The equation of a curve is y=f(x). the curve goes through the points (1,3) and (3,7). f'(x) = 4x+p, where p is a number.
Nimfa-mama [501]
f'(x)=4x+p\\
f(x)=2x^2+px+C\\\\
3=2\cdot1^2+p\cdot1+C\\
7=2\cdot3^2+p\cdot3+C\\\\
3=2+p+C\\
7=18+3p+C\\\\
C=1-p\\
3p=-11-C\\\\
3p=-11-(1-p)\\
3p=-11-1+p\\
2p=-12\\
p=-6\\\\
C=1-(-6)\\
C=7\\\\
y=2x^2-6x+7

what are the missing numbers?
crimeas [40]

Given:

The table of values of an exponential function.

To find:

The missing values in the exponential function.

Solution:

The general exponential function is defined as:

y=a(b)^x              ...(i)

Where, a is the initial value and b is the growth factor.

First point from the given table is (1,10). It means, the equation (i) must be true for (1,10).

10=a(b)^1             ...(ii)

Second point from the given table is (2,20). It means, the equation (i) must be true for (2,20).

20=a(b)^2             ...(iii)

Dividing (iii) by (ii), we get

\dfrac{20}{10}=\dfrac{a(b)^2}{ab}

2=b

Putting b=2 in (ii), we get

10=a(2)^1

\dfrac{10}{2}=a

5=a

Putting a=5,b=2 in (i), we get

y=5(2)^x

The required exponential function for the given table of values is y=5(2)^x. So, the missing values are 2 and x, where 2 is in the base and x is in the power.

What is the solution to the system of equations? you must show all work to recieve full credit!
earnstyle [38]
Use the substitution method:
2x - 6y = -12
x - 2y = -8
Then x = 2y - 8
Substitute in the first equation:
2(2y - 8) - 6y = -12
4y - 16 - 6y = -12
-2y = 4
y = -2
Now substitute y in one of the two equations given you prefer:
For example x-2*(-2) = -8
x + 4 = -8
x = -12
The solutions are x = -12 and y = -2
