Pythagorean theorem formula is a^2 + b^2 = c^2

7^2 + 11^2 = 170

You will get the value of c by square-rooting 170

Therefore, the answer is √170

There are actually 2 possibilities here:

1) a and b are the shortest 2 sides, and c is the longest side, and we assume that this is a right triangle.  Then 7^2 + 11^2 = c^2,  or  c^2 = 49 + 121 =170.
c is then sqrt(170)   (answer)

2) b is the hypo and a and c are the 2 legs.  Then 11^2 = 7^2 + c^2, and 
121-49 = c^2, so that c = sqrt(72), or sqrt(36)*sqrt(2) = 6*sqrt(2) (answer)

You are skiing down a mountain with a vertical height of 800 feet. The distance from the top of the mountain to the base is 1600
adoni [48]

Answer:

θ  = 30^{0}

Step-by-step explanation:

Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;

Sin θ = \frac{opposite}{hypotenuse}

Sin θ = \frac{800}{1600}

        = 0.5

θ = Sin^{-1} 0.5

θ  = 30^{0}

Thus, the angle of elevation from the base to the top of the mountain is 30^{0}.

Keith exercises x hours a week. Troy exercises three hours less than Keith and Joe exercises two times more than Troy. Which exp
umka21 [38]
If Keith is represented by x, and Joe is three less than Keith, Troy is represented by x-3. 
Then, we know that Joe exercises for twice the amount of time as Troy, we multiply the expression for Joe by two. 

Keith = x
Troy = x-3
Joe = 2(x-3)

Determine if the coordinate (6, 8) lies on the circle x^2 + y^2 = 100. <br>​
SVEN [57.7K]

Answer:

x² + y² = 100

6² + 8² = 100

36 + 64 = 100

100 = 100

Because this is a true statement, the answer is yes, it does lie on the circle.

What is the sum of a seven-term geometric series if the first term is -2, the last term is
ExtremeBDS [4]

Answer:

-26042

Step-by-step explanation:

sum of a finite geometric series =

\frac{a_1(1-r^n)}{1-r}

here, a1 is the first term, r is the common ratio, and n is the number of terms

a1 = -2

r = -5

n = 7

\frac{a_1(1-r^n)}{1-r} = \frac{-2(1-(-5)^7)}{1-(-5)} = -26042
