Answer:
a) 10 ; scale factor is 2
b) 15; scale factor 5
c) 1.5; scale factor is ½ or 0.5
d) 6.3; scale factor is 3
e) 24, 2; scale factor is ⅛ 0.125
f) 4.6, 9; scale factor 3⅕ or 3.2
Step-by-step explanation:
a) to get form your first term to the corepnoding term you have to divide the first term form your second term for example 6÷3 is 2 so 2 is the scale factor. You multiply 5 by 2 so 5×2 is 10 the blank is 10
b,d and f) Do the same step process like what you do for letter a to get these terms
c and e) Do the same steps as a but keep in mind that because the number in the second term are smaller the scale factor is less then 1 so for c it would be ½ as opposed to 2 since the new number is smaller

Find the nth term of this quadratic sequence
3, 11, 25, 45, .
The term of the given quadratic sequence is found to be 3n² - n + 1 using the principle of mathematical induction.
Given,
In the question:
The quadratic sequence is :
3, 11, 25, 45, ...
To find the nth term of the quadratic sequence.
Now, According to the question;
The first term of the sequence is 3, the second term is 11, the third term is 25, and the fourth term is 45.
The difference between the first and second terms can be calculated as follows:
11-3 = 8
The difference between the second and third terms can be calculated as follows:
25-11 = 14
The difference between the third and fourth terms can be calculated as follows:
45-25 = 20
The sequence is expressed as follows:
3,3+8,11+11,25+20,...
The difference between consecutive terms expands by 6.
Use the principle of mathematical induction.
6[tex](\frac{n(n+1)}{2} )[/tex]
= 3n(n+1)
The sequence's nth term can be calculated as follows:
term = 3n(n+1) - 4n + 1
= 3n² - n + 1
Hence, the term of the given quadratic sequence is found to be 3n² - n + 1 using the principle of mathematical induction.

QR is a midsegment of triangle BCD. Solve for the value of x.
The value of x when QR is a midsegment of triangle BCD is 11 units.
According to the question,
We have the following information:
QR is a midsegment of triangle BCD.
Now, we know that the length of midsegment of any triangle is equal to half of the length of side corresponding to the midsegment.
So, we have the following expression:
QR = BD/2
Putting the values of QR and BD from the figure:
x-2 = (x+7)/2
Using the cross multiplication method:
2x-4 = x+7
Moving x from the right hand side to the left hand side:
2x-x = 7+4
x = 11 units
Hence, the value of x when QR is a midsegment of triangle BCD is 11 units.

g suppose the eigenvalues are real, distinct, and non-zero. [i] if both eigenvalues were positive, how would the equilibrium at (0, 0) be classified?
As previously stated, a system will not be stable if its eigenvalues have any non-negative real parts, the system will be unstable if an eigenvalue has no imaginary part and is equal to zero. A trivial instance of the complex eigenvalue with a zero component exists here.
When both eigenvalues are zero, what takes place?
A zero eigenvalue implies the network being referred to is particular.The null space of the matrix is based on the eigenvectors that correspond to the zero eigenvalues.

which constants can be multiplied by the equations so one variable will be eliminated when the systems are added together? 5x 13y
The constants that we have to multiply to eliminate one variable from the system are 12 and 5.
The equations are
5x+13y = 232
12x + 7y = 218
Here we can cancel both x term and y terms, lets choose x terms and apply the elimination method
The coefficient of x in first equation is 5 and 12 in second equation
We have to make it same
Prime factorization
5 = 5×1
12 = 2×2×3
LCM (5, 12 ) = 2×2×3×5 = 60
Multiply the first equation by 12 and second equation by 5
60x + 156y = 2784
60x + 35y = 1090
Subtract equation 2 from equation 1

Ratio is always written as x/y where y can never be zero.
Grams of flour needed for every 200200200 and grams of sugar = 300300300 grams
The equation that represents how many grams of flour we need for some grams of sugar is fff = 222/333
Let’s assume fff as grams of flour and sss as grams of sugar.
So, the ratio for grams of flour:grams of sugar will be,
