Answer: E: 100%
Step-by-step explanation:
If the class average is currently 70% and she wants to increase it by 10% every week for 3 weeks, 10×3=30% and 70+30= 100%.

Answer:
the desired equation is y = -5x + 2
Step-by-step explanation:
The general slope-intercept form is y = mx + b. Here we know that m = -5 and b = 2, so the desired equation is y = -5x + 2.
The value of x is 126.87° and the value of y is 53°.
<h3>What is an obtuse and an acute angle?</h3>
An obtuse angle is an angle that is greater than 90° but lesser than 180° while an acute angle is an angle between 0-90°.
From the given information:
sin x° = 0.8
x = sin⁻¹ (0.8)
x = 53.13°
x + 53.1° = 180°
x = 180° -53.13°
x = 126.87°
If cos 127° = -cos y°,
-cos y = -0.6018
cos y = 0.6018
y = cos⁻¹ (0.6018)
y = 53°
