Answer:

boat: 6 mph
current: 2 mph

Step-by-step explanation:

The relationship between time, speed, and distance is ...

speed = distance/time

For boat speed b and current speed c, the speed downstream is ...

b +c = (16 mi)/(2 h) = 8 mi/h

The speed upstream is ...

b -c = (16 mi)/(4 h) = 4 mi/h

Adding the two equations eliminates the c term:

2b = 12 mi/h

b = 6 mi/h . . . . . divide by 2

Solving the second equation for c, we get ...

c = b -4 mi/h = 6 mi/h -4 mi/h = 2 mi/h

The speed of the boat in still water is 6 mi/h; the current is 2 mi/h.

Find the complete factored form of the polynomial -44a^3 + 20a^6

irakobra [83]

Answer:

$4a^3(5a^3-11)$

Step-by-step explanation:

→Take out the GCF (Greatest Common Factor). The GCF is $4a^3$ because both $-44a^3$ and $20a^6$ can be divided by it, like so:

$-44a^3+20a^6$

$4a^3(5a^3-11)$

A) P is the current value so P is $2,500.

r is the annual percentage rate which is 2.7% BUT it must be written as a decimal.

$\frac{100 + 2.7}{100} = 1.027$

so r is 1.027.

n is 4 because it is compounded quarterly which is 4 times per year.

B) now substitute these values into the formula and now you know that t is 7 as it says in the question

$2500 \times ({1 + \frac{1.027}{4} }^{7 \times 4} )$

when you type this into the calculator, you should round your answer to 2 decimal places as you are considering money.

therefore, the answer is $1,502,827.17

hope this helps! have a good day ~ •lipika•
