Answer:

39

Step-by-step explanation:

f(x) = 2x - 1.....(1) \\ g(x) = 3x + 5....(2) \\ plug \: x = 5 \: in \: (2) \\ g(5) = 3 \times 5 + 5 = 15 + 5 = 20 \\  \therefore \: f(g(5)) = 2 \times 20 - 1 = 40 - 1 = 39 \\  \\   \huge \red{ \boxed{\therefore \: f(g(5)) =39}}

I need help with this question. Can you please help me. I’ll give you 18 points if it’s correct
lukranit [14]

Answer:

34.4

Step-by-step explanation:

Using Triangle Sum Theory, you see that the triangles are similar. They have the same angle measurements. That means their corresponding sides are proportional.

\frac{MN}{NO} = \frac{PQ}{QR}

\frac{14}{11} = \frac{PQ}{27}

Cross multiply

14(27) = 11(PQ)

378 = 11(PQ)

\frac{378}{11} = PQ

PQ = 34.4

We use the formula V = πr2h to find the volume of a cylinder. Make h the subject of the formula.
Gennadij [26K]

Answer:

V / ( pi r^2)  = h

Step-by-step explanation:

V = pi r^2 h

Divide each side by pi r^2

V / ( pi r^2)  = pi r^2 h / pi r^2

V / ( pi r^2)  = h

Find the radius of circle if AB = 24 and OC = 5
Likurg_2 [28]

Answer:

13

Step-by-step explanation:

Since OCB forms a right triangle, you can find the length of side OB and therefore the radius by simply using the pythagorean theorem. The first step is to note that, since AB=24 and OC bisects that, that both CB and AC have length 12. Therefore, the radius is BO=\sqrt{12^2+5^2}=13. Hope this helps!
