Choose two consecutive points on the graph and find the rate of change. Is the slope the same or different?

The least positive number x for which cos x = 0 is 1.

The given trigonometric equation is cos x=0.

A trigonometric equation is one that involves one or more of the six functions sine, cosine, tangent, cotangent, secant, and cosecant. Some trigonometric equations, like x = cos x, can be solved only numerically, through successive approximations.

Now, cos x = 0

So, [tex]x=cos^{-1}(0)[/tex]

⇒ x = 1

Therefore, the least positive number x for which cos x = 0 is 1.

The given inequalities are :

2x + 8 > 18

2c + 8 < 18

Inequality 1 : 2x + 8 > 18

Simplify

Subtract 8 from both side :

2x + 8 - 8> 18 - 8

2x > 10

Divide both side by 2

x > 5

Inequality : 2c + 8 < 18

2c + 8 < 18

Subtract 8 from both side:

2c + 8 - 8 < 18 - 8

2c < 10

Divide both side by 2:

2c/2 < 10/2

c < 5

So, the solution is x > 5 and c < 5

So, equation will be : c < x < 5

The smaller number = 27

The larger number = 119

Let the smaller number be x

Let the larger number be y

The sum of the two numbers is 146

x + y = 146..............(1)

The larger number is 16 less than five times the smaller number

y = 5x - 16.............(2)

Substitute equation (2) into equation (1)

x + (5x - 16) = 146

x + 5x - 16 = 146

6x = 146 + 16

6x = 162

x = 162/6

x = 27

Substitute the value of x into equation (2)

y = 5(27) - 16

y = 135 - 16

y = 119

The smaller number = 27

The larger number = 119

Answer:

a. If the selection is made with replacement, they are NOT independent because they affect each other.

b. The probability of selecting TWO accurate orders is .7157 and the events ARE independent.

Step-by-step explanation:

Add the accurate orders:

315+273+248+125=961

Add the inaccurate orders:

38+56+37+17=148

148/961=0.1540 probability of getting ONE inaccurate order

1.0-0.1540=0.846 probability of selecting ONE accurate order

0.846 * 0.846 = 0.7157 the probability of selecting TWO accurate orders

Therefore, the probability is .7157 and the events ARE independent.

Answer:

y = [tex]\frac{5}{4}[/tex] x - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = [tex]\frac{5}{4}[/tex] , then

y = [tex]\frac{5}{4}[/tex] x + c ← is the partial equation

to find c substitute (- 4, - 6 ) into the partial equation

- 6 = - 5 + c ⇒ c = - 6 + 5 = - 1

y = [tex]\frac{5}{4}[/tex] x - 1 ← equation of line

We are asked to select the mathematical expressions that represent 40% of 84

We then recall that the mathematical form of 40% is in fact 40 / 100 = 0.4

Then, 40% of 84 can be written in math terms as:

40/100 times 84 = 40/100 * 84

or also

0.4 times 84 = 0.4 * 84

g(x) + 4 = x

g(x) = x - 4 which is probably the answer you should submit.

Step-by-step explanation:

Givens

f(x) = x

g(x) +4 = f(x)  

Comment

f(x) and g(x) are forms of y or z. What they mean is that whatever x is on the left, it will be make the same on the right. It is just a short hand to help you in defining the y value.

If you want to move down, The y value is the one to notice. Notice that it is not intuitive. If you want to go down the sign on y + 4 = x is the equation you use. It is the exact opposite of what you think it should be. The graph below should help you.

The red line is f(x)  = x

The blue line is g(x) + 4 = x.

The blue line can be written as g(x) = x - 4 which would be more inetuitive.

Given

Tax rate = 28.5 mills

Smith's house is accessed at $80,000

Jones's house is accessed at $67,000

Property taxes are calculated by multiplying the assessed, taxable property value by the mill rate and then dividing that sum by 1,000.

The formula is given by:

Property tax for the Smith's:

Property tax for the Jones':

The extra amount the Smith's pay is the difference in the tax levied on Smith and Jones:

Hence, the Smith's pay $370.5 more than the Jones'

(a) 250000 of this revenue was sales and $11250 much was sales tax. (b) $11250 of sales tax should be sent to the city and $3750 sales tax should be sent to the state.

Let us assume that the total sales are $X.

According to the given situation, 7% is the sales tax and an additional state sales tax of 1.5% will be charges on the sales.

The total revenue including sales tax is $271250.

(a) Total revenue = sales + total sales tax

So, we can write,

X + X(7+1.5)% = 271250

Solving further,

X + X(8.5%) = 271250

X + 8.5X/100 = 271250

108.5X = 271250×100

X = 250000

Total sales is $250000.

Total sales tax is $(2710250-250000)

Total sales tax is $21250.

(b) Total sales is $250000.

Tax charges by city is 7%.

Using percentage formula,

Percentage of tax = Total tax amount/Total sales amount × 100

Putting all the values,

7 = Total tax amount/250000 × 100

Total tax amount = 7 × 2500

Total tax amount = 17500 dollars.

Total amount to be sent to the city is 175000$.

(c) Total sales is $250000.

Tax charges by city is 1.5%.

Using percentage formula,

Percentage of tax = Total tax amount/Total sales amount × 100

Putting all the values,

1.5 = Total tax amount/250000 × 100

Total tax amount = 1.5 × 2500

Total tax amount = 3750 dollars.

Total amount to be sent to the city is 175000$.

a. The company will break even in 6 years

b. The total profit with the newly developed line of business is:

c. The company will break even 3 years sooner

The projected profit is given as:

a. The company will break even when the profit is zero. That is;

6 is the realistic number of years (As we cannot have -3/2 years).

We conclude that they will break even in 6 years

b. The projected profit of a newly developed line of business is:

The total profit is now;

The company will break even with this new line of business as follows:

We choose t = 3 (because we cannot have -2 years or -3 years)

The difference between this and the previous time is 6 - 3 = 3 years

The company will break even 3 years sooner

The second expression 1/(x^2 - 4x + 3) is equivalent to the given expression.

What are the equivalent expression?

Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).

Consider the given expression,

((x + 3) / (x^2 - 2x - 3)) / ((x^2 + 2x -3)/ (x + 1))

We can write the expression as,

((x + 3) / (x^2 - 2x - 3)) x ((x + 1) / (x^2 + 2x -3))        

Rewrite the equation x^2 - 2x - 3 and x^2 + 2x -3 as,

x^2 - 2x - 3 = x^2 - 3x + x - 3 = (x - 3)(x + 1)

x^2 + 2x - 3 = x^2 + 3x - x - 3 = (x + 3)(x - 1)

plug these values in the above expression, we get

((x + 3) / ((x - 3)(x + 1)) x ((x + 1) / ((x + 3)(x - 1))

After solving this, we get

1 / ((x - 3)(x - 1) = 1 / (x^2 - 4x + 3)

Therefore, the second expression is equivalent to the given expression.

The amount of flour needed for 72 cookies is 4.5 cups.

46 / 69 and 48/84 are not proportional because the fractions in their simplest forms are 3/4 and 4/7.

The value of x in  2/3 = 1.2 / x is 1.8.

The value of x in 8 / 15 = 24 / x is 45.

7 / 5 ≠ 15 / 10.

6 / 8 = 15/20

In order to determine how many cups of flour is needed for 72  cookies, determine how many cups is needed for one cookies.

Amount of flour needed for one cookie = 3/48

Now, multiply this fraction by 72: 3/48 x 72 = 4.5 cups

If two fractions are proportional, when they are expressed in their simplest form, both fractions would have equal values.

46 / 69 = 2 / 3

48 / 84 = 4/7

Given this equation : 2/3 = 1.2 / x

In order to determine the value of x, cross multiply:

2x = 3 x 1.2

2x = 3.6

x = 3.6 / 2

x = 1.8

Given this equation : 8 / 15 = 24 / x

In order to determine the value of x, cross multiply:

8x = 24 x 15

8x = 360

x = 360 / 8

x = 45

7/5 and 15 / 10

7/5 =  15 /10

The cross product:

(7 x 10) = (5 x 15)

70 ≠ 75

6 / 8 = 15/20

The cross product : (6 x 20) = (8 x 15)

A function is a relation that gives one input for every one output thus the value of g(10) is -31.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given function,

g(x) = -3x - 1

The value of the function at x = 10

g(10) = -3(10) - 1

g(10) = -30 - 1 = -31
