Ok, so it seems
erm
ok, even and odd
it is an odd one because the power is odd (3rd degree)
so then the ends go in different directions
and since leading coefient (5 in the 5x^3) is positive, it goes from bottom left to top right
so
A is false
B is false
C and D are true
answer is C and D
Answer:
Neither
Step-by-step explanation:
When you rearrange the equation 3x+2y=1 in the form of y=mx+c
you get:
2y=-3x+1
And if you compare it with the equation y= -x -1
You can see that the gradient is not the same, so it means it is not parallel.
To get if it is perpendicular you need to see if the two gradients multiply to give the value -1 but when you multiply
× so it is not perpendicular as well
I hope it is right, feel free to point out anything wrong or you're unsure of :)
6.31 is a rational number.
Answer:
D.
Step-by-step explanation:
All the y values for f(x) are less than -1 and go upto infinity.
Given:
Right triangles:
To find:
The value of c and value of d
Solution:
<u>In the first right triangle:</u>
θ = 45°
Opposite side to θ = 5
Hypotenuse = c
The value of sin 45° =
Do cross multiplication, we get
<u>In the second right triangle:</u>
θ = 60°
Opposite side to θ = 4
Adjacent side to θ = d
Do cross multiplication, we get
The value of and .
