Find side BC for the triangle shown (round to the nearest tenth).
Answer: 2.6 (rounded answer)
Step-by-step explanation: To solve for the side BC we can find the tangent (TAN) of 41 degrees. Since the tangent of an angle is equal to the opposite side over adjacent, we can set up an equation that looks like this, assigning side BC to be x:
tan(41)= x/16
0.1606567=x/16 <---- Use calculator to find tan(41)
0.1606567(16)=x/16(16) <---- Multiply each side by 16
2.5705071789=x

Which measurement is closest to the circumference of a circle with an area of 36 square feet?
A
12.0 feet
B
21.3 feet
С
103.2 feet
D
113.0 feet
The measurement of the circumference of a circle is 21.3 ft.
What is Circumference of Circle?The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.
Here, given area of circle = 36 ft²
Area of Circle = πr²
36 = 3.14 X r²
r² = 11.46
r = 3.38 ft.
Circumference of Circle = 2πr
= 2 X 3.14 X 3.38
= 21.25 ft. ≈ 21.3 feet
Thus, the measurement of the circumference of a circle is 21.3 ft.

what is the slope of the line containing the points (1,10) and (-3,10)
Answer:
0
Step-by-step explanation:
Slope is Rise over Run (y / x).
For 2 points, you would take the difference of y-coordinates and divide by the difference of x-coordinates.
(Y1 - Y2) / (X1 - X2)
Since both y-coordinates are the same (ten minus ten), your slope is zero (zero divided by anything is zero).

True or false: a line best fit is always an estimate and cannot be calculated
Answer:
I think it’s true.
Step-by-step explanation:
The line best fit has been an estimate and cannot be calculated has been True.
The line best fit can be explained as the line formed by the adjoining of the majority of the points in a scatter plot, The best fit line can be in the shape of a straight line or a curve based on the points on the scatter plot.
The best fit helps in explaining the relationship between the variables in the scatter plot. The best fit has the maxima scattered point as the starting point of the line best fit.
The line best fit has been an estimated line about the straight-line equation fits the plot or not. Thus the measurement of line best fit has not been possible.
The given statement has been True.
