PQRS is a parallelogram with QR = 6 cm, QT = 3 cm and ∠PSR = 115°.
a). By the property of a parallelogram,
"Diagonals of a parallelogram bisect each other"
QT = TS
QS = 2(QT)
= 2(3)
= 6 cm
b). "Adjacent angles of a parallelogram are supplementary"
m∠PSR + m∠SRQ = 180°
115° + m∠SRQ = 180°
m∠SRQ = 65°
c). Since, SQ = SR = 6 cm
m∠QSR = m∠SRQ [Opposite angles of the equal sides of an isosceles triangle]
m∠QSR = 65°
By applying triangle sum theorem in ΔQSR,
m∠SQR + m∠QRS + m∠QSR = 180°
m∠SQR + 65° + 65° = 180°
m∠SQR = 50°

Answer: Line 3
Step-by-step explanation:
The stream of water from a fountain follows a parabolic path. The stream reaches a maximum height of 5 feet, represented by a vertex of (3,5), and lands 6 feet from the water jet, represented by (6,0). Write a function in vertex form that models the path of the stream.
The function in vertex form that models the path of the stream is:
\(y = (-5/9)(x - 3)^2 + 5\)
What are vertex?A location where two or more straight lines or curves intersect is referred to as a vertex . A vertex in geometry is sometimes referred to as a corner or an intersection point. The phrase is frequently used to refer to the highest or lowest point on a curve or surface, the place where two lines intersect to make an angle, and the point where two sides of a polygon meet.
The vertex form of the equation of a parabola is given by:
\(y = a(x - h)^2 + k\)
where (h, k) represents the vertex of the parabola.
Using the given vertex and the point (6,0), we can find the value of "a" and plug it into the vertex form to get the equation of the parabolic path of the water stream.
Step 1: Find the value of "a"
Since the vertex is (3,5), we know that:
h = 3
k = 5
Using the point (6,0), we can find the value of "a" as follows:
\(0 = a(6 - 3)^2 + 5\)
\(0 = 9a + 5\)
\(9a = -5\)
\(a = -5/9\)
Step 2: Plug in the values of h, k, and a into the vertex form:
\(y = (-5/9)(x - 3)^2 + 5\)
Therefore, the function in vertex form that models the path of the stream is:
\(y = (-5/9)(x - 3)^2 + 5\)

For what value of k, the following system of equations kx+2y=3, 3x+6y=10 has a unique solution ?
The given system of equations to have a Unique solution, the value of k must be any real number except 1 (k ≠ 1).
The value of k for which the given system of equations has a unique solution, we can use the concept of determinants. The system of equations is as follows:
kx + 2y = 3 -- (1)
3x + 6y = 10 -- (2)
To have a unique solution, the determinant of the coefficients of x and y must not be zero.
The determinant of the coefficient matrix for the system is:
D = | k 2 |
| 3 6 |
By calculating the determinant, we have:
D = (k * 6) - (2 * 3)
D = 6k - 6
For the system to have a unique solution, the determinant D must not equal zero.
6k - 6 ≠ 0
Simplifying the inequality:
6k ≠ 6
Dividing both sides by 6:
k ≠ 1
Therefore, for the given system of equations to have a unique solution, the value of k must be any real number except 1 (k ≠ 1).
In other words, if k is not equal to 1, the system of equations will have a unique solution. If k is equal to 1, the system will either have infinitely many solutions or no solution.

The height of the cylinder is 4 feet.
How to find the height of a cylinder?The volume of a cylinder can be found as follows;
volume of a cylinder = base area × height
Therefore,
base area = πr²
volume of the cylinder = 48π ft³
base area = 12π ft²
Therefore, let's find the height of the cylinder as follows:
48π = 12π × h
divide both sides of the equation by 12π
h = 48π / 12π
h = 4 ft
Therefore,

I don’t know how to solve this
The solution of the given system of equations include the following:
C. a = -3 and b = 6.
How to solve the given system of equations?In order to solve the given system of equations, we would apply the substitution method. For instance, we have the following system of equations:
2a + 3b = 12 .......equation 1.
a = 1/2(b) - 6 .......equation 2.
By using the substitution method to substitute equation 2 into equation 1, we have the following:
2(b/2 - 6) + 3b = 12
b - 12 + 3b = 12
4b = 12 + 12
4b = 24
b = 24/4 = 6.
For the value of a, we have:
a = 1/2(b) - 6
a = 1/2(6) - 6
a = 3 - 6
a = -3.

In order to start a small business, a student takes out a simple interest loan for \( \$ 5000.00 \) for 9 months at a rate of \( 8.25 \% \). a. How much interest must the student pay?
a. the principal (loan amount) is $5000, the rate is 8.25%, and the time is 9 months (expressed in years as 9/12). b. the student will have to pay $306.25 in interest, and the future value of the loan will be $5306.25.
a. The student must pay $306.25 in interest.
To calculate the amount of interest, we can use the formula for simple interest:
Interest = Principal × Rate × Time
In this case, the principal (loan amount) is $5000, the rate is 8.25%, and the time is 9 months (expressed in years as 9/12).
Plugging in these values into the formula, we can calculate the interest amount the student must pay.
b. The future value of the loan is $5306.25.
To find the future value, we add the interest amount to the principal amount.
The future value is calculated using the formula:
Future Value = Principal + Interest
By substituting the values of the principal ($5000) and the interest ($306.25), we can find the future value of the loan.
Therefore, the student will have to pay $306.25 in interest, and the future value of the loan will be $5306.25.

Answer:
a) 191 yards
b) 40 yards
c) 1.5 minutes
Step-by-step explanation:
Given:
ΔPQR is a right triangle with the right angle at Q
PQ = 40 yards; QR = 70 yards
M is the midpoint of PR
jogging rate is 150 yd/min
Find:
a) the perimeter of ΔPQR to the nearest yard
b) QM to the nearest yard
c) the time to jog the path PQMRQP to the nearest tenth minute
Solution:
a) The length of PR can be found from the Pythagorean theorem:
PR² = PQ² +QR²
PR² = 40² +70² = 6500
PR = √6500 ≈ 80.62 . . . . yards
Then the perimeter is ...
perimeter = PQ +QR +PR = 40 +70 +80.62 ≈ 191 yards
__
b) Segment QM divides triangle PQR into two isosceles triangles: PMQ and RMQ. The lengths MP, MQ, and MR are all equal to half the length of PR.
QM = PR/2 = (80.62 yd)/2 = 40.31 yd
QM ≈ 40 yd
__
c) The segments of path PQMRQP can be grouped to simplify the computation of the path length
PQMRQP = PQ +QM +MR +RQ +QP = PQ +(PQ +QR +(QM +MR))
Since QM +MR = PR, the length in the outer parentheses is the perimeter of the triangle. Then the jogger's total path length is ...
PQ + perimeter(ΔPQR) = 40 yd +191 yd = 231 yd
The time it takes to jog that path is ...
time = distance/speed
time = 231 yd/(150 yd/min) = 1.54 min ≈ 1.5 min
It takes about 1.5 minutes.

Type an equation of a parabola that is moved down 2 units, stretched vertically by a factor of 3, and moved left 5 units.
9514 1404 393
Answer:
y = 3x^2 +30x +69
Step-by-step explanation:
Transformations work this way:
g(x) = k·f(x) . . . . vertical stretch by a factor of k
g(x) = f(x -h) +k . . . . translation (right, up) by (h, k)
__
So, the translation down 2 units will make the function be ...
f(x) = x^2 ⇒ f1(x) = f(x) -2 = x^2 -2
The vertical stretch by a factor of 3 will make the function be ...
f1(x) = x^2 -2 ⇒ 3·f1(x) = f2(x) = 3(x^2 -2)
The horizontal translation left 5 units will make the function be ...
f2(x) = 3(x^2 -2) ⇒ f2(x +5) = f3(x) = 3((x +5)^2 -2)
The transformed function equation can be written ...
y = 3((x +5)^2 -2) = 3(x^2 +10x +25 -2)
y = 3x^2 +30x +69
__
The attachment shows the original function and the various transformations. Note that the final function is translated down 6 units from the original. That is because the down translation came before the vertical scaling.

assume that t is a linear transformation. find the standard matrix of t. t: ℝ2→ℝ2 first reflects points through the line x2=−x1 and then reflects points through the origin.
the standard matrix of the linear transformation T: ℝ² → ℝ², which first reflects points through the line x₂ = -x₁ and then reflects points through the origin, is:
[ -1 0 ]
[ 0 1 ]
To find the standard matrix of the linear transformation T: ℝ² → ℝ², we can determine how the basis vectors of ℝ² transform under the given transformation.
The standard basis vectors of ℝ² are:
e₁ = (1, 0) (corresponding to the x-axis)
e₂ = (0, 1) (corresponding to the y-axis)
First, let's apply the reflection through the line x₂ = -x₁:
For e₁ = (1, 0), the reflection through the line x₂ = -x₁ maps it to (-1, 0).
For e₂ = (0, 1), the reflection through the line x₂ = -x₁ maps it to (0, 1).
Next, let's apply the reflection through the origin:
For (-1, 0), the reflection through the origin keeps it the same (-1, 0).
For (0, 1), the reflection through the origin keeps it the same (0, 1).
Now, we have the transformed basis vectors:
T(e₁) = (-1, 0)
T(e₂) = (0, 1)
The standard matrix of the linear transformation T is constructed by placing the transformed basis vectors as columns:
[ -1 0 ]
[ 0 1 ]
