What annual rate of interest would you have to earn on an investment of $3500 to ensure receiving $273.00 interest after 1 year?

kogti [31]

To find the answer, we will have to find the percentage of $273 to $ 3500, and we can use the formula:

$\frac{interest received}{investment amount} \times 100%$

In this case:

273/3500 x 100%

=39/500 x 100%

=7.8%

Therefore the annual interest rate would be 7.8%.

Hope it helps!

7y^2+15x-22. Y=4. ×=5

Nutka1998 [239]

let's plug the value of x and y as 5 and 4 respectively to find the value of given expression :

$7 {y}^{2} + 15x - 22$

$7(4) {}^{2} + (15 \times 5) - 22$

$(7 \times 16) + 75 - 22$

$112 + 53$

$165$

HELP PLEASE <br><br> how do i put this into a piecewise function?

Nonamiya [84]

Answer:

Step-by-step explanation:

2 functions start by making a domain

Function 1: -3≤x<1

Function 2: -1≤x≤1

Now come up with equations

Function 1= x+3

Function 2= 5

Now put it all together

f(x)= x+3 for -3≤x<1 and 5 for -1≤x≤1

HELP ASAP WITH THIS QUESTION

alexgriva [62]

Hey there (again)

$x = 2y \\ y = -2 \\ x = 2(-2) \\x= -4 \\ \\ \\ w + xy + 4x^2 = 2\\ w+-4(-2) + 3(-4)^2 = 2 \\ w + 8 + 3(16) = 2 \\ w + 8 + 48 = 2 \\ Subtract56: w + 56 =2 \\ 56 - 56 (Cancel) \\ 2 - 56 = -54 \\ w = -54$

Answer: $B$ the simplification performed in step 2 is invalid or incorrect

Good luck on your assignment and enjoy your day
