Answer:

Step-by-step explanation:

they are alternative exterior angles meaning they are equal.so you can solve by doing

7x-40=5x+10

isolate the terms by adding like terms. ( add 40 from the left side of the equation to the right.)

so it would look like this.

7x=5x+10+40. (the 40 was negative on the left side so you have to do the inverse to move it) do the same with the 5x.

now you have

2x=50. divide 50 by 2 to get your final answer .

Its parallel so they are equal
7x-40=5x+10
2x=50
x=25

___ is when the base of the exponential expression is between 0 and 1

maw [93]

Sounds like "exponential decay" is the answer your teacher is looking for

Expressions of the form y = a*b^x are considered decay equations or exponential decay equations if 0 < b < 1. So b can be between 0 and 1, but not equal to either endpoint.

Example: y = 3*0.5^x means we start off with 3 as the initial value, and then cut it in half repeatedly as x increases by 1 (eg: x = 0, x = 1, etc). This graph goes downhill as you read it from left to right.

What is the curved surface area of a cylinder with the circumference of 4 and height of 6

Vera_Pavlovna [14]

The curved surface area of a cylinder is 24cm²

Given the following data;

Base circumference = 4 cm

Height = 6 cm

<h3>How to find the curved surface area of a cylinder?</h3>

Suppose that:

Radius of the considered cylinder = 'r' units

Height of the considered cylinder = 'h' units

Then, the curved surface area of that cylinder is 2πr h

To find the curved surface area (CSA) of the cylinder we have;

CSA of a cylinder = 2πrh

But 2πr = 4 cm

Now Substituting the values into the equation, we have,

CSA of a cylinder = 6 x 4

CSA of a cylinder = 24 cm²

Hence, The curved surface area of a cylinder is 24cm²

Find all the real square roots of a. .0064 and b. -.0081

nirvana33 [79]

Answers: 0.08 and -0.08; 0.09i and -0.09i.

When taking square roots, we take the positive and negative answers. This gives us the first answer.

For the second answer, we rewrite -0.0081 as a complex number:
$\sqrt{-0.0081}=\sqrt{0.0081i^2}=i\sqrt{0.0081}=\pm0.09i$
