Step-by-step explanation:
6a)

6b)

The first one is D
The second one is true
<span>127.3 feet
This problem requires the use of pythagoras theorem. Ignore the face that it's a baseball diamond. All you're concerned with is that you have a square that's 90 feet per side and you want to know what the length of the diagonal. So you have a right triangle with 2 sides of 90 feet each and you want to know the length of the hypotenuse.
The formula is
C^2 = A^2 + B^2
Both A and B are 90, so plugging them into the formula gives
C^2 = 90^2 + 90^2 = 8100 + 8100 = 16200
So
C^2 = 16200
Take the square root of both sides
C = 127.2792
Round to the nearest tenth, giving
C = 127.3</span>
Answer:
h = -6
Step-by-step explanation:
Use the quadratic formula
ℎ

√

h=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
h=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
