Complete the equation of the line through (-8, 8) and (1, -10).
Use exact numbers.
y =
Answer:
y = -2x - 8
Step-by-step explanation:
Find the slope using rise/run (y2 - y1) / (x2 - x1)
(-10 - 8) / (1 + 8)
-18/9
= -2
Next, plug in the slope and a point into the equation to find b:
y = mx + b
-10 = -2(1) + b
-10 = -2 + b
-8 = b
Now, plug this and the slope into the equation:
y = -2x - 8
An NFL kicker will get paid based on the average hang time of his kicks. His average hang time is modeled by the following question: h=-16t^2 +97.6t. How many seconds do his kicks remain in the air on average?
Answer:
6.1 seconds
Step-by-step explanation:
set the equation equal to zero
0 = -16t² + 97.6t
factor out t
t(-16t + 97.6) = 0
-16t =- 97.6
t = 6.1
The NFL kicker's kicks remain in the air on average for approximately 3.05 seconds.
To find the average hang time of the NFL kicker's kicks, we need to determine the time at which the height (h) reaches its maximum value. The maximum height corresponds to the peak hang time.
The equation that models the hang time is given as: h = -16t^2 + 97.6t
This is a quadratic equation in the form: h = at^2 + bt + c
In our case, a = -16, b = 97.6, and c = 0 (since there is no constant term).
The time (t) at which the height (h) reaches its maximum value can be found using the formula: t = -b / 2a
Let's calculate the time (t):
t = -b / 2a
t = -97.6 / (2 * -16)
t = -97.6 / -32
t = 3.05 seconds (rounded to two decimal places)
So, the NFL kicker's kicks remain in the air on average for approximately 3.05 seconds.

Side AB of square ABCD is parallel to the Y axis and the perimeter of ABCD is 36. If the coordinates of point B is (5,17) . What is the coordinates of Pont D ?
============================================
Explanation:
The perimeter of the square is 36, so each side length is 36/4 = 9 units.
Point B is located at (5,17). We move down 9 units to get to (5,8), which is the location of point A. Then we move 9 units to the right to arrive at (14,8) which is point D's location.
Or we could go from B = (5,17) to C = (14,17) and then to D = (14,8). Each time we move 9 units.

Jacob’s age is two years more than the sum of the ages of his siblings Becky and Micah. Which equation represents Jacob’s age? A. z = x + y − 2; x represents Micah's age, y represents Becky's age, and z represents Jacob's age B. x = y + z + 2; x represents Jacob's age, y represents Micah's age, and z represents Becky's age C. x = 2 + y + z; x represents Becky's age, y represents Jacob's age, and z represents Micah's age D. y = x + z − 2; x represents Jacob's age, y represents Becky's age, and z represents Micah's age
The equation that represents Jacob's age is x = y + z + 2
From the question, the following information was provided :
Jacob's age is two years more than the sum of the ages of his siblings Becky and Micah.
This above information can be represented with the equation below
Jacob = 2 + ( Becky + Micah) (equation 1)
If :
x represents Jacob's age
y represents Micah's age
z represents Becky's age
Equation 1, can be rewritten as x = y + z + 2
Micah's age can be determined by making Micah the subject of the formula in the above equation
Micah = Jacob - Becky - 2 (equation 2)
If :
x represents Micah's age
y represents Becky's age
z represents Jacob's age
Micah's age can be rewritten as :
x = z - y - 2
Becky's age age can be determined by making Becky the subject of the formula in the first equation.
Becky = Jacob - Micah - 2 (equation 3)
If:
x represents Becky's age
y represents Jacob's age
z represents Micah's age
Equation 3 can be rewritten as :

Answer:
$70000
Step-by-step explanation:
For this problem, we need to convert the fractions into common denominators so we can get his total donated portion. From here, we can set up a proportion to fin his total income.
The greatest common denominator of 5 and 7 is 35. So
1/5 = 7/35. && 1/7 = 5/35
Add those together to get 7+5 = 12/35
So he gave away 12/35 of his income.
Now we set up a proportion to find his total.
35 / 12 = x / 24000
And now we solve for x:
x = (24000 * 35) / 12
x = 70000
So Mr. Pollard made $70000.
We can verify this by saying 24000 / 70000 to get the same reduced fraction 12/35.
Cheers.

Which of the two functions below has the largest maximum y-value?
f(x) = -x4- 2
g(x) = -3x3 + 2
Answer:
g(x)=-3x^{3}+2
Step-by-step explanation:
g(x) has a range that of (-infinity, +infinity), whereas f(x) has a range of (-infinity, -2].
Answer:
Step-by-step explanation:
● f(x) = -x^4 -2
● g(x) = -3x^3 + 2
Derivate both functions:
● f'(x) = -4x^3
● g'(x) = -9x^2
Solve the equations f'(x) =0 and g'(x) =0
● f'(x) = 0
● -4x^3 = 0
● x^3 = 0
● x =0
● g'(x) = 0
● -9x^2 = 0
● x^2 =0
● x = 0
So both functions f and g reach their maximum at 0.
● f(0) = 0^4-2 = -2
● g(0) = -3×0^3 +2 = 2
So g(0)>f(0)
So g has the largest maximum value.

On the coordinate plane below, Point P is located at (2,-3), and point Q is located at (-4,4). Find the distance between points P and Q Round your answer to the nearest whole number.
Answer:
9
Step-by-step explanation:
When given two points (x₁, y₁) and (x₂, y₂) on a plane, the Formula for the distance between the points is calculated as:
D= √(x₂ - x₁)² +(y₂ - y₁)²
In the question, we are given Point P is located at (2,-3), and point Q is located at (-4,4).
P(2, -3) , Q(-4, 4)
D = √(-4 - 2)² +(4 -(-3))²
D = √(-6)² + (7)²
D =√36 + 49
D = √85
D = 9.2195444573
Approximately to the nearest whole number, the distance between points P and Q is 9
