which equation represent this relation
Answer:
hello,
answer A c=n+2
Step-by-step explanation:
if n=0 then c=2
if n=2 then c=4
slope=m=(4-2)/(2-0) =2/2=1
c-2=1*(n-0)
c=n+2
A saleslady is paid a commission of 3% on goods worth over 100,000 and a salary 11,000 .If she had a20% salary increase and total earnings of 22,200. Calculate the total amount received from sales
Answer:
I am not sure on the answer but i think its $9,000
Step-by-step explanation:
11,000x0.20=2,200
2,200+11,000=13,200
22,200-13,200=9,000
which would mean she got $9,000 from commissions.
if you did 100,000x0.03=3,000
9,000/3,000= 3
so she would have had 3 commissions worth over 100,000

which equation shows 2.4 as the constant of proportionality?
Answer:
c a = 2.4b
Step-by-step explanation:
y = kx is the form of the equation where k is the constant of proportionality
y and x can be any letters
Replacing y and x with a and b and k with 2.4
a = 2.4b
find k so that x^2+2x+k is a factor of 2x^4+x^3-14x^2+5x+6. also find all the zeroes of the two polynomial
Compute the quotient and remainder,
[tex]\dfrac{2x^4+x^3-14x^2+5x+6}{x^2+2x+k} \\\\ = 2x^2 - 3x - (8+2k) + \dfrac{(21+7k)x+(6+8k+2k^2)}{x^2+2x+k}[/tex]
The remainder upon dividing [tex]2x^4+x^3-14x^2+5x+6[/tex] by [tex]x^2+2x+k[/tex] should leave no remainder, which means
[tex]21+7k = 0 \implies 21 = -7k \implies k=-3[/tex]
and
[tex]6+8k+2k^2 = 0 \implies 2(k+3)(k+1)=0 \implies k=-3\text{ or }k=-1[/tex]
Only k = -3 makes both remainder terms vanish.
Then the previous result reduces to
[tex]\dfrac{2x^4+x^3-14x^2+5x+6}{x^2+2x-3} = 2x^2 - 3x - 2[/tex]
so that
[tex]2x^4+x^3-14x^2+5x+6 = (x^2+2x-3) (2x^2 - 3x - 2) \\\\ 2x^4+x^3-14x^2+5x+6 = (x+3)(x-1)(2x + 1)(x-2)[/tex]
and so the zeroes of the quartic polynomial are x = -3, x = 1, x = -1/2, and x = 2.

9514 1404 393
Answer:
b, c
Step-by-step explanation:
The factor (x+7) is common to both numerator and denominator. The function can be simplified by cancelling that factor.
y = (x -3)/(x -9) . . . . . . x ≠ -7
The restriction x ≠ -7 is put on the simplified function because the original function is undefined there. The denominator factor x+7 makes the denominator 0 at that point.
The point at x=-7 is called "hole" in the graph. A properly drawn graph will show the function is undefined there (has a hole).
__
The denominator of the simplified function is zero when x=9. This means there is a vertical asymptote at x=9.
__
The ratio of the highest-degree terms of the numerator and denominator will tell you the end behavior of the function — its value when x is large. Here, that ratio is y = x/x = 1. This represents a horizontal asymptote at y=1. The function approaches this line as x gets large, but never reaches it.
The appropriate descriptors are ...
Asymptote: x=9, y=1Hole: x=-7Find the coordinates of the missing endpoint if E is the midpoint of DF.
D(-3,-8), E(1,-2)
Answer:
F(5;4)
Step-by-step explanation:
Call F(x;y)
cuz E is the midpoint so we have a formula:
(-3+x)/2=1 -> x=5
(-8+y)/2=-2 -> y= 4
so F(5;4)
For the right triangle shown, use the trig functions to find the value of x. Round your answer to the nearest tenth
Answer:
28.3
Step-by-step explanation:
Use the Tangent
Tan(theta) = opposite over adjacent.
opposite (defined as the line that does not make up the angle) = 17
Theta = 31
adjacent (one of the lines making up the angle) = x
Tan(31) = 0.6009
Tan(31) = 17/x Multiply both sides by x
x*tan(31) = 17 Divide by tan 31
x = 17/tan31
x = 17 / 0.6009
x = 28.29
Rounded to the nearest 1/10 is 28.3

Determine the measure of the interior angle at vertex F
Answer:
72
Step-by-step explanation:
The interior angles of a 6 sided figure add to (n-2) * 180
where n is the number of sides
(6-2) *180
4*180
720
2x+4x+4x+4x+4x+2x = 720
20x = 720
Divide by 20
20x/20 = 720/20
x =36
We want <F
<F = 2x = 2*36 = 72

Answer:
Solution given:
Sin[tex]\theta_{1}=\frac{-24}{25}[/tex]
[tex]\frac{opposite}{hypotenuse}=\frac{-24}{25}[/tex]
equating corresponding value
opposite=-24
hypoyenuse=25
adjacent=x
By using Pythagoras law
hypotenuse²=opposite²+adjacent²
25²=(-24)²+x²
625=576+x²
x²=625-576
x=49
x=[tex]\sqrt{49}=7[/tex]
In IV quadrant
Cos angle is positive
Cos[tex]\theta_{1}=\frac{adjacent}{hypotenuse}[/tex]
Cos[tex]\theta_{1}=\frac{7}{25}[/tex]Answer:
cos theta = 7/25
Step-by-step explanation:
sin theta = opp / hyp
We can find the adj side by using the pythagorean theorem
adj ^2 + opp ^2 = hyp^2
adj^2 + (-24)^2 = 25^2
adj^2 +576 = 625
adj^2 =625 -576
adj^2 = 49
Taking the square root of each side
adj = 7
Since we are in the 4th quadrant, adj is positive
cos theta = adj / hyp
cos theta = 7/25

x^2 +12x +36=0
-------
Answer:
x = -6
Step-by-step explanation:
x^2 +12x +36=0
What 2 numbers multiply to 36 and add to 12
6*6 = 36
6+6 = 12
(x+6) (x+6) = 0
Using the zero product property
x+6 = 0 x+6 =0
x=-6 x=-6
Since they are the same we only list the solution once
Answer:
[tex]-6[/tex]
Step-by-step explanation;
[tex]x^{2} +12x+36=0[/tex]
Comparing with ax² +bx² + c=0
where a =1 , b=12, and c= 36
[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
substituting the values of a, b, and c to find the value of x
[tex]x=\frac{-12\pm \sqrt{12^2-4\cdot \:1\cdot \:36}}{2\cdot \:1}[/tex]
[tex]x=\frac{-12+,-\sqrt{144-144} }{2}[/tex]
[tex]x=\frac{-12+,-0}{2} =-6[/tex]
