Answer:
d) x-intercepts are –3 and –5; vertex is (–4, 1)
Step-by-step explanation:
parabola are the vertex findings -4
we find these using formula m +n / 2
m+ n = -3 -5 / 2 = -4
m+n / 2 = -8/2 = -4
xv = -4
plug in -4 to find yv
(x+5)
(-4 + 5)
yv = 1
Answer:
7 ft
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
153.86 = 3.14 r^2
Divide each side by 3.14
153.86 / 3.14 = r^2
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 = r
Answer:

Answer: Danny's supermarket
Step-by-step explanation:
Danny's price- 0.75x1.5= $1.12 for 1 liter water bottle
Marta's price- $1.50 for 1.25 liter water bottle
1.12x1.25=1.40, if Danny was selling a 25% bigger bottle(making the bottle size equal to Marta's) it would cost $1.40, the lower price
