A man borrowed $3700 from a bank for 6 months. A friend was co-signer of the mans personal note. The bank collected 8.5% simple

Tpy6a [65]

Answer:

(A) $157.25

(B) $3,857.25

Step-by-step explanation:

The given values are:

Principle (P)

= $3700

Time (T)

= 6 months i.e., 1/2 years

Rate (R)

= 8.5%

(A)

As we know,

Simple Interest,

⇒ $SI=\frac{P\times R\times T}{100}$

On putting the values, we get

⇒ $=\frac{3700\times 8.5\times \frac{1}{2} }{100}$

⇒ $=\frac{15,725}{100}$

⇒ $=157.25$ ($) (he paid for the use of money)

(B)

Amount he paid to the bank will be:

⇒ $P+SI$

⇒ $3700+157.25$

⇒ $3,857.25$ ($)

If f(x) and it’s inverse function, f^-1(x), are, both plotted on the same coordinate plane, what is their point of intersection

Korolek [52]

Answer:

Step-by-step explanation:

Hello,

there is not always an intersection point

let's take the example of on the appropriate domain

$f(x)=e^x \ \ \ f^{-1}(x)=ln(x)$

there is no intersection point

if there is one it means that the point (x,f(x)) and the point (x, $f^{-1}(x)$ ) is the same so that have to solve

$f(x)=f^{-1}(x)$

for instance if we take

$f(x)=x^2 \ \ \ f^{-1}(x)=\sqrt{x} \ \ \ for \ x >= 0$

intersection point are for x >= 0

$x^2=\sqrt{x} x^4=xx^3=1 \ or \ x=0 x = 1 \ or \ x=0$

hope this helps

Your plan was to be on the road by 9 A.M. but you did not leave the garage until 10 A.M. You then drove with the cruise control

Wittaler [7]

Answer:

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.

Step-by-step explanation:

The average speed is given by the following equation:

$v = \frac{d}{t}$

From 10A.M. to noon.

You traveled at 50mph during 2 hours. So how long you traveled?

$50 = \frac{d}{2}$

$d = 50*2$

$d = 100$

You traveled 100 miles.

What was your average speed over the time interval from 9 A.M. to noon

From 9 A.M. to 10 A.M, you did not travel.

From 10 P.M. to noon, 100 miles.

So 100 miles during 3 hours.

$v = \frac{d}{t} = \frac{100}{3} = 33.33$

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
