An experimental plane just after takeoff climbs with a speed of 500 km/h at an angle of 37 degrees with the horizontal. A) At what rate is the plane gaining altitude? (Hint, the vertical component of velocity is the rate that the plane is gaining altitude). B). What is the horizontal component of velocity for the plane?.

Answer:

Point B

Step-by-step explanation:

f (-4) is finding -4 on the y axis. Point B is (2, -4), hence the reason why it is the answer.

Answer:

-3

Step-by-step explanation:

y = 4x - 3

this equation is put in slope intercept form

y = mx + b

where m = slope and b = y intercept.

we want to find the y intercept

-3 takes the spot of b therefore the y intercept is -3

Add up to get the total number of marbles: (8 + 6 + 12 + 10) = 36

Then subtract the number of blue marbles from the total amount of marbles: 36 - 8 = 28.

28 signifies the amount of marbles that are NOT blue.

So the probability is: 28/36 = 0.77 = About 77%

The final answer is 7/9.

Volume is the space occupied by an object. The volume of the globe is 268.0825 in³.

The volume of the sphere is given by the formula,

[tex]\text{Volume of Sphere}= \dfrac{4}{3} \pi r^3[/tex]

We know that the diameter of the globe is reduced to half, therefore, the diameter of the globe,

[tex]\rm \text{New Diameter of the globe} = \dfrac{Diameter}{2} = \dfrac{16}{2} = 8\ inches[/tex]

Also, the radius of the globe is half of its diameter,

[tex]\rm Radius = \dfrac{Diameter}{2} = \dfrac{8}{2} = 4\ inches[/tex]

We know that the shape of a globe is spherical, also, we know the formula of the volume of the sphere, therefore, the volume of the globe can be written as,

[tex]\begin{aligned}\text{Volume of Globe}&= \dfrac{4}{3} \pi r^3\\\\& =\dfrac{4}{3} \pi (4)^3\\\\&=268.0825\rm\ in^3 \end{aligned}[/tex]

Hence, the volume of the globe is 268.0825 in³.

The shape of the cross-section is rectangle, 8 inches by 4 inches.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.

Now, from the figure we cut the figure from red line.

As the figure is a three dimensional figure called Cuboid.

We know that cuboid is formed by rectangle surfaces.

Then, the shape of the cross-section is Rectangle whose length is 8 inches and width 4 inches.

Right circular cylinder has its height as the straight line connecting centers of its top and bottom circle. The volume of given cylinder is: 5889.95 cubic feet.

Suppose that the radius of considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi \times r^2 \times h \: \rm unit^3[/tex]

For the given case, the considered right circular cylinder has these dimensions:

Its base diameter = 17.5 ft

Its height = 24.5 ft

Since radius is half of diameter, thus, radius of considered cylinder = 17.5/2 = 8.75 ft

Thus, using the formula for volume of right circular cylinder, we get:

[tex]V = \pi \times r^2 \times h \: \rm unit^3\\V \approx 3.14 \times (8.75)^2 \times (24.5) \approx 5889.95 \: \rm ft^3[/tex]

Hence, the volume of given cylinder is: 5889.95 cubic feet.

Answer:

There are 50 large boxes.

There are 65 small boxes

Step-by-step explanation:

First, "boxes of two sizes" means we can assign variables:

  Let x = number of large boxes

       y = number of small boxes

 "There are 115 boxes in all"    means    x + y = 115      [eq1]

Now, the pounds for each kind of box is:

    (pounds per box)*(number of boxes)

So,pounds for large boxes     +    pounds for small boxes      =    4125 pounds"the truck is carrying a total of 4125 pounds in boxes"

        (50)*(x)                   +              (25)*(y)                  = 4125    [eq2]

It is important to find two equations so we can solve for two variables.

Solve for one of the variables in eq1 then replace (substitute) the expression for that variable in eq2.  Let's solve for x:

   x = 115 - y          [from eq1]

 50(115-y) + 25y = 4125             [from eq2]

 5750 - 50y  + 25y = 4125           [distribute]

 5750 - 25y = 4125

 -25y = -1625

    y = 65   [divide both sides by (-25)]

  There are 65 small boxes.

Put that value into either equation (now, which is easier?) to solve for x:

  x = 115 - y

  x = 115 - 65

  x = 50

  There are 50 large boxes.

Answer:

D. Yes, because it passes the vertical line test

Step-by-step explanation:

the vertical line test is a test you do by drawing a vertical line through the graph of the function if more than one point from the function lies on the line it does not represent a function

in this graph at any part if you draw a vertical line it passes through one point only

Answer:

Okay so what you need to know here is for a graph to be considered a function it has to pass the vertical line test. This means that if a vertical line is moved across the graph and touches the graph at only one point, then it is considered a function. But if the vertical line touches the graph at more than one point, then it is not considered a function.

Step-by-step explanation:

But for this graph, I know it wouldn't be A, B, or C...... This is because this  and it touches the graph at only one point. We know the graph has to pass the vertical line test to be a function. But we can see here that it does because on the graph it only touches one point as you can see in that attachment. So, It would be D.... I'm pretty sure it is D though. Sorry if it's wrong. I tried to do what I could bcs I'm not really good at math lol

Please mark as brainliest pls and I have attached of graphs that pass the vertical line test to help you understand it better!

Answer:

Perimeter= 20 inches

Step-by-step explanation:

since the perimeter of a plane figure is distance round the shape, we add all the sides in order to get 20inches.

Perimeter= 4+5+4+4+3= 20incjes. That's for the perimeter.

Then area, we divide the shape into two portions sides A and B.

We find the area of side A which is a rectangle so, the are = Length×Breadth..

= 4×5 = 29cm².Side B is a triangle so it's area will be

Answer:

Total Perimeter = 30 in

Total Area: 30 in²

Step-by-step explanation:

First, do the perimeter of the triangle.

Equation: side+side+base = 3 + 4 + 5 = 12

Next is the perimeter of the rectangle.

Equation: 2(length + width) = 2·(5 + 4) = 18

Then, add the two perimeters:

12 + 18 = 30 in (Total Perimeter = 30 in)

Next, do the area of the triangle.

Equation: height • base/2 = 4 · 5/2 = 10

Finally, the area of the rectangle.

Equation: width • length = 4 · 5 = 20

Then, add the two areas:

10 + 20 = 30 (Total Area: 30 in²)

Step-by-step explanation:

I got the right answer

The cost to make the spinner is $132.50.

The spinner of the compass is two congruent isosceles triangles connected by their bases as shown in the diagram. The base of each of these triangles is 2 centimeters and the legs are 5 centimeters.

The area of each triangle is (1/2) * base * height = (1/2) * 2 * 5 = 5 square centimeters.

The total area of the spinner is 2 * 5 = 10 square centimeters.

The cost to make the spinner is 10 * $13.25 = $132.50.

Rounded to the nearest cent, the cost is $132.51.

Here is the calculation:

Area of each triangle = (1/2) * base * height = (1/2) * 2 * 5 = 5 square centimeters

Total area of the spinner = 2 * 5 = 10 square centimeters

Cost to make the spinner = 10 * $13.25 = $132.50
