1/4)}]

⇛ [{(1×1)/(2×2)}-{(1×1×1)/(4×4×4)}]

⇛ [(1/4)-(1/64)]

LCM of 4 and 64 = 64

⇛ [(1×16)-(1×1)]/64

⇛ (16-1)/64

⇛ 15/64

The value of the given expression is 15/64.

Explain step by step of how you would find the scale factor for the following problem.

Answers

Answer:

Scale factor = 2.5.

Step-by-step explanation:

Work out the lengths of the corresponding sides.

The scale factor is the ratio of one side to the other.

Take the smallest length in both triangles.

Blue triangle:

length = √((7.5-2.5)^2 + (12.5-5)^2) = 9.0139 units.

Red triangle:

length = √((3-1)^2 + (5-2)^2) =3.6056

So the scale factor

= 9.0139/ 3.6056

= 2.5.

6. What is an equation in slope-intercept form for the line that passes through the points and (3, 1)? y= 3x + 1 y=x-3 y=2x + 5 y= 2x - 5​

Answers

Answer:

The correct answer is D) y = 2x - 5

To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.

m(slope) = (y2 - y1)/(x2 - x1)

m = (1 - -3)/(3 - 1)

m = 4/2

m = 2

Now that we have the slope, we can use it along with either point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 1 = 2(x - 3)

y - 1 = 2x - 6

y = 2x - 5

Answer: y=2x-5

the points are 4 points away from each other vertically, and 2 away horizontally. This makes the slope 4/2 or just 2.

take the slope and go backwards until you hit the y axis and the y-intercept is -5

this means the equation is y=2x-5

if ab=12 and a^2+b^2=25 ,then what is (a+b)^2=​

Answers

Answer:

I think it’s a^2+2ab+b^2

Answer:

49

Step-by-step explanation:

Multiply out (a+b)^2

(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba + b^2 ; not ab = ba so,

= a^2 + 2ab + b^2 = a^2 + b^2 + 2ab ; now subtitue in given values

=25 + 2(12) = 25 + 24 = 49

So (a+b)^2 = 49
