Which transformation is not an isometry
Answer:
Third option(double circle)
Step-by-step explanation:
Isometry (iso meaning same and metry meaning measure)
preserves the length and overall mass/size of a shape during a transformation. The 3rd option is the only shape that changes size in the examples, making it a non isometric transformation.
What is the value of g(f(x)) when x = -2 if f(x) = x³
and g(x) =
2x+1
when x < 0
x²-1
when x>0
Answer:
g(f(-2)) = -15
Step-by-step explanation:
• f(x) = x³
Then
f(-2) = (-2)³ = -8
• When x = -2 → g(f(x)) = g(f(-2)) = g(-8)
Since -8 ≤ 0 then g(-8) = 2×(-8) + 1 = -16 + 1 = -15
Conclusion:
g(f(-2)) = -15
(2a+b) (a-b) + (2a-b) (a+b)
Answer: 4a^2-2b^2 (I think this is right)
Step-by-step explanation:
Using the order of operations I started by multiplying both of the sides separately. The left side of the equation becomes 2a^2-b^2-ab while the right becomes 2a^2-b^2+ab. Then I put the sides together to add them and after combining like terms it becomes 4a^2-2b^2.
Casper has some whipping cream that is 18\%18%18, percent butterfat and some milk that is 4\%4%4, percent butterfat. He wants to make a 500\,\text{mL}500mL500, start text, m, L, end text mixture of them that is 12\%12%12, percent butterfat.
Answer:
CORRECT (SELECTED)
The mixture has less than the intended volume and has more than the intended percent of butterfat.
Explanation: Point LLL is above line aaa, so it represents a scenario where the mixture has more than 12\%12%12, percent butterfat. Also, point LLL is below line bbb, so it represents a scenario where the mixture has a volume of less than 500 \,\text{mL}500mL500, start text, m, L, end text.
Option B. The correct answer to this question is that The mixture has less than the intended volume and has more than the intended percent of butterfat.
How to interpret the graphFrom the graph that we have here, the point L is under the blue line of the graph.
x + y = 500
From here we have
0.18x + 0.04y = 500(0.12)
Continuing on trhe graph the solution is given as x = 285.7 and y = 214.3
From the explanation here we can conclude that option B is correct.

The volume of the octagonal pyramid is 1302 cubic m if the length of the apothem is 7 m.
What is a pyramid that has an octagonal base?The pyramid has an octagonal base with 8 isosceles triangular faces, known as an octagonal base pyramid.
The length of the apothem = 7 m
Side length = 9 m
The area of the one triangle = (1/2)×7×9 = 63/2 square m
The area of the octagonal base = 8(63/2) = 252 square m
The volume of the pyramid = (1/3)(base area)(height)
The volume of the pyramid = (1/3)(252)(15.5)

The equation of a parabola that has intercepts of x=-2 and x=6 and passes through point (8,6) is f(x) = 3/10(x+2)(x-6)
Equation of a parabolaThe standard equation of a parabola is in the form f(x) = (x-a)(x-b)
where a and b are the intercepts of the graph. Given the parabola that has intercepts of x=-2 and x=6, the resulting equation will be:
f(x) = a(x-(-2))(x-6)
f(x) = a(x+2)(x-6)
If the parabola passes through (8, 6), then;
6 = a(8+2)(8-6)
6 = a(20)
a = 6/20
a = 3/10
Substitute
f(x) = 3/10(x+2)(x-6)

2) A(ΔPQT)=0.5*PT*QT, then
3) A=4*0.5*PT*QT; ⇔
A=2*PT*QT; ⇒
4) finally,
A=2*11*9=198 [m²].
The area of the rhombus PQRS is 198 m².
What is Rhombus?A rhombus is a quadrilateral with four vertices, four sides and four angles with all four sides are equal. It has basically a diamond shape. Rhombus will become square if all the angles of the rhombus equals 90°.
Given that, PT = 11 m and QT = 9 m.
We know that diagonals of a rhombus are perpendicular bisectors.
Therefore, RT = 11 m and ST = 9 m.
Area of a rhombus can be found using diagonals as,
Area = [tex]\frac{1}{2}[/tex] × D₁ × D₂
where D₁ and D₂ are the length of two diagonals of the rhombus.
D₁ = PT + RT = 11 + 11 = 22 m
D₂ = QT + ST = 9 + 9 = 18 m
Area = [tex]\frac{1}{2}[/tex] × 22 × 18

Alternate interior anglesAlternate interior angles are found on either side of a transversal where it crosses a pair of parallel lines. They are between the parallel lines. Their vertices are at the junction of the transversal and the parallel lines. Alternate interior angles are congruent.
In this diagram, there are two pairs of alternate interior angles where the two transversals AD and BD cross parallel lines AB and CD.
At points A and D, the alternate interior angles are 70° and x, respectively. This tells you ...
x = 70° . . . . alternate interior angles theorem
At points B and D, the alternate interior angles are w and 70°, respectively. This tells you ...

Angle sumThe angle sum theorem tells you the sum of angles in a triangle is 180°. This fact can be used to find the measure of angle y.
70° +w +y = 180°

OB. f(x) = 13x1
O C. f(x) = x-− 1|
OD. f(x)=x+2
Answer: A
Step-by-step explanation:
This is a fact.
The absolute value parent or modulus function is f ( x ) = | x |
What is Modulus Function?Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = | x |
The absolute value parent function is f(x) = |x|, which represents the absolute value of x.
Option B, f(x) = 13x1, does not represent the absolute value function, as it has a coefficient of 13, which scales the function vertically.
Option C, f(x) = x-− 1|, represents a translation of the absolute value function. The "-1" shifts the function one unit to the right, and the vertical bar denotes the absolute value of the expression within the bar. While it is related to the absolute value function, it is not the parent function itself.
Option D, f(x) = x+2, represents a linear function with a slope of 1, which is not the absolute value function.
Hence , the absolute value parent function is f ( x ) = | x |

Simple interest on a bank loan can be calculated by multiplying the principal times the interest rate times the time. In the formula I = p r t, what does I stand for? a. time c. principal b. interest rate d. simple interest Please select the best answer from the choices provided
Answer:
simple interest
Step-by-step explanation:
this is because r is interest rate, p is principal, and t is time
Answer:
simple interest
Step-by-step explanation:
Simple interest rate is defined as: I = p * r * t. So you're taking the principle amount (initial amount loaned) and multiply it by the interest rate. This gives you the interest rate in a year (usually, depends on time unit of t). Generally speaking, it gives you the interest over a specific amount of time. Now multiply it by the amount of time that's passed. So you're just calculating the total amount of interest. So the I stands for the simple interest.

Find the perimeter of the triangle whose vertices are (−7,−1), (5,−1), and (5,4). Write the exact answer. Do not round.
The perimeter of the triangle is 30 units
How to determine the perimeter?The vertices are (−7,−1), (5,−1), and (5,4).
Start by calculating the distance between the vertices using:
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]
So, we have:
[tex]d1 = \sqrt{(-1 + 1)^2 + (5 + 7)^2[/tex]
d1 = 12
[tex]d2 = \sqrt{(-1 - 4)^2 + (5 - 5)^2[/tex]
d2 =5
[tex]d3 = \sqrt{(-1 - 4)^2 + (-7 - 5)^2[/tex]
d3 = 13
The perimeter is then calculated as:
P = d1 + d2 + d3
This gives
P = 12 + 5 + 13
Evaluate
P = 30
Hence, the perimeter of the triangle is 30 units

Walmart offers a shirt for $45. One week later, they offer the shirt at 15% off. The shirt still doesn't sell, so after another week, Walmart reduces its new price by 20%. How much does the shirt cost now? Walmart offers a shirt for $ 45 . One week later , they offer the shirt at 15 % off . The shirt still doesn't sell , so after another week , Walmart reduces its new price by 20 % . How much does the shirt cost now ?
Answer:
$30.60
Step-by-step explanation:
So when a problem says some price is x% off, it means the current price is now (100-x)% of the original value. So if the shirt is 15% off, the current price is 85% the original value. To find 85% of a number you simple convert the percentage into a decimal, by dividing it by 100 and multiply that decimal by the value. So in this case 85/100 = 0.85. And then 0.85 * 45 = 38.25. Now that it reduces its price by 20%, it's 80% the original value. 38.25 * 0.8 = 30.60.
