-2 < AC < 8

Step-by-step explanation:

The last side has to be less than the sum of the other 2 sides, or less than 8. The only answer choice with this is the 3rd one.

Answer:

30.96 ft²

Step-by-step explanation:

area of square = 12 x 12 = 144 ft²

area of circle = (3.14)(6²) = 113.04 ft²

144 - 113.04 = 30.96 ft²

Answer:

x=50

y=40

p=130

Step-by-step explanation:

A whole circle is 360 degrees, so 270+40+x = 360. x=50.

Y is the same angle as the 40 degrees above it.

P is the same as y+90, so it's 40+90 = 130.

There is no picture but I'll help you find out:

The inequality is easy because an inequality says,

y > mx + b (This is just an example)

m = slope

b = y- intercept

What about the sign?

If the circle in the graph which is at the y-intercept (b) is OPEN than it's either < or > depending on where it's going, if it's going to the right on a number line than it's >, however if it goes left than it's <.

What about the AND EQUAL TO sign?

Well same rules apply, however if the circle is CLOSED than it should be      ≤ or ≥, same rules apply, if it goes right or left it's the same rule the only thing that changes is the and equal to, if circle is closed.

Example:

slope: 1/2

y-intercept: -9 (and the line is shaded to the right)

Open circle:

Equation: y > 1/2x - 9

Example 2:

slope: 3/4

y-intercept: -9 (is shaded to the left (less than))

(shaded)Closed circle:

Equation: y ≤ 3/4x - 9

Answer:

D

Step-by-step explanation:

Add 11 on both sides, therefore getting x is less than or equal to 11.  Now find the graph that fits the description - therefore D.  

Answer:

The resistance of the copper wire supplying electricity to this pump is 0.005 ohm

Step-by-step explanation:

Given

Per day cost of running centrifugal pump is $30

Charge of electricity is 9.7 cents per kilowatt hour

Total electricity power consumed

[tex]\frac{30}{0.097} \\309.278[/tex] kilowatt hour

Current flowing through the pump

[tex]= \frac{309.278}{240} \\= 1.288[/tex]A

Resistance of the pump

[tex]\frac{1.288}{240} \\0.005[/tex] ohm

The resistance of the copper wire supplying electricity to this pump is 0.005 ohm

Answer:

25.75 sq units

Step-by-step explanation:

Big triangle = 1/2 * 3.5 * 9 = 15.75

Tiny triangle = .5 * 2 * 2 = 2

Medium triangle = .5 * 2 * 5 = 5

square = 2 * 2

15.75 + 4 + 5 + 2

Using the unit circle, it is found that the value of y is given by:

[tex]x^2 + y^2 = 1[/tex]

At point P, we have that [tex]x = \frac{2}{5}[/tex], and hence, we have to find the value of y.

[tex]x^2 + y^2 = 1[/tex]

[tex]\left(\frac{2}{5}\right)^2 + y^2 = 1[/tex]

[tex]\frac{4}{25} + y^2 = 1[/tex]

[tex]y^2 = 1 - \frac{4}{25}[/tex]

[tex]y^2 = \frac{21}{25}[/tex]

[tex]y = \pm \sqrt{\frac{21}{25}}[/tex]

[tex]y = \pm \frac{\sqrt{21}}{5}[/tex]

It’s :lim f(x)=85 and lim f(x)=120

The limit of the given functions f(x)=85 and lim f(x)=120.

We have given that,

Answer:

[tex]\frac{9}{80}[/tex]

Step-by-step explanation:

So there is 40marbles in total

The probability of picking a red marble first is [tex]\frac{10}{40}[/tex] because there is 10 red marbles out of 40 total marbles

Then you replace it and I'm going to assume that you put the red marble back.

Then you would still have 40 marbles and the probability of picking a blue one is [tex]\frac{18}{40}[/tex] because there is 18 blue marbles.

Then you multiply [tex]\frac{10}{40}[/tex] and [tex]\frac{18}{40}[/tex] and that is [tex]\frac{9}{80}[/tex]

Answer:

1000 times larger.

Step-by-step explanation:

Answer:

1000 ( divide 5000 by 5 )

Step-by-step explanation:

The endpoints of the diameter are A(-4,1) and B(4,2) . For finding the equation of circle we need to find the centre and the radius.

Coordinates of centre can be find out by the midpoint formula.

[tex] \implies Center = \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\implies Centre = \bigg(\dfrac{-4+4}{2},\dfrac{1+2}{2}\bigg)\\\\\implies \boxed{\boxed{Centre = (0 , 1.5)}}[/tex]

Now the measure of radius can be obtained by half the distance between them.

[tex]\implies D = \sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}\\\\\implies D =\sqrt{ (4+4)^2+(2-1)^2}\\\\\implies D = \sqrt{ 64 + 1 }\\\\\implies D =\sqrt{65} \\\\\implies \boxed{\boxed{ Radius = \dfrac{\sqrt{65}}{2} }}[/tex]

We know the general equation of circle as ,

[tex]\implies (x-h)^2+(y-k)^2= r^2[/tex]

[tex]\implies (x-0)^2+ (y-1.5)^2 = \bigg(\dfrac{\sqrt{65}}{2} \bigg)^2\\\\\implies x^2 + (y-1.5)^2=\dfrac{65}{4} \\\\\implies\boxed{\boxed{ 4x^2+4(y-1.5)^2 = 65 }}[/tex]
