Find the equation of the line. Use exact numbers y=, x,+5

Answers

I can't see pictures, so I'll do my best.

y= always stays the same.

To find the slope, or x, you have to start at the y-intercept, and find the number of units up, then right.

For example, y=4/3+6

4/3 is the slope because it goes up 4 units and right 3 units from the y-intercept.

6 is the y-intercept, which is the y-coordinate. It can also be graphed as (0,6).

Keegan deposited $550 in savings account that pays 6.5% annual interest compounded quarterly write the compound interest formula to represent keegan's investment after 5 years how much money would Keegan have in the account after 5 years

Answers

Answer:

A = $759.23 after 5 years

Step-by-step explanation:

The compound interest formula applicable here is

A = P(1 + r/n)^(nt), where n is the number of compounding periods per year.

Here P = $550, r = 0.065, n = 4 and t = 5.

We get A = $550(1 + 0.065/4)^(4*5), or

             A = $550(1 + 0.01625)^20, or:

              A = $759.23

B. –1

C. 1

D. [tex]-\frac{3}{8}[/tex]

Answers

Answer:

B. -1

Step-by-step explanation:

-1

According to the slope formula:

Slope = (y2 - y1)/(x2 - x1)

y2 = 6.1

y1 = 3.1

x2 = -5.5

x1 = -2.5

Therefore:

6.1-3.1/-5.5--2.5

Since negative negative is positive you are left with:

3/-3

Therefore the answer is -1.


The speed, v, of a wave is inversely proportional to the square root of the
depth, d, of the water. When v= 30 then d = 400.
Find y when d=25.

Answers

Answer:

v = 120

Step-by-step explanation:

If v is inversely proportional to square root of d, then we can write

[tex]v \sqrt{d}[/tex] = k    

If v  = 30 and d = 400, then

30([tex]\sqrt{400}[/tex]) = k

k = 30(20) = 600

Now [tex]v \sqrt{d}[/tex] = 600

If d = 25, then v[tex]\sqrt{25}[/tex] = 600

                         5v = 600

                            v = 120

What is the area of the square?

Every one of the sides of a square is consistent. Let 'x' be the side length of the square. Then the region of the square is the square of the side length of the square.

Then the area of the square will be

Area of the square = x² square units

The expression is given below.

⇒ √24

If the area of the square is 24 square units. Then the side length is given as,

x · x = Area

x · x = 24

x² = 24

x = √24

The side length of the square with an area of 24 square units will be √24 units. Then the correct options are B and C.

Answer:

  b(t) = 36000·e^(0.12t)

Step-by-step explanation:

Continuous growth at a rate of r per time period is modeled by the exponential multiplier e^(rt), where t is the number of time periods. This value multiplies the initial amount (at t=0). In this case, the model would be ...

  b(t) = 36000·e^(0.12t)

where b(t) is the number of bacteria in the colony after t time periods.
