What is the greatest common factor of 24s^3,12s^4,18s
Answer:
6s
Step-by-step explanation:
Answer:
6s
Step-by-step explanation:
24s^3 = 2 * 3 * 4 * s *s * s
12s^4 = 2 * 2 * 3 * s * s * s * s
18s = 2 * 3 * 3 * s
As we can see, the common factors that both 24s^3, 12s^4, and 18s have are 2, 3, and s. Multiply these common factors, and you get 2 * 3 * s = 6s, which is the greatest common factor of 24s^3, 12s^4, and 18s.

Answer:
234.3
Step-by-step explanation:
You use Law of Cosines:
a^2 = b^2 + c^2 - 2bc(cosA)
Plug in the values
a^2 = 400^2 + 375^2 - 2(400*375)(cos35)
a = sqrt(160000+140625-300000(cos35))
a = sqrt(300625 - 300000cos(35))
a is approx. 234.263498466, which rounds to 234.3

Find the perimeter of the figure to the nearest hundredth.
Answer:
60.00 in^2
Step-by-step explanation:
First focus on the area ABOVE the dotted line. The shape here is that of a trapezoid. The two leg lengths are 12 in and 18 in (18 in is the diameter). At the far right of this trapezoid we can picture a triangle of base 3 in, height h and hypotenuse 5 in. Using the Pythagorean Theorem, we get h = 4 in.
This 4 in measurement is the width of the trapezoid. Thus, we are now ready to apply the formula for the area of a trapezoid: A = (average length of legs)*(width).
Here that area comes out to
12 in + 18 in
A = --------------------- * 4 in = 15 in*4in = 60 in^2, or (to the nearest hundredth)
2 60.00 in^2
The total area of the figure is 77 square centimeters. The overall height of the figure is 9 centimeters.
Drag the correct measurements to label the unknown lengths in the figure.
Answer:
5cm and 10 cm
Step-by-step explanation:
Since the overall height of the shape is 9 and the base of the triangle shaped piece is 6, the area of that piece is 6*9/2=27 units. Subtracting this from the total of 77, you know that the rectangle must have an area of 50 units. Out of the options that you have to drag, the only two that multiply together to be 50 units are 5 for the shorter side and 10 for the longer side. Hope this helps!
The correct measurements to label the unknown lengths in the figure 5 cm and 10cm.
What is Area of Rectangle?The area of Rectangle is length times of width.
The overall height of the shape is 9 cm
The base of the triangle shaped piece is 6
The area of triangle is 1/2×base×height
Area of that piece is 6×9/2=27 units.
Now let us subtract this from the total area
Total is 77 units
the rectangle must have an area of 50 units.
the only two that multiply together to be 50 units are 5 for the shorter side and 10 for the longer side.
Hence, the correct measurements to label the unknown lengths in the figure 5 cm and 10cm.

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
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.

Graph a line with a slope of 2/5 with a point of -2/4
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.

The length of the Glenin Blvd road is 1030.77 m.
Step-by-step explanation:
Given,
Length if Main street (b) = 800 m
Length of Oak street (l) = 650 m
To find the length of Glenin Blvd (h) road
The given diagram forms a right angle triangle where Main street is the base, Oak street is the height and Glenin Blvd road is the hypotenuses.
Formula
Pythagoras theorem: b²+l² = h²
So,
h² = 800²+650²

or, h = 1030.77 (approx)
Hence,
The length of the Glenin Blvd road is 1030.77 m.
Suppose a circle with center (1, −3) passes through point (1, −1). Which equation represents the circle?
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

Find the perimeter of the parallelogram with these vertices.(-2,2) ,(-2,-2) ,(6,-1) ,(6,-5)
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.

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]

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)
