Given cosine of x is equal to the square root of 3 over 2 comma what is the value of cos(x + π)?

The coordinates of each points are:

A = (-0.5, -5)

B = (0.8, -1.8)

C = (-2.6, -2.2)

D = (-1.5, -8.9)

E = (2.5, -6.5)

F = (-1.5, 3.1)

G = (-2.4, 4.1)

H = (1.5, 3)

I = (2.7, 1.5)

J = (-1.5, 0)

K = (-6.5, 0)

We have,

The coordinates of each point are in an ordered form.

i.e

(x, y)

x is the x-axis value.

y is the y-axis value.

Thus,

A = (-0.5, -5)

B = (0.8, -1.8)

C = (-2.6, -2.2)

D = (-1.5, -8.9)

E = (2.5, -6.5)

Answer:

Step-by-step explanation:

The two number of units need to be sold for the business to make a profit of $60 is A = 10 units

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

y = 0.3x² + 7x - 40

At profit of $ 60 , y = 60

60 = 0.3x² + 7x - 40

Subtracting 60 on both sides , we get

0.3x² + 7x - 100 = 0

Multiply by 10 , we get

3x² + 70x - 1000 = 0

And , roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

On simplifying , we get

x = [ -70 ± √ ( 70 )² - 4 ( 3 ) ( -1000 ) ] / 2 ( 3 )

x = [ -70 ± √ ( 4900 + 12000 ) ] / 6

x = ( -70 ± √16900 ) / 6

On simplifying the equation , we get

x = ( -70 ± 130 ) / 6

x = 10 or x = -100/3

The number of units cannot be negative , so x = 10 units

Hence , the values of x at the business has a profit of $ 60 is x = 10 units

Step-by-step explanation:

He bought a lunch two times, so $1.75*2 = 3.50.

To find arcsin, we need to use the identity:

sin(arcsin(x)) = x

Since arcsin is negative, sin(arcsin) is also negative. Therefore, we can say:

sin(arcsin) = -sqrt(1 - (cos)^2)

where (cos)^2 = 8/17

Substituting, we get:

sin(arcsin) = -sqrt(1 - (8/17))

Simplifying, we get:

sin(arcsin) = -sqrt(17/17 - 8/17)

Simplifying further, we get:

sin(arcsin) = -sqrt(9/17)

Therefore, arcsin = -sqrt(9/17)

To find arctan, we need to use the identity:

tan(arctan(x)) = x

Substituting, we get:

tan(arctan) = -8/17

Therefore, arctan = -8/17

So, arcsin is -sqrt(9/17) and arctan is -8/17.

Answer:

f(0) = 2     f(5) = 147

Step-by-step explanation:

f(0) = (0²+10·0+72)/(0²-12·0 + 36)   Substitute 0 for x and solve.

      = 72/36

       = 2

f(5) = (5²+10·5+72)/(5²-12·5 + 36)      Substitute 5 for x and solve.

     = (25 + 50 + 72)/(25 - 60 +36)

     = 147/1

      = 147

Based on the information we can infer that the equation shown in the image is 1.23 - 0.35 = 0.88 (option B).

To identify the correct equation we must look at the graph and identify the information it provides. In this case we have two squares divided into 100 squares each. Additionally, the square on the left has 88 squares painted in red and 12 squares with an X inside. In the case of the square on the right, it has 23 squares colored in red with an X inside.

In total we have 123 squares painted in red, which in decimal number is equivalent to 1.23. On the other hand, the number of squares painted red and with an X inside is 35, this value would be 0.35.

On the other hand, the squares painted only in red are 88, so the equivalent in decimal numbers would be 0.88. Therefore, the correct way to express this relationship through an equation would be:

Answer: Do you have a pic of the question if you do give and  give brainliest for it alright

Step-by-step explanation:

If you're asking about the difference quotient alone, you have

f (x) = x ² - 2x

which means

f (x + h) = (x + h)² - 2 (x + h)

so that

(f (x + h) - f (x)) / h = (((x + h)² - 2 (x + h)) - (x ² - 2x)) / h

… = (x ² + 2xh + h ² - 2x - 2h - x ² + 2x) / h

… = (2xh + h ² - 2h) / h

*and you would stop here*.

On the other hand, if you're talking about the derivative (which I believe you are, since your question says f '), take the limit as h approaches 0. In particular, this means h ≠ 0, so there is some cancellation:

(f (x + h) - f (x)) / h = (2xh + h ² - 2h) / h

… = 2x + h - 2

Then as h approaches 0, you're left with

f ' (x) = 2x - 2

Danny has 10 + x baseball cards

The equation of the ellipse with foci at (0 ±10) and vertices at (0 ±11) is \(\frac{x^2}{21} + \frac{y^2}{100} = 1\)

We have:

Vertices = (0, ± 11),

Foci = (0, ± 10)

The vertices and the foci are represented as:

Foci = (0, ± a)

Vertices = (0, ± c)

So, we have:

a = 10

c = 11

The equation of b is calculated using:

b² = c²- a²

So, we have:

b² = 11²- 10²

Evaluate

b² = 21

The equation of the ellipse is then represented as:

\(\frac{x^2}{b^2} + \frac{y^2}{a^2} = 1\)

This gives

\(\frac{x^2}{21} + \frac{y^2}{10^2} = 1\)

\(\frac{x^2}{21} + \frac{y^2}{100} = 1\)

Hence, the equation of the ellipse is \(\frac{x^2}{21} + \frac{y^2}{100} = 1\)

2. Again, graph the points on a coordinate plane and you can count each grid box until you count 3 boxes right on the axis and 1 grid= 1 mile 3 grids= 3 miles

2 on division by 3/7 yields 14/3.

For the division of two fractions, we need to multiply the first fraction with the reciprocal of the second. Reciprocal of a fraction means interchanging the numerator and denominator ie, the reciprocal of a is 1/a, the reciprocal of p/q = q/p, and so on.

For example, if a/b and c/d are the fractions the a/b ÷ c/d = a/b x d/c =ad/bc.

Implementing the same method to solve this question,

We have 2/1 = 2 as the first and 3/7 as the second fraction. Thus,

2 ÷3/7 =2 x 7/3 = 14/3. So 14/3 is the answer.

The value of x in the triangle is determined as 45.

The value of x in the triangle is calculated by applying the following formula,.

The measure of angle ABD = 0.2x + 52

The measure of angle CBD = 0.2x + 42

From the diagram, we can set-up the following equations;

x + 16 = 0.2x + 52

Simplify the equation above, by collecting similar terms;

x - 0.2x = 52 - 16

0.8x = 36

Divide both sides of the equation by " 0.8 "

0.8x / 0.8 = 36/0.8

x = 45

Thus, the value of x in the triangle is calculated by equating the appropriate values to each other.

Step-by-step explanation:

As shown in the picture below, the x side of the table has the same rate of change of +1. However, due to the fact that the y side does not have the same rate of change, +6 and +3, the table represents a non linear function. If the rate on the y side of the table were all the same, then this would be a Linear function.
