Answer:
y = 4 sin( 0.5t - 
) - 2
y = a sin ( 2t - 
) + 2
Step-by-step explanation:
In the first question,
amplitude = 4
Period = 
phase shift = 
Vertical shift = -2
Angular velocity , w = 
Here, w = 
= 0.5
The general equation of a wave is
y = a sin( wt + ∅ )
Putting above values in the equation,
y = 4 sin( 0.5t - ) - 2
In the second question,
Amplitude is not given so we will take it as a.
time period = 
w = 2
Phase shift =
Vertical shift = 2
The equation is
y = a sin ( 2t - ) + 2
Vol (pyr) = 1/3 b × h, where h = 15 and b = base = area of triangular base = 1/2 b×h, where h = 12 and b = 13
V = 1/3 (1/2×12×13)×15
V = (1/3×1/2×12)×13×15
V = 2×13×15 = 30×13 = 390 in^3
Answer: 22
Step-by-step explanation:
4 - (-18) = 4 + (+ 18) = 22
Answer:
Find in Step by Step
Step-by-step explanation:
x-intercept = 26/-4 = 13/-2 = -6.50000
y-intercept = 26/1 = 26.00000
Slope = 8.000/2.000 = 4.000
Equation at the end of step 1 :
(y - 6) - 4 • (x + 5) = 0
Step 2 :
Equation at the end of step 2 :
y - 4x - 26 = 0
Step 3 :
Equation of a Straight Line
3.1 Solve y-4x-26 = 0
