2nd term: 3(2)^2 - 1
5th term: 3(5)^2 - 1
Answer:
11 and 74
Step-by-step explanation:
To find the second and fifth terms substitute n = 2, n = 5 into the rule, that is
a₂ = 3(2)² - 1 = 3(4) - 1 = 12 - 1 = 11
a₅ = 3(5)² - 1 = 3(25) - 1 = 75 - 1 = 74
-5y/2=-14/15 how do I solve for y ?
Answer:
Exact form: 28/75
decimal form: 0.373..
Step-by-step explanation:
Answer:
y=28/75
Step-by-step explanation:
You cross multiply
-5y -14
2 = 15
that equals to -75y=-28 you divide both sides by -75 to get rid of it on the left side making the answer
y=28/75

In the diagram, ∠AOB and ∠COB form a linear pair. Which statement must be true about the angles?
A. ∠AOB and ∠COB are supplementary to each other.
B. ∠AOB and ∠COB are supplementary to the same angle.
C. ∠AOB and ∠COB are complementary to each other.
D. ∠AOB and ∠COB are complementary to the same angle.
Please give me a serious answer, and if you don't know what to answer then don't, please.
Answer:
[tex]{{\underline{\textsf{\textbf{A. ∠AOB and ∠COB are supplementary to each other. }}}}}[/tex]
Step-by-step explanation:
As in the question given that, ∠AOB and ∠COB are linear pair and being theses angles are supplements it will form 180°. Hence, option A is the correct ✔️
∠AOB and ∠COB forms a linear pair
∠AOB and ∠COB are supplementary to each other
Given :
In the diagram, ∠AOB and ∠COB form a linear pair.
∠AOB and ∠COB forms a straight line . the sum of angles in a straight line is 180 degrees.
When the sum of angles is equal to 180 degree then they are called as supplementary angles.
∠AOB and ∠COB form a linear pair.
[tex]<AOB +<COB =180[/tex]
the sum of both the angles are equal to 180 degrees .
So, ∠AOB and ∠COB are supplementary to each other.

what is the following quotient
Answer:
Rationalize the denominator by multiplying by the conjugate of (1 + √3), namely (1 - √3). this gives us
(1 - √3) / (1 - 3) or (1 - √3) / -2, which can be rewritten as
(-1 + √3)/2, the last answer choice.

Jayvyn Green Each school year, the seventh graders who study Life Science participate in a special field trip to the city zoo. In 2010, the school paid $1,260 for 84 students to enter the zoo. In 2011, the school paid $1,050 for 70 students to enter the zoo. In 2012, the school paid $1,395 for 93 students to enter the zoo. How many students would enter the zoo if the school paid $1,425?*
Answer:
95 students
Step-by-step explanation:
1260/84 = 15
1,050/70 = 15
1,395/93 = 15
So, it's 15 dollars for every student,
1,425/15 = 95
Check: 1,425/95 = 15

Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek. If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?
Answer:
Eric's father works for 5 hours in the afternoon
Step-by-step explanation:
Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek.
Step 1
The number of hours he works each days is calculated as:
40 hours÷ 5days
= 8 hours per day.
Hence, he works 8 hours per day.
Step 2
We are told in the question that:
If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?
The total number of hours in works in a day = Number of hours worked in the morning + Number of hours worked in the afternoon
Hence:
8 hours = 3 hours + x
x = 8 hours - 3 hours
x = 5 hours
Therefore, Eric's father works for 5 hours in the afternoon

When you subtract a number, you get the same result as when you add the opposite of that number. Why?
Step-by-step explanation:
Well, the opposite of a number is the same number with the opposite sign. For example, the opposite of -1 is 1.
So, say we have an equation where we're subtracting a number, for example, 2-1, which obviously equals 1. Now, if we add the opposite of 1 to 2, we get the equation 2+(-1) which still equals 1.
I hope this helps!

4 consecutive integers have a sum of 22. What is the least of the 4 integers?
Answer:
The least of the four integers is 4.
Step-by-step explanation:
Let x be the first integer.
x + (x + 1) + (x +2) + (x + 3) = 22
4x + 6 = 22
4x = 16
x = 4
4 + 5 + 6 + 7 = 22

Answer:
3 = 21 degrees
5 = 21 degrees
1 = 60 degrees
2 = 39 degrees
4 = 39 degrees
Step-by-step explanation:
This problem is really quite easy once you break it down. I assume you want an answer based on the attachment. If a triangle is Isosceles, then its bottom two angles are congruent, so angle 3 = angle 5.
Then, 138 degrees + x * 2 = 180 degrees.
x * 2 = 42 degrees
x = 21 degrees
So 3 and 5 are each 21 degrees
If a triangle is equilateral, then it is also equiangular, meaning each of its angles are equal to each other, and they are each 60 degrees. Then, we know angle 1 is 60 degrees. For 2 and 4, we want to take the measure of the combination of 2 and 3 (the full 60 degrees), and subtract it by the measure of angle 3 to get the measure of angle 2. 60 - 21 = 39 degrees. Angle 2 is 39 degrees. The same can be done with angle 5 and 4 because they are the same measurements.
