34 per feet because if you count to 16 it will be 34
Answer:
n=11.5
Step-by-step explanation:
n+6/-4=10
<em>6 divided by -4=-1.5</em>
n-1.5=10
<em>add 1.5 to both sides</em>
n=11.5

Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Step-by-step explanation:
Part 1) what is the value of side XY?
we know that
In the right triangle XYZ
Applying the Pythagoras Theorem
substitute the values
Part 2) what is the value of sin(x)?
we know that
In the right triangle XYZ
------> the sine is equal to divide the opposite side angle (x) by the hypotenuse
substitute the values
Part 3) what is the value of cos(x)?
we know that
In the right triangle XYZ
------> the cosine is equal to divide the adjacent side angle (x) by the hypotenuse
substitute the values
Part 4) what is the value of tan(x)?
we know that
In the right triangle XYZ
------> the tangent is equal to divide the opposite side angle x by the adjacent side angle (x)
substitute the values
<span>3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = 0
3x^2 is factorable only as 3x and x.
15 can be 15 * 1 or 3 * 5.
As a first guess, I place 5 and 3 in that order.
The coefficients of y are unknown so far.
= (3x + Ay + 5)(x + By + 3)
= 3x^2 + 3Bxy + 9x + Axy + ABy^2 + 3Ay + 5x + 5By + 15
(3B + A)xy = 10xy
(3A + 5B)y = 22y
A + 3B = 10
3A + 5B = 22
-3A - 9B = -30
3A + 5B = 22
4B = 8
B = 2
A + 3B = 10
A + 6 = 10
A = 4
</span>
3x^2 + 10xy + 8y^2 + 14x + 22y + 15 = <span>(3x + 4y + 5)(x + 2y + 3)
The product of </span><span>(3x + 4y + 5)(x + 2y + 3) is indeed
</span><span>3x^2 + 10xy + 8y^2 + 14x + 22y + 15
The lines are
</span><span>3x + 4y + 5 = 0
x + 2y + 3 = 0</span>
Answer:
b -1
Step-by-step explanation:
it's the line that the curve ends on and is linear on
