The quadratic function d = –3x^2 + 16 models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill. After how many seconds is the skateboarder 8 ft from the bottom of the hill?
Answers
Answer:
To find the solution, plug in 8 for d
d=-3x2+16
8=-3x2+16 Subtract 8 from both sides
0=-3x2+8
Now, use the quadratic equation to solve for x
a=-3
b=0
c=8
x=1.63 or
C. 1.6s
Step-by-step explanation:
The skateboarder is 8 feet from the bottom of the hill after 1.633 seconds.
What are Quadratic Functions?Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.
The general form of a quadratic function is f(x) = ax² + b x + c.
Given that,
Quadratic function which models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill is,
d = –3x² + 16
We have to calculate after how many seconds is the skateboarder 8 ft from the bottom of the hill.
d = 8 feet. Substitute it.
–3x² + 16 = 8
–3x² = 8 - 16
3x² = 8
x² = 8/3
x = √(8/3) seconds
≈ 1.633 seconds
Hence the time is approximately 1.633 seconds.

What is the y-intercept of this function?
f(x) = 2(x - 7)2 - 32
(0,-32)
(0,66)
(0,-7)
(0,17)
Answers
Answer:
(0, 66 )
Step-by-step explanation:
To find the y- intercept, let x = 0 and solve for y
f(0) = 2(0 - 7)² - 32
= 2(- 7)² - 32
= 2(49) - 32
= 98 - 32
= 66
The coordinates of the y- intercept are (0, 66 )

The lines shown below are parallel. If the green line has a slope of 5, what is
the slope of the red line?
Answers
Answer:
D
Step-by-step explanation:
By definition, any two lines that are parallel must have the same slope, since they are angled the same amount (they travel the same amount up over a certain sideways distance). Hope this helps!
The required slope of the red line is equal to 5. Option D is correct.
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The slope of the parallel line is always equal, so as of the given condition if green and red lines are parallel then the slope of the red line is equal to the slope of the green line.
The slope of the red line = slope of the green line
The slope of red line = 5
Thus, the required slope of the red line is equal to 5, Option D is correct.

Simplify each side of the equation.
6-4 = k-3k
Answers
Answer:
k = -1
Step-by-step explanation: 6-4 = k-3k
subtract: 2 = -2k
divide both sides by -2: k = -1
simplifying is easy! we simply add or subtract like terms on each side.
6-4=2
1-3=-2 and then add k which is the variable so -2k
The equation would be 2=-2k and then we can divide both sides by -2 to isolate the variable to get -1=k

B. x + 1 = -3(y-10)
C. y + 1 = -3(x-10)
D. y + 1 = 3(x-10)
Answers
Answer:
C
Step-by-step explanation:
Since we have a point and a slope, we can use the point slope formula.
The point slope formula is:
[tex]y-y_{1} =m(x-x_{1})[/tex]
where m is the slope, and (x1, y1) is the point given.
We know that the slope is -3, and the point given is (10, -1)
Therefore, our m is -3, x1 is 10, and y1 is -1.
y- -1 = -3(x-10)
y--1 is the same as y+1
y+1= -3(x-10)
Therefore, choice C is correct.

Tomas selects one of these garments at random. Let AAA be the event that he selects a blue garment and let BBB be the event that he chooses a shirt.
Please help!!!
Answers
Answer:
can u explain it more lol
Step-by-step explanation:
1)The probability of choosing a blue garment is 1/2
2)The probability of choosing a shirt is 1/3.
Thomas has 1 blue shirt
Thomas has 1 green shirt
Thomas has 1 blue hat
Thomas has 1 green scarf
Thomas has 1 blue pair of pants
Thomas has 1 green pair of pants
So, number of blue garments = 3
Number of shirts = 2
Total garments =6
What is probability?Probability is the measure of the likelihood of an occurrence.
P(event) = Favorable outcomes / Total outcomes
P(blue garment) = 3/6 =1/2
P(shirt) = 2/6 =1/3
Hence, 1)The probability of choosing a blue garment is 1/2
2)The probability of choosing a shirt is 1/3.
