x = 41 cm
Here is why:
For this question we have to use the pythagorean theorem, which is used for right triangles. The hypotenuse will always be the last in this theorem.
[tex]a^2+b^2=c^2[/tex]
Plug in.
[tex]9^2+40^2=c^2[/tex]
[tex]81+1,600=c^2[/tex]
Add together.
[tex]1,681=c^2[/tex]
Now we will find the square root of 1,681, since c is squared.
[tex]\sqrt{1,681}[/tex]
= 41 cm

A cube has a net with area 600 in2. How long is an edge of the cube?
Answers
Answer : The length of an edge of cube is, 10 inches.
Step-by-step explanation :
The formula used for area of cube is:
Area of cube = [tex]6a^2[/tex]
where,
a = edge
We are given that:
Area of cube = [tex]600in^2[tex]
Now put all the given values in the above formula, we get:
Area of cube = [tex]6a^2[/tex]
[tex]600in^2=6a^2[/tex]
[tex]a=10inches[/tex]
Therefore, the length of an edge of cube is, 10 inches.

Find the perimeter of the parallelogram with these vertices.(-2,2) ,(-2,-2) ,(6,-1) ,(6,-5)
Answers
The perimeter of the parallelogram with these vertices.(-2,2) ,(-2,-2) ,(6,-1) ,(6,-5) is 26 units.
In this explanation, we will find the perimeter of a parallelogram using its vertices' coordinates. The perimeter is the total length of all sides of the parallelogram. To find it, we'll apply the distance formula from coordinate geometry.
A parallelogram is a four-sided polygon with opposite sides parallel and equal in length. To calculate its perimeter, we need to find the lengths of all four sides and then add them together.
Step 1: Find the length of side AB.
Using the distance formula, the length of AB is
= √((-2 - (-2))² + (2 - (-2))²)
= √(0² + 4²)
= √16
= 4 units.
Step 2: Find the length of side BC.
Again, applying the distance formula, the length of BC is
= √((-2 - 6)² + (-2 - (-1))²)
= √((-8)² + 1²)
= √(64 + 1)
= √65 units.
Step 3: Find the length of side CD.
By using the distance formula, the length of CD is
= √((6 - 6)² + (-1 - (-5))²)
= √(0² + 4²)
= √16
= 4 units.
Step 4: Find the length of side DA.
Once more, applying the distance formula, the length of DA is
= √((6 - (-2))² + (-5 - 2)²)
= √((8)² + (-7)²)
= √(64 + 49)
= √113 units.
Step 5: Calculate the perimeter.
The perimeter is the sum of all four sides:
= AB + BC + CD + DA
= 4 + √65 + 4 + √113
≈ 4 + 8.06 + 4 + 10.63
≈ 26 units.
Therefore, the perimeter of the parallelogram defined by the given vertices is approximately 26 units.

Suppose a circle with center (1, −3) passes through point (1, −1). Which equation represents the circle?
Answers
Answer:
(2,-4)
Step-by-step explanation:
Answer:
It is C) (x − 1)^2 + (y + 3)^2 = 4
Step-by-step explanation:
The radius is the distance between the center and the point on the circle.
Center: (1, −3); Point: (1, −1)
Distance formula: d = square root of {(x2 - x1)^2 + (y2 - y1)^2}
r = square root of {(1 − 1)^2 + (−1 + 3)^2 }
r = square root of {0 + 4 } = 2
(x − h)^2 + (y − k)^2 = r2 ----> (x − 1)^2 + (y + 3)^2 = 4

A rocket is launched from a tower. The height of the rocket, y in feet is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=-16x^2+165x+78
Answers
To find the maximum height reached by the rocket, we need to find the vertex of the quadratic equation. The maximum height is approximately 270.6 feet.
Explanation:To find the maximum height reached by the rocket, we need to find the vertex of the quadratic equation. The equation is in the form of y = ax^2 + bx + c, where a = -16, b = 165, and c = 78. The x-coordinate of the vertex is given by -b/2a, and the y-coordinate is the value of y when x is the x-coordinate of the vertex. Plugging in the values, we find that the maximum height reached by the rocket is approximately 270.6 feet.

To solve the expression [6+9 x (4-2)] ÷ 4+2, use the order of operations (PEMDAS), resulting in the answer 8.
The subject of this question is Mathematics and it involves the steps of evaluating the given mathematical expression, [6+9 x (4-2)] ÷ 4+2, which is a task typically encountered in middle school.
To solve this problem, we employ the Order of Operations, which can be remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Solve the expression in the parentheses: 4-2 = 2
Multiply 9 by the result from the parentheses: 9x2 = 18
Add 6 to the product: 6+18 = 24
Divide the sum by 4: 24 ÷ 4 = 6
Add 2: 6+2 = 8
Thus, [6+9x(4-2)] ÷ 4+2 equals 8.

Geometric Sequence:
Identify the common ratio: The common ratio is found by dividing any term by the previous term in the sequence. In this case, the common ratio is 0.5 (14/28 = 0.5).
Find the 8th term: Using the formula for the nth term of a geometric sequence [tex](a_n = a_1 * r^{(n-1)}),[/tex] plug in [tex]a_1 = 28[/tex], r = 0.5, and n = 8 to find the 8th term.
The 8th term of the sequence will be equal to 1.75.

If the minute hand is 5.25 in. long. What is the circumference of the circle?
Answers
In this example, the minute hand is our radius, because it’s half the internal length of the circle.
The circumference of the circle is equal to pi x diameter.
Since diameter is twice the radius, we can do 5.25 x 2 = 10.5.
From there, we can substitute and solve.
pi x diameter
pi x (10.5)

Graph a line with a slope of 2/5 with a point of -2/4
Answers
Answer:
See photo
Step-by-step explanation:
To graph a straight line, you need two points, then connect them.
Your first point is given: (-2, 4)
To get the next point, use the slope.
The slope 2/5 is written rise / run.
Rise is the number of units going up, or down if it's a negative number.
Run is the number of units rightwards.
Take the first point (-2, 4), and add the rise to the y-value. Add the run to the x-value.
x = -2, run = 5
New x = 3
y = 4, rise = 2
New y = 6
New point: (3, 6)
Plot the two points on the grid, then connect the dots.
Remember to put arrows at both ends of your graph.

Answers
Answer:
See explanation.
Step-by-step explanation:
Hello, your question is not very clear.
Based on the limited information, this is how we go about it.
If the rate at which people learn about a secret is directly proportional to the number of people who know the secret and 20 people know it on day 2, then the unit rate is 10.
That is the constant of proportionality is 10.
The direct variation equation is
[tex]y = 10x[/tex]
We want to find how long it will take take for a whole school population of 4000 people to know the secret.
We put y=4000 and solve for x.
[tex]4000 = 10x[/tex]
[tex]x = 400[/tex]
Hence it will take 400 days.
