Subsitute 1 forx
f(1)=(3(1)+7)^2
f(1)=(3+7)^2
f(1)=10^2
f(1)=100

To find f(1), substitute 1 for x.

f(1) = (3(1)+7)²
f(1) = (3+7)²
f(1) = 10²
f(1) = 100

Which equation represents a quadratic function?

Elena-2011 [213]

Quadratic is where the degree of x is 2
I would think 3 is the one that might have been written as y=x² which would be correct

Pam and Meg each have a picture frame. Pam’s picture frame is a square with an area of 3 square feet. Meg’s picture frame is a c

kondaur [170]

Answer:

The circumference of Meg’s picture frame is the perimeter of Pam’s picture frame by approximately 0.65 ft

Step-by-step explanation:

Pam's picture frame : Square with area of 3 sq. foot

Meg’s picture frame is a circle with a radius, r of 1 foot.

The circumference of Meg’s picture frame is the perimeter of Pam’s picture frame by approximately feet.

Let's calculate circumference of Meg's picture frame:

Circumference c, = 2πr

r = 1 ft

c = 2 * 3.14 *1 = 6.28 ft

Now calculate Perimeter of Pam's picture frame:

A is area of square and s is the side

A = s²

s² = 3

s = √3

Permeter of square = 4s

= 4√3 = 6.93ft

Now in order to find circumference of Meg’s picture frame is the perimeter of Pam’s picture frame, we have to find their difference.

Permimeter of square frame - Circumference of circle frame = 6.93 - 6.28 = 0.65
