An account earns simple interest. $1800 at 6.5% for 30 months Find the interest earned.

1 answer:

4 0

Okay. The formula for simple interest is prt. You multiply the principal (initial amount) by the rate (percentage) by the time (months or years). $1,800 is the principal and 6.5% is the percentage rate. 1,800 * 6.5% (0.065) is 117. You earn $117 in interest annually. The time period is 30 months. There are 12 months in 1 year. Divide the amount of months by 12 to put it in a decimal. 30/12 is 2.5. Now, multiply 117 by 2.5 to find the total amount of interest earned. 117 * 2.5 is 292.5. There. The total amount of interest earned is $292.50.

Answer:

A is one of the true statements because 25 is the largest number that 50 and 75 can both divide evenly into.

D is the other true statement because 45 is the lowest number that 5 and 9 can both multiply into.

What is the range of the function g(x) = –3sec(2x + 4) – 1?

Jet001 [13]

The range of the function g(x) will be (–∞, –4] ∪ [2, ∞). Option C is correct.

<h3>What is the difference between domain and range?</h3>

The domain denotes all potential x values, while the range denotes all possible y values.

When we plot the graph of the given function we will get the maximum and the minimum value till we get the function plot. The difference in the value of those coordinates is the range of the function.

The range of the function g(x) will be (–∞, –4] ∪ [2, ∞).

Hence option C is correct.

20 POINTS !!!!<br> The roots of the equation x^2+bx+c=0 are −4 and 2. Find b.

Irina18 [472]

first, love the killua profile picture ! i love hunterxhunter i am currently on season 5, episode 44 or 45 aka 119 or 120 but anyways,

answer:

b = 2

step-by-step explanation:

because its roots are -4 and 2,

and a = 1 [The coefficient of $x^2$ ] we know that $x^2 + bx + c = (x - (-4)) (x-2)=(x+4)(x-2) = 0.$

using the distributive property we get,

$x^2 + 2x - 8 = 0.$

by equating coefficients (common strategy for partial fractions and undetermined coefficient method of solving ODE), we get b = 2 and c = -8 ( solved c just for fun guess :) ) .

hope this helps :)
