If you weighed 105 kg on Earth, you would weigh 17.36 kg on the Moon (Rounded would be 17.4).

If 800g of a radioactive substance are present initially and 8 years later only 450g remain, how much of the substance will be p

artcher [175]

A=Pe^(rt)

P = 800g

t = 8 years

A = 450g

r = This is what we will try and find to start with

450=800e^(r*8)

After running the math through a calculator, we end with r = -0.07192

Now we just re-input this information into our equation: A=800e^(-0.07192*16)

A=800e^(1.15072)

Now we will re-write the equation using the negative exponent rule:

A = 800 1/e^1.15072

Combine right side:

A = 800/e^1.15072

Then do the math:

A = 253.12709836......

That will give us A = 253 (rounded to the whole number)

I hope this helps! :)

The table below represents the displacement of a turtle from its nest as a function of time: Time (hours) x Displacement from ne

andriy [413]

Part A: The y-intercept is 5. If you look to the data, when x=0, y=5. This means that the turtle started off 5 miles away from its nest. (at 0 hours, the distance away from his nest was 5 miles)

Part B:Answer=22. Remember, if you take any two distinct points on a line, the slope of the line will be equal to the average rate of change. In short, we're just looking for the slope between the ordered pairs (1,27) and (4,93). The formula for slope is:

$slope= \frac{y_{2}- y_{1} }{ x_{2} - x_{1} } = \frac{93-27}{4-1}= \frac{66}{3}=22$

The average rate of change between x=1 and x=4 is 22. The average rate of changed describes the rate at which miles is changing with respect the the change in hour.

Part C: Answer=10hours. Since by now we know both the slope and the y-intercept, lets write the equation in slope intercept form and then solve for 225 miles.

y=mx+b
y=22x+5
225=22x+5
subtract 5 from both sides
220=22x
divide both sides by 22
10=x
It would take 10 hours for the turtle to travel 225miles from it's nest.

A motorcycle insurance company has 5,000 policy holders, and the accident rate is 0.08. the company needs to invest $400,000 thi

Oksi-84 [34.3K]

When the insurance company want a plan with a deductible of $4,000, they need to charge a minimum of $18000 for premiums.

<h3>What is a deductible?</h3>

It should be noted that a deductible simply means the amount of money that is paid out of the pocket of the policy holder.

From the information given, each accident costs $18,000 on average. Therefore, this is the minimum amount of premium.

When they want a plan with a premium of $1,000, the amount that they'll need to charge for deductibles will be:

= (4000/18000) × 1000

= $220
