3. A quadratic relation has an equation of the form = ( − )( − ). Determine the value of
when:
a) the parabola has zeros at (4,0) and (2,0) and a y – intercept at (0,1)
b) the parabola has x – intercepts of (4,0) and (-2,0) and a y – intercept at (0,-1)
c) the parabola has zeros at (5,0) and (-3,0) and a minimum value of -10.
Answers
Answer:
Step-by-step explanation:
a) y = a(x - 4)(x - 2)
x = 0, y = 1, so 1 = a(-4)(-2) = 8a, a = 1/8
so y = (x - 4)(x - 2)/8
b) y = a(x - 4)(x + 2)
x = 0, y = 1, so 1 = a(-4)(2) = -8a, a = -1/8
so y = -(x - 4)(x + 2)/8
c) y = a(x - 5)(x + 3)
y = a(x² - 2x - 15) = a(x² - 2x + 1 - 16) = a[(x - 1)² - 16]
when x = 1, y has a minimum value -16a
so -16a = -10, a = 5/8
so y = 5(x - 5)(x + 3)/8

How far is lakeview from avon
Answers
Answer:
They are about 45.19 miles apart.
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem,
a² + b² = c²
-> c is the hypotenuse, a and b are both legs (the other two sides)
a² + b² = c²
19² + 41² = c²
361 + 1,681 = c²
2,042 = c²
[tex]\sqrt{2,042}[/tex] = c
45.19 miles ≈ c
c ≈ 45.19 miles
They are about 45.19 miles apart.

What is a right-angle triangle?
An isosceles triangle, which consists of a pair of sides as well as sides with angles identically, is additionally recognized as a right triangle. Two 45° angles and a 90° angle make up a right isosceles triangle. The triangle's three sides add up to 180 degrees in total.
The information that is provided is with respect to the right triangle:
Side 1 is given as = 9
Side 1 is given as = 12
Applying the Pythagoras theorem:
[tex]H^{2} = S1^{2} + S2^{2} \\= 9^{2} + 12^{2} \\\\= 81 + 144\\=225\\h = \sqrt{225} \\h = 15[/tex]

Find the distance between 3 3/8
and −4 5/8
on a number line. Write your answer in simplest form.
Answers
Answer:
8
Step-by-step explanation:
The distance can be found by subtracting the left number from the right number:
(3 3/8) -(-4 5/8) = (3 3/8) +(4 5/8)
= (3 +4) +(3/8 +5/8) = 7 + 8/8
= 8
The distance between the points is 8 units.
The phone company offers Rachel 12c per minute for her long distance calls. A discount company called Rachel and offered her long service for 1/2c per minute, but will charge a R46 monthly fee. How many minutes per month must Rachel talk on the phone to make the discount a better deal?
Answers
Step-by-step explanation:
x = number of minutes
the cost function (in c) of the phone company is
cp(x) = 12x
and the cost function of the discount company is
cd(x) = x/2 + 4600 (R46)
we now need to calculate for what x this becomes the same cost :
12x = x/2 + 4600
24x = x + 9200
23x = 9200
x = 400 minutes
she would have to talk for at least 400 minutes long distance per month to make it an even or then better deal.
with 400 minutes being the break-even point.
so, to make it a better deal (not just equal), she has to talk for at least 401 minutes per month.

What is the value of x?
Answers
Answer:
12
Step-by-step explanation:
(10x - 20) + (6x + 8) = 180
16x - 12 = 180
16x = 192
x= 12
Hi there!
This is an example of supplementary angles, angles that sum up to 180° (they form a straight line).
Summing these two angles up equals 180°, so:
180° = (10x - 20)° + (6x + 8)°
We can drop the ° sign for ease of solving.
180 = 10x - 20 + 6x + 8
Combine like terms:
180 = (10x + 6x) - (20 + 8)
180 = 16x - 12
Add 12 to both sides:
192 = 16x
Divide both sides by 16:
192/16 = 16x/16
x = 12°
10-(3x-1)/2=(6x+3)/11
If someone could help that would be great thank you!
Answers
If it is :
[tex]10 - \frac{ (3x - 1)}{2} = \frac{(6x + 3)}{11} \\ [/tex]
Multiply both sides by 22
[tex](22 \times 10) - 11 \times (3x - 1) = 2 \times (6x + 3) \\ [/tex]
[tex]220 - 33x + 11 = 12x + 6[/tex]
[tex] - 33x + 231 = 12x + 6[/tex]
Plus both sides 33x
[tex]231 = 33x + 12x + 6[/tex]
[tex]231 = 45x + 6[/tex]
Subtract sides minus 6
[tex]231 - 6 = 45x[/tex]
[tex]45x = 225[/tex]
Divided sides by 45
[tex]x = \frac{225}{45} \\ [/tex]
[tex]x = 5[/tex]
_________________________________
If it is :
[tex] \frac{10 - (3x - 1)}{2} = \frac{6x + 3}{11} \\ [/tex]
Multiply sides by 22
[tex](11 \times 10) - 11 \times (3x - 1) = 2 \times (6x + 3) \\ [/tex]
[tex]110 - 33x + 11 = 12x + 6[/tex]
[tex] - 33x + 121 = 12x + 6[/tex]
Plus sides 33x
[tex]121 = 12x + 33x + 6[/tex]
[tex]121 = 45x + 6[/tex]
Subtract sides minus 6
[tex]121 - 6 = 45x[/tex]
[tex]45x = 115[/tex]
[tex]x = \frac{115}{45} \\ [/tex]
[tex]x = \frac{23}{9} \\ [/tex]
