Answer:
Step-by-step explanation: First, you isolate x, meaning only x can be on one side. you subtract 3 from both sides, getting x<4- x is less than four.
there are two graphs showing x less than four, but since this is less than and not less than/equal to, your answer is the fourth graph, where the point is open and not closed.

Find the value of the trig function indicated.
In the given triangle, we have
[tex]\tan(\theta) = \dfrac{20}{15} = \dfrac43[/tex]
Recall that
[tex]\sin^2(\theta) + \cos^2(\theta) = 1 \implies \tan^2(\theta) + 1 = \sec^2(\theta)[/tex]
Solving for [tex]\sec(\theta)[/tex], we have

Which expression represents a cube root of –8?
Answer:
C
Step-by-step explanation:
Edge2021
An expression that represents a cube root of -8 is [tex]2(cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} ))[/tex]
What is complex number?"It is combination of a real number and an imaginary number.""The complex number is of the form of a + ib, where a, b are real numbers and i = [tex]\sqrt{-1}[/tex]"How to write complex number in trigonometric form?For a complex number z = a + ib, the trigonometric form is [tex]r(cos\theta +isin\theta)[/tex]
where [tex]r=|\sqrt{a^{2} +b^{2} } |[/tex] and [tex]\theta=tan^{-1}(\frac{b}{a} )[/tex]
For given question,
We need to find the cube root of -8
[tex]\sqrt[3]{-8}[/tex]
We can write above number as complex number.
[tex]\sqrt[3]{-8}\\ =\sqrt[3]{8\times (-1)}\\ =\sqrt[3]{8}\times \sqrt[3]{-1}\\ =2 \times(-1)^\frac{1}{3}[/tex]
Consider a complex number z = -1
We can write -1 in trigonometric form as, [tex]-1=cos(\pi)+isin(\pi)[/tex]
We know, [tex](cos\theta +isin\theta)^{\frac{1}{n} }=(cos(\frac{1}{n} \theta )+isin(\frac{1}{n} \theta))[/tex]
So,
[tex](-1)^{\frac{1}{3} }\\\\=(cos\pi+i~sin\pi)^{\frac{1}{3} }\\\\=cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} )[/tex]
Therefore, an expression that represents a cube root of -8 is [tex]2(cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} ))[/tex]

A student performed the following construction for the angle bisector of ZDAE. is the student's construction correct?
Yes. The student's construction is correct because circle A and circle D are the same size.
O No. The student's construction is not correct because circle D and circle E are not the same size.
Yes. The student's construction is correct because EH = DH
O No. The student's construction is not correct because AHDH.
The correct option is b). No. The student's construction is not correct because circle D and circle E are not the same size.
What is meant by angle bisector?An angle bisector is a ray, segment, or line which divides a provided angle into two equal-sized angles. The term bisector or bisection refers to the process of dividing something into two equal parts.
In geometry, the angle bisector is the ray, line, or segment that divides a provided angle into two equal parts. An angle bisector, for example, will divide a 60-degree angle into two 30-degree angles. In other words, it separates an angle into two congruent smaller angles.Now, as per the given question;
If line AH is the angle bisector of angle DAE, circle D as well as circle E should be the same size to ensure triangle ΔHDA ≅ Δ HEA, from which ∠ DAH= ∠EAH is deduced. Angle bisector properties
Thus, the student's construction again for angle bisector of DAE is incorrect because circle D or even circle E aren't the same size.

Find the diameter of this circle.
A. [tex]2\sqrt{10}[/tex]
B. [tex]4\sqrt{10}[/tex]
C. 8
D. [tex]2\sqrt{34}[/tex]
Answer:
A
Step-by-step explanation:
From looking at the graph, you can see that the center point of the circle is at (5, -3), so to figure out the diameter, you need to find the distance of that line ( y = - 3 ) that the circle is on. The diameter is about 6 point something which in the square root form can be represented by √36.
After knowing the diameter is about 6, choice C can be eliminated.
2√10 = √40
4√10 = √160
2√34 = √136
After expanding the square root, we can know that the closest option is A.
Check the picture below.
so we know the circle has that center and passes through (2 , -2), let's find its radius, keeping in mind that diameter = 2 * radius.
[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-3})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(~~5 - 2~~)^2 + (~~-3 - (-2)~~)^2} \implies r=\sqrt{(5 -2)^2 + (-3 +2)^2} \\\\\\ r=\sqrt{( 3 )^2 + ( -1 )^2} \implies r=\sqrt{ 9 + 1 } \implies r=\sqrt{ 10 }~\hfill \underset{diameter}{\stackrel{(2)(r)}{2\sqrt{10}}}[/tex]

QUESTION 3 Let G and H be two events in a sample space. P(G) = 0.4, P(H) = x and P(G or H) = 0.7 3.1 For what value of x are G and H mutually exclusive? (2)
For x = 0.33, the events G and H are mutually exclusive.
Here, we are given that-
P(G) = 0.4
P(H) = x
and P(G or H) = 0.73
⇒ P(G∪H) = 0.73
Now, we know that-
P(G U H) = P(G) + P(H) - P(G ∩ H)
For any two events that are mutually exclusive, the probability that they occur at the same time is 0. Hence, if G and H are mutually exclusive, then P(G ∩ H) will be 0
⇒ 0.73 = 0.4 + x - 0
x = 0.73 - 0.4
x = 0.33
Thus, for x = 0.33, the events G and H are mutually exclusive.

Step-by-step explanation:
The pressure , P, measured in pounds per square inch (psi ) on an object under water varies directly with its depth , d measured in feet . If the pressure on an object at a depth of 20 feet is 8.6 psi, what is the pressure on an object at a depth of 25 feet ?
Answer:
10.75 psiStep-by-step explanation:
Let the equation be:
y = kx, where y- pressure, k- constant, x - depthFor the depth of 20 ft, the equation is:
8.6 = 20kk = 8.6/20k = 0.43For the depth of 25 ft, the pressure is:

Takis Tortilla Chips Variety Pack 18 Count
what is the unit rate of the product
Answer:
About 42 cents
Step-by-step explanation:
What we know:
An 18-count variety pack of Taki's chips costs $7.49.
To find the unit rate divide 7.49 by 18, and round to the nearest cent.
7.49/18
Before we do that, what is 749/18?
749/18 = 41 11/18
Divide that by 100 to get your answer
41.61111/100 = 0.4161111, which rounds to 42 cents.
BD bisects angle ABC. Solve for x and find m angle ABC.
m angle ABD = 6x-8, m angle CBD = 3x + 4
Answer:
The value of x = 4
so
m ∠ABD = 6x-8 = 6(4)-8 = 24-8 = 16m∠CBD = 3x+4 = 3(4)+4 = 12+4 = 16Step-by-step explanation:
We know that an angle bisector bisects the angle into two equivalent angles.
When BD bisects angle ABC, it forms two equivalent angles which are:
m∠ABDm∠CBDsuch as
m∠ABD = m∠CBD
as
m ∠ABD = 6x-8
m∠CBD = 3x+4
so the equation becomes
m∠ABD = m∠CBD
6x-8 = 3x+4
6x - 3x = 4 + 8
3x = 12
Divide both sides by 3
x = 4
Thus, the value of x = 4
so
m ∠ABD = 6x-8 = 6(4)-8 = 24-8 = 16m∠CBD = 3x+4 = 3(4)+4 = 12+4 = 16Suppose you have 9 tubes of paint. How many distinct color groupings can you make with your paint?
9514 1404 393
Answer:
511
Step-by-step explanation:
Each tube can be included in the mix, or not. There are 2^9 = 512 possible subsets of a set of 9 objects, including the complete set and the empty set. The empty set will not make a color, so there are ...
2^9 - 1 = 511 distinct color groupings that can be made
__
The assumption in the above answer is that no tube color can be made by any combination of other tube colors.* We also assume that the choice of tubes is what makes a "color grouping", and that the colors within that grouping made by using different ratios of paint quantities are not counted separately.
