write the slope intercept form:through: (-2, 3), perp. to x=0
write the slope intercept form:
through: (-2, 3), perp. to x=0
we know that
If the line is perpendicular to x=0 (y-axis), then we have a horizontal line
and the equation of a horizontal line (slope is equal to zero) is
y=3given the function g(x)=3x-7, determine when g(x)=-4
You have the following function:
g(x) = 3x - 7
In order to determine th value of x when g(x) = -4, you equal the previous expression to -4 and solve for x, just as follow:
g(x) = 3x - 7 replace g(x) = -4
-4 = 3x - 7 add 7 both sides
-4 + 7 = 3x simplify
3 = 3x divide by 3 both sides
3/3 = x
x = 1
Hence, the anser is x = 1
A coin is flipped 3 times. What is the probability that it lands on tails exactly 3 times? Write your answer as a reduced fraction (numerator /denominator).
Note the probabilty of getting a tail when a coins is flipped 1 time is 1/2
Now for the probability when flipping a coin 3 times, the probability if the a single flipped is multiplied by itself 3 times..
Therefore, the probability of getting a tail for 3 times is :
[tex]\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}=\frac{1}{8}[/tex]The answer is 1/8
Another solution is to list down the possible outcomes :

A company produces standard size American flags with a measurement of 3’ x 5’. Another company produces mega American flags that are similar to this size. If the shorter side of the mega flag is 48',. What is the length of the longer side?
Solution:
Given:
[tex]\text{Standard size American flag of 3' x 5'}[/tex]Let L be the longer side of the mega flag.
Another company produces a similar flag of 48' x L
Since both flags are similar, then the ratio of the corresponding sides is equal.
Hence,
[tex]\begin{gathered} \frac{3}{5}=\frac{48}{L} \\ \\ \text{Cross multiplying the equation,} \\ 3\times L=5\times48 \\ 3L=240 \\ \\ \text{Dividing both sides by 3,} \\ L=\frac{240}{3} \\ L=80^{\prime} \end{gathered}[/tex]Therefore, the length of the longer side of the mega flag is 80'
An artist paints a mural on a wall at the local park The wall measures 16 1/4 meters in length. The artist paints a star every 18/20 meter. What is the total number of stars the artist paints om the mural?

Is square root of 224 an irrational number ?
ANSWER
YES
EXPLANATION
We want to know if the square root of 224 is an irrational number.
An irrational number is a number that cannot be written as a fraction/ratio of two integers.
If we simplify the square root of 224:
[tex]\begin{gathered} \sqrt{224}\text{ = }\sqrt{16\cdot\text{ 28}}\text{ = 4}\sqrt{28} \\ \text{ }\Rightarrow\text{ 21.166010488}\ldots \end{gathered}[/tex]As we can see, this number cannot be written as a fraction of two numbers.
As a rule, the square root of any number that is not a perfect square is an irrational number.
So, the answer is Yes. It is an irrational number
A spinner with 5 equally sized slices has 2 red slices, 2 yellow slices, and 1 blue slice. Keiko spun the dial 1000 times and got the following results. From Keiko's results, compute the experimental probability of landing on yellow
Probability is expressed as
number of favorable outcomes/number of total outcomes
But probability can also be classified as theoretical probability and experimental probability. The theoretical probability is the normal probability of each outcome while the expreimental probability is the probability of an outcome given that trials have been made.
In this scenario,
total number of trials = 400 + 195 + 405 = 1000
favorable outcomes = number of times that we landed on yellow = 405
the experimental probability of landing on yellow is
405/1000 = 0.405
It rained 3.5 inches in the month of April. It rained 45 less in the month of May. How much did it rain in May?
It rained 1.925 inch in the month of may as the question said "It rained 3.5 inches in the month of April. It rained 45% less in the month of May".
What is inch?In both the British imperial and American customary systems of measurement, the inch serves as a unit of length. It is equivalent to 1/12 of a foot or 1/36 of a yard. The definition of an inch during King Edward II's reign was "three dry, round grains of barley placed end to end lengthwise." The lengths of 12 poppyseeds combined have also been used at various times to define an inch. Since 1959, 2.54 cm has been the official definition of an inch. One inch is exactly equal to 2.54 cm in the metric system, according to the relationship between the two units. The prefix "in" can be used to denote inches. For instance, five feet ten inches could be written as five ft ten in or five feet ten inches.
Here,
45% of 3.5 inch=1.575 inch
Since it rained 45% less than 3.5 inch so,
3.5-1.575=1.975 inch
it rained 1.925 inch in the month of may.
According to the question, it rained 1.925 inches in the month of May "In April, there was 3.5 inches of rain. May saw a 45% decrease in rainfall ".

We must approximate each addition or subtraction, estimating if it is close to 0, 1/2 or 1.
We operate in each case:

Based on the function g(x), the function f(x) is multiplied by a negative number. Hence, there is a reflection across the x-axis.
If it was the "x" variable that was multiplied by a negative number for example, y = e^-x, it would have been reflection across the y-axis.
Since the number multiplied to the function f(x) is not between 0 and 1, we are stretching the function. Hence, the function is vertically stretched by a factor of 4.
Moving to the number -5 that was subtracted from the variable x, we have moved/shifted the function 5 units to the right instead of left.
Lastly, 6 was added to the entire function, therefore, we have translated the functions 6 units up.
To summarize, f(x) = e^x had undergone the following series of transformation: reflection across the x-axis, vertically stretched by a factor of 4, translated 5 units to the right, and translated 6 units up to form g(x).

What is arithmetic progression?Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value. It is also called Arithmetic Sequence.
Given the sequence that represents the diameter of a circle 2.5 cm, 3.1 cm, 3.7 cm and 4.3 cm. this sequence forms an arithmetic progression with a common difference.
nth term of an arithmetic progression is expressed as; [tex]a_{n}[/tex] = a+(n-1)*d
where, a is the first term of the sequence
n is the number of terms
d is the common difference.
Here, the first term a = 2.5 and common difference = 3.1-2.5 = 3.7-3.1 = 4.3-3.7 = 0.6
Substituting the values;
[tex]a_{n}[/tex] = 2.5 + (n-1)*0.6
= 2.5 + 0.6n - 0.6
= 1.9 + 0.6n
Hence, The equation that represents the sequence of diameters is f(n) = 1.9+0.6n

Given that
The two sides of the triangle are 6x and 3x+9 and the two angles are 65 degrees each.
Explanation -
According to the property of the triangle " If the two angles of the triangle are equal then the sides opposite to them will be equal."
Then, we have
AB = BC -------------because angle A = angle B = 65
Substituting their values
6x = 3x + 9
6x - 3x = 9
3x = 9
x = 9/3 = 3
x = 3
So side AB will be,
AB = 6(3) = 18 units.

find the inverse of each function. give any restrictions of the domain [tex]g(x) = - \frac{2}{\times + 2} - 3[/tex]
Answer
The inverse function is
[tex]g^{-1}(x)=\frac{5x}{4}+\frac{25}{4}[/tex]The domain of this inverse function is all real numbers.
Explanation
The question asks us to find the invers of the given function and give any restrictions of the domain if that exists.
The function is
g(x) = -5 + (4x/5)
To obtain the inverse of a function, the right approach is to write g(x) as y, then make x the subject of formula.
[tex]\begin{gathered} y=-5+\frac{4x}{5} \\ \text{Multiply through by 5} \\ 5y=-25+4x \\ \text{Rewrite the equation} \\ -25+4x=5y \\ 4x=5y+25 \\ \text{Divide through by 4} \\ \frac{4x}{4}=\frac{5y}{4}+\frac{25}{4} \\ x=\frac{5y+25}{4} \end{gathered}[/tex]We can then write this properly in terms of the inverse function
[tex]g^{-1}(x)=\frac{5x}{4}+\frac{25}{4}[/tex]The domain of a function refers to the values of the independent variable (x), where the dependent variable [y or f(x)] or the function has a corresponding real value. The domain is simply the values of x for which the output also exists.
The domain of this inverse function is all real numbers because there would be a real number answer for every real number value of x.
