we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

t=5\ years\\ P=\$8,500\\ A=\$10,093.75\\r=?

substitute in the formula above

10,093.75=8,500*(1+r*5)

solve for r

5*r=(10,093.75/8,500)-1

r=0.0375

r=3.75\%

therefore

<u>the answer is</u>

the rate of interest is 3.75\%

She is wrong because she did the square root of 25 multiplied by 2, she should have just done the square root of 50.

For the second part the square root of 50 is 7.07 which rounding would equal 7.1.

Hope this helps.(ノ◕ヮ◕)ノ*:・゚✧

If t(n) = 15 - 2.5n, how do I find t1,t2,t3,and tn+1? I also have to express tn+1-tn in its simplest form.
Anvisha [2.4K]

Answer:

Just substitute, and the simplified form is 1

Step-by-step explanation:

Substitute the values needed into the original equation. For example, if n=1

t(1)=15-2.5(1)=15-2.5=12.5. Or, if tn+1 substitute f(tn+1)=15-2.5(tn+1) and simplify.

tn+1-tn in its simplest form is just 1, as tn and -tn cancel out to leave 1.
