Answer:

c. 25

Step-by-step explanation:

(f ∘ g)(-2) = f(g(-2)) = f(-2-3) = (-5)² = 25

For this problem, it seems to work best to evaluate g(-2), then evaluate function f on that. (In other cases, it might be useful to simplify the composite function first.)

A circle is divided into three arcs of measures x 2x and 3x what’s the value of x

lidiya [134]

Answer:

60°

Step-by-step explanation:

This questions tests our knowledge on arcs and arc measures.

-Arc measure is the angle that an arc makes with the circle's center.

-The arc measure is proportional to the arc.

#The sum of the 3 arcs is x+2x+3x=6x

Given a circle has 360°, the arc measurement x can be calculated as:

$[x+2x+3x]=360\textdegree\\\\6x=360\textdegree\\\\x=60\textdegree$

Hence, the arc measurement x is 60°

Which of these triangle pairs can be mapped to each other using a single reflection?

kondor19780726 [428]

Answer:

Second triangle pair

Step-by-step explanation:

In a reflection, the shape is flipped. In the first pair, the corresponding sides as shown by the lines, and the corresponding angle are already in the same position. In the second pair, Δ MLN can be reflected so that line LN match with EG and line LM matches with line EF. ∠L and ∠E will also be mapped to each other when one triangle is reflected.

What is the volume of the composite figure? Round your answer to the nearest hundredth. Use 3.14 for π.

Reil [10]

Answer:

263.76 in^3

VOLUME OF FIGURE=VOL.OF CONE+VOL.OF CYLINDER +VOL.OF HEMISPHERE

=(1/3×3.14×3×3×4)+(3.14×3×3×6)+(2/3×3.14×3×3×3)

=37.68+169.56+56.52

=263.76in^3
