Answer:
C = 25.12 feet
Step-by-step explanation:
C = 2 x 3.14 x 4
C = 25.12 feet
when given SAS, the area (A) of the triangle = (side1 · sin θ · side2)/2
A = (36 · sin 45° · 36)/2
= (36² · √2)/4
= 9 · 36 · √2
= 324√2
≈ 458.2
Answer:
the solution of the equation is: ![(-\infty,-3)\cup (2,7)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-3%29%5Ccup%20%282%2C7%29)
Step-by-step explanation:
we are given the expression as ![\frac{x^2+x-6}{x-7}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2%2Bx-6%7D%7Bx-7%7D%3C0)
=![\frac{(x-2)(x+3)}{(x-7)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x-2%29%28x%2B3%29%7D%7B%28x-7%29%7D%3C0)
we will use the number line rule for inequalities(first by making the coefficients of x positive then taking the roots on the number line and depending on the sign in the equation we start taking alternate signs and depending on the inequality take the desired region)
we get
.
This is the answer y=-4x-4
