Equation D. 
can be used to solve y in feet.
Step-by-step explanation:
Step 1:
According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The hypotenuse is the side opposite the right angle. So the hypotenuse of this given triangle is 12 feet.
The other two sides of the triangle are 4 feet long and y feet long.
Step 2:
Substituting the values we know in the Pythagorean theorem, we get
which can also be written as
This is option D.
Answer:
irrational
Step-by-step explanation:
it is not a perfect square.
square root of 72= 8.48528137424...
Square base means the bottom is 6 x 6 = 36 in^2
There are four triangular sides whose area can be measured by using (b x h)/2, which is (6 x 5)/2 = 15 in^2 per side, so 15 x 4 = 60 in^2, plus the bottom which makes a total of 96 in^2
Answer:
<u>The correct answer is D. -5 +/- i√2</u>
Step-by-step explanation:
Let's solve for x, the equation given to us, this way, using the quadratic formula:
x = (- b +/- √b² - 4ac)/2a
Replacing with the real values, we have:
x = (-10 +/- √10² - 4 * 1 * 27)/2
x = (-10 +/- √100 -108)/2
x = (-10 +/- √-8)/2
x = (-10 +/- √-1 * 4 * 2)/2 Let's recall that √-1 = i
x = (-10 +/- 2i√2)/2
x = 2 (-5 +/- i√2)/2 (Dividing by 2 both the numerator and the denominator)
<u>x₁ = -5 + i√2</u>
<u>x₂ = -5 - i√2</u>
<u>The correct answer is D. -5 +/- i√2</u>
