in function notation, we get that the transformed function is:
g(x) = -2*f(x - 10) + 800
How to identify the transformation?
Here the parent function is:
f(x) = x^2
And the transformed function is the one graphed in the lower right side of the given image.
Notice that the y-intercept of the transformed function is y = 600.
The x-intercepts are x = -10 and x = 30
Then the polynomial is something like:
y = a*(x + 10)*(x - 30)
Using the fact that the y-intercept is y = 600, then:
600 = a*(0 + 10)*(0 - 30) = a*-300
600/-300 = a = -2
The transformed function is:
g(x) = -2*(x + 10)*(x - 30)
Expanding that:
g(x) = -2( x^2 + 10x - 30x - 300)
Completing squares we get:
g(x) = -2*( x^2 - 20x - 300)
= -2*(x^2 - 2*10*x - 300)
Now we can add and subtract 100, so we get:
-2*(x^2 - 2*10*x - 300 + 100 - 100)
-2*( (x - 10)^2 - 400)
Finally, expanding that:
g(x) = -2*(x - 10)^2 + 800
Writing it in function notation, we get that the transformed function is:
g(x) = -2*f(x - 10) + 800

9+(-4)+(-9)+4+8 with additive inverse
The additive inverse of the expression given as 9 + (-4) + (-9) + 4 + 8 is (-9) + 4 + 9 + (-4) -8
How to determine the additive inverse of the expression?The expression is given as
9 + (-4) + (-9) + 4 + 8
As a general rule, the additive inverse of an expression represented by x is
Additive inverse = -x
This means that
Expression = x
Additive inverse = -x
The above implies that we negate the expression to get the Additive inverse
So, we have
Expression = 9 + (-4) + (-9) + 4 + 8
This means that
Additive inverse = -[9 + (-4) + (-9) + 4 + 8]
Open the brackets
So, we have
Additive inverse = (-9) + 4 + 9 + (-4) -8
Hence, the additive inverse of the expression given as 9 + (-4) + (-9) + 4 + 8 is (-9) + 4 + 9 + (-4) -8

the angle measures less than 90°, thus, the correct classification is acute.
Which is the correct classification for the angle ∠JML?
First, let's define the possible angles that we have here:
Obtuse: With a measure larger than 90° and smaller than 180°Acute: With a measure between 0° and 90°Right: With a measure of 90°Straight: With a measure of 180°.Notice that the angles HML and LMK should add up to 180°, then we can write:
∠HML + ∠LMK = 180°
132° + ∠LMK = 180°
∠LMK = 180° - 132° = 48°
Now we can see that:
∠JML = ∠JMK + ∠LMK
∠JML = 41° + 48° = 89°
So the angle measures less than 90°, thus, the correct classification is acute.

Members of a softball team raised $1943.50 to go to a tournament. they rented a bus for $1148.50 and budgeted $53 per player for meals. write and solve an equation which can be used to determine x, the number of players the team can bring to the tournament.
The number of players the team can bring to the tournament are 15
Firstly we need to form the equation. The components of equation based on given information are as follows -
Total amount raised by softball team = Cost of bus + Cost of meal × number of players
Let the number of players be represented with x.
1943.50 = 1148.50 + 53×x
Rewriting the equation
53x = 1943.50 - 1148.50
Performing subtraction to Right Hand Side of the equation
53x = 795
Shifting 75 to Right Hand Side of the equation
x = 795 ÷ 53
Performing division at Right Hand Side of the equation
x = 15
Hence, 15 players the team can bring to the tournament.

Suppose an online electronics retailer is running two different specials. One deal will
get you 10% off your total purchase, and the other deal is worth $20 off a purchase
of $100 or more. Assuming you spend at least $100, if you are allowed to use both
deals, in which order do you want to apply them? Try the calculation both ways with
a few different prices, or write a formula to represent each option.
We get more money off when we follow order 1, that is, second deal follows first deal.
Given,
There are two deals in an online electronics retailer.
First deal: 10% off on your total purchase = x × (90/100)
Second deal: $20 off on a purchase of minimum $100 = x - 20
x be the money we spend.
We have to spend a minimum of $100.
They allowed us to use both deals.
We have to find the order of deals.
Lets check:
Order 1:
First deal, then Second deal.
First deal, x = 100
ie, x × (90/100) = 100 × (90/100) = 90
Second deal, x = 90
ie, x - 20 = 90 - 20 = 70
100 - 70 = 30
ie, $30 will get off when we apply this order.
Order 2:
Second deal, then first deal.
Second deal, x = 100
x - 20 = 100 - 20 = 80
First deal, x = 80
ie, x × (90/100) = 80 × (90/100) = 72
100 -72 = 28
ie, $28 will get off when we apply this order.
So, we can go for order 1.
Now lets check the same with x = 150 and x = 500
x = 150
Order 1:
First deal, then Second deal.
First deal: x = 150
ie, x × (90/100) = 150 × (90/100) = 135
Second deal, x = 135
ie, x - 20 = 135 - 20 = 115
150 - 115 = 35
ie, $35 will get off when we apply this order.
Order 2:
Second deal, then first deal.
Second deal, x = 150
x - 20 = 150 - 20 = 130
First deal, x = 130
ie, x × (90/100) = 130 × (90/100) = 117
150 - 117 = 33
ie, $33 will get off when we apply this order.
So, we can go for order 1.
x = 500
Order 1:
First deal, then Second deal.
First deal: x = 500
ie, x × (90/100) = 500 × (90/100) = 450
Second deal, x = 450
ie, x - 20 = 450 - 20 = 430
500 - 430 = 70
ie, $70 will get off when we apply this order.
Order 2:
Second deal, then first deal.
Second deal, x = 500
x - 20 = 500 - 20 = 480
First deal, x = 480
ie, x × (90/100) = 480 × (90/100) = 432
500 - 432 = 68
ie, $68 will get off when we apply this order.
So, we can go for order 1.
Lets conclude that,
We get more money off when we follow order 1, that is, second deal follows first deal.

Consumer affairs investigator records the repair cost for 10 randomly selected VCRs. A sample mean of $72.82 and standard deviation of $24.17 are subsequently computed. Determine the 90% confidence interval for the mean repair cost for the VCRs. Assume the population is approximately normal. Construct the 90% confidence interval. Round your answer to two decimal places.
We get that the critical value of the 90 % confidence interval is 1.833 and the interval is (58.81, 86.83).
We are given that the number of VCRs are 10.
So, we get that:
Sample size = n = 10
Now, we get the degree of freedom as:
d o f = n - 1
d o f = 10 - 1
d o f = 9
For 90% confidence interval , critical value will be:
t (0.10, 9) = 1.833
Lower limit of 90% confidence interval will be:
Lower interval = Mean - t (0.10,9) × s / √n
= 72.82-1.833 × 24.17 /√10
= 58.81
Upper limit of 90% confidence interval will be:
Upper interval = Mean + t (0.10,9) × s /√n
= 72.82 + 1.833 × 24.17/√10
= 86.83
Therefore, we get that the critical value of the 90 % confidence interval is 1.833 and the interval is (58.81, 86.83).

For Exercises 17 And 18, Find The Acute Angle Between The Given Lines By Using Vectors Parallel To The Lines.
y = x , y = 2 x + 3
The acute angle between the lines y = x and y = 2 x + 3 is 18.4349°.
We are given the lines:
y = x
y = 2 x + 3
The formula for finding the angles between two vectors is given by:
cos θ = u · v / | u | | v|
We know that (0,0) and (1, 1) lies on the line y = x.
Now, vector u for the line y = x will be:
u = (1,1) - (0,0) = {1, 1}
(0,3 ) and (1, 5) lies on the line y = 2 x + 3
Similarly, vector v will be equal to:
v = (1, 5) - (0, 3) = {1, 2}
cos θ = {1, 1} · {1, 2} / √1 + 1 √1 + 4
cos θ = 1 + 2 / √10
cos θ = 3 / √10
θ = cos⁻¹ ( 3 / √10)
θ = 18.4349°
