the tens digit of a 2 digit number is 5 greater than the units digit if you subtract twice the reverse number the result is one fourth the original
Answer:
The original number is 72.
Step-by-step explanation:
Let the number by
[A][B]
The reverse number is
[B][A]
Original number:
A = B + 5
[A][B] - 2[B][A] = [A][B]/4
10A + B - 20B - 2A = (10A + B)/4
8A - 19B = (10A + B)/4
32A - 76B = 10A + B
22A - 77B = 0
22(B + 5) - 77B = 0
22B + 110 - 77B = 0
-55B = -110
B = 2
A = B + 5 = 2 + 5 = 7
The original number is 72.
The reverse is 27.
Let's check.
"the tens digit of a 2 digit number is 5 greater than the units digit"
7 is 5 greater than 2,so 72 looks good so far.
"if you subtract twice the reverse number the result is one fourth the original"
The reverse number is 27. Twice 27 is 2 × 27 = 54.
Subtract 54 from 72: 72 - 54 = 18
18 is 1/4 of 72. It works.
Answer: the original number is 72

How many and of which kind of roots does the equation f(x)=x^3+2x^2+4x+8 have?
The cubic equation f(x) = x³ + 2 · x² + 4 · x + 8 has one real root and two complex roots.
What kind of roots does have a cubic equation?
In this problem we have a cubic equation and the nature of their roots must be inferred according to a algebraic method.
Cubic equations are polynomials of the form y = a · x³ + b · x² + c · x + d, there is a method to infer the nature of the roots of such polynomials: The discriminant from Cardano's method, an analytical method used to solve polynomials of the form a · x³ + b · x² + c · x + d = 0.
The discriminant is described below:
Δ = 18 · a · b · c · d - 4 · b³ · d + b² · c² - 4 · a · c³ - 27 · a² · d² (1)
Where:
There are three distinct real roots for Δ > 0.Real roots with multiplicity greater than 1 for Δ = 0.A real root and two complex roots for Δ < 0.If we know that a = 1, b = 2, c = 4 and d = 8, then the nature of the roots is:
Δ = 18 · 1 · 2 · 4 · 8 - 4 · 2³ · 8 + 2² · 4² - 4 · 1 · 4³ - 27 · 1² · 8²
Δ = - 1024

C. They have the same end behavior as x approaches -∞ and the same end behavior as x approaches ∞. D. They have the same end behavior as x approaches -∞ but different end behavior as x approaches ∞.
The answer choice which correctly draws a comparison between the end behaviours of the functions is; Choice C; They have the same end behavior as x approaches -∞ and same end behavior as x approaches ∞.
Which answer choice correctly compares the end behaviour of the functions?As given in the task content; the graph of the exponential function passes through (-4, 9), (0, 1), (1, 0), and (5, -2).
It therefore follows that as; x reduces (approaches -∞), the y value increases.
And, as x -increases (approaches +∞), the y-value decreases.
For the table, the values can be written as coordinates as follows; (-1,2), (0,4), (1,6), (2, 0), (3,-2).
Consequently, as x reduces (approaches -∞), the y- values decrease.
And, as x increases (approaches +∞), the y-values decrease.

List the domain and range in interval notation for the following graphs listed?
The domain and range of the given graphs are as follows,
(b) Domain: x ∈ (-∞, ∞), Range: y ∈ (-∞, ∞)
(c) Domain: x ∈ [-2, ∞), Range: y ∈ [1, ∞)
Determining the Domain and Range from a Graph
The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The various output values are represented on the y-axis as the range.
Thus, in graph (b),
Since the values of the given curve extends infinitely (denoted by arrowhead of the curve) on positive as well as negative sides for both the axes, x and y, its domain and range both are (-∞, ∞).
Similarly, in graph (c),
The minimum value on x-axis or abscissa is -2 and maximum is infinity. Hence, its domain is [-2, ∞). The minimum ordinate value or y-coordinate is 1 and maximum is infinity. Thus, its range is [1, ∞).

if a set of test scores has a large range but a small standard deviation, describe what this means about students' performance on the test.
a. Most of students' test scores are around the mean, except that few students got scores much less than the mean.
b. Most of students' test scores are around the mean.
c. Most of students' test scores are around the mean, except for the students who got scores much greater than the mean and a few students who got scores much less than the mean.
d. Most of students' test scores are around the mean, except for the students who got scores much greater than the mean.
Answer:
C
Step-by-step explanation:
Option b accurately reflects this scenario, as it states that most of the students' test scores are around the mean, which aligns with the idea of a small standard deviation.
The correct option is:
b. Most of students' test scores are around the mean.
A large range indicates that there is a significant difference between the highest and lowest scores in the set.
On the other hand, a small standard deviation indicates that the data points (test scores) are clustered closely around the mean.
When the range is large but the standard deviation is small, it means that most of the students' test scores are relatively close to the mean, and there are no extreme values that are significantly far from the mean. In other words, the majority of students performed similarly on the test, with only a few outliers having scores much higher or much lower than the mean.
Option b accurately reflects this scenario, as it states that most of the students' test scores are around the mean, which aligns with the idea of a small standard deviation.

Find the area and perimeter
for each polygon.
Answer:
5. P = 23 m
A = 15 [tex]m^{2}[/tex]
6. P = 24.4 in
A = 15.3 [tex]in^{2}[/tex]
Step-by-step explanation:
Area formula of a triangle is A = 1/2 bh
Area formula of a parallelogram is A = bh
5. The height of a triangle is perpendicular to the base.
A = 1/2 * 10 * 3
A = 15 [tex]m^{2}[/tex]
6. The height of the parallelogram is also perpendicular to the base.
A = 9 * 1.7
A = 15.3 [tex]in^{2}[/tex]
Perimeter means you add all the side lengths.
5. The side lengths are 5m, 8m, and 10m. Adding those together, you get 23m.
6. A parallelogram has congruent opposite sides. That means your side lengths are 9 in, 3.2 in, 9 in and 3.2 in. Adding those together, you get 24.4 in.

The section of paper shown in the pattern below is of a circle. It will be wrapped around a cone. The wrapper will then be painted.
What is the amount of paint needed to paint 100 of these wrappers? Round your answer to the nearest hundred.

Area of a 1/4 sector of a circle = 1/4 * pi r^2
Givens
100 of these quarter sectors
pi = 3.14
r = 12
Solution
You are using area because you are going to paint each one of the sectors. You must cover every cm^2 with paint.
Area = 1/4 * 3.14 * r * r
Area = 1/4 * 3.14 * 12 * 12
Area = 113.25
But there are 100 of them. so the area is

What is the next number in the following sequence 0 0 1 2 2 4 3 6 4 8 5
Answer:
10
Step-by-step explanation:
the sequence follows the rule of adding the number and then the number -1 depending on the number before it. for example, you can see in order to get from 2 to 2, it adds 0 or subtracts by 0. After that to get from 2 to 4, you add 2. After that, you subtract 1 from 2 and you subtract that number which is 1 from 4 to get 3 and so on. Following that rule, you get 10 as the next number in the sequence
ONE HUNDRED LOTTERY TICKETS ARE SOLD FOR $5.00 EACH. ONE PRIZE OF $300
WILL BE AWARDED. STEVE PURCHASES ONE TICKET. FIND HIS EXPECTATION. SHOW ME THE WORK SO I CAN UNDERSTAND THANKS
Steve's expected win from the lottery ticket purchase is $3 because his chance of winning the $300 prize is only 1%.
How are the expected winnings of the lottery determined?The expected winnings for Steve are a function of the probability of some predictable outcomes.
In this situation, the predictable outcome is the size of the lottery prize.
The probability that Steve will win the prize is 1% (1/100), depicting his chance of winning.
Data and Calculations:Sale price per ticket = $5
Lottery prize = $300
Value of lottery prize to Steve if he wins = $295 ($300 - $5)
Probability of winning = 1% (1/100 x 100)
Expected win = $3 ($300 x 1%)
Thus, Steve's expected win is $3, which outweighs the cost of a ticket.

Using Pythagoras Theorem,
=> Hypotenuse^2 = Base^2 + Altitude^2
(15)^2 = (12)^2 + x^2
