Answer:

$84

Step-by-step explanation:

This is a super simple question. All you have to know is how much money will be charged a month, and how many months there are in a year. Just simply multiply 7 by 12 as the streaming service is charging 7 dollars a month and there are 12 months in a year. After you multiply the two numbers, you should end up with 84 dollars charged after 1 year.

Answer:

  97 ft

Step-by-step explanation:

The Pythagorean theorem is useful for working problems like this. It tells you the relationship between side lengths and the hypotenuse of a right triangle.

Here, the building is presumed to be perpendicular to the ground, so the 100' rope is the hypotenuse of a triangle with legs equal to 23' and the height of the building (b).

  23² +b² = 100²

  b = √(10000 -529) ≈ 97.32

The height of the building is about 97 feet.

Answer:

12

Step-by-step explanation:

The number of cookies that are left unsold if they work from 6:00 AM until noon is 12.

Cookies baked per hour by Christine = 20*2 =40

Cookies sold per hour by Charlie = 38

There will be 6 hours between 6:00 AM and noon.

So, Cookies baked by Christine in 6 hours = 40*6 =240

Cookies sold by Charlie in 6 hours = 38*6 =228

Number of unsold cookies =240-228 =12

Hence, the number of cookies that are left unsold if they work from 6:00 AM until noon is 12.

Used a calculator to find all the square roots, .06's is 0.24, which is the closest out of all of the options to the graph.

Answer:

television/ video games= 1/4

Step-by-step explanation:

cuz there are 2 sets of 30 min in an hour, make the video games time 4 sets of 30 min, and the tv time 1 set. so , the ratio would be 1/4.

The ratio of the amount of time spent on watching television to the amount of time spent on playing video games as a fraction in the simplest form is 1 : 4.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Time spend on watching television = 30 minutes.

And time spend on playing video games = 2 hours.

To find the ratio of the amount of time spent on watching television to the amount of time spent on playing video games,

Use ration property,

Ratio = time spend on watching television/ time spend on playing video games

         = 30 minutes / 2 hours

         = 30 minutes / 2 x 60 minutes

         = 1 / 4

Ratio = 1 : 4

The required ratio of time spend on television to time spend on playing video games is 1 : 4.

1 and 28 are not equivalent.

Another example would be x = 6

Step-by-step explanation:

Answer:

Z = - 2, Y = 0, X = 0

Step-by-step explanation:

2X – Y + Z = – 2

6X + 3Y – 4Z = 8

– 3X + 2Y +3Z = – 6

isolate "X" in the first equation

2X - Y + Z = - 2 => isolate "2X"

2X = - 2 - Z + Y => divide either side by 2

X = - 1 - Z/2 + Y/2

substitute this value of X in the second two equations (applying the substitution method here)

6(- 1 - Z/2 + Y/2) + 3Y - 4Z = 8,

6Y - 7Z - 6 = 8

- 3(- 1 - Z/2 + Y/2) + 2Y +3Z = - 6,

Y + 9Z + 6/2 = - 6

isolate Y in the second equation (6Y - 7Z - 6 = 8) and substitute in the third equation (Y + 9Z + 6/2 = - 6)

6Y - 7Z - 6 = 8 => isolate 6Y

6Y = 14 + 7Z => divide either side by 6

Y = 7Z + 14/6 => substitute in second equation

7Z + 14/6 + 9Z + 6/2 = - 6 => solve for Z

61Z + 50/12 = - 6, Z = - 2

substitute the value of Z into the equations "Y = 7Z + 14/6" and using the value of Y and Z, substitute into "X = - 1 - Z/2 + Y/2"

Y = (7(- 2) + 14)/6 = 0 / 6

= 0

X = - 1 - (- 2)/2 + 0/2 = - 1 - (-1) + 0

= - 1 + 1 + 0 = 0

The equation of the line is 7x+2y = 1

The equation of a line is linear in the variables x and y which represents the relation between the coordinates of every point (x, y) on the line. i.e., the equation of line is satisfied by all points on it.

Given that a line is passing through two points J(-3, 11) and K(1, -3). we need to find the equation of line JK,

So, we know that the equation of a line passing from two points (x₁, y₁) and (x₂, y₂) is =

y-y₁ = y₂-y₁/x₂-x₁ (x-x₁)

Here, (x₁, y₁) and (x₂, y₂) = J(-3, 11) and K(1, -3)

Therefore, the equation of the line =

y-11 = -3-11 / 1+3 (x+3)

y-11 = -7/2(x+3)

Multiply by 2,

2y-22 = -7(x+3)

2y-22 = -7x-21

7x+2y = 1

Hence the equation of the line is 7x+2y = 1

Answer:

The correct option is;

y = arcsinx and y = arctanx

Step-by-step explanation:

The given options are;

1) y = arcsinx and y = arccosx

Here, we have at the origin, where x = 0,  arccosx ≈ 1.57 while arcsinx = 0

Therefore arccosx does not intersect arcsinx at the origin for it to be symmetrical to arcsinx or the origin

2)  y = arccosxy and y = arctanx

Here arctanx = 0 when x = 0 and arcos x = 1.57 when x = 0 therefore, they are not symmetrical

3) y = arctanx and y = arccotx

Similarly, At x = 0, arccotx = 1.57 therefore, they are not symmetrical

4) y = arcsinx and y = arctanx

Both functions arcsinx and arctanx pass through the origin and their shapes are similar but inverted as they go from negative to positive.

The function are symmetric with respect to the origin is y = arcsinx and y = arctanx and this can be determined by using the trigonometric property.

The following steps can be used in order to determine which functions are symmetric with respect to the origin:

Step 1 - Check all the options given in order to determine which functions are symmetric with respect to the origin.

Step 2 - Substitute (x = 0) in option a), that is:

[tex]\rm y = sin^{-1}(0)=0[/tex]

[tex]\rm y = cos^{-1}(0)=1.57[/tex]

Step 3 - Substitute (x = 0) in option b), that is:

[tex]\rm y = cos^{-1}(0)=1.57[/tex]

[tex]\rm y = tan^{-1}(0)=0[/tex]

Step 4 - Substitute (x = 0) in option c), that is:

[tex]\rm y = tan^{-1}(0)=0[/tex]

[tex]\rm y = cot^{-1}(0)=1.57[/tex]

Step 5 - Substitute (x = 0) in option d), that is:

[tex]\rm y = tan^{-1}(0)=0[/tex]

[tex]\rm y = sin^{-1}(0)=0[/tex]
