How much interest is earned on a principal of $2.58 invested at an interest rate of 5% for four years?

pochemuha

Answer:

Step-by-step explanation:

The formula for simple interest is

prt = I, where p is the initial investment, r is the interest rate in decimal form, t is the time it's invested for, and I is the interest earned. We multiply the p, the r, and the t together to get I. For us that looks like this:

(2.58)(.05)(4) = I and

I = .516 or 52 cents.

An electrician charges $35 per hour plus a fixed amount for residential work. For a job that took 6 hours, he billed $270. Write

Alexeev081 [22]

With the information provided, we can begin with the equation:

y=35x + b

With x = number of hours, y = total cost, b = fixed amount that is charged for residential work

We know that after 6 hours, $270 was charged:

$270 = $35(6) + b

Solve for b:

b = $270 - $210 = $60

The fixed amount that is charged for residential work is $60. So now we can rewrite the equation as:

y = 35x + 60

What is the radius of a circle whose equation is X^2 plus Y^2 -10X +6 X +18=0?

frosja888 [35]

ANSWER

The radius is 4

EXPLANATION

The given equation is:

${x}^{2} + {y}^{2} - 10y + 6x + 18 = 0$

We complete the square to get the expression in standard form:

${x}^{2} + 6x + {y}^{2} - 10y + 18 = 0$

${x}^{2} + 6x + 9 + {y}^{2} - 10y + 25 = - 18 + 9 + 25$

We factor using perfect squares to get:

${(x + 3)}^{2} + {(y - 5)}^{2} = 16$

This implies that,

${(x + 3)}^{2} + {(y - 5)}^{2} = {4}^{2}$

Comparing to

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

The radius is r=4

Evaluate x+y when x=13 and y=−74. Write your answer as a fractionin simplest form

Fofino [41]

<u>The value of the expression is -35.</u>

<u>Step-by-step explanation:</u>

<u>Consider the provided expression.</u>

<u>3x + y </u>

<u>We need to find the value of the expression for x=13 and y=−74 .</u>

<u>Substitute the value of x=13 and y=−74 in the above expression as shown:</u>

<u>3 (13) + (-74)</u>

<u>39 - 74 </u>

<u>-35</u>

<u> the value of the expression is -35.</u>
