Celina measured the height of a window frame as 5.55 feet, but the actual height was 6 feet. What is the percentage of error in

iVinArrow [24]

1) 6 - 5.55 = 0.45 feet (the difference between 6 and 5.55)
2) 0.45/6 * 100 = 7.5% (the percentage of error in Celina's measurement)

You must divide the diameter of Mars by the diameter of softball.

$(7\times10^7):(0.098)=\dfrac{7\times10^7}{0.098}=\dfrac{7\times10^7:7}{0.098:7}=\dfrac{10^7}{0.014}\\\\=\dfrac{10^7}{\frac{14}{1000}}=10^7\times\dfrac{1000}{14}=\dfrac{10^7\times10^3}{14}=\dfrac{10^{7+3}}{14}=\dfrac{1}{14}\times10^{10}\\\\\dfrac{1}{14}\approx0.071\to\dfrac{1}{14}\times10^{10}\approx0.071\times10^{10}=0.071\times10^2\times10^8\\\\=7.1\times10^8\\\\\text{Used}\ a^n\times a^m=a^{n+m}$

A parabola opening upward shifted 7 units rights and 4 units down

Sati [7]

Answer:

y + 4 = a(x - 7)^2

Step-by-step explanation:

The standard vertex form of a parabola with vertex at (h, k) is

y - k = a(x - h)^2

and if we start with the simplest case, y = a(x)^2 and translate its graph 7 units to the right and 4 units down, we get y - {-4] = a(x - 7)^2, or

y + 4 = a(x - 7)^2
