The y-value of the terminal point of the vector is 3.
How to determine the resulting vector by applying rotation about the origin
In this question we must apply a matricial form of rotation, which is a kind of rigid transformation. This transformation is defined by the following formula:
[tex]\vec A' = \vec T\cdot \vec A[/tex], where [tex]\vec A' , \vec A \in \mathbb{R}_{1 \times 2}[/tex], [tex]\vec T \in \mathbb{R}_{2 \times 2}[/tex]
If we knw that [tex]\vec A = \left[\begin{array}{c}- 4\\3\end{array}\right][/tex] and [tex]\vec T = \left[\begin{array}{cc}-1&0\\0&1\end{array}\right][/tex], then the transformed vector column is:
[tex]\left[\begin{array}{cc}x\\y\end{array}\right] = \left[\begin{array}{cc}-1&0\\0&1\end{array}\right] \cdot \left[\begin{array}{cc}-4\\3\end{array}\right][/tex]
[tex]\left[\begin{array}{cc}x\\y\end{array}\right] = \left[\begin{array}{cc}4\\3\end{array}\right][/tex]
The y-value of the terminal point of the vector is 3.

The graph of a liner function is shown on the coordinate grid. what is the slope of the graph of this function?
A-7/3
B-3/7
C- -7/3
D- -3/7
Answers
Answer: C -7/3
Step-by-step explanation: Slope is rise over run, rise/run, and your line means your slope will be negative. So, you will first count straigt down from your firt point until you reach the line of the second point, which is 7. Next, you would count/run to the point, which is 3. Rise/run = -7/3.

What is the value of x in the matrix equation below?
Answers
=======================================================
Explanation:
The -2 outside the first matrix multiplies to every item inside that first matrix.
So the x updates to -2x in the upper left corner.
That -2x adds to the 3 in the upper left corner of the second matrix. The sum -2x+3 must be equal to the value in the upper left corner of the third matrix.
Everything is focused on the upper left corner.
So we must solve -2x+3 = x
Doing so leads to...
-2x+3 = x
3 = x+2x
3 = 3x
3x = 3
x = 3/3
x = 1

Rahul sold a painting at 10% profit. If he had sold it for 240 more, he would have made 15% profit. What is the C.P. of the painting?
please tell ans step by step..
Answers
Answer:
$4800
Step-by-step explanation:
Let x be the C.P of the painting.
Profit=10% of x
Profit=[tex]\frac{10}{100}\times x=\frac{10x}{100}[/tex]
If S.P increase by 240 then
Profit=15% of x=[tex]\frac{15x}{100}[/tex]
For first case
S.P=C.P+ Profit
S.P=x+10x/100
S.P=[tex]\frac{100x+10x}{100}=\frac{110}{100}x[/tex]
For second case
New S.P[tex]=x+\frac{15}{100}x[/tex]
=[tex]\frac{115}{100}x[/tex]
According to question
[tex]240+S.P=\frac{115}{100}x[/tex]
[tex]240+\frac{110x}{100}=\frac{115}{100}x[/tex]
[tex]240=\frac{115}{100}x-\frac{110x}{100}[/tex]
[tex]240=\frac{115x-110x}{100}[/tex]
[tex]240=\frac{5}{100}x[/tex]
[tex]x=\frac{240\times 100}{5}[/tex]
[tex]x=4800[/tex]
Hence, the C.P of the painting=$4800
Samaia buys two water bottles and three bags of chips for $9.45. Abdullah goes to the same store and buys four water bottles, as Samaia, and five bags of chips, same as ones Samaia bought, for $14.75. Which choice below accurately represents a system of equations, w for water bottles and c for chips, for this scenario? Each water bottle is same price and each bag of chips is same price. * A) 3w + 2c = 9.45 AND 5w + 4c = 14.75 B) 2w + 3c = 9.45 AND 4w + 5c = 14.75 3) 2w + 3c = 14.75 AND 4w + 5c = 9.45 D) 5c + 9w = $24.20
Answers
Answer:
B) 2w + 3c = 9.45 AND 4w + 5c = 14.75
Step-by-step explanation:
Let us represent:
Number of water bottles = w
Number of bag of chips = c
Hence:
Samaia buys two water bottles and three bags of chips for $9.45.
2w + 3c = 9.45......Equation 1
Abdullah goes to the same store and buys four water bottles, as Samaia, and five bags of chips, same as ones Samaia bought, for $14.75.
4w + 5c = 14.75......Equation 2
Which choice below accurately represents a system of equations, w for water bottles and c for chips, for this scenario?
Option B) 2w + 3c = 9.45 AND 4w + 5c = 14.75 is the correct option.

The bill at the restaurant was $18.79 estimate the amount to leave as a $10 tip. A. $2.00 B. $3.00 C. $9.00 D. $21.00
Answers
Answer: The correct option is A: $2.00
Step-by-step explanation:
The question should be:
"The bill at the restaurant was $18.79 estimate the amount to leave as a 10% tip. A. $2.00 B. $3.00 C. $9.00 D. $21.00"
The general case is:
When we have a quantity A (where A is the 100%) the X% of A is:
(X%/100%)*A
In this problem, we have a bill of $18,79 and we want to leave a 10% tip.
Then $18,79 is the 100% we want to see how much is the 10% of $18,79
If we use the above equation we get:
Tip = (10%/100%)*$18,79 = $1,879
The option that approaches the best to this amount is option A, $2.00
Then the tip should be $2
The correct option is A.

The hypotenuse of a right triangle measures 15 cm and one of its legs
measures 5 cm. Find the measure of the other leg. If necessary, round to the
nearest tenth.
Answers
Answer:
[see below]
Step-by-step explanation:
Use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
'c' will be the hypotenuse.
The hypotenuse is 15 cm. One of the legs is 5 cm.
[tex]5^2+b^2=15^2\\\\25 + b^2 = 225\\\\25-25+b^2=225-25\\\\b^2=200\\\\\sqrt{b^2}=\sqrt{200}\\\\ b=14.1421356237..., -14.1421356237[/tex]
14.1421356237 ≈ 14.1
The other leg should be about 14.1 cm.
Hope this helps.
The length of the other leg is 14.14 cm rounded to two decimal places.
What is Pythagoras's theorem?In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.
Given, The hypotenuse of a right triangle measures 15 cm, and one of its legs measures 5 cm.
We know,
Hypotenuse² = Base² + Adjacent².
Therefore,
15² = 5² + Adjacent².
Adjacent = √(225 - 25).
Adjacent = √200.
Adjacent = 14.14.
