Answer: 30

Step-by-step explanation:

<u>First find f(2)</u>

f(2) = 2(2) + 1 = 4 + 1 = 5

Therefore g(f(2)) = g(5)

<u>Now solve for g(5)</u>

g(5) = (5)² + 5 = 25 + 5 = 30

Answer:

30 if that is an $x^{2}$ in g(x)

Step-by-step explanation:

f(2) = 2x + 1

= 2(2) + 1

= 4 + 1

f(2) = 5

g(5) = $x^{2}$ + 5

= $5^{2}$ + 5

= 25 + 5

g(5) = 30

Find the area of a sector with a central angle of 120° and a diameter of 7.3 cm. Round to the nearest tenth.

Andru [333]

Answer: $14cm^{2}$

Step-by-step explanation:

diameter=7.3cm

radius= $\frac{diameter}{2}$

= $\frac{7.3}{2}$

=3.65cm

angle =120°

area= $\frac{angle (tita)}{360}$ × $\frac{\pi r^{2} }{1}$

= $\frac{120}{360}$ × $\frac{22}{7}$ × $3.65^{2}$

= $13.95cm^{2}$

≅ $14cm^{2}$
