An increase is adding, not multiplying. they meant that 5 times a number is 500% of something. it would be a 400% increase as one plus four is five.

Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use th
Archy [21]

Answer:

  (a) 1 inch of rider ⇒ 0.29 inches of frame

Step-by-step explanation:

The "slope" in the equation is the coefficient of the independent variable. Here, that variable is "h", and its coefficient is 0.29. That is, the height of the rider is multiplied by 0.29 (and a constant is added) in order to find the height of the frame.

__

The meaning of the value 0.29 is that a 1 inch increase in the rider's height should result in a 0.29 inch increase in the height of the frame of the bike.

The question asks for an <em>explanation</em> of the slope, not its function in the equation. That is why we have chosen the first answer.

Assume: c = 40 + 0.8(y - t) g = 10 i = 20 t = 0, where t are taxes. (a) calculate y at equilibrium. (b) calculate c, i, and g at
Sonja [21]

(a). To calculate Y at equilibrium

Y = C + I + G

Y = 40 + 0.8(Y – 0 + 10 + 20)

Y = 350

 

(b). To calculate C, I and G at Equilibrium

C = 40 + 0.8 Y

Since Y = 350

C = 40 + 0.8(350)

C = 40 + 280

C = 320

I = 20

G = 10

 

(c).To find equilibrium Y

Given,

EX = 4 + 3EP/P

IM = 8 + 0.1 (Y - T) - 2EP/P

E = 3

P = 1

P = 1.5

Y = 170

I need help pls and I will give a 5 star rating and a big thank you comrades.
zhuklara [117]
Answer: B) y=6/11.

To find the horizontal asymptote(s) you must find the limit as x approaches infinity and the limit as x approaches -infinity.

Using L’Hôpital’s rule:
lim x-> infinity (f(x))=6/11.
lim x-> -infinity (f(x))=6/11.
