Hi!

So f(x) = 2x + 1
Since f(2), that means x = 2

f(2) = 5

Let's do a few more (the ones I don't do, you have to figure out!)

f(t + 1)...
f(t + 1) = 2(t + 1) + 1
f(t + 1) = 2t + 2 + 1
f(t + 1) = 2t + 3

g[f(m+2)]...
g[f(m+2)] = 2m + 5

Hope this helps! DM me if you need to know the rest. :)

Answer:

8 - 2π square units.

π/16 - 1/8 square units.

6π - 9√3 square units.

Step-by-step explanation:

The area of the square = 2√2 * 2√2

= 2*2*2

= 8.

The area of the circle = πr^2

= π * [ ( 2√2)/ 2) ]^2

=  π (√2)^2

=  2π.

Second Question:

The area of the circle = π(1/2)^2 = π/4.

Finding the area of the square:

1^2 = 2x^2

x^2 = 1/2

So the area of the square = 1/2

So the area of the red part = 1/4 ( π/4 - 1/2).

= π/16 - 1/8.

Third question

Area of the circle = 6^2 * π = 36π.

Now 60 degrees is 1/6 of 360 degrees so the are of the sector is 6π.

The area of the segment = 6π -  0.5 * 6^2 sin 60

= 6π - 18√3/2

= 6π - 9√3 square units.

4/r=5/7solve for r. Help pls
antiseptic1488 [7]
Hello!

You first cross multiply

4 * 7 = 28

5 * r = 5 * r

r * 5 = 28

Divide both sides by 5

r = 28/5 = 5.6

The answer is 28/5 or 5.6

Hope this helps!

Answer:

a = -b + 10x + 9/ x

Step-by-step explanation:

5(2x+3)−6=ax+b  

ax+b=10x+9  

ax +b+−b=10x+9+−b

ax=−b+10x+9

ax/x = -b+10x  + 9 /x

hope this helpss!!
