Given the formula A = P(1 + )". compute A (rounded to two decimal places) if P = 10,000,7

Flura [38]

Answer:

A = 16010.32

Step-by-step explanation:

Given that,

$A=P(1+\dfrac{r}{k})^n$

Put P = 10,000, r = 0.08, k = 2 and n = 12 in the above formula to find A.

$A=10,000(1+\dfrac{0.08}{2})^{12}\\\\=10,000\times (1.04)^{12}\\\\=16,010.32$

So, the value of A is 16010.32. Hence, the correct option is (B).

A bus traveled on a level road for 4 hours at an average speed of 20 miles per hour faster than it traveled on a winding road. T

Kruka [31]

To solve this problem, we must recall that the formula for velocity assuming linear motion:

v = d / t

Where,

v = velocity

d = distance

t = time

For condition 1: bus travelling on a level road

v1 = d1 / t1

(v2 + 20) = (449 – d2) / 4 --->1

For condition 2: bus travelling on a winding road

v2 = d2 / t2

v2 = d2 / 5 --->2

Combining equations 1 and 2:

(d2 / 5) + 20 = (449 – d2) / 4

0.8 d2 + 80 = 449 – d2

1.8 d2 = 369

d2 = 205 miles

Using equation 2, find for v2:

v2 = 205 / 5

v2 = 41 mph

Since v1 = v2 + 20

v1 = 41 + 20

v1 = 61 mph

Therefore the average speed on the level road is 61 mph.

19. Find the value of: 4/3tan^2 30° + Sin^2 60° – 3Cos^2 30°+ 3tan^2. 60° - 2tan^2 45°

Julli [10]

9514 1404 393

Answer:

107/18

Step-by-step explanation:

Your calculator and/or knowledge of trig function values can help you evaluate this.

= 4/3(1/3) +3/4 -3(3/4) +3(3) -2(1)

= 4/9 +3/4 -9/4 +9 -2

= 107/18

___

tan(30°) = 1/√3

tan(45°) = 1

tan(60°) = √3

sin(60°) = cos(30°) = √3/2

the length of a rectangular yard is 4 feet more than the width. the perimeter of the yard is 208 feet. write the equation that r

ad-work [718]

Answer:

Length = 54 ft.

Width = 50 ft.

Step-by-step explanation:

Let the width of the rectangle be 'w'.

According to question ,

Length = w + 4

Perimeter = 208 ft.

We know that $perimeter = 2(l + w)$ where l = length & w = width

So,

$2(w + 4 + w) = 208$

$= > 2(2w + 4) = 208$

$= > 2w + 4 = \frac{208}{2} = 104$

$= > 2w = 104 - 4 = 100$

$= > w = \frac{100}{2} = 50$

Width = 50 ft.

=> Length = 50 + 4 = 54 ft.

Subtraction property of equality

Natali5045456 [20]

It tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.
