Work out the curved surface area of the frustum
A frustum is made by removing a small cone from the top of a large one.
In the diagram shown, the height of the small cone is half the height of the large cone.
Work out the curved surface area of the frustum.

Answer:

y>3.00833...

Step-by-step explanation:

Answer:

[tex]y=-2x+3[/tex]

Step-by-step explanation:

Equation of straight line in slope intercept form is given as

[tex]y=mx+b[/tex]

Here

Slope of line m=-2 (for every one step on x-axis line going down 2 step on y-axis)

y-intercept b=3

[tex]y=-2x+3[/tex]

Answer:

because the coefficient is positive

Step-by-step explanation:

hope it helps

Answer:= 87.50m

Step-by-step explanation: base × height ÷2

                                                25 ×  7     ÷    2

                                                175      ÷ 2  

                                              =   87.50

Answer:

y=-1/3x+10

Step-by-step explanation:

y=3x+1

The line perpendicular would have a negative reciprocal of the slope of 3 which means that you would add a negative sign and then flip 3/1 into 1/3 resulting in -1/3 as the slope.

To find the line that passes through the point (6,8) you would plug the values into the equation y=mx+b

m=-1/3x as found above

6 is the x-value and 8 is the y-value

8=(-1/3)(6)+b

8=-2+b

Add 2 on both sides and you get b to equal 10  

Answer:

B) 45,523

Answer:

Speed of Puck is 18 m/s

Step-by-step explanation:

Mathematically;

speed = distance/ time

The puck traveled a distance of 27 m in 1.5 seconds

The speed of the puck is thus;

27/1.5 = 18 m/s

Note:

 - When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.

Equation at the end of Step 1:

Note:

 - The x(d) stays the same since the 6 was positive and we plugged it in making it negative, so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.

 - The y(k) changes from [tex]+(-6)[/tex] to [tex]-6[/tex] because when a [tex](+)[/tex] and [tex](-)[/tex] are next to each other, the rule is [tex]+<-[/tex]. The Minus always wins in this type of problem situation.

So the answer is c, [tex]\bold{y=\frac{3}{x-6}-6}[/tex].

Answer:

The value of x = 0    

Step-by-step explanation:

Given

To determine

The value of x = ?

If we closely observe the value of the y-coordinate of the image B'(x, 20), we can see that the y-coordinate of the image B' is 4 times the y-coordinate of the original point (0, 5).

i.e. y → 5×4 =20

It means the coordinates of the image B'(x, 20) can be determined by dilating the original point (0, 5) by a scale factor of 4.

Thus, the x-coordinate of B'(x, 20) can also be obtained by multiplying the x-coordinate of B(0, 5) by 4.

i.e. x → 4×0 = 0

Thus, the rule of dilation is:

P(x, y) = P'(4x, 4y)

Hence,

B(0, 5) → B'(4(0), 4(5)) → B'(0, 20)

Thus,

The value of x = 0           ∵ 0×4 = 0

Answer:

32%

Step-byentrepreneurstion:

The first step is to calculate the decrease

= $84 - $57.12

= $26.88

Therefore the decrease can be calculated as follows

= 26.88/84 ×100

= 0.32×100

= 32%

Hence the bill decreased by 32%

Answer:

There are 213.36 centimeters in 7 feet.

Step-by-step explanation:

It is given that:

1 inch = 2.54 cm

We have to find centimeters in 7 feet.

We will convert feet to inches.

1 feet = 12 inches

7 feet = 12*7 = 84 inches

Now,

1 inch = 2.54 cm

84 inches = 2.54 * 84

84 inches = 213.36 cm

Therefore,

There are 213.36 centimeters in 7 feet.

Answer:

32.4 cm²

Step-by-step explanation:

Given the parallelogram ABCD ; with AB = 7.2 cm

Perpendicular from C on AB is the height of the parallelogram = 4.5 cm

Using the relation fir the area of a parallelogram :

Area of a parallelogram = base * height

Area of a parallelogram = 7.2 cm * 4.5cm

Area of parallelogram = 32.40cm²

Hence, Area of parallelogram is 32.4 cm²
