4/3 vs 6/3
4 parts out of 3 or 6 parts out of 3
they are both out of 3
4<6
4 is bigger than 6
therefor martin buys more

What is the slope and vertical intercept of y = 6x-2?

Bogdan [553]

Even function : A function is even if f(-x) = f(x) for all x∈ R

Odd function : A function is odd if f(-x) = -f(x) for all x ∈ R

Check if 6 x -2 is even : false
Check if 6x -2 is odd : false

f(-x) ≠ f(x) and f(-x) ≠ - f(x) therefore 6x -2 is neither even nor odd

Axis interception points of 6x - 2 :

x intercepts : $(\frac{1}{3} ,0)$

y intercepts : $(0,-2)$

inverse of 6 x - 2 : $\frac{x+2}{6}$

Graph:

plotting : y = 6 x - 2

Find the exact value of cos(a+b) if cos a=-1/3 and cos b=-1/4 if the terminal side if a lies in quadrant 3 and the terminal side

maria [59]

Answer:

cos(a + b) = $\frac{1}{12}(1-2\sqrt{30})$

Step-by-step explanation:

cos(a + b) = cos(a).cos(b) - sin(a).sin(b) [Identity]

cos(a) = $-\frac{1}{3}$

cos(b) = $-\frac{1}{4}$

Since, terminal side of angle 'a' lies in quadrant 3, sine of angle 'a' will be negative.

sin(a) = $-\sqrt{1-(-\frac{1}{3})^2}$ [Since, sin(a) = $\sqrt{(1-\text{cos}^2a)}$ ]

= $-\sqrt{\frac{8}{9}}$

= $-\frac{2\sqrt{2}}{3}$

Similarly, terminal side of angle 'b' lies in quadrant 2, sine of angle 'b' will be negative.

sin(b) = $-\sqrt{1-(-\frac{1}{4})^2}$

= $-\sqrt{\frac{15}{16}}$

= $-\frac{\sqrt{15}}{4}$

By substituting these values in the identity,

cos(a + b) = $(-\frac{1}{3})(-\frac{1}{4})-(-\frac{2\sqrt{2}}{3})(-\frac{\sqrt{15}}{4})$

= $\frac{1}{12}-\frac{\sqrt{120}}{12}$

= $\frac{1}{12}(1-\sqrt{120})$

= $\frac{1}{12}(1-2\sqrt{30})$

Therefore, cos(a + b) = $\frac{1}{12}(1-2\sqrt{30})$

Please help out it for my math homework and I sure do have more questions

GalinKa [24]

Answer:

30°

Step-by-step explanation:

Remember, all the interior angles of a triangle add up to 180 degrees. Therefore, we can find the value of x by subtracting the values of the other angles from 180:

$x = 180-97-53$
