Answer:
B
Step-by-step explanation:
using the tangent ratio on the triangle on the right and the exact value
tan60° = , then letting the altitude be h
tan60° = = = ( multiply both sides by h )
11 = h × ( divide both sides by )
11 = h
using the sine ratio in the triangle on the left and the exact value
sin45° = , then
sin45° = = = = ( cross- multiply )
× x = 22 ( divide both sides by )
x = 22
Answer: Area of ΔABC is 2.25x the area of ΔDEF.
Step-by-step explanation: Because equilateral triangle has 3 equal sides, area is calculated as
with a as side of the triangle.
Triangle ABC is 20% bigger than the original, which means its side (a₁) measures, compared to the original:
a₁ = 1.2a
Then, its area is
Triangle DEF is 20% smaller than the original, which means its side is:
a₂ = 0.8a
So, area is
Now, comparing areas:
2.25
<u>The area of ΔABC is </u><u>2.25x</u><u> greater than the area of ΔDEF.</u>
A) In Part 1 to part 2 the bus had its farthest distance. At part 2 the bus stayed steady time went by. Part 3 to 4 was decreasing distance. part 4 was constant. Then again at part 5 the distance was increasing
B)
1 - increasing
2 - constant
3 - decreasing
4 - constant
5 - increasing
C) Non-linear, because the graph has a curve, for it to be linear it must be a straight line.
