Which equations for the measures of the unknown
MAXImum [283]

Answer: Option B, Option C, Option E

Step-by-step explanation:

The options written correctly, are:

A)x = cos^{-1}(\frac{a}{c})\\\\B) x = sin^{-1}(\frac{c}{b})\\\\C)x = tan^{-1}(\frac{c}{a})\\\\D) y = sin^{-1}(\frac{a}{c})\\\\ E)y = cos^{-1}(\frac{c}{b})

For this exercise you need to use the following Inverse Trigonometric Functions:

1)\ sin^{-1}(x)\\\\2)\ cos^{-1}(x)\\\\3)\ tan^{-1}(x)\\\\

When  you have a Right triangle (a triangle that has an angle that measures 90 degrees) and you know that lenght of two sides, you can use the Inverse Trigonometric Functions to  find the measure of an angle \alpha:

 1)\alpha = sin^{-1}(\frac{opposite}{hypotenuse}) \\\\2)\ \alpha =cos^{-1}(\frac{adjacent}{hypotenuse})\\\\3)\ \alpha=tan^{-1}(\frac{opposite}{adjacent})

Therefore, the conclusion is that the angles "x" and "y" can be found with these equations:

x=sin^{-1}(\frac{c}{b})\\\\x= cos^{-1}(\frac{a}{b})\\\\x=tan^{-1}(\frac{c}{a})\\\\\\ y=sin^{-1}(\frac{a}{b})\\\\y=cos^{-1}(\frac{c}{b})\\\\y=tan^{-1}(\frac{a}{c})

How can you tell from the scale factor whether the original figure was enlarged or reduced?
Stels [109]

If the scale factor is less then 1, it was reduced.

If the scale factor is more than 1, it was enlarged.

If it is equal to 1, it is the same.

Hope this helps!

The populations of two cities after t years can be modeled by -150t+50,000 and 50t+75,000 . What is the difference in the popula
creativ13 [48]

Answer:

The difference in the populations of the cities when t=4 is 25,800.

Step-by-step explanation:

Given equations each of the city:

-150t+50,000

and

50t+75,000

To find the difference between the population when t=4, we first have to solve both equation when t=4.

For both equations, substitute 4 into t:

-150(4) + 50,000 = 49,400

50(4) + 75,000 = 75,200

Now subtract 49,400 from 75,200 and you get 25,800.

The difference in the populations of the cities when t=4 is 25,800.

it takes eddie 2 hours to shovel the snow from a driveway and sidewalk. brad can shovel the snow from a driveway and sidewalk in
Arada [10]

Answer:

The time required  them working together to shovel the snow is T = 1.428 hours

Step-by-step explanation:

Given data

Time taken by first person to shovel the snow T_1 = 2 hours

Time taken by second person to shovel the snow T_2 = 5 hours

Time taken by both persons to shovel the snow

\frac{1}{T}  = \frac{T_1+T_2}{ (T_1) (T_2)}

Put all the values in above equation we get

\frac{1}{T}  = \frac{2 +5}{(2)(5)}

T = 1.428 hours

Therefore the time required  them working together to shovel the snow is T = 1.428 hours
