Trevor found that a circle has a circumference of 15 ft. What is the diameter & radius of the circle? Write & solve an equation. Leave your answer as a decimal.

Answer:

y = 2x² + 8x + 8

Step-by-step explanation:

x = t - 2 → t = x + 2

y = 2t²

Substitution:

y = 2(x + 2)²

y = 2(x² + 4x + 4)

y = 2x² + 8x + 8

Hey there!

1,000:

= 2 × 2 × 2 × 5 × 5 × 5

= 4 × 2 × 5 × 5 × 5

= 8 × 5 × 5 × 5

= 40 × 25

= 1,000

180:

= 2 × 2 × 3 × 3 × 5

= 4 × 3 × 3 × 5

= 12 × 15

= 180

LOOKING FOR THE LCM (Lowest Common Multiple)

(1,000 × 180) ÷ 20

= 180,000 ÷ 20

= 9,000

[Answer: 9,000]

Good luck on your assignment and enjoy your day!

Answer:

363 feet because the elevator travels at a speed of 33 feet per second.

Step-by-step explanation:

330ft = 10 seconds

Divide both sides by 10

33ft = 1 second

now we know that the elevator travels 33 ft per second

To find how far does the elevator travel in 11 seconds,multiply both sides by 11

33ft = 1 seconds

363ft = 11 seconds

Answer:

  (x, y) = (1, -6)

Step-by-step explanation:

The expression for y given by the first equation can be substituted into the second equation.

  11x +(-8x +2) = 5 . . . substitute for y

  3x +2 = 5 . . . . . . . simplify

  3x = 3 . . . . . . . . . subtract 2

  x = 1 . . . . . . . . . divide by 3

  y = -8×1 +2 = -6 . . . . use the first equation to find y

The solution is (x, y) = (1, -6).

Answer:

y=-5/4x+3

Step-by-step explanation:

Y-intercept is 3 so +3 and the slope is -5/4 so -5/4x.

Answer:

x+4 y-5

Step-by-step explanation:

x move over 4 y move down 5 ez

b = -0.5

4 + 2 = - 0.5 * 4 + 8

6 = -2 + 8

6 = 6

Which is true, Therefore the answer is -0.5

For b = - 0.5 , y =4 is the solution of the equation  y + 2 = by + 8.

We have the following equation → y + 2 = by + 8.

We have to find the value of b for which y = 4 is a solution to the equation → y + 2 = by + 8.

The solution of a function f(x) is the value of x for which f(x) = 0.

According to the question, we have -

y + 2 = by + 8

y - by - 6 = 0

y(1 - b) - 6 = 0

y(1 - b) = 6

1 - b = 6/y

1 - 6/y = b

b + 6/y = 1

For y = 4 ->

b + 6/4 = 1

b + 1.5 = 1

b = - 0.5

Hence, for b = - 0.5 , y =4 is the solution of the equation  y + 2 = by + 8.

Step-by-step explanation:

We have the expression "Nine more than the product of 5 times the number of tires t". Let's focus on nine more to cross out some answers, "nine more than the" indicates that there must be a certain operation to happen first before 9 is added onto it.

Answer:

y = 20 degrees.

Step-by-step explanation:

Both base angles are 25 degrees so 5x = 25 giving x = 5.

3y + 70 = 180 - 2(25) = 130

3y = 130 - 70 = 60

y = 60/3 = 20.

Answer:

y= -6x - 51

Step-by-step explanation:

5y = -6x - 10

Slope: -6

y = -6/5x - 2

Point: (-10,9)

y-intercept: 9 - (-6)(-10) = 9 -60 = - 51

$6,055.73

Step-by-step equation:

THE MAIN FORMULA:

           initial amount (rate)^the amount of times it is occuring

Step #1, we need to break up the problem for the information:

Tia invests $2,500 at an interest rate of 4%, compounded quarterly,  

and another $2,500 at an interest  rate of 3.75%, compounded  annually. How much are the  investments worth at the end of  5 years ?

Step #2, find out how much the first account has in 5 years:

so we know that the rate is 4% quarterly and a quarter is 4. You have to divide 4% (.04 in decimal form) and 4 to get how much the rate is every quarter. That would be .01. After finding how much it is quarterly you would need to add 1. because it is increasing and not decreasing.

For the 20, you would need to multiply 5 and 4. 5 is the amount of years and the 4 is how many times it is happening in that 1 year.

                                              2,500 (1.01)^20

Step #3, find out how much the second account has in 5 years:

we do the exact same steps like we did to find her first account but with different numbers.The number 20 is 5 because it only says for the second account "compounded annually" and annually means oncea year so you would have to mulitiply 5 by 1 and it would get you 5.

To find the rate, we would need to add 1 instead of subtracting one because the problem is and not decreasing. So it would be 3.75% (.0375 in decimal form) plus 1. and it would get you 1.0375.

                                            2,500 (1.0375)^5

The last step is adding the answers to both of those equations together to get the amount of money that she invested:

                              3005.25 + 3050.48= $6055.73
