What is a quadratic function?

1 answer:

3 0

C - F(x)= 5x^2-4x+5

Quadratic function equations have an x raised to the second power and makes a parabola when graphed. B could potentially also be right depending on who you ask because x is being raised to the second power but since the equation says 0x it means there is no x to be raised to the second power so i would say C.

What value of b makes the polynomial x2+bc+16 a perfect square

Fynjy0 [20]

For a perfect square

b² = 4*a*c

Comparing ax² + bx + c = 0 to x² + bx + 16

a = 1, c = 16

b² = 4*a*c

b² = 4*1*16

b² = 64

b = √64

b = 8

The value of b = 8.

3 Fred is making a fruit salad. The ratio

marusya05 [52]

Answer: 24 cups.

Step-by-step explanation:

Let be "x" the amount of cups of peaches that Fred will need to make 60 cups of fruit salad.

According to the information given in the exercise, you know that the ratio of cups of peaches to cups of cherries is the one shown below:

$2:3$

Which can also be written as a fraction:

$\frac{2}{3}$

Then, if he uses 2 cups of peaches and 3 cups of cherries, he will get 5 cups of fruit salad.

Knowing the above, you can set up the following proportion:

$\frac{2}{5}=\frac{x}{60}$

Now you must solve for "x" in order to find its value. This is:

$(60)(\frac{2}{5})=x\\\\x=24$

Choose the correct simplification of the expression a^7b^8/a^4b^4

Alex787 [66]

The answer is B: a^3b^4

Proof:
Simplify the following:
(a^7 b^8)/(a^4 b^4)

Combine powers. (a^7 b^8)/(a^4 b^4) = a^(7 - 4) b^(8 - 4):
a^(7 - 4) b^(8 - 4)

7 - 4 = 3:
a^3 b^(8 - 4)

8 - 4 = 4:
Answer: a^3 b^4

PS: I just wish that you put the equation down as it's intended i.e.
a^7b^8/a^4b^4 is not the same as (a^7b^8)/(a^4b^4)
