Answer:

√74  or 74^(1/2)

Step-by-step explanation:

A (-2 , 4), C (3 , -3)

distance AC = √(x'-x)² + (y'-y)²

d = √(3 - -2)² + (-3 - 4)² = √5² + (-7)² = √74

The answer is the third option, because the range is -6 and the third option says its greater than or equal to -2.

Answer:

2(x – ½)(x + ½)

Step-by-step explanation:

2x² – ½

The above expression can be factorised as follow:

2x² – ½

2 is common to both 2 and ½. Thus,

2x² – ½ = 2[x² – ¼]

Recall

(½)² = ¼

Thus,

2[x² – ¼] = 2[x² – (½)²]

Difference of two squares

2(x – ½)(x + ½)

Therefore,

2x² – ½ = 2(x – ½)(x + ½)

Answer:

volume of a cone is 132 cubic centimeter.

The volume of a cone is defined as the amount of space or capacity a cone occupies. The volume of a cone formula is given as one-third the product of the area of the circular base and the height of the cone.

Volume of cone V = [tex]\frac{1}{3} \pi r^{2} h[/tex]

Given

Radius of cone r = 3 cm

Height of cone h = 14 cm

[tex]\pi[/tex] = [tex]\frac{22}{7}[/tex]

Volume of cone V = [tex]\frac{1}{3} \pi r^{2} h[/tex]

V = [tex]\frac{1}{3}[/tex] × [tex]\frac{22}{7}[/tex] × [tex]3^{2}[/tex] × [tex]14[/tex]

V = 22 × 3 × 2

V = 132 cubic centimeter

Hence, volume of a cone is 132 cubic centimeter.

Answer:

Rounding can be referred to as a replacement of a number with another number that is equivalent to it. Rounding can be used to shorten a given number without depriving it of its original value. For example, we have to round 56.89. We can round it as replacing it with 57 which is the closest value to 56.

Rounding numbers isn't that difficult task. In fact, it's quite interesting and easy to do. For rounding, all you are required to do is to figure out which decimal place of the number you want to round off. There are different methods to round off numbers. You can round off numbers to Half Up/Down, Round-Up/Down Round Half to Even/Odd, and So on. Anyhow, here, we are concerned with "To What Place You Want to Round Off a Number". This can be illustrated.

To know how rounding calculator works you just have to understand the way the numbers are rounded off to a particular decimal place. Following is a list of the places to which a number can be rounded off: 1. Ones 2. Tens 3. Hundreds 4. Thousands 5. Ten Thousands 6. Millions 7. Tenths (1 decimal place) 8. Hundredths (2 decimal place) 9. Thousandths ( 3 decimal place) 10. Ten Thousandths (4 decimal place) 11. Hundred Thousandths (5 decimal place) 12. Millionths (6 decimal place)

Answer:

Volume of the given sphere = 4.19 units³

Step-by-step explanation:

Volume of a sphere is given by the expression,

V = [tex]\frac{4}{3}\pi r^{3}[/tex]

Here, r = radius of the sphere

From the picture attached,

Radius of the sphere 'r' = 1 unit

Volume of the given sphere =  [tex]\frac{4}{3}\pi (1)^3[/tex]

                                               = [tex]\frac{4}{3}\pi[/tex]

                                               = [tex]\frac{4}{3}(3.14)[/tex]

                                               = 4.187

                                               ≈ 4.19 units³

Answer:

384 square inches

Step-by-step explanation:

The side is 10×5=50

There are 4 sides of equal surface area so we are at 200

The floor is 8×10=80 so we are at 280

The front is 8×5=40 and the back is the same so add another 40 so we are at 360

Add the little triangles which are 4×3=12 and you add the back as well so we get 384 square inches
