Answer:
y= 12x-16
Step-by-step explanation:
Given that you have a slope of 12 and a point of (3, 20), you are most obligated to using the Slope-Intercept form, or y=mx+b.
What this allows you to find is the y-intercept if your line has one. You take your point, (3,20), and you insert the values at the appropriate places. You should now have 20=12(3)+b. You will then solve for b by multiplying 12 and 3 to get 36 and subtract that from both sides of the equal sign. You should have 20-36=b. 20-36 is -16, which is your y-intercept.

Bernie has $16000 invested, part at 3% and the remainder at 5%. If the yearly interest on each investment is the same, how much
Snowcat [4.5K]
If the interest is the same for both accounts then:

.03x=.05(16000-x)

.03x=800-.05x

.08x=800

x=10000, since the interest is the same for both we can just double the interest from one investment to find the total interest earned each year...

.03(10000)2=$600.00

A small block is pulled along a rough horizontal surface at a constant speed 2 ms by a constant force. This force as magnitude 2
levacccp [35]

The work done by the force in 10 seconds is 250 Joules

<h3>Workdone definition?</h3>

This is the product of force and distance covered by a body

The formula for calculating the workdone is expressed as:

  • W = Fdsin theta

From the information given

Workdone = 25* (2*10) sin 30

Workdone = 500(0.5)

Workdone = 250 Joules

Hence the work done by the force in 10 seconds is 250 Joules

A deposit earns interest at a rate of r percent compounded continuously and doubles in value in 9 years. Find r. (Round your ans
AVprozaik [17]

Answer:

The earning rate is approximately 0.08.

Step-by-step explanation:

We can determine the yearly rate by means of compound interest, which is defined by:

C(t) = C_{o}\cdot (1+r)^{t} (Eq. 1)

Where:

C_{o} - Initial deposit, measured in US dollars.

r - Earning rate, dimensionless.

t - Earning periods, measured in years.

We proceed to clear the earning rate within:

\frac{C(t)}{C_{o}} = (1+r)^{t}

\log \frac{C(t)}{C_{o}} = t\cdot \log (1+r)

\frac{1}{t}\cdot \log \frac{C(t)}{C_{o}} = \log (1+r)

\log \left(\frac{C(t)}{C_{o}} \right)^{\frac{1}{t} } = \log (1+r)

\left(\frac{C(t)}{C_{o}} \right)^{\frac{1}{t} } = 1+r

r = \left(\frac{C(t)}{C_{o}} \right)^{\frac{1}{t} }-1

If we know that C(9) = 2\cdot C_{o} and t = 9, then the earning rate is:

r = 2^{\frac{1}{9} }-1

r \approx 0.08

The earning rate is approximately 0.08.
