mark knows that his yard is 2 1/4 times as long as it is wide. which equation shows the length, in feet, of the fence that goes all the way around the yard if mark measures the width as w feet? 2 1/4 w feet

In a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. In one instance, the radius of the circle is 0.608 m. At one point on this circle,...

a certain radioactive element has a half life of 31.2 years. in how many years will contamination reach 32% of the original contamination?

the population of a city is given by 3000e^(kt), where t = 0 corresponds to the year 1960. in 1950 the population was 2400. Find k to the thousandth place, and predict the population in 2015.

You are skiing down a mountain with a vertical height of 1500 feet. The distance from the top of the mountain to the base is 3000 feet. What is the angle of elevation from the base to the top of the mountain?

thanks! is the rest of the paragraph alright?

b,c,c,d

It is C.

Isn't it just -1?

So the answer would be 51.168 years to get to 32% contamination?

@Jakob Sorry. I misunderstood it. I want to say the answer is 1 if you follow the pattern, and that i=-1, so -i = 1, but I'd wait for a teacher to help. Sorry if it didn't help.

@oobleck So I assume 1/10 is 1 year, but where does ln 1.25 come in from? If I follow correctly, you should end up with 600 = e^(-10k). Correct me if I made a mistake.

I understand now. I was doing 2400 - 3000. Had I don't division and followed through, I would have seen it. Thank you both!

I got 66.73 because tan^-1 (100/43)

Would it not be 2cm high? 7cm x 4cm = 28 cm. 56/28 = 2 cm.
