Answer:
Step-by-step explanation:
exponential function : 
where a = y intercept and b = factor ( what you multiply by )
looking at the table the y intercept is at (0,10) so a = 10
so we now have y = 10 * (b)^x
to find the factor we simply plug in one of the ordered pairs.
note that the ordered pair chosen does not effect the outcome
i chose (2,250)
we have y = 10 * (b)^x
(x,y) = (2,250)
250 = 10 * (b)^2
divide both sides by 10
25 = b^2
take the square root of both sides
5 = b
the final equation would be f(x) = 10 * (b)^x
Answer:
y=1/4x+3
Step-by-step explanation:
Slope intercept form is written as (y=mx+b)
<u>To define those variables:</u>
- m is the slope
- b is the y-intercept
We have been given both the slope, and the y intercept, therefore just plug in the numbers into the form:
y=1/4x+3
Attached is a picture showing the plot in the plane.
Note that for a complex number , x + iy.
The real part of the number is put on the x axis and the imaginary part is put on the y axis.
So plotting:
A = 4 + 1i
B = 9 + 7i
C = 5 + 8i
See picture.
Answer:
572
Step-by-step explanation:
10%=88
5%=44
30%=264
35%=308= favourite colour blue
