You have deposited SEK 10,000 in an account that gives 2% interest every year. How much have you received in interest after two years?

Answers

Answer:

404

Step-by-step explanation:

2% of 10000 = 200 in the first year, setting your account to 10200

2% of 10200 = 204 in the second year, setting your account to 10404

In the total of 2 years, you received 404 extra

Answer:

Deposite amount (P) = 10000

Interest ( R)    = 2%

Years (T) = 2

Formula

S.I =PRT÷100

S.I =10000×2×2÷100

S.I =40000÷100

S.I =400

You have received interest after 2 years =400

Answer:

Option (D)

Step-by-step explanation:

Linear equations are in the form of y = mx + b

Here, m = slope of the linear function

b = y-intercept

Quadratic function → y = ax² + bx + c

By these properties, y - 6 = x² represents the quadratic equation which is non linear.

Therefore, Option (D) will be the correct option.

6. Geeta borrowed. * 15.000 for 18 months at a
certain rate of interest compounded semi-
annually. If at the end of six months it
amounted to 15.600; calculate :
(i) the rate of interest per annum.
(ii) the total amount of money that Geeta
must pay at the end of 18 months in
order to clear the account.​

Answers

Answer:

i) 8%

ii) 16,872.96

Step-by-step explanation:

A) Since she borrowed 15000 and at the end of six months it amounted to 15600. What it means is that;

Interest; i = 15600 - 15000 = 600

Now,formula for rate of interest is;

R = (100i)/(Pt)

Where;

i = 600

P is amount borrowed = 15000

t is time period compounded. Since it's compounded semi annually, then t = ½

Thus, from PRT/100 = i, we can find R as;

R = (100 × 600)/(15000 × (6/12))%

R = 8%

B) After 12 months, which is another semi annual period after 6 months, the Interest will now be;

15600 × 8% × (6/12) = 624

Thus, amount due at this point is 15600 + 624 = 16224

After 18 months which is another semi annual period after 12 months, the Interest will now be;

16224 × 8% × (6/12) = 648.96

Thus, amount due at this point is 16224 + 648.96 = 16,872.96

What formula do i use when it tells me to find the area with a given circumference? If you know please give an example as well, thank you.

Answers

Answer:

Step-by-step explanation:

A = C^2 / 4 x pi

so if the circumfernce was 10 you would square it to make it 100 and then you would do 4 x pi to get 12.57 ( rounded).

you would then just divide 100 by 12.57 = 7.96 ( rounded)

∠MNQ = 31

Step-by-step explanation:

Set ∠MNQ and ∠NQP equal to each other.

∠MNQ = ∠NQP

5c + 6 = 7c - 4

10 = 2c

c = 5

Then substitute back into ∠MNQ.

∠MNQ = 5c + 6

∠MNQ = 5(5) + 6

∠MNQ = 25 + 6

∠MNQ = 31

Graph quadrilateral abcd whose vertex matrix is shown below. Then graph the dilation of quadrilateral abcd with a scale factor of 3 on the same coordinated grid. Quadrilateral abcd with vertex matrix -1 5 5 -4
2 5 3 -1

Answers

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of an object.

Given the vertex matrix of quadrilateral ABCD as:

[tex]\left[\begin{array}{cccc}-1&5&5&-4\\2&5&3&-1\end{array}\right][/tex]

Therefore the vertex of quadrilateral ABCD is at A(-1, 2), B(5, 5), C(5, 3) and D(-4, -1).

Quadrilateral ABCD is dilated by a scale factor of 3 to produce quadrilateral A'B'C'D'.

Hence, the vertex matrix of quadrilateral A'B'C'D' is:

[tex]3\left[\begin{array}{cccc}-1&5&5&-4\\2&5&3&-1\end{array}\right]=\left[\begin{array}{cccc}-3&15&15&-20\\6&15&9&-3\end{array}\right][/tex]

Therefore the vertex of quadrilateral A'B'C'D' is at A'(-3, 6), B'(15, 15), C'(15, 9) and D'(-20, -3).

The correct option is figure A

if 4x-y/2x+y=5/3, then x/y=?

Answers

Answer:

[tex]\frac{x}{y}[/tex] = 4

Step-by-step explanation:

Expressing in fractional form, that is

[tex]\frac{4x-y}{2x+y}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )

3(4x - y) = 5(2x + y) ← distribute both sides

12x - 3y = 10x + 5y ( subtract 10x from both sides )

2x - 3y = 5y ( add 3y to both sides )

2x = 8y ( divide both sides by 2 )

x = 4y ( divide both sides by y )

[tex]\frac{x}{y}[/tex] = 4

Answer:

[tex] \boxed{ \frac{x}{y} = 4}[/tex]

Step-by-step explanation:

[tex]if \: \frac{4x-y}{2x+y}=\frac{5}{3}, \: then \: \frac{x}{y} = : \\ 3(4x - y) = 5(2x + y) \\ 12x - 3y = 10x + 5y \\ 2x = 8y \\ \frac{2x}{y} = 8 \\ \frac{x}{y} = 4[/tex]

C warmer in Tucson than it was in Minneapolis. If the temperatures in Tucson and Minneapolis are opposites, what is the temperature in Tucson?

PLEASE ANSWER QUICK!!!!!!!!!

Answers

Answer:

[tex]T^\circ = -12^\circ[/tex]

Step-by-step explanation:

Given

Represent the temperature in Tucson with T and that in Minneapolis with M.

From the first statement, we have:

[tex]T^\circ = M^\circ - 24^\circ[/tex]

From the second, we have:

[tex]T^\circ = -M^\circ[/tex] or [tex]M^\circ = -T^\circ[/tex] --- i.e. both are opposite numbers

Required

Find T

To calculate T, substitute -T for M in [tex]T^\circ = M^\circ - 24^\circ[/tex]

This gives:

[tex]T^\circ = -T^\circ - 24^\circ[/tex]

Collect Like Terms

[tex]T^\circ +T^\circ =- 24^\circ[/tex]

[tex]2T^\circ =- 24^\circ[/tex]

Make T the subject

[tex]T^\circ =- 24^\circ/2[/tex]

[tex]T^\circ = -12^\circ[/tex]

Hence, the temperature in Tucson is [tex]-12^\circ[/tex]
