£600 is invested into a savings account paying 5% compound interest per year. How much is in
the account after three years

£694.575

Step-by-step explanation:

Using the formula for calculating the compound interest expressed as;

A = P(1+r)^t

P is the principal = £600

r is the rate = 5% = 0.05

t is the time = 3 years

Substitute into the formula;

A = 600(1+0.05)^3

A = 600(1.05)^3

A = 600(1.157625)

A = 694.575

hence the amount in the account after 3 years is £694.575

what graph

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
