Given:

Principal value = $12000

Rate of interest = 2.5%

To find:

Total amount after 15 years.

Solution:

Formula for amount discontinuously compounded interest is

A=Pe^{rt}

where, P is principal, r is rate of interest and t is time in years.

Substitute P=12000, r=0.025 and t=15 in the above formula.

A=12000e^{0.025(15)}

A=12000e^{0.375}

A=12000(1.45499141462)

A=17459.8969754

A\approx 17459.897

Therefore, the amount after 15 years is $17459.897.

Ahmad drove 360miles in 5hours.<br> At the same rate, how long would it take him to drive 864miles?
AVprozaik [17]

It will take Ahmad 12 hours to drive 864 miles

Step-by-step explanation:

  • Step 1: Find the speed of Ahmad.

Distance = 360 miles

Time = 5 hours

⇒ Speed = Distance/Time = 360/5 = 72 miles/hour

  • Step 2: Find the time required to drive 864 miles

⇒ Time = Distance/Speed = 864/72 = 12 hours

Write the equation with both x= 8 and x= -8 as solution
nlexa [21]

Answer:

y = x^2 - 64

Step-by-step explanation:

Hello!

We can use the factored form of a Quadratic to find an equation with 8 and -8 as our solution.

<h3>Factored Form: y = a(x - h)(x - k)</h3>

The value in each parenthesis should be 0. So 8 and -8 can be flipped and used for h and k.

  • y = a(x - h)(x - k)
  • y = a(x - 8)(x+ 8)

This will give roots 8 and -8 for x.

  • y = 1(x - 8)(x + 8)\\
  • y = x^2 - 64

A possible equation is y = x^2 - 64.

Find the surface area of each figure?Please help
kolbaska11 [484]
--------------------------------------------------
Surface area of the cube
--------------------------------------------------
6(2.5 x 2.5) = 37.5m²

<em>(* Each area is 2.5 x 2.5, and there are 6 sides to the cube)</em>

--------------------------------------------------
Surface area of the rectangle prism
--------------------------------------------------
2(11 x 7) + 2(9 x 7) + 2(9 x 11) = 478m²

<em>(* The opposite side of the rectangle area is the same, therefore x2)
</em>
--------------------------------------------------
Overlapping area
--------------------------------------------------
2.5 x 2.5 = 6.25m²

--------------------------------------------------
Surface area of the composite figure
--------------------------------------------------
37.5 + 478 - 2(6.25) = 503m²

<em>(* The bottom of the cube and the top of the rectangle prism overlapped, so the area is overlapped twice, minus 2 times of that area)</em>

--------------------------------------------------
Answer: 503m²
--------------------------------------------------
