how do i solve a function even or odd
Answers
Answer:
You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Nikolas and Angela were trying to solve the equation:
3x^2+10x=0
Nikolas said, “I can complete the square. Half of 10 is 5, and 5 squared is 25. So I'll add 25 to both sides, factor, and solve.”
Angela said, “I'll factor the left-hand side of the equation as x(3x+10), and solve using the zero product property."
Whose solution strategy will work?
Answers
zero product property (Angela)
Step-by-step explanation:Hi there !
(Angela)
3x² + 10x = 0
x(3x + 10) = 0
x = 0 => x₁ = 0
3x + 10 = 0 => 3x = - 10 => x₂ = - 10/3 = - 3 1/3

A triangle has perimeter 37 cm
Two sides of the shapes are put
together to make a pentagon
A square has perimeter 56 cm.
What is the perimeter
of the pentagon?
Answers
Take 56 and divide it by 4 since it’s a square and you’ll get 14. Subtract 14 from 37 because 14 is the bottom side of the triangle then you’ll have 23 left and that will be the other to side of the triangle. You’ll multiply 14 by 3 to get the square part of the pentagon and you get 42. Now 42+23 is 65
Members of a club are selling calendars as a fundraiser. The club pays $100 for a box of wall and desk calendars. They sell wall calendars for $12 and desk calendars for $8.Write an algebraic expression to model the club's profit from selling w wall calendars and d desk calendars.
Answers
Answer:
12w + 8d = 100
Step-by-step explanation:
Given:
Price of wall calendars = $12
Price of desk calendars = $8
Total amount pay = $100
Computation:
w = wall calendars
d = desk calendars
So,
Price of wall calendars(w) + Price of desk calendars(d) = Total amount
12w + 8d = 100
Lisa is sitting on the dock beside the lake she drops a rock from her hand into the lake after the rock hits the surface of the lake the rocks distance from the lake surface changed at a rate of -3 in./s if Lisa holds her hand 3 feet above the lake surface how hot how far from Lisa's hand is the rock five seconds after hits the surface
Answers
Answer: 4.2495 feets
Step-by-step explanation:
Given the following :
Rate of change (speed) when rock hits the lake surface = - 3in/s
Distance or depth after 5 seconds :
Distance = rate of change * time
Distance = (- 3 in/s × 5) = - 15 inches
1 inch = 0.0833 feet
15 inches = (-15 * 0.0833) = - 1.2495 feets
Distance between Lisa's hand and lake surface = 3 feets :
Distance between Lisa's hand and rock after 5 seconds :
(3 feets + 1.2495 feets) = 4.2495 feets

-16-14=6x+10x
-30=16x
x=-15/8
-15/8=x
Explanation:
-2(5x+8)=14+6x
1) Distribute -2 into the parentheses
-10x-16=14+6x
2) Combine like terms
Move -10x to the other side
-16=14+6x+10x
Move 14 to the other side
-16-14=6x+10x
-30=16x
3) Divide both sides by 16
-30/16=x
4) Simplify the fraction
-15/8=x

Given f (x) = 17 minus x squared, what is the average rate of change in f(x) over the interval [1, 5]?
Answers
Answer:
The average rate of change of the function over the given interval is -6
Step-by-step explanation:
The function we want to find its average rate of change is;
F(x) = 17 - x^2
Mathematically, the average rate of change of a function F(x) over an interval (a,b) can be calculated as;
{F(b) - F(a)}/(b-a)
According to this question, a = 1 and b = 5
F(a) = F(1) = 17 -(1)^2 = 17 -1 = 16
F(b) = F(5) = 17 - 5^2 = 17-25 = -8
So making the substitution; we have
(-8)-16/(5-1) = -24/4 = -6
Answer:
A: -6

Points A, C, U, D, S and E are all in the bottom floor plane. A plane is a flat surface, and saying "points are coplanar" means the points are all on the same plane.
Points like R, T and B are not on the floor plane, so they are not coplanar with the other points mentioned in the previous paragraph.
In other words, point R is not coplanar with points C, D and E since R is not on the floor plane with C,D,E.

B) The graph represents the function h(x) = 2x + 3
C)Point (3,0) represents the plant's height when purchased.
D)The plant grows about 1.5 inches each week.
E)The plant grows about 2 inches each week.
Answers
Answer:
A) The graph represents the function h(x) = 1.5x + 3
D)The plant grows about 1.5 inches each week.
Step-by-step explanation:
The following statements are true -
The graph represents the function h(x) = 1.5x + 3The plant grows about 1.5 inches each week.What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have Kay created a linear graph to track the height in inches [h] of a pepper plant over a number of weeks [x]. The plant's height was 3 inches when purchased.
Since the slope of the graph is 1.5 inches. We can write the equation of the graph as -
y = 1.5x + 3
This also shows, the plant grows about 1.5 inches each week.
Therefore, the following statements are true -
The graph represents the function h(x) = 1.5x + 3The plant grows about 1.5 inches each week.To solve more questions on straight lines, visit the link below-

Step-by-step explanation:
The Jenkins family and the Alexander family each used their sprinklers last summer. The water output rate for the Jenkins
family's sprinkler was 25 L per hour. The water output rate for the Alexander family's sprinkler was 40 L per hour. The
families used their sprinklers for a combined total of 45 hours, resulting in a total water output of 1425 L. How long was
each sprinkler used?
Answers
Answer:
Jenkins: 25 hours Alexanders: 20 hours
Step-by-step explanation:
To solve this problem we need to set up two equations. We know the rates of each sprinkler's output and how much total water was output. We know how many hours the sprinklers were on. We are looking for how long each sprinkler was used.
We can make a represent hours because we know the rate of sprinkler's output is per hour.
25a+40b=1425
a+b=45
Now to solve this system of equations we need to isolate a variable on one equation to plug into the other.
a+b=45
a=45-b
Now we can plug this in for a in the other equation.
25a+40b=1425
25(45-b)+40b=1425
Distribute 25 into the parenthesis.
1125-25b+40b=1425
1125+15b=1425
15b=300
b=20
Now we know that the Alexander family used their sprinklers for 20 hours. We can plug this back into the other equation to find b.
a+b=45
a+20=45
a=25
The Jenkins used the sprinklers for 25 hours, and the Alexanders used them for 20 hours.

An alternative method involves solving the original equation using the quadratic formula. After you get the two roots x = p and x = q, you should be able to find that p + 1/p = 5 and also q + 1/q = 5 as well.
In this case,
p = (5 + sqrt(21))/2
q = (5 - sqrt(21))/2
Answer:
