Consider functions fand g.
f(x) = -13
g(x) = |1/8x-1|
Answer:
We conclude that
(g o f) (4) = 9
Hence, option C is correct.
Step-by-step explanation:
Given
f(x) = -x³
g(x) = |1/8x - 1|
To determine
(g o f) (4) = ?
Using the formula
(g o f) (4) = g[(f(4)]
first we need to determine f(4)
so substituting x = 4 into f(x) = -x³
f(x) = -x³
f(4) = -(4)³ = -64
so
(g o f) (4) = g[(f(4)] = g(-64)
so substitute x = -64 in g(x) = |1/8x - 1|
[tex]g\left(x\right)=\left|\frac{1}{8}x-1\right|[/tex]
substitute x = -64
[tex]g\left(-64\right)=\left|\frac{1}{8}\left(-64\right)-1\right|[/tex]
[tex]=\left|-\frac{1}{8}\cdot \:64-1\right|[/tex]
[tex]=\left|-8-1\right|[/tex]
[tex]=\left|-9\right|[/tex]
Apply absolute rule: |-a| = a
[tex]=9[/tex]
Therefore, we conclude that
(g o f) (4) = 9
Hence, option C is correct.

What is the image of the point (-9, 1) after a rotation of 90° counterclockwise about
the origin?
Answer:
(- 1, - 9 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) , so
(- 9, 1 ) → (- 1, - 9 )
The image of the point (-9, 1) after a rotation of 90° counterclockwise about the origin is (1, 9).
What is rotation rule of 90°?Here are the rotation rules: 90° clockwise rotation: (x, y) becomes (y, -x) 90° counterclockwise rotation: (x, y) becomes (-y, x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).
The given coordinate point is (-9, 1).
Rule: (x, y)→(y, -x)
The image of the point (-9, 1) is
(-9, 1)→(1, 9)
Therefore, the image of the point (-9, 1) after a rotation of 90° counterclockwise about the origin is (1, 9).

For what value of x can the given lengths
be side lengths of a right triangle?
28, x, 53
Answer:
45
Step-by-step explanation:
The formula for finding the longest size of a right angle is
[tex]c^{2} = a^{2} + {b}^{2}[/tex]
a = 28, b = ? and c = 53;
Therefore, if you make b the subject of the formula, you will have
[tex]b = \sqrt{ {c}^{2} - {a}^{2} } [/tex]
And after plugging the value of c=53 and a=28, b is gotten to be 45

A tablet computer costs $356. Inez has saved $140 and hopes to save $12 per week until she can purchase a tablet computer. Which equation can be used to find the number of weeks, w, until Inez can purchase the tablet computer?
Answer:
D
12w + 140 = 356
Step-by-step explanation:
Her goal is to save up 356$. She already has 140$, and wants to save 12$ per week. We're trying to find how many weeks it would take.
You must multiply 12 by the number of weeks, which elimates the first two equations. We're also trying to add together 140 and the 12x because we want the total to ADD to 156.
Hopefully this makes sense, and ask any remaining questions about this in the comments. If you liked my explaination, feel free to give a Brainliest :P

Jerry started sit-ups every day . The first day he did 15 sit up . Everyday he did 2 more sit ups than he did the previous day today jerry did 33 sit-ups
Answer:
2x+15=33
Step-by-step explanation:
Computation of the equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day
Based on the information given the EQUATION will be :
2x+15=33
Where,
x represent Jerry Sit up numbers of days excluding the first day
2x represent the additional 2 more sit ups
2x +15 represent the total number of sit up that was done after the first day
2x+15=33 represent the total 33 sit-ups that jerry did today
Therefore the EQUATION that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day will be 2x+15=33
Jason and Monica each need to put 1 gallon of water into a pot.Jason has a measuring cup that holds 1 cup.Monica has a measuring cup that holds 1 pint. How many more times does Jason need fill the measuring cup than Monica?
Answer:
8 more times than
Step-by-step explanation:
We are told in the above question that:
Jason and Monica each need to put 1 gallon of water into a pot.
It is important to note that:
1 liquid gallon = 16 cups
1 liquid gallon = 8 liquid pints
For Jason
Jason has a measuring cup that holds 1 cup.
1 liquid gallon = 16 cups
In order to fill the pot, Jason has to use the cup 16 times
For Monica
Monica has a measuring cup that holds 1 pint.
Monica has to fill the pot using her measuring cup 8 times
How many more times does Jason need fill the measuring cup than Monica?
This is calculated as:
16 times - 8 times
= 8 times
Therefore, Jason needs to fill the measuring cup 8 more times than Monica
Y=-x^2-12x-37 find the 1) Roots 2) Factors 3) Vertex (x,y) 4) Interception with 'Y" axis 5) Axis of Symmetry 6)Direction of Opening 7)Max / Min ? Coordinates 8)Sketch 9) Domain 10) Range
Answer:
1) The roots of the equation Y = -x² - 12·x - 37 are x = -6 - √73 and -6 + √73
2) The factors of the function Y = -x² - 12·x - 37 are (x + (-6 - √73)) and (x - (-6 + √73))
3) The vertex is (-6, -1)
4) The Y-intercept is (0, -37)
5) The axis of symmetry is x = -6
6) The parabola opens downward
7) The maximum point is (-6, -1)
8) The graph of the function created with Microsoft Excel is attached
9) The domain of the function is -∞ < x < ∞
10) The range of the function is -∞ < Y ≤ -1
Step-by-step explanation:
The given function is Y = -x² - 12·x - 37
1) The roots of the equation Y = -x² - 12·x - 37 is given as follows;
0 = -x² - 12·x - 37
∴ -x² - 12·x - 37 = 0
The roots are;
x = (12 ± √((-12)² - 4 × 1 × (-37)))/(-2)
∴ x = -6 - √73 and -6 + √73
2) The factors are (x + (-6 - √73)) and (x - (-6 + √73))
3) The vertex is given by h = -b/(2·a) = 12/(2) = -6
k = c - b²/(4·a) = -37 - 144/(-4) = -1
The vertex = (h, k) = (-6, -1)
4) The intercept with the "Y" axis is given when x = 0, therefore, the y-intercept is (0, -37)
5) The axis of symmetry can be found at the vertex or the line x = -6
6) The sign of the coefficient of x² is negative therefore, the parabola opens downward
7) The maximum point is given as follows;
At the maximum point, dY/dx = d(-x² - 12·x - 37)/dx = -2·x - 12 = 0
x = 12/(-2) = -6, which is the vertex, therefore Y = -(-6)² - 12×(-6) - 37 = -1
The maximum point is the vertex (-6, -1)
8) Please find attached the graph of the function created with Microsoft Excel
9) The domain of the function is -∞ < x < ∞
10) The range of the function is -∞ < Y ≤ -1

Write the algebraic rule that represents the dilation that was applied.
You Try:
Which rule best represents the dilation that has been applied?
(x, y) → (2x, y)
(x, y) → (0.5x, 0.5y)
(x, y) → (2x, 2y)
(x, y) → (2 + x,2 + y)
Wednesday
Video Example:
Triangle XYZ is dilated with the origin as the center of dilation using the rule (x, y)(0.5x, 0.5y) to create Triangle X’Y’Z’. Which statement is true?
Triangle A’B’C’ is larger than Triangle ABC, because the scale factor is greater than 1
Triangle A’B’C’ is smaller than Triangle ABC, because the scale factor is less than 1
Triangle A’B’C’ is smaller than Triangle ABC, because the scale factor is greater than 1
You Try:
A figure will be dilated on a coordinate grid to create a smaller figure. The figure is dilated using the origin as the center of dilation. Which rule could represent this dilation?
(x, y) (0.5 + x, 0.5+y)
(x, y) (0.5 - x, 0.5-y)
(x, y) (32x, 32y)
(x, y) (23x, 23y)
Answer:
The answer is below
Step-by-step explanation:
The question is not complete but i would show how to solve.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are dilation, rotation, translation and reflection.
Dilation is the enlargement or reduction in the size of a figure.
a) If an point A(x, y) is dilated by a factor k, the new coordinate is A'(kx, ky). From the above options the ones that represent dilation is (x, y) → (0.5x, 0.5y) and (x, y) → (2x, 2y) . If the object is reduced then the correct option is (x, y) → (0.5x, 0.5y) while if the object is enlarged the correct option is (x, y) → (0.5x, 0.5y)
b)Dilation is the enlargement or reduction in the size of a figure by a factor k. If k < 1, then it is a reduction and if k > 1, it is an enlargement.
Since Triangle XYZ is dilated with the origin as the center of dilation using the rule (x, y)⇒(0.5x, 0.5y) to create Triangle X’Y’Z’, since the factor is less than 1(0.5 < 1), it is a reduction. Hence Triangle X’Y’Z’ is smaller than Triangle XYZ, because the scale factor is less than 1
c) The dilation creates a smaller figure hence the factor of dilation should be less than 1.
