One fifth of a number plus five times that number is equal to seven times the number less 18. find the number.

Schach [20]

OK. First we have to figure out names for all the numbers you mentioned.

The mysterious number . . . . . call it Q
One fifth of the number . . . . . 0.2 Q
Five times the number . . . . . . 5 Q
Seven times the number . . . . 7 Q

(One fifth plus five times the number) . . . 5.2 Q
(Seven times the number less 18) . . . . . . 7 Q - 18

You said that these last two things are equal,

so I can write . . . . . . . . . . . . . . . . . . 7 Q - 18 = 5.2 Q

Now, subtract 7Q from each side . . . -18 = -1.8 Q

Divide each side by -1.8 . . . . . . . . . . 10 = Q

A parabola can be drawn given a focus of (1,3) and a directrix of x = -7. What

irakobra [83]

Answer:

Below.

Step-by-step explanation:

The parabola will open to the right and will be symmetrical about y = 3.

The vertex is halfway between x = 1 and x = -7 making it at (-3, 3).

The p value is the distance between the vertex and the focus - here it is 1 - -3

= 4.

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point C (-2, 0)

Point D (3, 5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(3+2)^2+(5-0)^2}$
[√Radical] (Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(5)^2+(5)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{25+25}$
[√Radical] Add: $\displaystyle d = \sqrt{50}$
[√Radical] Simplify: $\displaystyle d = 5\sqrt{2}$
[√Radical] Evaluate: $\displaystyle d = 7.07107$
Round: $\displaystyle d \approx 7.07$
