Hello from MrBillDoesMath!

Answer: 2

Description. Create a line from point A perpendicular to the x axis. This line, with the radius (OA) , and x axis, form a right triangle. By Pythagoras,

x-length y-length hypotenuse squared

( 3 ^ (1/2) ) ^ 2 + 1 ^ 2 = 3 + 1 = 4

So, the square of the hypotenuse (or radius OA in this case) is 4. That means OA is the square root of 4 or 2.

Find the equation of a line perpendicular to x=6+6y that passes through the point (-8,6)

alexgriva [62]

Answer:

y = -6x - 42

Step-by-step explanation:

First solve for y in x = 6 + 6y.

6y + 6 = x

6y = x - 6

6/6y = x/6 - 6/6

y = 1/6x - 1 the slope is 1/6.

Perpendicular lines slopes are negative reciprocals of each other.

So the new equation will have the slope of -6 ( the negative reciprocal of 1/6)

Next solve for "b" by using y = mx + b and the new slope of -6 and the point (-8,6)

y = mx + b

6 = -6(-8) + b

6 = 48 + b

-42 = b

The equation of the line is y = -6x - 42

Find the small positive integer solution that solves the equation. if there is no solution, type NONE.

Degger [83]

Answer:

x = 7

Step-by-step explanation:

The equation can be rewritten to ...

8x = 13n +4 . . . . for some integers x and n

x = (13n +4)/8

For x to be an integer, 13n must be an odd multiple of 4. Since 13 is an odd number, n=4 will do.

x = (13·4 +4)/8 = 56/8

x = 7

The graph shows a "trial and error" method of solution. Only values of x less than 13 need to be examined.

A nursery has 10 tree seedlings to give out at 2 workshops. It wants to give out a minimum of 2 seedlings at each workshop. How

11111nata11111 [884]

We are given total 10 tree seedlings.

Number of workshops = 2.

Here order doesn't matters.

<em>When order doesn't matters we apply combination.</em>

We know formula of combination:

$C(n,r) = \frac{n!}{r!(n-r)!}$

For the given situation, we have

n=10 and r=2.

Plugging values in formula, we get

$\frac{10!}{2!(10-8)!} = \frac{10\times 9\times8!}{2!8!}$

$\frac{10 \times 9}{2} = \frac{90}{2} =45$

<h3>Therefore, 45 different ways can the nursery give out seedlings.</h3>
