4 0

Answer:

Step-by-step explanation:

Think about your 10 and 15 times tables starting from 1, when you find two similar numbers that is your least common multiple. It is important not to mix this up with least common factor (which would be 5)

10:

2 * 10 = 20

3 * 10 = 30

4 * 10 = 40 etc etc

15:

2 * 15 = 30

3 * 15 = 45

The common number here is 30, it is the lowest common multiple

First Draw the graph (If you want)

Tan is what we have to use because TAN = Opposite / Adjacent

TanA=2/4

TanA=1/2

TanA=0.5

Tan^-1 x (0.5)

<A= 26.565...

ROUND TO THE NEAREST DEGREE = 27 Degrees

Equation using the quadratic fromula for 0.05x^2 + 1.1x = 250

Anuta_ua [19.1K]

Answer:

x=60.56, x=-82.56

Step-by-step explanation:

Solve using quadratic formula

Formula is

$x=\frac{-b+-\sqrt{b^2-4ac}}{2a}$

0.05x^2 + 1.1x = 250

Subtract 250 on both sides

0.05x^2 + 1.1x - 250=0

a= 0.05, b=1.1 , c=-250

Plug in the values in the formula

$x=\frac{-1.1+-\sqrt{(1.1)^2-4(0.05)(-250)}}{2(0.05)}$

$x=\frac{-1.1+-7.156116265}{0.1}$

Now make two equations , one with + and one with -

then we solve for x

$x=\frac{-1.1+7.156116265}{0.1}$

x=60.56

$x=\frac{-1.1-7.156116265}{0.1}$

x=-82.56
