what would i put in, in the blanks? please help, i don’t get this
Answer:
Parent function
[tex]f(x)=\log_2(x)[/tex]
Since we cannot take logs of zero or negative numbers, the domain is [tex](0, \infty)[/tex] and there is a vertical asymptote at [tex]x=0[/tex].
There are no horizontal asymptotes and the range is [tex](- \infty,\infty)[/tex].
The end behaviors of the parent function are:
[tex]\textsf{As } x \rightarrow 0^+, f(x) \rightarrow - \infty[/tex]
[tex]\textsf{As } x \rightarrow \infty, f(x) \rightarrow \infty[/tex]
To determine the attributes of the given function, compare the given function with the parent function.
Given function
[tex]f(x)=- \log_2(x)+5[/tex]
The given function is reflected in the x-axis. Therefore, the end behaviors are a reflection of those of the parent function:
[tex]\textsf{As } x \rightarrow 0^+, f(x) \rightarrow \infty[/tex]
[tex]\textsf{As } x \rightarrow \infty, f(x) \rightarrow - \infty[/tex]
As the given function is translated vertically (5 units up) only, the domain, range and asymptote will not change, since the function has not been translated horizontally.
[tex]\textsf{Domain}: \quad (0, \infty)[/tex]
[tex]\textsf{Range}: \quad (- \infty, \infty)[/tex]
[tex]\textsf{Asymptote}: \quad x=0[/tex]
Conclusion
The function f(x) is a [tex]\boxed{\sf logarithmic}}[/tex] function with a [tex]\boxed{\sf vertical}}[/tex] asymptote of [tex]\boxed{x = 0}[/tex].
The range of the function is [tex]\boxed{(- \infty, \infty)}[/tex], and it is [tex]\boxed{\sf decreasing}[/tex] on its domain of [tex]\boxed{(0, \infty)}[/tex].
The end behavior on the LEFT side is as [tex]\boxed{x \rightarrow 0^+}[/tex], [tex]\boxed{f(x) \rightarrow \infty}[/tex], and the end behavior of the RIGHT side is [tex]\boxed{x \rightarrow \infty}[/tex], [tex]\boxed{f(x) \rightarrow -\infty}[/tex].

Multi choice choose the rule for the table year 8 level maths
Answer:
second option, x + 2y = 3
Step-by-step explanation:
The slope intercept form is y = mx + b
y = y coordinate
m = slope
x = x coordinate
b = y intercept
The y - intercept is when x = 0
In the table its shown that (0, 3), y = 3 so b = 3
The slope (gradient) is a number that describes both the direction and the steepness of the line.
slope = rise / run = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
(x_1, y_1) = coordinates of first point in the line
(x_2, y_2) = coordinates of second point in the line
x is increasing by 1 (run)
y is decreasing by 2 (rise)
rise / run = -2 / 1 = -2
so the slope is -2
our slope intercept equation is, y = -2x + 3
Choice:
Some choice are in standard form so we need to convert to slope intercept
y = x + 3 is already in the correct form2x + y = 3 becomes y = -2x + 3subtract 2x from both sides, 2x - 2x + y = 3 - 2x
x + 2y = 3 becomes y = -1/2x - 3/2subtract x from both sides, x - x + 2y = 3 - x becomes 2y = 3 - x
divided both sides by 2, 2y / 2 = (3 - x) / 2
x - y = 0 becomes y = xsubtract x from both sides, x - x - y = 0 - x than switch signs
which option matches?!

[tex]D= b^2-4ac[/tex][tex]D = (-2)^2-4*5*6 =4-120 =-116[/tex]Since the discriminant is negative, its square root is an imaginary number, hence there is no real solution.

what is 250/100 as a whole number?
Answer:
Unless im being completely braindead right now there isn't a whole number that works with this. When simplified its 5/2 or 2.5 but because it isn't an actual whole number (like 2, 4 and 6) they don't count.

Find the sum of the first 7 terms of the following series, to the nearest integer. 150,60,24...
Answer:
250
Step-by-step explanation:
The sum of the terms of a geometric series is given by the formula ...
Sn = a1×(1 -r^n)/(1 -r)
sum of n terms for first term a1 and common ratio r.
__
series sumThe given series has first term a1 = 150, and common ratio r = 60/150 = 2/5. Putting these values into the formula gives a sum of 7 terms that is ...
S7 = 150×(1 -(2/5)^7)/(1 -2/5) = 150((77997/78125)/(3/5))
S7 = 150×(25999/15625) = 249.5904
Rounded to the nearest integer, the sum of the first 7 terms is 250.

Which pair of angles are vertical angles?
Answer:
∠TRV and ∠WRS or ∠TRS and ∠WRV
Step-by-step explanation:
Vertical angles are angles that share a vertex and have sides that are opposite rays. That is, the opposites of the rays that form one of the angles are the rays that form the other angle.
__
Where lines cross, two pairs of vertical angles are formed. In your diagram, those pairs are ...
∠TRV and ∠WRS . . . . one vertical angle pair
∠TRS and ∠WRV . . . . another vertical angle pair

Additional comment
In this diagram, the ray RU is of no consequence with respect to any vertical angles. It can be ignored.
The vertical angles will each have one red ray and one blue ray as sides. These rays have end point R. No sides are shared.

Step-by-step explanation:

Answer:
Given translation:
4 units left3 units downTherefore,
To translate a point 4 units left, subtract 4 units from the x-value. To translate a point 3 units down, subtract 3 units from the y-value.⇒ (x, y) → (x - 4, y - 3)
Calculations
A (2, -1) ⇒ (2 - 4, -1 - 3) = A' (-2, -4)
B (1, -4) ⇒ (1 - 4, -4 - 3) = B' (-3, -7)
C (3, -5) ⇒ (3 - 4, -5 - 3) = C' (-1, -8)
D (5, -3) ⇒ (5 - 4, -3 - 3) = D' (1, -6)
Therefore, the new coordinates using prime notation are:

Answer:15
Step-by-step explanation:
A ladder is resting against a wall.The top of the ladder touches the wall at a height of 9 feet.Find the length of the ladder if the length is 3 feet more than its distance from the wall.
Let the distance of the ladder from the wall be x
The length of the ladder = x+3
The ladder touches the wall at a vertical height of 9 feet.
(x+3)^2 = x^2 + 9^2 ( using the pythagoras theorem
x^2 + 6x+ 9 = x^2 + 81
x^2- x^2 +6x = 81-9
6x= 72
x= 12
Therefore the length of the ladder will be x+3 = 12 + 3 =15 Answer.
