Answer:
A=z
B=-2
C=0
D=30
Step-by-step explanation:
First lets simply the equation
21 - (2x +3)2 + 4(1-1) + z^3
21 - (2x^2 + 9) + 4(0) + z ^3
21 - 2x^2 + 9 + z^3
- 2x^2 + z ^3 + 30
This means that:
A=z
B=-2
C=0
D=30
Answer:
40 cm.
Step-by-step explanation:
Given,
height of the object = 10 cm
Distance of the object from the X-ray= 50 cm
Distance of detector from the source = 2 m = 200 cm
Height of the image, h = ?
Now,



Again applying


h = 40 cm
Hence, height of the image is equal to 40 cm.
Answer:
33π FT^2
Step-by-step explanation:
A=πr(r+(h2+r2)^1/2)
= π3(3+8)
=33π
Answer:
Option B.
Step-by-step explanation:
Let
b------> the number of buses
we know that
-----> inequality that represent the situation
Solve for b
Two angles that have the sum of 180 degrees are supplementary angles. If you need to find angle A, you just need to subtract angle B from 180 degree to find out the degree of the particular angle. Hope I helped.
