If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence. The constant difference in all pairs of consecutive or successive numbers in a sequence is called the common difference, denoted by the letter d.

17. The cost (in dollars) of making n birthday cakes is represented by
C = 24n + 35
How many birthday cakes are made when the cost is $395?
Answer:
the fist one = 160 - 24
the second one = 12.50 / 5
Step-by-step explanation:
Answer:
15. equation: g+24=160, and the answer is g=136
16. equation: 5d=12.50, answer is d=3.5 hours
17. 15 cakes are made when the cost is $395
Step-by-step explanation:
15: You know that there are 160 students in 7th grade. This would be on one side of the equal sign. You know that there are 24 more students in the 7th grade class than the 8th grade class. And we know that g represents the number of students in the 8th grade class. So you set up your equation as g+24=160. You would subtract 24 from both sides: g+24-24=160-24, which gives you g=136.
16: You spend $5 an hour, so, on one side, you will have 5. On the other you will have $12.50. We will let d represent dollars, and it will go with the 5 to give us 5d. The equation is 5d=12.50. From there, you will divide 5 from both sides: 5d/5=12.50/5, which gives you d=3.5.
17: So, we have the equation, and we just plug in what we know. So, $395=24n+35. From there, we will subtract 35 from both sides. That would give us $395=24n and we will divide 24 from both sides to give us n=15 cakes.
Write the equation in point-slope form of the line that passes through the points (4, 7) and (5, 1). Use the first point to write the equation.
Answer:
Step-by-step explanation:
Answer:
[tex]y-7=-6(x-1)[/tex]
Step-by-step explanation:
So first you need to find the slope of the line. You do this by doing [tex]m=\frac{y^{2}-y^{1}}{x^{1}-x^{2}}[/tex]. You would plug the points from the line into the equation to get [tex]m=\frac{1-7}{5-4}[/tex], and when you simplify you would get [tex]m=\frac{-6}{1}[/tex] or [tex]m=-6[/tex]. This means your slope is -6.
Now, point slope form is written as [tex]y-y^{1} = m(x-x^{1} )[/tex] so to write the equation you would plug in the slope and the first point to get [tex]y-7=-6(x-1)[/tex]

What is the sum of the first 11 terms in the arithmetic sequence if the first term is -3 and the common difference d is 5.
a.
152
b.
352
c.
402
d.
242
Answer:
d. 242..................
Answer:
d
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 5, thus
[tex]S_{11}[/tex] = [tex]\frac{11}{2}[/tex] [ (2 × - 3) + (10 × 5) ]
= 5.5(- 6 + 50)
= 5.5 × 44

It is given that the expression [tex]\rm \frac{sin\theta sec\theta}{cos\theta tan\theta}[/tex]
It is required to find the simpler form from the given options.
What is the trigonometric ratio?The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
We have the expression:

We know:
[tex]\rm cos\theta = \frac{1}{sec\theta} \\\\\rm tan\theta = \frac{sin\theta}{cos\theta}[/tex]
By using these trigonometry formulas, we get:
[tex]\rm= \frac{sin\theta sec\theta}{cos\theta tan\theta}\\\\\rm= \frac{sin\theta }{(cos\theta) (cos\theta) \frac{sin\theta }{cos\theta} }\\\\\rm= \frac{1}{cos\theta} \\\\\rm = sec\theta[/tex]
Thus, the simpler form of the expression [tex]\rm \frac{sin\theta sec\theta}{cos\theta tan\theta}[/tex] is [tex]\\\rm sec\theta[/tex].

(CO 3) On the production line the company finds that 85.6% of products are made correctly. You are responsible for quality control and take batches of 30 products from the line and test them. What number of the 30 being incorrectly made would cause you to shut down production?
Answer and explanation:
There should be 85.6% correctly made products
If there is less than 85.6% correctly made products then production would be shut down
therefore 100-85.6= 14.4% of products can be incorrectly made and not more than that
In 30 batches 14.4% =0.144*30=4.32 products
Therefore there must not be more than 4.32 products incorrectly made in a batch of 30 else production is shut down

Start by calculating S40 using the sum of n terms formula
[tex]S_n = \frac n2 * [2a + (n - 1)d][/tex]
So, we have:
[tex]S_{40} = \frac {40}2 * [2*2 + (40 - 1)*2][/tex]
[tex]S_{40} = 1640[/tex]
Calculate S47 using the same formula
[tex]S_{47} = \frac {47}2 * [2*2 + (47 - 1)*2][/tex]
[tex]S_{47} = 2256[/tex]
Subtract S40 from S47
[tex]S_{47} - S_{40} = 2256 - 1640[/tex]

Daniel is currently 26 years older than his son. In six years he will be three times older
than his son. How old are both of them now?
Answer: sorr i onlyknow ti ar
Step-by-step:
Daniel is...remember "is" in a word problem means "equal"
So Daniel=x+26. x representing Daniel's son's age which we do not know.
In six years he will be three times his son's age, "times" meaning multiplication.
Daniel+6=3x, so just equate the two equations. So you must solve;
x+26=3x-6. From there I think you could handle things.
