Answer:
not appropriate
Step-by-step explanation:
A linear model is not appropriate because the residual plot does not show a linear pattern.
we know that
the equation of a circle with the center at the origin is equal to

step 1
with the point (3,0) find the value of the radius
substitute the values of

in the equation of the circle above
so



step 2
with the radius find the area of the circle
area of the circle is equal to

for 

units²
therefore
the answer is
the area of the circle to the nearest hundredth is
units²
Answer:
Sin A = 0.6896
Cos A = 0.7241
Tan A = 0.9524
Step-by-step explanation:
Using SOH-CAH-TOA
Sin A = Opposite / Hypotenous
= 20 / 29
= 0.6896
Cos A = Adjacent / Hypotenous
= 21 / 29
= 0.7241
Tan A = Opposite / Adjacent
= 20 / 21
= 0.9524
Solution:
Given:
Using the trigonometric ratio of cosine,

Therefore, OPTION A is correct.
