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.

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.

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.

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

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

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.

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.

Step-by-step explanation:

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

Answer:

Domain: (-4, ∞)

Range: (-∞,∞)

Step-by-step explanation:

Domain is all of your possible x values and range is all of the possible y values. I may have wrote the brackets wrong but the values are wright.

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)

If we’re representing pi as 3.14, the answer will come out to 32.97.

If we’re representing pi in its calculator function form, it’ll be roughly 32.986723.

So either of those could be your answer depending on how pi is represented.

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:

Sum

Step-by-step explanation:

Its right

The degree of the product is the sum of the degrees of the factors.

The degree of a polynomial is the highest power of the variable in the polynomial.

The length of a box is (4x -1)

The width of a box is  x

The height of a box is x³

The volume of the box is determined by

Length * Width * Height

Volume =  (4x -1) * x * x³

Volume = 4x⁵ - 4x⁴

The degree of length is 1

The degree of width is 1

The degree of height is 3

The degree of Volume = 5

The degree of the product is the sum of the degrees of the factors.

Step-by-step explanation:

You would use the Pythagorean Theorem to solve it which would be a^2 + b^2 = c^2 and a would be 800 and b would be 650 in this circumstance you would try to find C which would be glenn blvd.

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, h² = 1062500

or, h = 1030.77 (approx)

Hence,

The length of the Glenin Blvd road is 1030.77 m.

Answer:

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.

Step-by-step explanation:

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.
