Write the equation of the line in fully simplified slope-intercept form.

The answer is C.

Here is the formula for volume of cone:

[tex]\frac{1}{3} \pi r^{2} h[/tex]

where r is the radius and h is the height.

[tex]\pi r^{2}[/tex] is the area of the "base" or the fomula for calculating the area of a circle.

In your question, the height is given, but you don't know the radius. However, it could be found using the circumference of 8.4pi cm.

The formula for the relationship between circumference, diameter, and the constant pi:

[tex]C =\pi d[/tex]

where C is the circumference and d is the diameter of the circle.

Substitute the numbers in:

[tex]8.4 \pi = \pi d[/tex]

Remove [tex]\pi[/tex] from both sides of the equation:

[tex]d=8.4[/tex]

Diameter is the length across the circle, while radius is half of diameter.

Hence, [tex]r =4.2[/tex]

Now that you have all the "information" you need to calculate the cone's volume, substitute the numbers into the formula:

[tex]\frac{1}{3} \pi * 4.2^{2}* 14[/tex]

You should get  [tex]82.32\pi cm^{2}[/tex]  as your answer. The [tex]\pi[/tex] is left alone because the question stated "in terms of pi", but if that weren't stated pi should be replaced with 22/7 or 3.14 depending on the question.

I hope this clears up any confusion you might have! If not, feel free to leave a comment with your question.

last  bubble one i guess ok

The answer is a and b.

Here's the way to check:

Since all the numbers follow a constant sequence, it is possible to use division. Minus the first term, then divide it by the pattern of the sequence.

For a, 512 - 8 = 504

The pattern from a is each number is increased by 7. So,

504 ÷ 7 = 72

The number itself you count is not important. The point is that the number could be divided fully without remainder. This means 512 will appear in the sequence.

Repeat the above steps for b and c:

512 - 23 = 489

489 ÷ 3 = 163

It can be divided without remainder, 512 appears in this sequence.

512 - 12 = 500

500 ÷ 12 = 41.66666

Since C is a decimal ( there is remainder ), the number 512 does NOT appear in the sequence.

However, if you want to know the logic of WHY this works, I won't be able to give you a satisfying answer. Hope this helps you.

Answer:

B.

Step-by-step explanation:

Both equations use x squared

Answer:

The common facor is x-3.

Step-by-step explanation:

The first expression can be factored with a difference of squares, x+3 and x-3. You can check that by multiplying them together to get x²-9. Knowing that you need a common factor, one that works for both expressions, you can immediately eliminate A and B. The second expression, x²-5x+6, has to share one of these two factors. To factor this, you find the numbers that multiply to the c term and add to the b term. (Ax²+bx+c) so b is -5 and c is 6. All you have to do is find out which two numbers add to -5 and multiply to 6. You start with factors of 6, which are +-6 and +-1, and +-3 and +-2. Say you try 6 and 1 first. The b term is negative, so these two added have to add to a negative number, which means positive 6 and positive 1 won´t work. The only way to add to -5 is to add 1 to -6 or -6 to 1, but multiplying those together gives you -6, and you need positive 6 in the c term. That leaves you with -2 and -3. they add to -5, and multiply to -6, which means that your common term is x-3. Test this by expanding your result, (x-2)(x-3), if you get the original expression theyre both factors.

Step-by-step explanation:

Answer:

I would have to say J.

Step-by-step explanation: Now a square has 4 sides, all equal as well. (I am on PC so I cant do the little 2 on J.) so 2 times little 2 is 4, because with these for example, 2 times little 3 would be 2 times 2 times 2. So 2 times little2 -9 is the most reasonable answer!

Explanation

Separate the values with the variables and add them together, the same case for those without the variables.

Answer:

1. transversal: (of a line) intersecting a system of lines.

2. acute angle: Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees. Learn about angles types and see examples of each.

3. alternate extirior angles: When two lines are crossed by another line (called the Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal.

4. congruent: in agreement or harmony.

5. congruent figures: Congruent figures are geometric figures that have the same shape and size. That is, if you can transform one figure into another figure by a sequence of translations , rotations , and/or reflections , then the two figures are congruent.

6. isosceles triangle: In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case

7. obtuse angle: An obtuse angle ...” ... An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees. So, an angle of 190 degrees would be reflex.

8. right angle: an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.

9. remote interior angle: Remote interior angles are angles that don't share a vertex or corner of a triangle with the exterior angle. The measure of the exterior angle equals the sum of the two remote interior angles.

10. same-side interior angles:Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

11. corresponding angles: When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.

12. corresponding parts: corresponding parts. Sides or angles that occupy the same relative positions in similar polygons. congruent triangles. 2 triangles are congruent if and only if all pairs of corresponding sides and angles are congruent.

13. equilateral angle: In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

14. exterior angle: 1 : the angle between a side of a polygon and an extended adjacent side. 2 : an angle formed by a transversal as it cuts one of two lines and situated on the outside of the line.

15. scalene triangle: A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.

16. similar figures: Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor .

17. striaght figures: A line that does not curve. In geometry a line is always straight (no curves).

18. theorem: a general proposition not self-evident but proved by a chain of reasoning; a truth established by means of accepted truths.

Answer:

Step-by-step explanation:

Answer:

A: 479.94/6

B: D, 56.79

C: 79.99 and 56.79

D: Obviously 79.99 is greater than 56.79 so the slope in question A is greater than the slope in B (C)

Step-by-step explanation:

Question A:

For this one we will let x= nights in a hotel and y=cost

We can then just pick two points on the table and plug in the numbers to the formula above

Let's pick the first and last one

our two ordered points are (0,20) (6,499.94)

We can plug this in and get

(499.94-20)/(6-0) which simplified to 479.94/6

Question B:

This equation is in slope intercept form

Slope intercept form is as follows

y=mx+b

where m is the slope and b is the y intercept

we can see that the m value is 56.79 which means D is the answer

Question C:

This is pretty easy

First divide 99.8/2 and get 49.9 and the other answer is just 56.79

Answer:

A: 479.94/6

B: D, 56.79

C: 79.99 and 56.79

D: Obviously 79.99 is greater than 56.79 so the slope in question A is greater than the slope in B (C)
