80% = 0.8
0.8 * 56 = 44.8 rounded to 45
The student got 45 answer correct.
Answer:
-1.5x - y + 7 = 0
Step-by-step explanation:
The formula for point slope form is y-yA = m(x - xA).
y - (-2) = -1.5(x + 6)
y + 2 = -1.5x + 9
y = -1.5x + 9 - 2
y = -1.5x + 7
-1.5x - y + 7 = 0 is the point slope form.
The answer is : f(x) =3sin(2x+pi/2)
Explain
There 0,3 on the graph
You use this formula
f(x)=asin(kx-c)+h
and the maximum and minimum value of this function
a+ h and -a+ h
So a=3 and h=0
So we have
We have; f(x)= 3sin(kx - c)
and we have from the graph;
f(O)=3
So
Sin(-c) =-1
Therefore C=. Pi/ 2 +2pi n
We have period of the function is pi
2pi/ k
k=2
So it will equal Pi

Answer:
I beleive the answer is $9000
Step-by-step explanation: What is 18% of 50000?
Y is 18% of 50000
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 18% * 50000
Converting percent to decimal:
p = 18%/100 = 0.18
Y = 0.18 * 50000
Y = 9000
