What is the surface area of the cuboid 3cm 5cm and 2cm.
Answer:
SA = 62 cm2
Step-by-step explanation:
The surface area of the given cuboid will be 62 cm² whose dimensions are cm, 5 cm, and 2 cm.
What is the formula for the total surface area of a cuboid?The total surface of the cuboid = 2(LB+BH+HL)
Consider that the length, width, and height of the cuboid are L, B, and H.
The cuboid is given in the question
Which has the length, width, and height of the cuboid are 3 cm, 5 cm, and 2 cm.
The surface area of the cuboid = 2(LB+BH+HL)
Here L = 3 cm, B = 5 cm, and H = 2 cm
Substitute the values in the above formula, and we get
The surface area of the cuboid = 2(3 × 5 + 5 × 2 + 2 × 3)
The surface area of the cuboid = 2(15 + 10 + 6)
The surface area of the cuboid = 2(31)
The surface area of the cuboid = 62 cm²
Thus, the surface area of the given cuboid will be 62 cm² whose dimensions are cm, 5 cm, and 2 cm.

What values of x

satisfy the system of equations {8x+9y=−36 x+7y=1}
Enter your answer as an ordered pair, like this: (42, 53)
If your answer includes one or more fractions, use the / symbol to separate numerators and denominators. For example, if your answer is (4253,6475),
enter it like this: (42/53, 64/75)
If there is no solution, enter "no"; if there are infinitely many solutions, enter "inf."
The solution to the system of equations is (x, y) = (-261/47, 44/47) as an ordered pair.
To solve the given system of equations:
Equation 1: 8x + 9y = -36
Equation 2: x + 7y = 1
We can use the method of substitution or elimination to find the values of x and y. Let's use the method of substitution:
From Equation 2, we can solve for x:
x = 1 - 7y
Substituting this value of x into Equation 1:
8(1 - 7y) + 9y = -36
8 - 56y + 9y = -36
-47y = -44
y = 44/47
Substituting the value of y back into Equation 2 to find x:
x + 7(44/47) = 1
x + 308/47 = 1
x = 1 - 308/47
x = (47 - 308)/47
x = -261/47
Therefore, as an ordered pair, the solution to the system of equations is (x, y) = (-261/47, 44/47).

Monica and her parents spent $170 on new swimsuits. Monica’s swimsuit cost $35. Her mom’s swimsuit cost twice as much as Monica’s. How much did her dad’s swimsuit cost?
━━━━━━━☆☆━━━━━━━
▹ Answer
Her dad's swimsuit costs $65.
▹ Step-by-Step Explanation
Since Monica's swimsuit is $35, we will subtract that from the total amount spent, $170.
$170 - $35 = $135
Since Monica's mom's swimsuit costs 2x Monica's we will multiply 35 * 2:
$35* 2 = $70
We will now add Monica's cost and her moms' cost:
$35 + $70 = $105
To find Monica's dads' cost, we will subtract 105 from 170:
$170 - $105 = $65
Her dad's swimsuit costs $65.

Complete the ordered pair. The graph of y = sin(2x - 1) passes through the point (___, 0).
The graph of y = sin(2x - 1) passes through the point (1/2, 0).
To find the missing value in the ordered pair, we need to solve the equation y = sin(2x - 1) for x when y = 0, since we are looking for the x-coordinate of a point on the graph when y is equal to zero.
Setting y = 0, we get:
0 = sin(2x - 1)
To solve for x, we can take the inverse sine of both sides:
sin⁻¹(0) = sin⁻¹(sin(2x - 1))
0 = 2x - 1 + kπ (where k is an integer)
Solving for x, we get:
x = (1 + kπ) / 2
Since we are looking for a specific point on the graph with a y-coordinate of zero, we can take k = 0 for simplicity to find the x-coordinate of the point. Thus, the missing value in the ordered pair is:
x = (1 + 0π) / 2 = 1/2

What equation of the line which passes through the point (-1, 2) and is parallel to the line y=x+4
Answer:
Thus, the equation of line for point (-1, 2) is y = x + 3.
Step-by-step explanation:
Answer:
The equation of the line is y = x + 3.
Step-by-step explanation:
A line that is parallel to y=x+4 and passes through the point (-1,2) will have the same slope as y=x+4. The slope of y=x+4 is 1, so the equation of the line will be in the form y = mx + b, where m=1. To find b, we can plug in x = -1 and y = 2 into the equation and solve for b.
y = mx + b
y = 1 * -1 + b
y = -1 + b
b = y + 1
b = 2 + 1
b = 3

What are the domain and range of the function f(x)=-x+3-2? domain: -3 -2 domain: -3 -3 range: y<-2 domain: x>-3 range:y>-2
For given function function f(x)=-x+3-2, the domain is x > -3 and the range is y ≤ 2. So, correct option is D.
The function f(x)=-x+3-2 is a linear function in the form y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is -1 and the y-intercept is 1. Therefore, the graph of the function is a straight line that intersects the y-axis at (0,1) and has a slope of -1, meaning that it decreases by 1 for every 1 unit increase in x.
The domain of the function is the set of all possible values of x for which the function is defined. Since there are no restrictions on the value of x in the equation f(x)=-x+3-2, the domain is all real numbers, or (-∞, ∞).
The range of the function is the set of all possible values of y that the function can output. In this case, the lowest possible value of y occurs when x approaches positive infinity, and the highest possible value of y occurs when x approaches negative infinity. Therefore, the range is all real numbers less than or equal to 2, or y ≤ 2.
So, the domain is x ∈ (-∞, ∞) and the range is y ≤ 2. Alternatively, the domain can also be expressed as x > -3, since that is the minimum value of x at which the function is defined.
Correct option is D.

y=-0.024x^2+0.0791x+4.873
The equation y = \(-0.024x^2\) + 0.0791x + 4.873 represents a quadratic function with a downward-opening parabol
The given expression is a quadratic equation in the form y = -0.024x^2 + 0.0791x + 4.873. Let's analyze its components and characteristics.
The equation represents a quadratic function, where x is the independent variable and y is the dependent variable. The coefficients in front of each term determine the shape, position, and direction of the graph.
The term with the highest power of x is -0.024x^2, which indicates a downward-opening parabola. The coefficient -0.024 determines the steepness of the curve. A negative coefficient means the parabola is concave down.
The term 0.0791x is the linear term and determines the slope of the line. A positive coefficient indicates an upward or positive slope. It affects the overall direction and position of the graph.
The constant term 4.873 is the y-intercept. It indicates the point at which the graph intersects the y-axis when x = 0.
To analyze the graph of the quadratic equation further, we can calculate the vertex. The x-coordinate of the vertex can be found using the formula x = -b/(2a), where a and b are the coefficients of x^2 and x, respectively. In this case, a = -0.024 and b = 0.0791. Substituting these values into the formula, we have x = -0.0791 / (2 * -0.024) ≈ 1.643. By substituting this x-coordinate into the equation, we can find the y-coordinate of the vertex.
Overall, the equation y =\(-0.024x^2 + 0.0791x\) + 4.873 represents a quadratic function with a downward-opening parabola. The specific properties, such as the vertex and other key points, can be determined by further calculations and analysis of the equation.

The Arizona Monsoon is a well-defined meteorological event (technically called a meteorological 'singularity') that occurs during the summer throughout the southwest portion of North America. During the winter time, the primary wind flow in Arizona is from the west or northwest—from California and Nevada. As we move into the summer, the winds shift to a southerly or southeasterly direction. Moisture streams northward from the Pacific Ocean and the Gulf of Mexico. This shift produces a radical change in moisture conditions statewide.
