Answer:
Ok so I've had braces and it doesn't really hurt getting put in but it does hurt when they tighten them but you have nothing to worry about :)
Step-by-step explanation:
To calculate the rate of change, one must divide the total change by the amount of time that it took, in this case years. One can find the total change by subtracting the two quantities, $15,200 and $8,000. This gives a rate of change of $7,200 per four years. To find the change per year, one must do what I said in the first sentence, divide the total change by the amount of time. Doing this, one gets $1,800 changed per year, assuming there was a constant rate of change.
Step-by-step explanation:
the answer is 6/8 = y/16
you had it right the first time rise over run is simple
the up divided by the over
rise (the y intercept ) divided by the run (the x intercept)
-please correct me if if I got it wrong
Answer:
u know that if you see a check mark on a answer, it means that its right
Step-by-step explanation:
Answer:
the length of his shadow on the building is decreasing at the rate of 0.525 m/s
Step-by-step explanation:
From the diagram attached below;
the man is standing at point D with his head at point E
During that time, his shadow on the wall is y = BC
ΔABC and Δ ADE are similar in nature; thus their corresponding sides have equal ratios; i.e
8y = 24
y = 24/8
y = 3 meters
Let take an integral look at the distance of the man from the building as x, therefore the distance from the spotlight to the man is 12 - x
∴
To find the derivatives of both sides ;we have:
During that time ;
and y = 3
So; replacing the value into above ; we have:
Thus; the length of his shadow on the building is decreasing at the rate of 0.525 m/s
