Answer:

x = 2

Step-by-step explanation:

If ABCD is a parallelogram,

that means the length of BC must be equal to the length of AD

BC = AD

25x + 1 = 7x + 37

25x - 7x = 37 -1

18x = 36

x = 36/18

x = 2

What is the solution to the equation?

Oxana [17]

ANSWER

EXPLANATION

The given equation is

$\frac{ - 3d}{ {d}^{2} - 2d - 8} + \frac{3}{d - 4} = \frac{ - 2}{d + 2}$

Factor the first fraction to get,

$\frac{ - 3d}{(d + 2)(d - 4)} + \frac{3}{d - 4} = \frac{ - 2}{d + 2}$

Multiply through by (d+2)(d-4)

$- 3d + 3(d + 2) = - 2(d - 4)$

Expand:

$- 3d + 3d + 6 = - 2d + 8$

$6 = - 2d + 8$

$6 - 8= - 2d$

$- 2 = - 2d$

divide both sides by -2

$d = 1$

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

Pachacha [2.7K]

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 = $10,000
Interest Rate = 8% = 0.08
number 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:

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

$\mathbf{A = 10000(1 + \dfrac{0.08\times 1}{4})^{4 \times \frac{1}{2}}}$

$\mathbf{A = 10000(1.02)^2}}$

A = $10,404

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

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

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

$\mathbf{A = 10000(1 + \dfrac{0.08\times 1}{4})^{4 \times 5}}$

$\mathbf{A = 10000(1.02)^20}}$

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

Figure not drawn to scale.

DerKrebs [107]

Though you do not provide a diagram, I am going to give this a try by assuming that O is the center of the circle, OA is a radius, and angle AOB is a central angle that measures 88 degrees.

We want to find out the area of sector AOB. First, we need to find the area of the entire circle. The area of a circle is given by $A= \pi r^{2}$ and since the radius of this circle is equal to 1, the area is $\pi ( 1^{2} )= \pi$

Next we need to know what fraction of the circle sector AOB represents. The distance around the circle is 360 degrees but the central angle that intercepts arc AB is 88 degrees. That meas that the fraction of the circle the sector represents is given by $\frac{88}{360}= \frac{11}{45}$

We multiply this by the area to obtain $\frac{11}{45} \pi$ which is the area of the sector.
