Answer: The first radio button choice 8/3 * m^8
Steps:
120 (m^ 16) / 45 (m^8) =
120/45 * (m^16)/(m^8) =
Simplify 120/45 (15 or 5 *3 divides each). Since base "m" is same in both terms simply subtract exponents.
8/3 ( m^(16 - 8)) =
8/3 * m^8

Answer:
The other leg is 12 cm long.
Step-by-step explanation:
c
2
=
a
2
+
b
2
,
where:
c
is the hypotenuse, and
a
and
b
are the other two sides (legs).
Let
a
=
9 cm
Rearrange the equation to isolate
b
2
. Plug in the values for
a
and
c
, and solve.
b
2
=
c
2
−
a
2
b
2
=
(
15 cm
)
2
−
(
9 cm
)
2
Simplify.
b
2
=
225 cm
2
−
81
cm
2
b
2
=
144 cm
2
Take the square root of both sides.
b
=
√
144 cm
2
Simplify.
b
=
12 cm
Answer:
- 77
Step-by-step explanation:
To evaluate, substitute x = 4 into g(x) then substitute the value obtained into f(x).
g(4) = 4² + 3 = 16 + 3 = 19
f(19) = (- 4 × 19) - 1 = - 76 - 1 = - 77
