the first and third terms in the following Fibonacci sequence are x and y.
Write down algebraic expressions for the second, fourth and fifths terms.
plz reply ASAP
Answer:
The second term of the sequence is y-xThe fourth term of the sequence is 2y-xThe fifth term of the sequence is 3y-xStep-by-step explanation:
The next term of a Fibonacci sequence is generated by taking the sum of the 2 preceding value of the sequence. Given the the first and third term of a Fibonacci sequence to be x and y
x, _, y...
let the second term be a, fourth term be b and fifth term be c to have the sequence;
x, a, y, b, c...
According to the definition;
x+a = y... 1
a+y = b... 2 and;
y+b = c... 3
From equation 1, a = y-x
Substituting a = y-x into equation 2 to get b we have;
(y-x)+y = b
2y-x = b
b = 2y-x
Substituting b = 2y-x into equation 3 to get 'c'
y + 2y-x = c
3y-x = c
c = 3y-x
The second term of the sequence is y-x
The fourth term of the sequence is 2y-x
The fifth term of the sequence is 3y-x

Two sides of an obtuse triangle measure 10 inches and 15 inches. The length of longest side is unknown. What is the smallest possible whole-number length of the unknown side? 18 inches 19 inches 24 inches 25 inches
Answer:
19 inches is the correct answer.
Step-by-step explanation:
Side 1 = 10 inches
Side 2 = 15 inches
It is given that it is an obtuse angle triangle i.e. the largest angle of the triangle is more than [tex]90^\circ[/tex].
Let us suppose, that the triangle be a right angle triangle, then the largest angle will be [tex]90^\circ[/tex]. The largest side is known as Hypotenuse.
As per pythagoras theorem:
[tex]Hypotenuse^{2} = Base^{2} + Height^{2}[/tex]
[tex]\Rightarrow 10^{2} + 15^{2} = Hypotenuse^2\\\Rightarrow 325 = Hypotenuse^2\\\Rightarrow Hypotenuse = 18.04\ inches[/tex]
So, largest side comes out be 18.04 inches.
But actually, the largest angle is more than [tex]90^\circ[/tex] so the largest side will also be greater than 18.04 inches.
Hence, the answer is:
Smallest possible whole number length of unknown side will be 19 inches.
Answer:

Will give brainliest answer What is the value of a21? A.36 B. 58 C.60 D. 41
Answer:
41
Step-by-step explanation:
Matrix Multiplication follows a row-column format. In order to compute this, you must be familiar with vector dot products.
With that in mind, lets get straight into it.
The order that matrix multiplication follows means that the terms in the result are filled in left to right, then top to bottom.
Therefore, a21 will be the 3 value that is computed. This is important becuase this allows to directly compute a21, instead of using up a lot of time computing all the values before.
As a21 is located in the bottom row 1st column, we take the dot product of the 2nd row in matrix 1 and the 1 column in matrix two.
So we have:
(7 2) dot (5 3) = 7*5 + 2*3 = 41
Lisa has a gym membership at Lifetime Fitness. It costs $29.95 to join and she also pays a monthly charge. Lisa has been a member for 11 months. She has paid a total of $298.90 for her membership. Write an equation that could be used to find, m, the monthly membership fee.
What is the monthly membership fee?
Answer:
298.90 - 29.95 = (ANSWER) divide it by 11 then you will have the monthly cost
Step-by-step explanation:
Answer:
monthly paid= 24.45
Step-by-step explanation:
if we take membership join fee=x=29.95
and the monthly fee=m
so the equation will be
11 m + x =298.90
so by substitute x
m=24.45 $/month

4. In Kendra's school, 28 percent of seven graders went
to a movie theater over the weekend. If there are 800
students in the seventh grade, how many of them saw
a movie?
Answer:
Step-by-step explanation:
1) Let x represent the sale price.
normal price = $39.95. This week they are on sale for 25% off the regular price. The amount taken off is
25/100 × 39.95 = 9.9875
Sale price = 39.95 - 9.9875 = $29.9625
2) number of games played by the tigers is 11 + 4 = 15
Percentage of games won is
11/15 × 100 = 73.3%
number of games played by the cubs is 10 + 3 = 13
Percentage of games won is
10/13 × 100 = 76.9%
3) increase in stock price = 61.5 - 52.63 = $8.87
Percentage increase = 8.87/52.63 × 100 = 16.85%
4) if 28 percent of seven graders went
to a movie theater over the weekend and there are 800 students in the seventh grade, then the number of seven graders that saw
the movie is
28/100 × 800 = 224

Find the radius of a circle that has a circumference of 16.
r = 4
r = 8
r = 12
r = 16
Answer:
r=8
Step-by-step explanation:
Because 16 divided by 2 is 8
The radius of a circle has a circumference of 16 at r = 8.
What is the radius of a circle?Given: the formula for the circumference of a circle is C = 2r, where r is the radius and C is the circumference.
The circumference of a circle is equal to π.
π ≈ 3.14
multiplied by the diameter of the circle.
Therefore, the diameter has twice the length of the radius.
In equation form:
2r = d.
2r = 16.
r = 8.
Note, 2r = d,
Then, the equation C = 2πr holds and can be used in place of C = πd.
The radius of a circle has a circumference of 16 at r = 8.

If A = 3x² + 5x - 6 and B --2x2 - 6x + 7, then A - B equals?
Answer:
x^2 + 11x - 13
Step-by-step explanation:
A = 3x^2 + 5x - 6
B = 2x^2 - 6x + 7
=> A - B = (3x^2 + 5x - 6) - (2x^2 - 6x + 7)
= (3x^2 - 2x^2) + (5x + 6x) - (6 + 7)
= x^2 + 11x - 13

A figure is a regular n-gon. Which of the following
expressions represents the sum of the measures of
the exterior angles of the polygon, one at each
vertex?
A. (180 - 10°
360
B. 180
12
C. (n - 2)180°
D. 360°
Answer:
The correct answer is D. 360°
Step-by-step explanation:
The sum of all the exterior angles of a regular n-gon or a polygon is always equal to 360°.
Let us consider the image attached.
First of all let us consider the triangle.
As per the property of exterior angles: The exterior angle is equal to the sum of 2 opposite interior angles.
[tex]\Rightarrow \angle 1=\angle B + \angle C\\\Rightarrow \angle 2=\angle A + \angle C\\\Rightarrow \angle 3=\angle A + \angle B[/tex]
Where [tex]\angle A, \angle B\ and\ \angle C[/tex] are the interior angles of the triangle.
Adding the above equations:
[tex]\angle 1 +\angle 2 +\angle 3 = 2 \times (\angle A +\angle B +\angle C )[/tex]
The sum of interior angles of a triangle is always equal to 180°
[tex]\angle A +\angle B +\angle C = 180^\circ[/tex]
[tex]\angle 1 +\angle 2 +\angle 3 = 2 \times 180^\circ\\\Rightarrow \angle 1 +\angle 2 +\angle 3 = 360^\circ[/tex]
Hence, proved that the sum of exterior angles is [tex]360^\circ[/tex].
So, the correct answer is D. [tex]360^\circ[/tex]
