Solve for v2
[tex]a \: ave = \frac{v2 - v1}{t2 - t1} [/tex]
​

Answers

Answer:

Solving the given formula for v2 gives us:

[tex]a(t_2-t_1)+v_1 = v_2[/tex]

Step-by-step explanation:

Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.

Given equation is:

[tex]a = \frac{v_2-v_1}{t_2-t_1}[/tex]

Multiplying both sides by t2-t1

[tex](t_2-t_1) . a = \frac{v_2-v_1}{t_2-t_1} . (t_2-t_1)\\a(t_2-t_1) = v_2-v_1[/tex]

Adding v1 to both sides of the equation

[tex]a(t_2-t_1)+v_1 = v_2-v_1+v_1\\a(t_2-t_1)+v_1 = v_2[/tex]

Hence,

Solving the given formula for v2 gives us:

[tex]a(t_2-t_1)+v_1 = v_2[/tex]

Mr. Florean opened an account with deposit of $5,000. The account earned 7.5% annual simple interest. He did not make any additional deposits or withdrawals. After some time, the balance of the account was $6,500. How many years did it take for mr.Flores to have a balance of $6,500?

Answers

Answer:

4 years

Step-by-step explanation:

The simple interest = $6,500 - $5,000 = $1500

From the formula for simple interest;

I=PRT/100

T= 100 I/PR

T= 100 × 1500/5000 × 7.5

T= 150000/37500

T= 4 years

18) If Holstein cows produce milk that is on average 3.66% butterfat and Jersey
cows produce milk that is on average 4.5% butterfat, how many gallons of Jersy milk
should be added to every 100 gal of Holstein milk to have milk that is 4% butterfat?

Guys please help me with this question I’m using all my points for this please just help me

Answers

Answer:

68 gallons

Step-by-step explanation:

Milk of Holstein cows ⇒ 3.66% butterfatMilk of Jersey  cows ⇒ 4.5% butterfat

If we add x gal of 4.5% milk, then we have below equation:

100*0.0366 + x*0.045 = (100 + x)*0.043.66 + 0.045x = 0.04x + 40.045x - 0.04x = 4 - 3.660.005x = 0.34x = 0.34/0.005x = 68 gal

Answer:

y=35 x=145

Step-by-step explanation:

y is equivalent to 35

180-35=145

Answer:

x = 145

y = 35

Step-by-step explanation:

x and the 35 degree angle are supplementary angles, so x + 35 = 180.

solve for x, x = 145. the 35-degree angle and angle Y are corresponding angles, so the value of y will be 35.

Answers

Answer:

4600

Step-by-step explanation:

Can you give me the answers from 1 to 6 and tell me how you get the answers please

Answers

Answer:

1. Y = 2, 1, 4, 7, 10

2. Y = -12, -8, -4, 0, 4

3. Y = -7, -5, -3, -1, 1

Step-by-step explanation:

all of the numbers in the x value you just substitute in the x place in problem

1. Y = 3x + 4

x: -2, -1, 0, 1, 2

Y = 3(-2) + 4

Y = -6 + 4

Y = -2

You then have:

x: -2, -1, 0, 1, 2

y: -2,

Y = 3(-1) + 4

Y = -3 + 4

Y = 1

You then have:

x: -2, -1, 0, 1, 2

y: -2, 1

just continue substituting each x variable into the x place to get your y variable.

How many 5-digit personal identification numbers are possible if the number cannot contain a
zero?

Answers

Answer:

59049 digits

Step-by-step explanation:

Given

Digits = 0 to 9

Required

Determine number of 5 digit pins that must not contain 0

There are 10 digits.

Since the pin must not contain 0, there are 9 digits left to select from.

The question didn't state that a digit can not be repeated, so I'll assume that repetition of digit is allowed.

The 1st digit of the 5 could be any of the 9 digits

The 2nd could be any of the 9 digits

The 3rd could be any of the 9 digits

The 4th could be any of the 9 digits

The 5th could be any of the 9 digits

Hence, number of selection is calculated as this:

Selection = 9 * 9 * 9 * 9 * 9

Selection = 59049
