Answer:
Step-by-step explanation:
- −5.93 + (−8.62) + 5.93 =
- −5.93 - (8.62 - 5.93) = B
- −(5.93 + 8.62) + 5.93 = C
- −5.93 −8.62 - (- 5.93) = D
- -8.62 A
The output y is 
Explanation:
The expression is 
We need to determine the output y, when the value of input is x is 5.
That is, substituting
in
, we get,

Multiplying the value within the bracket, we have,

Subtracting the terms, we get,

Thus, the value of output y is 
Answer:
∅1=15°,∅2=75°,∅3=105°,∅4=165°,∅5=195°,∅6=255°,∅7=285°,
∅8=345°
Step-by-step explanation:
Data
r = 8 sin(2θ), r = 4 and r=4
iqualiting; 8.sin(2∅)=4; sin(2∅)=1/2, 2∅=asin(1/2), 2∅=30°, ∅=15°
according the graph 2, the cut points are:
I quadrant:
0+15° = 15°
90°-15°=75°
II quadrant:
90°+15°=105°
180°-15°=165°
III quadrant:
180°+15°=195°
270°-15°=255°
IV quadrant:
270°+15°=285°
360°-15°=345°

Answer: 30.72 miles per gallon
To find <span>best approximate for the average gas mileage at a speed of 60 miles per hour you need to replace the variable x with 60. The calculation would be:
</span><span> y=−0.0088x2+0.79x+15
y= -31.68 +47.4 + 15
y= 30.72
