Which function has a range limited to only negative numbers?

Answer:

x = 112°

Step-by-step explanation:

This figure shown is a pentagon. The total sum of degrees in a pentagon equals to 540° according to the formula (n - 2)180° where n is the number of sides. (5 - 2)180° = 3 × 180° = 540°.

To find x, we need to subtract all the given angles from 540°.

x = 540° - 130° - 118° - 105° - 75° = 112°

Answer:

x = 112°

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 , then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540°

105° + 118° + 75° + 130° = 540°

428° + x = 540° ( subtract 428° from both sides )

x = 112°

Answer:

Radiation is the emission and propagation of energy in the form of waves, rays or particles

Step-by-step explanation:

Since the two equations are of line and coincident to each other so the equations will have an infinite number of solutions.

The equation which have a degree of one will be called as the linear equation the graph of the equation will be always a straight line.

Here we have the equation:

x-5=-5+x

or

x-5=x-5

Here we can see that the ratios are same:

[tex]\dfrac{a_1}{b_1}=\dfrac{a_2}{b_2}\\\\\\\\\dfrac{1}{-5}=\dfrac{1}{-5}[/tex]

So the equations will be coincident to each other or line one will coincide with line 2. Hence the two equations are of line and coincident to each other so the equations will have an infinite number of solutions.

Answer:

60.

Step-by-step explanation:

The second digit is 6, so we round up the first digit and add training zero. There is no need to add the '00' after the decimal point.

The operation that should be completed first to find the value of the expression is 6 - 3

The equation is given as:

12 + 30 = (6 - 3) +1

By the rule of BODMAS, the first expression that should be evaluated is the expression in the bracket

This means that we solve for 6 - 3, first.

Hence, the operation that should be completed first to find the value of the expression is 6 - 3

The rectangle maximum area will be A=9 square units with the length=3 and the width=3.

Area is defined as the space occupied by a plane or rectangle having length and width in two dimensional plane.

It is given that the perimeter of rectangle is P=12

So from the formula of perimeter of rectangle

2(L+W)=12

L+W=6

L=6-W

Now the area of rectangle will be

A=LxW

A=(6-W)W

Now for maximum area we will find the derivative and equate to zero.

[tex]A=(6W-W^2})[/tex]

[tex]A'=6-2W=0[/tex]

[tex]W=3[/tex]

[tex]L=6-W=6-3=3[/tex]

So the area will be

The probability that all of the buttons are black when four buttons are picked at random from a which jar contains four black buttons and three, is 1/35.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

A jar contains four black buttons and three brown buttons. The total number of buttons is,

[tex]4+3=7[/tex]

The probability of picking a black button in the first attempt is,

[tex]P_1=\dfrac{4}{7}[/tex]

Now, there is total 6 buttons remain in which 3 are black buttons. Thus, the probability of picking black button in second attempt is,

[tex]P_2=\dfrac{3}{6}[/tex]

Similarly, for the third event,

[tex]P_3=\dfrac{2}{5}[/tex]

For the fourth event,

[tex]P_4=\dfrac{1}{4}[/tex]

The probability that all of them are black by the chain rule of probability,

[tex]P=\dfrac{4}{7}\times\dfrac{3}{6}\times\dfrac{2}{5}\times\dfrac{1}{4}\\P=\dfrac{1}{35}[/tex]

Thus, the probability that all of the buttons are black when four buttons are picked at random from a which jar contains four black buttons and three, is 1/35.

D. 36.75-3x

Step-by-step explanation:

You have a total amount of 36.75.

Since you are spending money you need to subtract.

We know that Marshall buys 3 tickets.

We also know that 'x represents the amount of a single ticket.

Remember that they are asking you for an algebraic expression and not an equation.

So you need to take away from your total, 36.75. And since you plan on buying three tickets and aren't given the amount x it leaves you with taking 3x from your total 36.75 or an other words

D. 36.75 - 3x

The measure of angle x, the angle of elevation, is rounded to the nearest degree.

[tex]tan(\theta)=\frac{Opposite \ side}{Hypotenuse}[/tex]

From the diagram,

Opposite side=20ft

Adjacent side=36ft

Use this value of the above formula.

So we get,

[tex]tan(\theta)=\frac{20}{36} \\\\tan(x)=5/9\\\\tan(x)=0.55\\x=tan^{-1}(0.55)\\x=31.51^0[/tex]
