Answer:
Step-by-step explanation:
Wow, pretty harsh. Report someone who makes a fair effort but makes a mistake. Better report yourself then, because you obviously cannot do it yourself or you wouldn't be asking.
Coordinates of the vertex seem to be (-2, 2)
It's the point where the slope of the curve is zero.
Cannot tell for certain unless we have the equation of the curve.

<h3>
Answer: angle B = 47 degrees</h3>
========================================
Work Shown:
Use law of cosines to find angle B
b^2 = a^2 + c^2 - 2*a*c*cos(B)
9^2 = 6^2 + 12^2 - 2*6*12*cos(B)
81 = 36 + 144 - 144*cos(B)
81 = 180 - 144*cos(B)
81 - 180 = -144*cos(B)
-99 = -144*cos(B)
-144*cos(B) = -99
cos(B) = (-99)/(-144)
cos(B) = 0.6875
B = arccos(0.6875)
B = 46.5674634422102
B = 47 when rounding to the nearest whole number
Make sure your calculator is in degree mode.
arccos is the same as inverse cosine often labeled 
on calculators.
Answer: E. (126 + 10.5x) square feet
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
The length of a living room is 12 feet and its width is 10 1/2 feet. If the length of the room is being expanded by x feet, then the new length would be (12 + x) feet
Therefore, an expression to represent the new area of the living room in square feet would be
10.5(12 + x)
The expanded form of the expression would be
(126 + 10.5x) square feet
Hi there.
To convert ounces to pounds, we use the formula
gives us 6 lbs.
