Find the point-slope equation for

Mathematics
1 answer:
iris [78.8K]3 years ago
4 0

Answer: y+9=-2(x-9)

Step-by-step explanation:

The point-slope equation is y-y_{1} =m(x-x_{1} ). All we have to do is fill in all the values except for y and x.

To find m, you use \frac{y_{2}-y_{1}  }{x_{2} -x_{1} }. Since we are given 2 points, we cna plug them in.

\frac{13-(-9)}{-2-9} =\frac{22}{-11} =-2. Now that we have our slope m, we can fill in the point slope equation.

y-(-9)=-2(x-9)

y+9=-2(x-9)

Help Me Pls Thanks <3
dybincka [34]
If there are 150 total instruments in said Orchestra, we'll need to divide that number in half.
75, simple enough. Now we know that half of 150 is 75.
Start by writing your problem like this: 150= 75w+37.5b
That equation is all I can think of, because 37.5 is half of 75, which means that's roughly the number you're looking for. Sorry if this doesn't help much<span />

Simplify the square root of 27x^12/300x^8
Darina [25.2K]
The first thing we are going to do is rewrite the expression correctly.
 We have:
 root (27x ^ 12 / 300x ^ 8)
 Rewriting:
 root ((27/300) * (x ^ 12 / x ^ 8))
 root ((9/100) * (x ^ (12-8)))
 root ((9/100) * (x ^ (4)))
 root ((9/100) * (x ^ (4)))
 3 * x ^ 2 * root ((1/100)
 (3 * x ^ 2) / 10
 (3/10) * (x ^ 2)
 Answer:
 (3/10) * (x ^ 2)

The volume of a cylinder, V, in terms of radius, r,
Igoryamba

Answer:

See explanation

Step-by-step explanation:

Volume of a cylinder = πr²h

Solve for r

V = π * r² * h

r² = V/πh

Find the square root of both sides

r = √V/πh

If height = 6 meters and volume = 300 cubic meters. Find r

r = √V/πh

= √(300/3.14*6)

= √(300/18.84)

= √15.923566878980

r = 3.9904344223381

Approximately,

r = 4 meters
