If the perimeter of a pool is 102ft, and the length is 6 more than twice the width, what are the dimensions?
Answers
Length = 36 ft
Width = 15 ft
Step-by-Step Explanation:
Let length of pool be ‘x’ ft
Let width of pool be ‘y’ ft
Perimeter = 2(x + y) = 102 ft
By Given:
2(x + y) = 102
=> 2x + 2y = 102 (Eq. 1)
=> x = 2y + 6 (Eq. 2)
Substitute value of ‘x’ from Eq. 2 in 1 :-
2x + 2y = 102
2(2y + 6) + 2y = 102
4y + 12 + 2y = 102
6y + 12 = 102
6y = 102 - 12 = 90
=> y = 90/6 = 15
Therefore, y = 15
Substitute value of ‘y’ in Eq. 2 :-
x = 2y + 6
x = 2(15) + 6
x = 30 + 6
=> x = 36
Therefore, x = 36
Verification:
2x + 2y = 102
2(36) + 2(15) = 102
72 + 30 = 102
=> 102 = 102
LHS = RHS
Therefore,
Length (x) = 36 ft
Width (y) = 15 ft
A line that passes through the points (x, 4) and (6, -1) has a slope of 56. what value of x will yield the given slope?
Answers
The value of x that yields a slope of 56 is 6.09
How to determine the value of x?The given parameters are:
Slope = 56Points: (x,4) and (6,-1)The slope of two points is:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
This gives
[tex]\frac{-1 -4}{6 -x} = 56[/tex]
Evaluate the difference
[tex]\frac{-5}{6 -x} = 56[/tex]
Cross multiply
56(6 - x) = -5
Divide both sides by 56
6 - x = -0.09
Make x the subject
x = 6 + 0.09
Evaluate
x = 6.09
Hence, the value of x that yields a slope of 56 is 6.09

A ball is dropped from a height of 600 feet. The function describing the height of the ball at t seconds after it dropped is [tex]f(t)=-16t^2+600[/tex].
a) Find the average velocity of the object during the first 3 seconds.
b) Verify that at some time during the first 3 seconds the instantaneous velocity equals the average velocity. Find that time.
The average velocity: _ ft/sec
The instantaneous velocity equals to the average velocity at t = _ sec
Answers
The average velocity of the object after during the first three seconds is: 48m/s
The time at which the instantaneous velocity equals the average velocity within the first three seconds is 1.5 seconds.
What is instantaneous and average velocities?Instantaneous velocity is the speed of an object at a particular point in time.
Average velocity is the velocity of an object after covering a certain distance for a period of time
Analysis:
Given
initial height = 600 feet
Height with respect to time = f(t) = -16[tex]t^{2}[/tex] + 600
a) Height at t = 0 = 600 feet
Height at t = 3 seconds = f(3) = -16[tex](3)^{2}[/tex] + 600 = 456 feet
Distance travelled = 600 - 456 = 144 feet
Average velocity = distance travelled/time taken = 144/3 = 48 feet/seconds
b) instantaneous velocity at time t = [tex]\frac{df(t)}{dt}[/tex] = [tex]\frac{d(-16t^{2} + 600) }{dt}[/tex] = -32t
when instantaneous velocity equal average velocity
-32t = -48
t = 1.5 seconds
In conclusion, the Average velocity after 3 seconds is 48 feet per seconds and the time taken for the average velocity to equal the instantaneous velocity is 1.5 seconds.

Step-by-step explanation:
no, no, you use the equation to identify a, b and c.
then you use the formula with these values to get the solutions to the equation (the values of x for which the equation delivers 0).
always remember, a quadratic equation always has 2 solutions. sometimes at least one of them are not a real number, sometimes the 2 springs are equal, ...

a, b, c are the factors of the terms in x and the constant term.

x = (4 ± sqrt((-4)² - 4×1×-2))/(2×1) =
