Answer:

growth2.3%

Step-by-step explanation:

The number with the exponent is 1+0.023/4 = 1.00575. This number is greater than 1, so represents growth.

When x increases by 1, the multiplier of 800 increases by ...

  1.00575^4 ≈ 1.023199 = 1 + 2.3199%

Rounded to the nearest tenth percent, this is a 2.3% growth rate.

_____

Additional comment

The formula corresponds to a financial formula in which a 2.3% annual interest rate is compounded 4 times per year. The effective annual interest rate is almost 2.32% per year. The difference is there, but is too small to see when the interest rate is rounded to a tenth percent.

• Mrs. Alvarez rents skis and poles for 3 days.
What is the total cost of the rental?
• The total cost of the rental is $

Answers

The value that Mrs. Alvarez will pay depends on the rental value of the ski and the poles per day, for example $144.

How to calculate the total loan cost of Ski equipment?

To know the total cost of the loan of the Ski equipment, we must know the loan price per day or per hour.

For example, suppose the loan price per hour is $2, then we would have to calculate how much one day is equivalent to and then multiply it by the total number of days.

$2 x 24 = $48

$48 x 3 = $144

Note: This question is incomplete because some information is missing. However I can answer it based on my general prior knowledge.

Answers

Answer:

x = 10; y = 10

Step-by-step explanation:

[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]

[tex] \cos( {theta} ) = \frac{adjacent}{hypotenuse} [/tex]

[tex] \tan( {theta} ) = \frac{opposite}{adjacent} [/tex]

theta = 45°

opposite = x

hypotenuse = 10√2

adjacent = y

1) find x using sin formula

[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]

[tex] \sin(45) = \frac{x}{10 \sqrt{2} } [/tex]

[tex] \sin(45) \times 10 \sqrt{2} = x[/tex]

[tex]10 = x[/tex]

[tex]x = 10[/tex]

2) find y using cos formula

[tex] \cos( {theta} ) = \frac{adjacent}{hypotenuse} [/tex]

[tex] \cos(45) = \frac{y}{10 \sqrt{2} } [/tex]

[tex] \cos(45) \times 10 \sqrt{2} = y[/tex]

a. -4 and 4b + 4
b. 3x and 1 -3x

Answers

Answer:

Does this problem have a picture, I just need to make sure I am seeing everything correctly thanks!

Step-by-step explanation:

a. -4 and 4b + 4 = 4b

-4 and 4b + 4 = -4 + (4b + 4) = 4b + (4 - 4) = 4b + 0 = 4b

b. 3x and 1 - 3x = 1

3x and 1 - 3x = 3x + (1 - 3x) = 1 + (3x - 3x) = 1 + 0 = 1

plot the x- intercept and y- intercept. then write the intercepts as ordered pairs

Answers

Answer:

x-intercept = 4

y-intercept = -1

As ordered pairs they would be ( 4, 0) and ( 0, -1)

Step-by-step explanation:

The line goes through 4 on the x line and goes through -1 on the y line.

As an ordered pair you just put the numbers in their x and y spots being ( x, y )

With 4 being on the X and -1 being on the Y it would make them ( 4, 0) and

( 0, -1).

Hello, I really truly need help please, PLZ! Thanks!

(5 screenshots included)

Answers

Answer:

1. Second Choice

2. Positive

3. Line B

4. Line D

5. Horizontal

Step-by-step explanation:

First Screenshot

The y-intercept is the value of b —

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

Looking from the graph, the graph passes y-axis at (0,1) which is y-intercept.

Basically (0,a) is y-intercept.

Thus, our y-intercept is (0,1)

Second Screenshot

The slope is positive. If the slope is negative, it would face opposite.

For zero slope, the graph will become a horizontal line.

An undefined slope is the vertical line graph.

Third Screenshot

Line B has zero slope. As said, the zero slope will turn the graph into a horizontal line.

Fourth Screenshot

Line D has an undefined slope. Read Third Screenshot.

As said, an undefined slope is the vertical line.

Fifth Screenshot

[tex]y = - 3[/tex]

This is called Constant Function where the graph is a horizontal line. For a vertical line, it must be x = a (where a is constant)

FYI,

y = a — horizontal

x = a — vertical
