Answer:

y= -4x^2 + 15x - 14

Step-by-step explanation:

A parabola is always in the form y = ax^2 + bx + c.

Substitute each point to produce different equations:

-14 = 0a + 0b + c = c

so c = -14

-3 = a1^2 + b1 + c = a + b - 14

so a + b = 11

0 = a2^2 + b2 + c = 4a + 2b -14 = 0

so 4a + 2b = 14

if we double a + b = 11 we get 2a + 2b = 22

Subtract this from 4a + 2b = 14 and we get 2a = -8 so a= -4 and b = 11 - a = 15

We don't need to use the (3,5) points as we have all the information we need.

The perimeter of a rectangle is found by using the formula P = 2l + 2w, where P is the perimeter, l is the length and w is the w

velikii [3]

Answer:

#1: 11 cm

#2: 16.5 in

#3: 2.5 feet

Step-by-step explanation:

$P=2l+2w$ Solve for width by substracting 2l on both sides to isolate 2w

$P-2l=2w$

$2w=P-2l$

Replace.

$2w=26-2(2)\\2w=26-4\\2w=22\\w=\frac{22}{2}\\ w=11cm$

----------------------------------------------------------------------------

$P=2l+2w$

$P=2(3.5)+2(4.75)\\P =7+9.5\\P=16.5in$

----------------------------------------------------------------------------

$P=2l+2w$

Solve for l

$2l=P-2w\\2l=7-2(1)\\2l=7-2\\2l=5\\l=\frac{5}{2}\\ l=2.5feet$
