Madeline invests $25,000 in an account that offers a compound interest rate
of 9.5% per year. Which of the following is the correct equation for how much
Madeline will have after 8 years?

Answers

b

25,000 x (0.95)*8 means the interest changes every year and the interest is calculated of the annual rate

The correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex]  which is in option [tex](b)[/tex].

What is compound interest ?

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest

Amount [tex]=P(1+\frac{R}{100})^t[/tex]

We have,

Principal [tex]=\$25,000[/tex]

Rate[tex]=9.5\%[/tex]

Time [tex]=8[/tex] years

Now,

Using the above mentioned formula,

Amount [tex]=P(1+\frac{R}{100})^t[/tex]

              [tex]=25000(1+\frac{9.5}{100})^8[/tex]

Amount [tex]=25000(1+0.095)^8[/tex]

So, the equation for final amount  is [tex]25000(1+0.095)^8[/tex].

Hence, we can say that the correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex] .

find a20

Answers

Answer:

a20 = -108

Step-by-step explanation:

53 - 62 = -9

44 - 53  = -9

35 - 44  = -9

Then the intervall is -9

The first number is 63

63 + (19*-9) = 63 - 171 = -108

A map uses a scale of 3/4 in = 80 miles. If two buildings are 60 miles apart in real life, how far apart would they be drawn on the map?

Answers

Given:

The scale of a map is [tex]\dfrac{3}{4}\ in=80\ miles[/tex].

The distance between two buildings is 60 miles.

To find:

The distance between the given building on the map.

Solution:

We have,

[tex]\dfrac{3}{4}\ in=80\ miles[/tex]

It means, 80 miles in real life = [tex]\dfrac{3}{4}\ in[/tex] on the map.

1 mile in real life = [tex]\dfrac{3}{4\times 80}\ in[/tex] on the map.

60 mile in real life = [tex]\dfrac{3\times 60}{4\times 80}\ in[/tex] on the map.

                              = [tex]\dfrac{180}{320}\ in[/tex] on the map.

                              = [tex]\dfrac{9}{16}\ in[/tex] on the map.

Therefore, the buildings are [tex]\dfrac{9}{16}\ in[/tex] apart on the map.

Point B has coordinates ​(​1,2​). The​ x-coordinate of point A is -8. The distance between point A and point B is 15 units. What are the possible coordinates of point​ A?

Answers

Answer:

The possible coordinates of point A are [tex]A_{1} (x,y) = (-8, 14)[/tex] and [tex]A_{2} (x,y) = (-8, -10)[/tex], respectively.

Step-by-step explanation:

From Analytical Geometry, we have the Equation of the Distance of a Line Segment between two points:

[tex]l_{AB} = \sqrt{(x_{B}-x_{A})^{2} + (y_{B}-y_{A})^{2}}[/tex] (1)

Where:

[tex]l_{AB}[/tex] - Length of the line segment AB.

[tex]x_{A}, x_{B}[/tex] - x-coordinates of points A and B.

[tex]y_{A}, y_{B}[/tex] - y-coordinates of points A and B.

If we know that [tex]l_{AB} = 15[/tex], [tex]x_{A} = -8[/tex], [tex]x_{B} = 1[/tex] and [tex]y_{B} = 2[/tex], then the possible coordinates of point A is:

[tex]\sqrt{(1+8)^{2}+(2-y_{A})^{2}} = 15[/tex]

[tex]81 + (2-y_{A})^{2} = 225[/tex]

[tex](2-y_{A})^{2} = 144[/tex]

[tex]2-y_{A} = \pm 12[/tex]

There are two possible solutions:

1) [tex]2-y_{A} = -12[/tex]

[tex]y_{A} = 14[/tex]

2) [tex]2 - y_{A} = 12[/tex]

[tex]y_{A} = -10[/tex]

The possible coordinates of point A are [tex]A_{1} (x,y) = (-8, 14)[/tex] and [tex]A_{2} (x,y) = (-8, -10)[/tex], respectively.

*Please show work. (Is not mandatory but try to*

Answers

Answer:

1

Step-by-step explanation:

(133)/7 - 18

133 ÷ 7 = 19

19 - 18 = 1

Answer: y = 1

Step-by-step explanation:

Well if x is 133 then the problem is y = (133/7) -18

and 133/7 is 19

so the problem is y = 19 - 18

and 19 - 18 is 1, so

y = 1

A trader bought 40 shirts for Birr 220 and sold them at Birr 72 each
Find the profit percentage.

Answers

Given:

Cost price of 40 shirts = Birr 220

Selling price of each shirt = Birr 72

To find:

The profit percentage.

Solution:

We have,

Cost price (CP) of 40 shirts = Birr 220

Selling price (SP) of each shirt = Birr 72

So, the selling price (SP) of 40 shirts is:

[tex]72\times 40=2880[/tex]

We need to find the profit percentage.

[tex]\text{Profit percentage}=\dfrac{SP-CP}{CP}\times 100[/tex]

[tex]\text{Profit percentage}=\dfrac{2880-220}{220}\times 100[/tex]

[tex]\text{Profit percentage}=\dfrac{2660}{220}\times 100[/tex]

[tex]\text{Profit percentage}=1209.09\%[/tex]

Therefore, the profit percentage is 1209.09%.

If the length of the 45° region of this circle is 10 inches, what is the radius of the circle? Use and round to the nearest tenth.

Answers

Answer:

12.71in

step explanation:

The Length of an arc given is expressed as;

A = theta/360 * 2πr

10 = 45/360 * 2 * 3.14r

10 = 1/8 * 6.28r

Cross multiply

10 * 8 = 6.28r

80 = 6.28r

r = 80/6.28

r = 12.74in

Hence the radius is 12.71in

The lights from the windows of the large buildings fell upon some of the icicled trees that stood beneath them. We were led toward an open door, where the brightness of the lights within flooded out over the heads of the excited palefaces who blocked our way. My body trembled more from fear than from the snow I trod upon.Entering the house, I stood close against the wall. The strong glaring light in the large whitewashed room dazzled my eyes. The noisy hurrying of hard shoes upon a bare wooden floor increased the whirring in my ears. My only safety seemed to be in keeping next to the wall. As I was wondering in which direction to escape from all this confusion, two warm hands grasped me firmly, and in the same moment I was tossed high in midair. A rosy-cheeked paleface woman caught me in her arms. I was both frightened and insulted by such trifling. I stared into her eyes, wishing her to let me stand on my own feet, but she jumped me up and down with increasing enthusiasm. My mother had never made a plaything of her wee daughter.
