For a certain arithmetic sequence, [tex]a_{3} =14, a_{10}=98[/tex]. Write the first three terms of the sequence.
I'll mark you as brainliest *only if you answer*. Thanks <3
Answer:
An arithmetic sequence is defined by:
[tex]a_n = a_{n-1} + d[/tex]
Here, we know that:
[tex]a_3 = 14\\a_{10} = 98[/tex]
Using the recursive relation, we can write:
[tex]a_{10} = 98 = a_9 + d[/tex]
And can keep applying the recursive relation, so we will have:
[tex]98 = a_9 + d = (a_8 + d) + d = a_8 + 2*d[/tex]
And so on, until we get to a known term:
[tex]98 = a_8 + 2*d = a_7 + 3*d = a_6 + 4*d = a_5 + 5*d = a_4 + 6*d = a_3 + 7*d[/tex]
[tex]98 = a_3 + 7*d = 14 + 7*d[/tex]
Then we can solve:
98 = 14 + 7*d
for d:
98 - 14 = 7*d
84 = 7*d
84/7 = d = 12
Now we know the value of d, we can keep using the recursive relation to find the first 3 terms:
Here, we can rewrite the recursive relation as:
[tex]a_{n-1} = a_n - d[/tex]
Then:
[tex]a_2 = a_3 - d = 14 - 12 = 2\\a_2 = 2[/tex]
[tex]a_1 = a_2 - d = 2 - 12 = -10\\a_1 = -10[/tex]
[tex]a_0 = a_1 - d = -10 - 12 = -22\\a_0 = -22[/tex]
Then the first 3 terms are:
-22, -10, 2

a²+b²+c²=138 and ab +bc+ca=3, Find a+b+c
[tex]a ^{2} + b {}^{2} + c { = 138} and \: ab + bc + ca \: find \: a + b + c[/tex]
ans pls?
Answer:
a + b + c = 12
Step-by-step explanation:
The given information are;
a² + b² + c² = 138
a·b + b·c + c·a = 3
The required data = a + b + c
Using an online tool, we have;
(a + b + c)² = (a + b + c) × (a + b + c) = 2·a·b + 2·b·c + 2·c·a + a² + b² + c²
∴ (a + b + c)² = 2·(a·b + b·c + c·a) + (a² + b² + c²)
Where;
a·b + b·c + c·a = 3, and a² + b² + c² = 138, we have;
(a + b + c)² = 2 × 3 + 138 = 144
(a + b + c)² = 144
(a + b + c) = √144 = 12
a + b + c = 12.
Which expression is equivalent to this expression?

Answer:
6^10
Step-by-step explanation:
6^2 * 6^11
-----------------
6^3
First simplify the numerator. We know a^b*a^c = a^(b+c)
6^(2+11)
-----------------
6^3
6^(13)
-----------------
6^3
Then a^b / a^c = a^(b-c)
6^(13-3) = 6^10
Answer:
6^10
Step-by-step explanation:
To solve this you need to remember 2 things.
First off, multipication is addition with exponents.
And secondly, division is subtraction with expoinents.
So on the top we have 6^2*6^11
So this is really 6^11+2
=
6^13
Now we need to divide by 6^3:
6^13/6^3
And this would tecnically be:
6^13-3
=
6^10
So the expression 6^10 is your answer.
Hope this helps!
What is the equation of a circle with a center (7, -3) and radius 4?
Answer:
see screenshot
general formula is
r² = (x - x-center)² + (y - y-center)²
Find the degree of the polynomial function y=(x-5)(x+5)
Answer:
Step-by-step explanation:
y = (x + 5)(x - 5)
= x² - 5²

At a meeting attended by 23people, the females were 7 more than the males. How many males were there?
Answer:
8
Step-by-step explanation:
x+x+7=23
2x=16
x=8
There were 8 males in the meeting.
How many males were there?Let us assume,
The number of males = x
Number of females = 7+x
Total people = 23
x + x+ 7= 23
2x + 7 =23
2x = 23 - 7
2x = 16
x= 8
There were 8 males in the meeting.

Jackson elementary will have 320 first grade students next year, each class can have 16 students using the equation 16x= 320 , how many first grade classes will the school need?
Answer:
20
Step-by-step explanation:
320 = 16x
Our objective here is to isolate the variable (x) using inverse operations
First we want to get rid of 16
16x is the same as 16 times x( which is multiplication)
The inverse of multiplication is division so to get rid of the 16 we divide by 16 ( but note: whatever you do to one side you must do to the other ) so we divide both sides by 16
320/16=20
16x/16 = x
We would be left with x = 20
This meaning that they would need 20 first grade classes
Answer:
The school will need 20 first grade classes
Step-by-step explanation:
So think about it. There are 320 first grade students and each class can have 16 students which represents the equation 16x=320
All you need to do is solve the equation 16x=320
The equation is multplication. To undo multiplication you need to do division
So, x=320/16
x=20
So overall, your awnser is 20.
Please help!! Find the scale factor dilation
Answer:
2
Step-by-step explanation:
take any point
i am taking F
coordinate of F is (5 , 3)
F' is (10,6)
so use formula
(x , y) = (kx , ky)
(5 , 3) = (5k , 3k) = (10 , 6)
compare corresponding elements
5k = 10
k = 10/5
k = 2
3k = 6
k = 6/3
k = 2
note here k means scale factor
Use p = 2 and p = 8 to determine if the two expressions are equivalent. 4(2 + p) 14 + p Complete the statements.
Answer:
The expressions are not equivalent.
Step-by-step explanation:
Here we have two expressions:
4*(2 + p)
14 + p
We want to evaluate these two expressions in two different values of p to check if the expressions are equivalent or not.
First, we evaluate both of them in p = 2, this is just replace p by 2 in each expression and then solve it.
4*(2 + 2) = 4*4 = 16
14 + 2 = 16
In this case, we can see that both expressions yield the same number, so we could think that the expressions are equivalent, now let's try with other value of p.
Now let's do it with p = 8
4*(2 + 8) = 4*10 = 40
14 + 8 = 22
Now we can see that the results are different, then we can conclude that the expressions are not equivalent.
Answer:
Use p = 2 and p = 8 to determine if the two expressions are equivalent.
4(2 + p) 14 + p
Complete the statements.
If both expressions have the same value after substituting two different values and simplifying, then they are
✔ equivalent expressions
.
When p = 2, the first expression is
✔ 16
and the second expression is 16.
When p = 8, the first expression is 40 and the second expression is
✔ 22
.
The expressions are
✔ not equivalent

What is the
measure of RK to the
nearest tenth if RQ is
7 in., QL is 24 in., and
LK is 3 in.?
R
Work:
Answer:
25.2 in.
Step-by-step explanation:
Given:
RQ = 7 in.
QL = 24 in.
LK = 3 in.
Required:
Length of diagonal RK
Solution:
Apply the extension of the Pythagorean theorem which is:
d² = x² + y² + z²
Where,
d = RK
x = RQ = 7 in.
y = QL = 24 in.
z = LK = 3 in.
Plug in the values
d² = 7² + 24² + 3²
d² = 634
d = √634
d = 25.1793566 ≈ 25.2 in. (nearest tenth)

Answer:
[tex]x=100\\y=60[/tex]
Step-by-step explanation:
The shape of the figure is quadrilateral, that means overall it will be 360 degrees.....
Angle of straight line to find x:
[tex]x+80=180[/tex]
[tex]x=180-80[/tex]
[tex]x=100[/tex]
Now, both the values of x will be 100
Find the value of y:
[tex]y+100+120+80=360[/tex]
[tex]y+300=360[/tex]
[tex]y=360-300[/tex]
[tex]y=60[/tex]
Therefore, [tex]x=100[/tex] and [tex]y=60[/tex]

B. 55 in.2
C. 60 in.2
D. 42 in 2
Correct answer will get 50 points Please answer ASAP!!
Answer:
55 sq. in.
Step-by-step explanation:
Area of figure
= area of triangle + area of rectangle
height of triangle = 6 in.
base of triangle = 6/(sqrt(3)/3) = 18/sqrt(3)
Area of triangle = 6*18/sqrt(3) /2 = 54/sqrt(3) = 31.18 sq. in.
Area of rectangle = 6 * 4 = 24 sq. in
Area of figure = 31.18+24 = 55.18 sq. in

1. Write down the 3D shape each net make.

Step-by-step explanation:
D) Has a five sided shape as a base so its a pentagon-based pyramid
E)Two pentagons and retangular sides Pentagonal Prism
F)All sides and bases are rectangular so Rectangular Prism
G) Eight sided base and triangle shaped sides, Octogon-based Cone
Given: ZDEF is a right angle. Using a paragraph proof, prove 41 is acute.
Let G be some point on the diagonal line away from point E.
Angle DEG represents angle 1.
We're given that angle DEF is a right angle which means it's 90 degrees. Angle DEG is some angle smaller than 90 degrees. By definition, that must mean angle 1 is acute. Any acute angle is smaller than 90 degrees. There's not much else to say other than this is just a definition problem.
----------------
Extra side notes:
If angle 1 was a right angle, then that would mean angle GEF would have to be 0 degrees; however the diagram shows this isn't the case.
If angle 1 was obtuse, then there's no way we'd be able to fit it into angle DEF. In other words, there's no way to have an angle larger than 90 fit in a 90 degree angle.
