Holly wants to save money for an emergency. Holly invests 1,500 in an account that pays an interest rate of 6.75%. How many year
lina2011 [118]
The formula is
A=p (1+r)^t
A future value 7300
P present value 1500
R interest rate 0.0675
T time?
7300=1500 (1+0.0675)^t
Solve for t
Divide both sides by 1500
7300/1500=1.0675^t
Take the log for both sides
Log (7300/1500)=t×log (1.0675)
Divide both sides by log (1.0675)
T=log(7,300÷1,500)÷log(1.0675)
T=24.2 years round your answer to get 24 years

Hope it helps!

The length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81 degrees. What is the ap
GuDViN [60]

Answer:

A.  5.19 units

Step-by-step explanation:

\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle)}

Given:

  • \theta = 81°
  • Arc length = 7.34 units

Substituting given values into the equation and solving for r:

\implies 7.34=2 \pi r\left(\dfrac{81^{\circ}}{360^{\circ}}\right)

\implies 7.34=r\left(\dfrac{18 \pi}{40}\right)

\implies 7.34 \cdot 40=18 \pi r

\implies 293.6=18 \pi r

\implies r=\dfrac{293.6}{18 \pi}

\implies r=5.19 \sf \: units \:(2\:dp)
