The simple interest I on an investment of P dollars at an interest rate r for t years is given by I=Prt. Find the time it would
Darina [25.2K]

we know that

I=Prt

where

I is the amount in interest

P is the investment

r is the interest rate

t is the time in years

Solve for t

t=I/(Pr)

we have

I=\$1,400\\ P=\$27,000\\ r=4.2\%=0.042

substitute

t=1,400/(27,000*0.042)=1.23\ years

therefore

<u>the answer is</u>

1.23\ years

40 POINTS- Are a logistic equation and a logistic regression model the same thing? If not, what's the difference?
pychu [463]

Answer: They are diffrent

Step-by-step explanation: The logistic equation was first published by Pierre Verhulst in 1845. This differential equation can be coupled with the initial condition P(0) = P0 to form an initial-value problem for P(t). Suppose that the initial population is small relative to the carrying capacity. Then P K is small, possibly close to zero.

The logistic regression coefficients are the coefficients b 0, b 1, b 2,... b k of the regression equation: An independent variable with a regression coefficient not significantly different from 0 (P>0.05) can be removed from the regression model (press function key F7 to repeat the logistic regression procedure).

By the way, this is copied from the internet.

Find the compound interest when principal =2000 rate =20%per annum and time 3 years ​
lbvjy [14]

<h2>Question:-</h2>

  • Find the compound interest when
  • principal =2000
  • rate =20%per annum
  • and time 3 years.

<h2>To find:-</h2>

  • Compound interest

<h2>Given:-</h2>

  • Principal = Rs.2,000
  • Rate = 20%
  • Time = 3 years.

<h2>Solution:-</h2>

⇒A = P (1 + \dfrac{R}{100} )^{n}

=2000 (1 + \dfrac{20}{100})^{3}

 = 2000 ( 1 + \dfrac{1}{5} )^{3}

 = 2000 (\dfrac{6}{5}) ^{3}

 = 2000 \times\dfrac{6}{5} \times \dfrac{6}{5} \times \dfrac{6}{5}

= 16 × 6 × 6 × 6

⇒A = Rs.3456

⇒CI = A - P

⇒CI = 3456 - 2000

⇒CI = Rs.1456

Answer:-

·Compound interest is Rs.1456.

Which represents the inverse of the function f(x) = 4x?
Nataly [62]

Answer:

h(x)=1/4x

Step-by-step explanation:

Inverse function is when the domain and range of a function are swapped, or in other words the y and x values are swapped.

To do this you simply change x to y, and y to x in the equation

So we have the original equation

y = 4x

swap y and x

x = 4y

now solve for y by dividing by 4

y = x/4

which can also be expressed as h(x)=1/4x
