Answer:

c=8.1

Step-by-step explanation:

a^2+b^2=c^2

7^2+4^2=c^2

49+16=c^2

\sqrt{65}=\sqrt{c^2}

8.06=c

The formula used to calculate the value of a savings accounty =(1+)120What does theafter t years is A(t)=0.04= 1500 1+120.04frac
yulyashka [42]

We have here the formula for Compound Interest:

A=P(1+\frac{r}{n})^{nt}

Where:

• A is the accrued amount.

,

• P is the Principal (the original amount of money, the starting amount of money).

,

• r is the interest rate.

,

• n is the number of times per year compounded.

,

• t is the time in years.

When we have that n is equal to 12, we are talking here about that the amount of money is being compounded monthly (we have 12 months in a year, 12 periods, n = 12). <em>Therefore, we are dividing the rate, r, by the number of compoundings per year, n, and this is the rate per each new compounding period of time, r/n, and, in this case, n = 12 (monthly interest rate). </em>

Therefore, in few words, the fraction (0.04/12) is the monthly interest rate (option C).

[If we see the other options, we have:

• The daily interest rate would be given by 0.04/365.

,

• How long the money has been in the account is time, t.

,

• The starting balance in the account is the Principal, P. ]

If the each side of equalaterial triangle is a cm. what is the area?​
Yuri [45]

Step-by-step explanation:

area \: of \: a \: triangle =  \frac{1}{2}  \times base \times height \\  \\ base =  \frac{a}{2} cm \\  {h}^{2}  +   {( \frac{a}{2} )}^{2}  =  {a}^{2}  \\  \\ h =  \sqrt{ {a}^{2} -  \frac{ {a}^{2} }{4}  }  \\  \\ area \: of \: triangle =  \frac{1}{2}  \times b \times h \\  =  \frac{1}{2}  \times  \frac{a}{2}  \times  \sqrt{ {a}^{2}  -  \frac{ {a}^{2} }{4} }  \\  \\  =  \frac{a}{4}  \times  \sqrt{ {a}^{2} -  \frac{ {a}^{2} }{4}  }
