My number has a tens digit that is 8 more than the ones digit. Zero is not one of my digits. Write the 2-digit number that match
es the clues
2 answers:
The requested number is: <u><em>91 </em></u>
<h3>Further explanation </h3>Numbers are quantities used in measurements
Numbers in mathematics can be divided into several terms
- 1. integer
numbers consist of positive, negative and 0 numbers
- 2. natural numbers
numbers consisting of positive numbers, starting with number 1
- 3. whole number
a number consists of positive numbers and zeros
- 4. prime number
numbers that can only be divided by numbers themselves and the number 1
And examples of other numbers such as imaginary numbers, real numbers, rational numbers, etc.
Integers themselves consist of
- 1. positive integers
the number to the right of the number 0 is 1,2,3 ...
- 2. negative integers
the numbers to the left of the zeros are -1, -2, -3 ...
- 3. number 0
From the above questions we can separate into several sections:
- Write the 2-digit number that matches the clues
Means the number requested consists of 2 numbers, let us suppose the tens = x and the ones = y, so the number is<em><u> </u></em><em><u>xy </u></em>
- My number has a tens digit that is 8 more than the ones digit
we can translate this sentence into the equation:
x = y + 8
So from the numbers 0 to 9 that have a difference of 8 to fill the values of x and y are
- 0 and 8
- 1 and 9
because Zero is not one of my digits, the most appropriate numbers x and y are <u>1 and 9 </u>
So the number requested is

Answer:
a) The new triangle is a reflection of the original across the origin. All angles, segment lengths, and line slopes have been preserved: the transformed triangle is congruent with the original.
b) The new triangle is a reflection of the original across the origin and a dilation by a factor of 2. Angles have been preserved: the transformed triangle is similar to the original. The transformation is NOT rigid.
Step-by-step explanation:
1. The transformed triangle is blue in the attachment. It is congruent with the original. The transformation is "rigid," a reflection across the origin. All angles and lengths have been preserved, as well as line slopes.
__
2. The transformed triangle is orange in the attachment. It is similar to the original, in that angles have been preserved and lengths are proportional. It is a reflection across the origin and a dilation by a factor of 2. Line slopes have also been preserved. A dilation is NOT a "rigid" transformation.
Let
Differentiating twice gives
When x = 0, we observe that y(0) = a₀ and y'(0) = a₁ can act as initial conditions.
Substitute these into the given differential equation:
Then the coefficients in the power series solution are governed by the recurrence relation,
Since the n-th coefficient depends on the (n - 2)-th coefficient, we split n into two cases.
• If n is even, then n = 2k for some integer k ≥ 0. Then
It should be easy enough to see that
• If n is odd, then n = 2k + 1 for some k ≥ 0. Then
so that
So, the overall series solution is
