The scatter plot shows the profit by the month for a new company during its first year of operation. Which equation most closely models the line of best fit for the scatter plot? A) y = 5x B) y = 2.5x C) y = 5x + 1000 D) y = 2.5x + 1000
The equation most closely models the line of best fit for the scatter plot is y = 2.5x
Equation of a lineA line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b
m is the slopeb is the intercept
Using the coordinate points on the line (3, 5000) and (9, 20000)
Get the slope
Slope = 20000-5000/9-3
Slope = 15000/6 = 2500
Determine the y-intercept
5000 = 2500(3) + b
b = 5000 - 7500
b = -2500
Determine the equation
y = 2.5x - 2.5
Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

For the first wedge, you have 6 numbers to choose from .
For the second wedge , you have 5 numbers to choose from .
For the 3rd wedge , you have 4 numbers to choose from .
For the 4th wedge , you have 3 numbers to choose from .
For the 5th wedge , you have 2 numbers to choose from .
For the 6th wedge , you have 1 number to choose from .
Conclusion: this numbering can be done in:
6×5×4×3×2×1 = 720
Note :
Generally ,we write 6×5×4×3×2×1 as 6! and we read it 6 factorial.

Write the power (-2)³ in repeated multiplication form. Then find the value of the power.
The power in repeated multiplication form is
The value of the power is
Answer:
The power in repeated multiplication form is (-2)*(-2)*(-2)
The value of the power is -8
=====================================================
Reason:
Exponents represent repeated multiplication. The small number up top is the exponent that tells us how many copies of the base to multiply
In this case, the exponent 3 tells us we have 3 copies of "-2" multiplied together to get (-2)*(-2)*(-2)
This simplifies to -8
A baseball player hits a pitched ball when it is 4 ft above the ground. The initial upward velocity is 80 ft/s. How
long will it take for the ball to hit the ground?
Answer:
t=+4.06
Step-by-step explanation:
when the baseball hits the ground, the height will be 0.
h=0we are given that h=−16t2+64t+4.
this means that the height is 0 when −16t2+64t+4=0.−16t2+64t+4=0divide both sides by 4:−4t2+16t+1=04=0−4t2+16t+1=0 can be solved using the quadratic formula:t=−b±√b2−4ac2a, where at2+bt+c=0.at2+bt+c=−4t2+16t+1a=−4,b=16,c=1t=−b+√b2−4ac2aor−b−√b2−4ac2a−b+√b2−4ac2a=−16+√272−8=−0.06..−b−√b2−4ac2a=−16−√272−8=4.06 (3s.f.)we have 2 values for t:−0.06 and 4.06.
since time cannot be negative, only the positive value can be taken.
this is 4.06, to 3 significant figures.the time taken is 4.06 seconds.

The two tables give the number of pints of red and blue paint that are used to make different amounts of two shades of purple paint.
Purple #1 is made by mixing red and blue in a ratio of 1 : 2.
Purple #2 is made by mixing red and blue in a ratio of 1 : 3.
Use the drop-down menus to complete each sentence below.
The combine ratios will be a1:a2:a3 = 1:2:3 as the a1 is equal to a2 and the 2:4 shows the mixing 2 red with 4 blue paint.
What is the ratio?It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign : between the numbers.
We have:
Purple 1 is made by mixing red(a1) and blue(a2) in a ratio of 1 : 2.
Purple 2 is made by mixing red(a3) and blue(a4) in a ratio of 1 : 3.
Here the options are not given, but we can combine the above ratios like:
a1:a2:a3 = 1:2:3 (a1 = a3)
If we multiply with any number (let's say 2) in the ratio 1 : 2 and 1 : 3
We get:
2:4 (mixing 2 red with 4 blue paint) and
2:6 (mixing 2 red with 6 blue paint)
Thus, the combine ratios will be a1:a2:a3 = 1:2:3 as the a1 is equal to a2 and the 2:4 shows the mixing 2 red with 4 blue paint.

A large pizza costs $18. Each topping costs an additional $2.25, and each side
costs an additional $2.50.
Part A: Write an expression to represent the cost of a large pizza with
t toppings and s sides.
Part B: What is the cost of buying a large pizza with 2 toppings and 3 sides?
Answer:
Part A: total pizza cost = 2.50s + 2.25t + 18
Part B: 30 dollars
Step-by-step explanation:
I hope this helped! If it did, please click "Thanks"!
Answer:
Part A: 18 + 2.25t + 2.50s
Part B: $30
Step-by-step explanation:
Let t= each additional topping
Let s=each side
First we add the cost of one pizza ($18)
Then we add each additional topping (t) multiplied by its cost (2.25 dollars)
Finally we add each side (s) multplied (2.50 dollars)
Part B:
Plug in 2 for t and 3 for s into the expression from earlier and simplify:
Expression: 18 + 2.25(2) + 2.50(3)
=18+ 4.50 + 7.50
=30
And there you have it- the total cost is $30.
Hope this helps and good luck in your studies :)
find the area of the following figure
Answer:
C) 312 cm^2
Step-by-step explanation:
To find the total area of the composite figure, you must sum the individual components of the figure.
First, we find the area of the rectange, which is A = l x w = 16 x 12 = 192
Second, we find the area of the first triangle which is also equal to the area of the second triangle, so instead of finding the base times height and dividing by 2, we will simply find the area of base times height and it will work for both trianges.
A = b x h x 1/2 x 2 = 10 x 12 = 120
120 + 192 = 312 cm^2
