Step-by-step explanation:

you have the formula and the numbers. just calculate !

cost of membership

y = 100 - 0.02x

for x = 2600

y = 100 - 0.02×2600 = 100 - 52 = $48

the reduction element of the cost of membership is the

"- 0.02x" part.

we want to refuse the membership costs by $41, so

0.02x = 41

x = 41/0.02 = $2,050

the same as b)

just now the membership costs need to be reduced to 0.

so, that means we need to reduce by $100 !

0.02x = 100

x = 100/0.02 = $5,000

<h3>Answer: 7.1</h3>

=========================================================

Explanation:

The two points are (x1,y1) = (1,3) and (x2,y2) = (8,4)

Use the distance formula to get,

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-8)^2 + (3-4)^2}\\\\d = \sqrt{(-7)^2 + (-1)^2}\\\\d = \sqrt{49 + 1}\\\\d = \sqrt{50}\\\\d = \sqrt{25*2}\\\\d = \sqrt{25}*\sqrt{2}\\\\d = 5\sqrt{2}\\\\d \approx 7.0710678\\\\d \approx 7.1$

Alternatively, you can plot the two points A(1,3) and B(8,4) on the same xy grid. Then plot point C(8,3). Note that C has the same x coordinate as B, and the same y coordinate as A. Triangle ABC is a right triangle, where the 90 degree angle is at point C. The distance from A to B is the same as finding the length of AB, which is the hypotenuse.

This means we can apply the pythagorean theorem to find the hypotenuse AB. The distance formula is a modified version of the pythagorean theorem. Refer to the diagram below.

alisha [4.7K]

Answer:

b = $\frac{1}{5}$

Step-by-step explanation:

35b = 7

Divide both sides by 35.

$b = \frac{7}{35}$

Reduce the fraction $\frac{7}{35}$ to the lowest terms by extracting and canceling out 7.

$b = \frac{1}{5}$

Hope it helps and have a great day! =D

A radioactive substance decays exponentially. A scientist begins with 190 milligrams of a radioactive substance. After 19 hours,

Lelu [443]

Answer:

51 milligrams

Step-by-step explanation:

Exponential growth or decay can be modeled by the equation ...

y = a·b^(x/c)

where 'a' is the initial value, 'b' is the "growth factor", and 'c' is the time period over which that growth factor applies. The time period units for 'c' and x need to be the same.

In this problem, we're told the initial value is a = 190 mg, and the value decays to 95 mg in 19 hours. This tells us the "growth factor" is ...

b = 95/190 = 1/2

c = 19 hours

Then, for x in hours the remaining amount can be modeled by ...

y = 190·(1/2)^(x/19)

After 36 hours, we have x=36, so the remaining amount is ...

y = 190·(1/2)^(36/19) ≈ 51.095 . . . . milligrams

About 51 mg will remain after 36 hours.
