Answer:
(-2, -1).
Step-by-step explanation:
y = x² + 4x + 3
Completing the square:
y = (x + 4/2)^2 - (4/2)^2 + 3
y = (x + 2)^2 - 4 + 3
y = (x + 2)^2 - 1.
This is vertex form and the coordinates of the vertex are (-2, -1).
I dont understand mean or median. Can someone help?
Answer:
both of these are ways to kinda categorize numbers.
MEAN- you're finding the average. average and mean are synonymous. meaning they're the exact same. with the mean, all you have to do is add all the numbers up and then divide that by however many numbers you added up
lets say you need to find the mean of a domain and you're given this set of numbers:
{1,2,3,4,5,6,7}
the sum is 28. You divide it by 7 (bc thats how many numbers you added up) and you get your mean to be 4
The MEDIAN is going to be simpler than you may think. put all the numbers in numerical order, greatest to least or least to greatest. it doesn't matter.
Then find the number in the middle. Some people like crossing off the numbers on either end until you get to the center. So like marking off 1 then 7 then 2 then 6 etc.
The median is 4.
Step-by-step explanation:
Of course, I'm glad to help.
Mean is average. So for example, if I had the numbers 2,3,4, and 5 the mean would be 10.25.
The steps to getting mean are adding up all your numbers then dividing by the number of equalities you have.
Median is the middle number in your group. For example, if I had numbers 2, 3, 4, 5, and 6. The median would be 4 because that the number in the middle.
But when you have an even amount of numbers (for example 2,3,4,5) you'd add up the ones in the middle (3 and 4) then divide them by 2 (3+4=7/2). In this case, the median would be 3.5.

Function g is represented by the equation.
g(x) = 4 (1/4)^x + 2
Which statement correctly compares the two functions?
A. they have different Y-intercepts but the same end behavior
B. they have the same Y-intercept and the same end behavior
C. they have the same Y-intercept but different end behavior
D. they have different Y-intercepts and different end behavior
Answer:
THE ANSWER IS A. They have different y-intercepts but the same end behavior.
I used Desmos to graph the function g(x)=4(1/4)^x+2
They have different y-intercepts because function f(x) is 4, while the y-intercept on graph is 6
But they have the same end behavior at 2.

Hi there!
A function is a set of ordered pairs that do not have same x-values.
In a set of ordered pairs, If two or more ordered pairs have same x-values, they are not considered as a function but rather a relation instead.
From the question above, you notice that two of the choices have same x-values and others don't have.
The relations that are not functions are the second choice and fourth choice because two ordered pairs have same x-values.
Any questions can be asked through comment.
Furthermore, a function is also a relation but a relation isn't always a function.
Hope this helps, and Happy Learning! :)

solve the equation 4 x - 6 = 6- 2x
Answer:
x=2
Step-by-step explanation:
4x-6=6-2x
(add 2x and 6 to both sides)
6x=12
(divide by six)
x=2
Double Check:
4(2)-6=2
6-2(2)=2
4(2)-6=6-2(2)
Answer:
x=2
Step-by-step explanation:
4x-6=6-2x
move the variables to right and constants to the left
4x+2x=6+6
combine like terms
6x=12
isolate x by dividing by 6 on both sides to find it's value
x=2
i hope this helps :)

Based on historical data, your manager believes that 43% of the company's orders come from first-time customers. A random sample of 243 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is between 0.2 and 0.39?
Answer:
Following are the solution to the question:
Step-by-step explanation:
[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]
z-score for [tex]\hat{p}=0.2[/tex] will be:
z score for will be:
[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]
[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.

Solve the following Equation
50 = 16 + d
Answer:
d = 34
Step-by-step explanation:
50 minus 16 equals 34, which means d must be equal to 34.
Answer:
D=34
Step-by-step explanation:
In order to find out what the value of d is, you need to subtract the total amount,50, from 16.
Therefore, D=34

A carpenter is constructing a staircase in a house. The distance from the first floor to the basement is 9.2 feet. The staircase will be 13.3 feet long. What angle do the stairs make with the basement floor?
Answer:
43.77°
Step-by-step explanation:
The height, h = first floor to basement = 9.2 feets
Length of staircase = hypotenus = 13.3 feets
Angle stacase makes with basement floor, θ
Using trigonometry :
Sinθ = opposite / hypotenus
Opposite = height = 9.2 feets
Sinθ = 9.2 / 13.3
Sinθ = 0.6917293
θ = sin^-1(0.6917293)
θ = 43.77°

Solve:
2^x-3= 1/8
(and if you can, put a step by step. you don't have to though)
Answer:
[tex]x = 0[/tex]
Step-by-step explanation:
Write the number in exponential form with the base of 2:
[tex] {2}^{x - 3} = {2}^{ - 3} [/tex]
Since the bases are the same, set the exponents equals.
[tex]x - 3 = - 3[/tex]
Cancel equal terms on both sides of the equation:
[tex]x = 0[/tex]
[tex]2 {}^{x - 3} = \frac{1}{8} [/tex]
To Find value of 'x'
Solution[tex]2 {}^{x - 3} = \frac{1}{8} \\ \\ \implies2 {}^{x - 3} = 2 {}^{ - 3} \\ \\ \\ Since \: Bases \: Are \\ Equal \: We \: Need \\ To \: Evaluate \\ The \: Powers \\ \\ \implies \: x - 3 = - 3 \\ \\ \implies x = - 3 + 3 \\ \\ \implies \: x = 0[/tex]
