Answer:
I will be using differentiation method
Step-by-step explanation:
x^2+5x =-8
2×x ×x^2-1 +5x = -8
2x +5x = -8
7x = -8
divide both sides by the co-efficient of x
7x÷7=-8÷7
x =-1.5
Answer:
x =
; y = 2
Step-by-step explanation:
You have a 45 -45 - 90 triangle. There are two things to know"
1. The hypothenuse = leg × ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
2. The legs are equal.
The hypothenuse is opposite the right angle that is "y" in this problem.
Hypothenuse = leg × ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
= ![\sqrt{2} \sqrt{2} = \sqrt{4} = 2](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D%20%20%20%5Csqrt%7B2%7D%20%3D%20%5Csqrt%7B4%7D%20%3D%202)
The legs are =
Therefore x = ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
1/2 becuase they are in between i think hope this helps
Answer:
9.74 feet
Step-by-step explanation:
the formula for finding a hypotenuse is
. We can rearrange that to get:
. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.
