An Investment of $10,000 yields 8% interest compounded quarterly.

What will be the accumulated capital after 6 months?
What will be the accumulated capital after 5 years?

Answers

An Investment of $10,000 yields 8% interest compounded quarterly.  The accumulated capital after 6 months is $10,404. The accumulated capital after 5 years is $14.859.47

From the information given;

The principal amount of investment = $10,000Interest Rate = 8% = 0.08number of times it get compounded = 4

a. we are to determine the amount of the accumulated capital after 6 months.

i.e. when time (t) = 6 months.

Now, using the formula for calculating the amount value of the accumulated capital:

[tex]\mathbf{A = P(1 + \dfrac{r}{n})^{nt}}[/tex]

[tex]\mathbf{A = 10000(1 + \dfrac{0.08\times 1}{4})^{4 \times \frac{1}{2}}}[/tex]

[tex]\mathbf{A = 10000(1.02)^2}}[/tex]

A = $10,404

b. we are to determine the amount of the accumulated capital after 5 years

i.e. when time (t) = 5 years

[tex]\mathbf{A = P(1 + \dfrac{r}{n})^{nt}}[/tex]

[tex]\mathbf{A = 10000(1 + \dfrac{0.08\times 1}{4})^{4 \times 5}}[/tex]

[tex]\mathbf{A = 10000(1.02)^20}}[/tex]

A = $14859.47

Therefore, we can conclude that the accumulated capital after 6 months is $10,404 and the accumulated capital after 5 years is $14859.47

Answer:

Option D

Step-by-step explanation:

The first two options don't make sense as absolute value is always positive.

The third option requires the answer to be within one interval but our answer is the combination of two intervals.

Let's verify if the last option is correct:

|2x - 3| - 1 > 4|2x - 3| > 51) 2x - 3 > 5 ⇒ 2x > 8 ⇒ x > 42) 2x - 3 < - 5 ⇒ 2x - 3 < -2 ⇒ x < - 1

14) Andre went hiking by his house, The first trail he hiked took him 4.5 miles away from his
house. The second trail he hiked took him 2.4 miles closer to his house. The third trail
took him 1.7 miles further away from his house. After Andre hiked the three trails, how
far from his house was he?

Answers

Answer : 3.8 miles
Step by step explanation :
The calculation is the following :
4.5 miles of the first hike minus 2.4 miles of the second hike
4.5 - 2.4 = 2.1
Then you have to add those 2.1 miles the 1.7 miles of the third and last hike
2.1 + 1.7 = 3.8 miles

2.5+x =81−8.1 find x

Answers

The answer is x=70.4

Answer:

[tex] \sf \: x = 70.4[/tex]

Step-by-step explanation:

Given equation,

→ 2.5 + x = 81 - 8.1

Now the value of x will be,

→ 2.5 + x = 81 - 8.1

→ 2.5 + x = 72.9

→ x = 72.9 - 2.5

→ [ x = 70.4 ]

Hence, value of x is 70.4.

Answer:

(-3, -9)

Step-by-step explanation:

Find the difference in the x and y values of the original point (-8, -9) and the translated point (-11, -14) and apply them to the given point (0, -6). -11 - (-8) = -3 for the x, and -14 - (-9) = -5 for the y. This means you must subtract 3 and subtract 5 from a point to get the translation. 0 - 3 = -3 for the x value of the point, and -6 - 3 = -9 for the y value. This gives you a translated point of (-3, -9).
