1) Multiplication by -1.
This implies F(x) is flipped over x-axis
2) Multiplication by 1/3
This implies F(x) is compressed vertically
3) Addition of 4 to x.
This implies F(x) is shifted by 4 units to left.
Thus, G(x) is obtained from F(x) by flipping it across x-axes, compressing it vertically and shifting it towards left.
Thus, option C is the correct answer

Two trains leave stations 532 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at 100 miles per hours. How long will it take for the two trains to meet?
Answers
The two trains will meet in 2.4 hours.
What is the distance?Distance is defined as the product of speed and time.
We have been given that two trains depart from stations 532 miles apart at the same time and head in the opposite direction. The first train runs at 90 miles per hour, while the second at 100 miles per hour.
Let's assume x distance 90 mph train traveled
Then (532 - x) is the distance 100 mph train traveled
Travel time = distance/speed (equal in both directions)
⇒ x/90 = (532 -x)/100
⇒ 100x = 90× 532 - 90x
⇒ 100x + 90x = 47880
⇒ 190x = 47880
⇒ x = 47880/190
⇒ x = 252
So travel time = 252/90 = 2.4 hrs
Therefore, the two trains will meet in 2.4 hours.

Determine if the function is an even function, an odd function or neither. y=-5x^(2)-2x+6
Answers
A function is even if, for each x in the domain of f, f (- x) = f (x). The even functions have reflective symmetry through the y-axis.
A function is odd if, for each x in the domain of f, f (- x) = - f (x). The odd functions have rotational symmetry of 180º with respect to the origin.
For y = -5x ^ (2) -2x + 6 we have:
f (-x) = - 5 (-x) ^ (2) -2 (-x) +6
f (-x) = - 5x ^ (2) + 2x + 6

one day a store sold 12 sweatshirts white one cost $9.95 and yellow ones cost $12.50. In all 147.45 worth of sweatshirts were sold how many of each color were sold?
Answers
y= # of yellow sweatshirts
STEP 1:
set up quantity and cost equations
QUANTITY EQUATION
x + y= 12
COST EQUATION
$9.95x + $12.50y= $147.45
STEP 2:
solve for one variable in quantity equation
x + y= 12
subtract y from both sides
x= 12 - y
STEP 3:
substitute x value in step 2 in cost equation
$9.95x + $12.50y= $147.45
9.95(12 - y) + 12.50y= 147.45
multiply 9.95 by parentheses
(9.95*12) + (9.95*-y) + 12.50y= 147.45
119.40 - 9.95y + 12.50y= 147.45
combine like terms
119.40 + 2.55y= 147.45
subtract 119.40 from both sides
2.55y= 28.05
divide both sides by 2.55
y= 11 yellow
STEP 4:
substitute step 3 x value in either equation
x + y= 12
x + 11= 12
x= 1 white
CHECK:
$9.95x + $12.50y= $147.45
9.95(1) + 12.50(11)= 147.45
9.95 + 137.50= 147.45
147.45= 147.45
ANSWER: 1 white sweatshirt and 11 yellow sweatshirts were sold.

Marcus has a pool that can hold a maximum of 4500 gallons of water. The pool already contains 1500 gallons of water. Marcus begins to add more water at a rate of 30 gallons per minute. Write an inequality that shows the number of minutes, m, Marcus can continue to add water to the pool without exceeding the maximum number of gallons.
Answers
4500 - 1500 = 3000
Because we need to represent an inequality:
30m = 3000
Divide both by 30:
m = 100
It will take 100 minutes
Answer:
Inequality is m ≤ 1000
Step-by-step explanation:
Capacity of the pool to hold the maximum water is = 4500 gallons of water.
Pool is already having 1500 gallons of water so remaining volume of the pool that can be filled is = 4500 - 1500 = 3000 gallons
Marcus begins to add 30 gallons water per minute and it takes "m" minutes to fill the remaining volume.
So amount of water required = 30m gallons
There is a condition that Marcus continues to add water without exceeding the maximum amount of water.
This means remaining amount "3m gallons" will be never cross the limit of "3000 gallons" of remaining volume of water.
Now we can form the inequality as 3m ≤ 3000
or m ≤ 1000
Therefore, answer is m ≤ 1000

Which number produces an irrational number when added to 2/5? A) 0.555... B) -0.4 C) -/`5 D) 2/7
Answers
Answer to this question is pie of 5
The number that produces an irrational number when added to 2/5 is 0.55....
What is a rational number?A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
To produce an irrational number when added to 2/5, the number must be irrational itself.
Therefore, options B, C, and D are eliminated since they are all rational numbers.
Option A, 0.555..., is a repeating decimal and can be expressed as a fraction of 5/9. When added to 2/5, we get:
2/5 + 5/9 = (18/45) + (25/45) = 43/45
Since 43/45 is not a rational number, the answer is A) 0.555...

Go to lesson page Problem If you flip three fair coins, what is the probability that you'll get a head on the first flip, a tail on the second flip, and another head on the third flip?
Answers
Your probability of the given sequence of 3 coin flips is
2^-3 = 1/8
First if all, we know that the coin has two sides- head and tail
P(getting a head of the first flip):
1/2
P(getting a tail on the second flip):
1/2
P(getting a head on the third flip):
1/2
To find the final answer, take:
1/2×1/2×1/2=1/8
As a result, the probability that you'll get a head on the first flip, a tail on the second flip, and another head on the third flip is 1/8. Hope it help!

Logarithmic form x^19 = y
Answers
1. You have the following expression given in the problem:
x^19 = y
2. By definition, you have:
logb(x)=y
b^y=x
3. Therefore, you have:
x^19 = y
logx(y)=19
4. Then, as you can see, the answer is: logx(y)=19
b ^ x = a , then to solve for the exponent x, log b a = x or read as log a base b = x.
x^19 = y
x = b
a = y
x = 19
log x y = 19 or log y base x = 19
In a family with 8 children, excluding multiple births, what is the probability of having 7 boys and 1 girl, in any order? assume that a boy is as likely as a girl at each birth
Answers
The probability of having 7 boys and 1 girl in a family with 8 children is 1/128.
Explanation:To find the probability of having 7 boys and 1 girl in a family with 8 children, we can use the concept of combinations. There are 8 children in total, and we want to choose 7 boys and 1 girl from them. The probability of having a boy or a girl at each birth is 50%, so we can use the binomial coefficient to calculate the probability. The formula for the binomial coefficient is C(n, k) = n! / (k!(n-k)!), where n is the total number of children and k is the number of boys we want. Plugging in the values, we get C(8, 7) = 8! / (7!(8-7)!) = 8. Therefore, the probability of having 7 boys and 1 girl in any order in a family with 8 children is 8 / 2^8 = 1 / 128.

Option C is correct.
Step-by-step explanation:
we have to choose the option for which the value is equals to sin(70°)
As in the first quadrant sine and cosine both are positive
[tex]\sin \theta = \cos (90-\theta)\\\\\sin (70^{\circ})= \cos (90-70)=\cos (20^{\circ})\\\\sin (70^{\circ})=cos (20^{\circ})[/tex]

What is the y-intercept of the quadratic function fx) (x- 6)(x-2)?
Answers
To find the y-intercept of a quadratic that is in factor formed follow the steps below:
First take the factor form and put it into standard quadratic form
Standard quadratic form:
[tex]ax^2 + bx + c[/tex]
To put the the factor form of a qudratic into standard form, we use the foil method
(x-6)(x-2) = [tex]x^2 - 8x +12[/tex]
Now to find the y-intercept, input 0 where the x is located:
[tex]f(x) = x^2 - 8x +12[/tex]
[tex]f(0) = 0^2 - 8(0) +12[/tex]
[tex]f(0) = 12[/tex]
y-intercept = (0,12)
Why did I use 0? Remember the y-intercept is where the line crosses the y axis so this means the x value of the y intercept is always = 0. Also, not, to find the y-intercept, you could of just multiplied the 6 and 2 in the factored form to get the 12 and since you know that the x is always 0 at the y-intercept, you know that the y-intercept is at (0,12)
Option 2
Input 0 for x in f(x) = (x-6)(x-2)
f(x) = (x-6)(x-2)
f(0) = (0 - 6)(0 - 2)
f(0) = (6)(2) = 12
x = 0
f(0) = y = 12
y-intercept = (0,12)

The endpoints of a line segments are at the coordinates (-6,3,4) and (4,-1,2) what is the midpoint of the segment
Answers
Explanation:
The coordinates of the mid point are calculated by dividing the sum of each pair of corresponding coordinates by 2.
This is how you calculate the mid of each coordinate separately:
1) x-coordinate:
mid x-coordinate = (- 6 + 4) / 2 = -2 / 2 = - 1
2) y-coordinate
mid y-coordinate = (3 - 1) / 2 = 2 / 2 = 1
3) z-coordinate
mid z-coordinate = (4 + 2) / 2 = 6 / 2 = 3
So, the midpoint is (-1, 1 , 3)
