Answer:
f(1)=-3
f(-4)=-11
f(6)=0
Step-by-step explanation:
Use the correct formula depending on what (x) equals.
When (x=1) you use the second formula because 1 is greater than -2 but less than 4
When (x=-4) you use the first formula because -4 is less than -2
When (x=6) you use the third formula because 6 is greater than 4
Answer:
63%
Step-by-step explanation:
37% did not solve problem 2

Answer: 109.69
Step-by-step explanation:
100-35=65
168.75 • 65= 10,968.75/ 100= 109.69
As the angle is greater than 0° and less than 90°, then the angle ABC is acute. (Answer: A)
<h3>How to determine the features of an angle set on Cartesian plane</h3>
Herein we find the locations of the three vertices of the figure, of which we must determine the lengths of the two sides of the angle and determine the value of the angle by trigonometry:
BA = 5, BC = 2
θ = tan⁻¹ (BA / BC)
θ = tan⁻¹ (5 / 2)
θ ≈ 68.199°
As the angle is greater than 0° and less than 90°, then the angle ABC is acute. (Answer: A)
