Answer:
D. y = 10 • 4x
Step-by-step explanation:
Answer: As seen from the graph, the y intercept is (0,0.5)
plugging this value in each equation:
y=1*4^x
plugging x as 0 and y as 0.5
lhs≠rhs
plugging x as 0 and y as 0.5
lhs = rhs
y= 1/2 x 4x

Answer:
D) y= 10*4^x
Step-by-step explanation:
Replace each function with x = 0
A)
B)
C)
D)
If you check the graph with x = 0, the value of y is between 8 and 12 so the only probably answer acoording to the alternatives is D) which gives y = 10 when x = 0
v² = 64
Take the square root of each side: v = √64 = +8 and -8 .
Answer:
proper answer pls
Step-by-step explanation:
<span>Using
the points (2, 45) (4, 143) and (10, 869), we can plug them into the
following system of 3 equations using the y = ax^2 + bx + c format:
45 = a(2)^2 + b(2) + c
143 = a(4)^2 + b(4) + c
869 = a(10)^2 + b(10) + c
which simplifies to:
45 = 4a + 2b + c
143 = 16a + 4b + c
869 = 100a + 10b + c
Solving the system, we get a = 9, b = -5, and c = 19. Thus the equation is:
c(x) = 9x^2 - 5x + 19
If you have a TI graphing calculator, you can also enter the points by
pressing Stat -> Edit and enter (2, 45) (4, 143) and (10, 869) into
it. Go back and calculate the QuadReg of the points from the Calc tab
and it will give you the same answer.
Now that we know the function that will produce the price of production
for any number of calculators, plug in x = 7 and it will give you the
price to produce 7 calculators.
c(x) = 9x^2 - 5x + 19
==> c(7) = 9(7)^2 - 5(7) + 19
==> c(7) = 441 - 35 + 19
==> c(7) = 425
Therefore, it costs $425 to produce 7 calculators.
Hope this helps.

Answer:
i think it would be multiplied by x
Step-by-step explanation:
that sounds like the best thing to do
