What is the measure of AC ? Enter your answer in the box. ° Circle with inscribed angle A B C. Angle A B C is 3 x minus 1.5 degrees. The intercepted arc A C is 3 x plus 9 degrees.
Answers
[tex](3x-1.5)=\frac{1}{2}(3x+9)[/tex]. Distribute the 1/2:
[tex]3x-1.5=\frac{1}{2}*3x+\frac{1}{2}*9 \\3x-1.5=\frac{1}{2}*\frac{3x}{1} + \frac{1}{2}*\frac{9}{1} \\3x-1.5=\frac{3x}{2}+\frac{9}{2} \\3x-1.5=1.5x+4.5[/tex]
We cannot have a variable on both sides of the equation, so cancel the 1.5x to avoid negatives:
[tex]3x-1.5-1.5x=1.5x+4.5-1.5x[/tex]
Combine like terms:
[tex]1.5x-1.5=4.5[/tex]
Cancel the -1.5 by adding:
[tex]1.5x-1.5+1.5=4.5+1.5 \\1.5x=6[/tex]
Divide both sides by 1.5:
[tex]\frac{1.5x}{1.5}=\frac{6}{1.5} \\x=4[/tex]
Since AC is 3x+9, we substitute 4 in for x:
3*4+9=12+9=21°
Use the Inscribed Angle theorem to get the measure of AC. The intercepted arc AC is [tex]21^{\circ}[/tex].
Given,
The inscribed angle [tex]\angle ABC[/tex] is [tex]3x-1.5[/tex].
And the Intercepted arc AC is [tex]3x+9[/tex].
What is the Inscribed Angle theorem?We know that, Inscribed Angle Theorem stated that the measure of an inscribed angle is half the measure of the intercepted arc.
So,
[tex]3x-1.5=\frac{1}{2} (3x+9)[/tex]
[tex]2 (3x-1.5)=3x+9[/tex]
[tex]6x-3.0=3x+9[/tex]
[tex]6x-3x=9+3[/tex]
[tex]3x=12\\x=4[/tex]
Since the intercepted arc AC is [tex]3x+9[/tex], putting the value of [tex]x=4[/tex] we get,
intercepted arc AC is [tex]21^{\circ}[/tex].
Hence the intercepted arc AC is [tex]21^{\circ}[/tex].

F(x) = (x+2)^3 = the highest power for this type turn out will be x^3
the other part is (x^2 - 7x + 3)^4, the highest power for this part will be x^8
since (x+2)^3(x^2-7x +3)^4 = the highest power of first part x^3 second part x^8
x^3 * x^8 = x^11 that result in 11 roots
This type of math, you don't need to configure the whole problem, you just need to know the basic rules of power of a number. For example, (x^2)^3, then 2*3 = 6 make x^6.

how many triangles have the following measurements? A=38, a=432, b=382
Answers
_____
You know this because the given angle is opposite the longest given side. You only have ambiguous cases if the given angle is opposite the shorter of two given sides.
Using the Law of Sines, we determined that it is possible to form one triangle with the given measurements A=38°, a=432, and b=382. The calculation includes finding angle B and angle C, ensuring all triangle conditions are met.
To determine how many triangles can have the given measurements (A=38°, a=432, b=382), we need to check if these values satisfy the triangle inequalities and if they can form a possible triangle using the Law of Sines.
First, let's use the Law of Sines which states that:
sin(A)/a = sin(B)/b = sin(C)/c
Given:
A = 38° (angle)a = 432 (side opposite to angle A)b = 382 (side opposite to angle B)We can calculate angle B using:
sin(B) = (b × sin(A)) / a
sin(B) = (382 × sin(38°)) / 432 ≈ 0.556
Finding the arc sine of 0.556, we get:
B ≈ 33.8°
Now, we find angle C:
C = 180° - A - B ≈ 180° - 38° - 33.8° = 108.2°
Using the Law of Sines again to find side c:
c = (a × sin(C)) / sin(A)
c = (432 × sin(108.2°)) / sin(38°) ≈ 676.85
Thus, it's possible to form one such triangle with the given conditions.

find the measures of two angles one positive and negative that are coterminal with pi/2
Answers
Answer: The required measures of two angles one positive and negative that are co-terminal with [tex]\dfrac{\pi}{2}[/tex] are [tex]-\dfrac{3\pi}{2}[/tex] and [tex]\dfrac{5\pi}{2}.[/tex]
Step-by-step explanation: We are given to find measures of two angles one positive and negative that are co-terminal with [tex]\dfrac{\pi}{2}.[/tex]
Let x and y represents the positive and negative co-terminal angles respectively.
We know that
the measures of any two co-terminal angles differ from each other by a multiple of [tex]2\pi.[/tex]
So, the values of x and y can be found as follows :
[tex]x=\dfrac{\pi}{2}-2\pi=-\dfrac{3\pi}{4},\\\\\\y=\dfrac{\pi}{2}+2\pi=\dfrac{5\pi}{2}.[/tex]
Thus, the required measures of two angles one positive and negative that are co-terminal with [tex]\dfrac{\pi}{2}[/tex] are [tex]-\dfrac{3\pi}{2}[/tex] and [tex]\dfrac{5\pi}{2}.[/tex]
Final answer:
The positive coterminal angle with π/2 is 5π/2, and the negative coterminal angle is -3π/2; both angles are found by adding and subtracting 2π radians from the original angle.
Explanation:
To find the measures of two angles, one positive and one negative, that are coterminal with π/2, we need to add and subtract 2π (360 degrees) to the original angle since the angles are coterminal when they share the same initial and terminal sides and differ by a full circle (360 degrees) or a multiple thereof. The angle π/2 radians is equivalent to 90 degrees, so adding 2π radians (360 degrees) gives us a positive coterminal angle, and subtracting 2π radians (360 degrees) gives us a negative coterminal angle.
Positive coterminal angle: π/2 + 2π = 5π/2.
Negative coterminal angle: π/2 - 2π = -3π/2.

Fifty people are surveyed at a state fair. Of the 50 people, 30 like funnel cake and 25 like fried oreos. Twenty people like both funnel cakes and fried oreos. Use a Venn Diagram to organize the data and answer the questions. How many people like either funnel cake or fried oreos?
Answers
55
When using a Venn diagram to determine how many people like either funnel cake or fried Oreos out of a survey of 50, after subtracting the 20-person overlap from each individual preference to avoid double counting, the total number liking either is found to be 35 people.
To determine how many people like either funnel cake or fried Oreos, we need to use the concept of set union from Venn diagrams. First, we draw two overlapping circles, one for people who like funnel cake and another for those who like fried Oreos.
The overlapping area represents people who like both. Given that 30 people like funnel cake and 25 like fried Oreos, with a 20-person overlap liking both, we add the individual preferences and subtract the overlap to avoid double counting.
The representation is:
Number liking funnel cake only: 30 - 20 = 10
Number liking fried Oreos only: 25 - 20 = 5
Number liking both: 20
Adding these, the total number liking either funnel cake or fried Oreos is 10 + 5 + 20 = 35 people.

Answers
340 miles with 8 gallons.
A gallon costs $4, so 8 gallons cost 8 * $4 = $32.
$32 per 340 miles = $32/340 = $0.0941/mile = 9.4 cents/mile
After mechanic:
350 miles with 7 gallons.
7 gallons cost 7 * $4 = $28.
$28 per 350 miles = $28/350 = $0.08/mile = 8 cents/mile
The difference is 9.4 - 8 = 1.4.
To the nearest cent, round 1.4 to 1.
