Find the interest due on $600 at 9.5% for 120 days.

KATRIN_1 [288]

Answer:

Interest= $ 18.73

Step-by-step explanation:

Given : $600 at 9.5% for 120 days

To find : Find the interest due

Solution :

Simple interest formula $I=P\times r\times t$

Principle(P)=$600 , rate(r)=9.5%=0.095 , time (t)= 120 days

In years, 1 year = 365 days

1 day = $\frac{1}{365}$ year

120 days = $\frac{120}{365}$ year

Put values in the formula

$I=P\times r\times t$

$I=600\times 0.095\times\frac{120}{365}$

$I=\frac{6840}{365}=18.73$

Therefore, Interest= $ 18.73

If the line with the slope 5 that passes through the point (-1,3) intersects the x axis at a point, what are the coordinates of

Crazy boy [7]

Answer: (-8/5,0)

Step-by-step explanation: If the slope is 5, m = 5

For (-1,3) we have x₀= -1 and y₀ = 3, to find the line equation

y - y₀ = m(x - x₀)

y - 3 = 5(x - (-1))

y - 3 = 5(x + 1)

y - 3 = 5x + 5

y = 5x + 8

A P that intersects the x axis has y = 0

0 = 5x + 8

5x = -8

x = -8/5

P (-8/5,0)
