Write the equation of the parabola in vertex form.
vertex (1,3), point (2, - 1)
Answer:
[tex]y=-4x^2+8x-1[/tex]
Step-by-step explanation:
I am assuming the parabola has his axis parallel to the y axis. You should remember from theory that the axis (and thus the first coordinate of the vertex) is [tex]-\frac b{2a}[/tex] and then you have two points of passage.
[tex]-b/2a = 1\\a(1)^2 +b(1)+c =3\\a(2)^2+b(2)+c=-1\\[/tex]
Let's solve subtracting the 3rd from the second and keeping the first as is (ok, slightly rewriting it).
[tex]2a=-b\rightarrow 2a+b =0 \\a+b+c=3\\4a+2b+c=-1\\III-II: 4a+2b+c-a-b-c=-1-3 \rightarrow 3a+b=-4 \rightarrow a +(2a+b)=-4\\a= -4; b=8; c =3 +4 -8 =-1[/tex]

Questions 7-10: Johnny sister, Jamila, sells chocolate candy bars. Her profit is represented by the function
M(x) = 3x – 20, where M(x) represents the money made after x number of candy bars have been sold.
7. How many candy bars would Jamila have to sell to begin making money (meaning that she makes $1)?
Answer:
the answer is 7 candy bars
Step-by-step explanation:
theres two ways of doing this the equation way and the common sense way m(x) basically just means y so y= 3x -20 we can set y to 0 so 0 = 3x -20 next add 20 to the other side 20 = 3x then divide both sides by 3 you get x= 6.666 but you cant sell .666 of a chocolate bar so round to 7 and thats your answer. the other strategy is saying hey i get $3 per candy bar what number would put be at 21 since 21-20= $1 and we say 7*3 = 21 so 7 is the answer.
The graph y=e^x is transformed as shown in the graph blow which equation represents the transformed function ?
Answer:

Step-by-step explanation:
y=e^x will go through (0,1). Since it goes through (0,4), then the function moves up 3 units. So we need to add 3 after e^x
You purchase a birthday gift for $105.00. You recall the tag above the gifts to read $175.00 as a retail price. You are pleasantly surprised at the discount that you had not seen. What was the percentage of discount offered on your gift? i assume the answer will be 70%?
We then swap this around for the lower number that equals to 100.
100-60= 40
40%
I hope this is helpful.
Answer:
If the retail price was $175.00, and you purchased this item for $105.00, then the discount was 40%
Step-by-step explanation:
[tex]\frac{105}{175} = \frac{21}{35}= \frac{3}{5} = 0,6[/tex] - that means you paid 60% out of the total price
the discount however is not the percentage that you paid, but the X% OFF, so in that case:
[tex]100 - 60 = 40[/tex]
The discount on this item was 40%
What's the answer to (10x+200)
u Estimate the amount of the tip by rounding the bill to the nearest ten dollars before calculating. 20% tip on a bill of $123.42 The amount of the tip is approximately $
Answer:
Tip formula
In general, the tip amount is the cost times 0. xx and your total including tip, is the cost times 1. xx where xx = the percent you want to leave. If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.

If the output and input of a linear equation are proportional, where will the graph of the equation cross the x-axis?
If the output and input of a linear equation are proportional, the graph of the equation cross the x-axis at (0, 0).
What are proportional functions?In any function, the amount of one quantity is dependent on the amount of another. All proportional functions use a rate in the same way. We call the rate the constant of variation, or the constant of proportionality. It’s a constant because this number does not change within the function. Because the input and output are linked by a constant, changes in the independent variable cause the dependent variable to change in a proportional, steady way.
y ∝ x
⇒ y = kx
where k is the constant of proportionality.
For the graph of this function to cross x axis, y = 0
When y = 0 and k is some non zero constant value, x = 0
Thus, the coordinate at which the graph of the function crosses x axis is (0, 0).

find the area of 20mm 14mm 32mm
Answer:
42 is an area
Step-by-step explanation:
The area of a trapezium.
= 1/2 x (a + b) x h
Where a and b are the two parallel sides.
The area of a semicircle.
Area of a circle = πr²
Area of the semicircle = 1/2 x πr²
The area of20mm 14mm 32mm is 521 mm²
What is a circle?
A circle is a two-dimensional figure with a radius and circumference of 2 x pi x r.
The area of a circle is given as:
Area = πr²
We have,
Figure:
The figure is a combination of a trapezium and a semicircle.
The area of a trapezium.
= 1/2 x (a + b) x h
Where a and b are the two parallel sides.
a = 32 mm
b = 20 mm
h = 14mm
= 1/2 x (32 + 20) x 14
= 52 x 7
= 364 mm²
The area of a semicircle.
Area of a circle = πr²
Area of the semicircle = 1/2 x πr²
Diameter = 20 mm
Radius = 20 / 2 = 10 mm
= 1/2 x π x 10²
= 1/2 x 3.14 x 10 x 10
= 3.14 x 10 x 5
= 157 mm²
Now,
The area of the figure.
= area of trapezium + area of semicircle
= 364 + 157
= 521 mm²
Thus,
The area of20mm 14mm 32mm is 521 mm²
