Given:
Amplitude of cosine function, A=3.
Period, T=7π/4.
Midline, D=2.
The time period can be expressed as:
Put T=7π/4 to find the value of B.
The general cosine function can be expressed as,
Substitute B=8/7, A=3 and D=2 in above equation.
Therefore, the cosine function is,
Answer:
<em>start with g </em>
g
<em>subtract 7</em>
g-7
<em>multiply by 3</em>
3(g-7)
<u>Therefore the expression is </u>
3g-21
Y=3x-34
y=2x-5
both are equal to y
3x-34=y=2x-5
3x-34=2x-5
minus 2x both sides
x-34=-5
add 34both sides
x=29
sub back
y=2x-5
y=2(29)-5
y=58-5
y=53
x=29
y=53
(29,53)
Answer:
3.145 Hours
Step-by-step explanation:
37÷2=18.5
18.5×.17=3.145
Answer:
b.) x = -8
Step-by-step explanation:
Solve -4*(2x + 3) = 2x + 6 - (8x + 2)
-8x + -12 = 2x + 6 - 8x - 2
-8x - 12 = -6x + 4
-12 = 8x - 6x + 4
-12 = 2x + 4
-12 - 4 = 2x
-16 = 2x
x = -8
