Answer:

  B)  3.2%

Step-by-step explanation:

The future value is given by ...

  A = P(1 +r)^t

Filling in the given information, we can solve for r.

  4097.01 = 3500(1 +r)^5

  4097.01/3500 = (1 +r)^5 . . . . divide by 3500

  (4097.01/3500)^(1/5) = 1 +r . . . . take the 5th root

  (4087.01/3500)^(1/5) -1 = r ≈ 0.032 = 3.2%

The annual interest rate on this account is 3.2%.

Answer:

x = 1/2 y = -1/3

Step-by-step explanation:

Split it into 2 equations:

10x-9y=8

and

21y+15x=0.5

10x - 9y = 8

Step 1: Divide both sides by 10:

x = (8+9y)/(10)

Substitute x = (8+9y)/(10) into 21y+15x=0.5 :

21y + (3(8+9))/(2) = 0.5

Solve for y

y= -1/3

Substitute y= -1/3 into x = (8+9y)/(10)

x = 1/2

Answer:

The answers were correct

Step-by-step explanation:

Answer:

A rational number can expressed as a whole number, integer, square root, fraction, and more as long as it's not imaginary. However, the number has to be clean like 1/2=0.5, 1/3=0.333, -1, 200. If it is a number that goes on forever and is not repeated like 1.22222, then it's an irrational number like pie-3.14159..., 5/0, 2.201845. If you have an imaginary number- 6i, then this would be considered as non real numbers like x+2, red, wind, and y/7.

Answer:

How many potatoes has he already pealed and what rate is he moving at

Step-by-step explanation:

Answer:

m = 15

Step-by-step explanation:

Since ∆ABC ~ ∆QRS, this implies that the ratio of their corresponding side lengths are equal. Thus:

QR/AB = QS/AC

QR = m

AB = 10

QS = 9

AC = 6

Plug in the values

m/10 = 9/6

m/10 = 3/2

Cross multiply

2*m = 3*10

2m = 30

m = 30/2

m = 15

Answer:

2/3

Step-by-step explanation:

REmember that the slope of a line is y/x. To find this, we must use the formula:

y2-y1/x2-x1=y/x

So this is -1 - -7/4- -5. The  -1 -- 7 is actually -1+7. This is 6, meaning y equals 6.

The x is 4 - - 5 is actually 4+5. This is 9, meaning x is equal to 9.

We can now write this as y/x. This would be 6/9.

Once we simplfy this, we get 2/3.

Answer:

2/3

Formula to help you get the answer:

(x - h)² + (y - k)² = r²

Answer:

The intensity of the 1906 earthquake was about 32 times the intensity of the 1995 earthquake.

Step-by-step explanation:

The earthquake with a magnitude of 8.8 is 178 times stronger than the earthquake that measured 7.3.

A logarithm is the power to which a number must be raised in order to get some other number.

Given that, there are two earthquakes of magnitude 8.8 and 7.3

The energy released is given by:

[tex]log_{10} E = 4.4+1.5M[/tex]

For 8.8

E1 = 3.981071705534X10^17

For 7.3

E2 = 2.238721138568X10^15

E1/E2 = 3.981071705534X10^17/2.238721138568X10^15 ≈ 178

Hence, The earthquake with a magnitude of 8.8 is 178 times stronger than the earthquake that measured 7.3.

Step-by-step explanation:

Answer:

Mid point = (–1 , –1)

Step-by-step explanation:

From the question given above, the following data were obtained:

(1, –6)

(–3, 4)

x₁ = 1

x₂ = –3

y₁ = –6

y₂ = 4

Mid point = (X, Y)

X = (x₁ + x₂)/2

X = (1 + –3)/2

X = (1 – 3)/2

X = –2/2

X = –1

Y = (y₁ + y₂)/2

Y = (–6 + 4)/2

Y = –2/2

Y = –1

Mid point = (X, Y)

Mid point = (–1 , –1)

Answer:

Step-by-step explanation:

hi

f(x) = (x+9)  (x-4)

if it's cross the  x axis it's means  f(x) = 0

(x+9) (x-4) = 0  means   x+9 = 0  so x = -9  and   x-4 = 0 so x = 4

answers f(x) = 0 for  x = -9 and  x = 4
