Jane invests £1,200 in a bank account which earns interest at the rate of 6% per annum.
Find the value of a) the investment after 5
years

£1560

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 1200 × 0.06 × 5 = 360

I = £ 360.00

The simple interest accumulated

on a principal of £ 1,200.00

at a rate of 6% per year

for 5 years is £ 360.00.

x=30

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
