Which formula gives the x-coordinates of the maximum values for y = cos(x)?

Mathematics
1 answer:
REY [17]3 years ago
3 0

Answer with explanation:

The given trigonometric Function is,

     y= cos x

→The maximum value of , cos x , is 1,  at x=0 degree.

Cos x =1

→Cos x = Cos (0)degree,

x=2 k \pi \pm 0

→ for, k= An Integer

x=2 k π→→General formula that  gives the x-coordinates of the maximum values for y = cos(x)

Ordered Pair =(x,y)=(2 k π, 1)

For, any value of , k in the given equation, y will be always 1.

When is 20% off better than 20$ off
Crazy boy [7]

Answer:

Price > 100$

Price > 150$

Step-by-step explanation:

Let us assume that x% off of price y$  is better than x$ off.

Hence, \frac{xy}{1000} > x  

Hence, y > 100

Therefore, when the price is more than 100$, then only x% off on the price is better than x$. (Answer)

Again, assume that 20% off on price y$ is better than 30$ off.

Hence, \frac{20y}{100} > 30

⇒ y > 150$

Therefore, when the price is more than 150$, then only 20% of on the price is better than 30$ off. (Answer)

PLEASEEEEEEEE HELP
Rama09 [41]

Answer:

Using the point-slope form:

The equation of the line is given by:

y-y_1 =m(x-x_1) .....[1]  where

m is the slope of the line and (x_1, y_1) is the point on the line.

As per the statement:

Given: Two points i,e (34, 76) and (42, 91)

First calculate slope(m):

Slope is given by:

\text{Slope} = \frac{y_2-y_1}{x_2-x_1}

Substitute the given values we have;

\text{Slope (m)} = \frac{91-76}{42-34}=\frac{15}{8}=1.875

Now, substitute the value of m and (34, 76) in [1] we have;

y-76 =1.875(x-34)

Using distributive property: a \cdot (b+c) = a\cdot b+ a\cdot c

y-76 =1.875x-63.75

Add 76 to both sides we get;

y=1.875x+76

Therefore, the equation of the trend line is: y=1.875x+76
