Write An Exponential Growth Function To Model Each Situation, 15. Initial Value: 20 Growth Factor: 1.25

Answers

Answer 1

Answer: f(x)=20(1.0125)^t

Step-by-step explanation:

use the formula P(1+r)^t when considering exponential growth (make it 1-r if decay)

P - principal (initial) value

r - growth rate (as a decimal! so divide by 100)

t - time (can be years, months, days, etc)

so now that we know the formula, just plug in everything you know!

P=20, r=0.0125, t=x

so the function is

20(1+0.0125)^t or 20(1.0125)^t

since we dont have a defined time, that becomes the variable for x, the one we can manipulate, so if they ask for 10 years, just replace t with 10!

Answers

Answer: Which best explains why the slope of the line between points A and D is the same as the slope between points A and B? Points A, D, and B are on the hypotenuses of similar triangles. Therefore, AD = AB, so the slope of AD is the same as the slope of AB.

A groundskeeper needs grass seed to cover a circular field, 290 feet in diameter. One pound of grass seed covers about 400​ square feet of field.

How many pounds of grass seed should the groundskeeper buy to cover the circular field?

-EXPLAIN YOUR RESONING-

Answers

Answer:165.13 pounds of grass seed.

Step-by-step explanation: to find the area of a circle you must do the equation pi r^2, so in this case that is pi*145, because radius is half the diameter, and that gets you approximately 66051.99 ft^2. when you divide 400 by this number, you get approximately 165.13 pounds of seed.

An object has a mass of 17 grams.

What is its weight in ounces?

Use 1 ounce=28.35 gram to write the conversion facto

Answers

0.6 oz would be objects weight in ounces

Step-by-step explanation:

In order to determine the weight of an object in ounces, we need to convert its mass from grams to ounces using the conversion factor of 1 ounce = 28.35 grams. Since the mass of the object is 17 grams, we can use the conversion factor to calculate its weight in ounces as follows:

17 grams * (1 ounce / 28.35 grams) = 0.6 ounces

Therefore, the weight of the object in ounces is 0.6 ounces. The conversion factor used in this calculation is 1 ounce = 28.35 grams.
