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
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

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?
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

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!!!!!!!!!
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]

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.
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

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)

Answer:
∠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

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