Answer:
vertex = (- 3, - 8 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = - 4(x + 3)² - 8 ← is in vertex form
with (h, k) = (- 3, - 8 ) ← vertex

A car rental company offers the following two plans for renting a car:
Plan A: 30 dollars per day and 11 cents per mile
Plan B: 50 dollars per day with free unlimited mileage
Q: How many miles must one drive in order to justify choosing Plan B?
Answer:
181.818181...Miles
Step-by-step explanation:
50 = 30 + 11X
X = 181.81818181...
If you multiply 11 by 181.81 repeting you will get 20 and 30 + 20 = 50
So You would have to go 181.81 repeating miles for it to be equal
If you are rounding up it would be 182 miles to justify choosing plan B

Winning the jackpot in a particular lottery requires that you select the correct three numbers between 1 and 44 and , in a separate drawing, you must also select the correct single number between 1 and 41. Find the probability of winning the jackpot.
Answer:
[tex]\frac{1}{3,492,544}[/tex]
Step-by-step explanation:
Since winning the lottery as described in the question is a series of events that need to occur in a sequence in order for it to be a winning ticket then this is a dependent event. Therefore to find the probability of actually winning we multiply the probability of getting each number which is calculated by dividing the amount of times the number appears by the total amount of numbers.
For example the first three numbers are 1 out of 44 therefore the probability of hitting just one correct number is [tex]\frac{1}{44}[/tex] ... now we multiply
[tex]\frac{1}{44} * \frac{1}{44} * \frac{1}{44} * \frac{1}{41} = \frac{1}{3,492,544}[/tex]
(Multiplying fractions is simply multiplying the numerators together and then the denominators together) Finally we see that the probability of actually winning the jackpot is [tex]\frac{1}{3,492,544}[/tex]

In a recipe for fizzy grape juice, the ratio of cups of sparkling water to cups of grape juice concentrate is 3 to 1. a) Find two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe.
Answer:
[tex]6:2,\,9:3[/tex]
Step-by-step explanation:
Given: The ratio of cups of sparkling water to cups of grape juice concentrate is [tex]3:1[/tex] in a recipe for fizzy grape juice.
To find: two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe
Solution:
Equivalent ratios are the ratios that have the same value.
Find two ratios equivalent to [tex]3:1=\frac{3}{1}[/tex]
Multiply both numerator and denominator of [tex]\frac{3}{1}[/tex] by 2
[tex]\frac{3(2)}{1(2)} =\frac{6}{2}[/tex]
Multiply both numerator and denominator of [tex]\frac{3}{1}[/tex] by 3
[tex]\frac{3(3)}{1(3)} =\frac{9}{3}[/tex]
So, two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe are [tex]6:2,\,9:3[/tex]

if an airplane rises at a rate of 42meters per second, how high will it be flying after 3 minutes
Answer
7560
Step-by-step explanation:
42* 60= 2520
2520* 3= 7560
The height of flying after 3 minutes will be 7560 meters.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall, and the difference between the abscissa is called run.
If an airplane rises at a rate of 42 meters per second.
Slope = 42 meters per second
Then the height of flying after 3 minutes will be
⇒ 42 meters per second x 3 minutes
⇒ 42 meters per second x 3 x 60 seconds
⇒ 7560 meters

The surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x + 12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month?
Sandra: y = 8 (32) + 12. y = 256 + 12. y = 268. The instructor receives 268 dollars a month from Sandra.
Answer:
Step-by-step explanation:
Y=8(32)+12
Y=256+12
Y=268 (Sandra)
Y=8(24)+12
Y=192+12
Y=204 (Bela)

a student worked out at the gym continuously for 50 minutes. The graph shows the remaining percentage of the workout f(x) as a linear function of x, the time in minutes
Answer:
Domain: All real numbers greater than or equal to 0 and less than or equal to 50
Range: All real numbers greater than or equal to 0 and less than or equal to 100
Step-by-step explanation
The workout is at 100% at 50 mins. Anything less would be under these two numbers. Since the percentage of workout is on the y-axis, anything between zero and 100 can be possible. The time is on the x-axis, so anything 0 to 50 can be possible.

|x-4|=6x+16 solve equation please
Step-by-step explanation:
|x-4|=6x+16 To find the absolute value :
x - 4 = 6x + 16 or x - 4 = -6x - 16 for first equation
x - 4 = 6x + 16 export like terms to the same side of the equation
-4 - 16 = 6x - x (The terms chages signs from negative to positive and from positive to negative when exported to the other sideof the equation)
-20 = 5x divide by 5
-4 = x
For the second equation
x - 4 = -6x - 16 export like terms to the same side of the equation
x + 6x = -16 + 4
7x = -12
x = 1.7 approximately

x = ±sqrt(7)
Step-by-step explanation:
3x^2 + 7 = 28
Subtract 7 from each side
3x^2 + 7-7 = 28-7
3x^2 = 21
Divide by 3
3x^2 /3 = 21/3
x^2 = 7
Take the square root of each side
sqrt(x^2) = ±sqrt(7)
