A friend of yours claims to be able to ride a bicycle 20 feet per second, is this a reasonable
sp2606 [1]

Answer:

No and yes

Step-by-step explanation:

If the bike is at a sudden hault (A FULL STOP) its physically impossible for the sudden speed of his weight and laws of inertia to pull him forwar that quick.

NOW - if the bike is already in motion and going downhill the gravitational down force will haul his speed at 45MPH and would make him reach the lenght of 66feet per second.

The grizzly bear population in yellowstone national park in 1970 was about 270.Over the next 35 years,it increased by about 115%
yawa3891 [41]

Answer:

581

Step-by-step explanation:

<u>Population of Grizzlys</u>

1970   >>>   270

2005   >>>   115% INCREASE

We need to find 115% of 270 and increase 270 by that amount. Firstly, converting percentage to decimal (division by 100):

115/100 = 1.15

So, that would be now:

1.15 * 270 = 310.5

Increasing, we get:

270 + 310.5 = 580.5

We round to 581

In 2005, the population was about 581

The function f(x)=5(2)^x was replaced with f(x)+k , resulting in the function graphed below.
ella [17]
In this problem, you have to find the y- intercept of f(x)=5(2)^x. I graphed mine into a graphing calculator. An algebraic way to find it is to input x=0 in the function. The y-intercept is 5.  You can see the y-intercept for the new one is -2. That means we shifted the graph down 7 units. (Vertical Shift down 7)
