Complete a table with at least 5 points then graph the following quadratic on the coordinate plane. Identify all zeros.y = -2x2 + 5x + 8
Answer:
See attached
Step-by-step explanation:
Given function:
y = -2x² + 5x + 8Table and graph are attached
Zeros are included in the graph
Zero's are obtained:
x = 0 ⇒ y = 8
y = 0 ⇒ Solving quadratic equation
-2x² + 5x + 8 = 0x = (-5 ± √(25 + 2*4*8))/-4x = 3.608x = -1.108So zeros are (0, 8), (3.608, 0) and (-1.108, 0)

Answer:
[tex]x = \frac{-3d-9}{k-d}[/tex]
Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute d
-3d + dx = kx + 9
Step 3: Subtract 9 on both sides
-3d + dx - 9 = kx
Step 4: Subtract dx on both sides
-3d - 9 = kx - dx
Step 5: Factor out x
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d
[tex]x = \frac{-3d-9}{k-d}[/tex]
1-6(-X + 8) = -6x + 12
How many solutions are their
Answer:
no solution
Step-by-step explanation:
distribute -6 to get:
1-6x-48=-6x+12
the -6x on both sides cancels out giving you:
1-48=12
-47=12
since this isn't true there's no solution

Part D: Write an equation that would represent the
number of seconds it took the skydiver to reach a
height of 400 meters and use the equation to solve for
that time.
Part E: What is an appropriate domain for the
situation
A 0
B. 0
C. Sy s 44.7
DO Sy 5 760
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, the complete question is:
A skydiver is 760 meters above the ground when he opens his parachute. After opening the parachute, he descends at a constant speed of 17 meters per second.
a) A function gives a relationship between two variables (an independent and dependent variable). The dependent variable is dependent on other variables (output) while the independent variable is not dependent on other variables (input).
Let x be the number of seconds after the parachute is opened and y be the height of the parachute above the ground. Hence the equation that models the situation is:
y = 760 - 17x
At a height of 400 m, the number of seconds is:
y = 760 - 17x
400 = 760 - 17x
17x = 760 - 400
17x = 360
x = 21.2
x ≅ 21 seconds
It takes 21 seconds to reach a height of 400 m
b) Domain is the set of all independent variables. In this case the independent variable is the time (x)
The minimum time is at y = 760
y= 760 - 17x
760 = 760 - 17x
17x = 0
x = 0
The maximum time is at y = 0
y= 760 - 17x
0 = 760 - 17x
17x = 760
x = 44.7
Hence the domain = 0 ≤ x ≤ 44.7

The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes). The remaining credit after 32 minutes of calls is $21.16, and the remaining credit after 56 minutes of calls is $18.28. What is the remaining credit after 72 minutes of calls?
Answer:
The credit remaining on a phone card is 16.36 dollars
Step-by-step explanation:
A linear function is a polynomial function of the first degree of the form:
f (x) = m * x + b or y = m * x + b
where m is the slope of the linear function and b is the ordinate to the origin and it is the coefficient of the independent variable.
Given the coordinates of two points (x1, y1) and (x2, y2), you can determine the slope of the linear function using the following formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
The coefficient b is calculated simply by replacing any of the points in the linear function, knowing m, and isolating the value.
In this case you want the linear function first:
credit remaining on a phone card= m* the calling time in minutes + b
Being the points (32; 21.16) and (56;18.28), then the slope m will be:
[tex]m=\frac{18.28-21.16}{56-32}[/tex]
m= -0.12
Then, replacing the point (32; 21.16) in
credit remaining on a phone card= -0.12* the calling time in minutes + b
you get:
21.16= -0.12*32 + b → 21.16= -3.84 + b → 21.16 + 3.84= b → 25=b
Then, replacing the point (56;18.28) in
credit remaining on a phone card= -0.12* the calling time in minutes + b
you get:
18.28= -0.12*56 + b → 18.28= -6.72 + b → 18.28 + 6.72= b → 25=b
You can see that the value of b is the same.
So the linear function is:
credit remaining on a phone card= -0.12* the calling time in minutes + 25
Being the call time in minutes equal to 72, you replace this value in the linear function:
credit remaining on a phone card= -0.12* 72+ 25
and you get:
credit remaining on a phone card= -8.64+ 25
credit remaining on a phone card= 16.36
The credit remaining on a phone card is 16.36 dollars

solve for x 5(3a+2)=-65
Answer:
a = -5
Step-by-step explanation:
5(3a + 2) = -65 given
5*3a = 15 distributive property
5*2 = 10 distributive property
(15a + 10) = -65 the +10 goes to the other side as -10
15a = -75 divide 75/15
a = -5 result
One gym costs $24 per month and has a joining fee of $135. Another gym costs $39 per
month but does not have a joining fee. How many months would it take for each gym to
cost the same amount of money?
Answer:
It would take 1 month for the first gym (costs $24 per month) and 4 month for the second gym (costs $39 per month)
Step-by-step explanation:
If you add up $24 and $135 it equals 159. So for the first month you have to pay (in total) $159 dollars. So, if you want to get the same amount of money you have to multiply 39. To find out what number you need to multiply 39 with 4. Then you would have to add $3.
