The  trigonometry angle range -π ≤ α ≤ π in radians means angle α is

To answer the question, we need to know what a trigonometric angle range is

A trigonometric angle range is the range of values which the trigonometric angle can have

Since we need to find the meaning of the  trigonometry angle range -π ≤ α ≤π.

We know that

Since α is in the range -π ≤ α ≤ π = -180° ≤ α ≤ 180°, this implies that the angle α is

So, the  trigonometry angle range -π ≤ α ≤ π in radians means that angle α is

Step-by-step explanation:

By the geometric mean theorem,

[tex]\frac{x}{36}=\frac{64}{x}\\\\x^{2}=36 \cdot 64\\\\x=\sqrt{36 \cdot 64}\\\\x=\sqrt{36} \sqrt{64}=48[/tex]

To eliminate the biggest common factor, use the distributive property: Solution: 16 + 36 = 4 (4 + 9)

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Due to that,

To remove the most significant common factor, we must use the distributive property.

Given expression:16 + 36

1, 2, 4, 8, and 16 make up the number 16.

The probability that the randomly selected student is female or Physics major is 0.625.

Given Information

Total number of students = 40

Number of Physics major out of the total students, P = 15

Number of females in the class, F = 16

Number of females that are Physics major, (P∩F) = 6

We have to find the probability P(P∪F).

Calculating the Probability

Probability of Physics major students, P(P) = 15/40

= 0.375

Probability of female students, P(F) = 16/40

= 0.4

Probability of female students who are Physics major, P(P∩F) = 6/40

= 0.15

Since, we know that,

P(P∪F) = P(P) + P(F) - P(P∩F)

∴ P(P∪F) = 0.375 + 0.4 - 0.15

P(P∪F) = 0.625

Thus, the probability that the randomly selected student will be a Physics major or a female is 0.625

A=12

B = 3

C= 2

substitute A, B and C into equation (1).

Answer:

The given lines are perpendicular.

Step-by-step explanation:

In the question, two lines are given as line 1 passes through (0,5) and (3,3). Whereas, line 2 passes through (1,-5) and (3,-2).

It is required to find the slope of given lines and figure out whether they are perpendicular, parallel or neither.

To solve this question, first find the slope of both lines. Check if their product is equal to -1, then they are perpendicular. If the slopes are equal the lines are parallel.

Step 1 of 2

Find the slope of first line.

[tex]$$\begin{aligned}&m_{1}=\frac{3-5}{3-0} \\&m_{1}=\frac{-2}{3} \\&m_{1}=-\frac{2}{3}\end{aligned}$$[/tex]

Step 2 of 2

Find the slope of first line.

[tex]$$\begin{aligned}&m_{2}=\frac{-2-(-5)}{3-1} \\&m_{2}=\frac{3}{2} \\&m_{2}=\frac{3}{2}\end{aligned}$$[/tex]

And

[tex]$$\begin{aligned}&m_{1} m_{2}=-\frac{2}{3}\left(\frac{3}{2}\right) \\&m_{1} m_{2}=-1\end{aligned}$$[/tex]

Since, both slopes are reciprocals .

Therefore. the lines are perpendicular.

Step-by-step explanation:

f(x) = y = -1/2 × sqrt(x + 3), x >= -3

-2y = sqrt(x + 3)

4y² = x + 3

x = 4y² - 3

and now we need to rename x to y and y to x to make it a "normal" function :

y = 4x² - 3

since in the original function x >= -3, this gave us y <=0.

and therefore (remember the x of the inverse function actually stands for the y of the original function) the limit for the inverse function is x <= 0.

so, again, the full answer is

f^-1(x) = 4x² - 3, x <= 0

Answer:

5

Step-by-step explanation:

→ Let x = √20 + √20 .....

x

→ Square both sides

x² = 20 + √20 +√20 + √20

→ Replace √20 +√20 + √20 with x

x² = 20 + x

→ Move everything to the left hand side

x² - 20 - x = 0

→ Factorise

( x + 4 ) ( x - 5 )

→ Solve

x = -4 , 5

→ Discard negative result

x = 5

Note that

[tex]\left(\sqrt{x+a} + b\right)^2 = \left(\sqrt{x+a}\right)^2 + 2b \sqrt{x+a} + b^2 = x + 2b \sqrt{x+a} + a+b^2[/tex]

Taking square roots on both sides, we have

[tex]\sqrt{x+a} + b = \sqrt{x + 2b \sqrt{x+a} + a+b^2}[/tex]

Now suppose [tex]a+b^2=0[/tex] and [tex]2b=1[/tex]. Then [tex]b=\frac12[/tex] and [tex]a=-\frac14[/tex], so we can simply write

[tex]\sqrt{x-\dfrac14} + \dfrac12 = \sqrt{x + \sqrt{x - \dfrac14}}[/tex]

This means

[tex]\sqrt{x-\dfrac14} = -\dfrac12 + \sqrt{x + \sqrt{x - \dfrac14}}[/tex]

and substituting this into the root expression on the right gives

[tex]\sqrt{x - \dfrac14} + \dfrac12 = \sqrt{x - \dfrac12 + \sqrt{x + \sqrt{x - \dfrac14}}}[/tex]

and again,

[tex]\sqrt{x - \dfrac14} + \dfrac12 = \sqrt{x - \dfrac12 + \sqrt{x - \dfrac12 + \sqrt{x - \dfrac14}}}[/tex]

and again,

[tex]\sqrt{x - \dfrac14} + \dfrac12 = \sqrt{x - \dfrac12 + \sqrt{x - \dfrac12 + \sqrt{x - \dfrac12 + \sqrt{x - \dfrac14}}}}[/tex]

and so on. After infinitely many iterations, the right side will converge to an infinitely nested root,

[tex]\sqrt{x - \dfrac14} + \dfrac12 = \sqrt{x - \dfrac12 + \sqrt{x - \dfrac12 + \sqrt{x - \dfrac12 + \sqrt{x - \dfrac12 + \sqrt{\cdots}}}}}[/tex]

We get the target expression when [tex]x=\frac{41}2[/tex], since [tex]\frac{41}2-\frac12=\frac{40}2=20[/tex], which indicates the infinitely nested root converges to

[tex]\sqrt{20+\sqrt{20+\sqrt{20+\sqrt{\cdots}}}} = \sqrt{\dfrac{41}2 - \dfrac14} + \dfrac12 \\\\ ~~~~~~~~ = \sqrt{\dfrac{81}4} + \dfrac12 \\\\ ~~~~~~~~ = \dfrac92 + \dfrac12 = \dfrac{10}2 = \boxed{5}[/tex]

Step-by-step explanation:

3/4

The slope of a line describes the steepness of a line, as well as the direction.

Slope-Intercept Form

To answer the question, we first need to find the slope of the original line. This line is represented in the slope-intercept form, which is y=mx+b.

So, using this information we can say that the slope is 3/4.

Parallel Lines

Parallel lines are 2 lines that will never intersect. You can tell if 2 lines are parallel by their slopes. All parallel lines have equal slopes.

This means that the slope of a line parallel to y = 3/4x + 2 must be 3/4 as well.

Answer: Draw a line through (0,5) and (1,2)

The graph is shown below.

=====================================================

Reason:

The equation y = -3x+5 is in the form y = mx+b

m = -3 = slope

b = 5 = y intercept

The y intercept is where the graph crosses the y axis. In this case, it's at (0,5). This is one point needed.

Another point can be found by going down 3 and to the right 1 to arrive at (1,2). The motion "down 3, right 1" is from the slope of -3/1.

Therefore, this line goes through (0,5) and (1,2)

-------------

Another approach:

Plug in x = 0 to get...

y = -3x+5

y = -3(0) + 5

y = 5

The input x = 0 leads to the output y = 5

This tells us the point (x,y) = (0,5) is on the line.

Repeat for x = 1

y = -3x+5

y = -3(1)+5

y = 2

So (1,2) is another point on the line.
