Step-by-step explanation:
Given
To find
Solution
- f(19) = 3/(19 + 2) - √(19 - 3) = 3/21 - √16 = 1/7 - 4 = - 27/7
Answer:
15/30:2/30
15/30=2/30x
divide by 15/30
7.5 is x
Step-by-step explanation:
Answer:
B. $50
C. y=25x+50
D. $550
Step-by-step explanation:
B. (0, 50) y=50
C. y=mx+b y=25x+50
D. y=25(20)+50 y=500+50 y=550
Answer:
A = 1/2 B H area = 1/2 base X height
B = 2 A / H = 2 * 99 / 12 = 16.5 cm
dA / d t = 1/2 * (B dH / dt + H dB / dt)
dB / dt = (2 dA / dt - B dH / dt) / H
dB / dt = (2 * 1.5 cm^2 / min - 16.5 cm * 2 cm / min) / 12 cm
dB / dt = (3 - 33) / 12 cm/min = -2.5 cm/min
Answer:
Option B
Step-by-step explanation:
Dilation does not change the value of angle.
so angle measurement should be same as before .
Angle A= 37
Scale factor is 3 so multiply length by 3
So A'C'= 3×5 =15
