The rate at which an assembly line workers efficiency E (expressed as a percent) changes with respect to time t is given by E'(t

zavuch27 [327]

By the fundamental theorem of calculus,

$E(t)=E(1)+\displaystyle\int_1^t E'(u)\,\mathrm du$

So we have

$E(t)=92+\displaystyle\int_1^t(75-6u)\,\mathrm du$

$E(t)=92+(75u-3u^2)\bigg|_1^t$

$E(t)=20 + 75 t - 3 t^2$

Kayla needs $14,000 worth of new equipment for his shop. He can borrow this money at a discount rate of 10% for a year.

arlik [135]

Answer:

$15400

Step-by-step explanation:

Principle amount, P = $14000

Time, T = 1 year

Rate of interest, R = 10%

We know that maturity amount,

$A = P\left (1+\frac{R}{100} \right )^{n}$

where n is number of years

$A = P\left (1+\frac{R}{100} \right )^{n}$

$A = 14000\left (1+\frac{10}{100}\right )^{1}$

$A = 14000\left (1+\frac{1}{10}\right )$

$A = 14000\left (\frac{11}{10}\right )$

$A = 15400$

The maturity amount is $15400

Pls help asap so confused!!!!<br><br> What is the distance??

Vesnalui [34]

Answer:

6.3

Step-by-step explanation:

You can find the distance with a distance formula (need the points and it has a big, long square root) BUT, when you have an image like this graph you can totally see a right triangle and use the Pythagorean Theorem (distance formula is derived from Pythagorean theorem anyway) see image
