Answer: A. 184.8ft2
Step-by-step explanation:
The pyramid is made up of four sides that are rectangular, each side has a height of 12.4ft and base length of 6ft.
The base area is a square of 6ft by 6ft.
For the sides, area of a triangle is 1/2 x base x height
= 1/2 x 6 x 12.4 = 37.2m2
For the four triangles = 4 x 37.2 = 148.8m2
For the square base, area is 6 x 6 = 36m2
Total surface area = 148.8 + 36 = 184.8ft2
Median = 75 because that is where the middle line of the box is.
First quartile = 70 because that is what the left edge of the box represents.
Third quartile = 85 because the right edge of the box indicates that.
Maximum = 100 because at the far right is the maximum data point of your data set.
The middle 50% of that data is between 70 and 85 because those are the values the box covers. It goes from the first quartile, 70, and stretches all the way to the third quartile 85.
Answer:
18
Step-by-step explanation:
I2=h2+r2
25(2)=h2+7(2)
50=h2+14
-14 -14
36=h2
÷2 ÷2
18=h
In a quadratic function, y = a(x²) the smaller the coefficient "a", the larger is the parabola:
From widest to narrowest:
1) y=1/3x² (Widest)
2) y= -1/2x² (Wider)
3) y=-9x² (narrowest)
A=4
The work behind it
-11a+33= -11
-33 -33
-11a=-44
Divide both sides by -11
-44/-11=a
A=4
