Which formula represents this sequence 2,8,14...?
Answer:
[tex]a_{n}[/tex] = 6n - 4
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence, that is
8 - 2 = 14 - 8 = 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 6 , thus
[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4
Thus the formula representing the sequence is
[tex]a_{n}[/tex] = 6n - 4
If a2> 20, then which of the following could be a value of a?
6 b. 3 c. (-8) d. 2
I'll give brainliest
Answer:
Step-by-step explanation:
a
The square root of 20 = 4.47 so a for sure.
But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list
Now what to do about - 8
(- 8)^2 = 64
The square root of 64 = +/- 8
It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.
I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.
a for sure.
b and c I think so.
-8 is iffy.

Jesse is saving the money he earns in his piggybank. He had already earned
$60 from previous work. He charges $15 to mow one lawn. After mowing 4
lawns, how much total money will he have in his piggybank?
Answer:
Jesse will have $120.
Step-by-step explanation:
First you need to set up your equation. We know Jesse has $60 already and that he charges $15 per lawn. Your equation will look something like this:
15x+60=?
Then you plug in the 4 lawns he did:
15(4)+60=
Then you solve and get 120! :)
PS Parenthesis mean you are multiplying. Same thing as saying
15 x 4 + 60= 120
f(x) = -x2 + 10x - 17 a. Axis of Symmetry: b. Vertex: (Max, Min) c. Domain: d. Range:
Answer:
Below in bold.
Step-by-step explanation:
f(x) = -x^2 + 10x - 17
Convert to vertex form by:
f(x) = -(x^2 - 10x) - 17
= - [(x - 5)^2 - 25] - 17
= -(x - 5)^2 + 25 - 17
= -(x - 5)^2 + 8,
a. So axis of symmetry is x = 5.
b. Vertex is (5, 8) Max.
c. Domain is All real x.
d. Range is (-∞, 8].

someone help me with this answer please!!!
Answer:
C
Step-by-step explanation:
Both AB and AC have the length of 8, meaning that they're congruent.
This means that we have an isosceles triangle.
Angle B and Angle C are equal and all angles in a triangles add up to 180 degrees so:
30 + 30 = 60
180 - 60 = 120
So C would be your answer.
Please let me know if I'm incorrect :)
Answer:
120°
Step-by-step explanation:
This is an Isosceles triangle and that means angle C = angle B
Since the sum of interior angles in a triangle is equal to 180° the measure of angle A is = 120°

Ryan buys 4 tacos for $5 and Maria buys 5 tacos for $8. Did they pay the same rate? Explain and show your reasoning? P.S im in a class right now so yeah.
Answer:
Step-by-step explanation: You must multuply the number of tacos by the money for all of them then you compare them and see if the see if they payed the same rate!P.S i'm in class too!!
Answer: They did not pay the same rate
Step-by-step explanation:
If they were to pay the same price the unit rate would be 1.25 but instead Ryan paid 1.25 for each taco and Maria paid 1.6 for each taco, which means they did not pay the same rate.

What is 108, 200, 000 in scientific notation?
Two parallel lines are crossed by a transversal.
Parallel lines r and s are cut by transversal q. On line s where it intersects with line q, the uppercase left angle is 125 degrees and the bottom right angle is d degrees.
What is the value of d
Answer:
125
Step-by-step explanation:
Measure of d will be,
⇒ d = 125°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Here, r and s are two parallel lines
And, q is the Transversal
Here, Uppercase left angle is 125 degrees
And, The bottom right angle is d degrees
We know that the sum of supplementary angles is 180°
Hence, By the figure, we get;
125 + x = 180
x = 180 - 125
x = 55°
Also we know that
Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs of alternate interior angles. Alternate interior angles are congruent, meaning they have equal measure.
So, Measure of d will also be,
d = 125°
Or,
d = 180 - 55
= 125°

Lin rode her bike 2 miles in 8 minutes. How many miles did she go in 4
minutes?
Answer:
1 mile: 4 minutes
Step-by-step explanation:
This problem can be expressed with a simple ratio: 2:8
Now, thankfully the numbers are even so we just need to simplify the ratio to get our answer. Ratios work like fractions in that manner. So we just need to divide both sides by 2 to get the _:4 result.
This gives us a ratio of 1:4. Therefore, Lin travelled 1 mile in 4 minutes.

I looked up how to do this, but I just dont understand how the internet explains it, I need a step by step simple explanation on how to do it.
Answer:
0
Step-by-step explanation:
To solve this without L'Hopital's rule, you need to use this identity:
lim(x→0) (sin x / x) = 1
lim(x→0) (sin²x / x)
lim(x→0) (sin x / x) (sin x)
lim(x→0) (sin x / x) · lim(x→0) (sin x)
1 · 0
0
Alternatively, since plugging in x=0 gets 0/0, we can use L'Hopital's rule. Replace the numerator and denominator with their derivatives.
lim(x→0) (sin²x / x)
lim(x→0) (2 sin x cos x / 1)
0
