Fails the vertical line test

Answer:

No a circle is not a function.

Step-by-step explanation:

A function is a mapping from 1 set to another

eg, 1 to 2

3 to 4

while a circle it maps the same point to another

meaning it has more than two input/output

(if u get what i mean)

Answer:

-7x-4y+4y=-44+4y

Answer:

[tex]Area = 287\ in^2[/tex]

Step-by-step explanation:

Given

[tex]Length = 20.5[/tex]

[tex]Space = 4.25[/tex]

[tex]Panels = 3[/tex]

See attachment

Required

The area of one panel

From the attachment, the total width is 50.5in.

i.e.

[tex]Total\ Width = 50.5[/tex]

Given that there are 2 spaces between the 3 panels and each space has a length of 4.25 in.

The reduced width is:

[tex]Reduced\ Width = 50.5 - 2 * 4.25[/tex]

[tex]Reduced\ Width = 42[/tex]

At this point, we can calculate the width of one panel by dividing the reduced width by the number of panels (3).

[tex]Width = \frac{42}{3}[/tex]

[tex]Width = 14[/tex]

The area of one is:

[tex]Area = Length * Width[/tex]

[tex]Area = 20.5 * 14[/tex]

[tex]Area = 287\ in^2[/tex]

Answer:

Answer:

Check pdf

Step-by-step explanation:

The impulse of the given force is required.

The impulse of the force which is being exerted on an object of 75000 kg is 100000 Ns.

F = Force exerted on a body = 20000 N

t = Time the force was exerted for = 5.00 s

When finding the impulse of a force the mass of the object the force is being applied to does not matter. The only thing that can affect the force is if another force is being applied by the object which here is not doing so.

Impulse is given by

[tex]J=Ft\\\Rightarrow J=20000\times 5.00\\\Rightarrow J=100000\ \text{Ns}[/tex]

Answer:

He should buy two of the 5-pound bag.

Step-by-step explanation:

The cook needs 10 pounds of flour.

He wants to spend the least amount of money.

First option is a 5-pound bag for $2.89 each.

He can get 2 of the 5-pound bag which equals 10 pounds of flour for 2 x $2.89 = $5.78

Second option is a 2-pound bag for $1.59 each.

He can get 5 of the 2-pound bag which equals 10 pounds of flour for 5 x $1.59 = $7.95.

Second option is $2.17 costlier than the first option.

So, he should go for 2 of the 5-pound bag in order to spend the least amount of money while shopping for 10 pounds of flour.

So [tex]\sqrt{5}[/tex] is between [tex]\sqrt{4} and \sqrt{9}[/tex] so it is between 2 and 3

If that is a negative [tex]\sqrt{30}[/tex] then it is between square root of 25 and 36, which would be -5 and -6

Answer: 225 square feet

Step-by-step explanation:

We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.

Area of triangle 1 = 1/2 base × height

= 1/2 × 12 × 8

=96/2

=48

Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)

Area of triangle 3 = 1/2×base×height

= 1/2 × 6 ×9.5

= 57/2

=28.5

Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)

Area of the rectangle = length×breadth

=12 × 6 =72

Total surface area = addition of all the areas of the triangles and the rectangle

Total surface area= 48+48+57+57+72 = 225

Therefore, the total surface area is 225 square feet

Answer:

The answer is below

Step-by-step explanation:

A linear function graph can be represented by:

y = mx + b; where m is the slope and b is the y intercept, x is the independent variable and y is the dependent variable.

a) From the graph we can see the graph passes through the point (0, 100) and (20, 400). Hence we can use the following formula to find the equation:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-100=\frac{400-100}{20-0}(x-0)\\\\y-100=15x\\\\y=15x + 100[/tex]

b) An example of real life linear function is the energy consumed per day in kWh. Let us assume 5 kWh is consumed each day by the person. Since the independent variable is the days, it would be on the x axis, while the dependent variable (energy consumed) would be on the y axis.
