Answer:
D
Step-by-step explanation:
given p² + 4p - 12 = 0 ← in standard form
with a = 1, b = 4, c = - 12, then the discriminant
Δ = b² - 4ac
= 4² - (4 × 1 × - 12) = 16 - (- 48) = 16 + 48 = 64 → D

Answer: d = 47.3897287242421 approximately</h3>
Round this however you need to
=================================================
Explanation:
The reference angle is 56 degrees. The side 26.5 is adjacent to this angle as it is the leg closest to the angle (in contrast to the opposite leg or opposite side that is furthest from the reference angle)
The hypotenuse is d. The hypotenuse is always the longest side. The longest side is always opposite the largest angle of a triangle.
We will use the cosine ratio as it is the ratio of adjacent over hypotenuse
cos(angle) = adjacent/hypotenuse
cos(56) = 26.5/d
d*cos(56) = 26.5
d = 26.5/cos(56)
d = 47.3897287242421
You use your calculator for the last step shown above. Make sure your calculator is in degree mode. Round that value however you need to.
First we should change these mixed numbers into improper fractions:
We can find the number of crates used by dividing the total amount of electrical supplies by the amount that each crate can hold:
/
*
So now we know that
Otto used 7 crates.
