Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given y = 5(x + 1) = 5x + 5 ← in slope- intercept form
with slope m = 5
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{5}[/tex], thus
y = - [tex]\frac{1}{5}[/tex] x + c ← is the partial equation of the perpendicular line
To find c substitute (10, 2) into the partial equation
2 = - 2 + c ⇒ c = - 2 + 2 = 4
y = - [tex]\frac{1}{5}[/tex] x + 4 ← in slope intercept form
Multiply all terms by 5
5y = - x + 20 ( add x to both sides )
x + 5y = 20 ← in standard form → D
Anja represents the inequality
Answers
Based on the phrase they gave, the inequality would look like this:
[tex]\frac{4-g}{8} >-15[/tex]
[tex]\frac{4-g}{8}\leq-15[/tex]
the quotient(÷) of [the difference(- subtraction) of 4 and a number(g) and 8] is at MOST -15.
since the sign is ≤, this means that the inequality is less than or equal to -15, so -15 is the maximum number for the inequality.

EXPLANATION
The given expression is
[tex] \sqrt[5]{4} \times \sqrt{2} [/tex]
Recall that:
[tex] \sqrt[n]{ {a}^{m} } = {a}^{ \frac{m}{n} } [/tex]
[tex]\sqrt[5]{ {2}^{2} } \times \sqrt{ {2}^{1} } [/tex]
[tex]\sqrt[5]{ {2}^{2} } \times \sqrt{ {2}^{1} } = {2}^{ \frac{2}{5} } \times {2}^{ \frac{1}{2} } [/tex]
Recall that:
[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]
We now apply this property of a exponents to obtain:
[tex]\sqrt[5]{ {2}^{2} } \times \sqrt{2} = {2}^{ \frac{2}{5} + \frac{1}{2} } = {2}^{ \frac{9}{10} } [/tex]

The graph of y = 1 x is vertically stretched by a factor of 3, reflected across the y-axis and shifted to the left by 2 units. What is the function of the resulting graph? A) y = 3 x − 2 B) y = −3 x + 2 C) y = 1 3x − 6 D) y = −1
Answers
y = 3(-x - 2)
Any horizontal transformations or reflections you make to y = x must be within the parentheses.
The transformed function is g(x) = -7 [tex]log_6[/tex] (-x) +2
The given base function is
f(x) = [tex]log_6[/tex] (x)
Then we have to find the transformed function.
First of all, the graph of the base function f(x) = [tex]log_6[/tex] (x) is vertically stretched by a factor of 7, then the newly transformed function becomes y = 7[tex]log_6[/tex](x)
Then the graph of y = 7[tex]log_6[/tex](x) is reflected over the x-axis, then the newly transformed function becomes y = -7log6(x)
Then the graph of y = -7[tex]log_6[/tex](x) is reflected over the y-axis, then the newly transformed function becomes y = -7[tex]log_6[/tex](-x)
And finally, the graph of y=7log6(-x) is vertically shifted up by 2 units, then the newly transformed function becomes
y = -7 [tex]log_6[/tex] (-x) +2
which is the required equation for the transformed function.

In an examination, 15% candidates failed in science and 20% in Mathematics. If 10% failed in both the subjects, find percentage of those who passed in both the subjects.
Answers
To determine the percentage of students who passed both exams, we first calculate the percentage of students who failed in either subject, then subtract that from 100%. Given that 15% failed in Science, 20% in Mathematics, and that 10% failed in both, we find that 75% of students passed both courses.
Explanation:In this question, we have to find out the percentage of the candidates that passed in both subjects, Science and Mathematics. The percentages given show the failure rates in Science, Mathematics, and in both. Here, we need to use the concept of sets where we sum the individual percentages and subtract the intersection. It is defined as P(A U B) = P(A) + P(B) - P(A ∩ B).
According to the problem, 15% failed in Science and 20% in Mathematics. So, the candidates failing in any one of the subjects would be 15% + 20% = 35%. However, those who failed in both subjects (i.e., intersection part) is 10%, and double-counted when we added up the individual percentages. Therefore, we subtract this from our earlier total, giving us 35% - 10% = 25%. This implies that 25% of candidates fail in at least one subject.
As for those who pass in both, since we know that the total should be 100%, and we've figured out that 25% failed in at least one subject, thus, those who passed should be the remaining 75%.

The percentage of those who passed in both the subjects is equal to 85%.
How to determine the percentage of those who passed in both the subjects?In order to determine the percentage of those who passed in both the subjects, we can use the principle of inclusion and exclusion;
Let the variable A represent the percentage of candidates who failed in Science, which is 15%.Let the variable B represent the percentage of candidates who failed in Mathematics, which is 20%.Let the variable C represent the percentage of candidates who failed in both Science and Mathematics, which is 10%.Let the variable P represent the percentage of candidates who passed in both Science and Mathematics.Based on the principle of inclusion and exclusion, we have:
Total percentage of candidates who failed in either Science or Mathematics = A + B - C
Percentage of candidates who passed in both subjects = 100% - (A + B - C)
Percentage of candidates who passed in both subjects = 100% - (15% + 20% - 10%)
Percentage of candidates who passed in both subjects = 100% - 15%
Percentage of candidates who passed in both subjects = 85%.

Three roots of a fifth degree polynomial function f(x) are -2,2 and 4 + i which statement describes the number and nature of all roots for this function?
Answers
Answer:
f(x) has three real roots and two imaginary roots.
Step-by-step explanation:
Given that three roots of a fifth degree polynomial function f(x) are -2,2 and (4+i).
Now we need to find about which of the given statements describes the number and nature of all roots for this function.
We know that imaginary roots always occur in conjugate pairs.
So if (4+i) is root then (4-i) must also be the root.
So now we have total 4 roots
-2, 2, (4+i) and (4-i).
Degree of the polynomial is 5 so that means 1 root is still remaining. It can't be imaginary as that must be in pairs
So that means 5th root is real.
Hence correct choice is :
f(x) has three real roots and two imaginary roots.

The equation y = 4x + 4 describes the relationship between the quantities x and y. Are the quantities in a proportional relationship? A) Yes, because the graph of the equation is a straight line. B) No, because the graph of the equation is not a straight line. C) Yes, because the graph of the equation passes through the origin. D) No, because the graph of the equation does not pass through the origin.
Answers
Answer:
Step-by-step explanation:
The answer is a I am not sure
The relationship described by y = 4x + 4 is not proportional because Option D. the graph does not pass through the origin. The y-intercept is 4, indicating it does not meet the criteria for direct proportionality.
The equation y = 4x + 4 describes a linear relationship between x and y. However, for two quantities to be directly proportional, their relationship must be of the form y = kx, meaning that the graph of their relationship must pass through the origin (0, 0).
In the equation y = 4x + 4, the y-intercept is 4, not 0. Therefore, the graph of this equation does not pass through the origin.
Option D) No, because the graph of the equation does not pass through the origin.

A football team scored a total of 37 points in a game. The team scored some field goals worth 3 points each and some touchdowns with extra points, each together worth 7 points. The team made 19 more points in touchdowns with extra points than in field goals.
Let 'x' be the number of field goals and 'y' be the number of touchdowns. Then the equations are given as,
3x + 7y = 37 ...1
7y = 3x + 19 ...2
From equations 1 and 2, then we have
14y = 56
y = 4
Then the value of 'x' is calculated as,
7(4) = 3x + 19
28 = 3x + 19
3x = 9
x = 3
The number of field goals and touchdowns of the team score will be 3 and 4, respectively.

So if segment QS and segment PR are equal then all parts are equal which means segment QT= segment PT, segment TR= segment TS. segment QS id equal to 12 which means segment PR is equal to 12. You get segment TR by subtracting 4.9 from 12. Now you know that segment TR is 7.1 which means that segment TS is 7.1.
You also know that segment PS is equal to segment QR so you know that segment QR is 9cm because segment PS is 9cm.
m∠QPR is 33° because you know that ΔQPR's sum is 180 and you know that ∠PQR is 114° b/c 44+70 is 144, 180-144=66 now you take 66 and divide it by 2 (for the two angles left) that equals 33.
m∠STR is 92°. You know this by taking the base angle in ΔPTQ and multiplying it by two (which now equals 88, the base angle is 44°) and you take this number and subtract it from 180. 180-88=92. 92 is you measure of angle STR.
A store reduces the price of a jacket by 40%. The sale of the jacket is marked as $30.00.
What percent of the original price is the sale price?
Can someone help me?
Answers
Answer:
60%
Step-by-step explanation:
Sales Price = 100 - 40 = 60%
The sales price is $30.00
Therefore 60% is equal to $30.00
60% = $30
1% = 30 ÷ 60 = $0.50
100% = 5 x 100 = $50
The original price is $50
Percentage of the original price = 30/50 x 100 = 60%
