The diagram has been inserted below.

There is a circle.

Two chords, BC and DE intersect at a point F inside the circle.

A chord of a circle is a straight line segment whose endpoints both lie on the circle.

To know the chord length,  we need to know the radius or central angle or the perpendicular distance to the center.

Given that f(x) = 2x + 5 and g(x) = x − 7, solve for f(g(x)) when x = −3
dusya [7]

Answer:

-15

Step-by-step explanation:

start from the inside and go out.

So first plug in -3 into g(x)

g(-3) = -3 - 7 = -10

then plug in -10 into f(x)

f(-10) = 2(-10) + 5 = -15

so f(g(x)) = -15

Answer:

22°

Step-by-step explanation:

what you do is you take the angles 35° and 90°

You add them up, that would be 125°

the actual equation would be

35+90=180

 125=180

-125

2. Water is leaking from a faucet at a constant rate of 1/3 gallon per minute.
Cloud [144]

Answer:

W = \frac{1}{3}t

20 gallons of water is leaked after an hour.

Step-by-step explanation:

Water is leaking at a constant rate of 1/3 gallon per minute.

a) We have to write a linear equation in two variables that show the amount of water, w, in gallons, that is leaked from the faucet after t minutes.

So, the equation is W = \frac{1}{3}t ......... (1) (Answer)

b) Now, if t = 1 hour i.e. 60 minutes, then from equation (1) we can write

W = \frac{1}{3}\times 60 = 20 gallons.

Therefore, 20 gallons of water is leaked after an hour. (Answer)

in a fundraiser, Mrs. Smith pledges $1 for each mile walked . if Sam walks 20 miles how much will Mrs. Smith donate? what is yhe
EleoNora [17]
Mrs. Smith donated $20
The constant proportionality is $1 because no matter what, Mrs. smith will donate $1 for each mile. So if Sam were to only walk 1 mile, mrs. smith would donate $1. Or seen as a 1:1 proportion.
