Answer: The answer is C. 200

Step-by-step explanation:

I ~can ~see ~that ~it ~does~ not ~appear ~to ~be LINEAR

y = 73e^kx < ---~pulse~rate

.7 when y = 155 < ---~sub ~in ~x

155 = 73 e^(.7 * k)

ln ( 155/73)  =  .7k

.75296567  = .7k

k = 1.07567

for x = 0.9 : pulse rate  =  y = 73 e^(1.07567 ^. .9)  = ~ 192

Therefore~your~answer~is:~C.~200

Select the correct answer.
scoundrel [369]

Answer:

Option C

Step-by-step explanation:

Difference of the two expressions has been written as,

\frac{3x}{x^2-7x+10}-\frac{2x}{3(x-5)}

To rewrite this expression as one expression,

First he factored the the denominators,

\frac{3x}{(x-2)(x-5)}-\frac{2x}{3(x-5)}

Then Juan will make the denominators of both the terms equal,

For which he will multiply the second expression by \frac{x-2}{x-2}.

\frac{3x}{(x-2)(x-5)}-\frac{2x(x-2)}{3(x-5)(x-2)}

Option C will be the correct option.
