Can someone help me find the sequence
Answers
Answer: the answer is b, thank me later
Answer:
The answer is option A
Step-by-step explanation:
The formula is
[tex]a(n + 1) = a(n) + 6[/tex]
a(1) = 11
The second term will be
a( 1 + 1) = a(1) + 6
a(2) = 11 + 6
= 17
The next term will be
a( 2 + 1) = a(2) + 6
a(3) = 17 + 6
= 23
The next term will be
a(3 + 1) = a(3) + 6
a(4) = 23 + 6
= 29
The next term will be
a(4 + 1) = a(4) + 6
a(5) = 29 + 6
= 35
So the sequence is
11 , 17 , 23 , 29 , 35

The triangle ABC is a right triangle so we will use the Pythagorian theorem
c^2 =5^2 + 8^2
c^2 = 25 + 64
c^2 = 89
c = 9.43
We khow that the sum of a triangle's angles is 180°
So B+90+58= 180
B+ 148 = 180
B = 180-148
B = 32°

Write an equation of the line passing through the given point and satisfying the given condition. Give the equation (a) in slope-intercept form and (b) in standard form.
(6, 2); parallel to 8x - y = 4
(a) Write the equation of the line in slope-intercept form.
(Simplify your answer. Use integers or fractions for any numbers in the equation.)
Answers
Answer:
(a) y=8x-46
(b) 8x-y=46
Step-by-step explanation:
-y=-8x+4
y=8x+4
We know that 8 is the slope, and if we need a equation parallel to this line, then it will have the same slope.
Substitute (6,2)
2=8(6)+b
2=48+b
b=-46
The final answer is y=8x-46

Triangle ABC is described below. Find all possible values for B, C, and c.
A= 121.59, a = 27.9 cm, b = 52.6 cm
Apply the rules regarding the use of significant digits to each angle and
length after all computations are complete.
Answers
Answer:
c = 27.9
B = 62.13°
C = 89.90°
Step-by-step explanation:
We are given the following values:
A= 121.59°, a = 27.9 cm, b = 52.6 cm
a) Finding side c
We would use Pythagoras Theorem
c² = a² + b²
c = √(a² + b²)
c = √(27.9² + 52.6²)
c = 59.54cm
≈ Approximately = 59.5cm
b) Finding B
We would be using Cosine rule to find Angle B
Cos B = a² + b² - c²/2ab
B = arc cos ( a² + c² - b²/2ac)
B = arc cos( 27.9² + 59.5² - 52.6²/ 2 × 27.9 × 59.5)
B = 62.13268°
B = 62.13°
c) Finding C
We would be using Cosine rule to find Angle C
Cos C = a² + b² - c²/2ab
C = arc cos ( a² + b² - c²/2ab)
C = arc cos( 27.9² + 52.6² - 59.5²/ 2 × 27.9 × 52.6)
C = 89.9°
At the grocery store, you can purchase lemons at 2 for $0.99. you can also buy a bag of 6 lemons for $2.50. Which is the better buy?
Answers
Answer:
Purchasing the bag of 6 lemons is the better buy.
Step-by-step explanation:
There are two ways that we can do this: find the unit rate or find how the LCM.
---
The first way is more orthodox, and you should definitely use it in harder problems. We can set up two ratios like so.
2 : 0.99
6 : 2.5
Let's simplify the ratios so the left side is one.
2 : 0.99 = 1 : 0.495 by dividing both sides by 2.
6 : 2.5 = 1 : 0.41666... by dividing both sides by 6.
Comparing the two ratios, we can conclude that the second one is smaller, therefore the bag of 6 lemons costs less.
---
The second way, although not very efficient with big numbers, works well with small numbers like these.
First, we need to find the LCM, or the least common multiple. The LCM of 2 and 6 is 6, as 6 is a multiple of both 2 and itself.
Now we must make the amount of lemons match each other so we can compare the price.
2 : 0.99 = 6 : 2.97 by multiplying by 3.
The second ratio stays the same.
2.50 is smaller than 2.97, so the second ratio is smaller than the first, reaching our previous conclusion.

Simply plug the coordinates into the distance formula:
[tex]d=\sqrt{(5-3)^2+(4+1)^2} = \sqrt{29}[/tex]
[tex]d=\sqrt{(4-2)^2+(5-3)^2} = 2\sqrt{2}[/tex]

If cos x=−6/7, and 90°
Answers
Answer: 0.4693877
Step-by-step explanation:
Given that:
cos x=−6/7,
From trigonometry :
Cosx + sinx = 1
Cos2x = cos(x + x)
Recall the double angle identity:
Cos2x = 2cos^2x - 1
Sin2x = 1 - 2sin^2x
Since cosx = - 6/7
Then
Cos2x = 2cos^2x - 1
Cos2x = 2cosx^2 - 1
Cos2x = 2(-6/7)^2 - 1
Cos2x = 2(36/49) - 1
Cos2x = 2 * (72/98) - 1
Cos2x = (2 * 0.7346938) - 1
Cos 2x = ( 1.4693877 - 1)
Cos2x = 0.4693877

There are two points on the circle A and B. Each point has a light which is switched on. Bob starts at the point A and moves on the circle. Each time when he reaches to a point A or B he does the following: 1. If he is on A and the light on B is switched on then he changes the light on A (if it is switched off then he switches on, and vice-versa), 2. If he is on A and the light on B is switched off then he doesn't change the light on A. 3. If he is on B and the light on A is switched on then he changes the light on B (if it is switched off then he switches on, and vice-versa), 4. If he is on B and the light on A is switched off then he doesn't change the light on B. Bob starts from the point A (first step). What will be the position of lights after the 107th step.
(A) A and B are switched on
(B) A is switched on and B is switched off
(C) A is switched off and B is switched on
(D) A and B are switched off
Answers
Answer:
A will be switched off and B will be switched on.
Step-by-step explanation:
Because there are four different positions this can be in and there are 107 steps, we can divide 107 by four.
107 divided by four is 26 and the remainder is 3. That means the steps have gone around 26 times, and we are now on the third step before we complete the 27th cycle. The third step is C, where A is switched off and B is on.

Answer:
The mean boiling temperature of the tap water is 2°C less than hat of the mixture of salt water.
Step-by-step explanation:
The complete question is attached below.
From the provided data it can be seen that the distributions of boiling temperatures, in degrees Celsius, of both tap water and a mixture of salt water are approximately symmetric.
It is known that, for a symmetric distribution,
Mean = Median = Mode
The median for the two distributions are:
Median (Tap water) = 100°C
Median (Mixture of salt water) = 102°C
Then the mean for the two distributions would be:
Mean (Tap water) = 100°C
Mean (Mixture of salt water) = 102°C
So, the mean boiling temperature of the tap water is 2°C less than hat of the mixture of salt water.

Each new triangle shown below has one more dot per side than the previous triangle. What is the total number of dots on the 200th triangle of this sequence? first term has 6 second term has 9 third has 12 PLS HELP WILL MARK BRAINLIEST
Answers
Answer: 603 dots
Step-by-step explanation:
Triangle always has 3 sides. Given that
Each new triangle shown below has one more dot per side than the previous triangle. That means if first term has 6 dot, the second term will have 9 dots and third has 12 dots.
The difference between first and the second is the same with the difference between third and the second. That is,
First term a = 6
Difference d = 3
Number of term n = 200
This is arithmetic progression. We can come up with a formula:
Tn = a + ( n - 1 )d
Substitute all the parameters into the formula
Tn = 6 + ( 200 - 1 )×3
Tn = 6 + 199×3
Tn = 6 + 597
Tn = 603 dots
Therefore, the total number of dots on the 200th triangle of this sequence is 603 dots.

What is depth perception?Depth perception is the way in which some animals, such as humans, can tell if a object is close or far away from them.
Depth perception is the ability that humans have to perceive depth. With depth perception animals are able to see something in three dimensions. The configuration of the eyes allows animals to see depth.
Having two eyes that is having binocular vision gives animals an accurate sense of depth.
Animals have evolved in such a way that gives us depth perception. In order for animals to survive in a three dimensional world depth perception is vital.
