1. What is the value of x? Do not convert to decimal. Keep your answer in exact (radical) form. Show all of your work. This is P
lesya [120]

Answer:

The value of x is \sqrt{113}.

Step-by-step explanation:

It is given that hypotenuse is \sqrt{177}. So, the legs would be x and 8.

Let's use Pythagoras theorem,

a^{2} +b^{2} =c^{2}

Plug in the numbers to solve for x.

x^{2} +8^{2} =\sqrt{177} ^{2}

Simplify it

x^{2} +64 =177

Subtract both sides 64.

x^{2} =113

Take square root on both sides

x=\sqrt{113}

We can not simplify the radical.

So, let's keep this as answer.

Flying lessons cost $645 for an 8-hour course and $1425 for a 20-hour course. Both prices include a fixed insurance fee. a. Writ
Softa [21]

Answer:

Check Explanation

Step-by-step explanation:

a) Let the fixed insurance fee be A and the rate charged per hour be b

The equation for the cost, C, of flying lessons in terms of length, h, of the course in hours is given by

C = A + bh

b) The two points (h, C) given in the question are (8, 645) and (20, 1425)

c) To find the equation of the line passing through these two points,

equation of a straight line iS given by

y = mx + c (where m = slope of the line and c = intercept)

denoting hours (h) as x and Cost (C) as y

645 = 8m + c

1425 = 20m + c

Solving this simultaneous equation,

m = 65 dollars/hour and c = 125 dollars

The equation of the straight line is

y = 65x + 125

Written in the variables of the question,

C = 65h + 125

This shows that the fixed insurance fee, called A in part (a) = $125

And the rate charged per hour called b in part (a) = $65/hour

Hope this Helps!!!
