she was not correct, 2/4 is not equal to 3/16

Step-by-step explanation:

3/4 garden are roses

1/4 of those are red  (1/4 of 3/4)

3/4 (1/4) = 3/16 of her garden are red roses

Answer:

Yes she is correct because if you have the 3/4 u still have 1/4 un planted an then she adds the 1/4 an that would make it 2/4.

Answer:

\(q=45\)

Step-by-step explanation:

Notice that \((q+2)^{\circ}\) and \((3q-2)^{\circ}\) form a linear pair, that is, they sum to \(180^{\circ}\) as follows:

\((q+2)^{\circ}+(3q-2)^{\circ}=180^{\circ}\\(q+2+3q-2)^{\circ}=180^{\circ}\\(4q)^{\circ}=180^{\circ}\\4q=180\\q=\frac{180}{4}\\q=45\)

The images best represents the result is image W.

We have, the image is rotated about the x-axis.

Now, rotating around x axis can give the other half of the image.

Also, rotating about x axis gives the mirror image of the figure.

So, the rotation leads to a circle.

and, In three dimensional we can say that Sphere.

Thus, the required image is W.

To eliminate the y-terms in this system of equations, we can multiply the second equation by 2 and add it to the first equation.

We have,

To eliminate the y-terms in this system of equations, we can multiply the second equation by 2 and add it to the first equation.

This will result in the y-terms canceling out, and we will be left with only x-terms on one side of the equation, which we can then solve for x.

So, multiplying the second equation by 2, we get:

2(3x + 4y) = 2(5)

6x + 8y = 10

Now, adding this to the first equation, we get:

4x - 8y + 6x + 8y = 20 + 10

10x = 30

Dividing both sides by 10, we get:

x = 3

Now, we can substitute this value of x back into either of the original equations to solve for y.

4x - 8y = 2

So,

4(3) - 8y = 20

12 - 8y = 20

-8y = 8

y = -1

Therefore,

The solution to the system of equations is (x, y) = (3, -1).

Step-by-step explanation:

The f(9) means that the value of x would be 9 in any given equations or functions.

For example:

\(f(x) = 2x^{2} + 5\\f(9) = 2(9)^{2} + 5\\f(9) = 2(81) + 5\\f(9) = 162 + 5\\f(9) = 167\)

The length of AB is AB = 8 units.

What is distance between two points?

The length of a straight line in the coordinate plane that connects two points in space is what is referred to as their distance. We use the absolute value to calculate the distance between any two points because it is impossible for this distance to be negative.

Consider, the given points A (-4, -3), B (4, -3), C (4, -7), D (-4, -7).

We have to find the length of AB.

Consider, the distance formula,

\(d = \sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}\)

where,

\((x_1, y_1)\) and \((x_2, y_2)\) are the points.

Here,

\((x_1, x_2) = (-4, -3)\\(x_2, y_2) = (4, -3)\)

Plug these values in the above formula,

\(d = \sqrt{(4-(-4))^2+(-3-(-3))^2} \\d = \sqrt{8^2 +0^2} \\d = \sqrt{8^2} \\d = 8\)

Hence, the length of AB is AB = 8 units.

Step-by-step explanation:

Answer:

B y= -5/4x+3

Step-by-step explanation:

a) The number of integer-valued solutions is 61, (b) the number of solutions is 62, (c) the number of solutions is 63, and (d) the number of solutions is 6.

a) The number of integer-valued solutions to x1 + x2 + x3 + x4 + x5 = 63, where all xi > 0, can be found using the stars and bars method. We want to find the number of ways to place 63 "stars" into 5 "bars", such that each bar has at least one star.

This is equivalent to the number of solutions to (x1 - 1) + (x2 - 1) + (x3 - 1) + (x4 - 1) + (x5 - 1) = 57, where all xi are non-negative integers. The number of solutions is given by the coefficient of x57 in the expansion of (x + 1)5, which is (5 + 57 - 1) choose (57) = 5 + 57 choose 57 = 61.

b) The number of integer-valued solutions to x1 + x2 + x3 + x4 + x5 = 63, where all xi ≥ 0, can be found using the same method as above. This is equivalent to the number of solutions to x1 + x2 + x3 + x4 + x5 = 63, where all xi are non-negative integers.

The number of solutions is given by the coefficient of x63 in the expansion of (x + 1)5, which is (5 + 63 - 1) choose (63) = 5 + 63 choose 63 = 62.

c) The number of integer-valued solutions to x1 + x2 + x3 + x4 + x5 ≤ 63, where all xi ≥ 0, can be found using the generating function method.

The generating function for the sequence of non-negative integers is given by (1 - x)^-1 = 1 + x + x^2 + x^3 + ... The coefficient of x^n in this series gives the number of solutions to x1 + x2 + x3 + ... + xk = n, where all xi are non-negative integers.

The coefficient of x^63 in (1 - x)^-1 is 1, and the coefficient of x^64 is 0, so there is only 1 solution where x1 + x2 + x3 + x4 + x5 = 63.

d) The number of integer-valued solutions to x1 + x2 + x3 + x4 + x5 = 63, where all xi ≥ 0, x2 ≥ 10, can be found by subtracting the number of solutions where x2 < 10 from the total number of solutions where all xi ≥ 0.

Let's call the number of solutions where x2 < 10 as S1 and the total number of solutions where all xi ≥ 0 as S2. Then, S2 - S1 = the number of solutions where x2 ≥ 10. To find S1, we use the stars and bars method as before, but now we need to place 53 stars into 4 bars since x2 must be at least 10.

The number of solutions is (4 + 53 - 1). Choose (53) = 56. To find S2, we use the generating function method as before. The number of solutions is (5 + 63 - 1). Choose (63) = 62. Thus, S2 - S1 = 62 - 56 = 6.

Answer:

The required matrix is\(A = \left[\begin{array}{ccc}1.07&-0.21\\-0.86&1.35\end{array}\right]\)

Step-by-step explanation:

Matrix of rotation:

\(P = \left[\begin{array}{ccc}cos\pi/4&-sin\pi/4\\sin\pi/4&cos\pi/4\end{array}\right]\)

\(P = \left[\begin{array}{ccc}1/\sqrt{2} &-1/\sqrt{2} \\1/\sqrt{2} &1/\sqrt{2}\end{array}\right]\)

x' + iy' = (x + iy)(cosθ + isinθ)

x' = x cosθ - ysinθ

y' = x sinθ + ycosθ

In matrix form:

\(\left[\begin{array}{ccc}x'\\y'\end{array}\right] = \left[\begin{array}{ccc}cos\theta&-sin\theta\\sin \theta&cos\theta\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right]\)

The matrix stretches by 1.8 on the x axis and 0.7 on the y axis

i.e. x' = 1.8x

y' = 0.7y

\(\left[\begin{array}{ccc}x'\\y'\end{array}\right] = \left[\begin{array}{ccc}1.8&0\\0&0.7\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right]\)

\(Q = \left[\begin{array}{ccc}1.8&0\\0&0.7\end{array}\right]\)

According to the question, the result is rotated by pi/3 clockwise radians

\(R = \left[\begin{array}{ccc}cos(-\pi/3)& -sin(-\pi/3)\\-sin(\pi/3)&cos(\pi/3)\end{array}\right]\)

\(R = \left[\begin{array}{ccc}1/2&\sqrt{3}/2 \\-\sqrt{3}/2 &1/2\end{array}\right]\)

To get the matrix A, we would multiply matrices R, Q and P together.

\(A = RQP = \left[\begin{array}{ccc}1/2&\sqrt{3}/2 \\-\sqrt{3}/2 &1/2\end{array}\right] \left[\begin{array}{ccc}1.8&0\\0&0.7\end{array}\right] \left[\begin{array}{ccc}1/\sqrt{2} &-1/\sqrt{2} \\1/\sqrt{2} &1/\sqrt{2}\end{array}\right]\)

\(A = \left[\begin{array}{ccc}1.07&-0.21\\-0.86&1.35\end{array}\right]\)

There are 8 to take Lara and Hayden to volunteer the same number.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Lara already volunteered 50 hours and will volunteer 5 hours more each week.

And, Hayden already volunteered to 10 hours and will volunteer 10 hours each week .

Now, For Lara;

⇒ 50 + 5x

And, For Hayden;

⇒ 10 + 10x

So, For same number of volunteer is,

⇒ 50 + 5x = 10 + 10x

⇒ 50 - 10 = 10x - 5x

⇒ 40 = 5x

⇒ x = 40/5

⇒ x = 8
