Choose all the key words that indicate an exponential function.
A
decreases by a factor 0f .12
B
quadruples
C
increase by 100
D
decreases by 2
E
increase by a factor of 10
F
increases by 23%

A, E and F.

Step-by-step explanation:

A simple exponential function is something of the form

f(x) = a*r^x

a is the initial amount

r is the factor of increase of decrease.

x is the variable.

then any increase or decrease by a given factor can be related to a exponential function so options A and E can be related to exponential functions.

Particularly, the option F says that the increase is by 23%.

So we have that the increase is:

A to A + 0.23*A = 1.23*A

So we have a factor of 1.23, this is also an exponential function.

wriRedrawn the figure, refer to the ATTACHMENT with additional angles.

So, if we see the figure:-

Given that:-

The angles given are:-

70°

75°

65°

To find:-

The value of x.

Let's Do!

If now, you see the red angles marked byme, they are Vertically Opposite angles.

Let is find that first.

70 + 75 + y = 18070+75+y=180

145 + y = 180145+y=180

y = 180 - 145y=180−145

y = 35y=35

Now, the measure of red angle is 35°.

Now, as I said, they are Vertically opposite, so they are equal.

x + 35 + 65 = 180x+35+65=180

x + 100 = 180x+100=180

x = 180 - 100x=180−100

x = 80x=80

So, the value of x is 80°. Hence the final answer.
