When we do this, the base of the parallelogram has length b 1 + b 2, and the height is the same as the trapezoids, so the area of the parallelogram is (b 1 + b 2)*h. Since the two trapezoids of the same size created this parallelogram, the area of one of those trapezoids is one half the area of the parallelogram
Answer:
a)
b) 0.09
Step-by-step explanation:
We are given the following in the question:
where B(t) gives the brightness of the star at time t, where t is measured in days.
a) rate of change of the brightness after t days.
b) rate of increase after one day.
We put t = 1
The rate of increase after 1 day is 0.09
Answer: C and D
Explanation:
Is it A? No, because a right triangle does not have all three sides with equal length. Only in a equilateral triangle will have all three equal sides of equal length.
Is it B? No, because a triangle has ZERO parallel lines. Remember parallel lines are like this | | in a triangle the lines are like this /\
Is it C? Yes, because a triangle has two sides of equal length, meaning it has two congruent sides.
Is it D? Yes, a right triangle has two sides that create the 90 degrees making it a right triangle. Perpendicular means that theirs two lines creating the 90 degree and a triangle has two perpendicular sides.
Answer:
5, 1 , -3 ,-7
Step-by-step explanation:
When x = -1
y = - 4 * (-1) + 1
= 4 + 1
= 5
When x = 0
y = - 4 * 0 + 1
= 0+ 1
= 1
When x = 1
y = - 4 *1 + 1
= - 4 + 1
= - 3
When x = 2
y = -4 * 2 + 1
= - 8 + 1
= - 7
