Find the next term of the geometric sequence 2/27 , 2/9 , 2/3 , .. Please help
Answer:
2/1 or 2Step-by-step explanation:
They are dividing the denominator by 3. So, the answer is 2/1 or basically the number 2.
For example,
27/3 = 9
9/3 = 3
3/3 = 1The last math shows how I got the answer.
Hope this helps!
Answer:
2
Step-by-step explanation:
The sequence is multiplying by 3 each time. 2/27 *3= 2/9
2/9 *3 is 2/3.
2/3*3= 2
2 is the next term
mary thinks the triangle is equilateral. how would you support or dispute her conjecture?
Answer:
Use the distance formula to calculate the length of all three sides, and check whether all sides are congruent.
Step-by-step explanation:
An equilateral triangle would have three sides that are all the same length, out of these options, only using the distance formula to calculate the length of all three sides and checking whether they are all congruent will make sure that the triangle is equilateral instead of just isosceles.

Which equation represents a line that passes through (2, -1/2) and has a slope of 3?
y-2 = 3(x + 1/2)
y-3 = 2(x + 1/2)
y+1/2= 3(x - 2)
y + 1/2 = 2(x – 3)
Answer:
y+1/2= 3(x - 2)
Step-by-step explanation:
The slope can be seen to be 3 by factoring out each of the right sides. Only a and c have a slope of 3. Next if the point (2,-1/2) is plugged into the equation of c then you get an answer of 0=0. Beacuse both sides are equal when the point desired is plugged in it is the correct answer.

Sam uses 2/3 cup of sugar to make cookies. How many cups will Sam use to make five batches. Write your answer in two ways. Improper fraction and mixed number
Answer:
Improper fraction = 10/3 cups
Mixed fraction = 3 1/3 cups
Step-by-step explanation:
Given;
Sam uses 2/3 cup of sugar to make cookies
Rate = 2/3 cup per batch
To make 5 batches, he would need;
Amount = number of batches × rate per batch
Amount = 5 batches × 2/3 cups per batch
Amount of sugar he would need = 10/3 or 3 1/3 cups

use a power reduction identity to simplify 8cos^4x
The simplified value is 8*cos^4(x) = 3+ 4 cos2x + cos 4x.
What is power reduction identity?The trigonometric power reduction identities allow us to rewrite expressions involving trigonometric terms with trigonometric terms of smaller powers. This becomes important in several applications such as integrating powers of trigonometric expressions in calculus.
Given:
Using the power reduction identity, we have that:
cos² x= 1/2( 1+ cos 2x)
cos^4(x) = (cos² x)²= (1/2( 1+ cos 2x))²
cos^4(x) = 1/4( 1+ cos² 2x+ 2 cos (2x))
Again, cos² 2x= 1/2( 1+ cos 4x)
cos^4(x) = 1/4( 1+ 1/2( 1+ cos 4x)+ 2 cos (2x))
cos^4(x) = 1/4( 1+ 1/2 +1/2 cos 4x+ 2 cos (2x))
cos^4(x) = 1/4( 3/2 + 2 cos2x + 1/2 cos 4x)
8*cos^4(x) = 8*1/4( 3/2 + 2 cos2x + 1/2 cos 4x)
8*cos^4(x) = 2( 3/2 + 2 cos2x + 1/2 cos 4x)
8*cos^4(x) = 3+ 4 cos2x + cos 4x

What is the value of x?
Answer:
x = 9
Step-by-step explanation:
→Looking at the angles, you can see that a right angle is formed. This means that there must be another right angle (90 degrees) formed with the numbers. You can set up the equation, like so:
3x + 6 + 57 = 90
→Add like terms (6 and 57):
3x + 63 = 90
→Subtract 63 from both sides:
3x = 27
→Divide both sides by 3:
x = 9
Answer:
x=9
Step-by-step explanation:
a right angle is 90 degrees
90-57= 33
33-6=27
27/3 = 9

Answer:
The alternative interior angles theorem.
Step-by-step explanation:
The alternate interior angles theorem states that, when two parallel lines are cut by a transversal, then the alternate interior angles are congruent.
The Bermuda Triangle is a region in the Atlantic Ocean where many ships, planes, and people have apparently disappeared without a reasonable explanation. It lies just off the coast of the United States. And it’s angles are located at Bermuda (Angle b), San Juan (angle s), and Miami (angle m).

Find the distance between the points.
(-3,2) and (0,2)
The distance is
Answer:
d=3
Step-by-step explanation:
by using distance formula
d=√(x2-x1)²+(y2-y1)²
let the points be A(-3,2) B(0,2)
d=√(0--3)²+(2-2)²
d=√(+3)²+(0)²
d=√9
d=3
What is the scale factor of Xyz to UVW?
Answer & Step-by-step explanation:
In order to solve this problem, we are going to have to divide. Since the triangles are similar, then that means that we are going to have to find the ratio between the sides which will also be our scale factor.
We can divide 75 by 15 since they are corresponding sides. Once we find the ratio between the sides, then we can conclude that the scale factor would be that number.
75 / 15 = 5
So, the scale factor of XYZ to UVW is 5.
The scale factor of [tex]Xyz[/tex] to [tex]UVW[/tex] is 5.
What is scale factor?The ratio that we get when you divide corresponding side lengths of similar figures is called the scale factor.
According to the given question.
We have a two triangles Xyz and UVW. And both the triangles are similar to each other.
In triangle Xyz we have
[tex]Xy = 60[/tex]
[tex]yz = 75[/tex]
and
[tex]zX = 90[/tex]
Also, in triangle UVW we have
[tex]UV = 12[/tex]
[tex]VW = 15[/tex]
and, [tex]WU = 18[/tex]
Therefore, the scale factor of Xyz to UVW is given by
[tex]\frac{Xy}{UV} =\frac{yz}{VW} =\frac{zX}{WU}[/tex]
⇒ [tex]\frac{60}{12} =\frac{75}{15} =\frac{90}{18} =5[/tex]
Hence, the scale factor of [tex]Xyz[/tex] to [tex]UVW[/tex] is 5.
Thus option B is correct.

In triangle ABC, AB = 6 cm, BC = 13 cm and angle ACB = 23°.
Calculate angle BAC, which is obtuse.
Answer:
angle BAC = 57.84°
Step-by-step explanation:
To find angle BAC given AB=6cm BC= 13 cm and ACB=23°
we will follow the steps below;
we can use the sine formula to solve the problem given
[tex]\frac{sin A}{a}[/tex] = [tex]\frac{sin C}{c}[/tex]
from the question given;
A = ?
C = 23°
c=AB = 6 cm
a=BC = 13 cm
substitute the values into the formula above
[tex]\frac{sin A}{a}[/tex] = [tex]\frac{sin C}{c}[/tex]
[tex]\frac{sin A}{13}[/tex] = [tex]\frac{sin 23}{6}[/tex]
cross -multiply
6 sinA = 13 sin23°
sin A = 13 sin23° / 6
sin A = 0.84658
take the [tex]sin^{-1}[/tex] of both-side
[tex]sin^{-1}[/tex] sin A = [tex]sin^{-1}[/tex] (0.84658)
on the left-hand side of the equation [tex]sin^{-1}[/tex] will cancel-out sin leaving us with just A
A = [tex]sin^{-1}[/tex] (0.84658)
A ≈ 57.84°
angle BAC = 57.84°
