Which exponential function goes through the points (1,32) and (4,2048)

Answers

Answer:

y=8*4^x

Step-by-step explanation:

Let the exponential function be of the form y=A*B^x

We want to find constant A and B.

So I'm going to use (1,32) giving me 32=A*B

I'm going to use (4,2048) giving me 2048=A*B^4

2048/32=64

A*B^4/A*B=B^3

So If you divide the equation 2048=A*B^4 by 32=A*B

we get 64=B^3

which gives us B=4

Since 32=A*B and B=4 then A=8

So the answer is y=8*4^x

HELP twice a number plus twice a second number is 310. The difference between the numbers is 55. Find the numbers by writing and solving a system of equations. Explain how you solved the system. PLEASE HELP ME Thank you!   I got numbers are 182.5 and 127.5 but I don't understand how to set up the system equations

Answers

The numbers by writing and solving a system of equations are 50 and 105

System of equations

Let the unknown numbers be x and y

If twice a number plus twice a second number is 310, then;

2x + 2y = 310

x + y = 155

x = 155 - y

Also, If the difference of the numbers is 55, hence;

x - y = 55

155 - y - y = 55

155 - 2y = 55

-2y = 55 - 505

2y = 100

y = 50

Substitute y = 25 into 1 to have:

x = 155 - 50

x = 105

Hence the numbers by writing and solving a system of equations are 50 and 105

Twice a number plus twice a second number is 310.
2x + 2y = 310

The difference between the numbers is 55.
x-y = 55

Divide the first equation by 2 to get a 3rd equation:
x+y=155

Add the second and third equations together:
x-y=55
x+y=155
2x=210
x=105

Put x=105 into the second equation to get:
105-y=55
y=50

So you're answers are x=105 and y=50.

Answers

m<ABC = m<EBD = 36 (vertical angles)

78 - x + 36 + 3x - 10 = 180 (straight angle)

Now solve for x

78 - x + 36 + 3x - 10 = 180
2x + 68 = 180
     -  68     -68 (subtract 68 on both sides)
2x        =  58

In 2004, there were approximately 275 students in the Delaware High School band. In 2010, that number increased to 305. Find the annual rate of change in the number of students in the band.

Answers

305-275=30
Since there is a difference of 6 yaers between 2010 and 2004, you devide 30 by 6 which equals to five. Therefore each year there was an increase of 5 students in the band.

Mari makes bows for floral arrangements. She uses 1/8 of a yard ribbon for each bow. How many bows can she make from 2 spools that each has 24 yards ribbon?

Answers

First, you need to find out how much ribbon she has total. Because there are two spools, you multiply 24 x 2. The answer for that is 48. Then you have to figure out how many bows she can make. Each bow uses 1/8 of a piece of yard of ribbon, so you can divide 48 by 8. Your answer would then be 6 bows.

Here are the equations.

24*2 = X

X/8 = B

Where X represents the yards of ribbon available and B represents the number of bows that Mari can make.
