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

A) x+9 =45

x=45 - 9

x=36 cost the tickets

B) 36 :3=12 $cost a ticket

Answer:

the answer is -6

Step-by-step explanation:

x^2+36=0

x^2= -36

√x^2 = √-36

x= -6

Answer: 26!!

Step-by-step explanation: the average is like the mean which is all 4 numbers added together divided by 4. 26 times 4 is 104. 20 +42+16  = 78. 104 - 78 is 26 so the 4th number is 26. you can check the work by adding 20 42 16 and 26 together which equals 104. 104 divided by 4 is 26!! so our answer is correct!!

Answer:

16 will be added.

Step-by-step explanation:

Given equation is,

x² - 8x = 10

To convert this equation into a square form we will follow the following steps,

Step (1). x² - 2(4x) = 10

Step (2). x² -2(x)(4) + 16 = 10 + 16

Step (3). x² - 2(4)(x) + 4² = 26

Step (4). (x - 4)² = 26

In step (2) we have added 16 to both the sides of the equation to make is a perfect square.

Kindly check explanation

Step-by-step explanation:

Given the following :

Number of white balls = 5

Number of red balls = 4

Number if blue balls = 3

Probability = required outcome / Total possible outcomes

Total possible outcomes (Total number of balls) = 5 + 4 + 3 = 12

a. What is the probability that exactly two of the balls are white?

(White, white, not white) or (not white, white, white) or (white, not white, white)

Assume balls were picked without replacement ;

P(white, white, not white) = (5/12 × 4/11 × 7/10) = 0.1060606

P(not white, white, white) = (7/12 × 5/11 × 4/10) = 0.1060606

P(white, not white, white) = (5/12 × 7/11 × 4/10) = 0.1060606

P(exactly 2 white balls) = 3×(0.1060606) = 0.3181818

b. What is the probability that one ball of each color is selected ?

(White, red, blue) or (red, white, blue) or (red, blue, white) or (blue, red, white), (white, blue, red), (blue, white, red)

P(white, red, blue) = (5/12 * 4/11 * 3/10) = 0.0454545

(0.0454545 × 3) = 0.272727

c. What is the probability that all three of the selected balls have the same color ?

P(white, white, white) or P(blue, blue, blue) or P(red, red, red)

P(white, white, white) = (5/12 * 4/11 * 3/10) = 0.0454545

P(blue, blue, blue) = (3/12 * 2/11 * 1/10) = 0.0045454

P(red, red, red) = (4/12 * 3/11 * 2/10) = 0.0181818

(0.0454545 + 0.0045454 + 0.0181818) = 0.0681817

Answer:

D

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

First find the number that have their own cell phone

1/4 * 40 = 10

There are 10 students with their own cell phone

1/2  of the 10 can use social media

1/2 * 10  =5

5 have their own cell phone and can use social media

Answer: 10 students have a cell phone and only 5 of them can use social media

Step-by-step explanation: We see there are 40 students in total and 1/4 OF the class have their own cell phone. The OF means multiplacation so we do 40 X 1/4 which is 10 students who have their cellphone. We then again see 1/2 OF the 10 students can use social media meaning we do 10 X 1/2 which is equal to 5 students out of the 10 can use social media.

=======================================================

Explanation:

The given ordered pair is (4, ___) so we have x = 4 here.

We will plug this into f(x) and g(x) to get

f(4) = 6

g(4) = 7

So we have [tex]\frac{f(4)}{g(4)} = \frac{6}{7}[/tex]

-----------

If you're curious where f(4) = 6 came from, all we're doing is looking through the set of points

f = {(0, 1), (2, 4), (4, 6), (6, 8)}

to see which has 4 listed first as the x coordinate. That point is (4,6) so x = 4 leads to y = 6, ie, f(x) = 6 when x = 4. A similar situation happens with g(x) as well.

Answer:

False

Step-by-step explanation:

We know that this statement is false because a positive number times a negative number will produce a negative answer.

Answer:

False

Step-by-step explanation:

You will get a positive number only by multiplying two positive numbers or two negative numbers.

x = 36

2x + 27 = 3x - 9

27 + 9 = 3x - 2x

Step-by-step explanation:

Just add 6 to 12 or 6 x 3

6th, 12th and 18th are the first 3 days that he will do both on the same day.

A number system is defined as a system of writing to express numbers

Given that Chris is going to play baseball every 2 days and he is going to play soccer every 3 days.

We need to find the three days that he will do  both on the same day

To find this we need to find the common multiples between 2 and 3.

The multiples of 2 are 4, 6, 8, 10,12, 14, 16, 18..

The multiples of 3 are 6, 9, 12, 15, 18...

Let us take first three common multiples of 2 and 3

Which are 6, 12 and 18

Hence, 6th, 12th and 18th are the first 3 days that he will do both on the same day.

Step-by-step explanation:

Answer:

Solution: cot(52°)

Step-by-step explanation:

Remember that the cofunction of angle theta say, is the trigonometric complement of the angle. It represents the relationship between trigonometric functions. In this case you can use the formula:

tan(θ) = cot(90° - θ)

If we plug in '38 degrees' in replacement of 'theta' we can solve for tan(38) in terms of cot. Let's see what our solution is:

tan(38°) = cot(90° - 38°),

tan(38°) = cot(52°)

Therefore the cofunction with the same value as tan(38°) would be cot(52°). Remember this is only one example of it's 'cofunction.'

Answer:

cot(52)

Step-by-step explanation:

cofunction of tan (38)

The cofunction of and angle Ф is the trigonometric complement of an angle.

it shows the relationship between trigonometric  functions as:

list the cofunction formula for tan

tan(Ф) = cot(90° - Ф)

plugin Ф = 38 into the formula:

tan (38) = cot(cot(90° - 38)

tan(38 = cot(52)
