Answer:
C. 39
Step-by-step explanation:
m∠3 ≅ m∠5
4x - 7 = 6x - 81
-7 = 2x - 81
74 = 2x
37 = x
m∠5 = 6(37) - 81 = 141
m∠8 = 180 - 141 = 39
Answer:
Exponential decay model
Step-by-step explanation:
A quick graph shows the remembrance pattern is not linear because the slope is not the same. Therefore a very likely remembrance pattern will be exponentially related.
Answer:
Slope = -8.000/2.000 = -4.000
x-intercept = -31/4 = -7.75000
y-intercept = -31/1 = -31.00000
Step-by-step explanation:
1: Graph of a Straight Line
2: Calculate the Y-Intercept
3: Calculate the X-Intercept
4: Calculate the Slope
5: Geometric figure: Straight Line
Answer: Slope = -8.000/2.000 = -4.000
Hope this helps.
The area of a circle is calculated as pi*(r^2). Given a diameter of 26 cm, the radius is half the diameter, which is 26/2 = 13 cm.
Therefore the area is pi*(13^2) = 169 pi.
Another alternative formula for the area is pi*(d^2 / 4). Substituting d = 26 would give pi*(26^2 / 4) = pi*(676/4) = 169 pi, which is the same answer.
So the correct answer is C.
