Jack is trying to determine how he can save money by cutting his electricity bill. He is currently on a standard use plan for el

faust18 [17]

Jack's current monthly bill is
(1200 kWh +400 kWh)*($0.075/kWh) = $120

On the interval use plan, Jack's monthly bill would be
(1200 kWh)*($0.03/kWh) + (400 kWh)*($0.15/kWh) = $36 + 60 = $96

If Jack were to switch, his savings would be $120 -96 = $24.

The appropriate choice is ...
b. Jack should switch to the interval use plan, which would save him $24 per month.

<u>Answer:</u>

$\frac{200}{3}$ square units

<u>Step-by-step explanation:</u>

Knowing the function and that the triangle is formed by both the x and y-axis, you already have the triangle's height, which is 10 (the y-intercept of the functon) To find the base length, all you have to do is find the x-intercept. To do that, simply:

Set function equal to 0 and solve for x:

f(x) = 10 - $\frac{3}{4}$ x

0 = 10 - $\frac{3}{4}$ x

$\frac{3}{4}$ x = 10

x = $\frac{40}{3}$

This means that the base length of the triangle is also $\frac{40}{3}$ . Now that you have the height and base length, you can

Plug values into the formula for the area of a triangle:

The area of a triangle is $\frac{1}{2}$ × height × base

Height = 10, base = $\frac{40}{3}$

Area = $\frac{1}{2}$ × 10 × $\frac{40}{3}$

Area = 5 × $\frac{40}{3}$

Area = $\frac{200}{3}$

A ladder is leaning up against a 70 foot wall at an angle of elevation of 38° how far is the foot of the latter from the wall? R

SIZIF [17.4K]

Tanα=h/x

x=h/tanα

x=70/tan38 ft

x≈89.6 ft (to nearest tenth of a foot)

Note: the question seems strange, (because this would make the ladder almost 114 feet long!) or are we to assume as I did that the ladder is leaning against a point 70 feet high, or should if be a 70 foot ladder leaning against a wall of unknown height?

If it is just a 70 ft ladder at a 38° inclination the:

cosα=x/L

x=Lcosα

x=70cos38° ft

x≈55.2 ft
