Step-by-step explanation:

Part b:  Find the length of the sidewalk.  The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3.  Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:

                                     

cos 30° = adj / hyp, or:

                           

  √3       2√3

 ------- = --------

     2        hyp

This simplifies to

     1          2

 -------- = -------

      2        hyp

Cross multiplying results in:  hyp = 4.  The sidewalk length is 4 miles.

a.  The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:

                               1       opposite side

sin 30 degrees = ----- = -------------------------   or 2(opp side) = 4.

                               2                 4

Then the opp side, which is the width of the park, is 2.

The total surface area of a cylinder with height 5 in. is given by the function g(x) = 2πx2 + 10πx, where x is the radius, and the function f(x) = 10πx gives the surface area of the side of the cylinder. Which combined function gives the total surface area of the two bases of the cylinder? A. f + g B. f – g C. g – f D. f · g

Answers

Answer:

C. g - f

Step-by-step explanation:

Total surface area of a cylinder with height 5 is:

A = 2πrh + 2πr² = 10πr + 2πr²

If we substitute r with x, we get:

g(x) - full surface areaf(x) - surface area

Total surface area of two bases:

g - f = 2πx² + 10πx - 10πx = 2πx²

Correct choice is C

What is the slope of the line?

Answers

Answer:

1/2

Step-by-step explanation:

y = mx + b is slope intercept form.

b = y intercept. where the line first passes through on the y axis

that number is 3.

y = mx + 3.

to find M (slope) you have to do RISE / RUN.

Run is going left or right from a point

Rise is going up or down from a point.

To make sure you find the slope, when you Rise and Run, it has to hit another point on the graph.

From the y - intercept 3, RISE (go up) 1 and RUN (go left) 2.

So, the slope is 1/2.

A stepladder has an angle of elevation of 60° with the front of the house. The length of the stepladder is 24 feet. At what height does the stepladder meet the house?

Answers

Answer:

20.78 feets

Step-by-step explanation:

Based on the solution diagram attached below :

The height at which the step ladder meets the house can be obtained thus :

Using trigonometry :

Sin θ = opposite / hypotenus

Sin θ = h / 24

Sin 60 = h / 24

0.8660254 = h/24

Height, h = 0.8660254 * 24

Height, h = 20.78 feets

Leticia bought a new tablet for $425. She had to pay a sales tax of 8%.


What was the amount of sales tax she paid on the tablet?               Sales Tax: $


What was the total cost after sales tax that Leticia paid for the tablet?      Total: $


​

Answers

Sale Tax: $34
Total: $459

Step to solve:
To find sale tax you would need to multiple 425, the cost of the tablet by 8% or 0.08 in decimal form to get the answer 34.

To find the total add the sale tax, 34, and the cost of the tablet, 425, to get the total, 459 dollars.
