Answer:

2h/ t^2 - 2v/t =g

Step-by-step explanation:

h = vt+1/2 gt^2

Subtract vt from each side

h - vt = vt+1/2 gt^2 -vt

h - vt = 1/2 gt^2

Multiply each side by 2

2( h-vt) = 2 * 1/2 g t^2

2 ( h-vt) = gt^2

Divide each side by t^2

2 ( h-vt) / t^2= gt^2/t^2

2/t^2 (h -vt) = g

Distribute

2h/ t^2 - 2v/t =g

Answer: 42° and 138°
Steps: First find value of x by adding both equations and setting them equal to 180°:
3x + 12x - 30 = 180
15x - 30 = 180
15x = 210
x = 14

Next, put value of x into equations to find the angle:
3x
3(14)
42°

12x - 30
12(14) - 30
168 - 30
138°


11. Answer: 28°
Steps: Complementary angles add up to 90°, so subtract 62° from 90° to find its complementary angle.
90 - 62 = 28


12. Answer: Corresponding angles are congruent.

a. Represent the length and width of the original garden using an appropriate variable.

Width:

W.4

w

Length:

b. Using the same variable, represent the perimeter of Mr. Kim's garden after it is

enlarged

Perimeter:

Answers

Answer:

P = 10W + 28

Step-by-step explanation:

Let L be the original length of the garden

W  be the original width of the garden

If Mr. Kim's rectangular garden is four times as long as it is wide, then L = 4W

If he is going to enlarge it  by extending each side 7 feet, then;

The new length l = (4W + 7) feet

The new width will be w =(W+7) feet

Perimeter of the rectangular gerden P = 2(l+w)

l and w are the new length and width

Substituting l = 4W+7 and w = W+7 into the formula;

P = 2(4W+7+W+7)

P = 2(5W+14)

open the parenthesis

P = 10W + 28

Hence the perimeter of Mr. Kim's garden after it is  enlarged is given by the expression P = 10W + 28

Answer/Step-by-step explanation:

well, first figure out how many units/times prism A was enlarged to become prism B...

16 ÷ 2 = 8

Now if we apply that info to the length of the prism, then...

80 ÷ 8 = 10

Therefore x = 10

Step-by-step explanation:

Crude oil imports to one country from another for 2009–2013 could be approximated by the following model where t is time in years since the start of 2000. I(t) = −33t2 + 800t − 3,000 thousand barrels per day (9 ≤ t ≤ 13) According to the model, approximately when were oil imports to the country greatest?

Answers

Answer:

Import in 2012 was the greatest

Step-by-step explanation:

Given

l(t) = -33t² + 800t - 3000

9 ≤ t ≤ 13

Required

Determine the year with highest import.

To do this we simply substitute the values of t from 9 to 13 in the given function.

When t = 9

l(t) = -33t² + 800t - 3000

l(9) = -33 * 9² + 800 * 9 - 3000

l(9) = -33 * 81 + 800 * 9 - 3000

l(9) = -2673 + 7200 -3000

l(9) = 1527

When t = 10

l(10) = -33 * 10² + 800 * 10 - 3000

l(10) = -33 * 100 + 800 * 10 - 3000

l(10) = -3300 + 8000 - 3000

l(10) = 1700

When t = 11

l(11) = -33 * 11² + 800 * 11 - 3000

l(11) = -33 * 121 + 800 * 11 - 3000

l(11) = -3993 + 8800 - 3000

l(11) = 1807

When t = 12

l(12) = -33 * 12² + 800 * 12 - 3000

l(12) = -33 * 144 + 800 * 12 - 3000

l(12) = -4752 + 9600 - 3000

l(12) = 1848

When t = 13

l(13) = -33 * 13² + 800 * 13 - 3000

l(13) = -33 * 169 + 800 * 13 - 3000

l(13) = -5577 + 10400 - 3000

l(13) = 1823

Comparing the values of l(t) for the range of t = 9 to 13,

The highest value of l(t) is:

l(12) = 1848

Hence, the year with the highest import is 2012

The oil imports to the country are greatest during the year 2012

Given the model where t is time in years since the start of 2000 expressed as I(t) = −33t² + 800t − 3,000

The oil imports more oil during the year 2012, is t = 12

I(12) = −33(12)² + 800(12) − 3,000

I(12) = -33(144) + 9600 - 3000

I(12) = -4752 + 6600

I(12) = 1848

Hence the oil imports to the country are greatest during the year 2012
