Answer: 172 square meter square
Step-by-step explanation:
Area of Rectangular prism is given as :
A = 2 (wl + hl + hw)
Where :
w = width
h = height
l = length
Calculating the area of rectangular prism given , the shape given is divided into six segments , each segment is a triangle , all we need to do is to find the area of each segment and add.
Area of the first segment = 7 x 8 = 56 ( there are 7 boxes horizontally and 8 boxes vertically)
second segment = 2 x 8 = 16
third segment = 7 x 8 = 56
fourth = 2 x 8 = 16
fifth = 2 x 7 = 14
sixth segment = 2 x 7 = 14
Therefore , area of the rectangular prism will be
A = 56 + 16 +56 + 16 + 14 + 14
A = 172
profit on the twenty-five $50 radios
= 25*(50*0.08)=$100
Loss on the six $30 radios
= 6*(30*0.15) = $27
Combined result of both transactions
= $100-27
=$73 (profit)
Answer:
Option 3
Step-by-step explanation:
tan33°=x/7
x=4.5
4.5^2+7^2=y^2
20.25+49=y^2
y=√69.25
y=8.3
Step-by-step explanation:
y = 16x²
you put the x values one after the other in place of x and do the calculations.
x = -4
y = 16×(-4)² = 16×16 = 256
x = -3
y = 16×(-3)² = 16×9 = 144
x = -2.5
y = 16×(-2.5)² = 16×6.25 = 100
x = -2
y = 16×(-2)² = 16×4 = 64
x = -1.5
y = 16×(-1.5)² = 16×2.25 = 36
x = -1
y = 16×(-1)² = 16×1 = 16
x = -0.5
y = 16×(-0.5)² = 16×0.25 = 4
x = 0
y = 16×0² = 16×0 = 0
x = 0.5
y = 16×0.5² = 16×0.25 = 4
x = 1
y = 16×1² = 16×1 = 16
and so on.
36, 64, 100, 144, 256
as you can see, the y values are the same for the positive and the negative values.
because squaring a negative number is the same as squaring the same positive number. that is, because (if you remember) squaring something means to multiply that something with itself. and minus multiplied by minus is plus, as plus multiplied by plus is plus.
and that creates the symmetry around the y-axis or x = 0. everything left of the y-axis is mirrored on the right side of the y-axis (and vice versa).
Center is 7,10
Radius is 11
