<span>∠C ≅ ∠F
</span>
The first statement is incorrect, as none of the sides are congruent.
The second statement is incorrect, because angle A is congruent to angle D, not similar.
The third statement is incorrect, because AC corresponds to DF, not DE.
Answer:
The length of each edge is 2in.
Step-by-step explanation:
This is because 2x2x2=8. 2x2 is 4 and 4x2 is 8.
Answer:
Step-by-step explanation:
The independent variable always goes on the x-axis, or the horizontal axis. The dependent variable goes on the y-axis, or vertical axis. Here's an example: As you can see, this is a graph showing how the number of hours a student studies affects the score she got on an exam
Step-by-step explanation:
A) A is 100*10% of B
A is 1000% of B
B) A is (8/1.5)*100% of B
A is 5.33*100% of B
A is 533% of B
Height of the woman = 5 ft
Rate at which the woman is walking = 7.5 ft/sec
Let us assume the length of the shadow = s
Le us assume the <span>distance of the woman's feet from the base of the streetlight = x
</span>Then
s/5 = (s + x)/12
12s = 5s + 5x
7s = 5x
s = (5/7)x
Now let us differentiate with respect to t
ds/dt = (5/7)(dx/dt)
We already know that dx/dt = 7/2 ft/sec
Then
ds/dt = (5/7) * (7/2)
= (5/2)
= 2.5 ft/sec
From the above deduction, it can be easily concluded that the rate at which the tip of her shadow is moving is 2.5 ft/sec.
