HELP PLZ. ASAP I need an answer.
Answer:
6.5
Step-by-step explanation:
You can see that the total Coast change from Month 0 to Month 2 by 13$ (35-22= 13). Since these are two month we need to divide them by 2 (13/2= 6.5)
6.5 is the total rate of change per months

5. Jordan works at the car wash a few hours a week and works mowing lawns for extra money.
Because of his schoolwork, he can't work more than 10 hours per week. Write a rule to see possible
solutions for his work schedule. Let x represent hours at the car wash, and y represent the hours
mowing lawns.
Answer:
The rule is
x + y ≤ 10
Step-by-step explanation:
Here, we want to write a rule that can help get solutions for the individual work hours
The number of hours for car wash is x while the number of hours for mowing lawns is y
Since he cannot work more than 10 hours, he can still work less than 10 hours
What we just have is that the addition of both working hours must not be over 10
So the rule to write is;
x + y ≤ 10
He width of a rectangular postcard is 4 inches and the diagonal is 7.6 inches long. What is the length of the postcard? Round your answer to the nearest hundredth.
Answer:
Adjacent = x = length = 6.46 inches
Step-by-step explanation:
Given the width and diagonal of a rectangular postcard,
Find the length using Pythagoras theorem
Hypotenuse ² = opposite ² + adjacent ²
Hypotenuse = 7.6 inches
Opposite = 4 inches
Adjacent = x
Hypotenuse ² = opposite ² + adjacent ²
7.6² = 4² + x²
57.76 = 16 + x²
subtract 16 from both sides
57.76 - 16 = x²
41.76 = x²
Find the square root of both sides
x = √ 41.76
= 6.46
x = 6.46 inches
Adjacent = x = length = 6.46 inches

Find the component form of the vector that represents the velocity of an airplane at the instant its wheels leave the ground, if the plane is going 75 miles per hour and the body of the plane makes an9° angle with the horizontal.
Answer:
The component form of the vector that represents the velocity of the airplane is [tex](74.1 i , \ 11.73j)\ mph[/tex]
Step-by-step explanation:
Given;
velocity of the airplane, v = 75 mph
direction of the plane, θ = 9°
The vertical component of the velocity is given by;
[tex]V_y = vsin\theta\\\\V_y = (75)(sin \ 9^0)\\\\V_y = 11.73 \ mph[/tex]
The horizontal component of the velocity is given by;
[tex]V_x = vcos \theta\\\\V_x = (75)(cos9^0)\\\\V_x = 74.1 \ mph[/tex]
Therefore, the component form of the vector that represents the velocity of the airplane is given as;
[tex](V_x , \ V_y) = (74.1 , \ 11.73)\ mph[/tex]

Answer:
x = 78
Step-by-step explanation:
(x-8) + 20 = 90
x - 8 = 90 - 20
x - 8 = 70
x = 70 + 8
x = 78
Check:
(78-8) + 20 = 90
70 + 20 = 90
The parabola with equation $y=ax^2+bx+c$ is graphed below:
(attached)
The zeros of the quadratic $ax^2 + bx + c$ are at $x=m$ and $x=n$, where $m>n$. What is $m-n$?
Answer:
[tex]m-n=2[/tex]
Step-by-step explanation:
Instead of using the standard form, we can use the vertex form of a quadratic equation:
[tex]f(x)=a(x-h)^2+k[/tex]
Where a is the leading coefficient, and (h, k) is our vertex.
Our vertex point is at (2, -4). So, let’s substitute 2 for h and -4 for k:
[tex]f(x)=a(x-2)^2-4[/tex]
Now, we need to determine a.
We know that it passes through the point (4, 12). So, when x is 4, y must be 12. In other words:
[tex]12=a((4)-2)^2-4[/tex]
Solve for a. Subtract within the parentheses:
[tex]12=a(2)^2-4[/tex]
Add 4 to both sides:
[tex]16=a(2)^2[/tex]
Square:
[tex]16=4a[/tex]
Solve:
[tex]a=4[/tex]
Thererfore, the value of a is 4.
So, our function is:
[tex]f(x)=4(x-2)^2-4[/tex]
Now, let’s find our roots. Set the equation to 0 and solve for x:
[tex]0=4(x-2)^2-4[/tex]
[tex]4=4(x-2)^2\\1=(x-2)^2\\x-2=\pm1 \\ x=2\pm1 \\ x=3\text{ or } 1[/tex]
So, our roots are 1 and 3.
The greater root is 3 and the lesser root is 1.
Therefore, m-n, where m>n, is 3-1 or 2.
Our final answer is 2.

What is the domain of the following function? Show work
f(x)=(2x-1)/((2x^2)-9x+10)
Step-by-step explanation:
f ( X) = ( 2X - I ) / 2X ^ 2 - 9X + 10
= 2X-1 ) /( 2X- 5 ) ( x - 2 )
set of zeros of denominator are :
2X- 5 . = 0
X= 5/2
or
X-2=0
X=2
set of zeros of denominator = { 5/2 ,2 }
domain = R - { 5/2,2 }
Write an equation for the following data plz :)
Answer:
y = 4x + 1
Y values increase by 4, X values increase by 1.
M or slope, = 4/1 or 4
Y-intercept is when x = 0
When x = 0 in this case, y = 1.
So,
y = 4x +1
Answer:
y = 4x + 1
Step-by-step explanation:
This is the y = mx + b format, hopefully its useful for you! It's a linear equation because all the values grow at a constant rate.
The y-intercept is 1 and it's rise over run which means that you start at 1 on your y-intercept when graphing and then rise 4 and run 1 to the right because it's a positive slope.
Tre has to pay $180 to book the recording studio plus $30 per hour of recording time. The function c(h)=30h+180 relates the total cost, c(h) of the recording session (in dollars) to the number of hours, (h) needed to record the tracks.
Answer:
1. $3302. 11.5 hoursStep-by-step explanation:
Continuation of the question:
1. Find c (5) and interpret your solution in the context of the problem 2. Find the value of h when c() = 525 and interpret your solution in the context of the problemSolution
c(h) = 30h + 1801 ...............................................
c(5) = 30*5 + 180 = $3302 ...............................................
525 = 30h + 18030h = 525 - 18030h = 345h = 345/30 h = 11.5 hoursJenny is renting a moving truck. She will have to pay a one-time fee for insurance coverage and pay the daily rate for the truck each day she uses it. The total cost of renting the truck in terms of the number of days the move will take can be modeled by the equation: y = 100x + 85. A. What is the slope? B. What is the y-intercept?
Answer:
Slope is 100
y-intercept is 85

The graph of a function f is shown below.
Find f(-2).
Answer:
-4
Step-by-step explanation:
The value of the function evaluated at [tex]x = -2[/tex] is -4.
The horizontal axis represents the set of the domain of the function, whereas the vertical axis is for the set of the range of the function. In this exercise, we need to need to find the value on the vertical axis that corresponds with a given value of the horizontal axis ([tex]x = -2[/tex]).
By direct inspection, we conclude that [tex]f(-2) = -4[/tex].

Answer:
37-9=28
Step-by-step explanation:
it was 28 F then rose 9 which is 37 so 37-9 =28
The equation is 37 - 9= x.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
After the temperature rose 9°F, the thermometer read 37°F.
let x be the temperature before the 9º increase.
So, 37 - 9= x
x= 28°F.
