To find the effective interest rate the formula is
R=(1+r/k)^(k)-1
R=?
r=nominal Interest rate 0.1364
K=compounded daily 365
Plug in the formula
R=(1+0.1364÷365)^(365)−1
R=0.1461 This the effective interest rate 14.61%
As you can see that the effective interest rate is greater than the nominal interest rate by
0.1461−0.1364=0.0097×100=0.97%

So the answer is a

Answer:

-12.5%

Step-by-step explanation:

The percentage change in your time can be computed using ...

pct change = ((new value)/(old value) -1) × 100%

= (28/32 -1) × 100%

= (0.875 -1) × 100% = -12.5%

The time to finish level 2 decreased by 12.5%.

Mazyrski [523]

Answer:

In traffic, she drove for 3 hours

and After the traffic cleared she drove for 2 hours.

Explanation:

Given that the road trip was 136 miles;

$d=136$

The first part of the trip there was lots of traffic, she only averaged 16 mph;

$v_1=16$

The second part of the trip there was no traffic so she could drive 44 mph;

$v_2=44$

She traveled for a total of 5 hours;

$t=5$

let x represent the time in traffic when she traveled at 16 mph

$t_1=x$

the time the traffic is clear would be;

$t_2=t-t_1=5-x$

Recall that distance equals speed multiply by time;

$d=v_1t_1_{}_{}^{}+v_2t_2$

substituting the values;

$136=16x+44(5-x)$

solving for x;

$\begin{gathered} 136=16x+220-44x \\ 44x-16x=220-136 \\ 28x=84 \\ x=\frac{84}{28} \\ x=3 \end{gathered}$

So;

$\begin{gathered} t_1=3\text{ hours} \\ t_2=5-x=5-3=2 \\ t_2=2\text{ hours} \end{gathered}$

Therefore, In traffic, she drove for 3 hours

and After the traffic cleared she drove for 2 hours.
