Find the length of the missing side.

Mathematics
1 answer:
jenyasd209 [6]2 years ago

Answer:

68 ft

Step-by-step explanation:

to find the length of the missing side we can use the Pythagorean Theorem which is a² + b² = c², where <em>a</em> and <em>b</em> are sides (legs) of the triangle and <em>c</em> is the hypotenuse. the hypotenuse of a right triangle is the side opposite of the right angle. using this information we can see the following:

sides of the triangle (a and b): 32 and 60

hypotenuse: c, our missing side

we plug these values into the formula

32² + 60² = c² < simplify the exponents

1024 + 3600 = c² < add

4624 = c² < square root both sides to get c on one side with no exponent

√4624 = √c² < simplify square roots

68 = c

the length of the missing side is 68ft. to see if this is right, we can plug it into the formula to check but its not necessary.

Find the x and y intercept for f(x)=x^2-3x-40
Dahasolnce [82]

To find the y-intercept, simply set the value of x equal to 0, and solve for y, or f(x).

f(x) = 0^2 - 3(0) - 40

f(x) = -40

<h3>The y-intercept is -40.</h3>

Because this is a 2nd degree polynomial, we cannot find the x-intercepts in one step, and must instead use one of a few different methods.

In this case, we're going to use the quadratic formula:

\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

Plug in the values.

3 +/- √(-3^2 + 160) / 2

3 +/- √169 / 2

3 +/- 13 / 2

(3 + 13) / 2 = 16 / 2 = 8

(3 - 13) = -10 / 2 = -5

<h3>The x intercepts are 8, and -5.</h3>
