which function has the range (-infinity,-2]U[0,infinity)?

a. y=cos(x+1)
b. y=csc(x)-1
c. y=sec(x)+1
d. y=cot(2x)-1

Answer:

0.68268

Step-by-step explanation:

We solve using z score

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

For x = 85

z = 85 - 105/20

z = -1

Probability value from Z-Table:

P(x = 85) = 0.15866

For x = 125

z = 125 - 105/20

z = 1

Probabilty value from Z-Table:

P(x = 125) = 0.84134

The probability that a randomly selected adult has an IQ between 85 and 125 is calculated as:

P(x = 125) - P(x = 85)

= 0.84134 - 0.15866

= 0.68268

Answer:   -1.4

The opposite of -1.4 is 1.4; you flip from negative to positive.

Then taking the opposite of 1.4 gets us back to -1.4 again

Effectively the two opposites cancel out and nothing changes.

Answer:

-1.4

Step-by-step explanation:

because if it says the opposite then

it goes like this

opposite one time = positive 1.4

then do the opposite of a positive = -1.4

Answer:

Approximately 107 when rounded to the nearest whole number

see below for more accurate answer

Step-by-step explanation:

First, we pull out our formula.

C is circumference, D is diameter.

[tex]C=2\pi r\\D=2r\\C=\pi D[/tex]

We now insert 34 for D.

[tex]C=34\pi \\[/tex]

Pi is 3.141592653589..., so our answer is approximately 106.814150222. You can round this to your desire.

Answer:

25 black keys

Step-by-step explanation:

Let the number of requires black keys = 'x'

White key : Black keys = 7 : 5

7 : 5  :: 35 : x

Product of extremes = product of means

             7 *x = 35 * 5

                  x = [tex]\frac{35*5}{7}[/tex]

                 x = 5 *5

                 x = 25

Answer:

1.76

Step-by-step explanation:

0.79 + 0.97

The number 1.76 is 0.79 more than 0.97.

A number is a basic unit of mathematics. Numbers are used for counting, measuring, and comparing amounts. A number system is a set of symbols, or numerals, that are used to represent numbers.

Given what number is 0.79 more than 0.97,

Let the number be x,

x = 0.79 + 0.97

x = 1.76

Hence, the number 1.76 is 0.79 more than 0.97.

Answer:

x-intercept = 3

y-intercept = - 6

Step-by-step explanation:

The intersection of the line with the x-axis is known as the x-intercept and it's calculated by making y = 0.

Also, the intersection of the line with the y-axis is known as the y-intercept and it's calculated by making x = 0.  

Given the following data;

Equation of straight line is [tex]y = 2x - 6[/tex]

To find the intersection;

When y = 0, the equation crosses the x-axis.

y = 0;

Substituting into the equation, we have;

0 = 2x - 6

2x = 6

x = 6/2 = 3

x = 3

(x, y) = (3, 0) on the x-axis.

When x = 0, the equation crosses the y-axis.

x = 0;

Substituting into the equation, we have;

y = 2(0) - 6

y = 0 - 6

y = -6.

(x, y) = (0, -6) on the y-axis.

Therefore, the coordinates of the intersection of the graph is (3, 0) and (0, -6).

Answer:

First you need to get your variable(x) by itself.

You do that by adding 16 to both sides of the greater than sign.

The 16 cancels or goes away. and 16 + 4 =20.

Your new equation is 20<4x

Finally you divide 20 by 4 to get 5

Your answer is 5<x or x>5.

Answer:

9/10

Step-by-step explanation:

Answer:

Option (D)

Step-by-step explanation:

Area of a rectangle = Length × width

Area of large rectangle = (3x - 1)(3x + 7) square units

                                       = (9x² + 21x - 3x - 7)

                                       = 9x² + 18x - 7

Area of small rectangle = (2x + 5)x

                                       = (2x² + 5x) square units

Area of the shaded region = Area of large rectangle - Area of small rectangle

= (9x²+ 18x - 7) - (2x² + 5x)

= (9x² - 2x²) + (18x - 5x) - 7

= (7x² + 13x - 7) square units

Therefore, Option (D) will be the correct option.

The expression that represents the area of the shaded region is:[tex]7x\² + 13x - 7[/tex]

The dimension of the big rectangle is given as:

So, the area of the rectangle is:

[tex]Area = Length \times Width[/tex]

[tex]Area= (3x - 1) \times (3x + 7)[/tex]

Expand

[tex]Area = 9x\² + 21x - 3x - 7[/tex]

[tex]Area = 9x\² + 18x - 7[/tex]

The dimension of the small rectangle is given as:

So, the area of the rectangle is:

[tex]Area = Length \times Width[/tex]

[tex]Area= (2x + 5) \times x[/tex]

Expand

[tex]Area = 2x\² + 5[/tex]

The area of the shaded region is the difference between the area of the big and small rectangles.

So, we have:

[tex]Area = (9x\²+ 18x - 7) - (2x\² + 5x)[/tex]

Expand, and collect like terms

[tex]Area = 9x\²- 2x\² + 18x -5x- 7[/tex]

[tex]Area = 7x\² + 13x - 7[/tex]

Hence, the area of the shaded region is [tex]7x\² + 13x - 7[/tex]
