According to this diagram, what is tan 67° ?
Answer:
B. 12/5
Step-by-step explanation:
tan=opp. leg/adj. leg
tan 67= 12/5
According to this diagram, the tan67° is 12/5.
What is the tan67° from the given diagram?In Trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.In other words, it is the ratio of sine and cosine function of an acute angle such that the value of cosine function should not equal to zero.⇒ tan67° = perpendicular/base = 12/5.
Hence, the value of tan67° is 12/5.

which object has no line segments?
A. Rectangle
B. Hexagon
C. Circle
D. Pentagon
Answer:
C. Circle
Step-by-step explanation:
A, B, and D are all composed of straight line segments. However a circle is one continuous, rounded line (not a segment).
A circle is an object that has no line segments.
Why circle has no line segment?A circle doesn't have line segments because it is a curve that is not made up of straight lines.A circle doesn't have a line segment because a line segment is defined as a portion of a straight line of infinite thickness between two points whereas a circle is not having a single straight line.A circle is curved it cannot be formed from a line segment and thus does not fit the conditions needed to be a polygon.The only line segment that a circle has is inside it i.e., the diameter is the one and only line segment inside the shape.Hence, a circle is an object that has no line segment.
Therefore, Option C is the correct answer.

if it cost $6 to fill a gas tank in 1970 for $0.36, how much would it have cost to fill the same tank in 2010 for $2.84
7.8889 I think so so I divided 2.84%39=7.8889
Final answer:
To find the 2010 cost of filling a gas tank based on 1970 prices, divide the 1970 total cost by the price per gallon to find the number of gallons, then multiply that by the 2010 price per gallon. The cost to fill the same tank in 2010 would be $47.34.
Explanation:
The question is asking to calculate the cost of a full tank of gas in 2010 based on the cost from 1970. To find out how much it would cost in 2010, we need to first determine the number of gallons that could be bought for $6 in 1970 at $0.36 per gallon. This can be calculated by dividing $6 by $0.36, which equals 16.67 gallons (approximately). Now, assuming the tank size has not changed, to find out the cost in 2010, we multiply the number of gallons by the 2010 price per gallon. Thus, 16.67 gallons multiplied by $2.84 per gallon equals $47.34.

sinA = [tex]\frac{2\sqrt{19} }{20}[/tex] = [tex]\frac{\sqrt{19} }{10}[/tex]
--------------------------------------------------------------------------------------------
cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex], thus
cosA = [tex]\frac{18}{20}[/tex] = [tex]\frac{9}{10}[/tex]

tanA = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex], thus

Translate ∆ABC by moving it 5 units to the right and 2 units up.
To translate a triangle by moving it 5 units to the right and 2 units up, you add 5 to the x-coordinates and 2 to the y-coordinates of all its vertices.
Explanation:To translate riangle ABC by moving it 5 units to the right and 2 units up, you would perform the following steps:
Select riangle ABC.Move each point of riangle ABC 5 units to the right. This is done by adding 5 to the x-coordinate of each vertex of the triangle.Then, move each point of riangle ABC 2 units up. This is done by adding 2 to the y-coordinate of each vertex of the triangle.The new position of riangle ABC is the result of this translation.This transformation doesn't change the shape or size of riangle ABC; it merely repositions it on the coordinate plane.

Which expression is equivalent to (-18)-64n
A)-2(9-32n)
B)2(9-32n)
C)-2(9+32n)
D)2(9+32n)
Answer:
C)-2(9+32n)
Step-by-step explanation:
The given expresion is
[tex] - 18 - 64n[/tex]
We can rewrite this expression as:
[tex] - 2 \times 9 + - 2 \times 32n[/tex]
We factor -2 to obtain:
[tex] - 2(9 + 32n)[/tex]
Note that, we can use the distributive property to obtain:
[tex] - 2(9 + 32n) = - 18 - 64n[/tex]
Therefore the correct answer is C)-2(9+32n)
The expression equivalent to (-18)-64n is option A: -2(9-32n). This is because when you distribute the -2 across the terms in the parentheses, it gives you the original expression.
Explanation:To find which expression is equivalent to (-18)-64n, we can factor out the greatest common factor (GCF) from each term. The GCF of -18 and -64n is -2. Thus, when we factor out -2, we are left with:
(-18)-64n = -2(9 + 32n).
But we have to pay attention to our signs; we should distribute -2 within the parentheses to check our result:
-2 × 9 = -18
-2 × 32n = -64n
Thus, option A -2(9-32n) is the correct equivalent expression, as the negative sign in front of the parentheses will switch the signs of the terms inside when distributed. Options B, C, and D either lack the necessary negative sign or have the incorrect sign for 32n.

Step-by-step explanation:
[tex]\dfrac{\tan \theta }{\sin^{2} \theta + \cos^{2} \theta}[/tex]
Use the trigonometric identity
[tex]\sin^{2}\theta + \cos^{2}\theta = 1[/tex]
Then,
[tex]\dfrac{\tan \theta }{\sin^{2} \theta + \cos^{2} \theta} = \dfrac{\tan \theta }{1} = \boxed{\tan \theta}[/tex]
The correct option is d. tan θ. The simplified expression is [tex]\(\tan\ \theta\)[/tex].
The expression you provided is:
[tex]\[ \frac{\tan\ \theta}{\sin^2 \theta + \cos^2 \theta} \][/tex]
We know that [tex]\(\sin^2 \theta + \cos^2 \theta = 1\)[/tex] due to the Pythagorean identity for sine and cosine.
So, the expression simplifies to:
[tex]\[ \frac{\tan\ \theta}{1} = \tan\ \theta \][/tex]
Therefore, the correct simplified expression is [tex]\(\tan\ \theta\)[/tex].

Which net represent the solid?
Answer: Figure one
Step-by-step explanation: this is a very very easy question and i will explaing it for you :) So basically all your doing is folding a peice of paper. If you look closley at figure two you can see that if you fold that it wont even turn into a shape. And if you look at figure three it has uneven sides when a square has all even sides. So your only valid option would be figure one because that would fold in to a square

Which of these triangle pairs can be mapped to each other using a reflection and a translation?
Answer:
second option
Step-by-step explanation:
The triangle pairs that can be mapped to each other using a reflection and a translation are option (b).
The following statement will clarify how that triangle pair is mapped to each other using a reflection and a translation:A translation moves a shape left or right and/or up or down.The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have shifted in one or more directions. There is no change in the shape.In Geometry, a reflection is known as a flip.A reflection is a mirror image of any given shape.Reflection is flipping an object across a line without changing its size or shape whereas Translation is sliding a figure in any direction without changing its size, shape, or orienattion.To graph a translation, perform the same change for each point. We can identify a reflection by the changes in its coordinates.Hence, the correct answer is option (b).

A regular octagon is inscribed in a circle with a radius of 5 feet. What is the area of the octagon
Answer:
70.58 ft²
Step-by-step explanation:
One pie-shaped sub-area of this octagon has two sides of length 5 ft and a central angle of 360°/8, or 45°. We need to find the area of one such sub-area and then multiply the result by 8 to find the total area of the octagon.
Picture this pie-shape, this isosceles triangle with two sides of length 5 ft and central angle 45°. Half of that angle is 22.5°. Half of the base of this triangle is 5 sin 22.5°, or 1.91; the full base length is twice that, or 3.82. the height of the triangle is 5 cos 22.5°, or 4.62.
The formula for the area of a triangle is
A = (1/2)(base)(height), which in this case is:
A = (1/2)(3.82 ft)(4.62 ft) = 8.82 ft²
and so the area of the whole octagon is 8(8.82 ft²), or 70.58 ft²
