Inquashia took out a 2900 loan for a car the interest on the loan is a 8% compounded monthly how much in total will in Isha and
Shtirlitz [24]

Answer: the total amount after 6 years is 4690

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount of the loan at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount loaned.

From the information given,

P = 2900

r = 8% = 8/100 = 0.08

n = 12 because it was compounded 12 times in a year.

t = 6 years

Therefore,

A = 2900(1 + 0.08/12)^12 × 6

A = 2900(1 + 0.0067)^72

A = 2900(1.0067)^72

A = 4690

Answer:

<h2>39.94 cm</h2>

Solution,

ABCD is a rectangle.

Given,

AC= 64 cm

AB= 50 cm

To find: Value of other side of TV

since, ABCD is a rectangle

<B= 90°

<h3>Using Pythagorean theorem:</h3>

{ac}^{2}  =  {ab}^{2}  +  {bc}^{2}  \\  {64}^{2}  =  {50}^{2}  +  {bc}^{2}  \\  {bc}^{2}  =  {64}^{2}  -  {50}^{2}  \\  {bc}^{2}  = 4096 - 2500 \\  {bc}^{2}  = 1596 \\ bc =  \sqrt{1596}  \\ bc = 39.94 \: cm

Hope this helps...

Good luck on your assignment..

Based on experimental data, the function T(x) = -3(x − 4)^3 + 10 models the temperature of a special substance after being place
Ainat [17]

I can't say for sure this answer is 100% correct because I think more info is needed.

If your teacher is looking for the turning point, then that would be (4,10)

The equation y = a(x-h)^3 + k has a turning point at (h,k). The parent function y = x^3 gets shifted h units to the right (assuming h is positive) and k units up (if k is positive). In this case, (h,k) = (4,10) so we have y = a(x-4)^3 + 10. The original turning point (0,0) has been shifted to the new turning point (4,10) which is 4 units to the right and 10 units up. The value of 'a' does not effect the turning point.

If x was say the time in minutes and y was the temperature, then the turning point of y = -3(x-4)^3 + 10 could mean that at time 4 minutes (x = 4) the substance turns from liquid to solid (y = 10 degrees).

Note: more information is needed about this function be 100% certain about the claim made.
