The result of 3x²-75=0

1 answer:

7 0

3x^2 - 75 = 0

Add 75 on both sides

3x^2 = 75

Divide by 3 on both sides

x^2 = 25

Take the square root of both sides

$\boxed{x= \pm 5}$

x = 5
x = -5

9. What is the relationship between the estimates you found for the lengths of the two equators?4 grade student

Ann [662]

7. You have the equator's length of four planets, the distances are given in kilometers

8. Estimation for the Earth: 40.000 km. Jupiter: 400.000. These approximations come from the nearest whole number for each.

9. The relation is that if the Jupiter equator's length is divided by ten, you will get the Earth's equator length, which means that Jupiter's equator is ten times bigger than the earth.

The function f(x)= 3(1.4)' gives the length (in inches) of an image after being enlarged by 10% x times.

kondaur [170]

Answer:

3.99 inches

Step-by-step explanation:

<u><em>The correct question is</em></u>

The function f(x) = 3(1.1)^x gives the length (in inches) of an image after being enlarged by 10% x times.

What is the length of the image after it has been enlarged 3 times? Round your answer to the nearest hundredth

we have

$f(x)=3(1.1)^x$

This is a exponential growth function

where

f(x) represent the length (in inches) of an image

x is the number of times the image is enlarged

For x=3

substitute in the exponential equation

$f(x)=3(1.1)^3=3.99\ in$
