Mathematics

Irina18 [472]3 years ago

Answer:

4 x n + 2 = -18 or

N = -5

Step-by-step explanation:

I assume you mean two, so

When it says “than” in the question, you put it before the number (so example

5 more than x = 7

X + 5 = 7)

So,

4 x n + 2 = -18

-2

4 x n = -20

/4. /4

N = -5

2x-5y=-28 find the value of y when x equals -19
nydimaria [60]
<h3>Question:</h3>

2x-5y=-28 find the value of y when x equals -19

<h3>Answer:</h3>

Y = - 2

<h3>Step-by-step explanation:</h3>

First you plug in -19 where x is 2(-19)-5y = -28

Remove parentheses               -2 · 19-5y= -28

Multiply -2 by 19                       -38-5y= -28

Add 38 to both sides               -5y = 10

Divide both sides by -5            [tex]\frac{-5y}{-5} =\frac{10}{-5}[/tex

you will get -2 which is the answer.


Hope this helped!

If the infinite curve y = e−6x, x ≥ 0, is rotated about the x-axis, find the area of the resulting surface.
Ber [7]
The area:
A = 2  \pi  \lim_{b\to \infty} ( \int\limits^\infty_0 {e ^{-6x} } \, dx)
Substitution: u = - 6 x
du = - 6 dx
dx = -1/6 du
∫ -1/6 e^(u) du = - 1/6 e^(u) = - 1/6 e^(-6x)
A = -1/6 * 2 \pi   \lim_{b \to \infty}  (\int\limits^\infty_0 \, e ^{-6b} db) = \\ =- \pi /3 * ( e ^{-\infty} -e ^{0}) =  \\ = - \pi /3 * ( - 1 ) =
=  π / 3

2. Dora and Ron share £50 in the ratio 3:7.
yaroslaw [1]
£15

If you add the two ratios together you get 10. Which means that the £50 is made up of 10 pieces. To get Doras amount you have to divide 50 by 10 which is five, and then times the number by how many pieces Dora has, which would be 5x3=15
