PLEASE HELP ASAP ): 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
eimsori [14]

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.)

Scott took out a 72 month loan for $35,000 to purchase a new boat. If Scott paid $8,925 in simple interest, what was the interes
diamong [38]

Answer:

Option 4.7% = 3,500 x 4.7% =$164.50 simple annual interest.

82.25 this is what Scott will pay in 6 months at simple interest.

 

Option 4.2% =3,500 x (1 +0.042/12)^6 =3,500 x 1.0035^6=$3,574.15.

3,500 =$74.15 this is what Scott will pay in 6 months at compounded interest.

 

The compound option is cheaper by: 74.15 =$8.10.

How do you explain how to get h(t)=7(t-25)
Nutka1998 [239]
Hey There! :)

To Solve for t.
h(t)=7(t-25)
Distribute the brackets.
h(t)=7*t-7*25
h(t)=7t-175
Subtract 7t from both sides.
(h(t))-7t=(7t-175)-7t
(h(t)-7t=-175
h*t-7t=-175
Factor out variable, t.
t(h-7)=-175
Divide both sides by h-7.
(t(h-7))/h-7=(-175)/h-7
t=-175/h-7

Hope this helps!

Anvisha [2.4K]

Answer:

\large Q1:\ x=18\ ft\\\\Q2:\ 6\ inches

Step-by-step explanation:

Q3.

If ΔGHI and ΔJKL are similar, then the sides are in proportion:

\dfrac{JL}{GI}=\dfrac{LK}{IH}

We have

JL = x, GI = 9 ft, LK = 24 ft, IH = 12 ft.

Substitute:

\dfrac{x}{9}=\dfrac{24}{12}

\dfrac{x}{9}=2         <em> multiply both sides by 2</em>

x=18\ ft

Q4.

We must multiply the original length by a scale factor of 3/4:

\dfrac{3}{4}\cdot8\ in=\dfrac{3}{1}\cdot2\ in=(3)(2)\ in=6\ in
