Answer:

Step-by-step explanation:

To find the amount deposited, we will simply use the formula for calculating simple interest.

Simple Interest = pxrxt/100     (fraction)

Where p = principal

      R= Rate

           T= Time

Principal is the initial amount deposited which we are ask to find.

R is given to be 6%  and T is the time which is given in years

Simple interest is the interest earned over the year which is given to be $400

Lets substitute our variable into the equation

Simple Interest = pxrxt/100    (fraction)

$400  = P × 6 × 3   /     100

$400 = 18p/100    (fraction)

We will then cross multiply

$40 000  =   18 P

To get  the value of P, we divide both-side of the equation by 18

4000/18 = 18p/18     (fractions)

$2222.22 =  P

P = $2222.22

First, rewrite 16/25 and 13/20 so that they have a common denominator.
Akimi4 [234]

Answer:

The answer to your question is 64/100 and 65/100

Step-by-step explanation:

Data

Common denominator of   16/25 and 13/20

Process

1.- Find the least common factor of 25 and 20.

                            25      20      2

                            25      10       2

                            25        5       5

                              5         1       5

                               1

   L.C.F. = 2 x 2 x 5 x 5 = 100

2.- Convert each fraction to the denominator 100

           100 / 25 = 4

            16/25 = (16 x 4) / 100

                     = 64/100

            100 / 20 = 5

            13/20 = (13 x 5)/100

                      = 65/100

4cos^2(x)-7cos(x)+3<br> Please help and explain how you did it :)
dangina [55]

I assume you're asked to solve

4 cos²(<em>x</em>) - 7 cos(<em>x</em>) + 3 = 0

Factor the left side:

(4 cos(<em>x</em>) - 3) (cos(<em>x</em>) - 1) = 0

Then either

4 cos(<em>x</em>) - 3 = 0   <u>or</u>   cos(<em>x</em>) - 1 = 0

cos(<em>x</em>) = 3/4   <u>or</u>   cos(<em>x</em>) = 1

From the first case, we get

<em>x</em> = cos⁻¹(3/4) + 2<em>nπ</em>  <u>or</u>   <em>x</em> = -cos⁻¹(3/4) + 2<em>nπ</em>

and from the second,

<em>x</em> = <em>nπ</em>

where <em>n</em> is any integer.

Add and simplify 3/14+9/14
Deffense [45]
This is relatively simple because both have the same common denominator. All you must do is add 3 and 9 together. That gives you 12/14. To simplify we can half both numbers down to 6/7.
Hope that helps !

HELP!!!! 3. Find the x-intercept of the graph of the linear equation y = 2x + 4.
Naily [24]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

(-2, 0)

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\text{Substitute in \textbf{0} for } y \text{ and solve for } x\text{.}\\-------------------\\y = 2x+4\\-------------------\\\rightarrow 0 = 2x +4\\\\\rightarrow 2x + 4 = 0\\\\\rightarrow 2x +4 - 4 = 0 - 4\\\\\rightarrow 2x = -4\\\\\rightarrow\frac{2x=-4}{2}\\\\\rightarrow \boxed{x=-2}

⸻⸻⸻⸻

\text{The \textbf{x-intercept} of the given equation is: } (-2, 0)

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
