When you divide a number by a fraction, you should multiply the number by the reciprocal of the fraction. So if you make 1 1/3 an improper fraction you get 4/3. When you multiply 24 by the reciprocal, which is 3/4, you multiply it by the numerator and divide it by the denominator. So
(24 x 3) / 4
72 / 4

Help!The _______ is the key to deriving the equations for four conic sections.

Midpoint formula

Pythagorean theorem

Distance formula

Answers

Answer:

The correct answer is Distance Formula

Step-by-step explanation:

The shape of the conics in the conic section is characterized by a factor called eccentricity of the conic and further derivations are done using this factor.

And the eccentricity of the conics can be calculated by taking the center-to-focus distance and dividing it by the semi-major axis distance. So, to find the eccentricity of the conic, one must know how to apply the distance formula.

Hence, Distance Formula is the key to deriving the equations for conic sections

Answer:

answer is Distance Formula

What is the slope of the line that goes through (6,5) and (3,1)?Answers:
A.3/4
B.-3/4
C.4/3
D.-4/3

Answers

Solving the slope,
m = (y2 - y1)/(x2 - x1)
m = (1 - 5)/(3 - 6)
m = (-4)/(-3)
m = 4/3

PLS HELP ME OUT REWARD GUARANTEE!!!!!!!!!!!!!The fat content for seven different sandwiches at a restaurant is 42, 61, 13, 9, 12, 42, and 62. Find the mean, median and mode of the fat contents.

Answers

Mean: subtract the smallest number from the biggest number...62-9=?Median: the middle number, order the numbers from smallest to biggest....Mode: the number that is repeated the most...This should help you. I do not want to give you the answers. I want you to do them yourself with the instructions I gave you and then come back and post them when you are done so I may check them. Okay?

Mean: $\bar{x} = (x_(1) + x_(2) + x_(3) + x_(4) + x_(5) + x_(6) + x_(7))/(n)$
$\bar{x} = (42 + 61 + 13 + 9 + 12 + 42 + 62)/(7)$
$\bar{x} = (241)/(7)$
$\bar{x} = 34(3)/(7)$

Median: 9, 12, 13, 42, 42, 61, 62
42

Mode: 42

Substitution and elimination are two symbolic techniques used to solve linear equations. For example, if it is easy to set up an equation for substitution where 1 variable is on 1 side, then use that; For example, 4y=16+4x, you can easily divide by 4, get y=4+x (or y=x+4), and plug that into the other equation. In other cases where it may not be so easyFractions/decimals, etc., then you would probably rather use elimination.1) The substitution method. This method is best utilized when one of the variables in one of the equations has a coefficient of 1 or -1, otherwise you will introduce fractions. Substitution can also be used for nonlinear systems of equations.(2) Linear combinations also called the elimination method, multiplication and addition method, etc... My personal favorite as it can be done efficiently. It generalizes well to larger systems and is the underpinning of various other solution methods.As the name implies it requires the equations to be linear.You need to know both and be comfortable switching between them.Can we get one for the elimination method too?Also, can you solve the same problem using either of the two techniques?
