Answer:
[tex]y=3(x-2)^2[/tex]
Step-by-step explanation:
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola, and a is a coefficient different from zero.
We are given the vertex located at (2,0). The equation is now:
[tex]y=a(x-2)^2+0[/tex]
[tex]y=a(x-2)^2[/tex]
Since we know the point (1,3) is on the parabola:
[tex]3=a(1-2)^2[/tex]
3=a(1)
a = 3
Finally, the quadratic equation is:
[tex]\mathbf{y=3(x-2)^2}[/tex]

2/3x-1/5>1 x=?
Answer:
x>9/5
Step-by-step explanation:
2/3x-1/5(+1/5)>1(+1/5)
[add 1/5 on both sides]
2/3x (÷3/2)>6/5 (÷3/2)
[flip 2/3 to 3/2 so that they cancel out]
x>9/5
PLZZZZ HELP Write 512 as a product of primes use index notation
Answer:
[tex]\mathbf{512 = 2 \times 2 \times 2\times 2\times 2\times 2\times 2\times 2\times 2}[/tex]
Step-by-step explanation:
Prime numbers are those numbers in which they can be divided by itself and 1. They are formed by two natural numbers higher than 1 but not by multiplying natural numbers that are smaller.
So; using index notation to writing 512 as a product of primes; we have:
[tex]\mathbf{512 = 2 \times 2 \times 2\times 2\times 2\times 2\times 2\times 2\times 2}[/tex]
Liza wants to have more than $750 in her
savings account before she will leave for college.
Right now she has $300, and she is going to
baby sit to earn $ 12.00 an hour. How many hours
will Liza need to babysit before she leaves for
college? What’s the inequality
Answer:
x is equal to or greater than 38.
Step-by-step explanation:
use the equation 300+12x to find the amount of money in total dependent on x, the number of hours she worked.
Step-by-step explanation:
750-300= $450 left that needs to be save to meet her goal.
set an equation to equal 450 that includes the next part of the information given which is $12 and hour
450=12x
isolate x by dividing 12 to both sides
x= 37.5 hrs
the inequality could be :
750<_ 300+ 12x

How many cubic meters of water are required to fill a rectangular swimming pool 15m long and 10 m wide which is 2m deep throughout.How many liters is that?
Answer:
300,000 liters
Step-by-step explanation:
Let us have the measurements in cm
100 cm = 1 m
so the measurements are multiplied by 100
we have this as;
1500 by 1000 by 200
The volume is the product of the 3
This is :
1500 * 1000 * 200 = 300,000,000 cm^3
Mathematically, 1 liter = 1000 cm^3
300,000,000 cm^3 will be ;
300,000,000/1000 = 300,000 liters

graph a line that contains the point (3,-6) and has slope of -1/2
Answer:
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y intercept
Since, m = -[tex]\frac{1}{2}[/tex]
Equation of the line will be,
y = [tex]-\frac{1}{2}x+b[/tex]
Since, a point (3, -6) lies on the line,
-6 = [tex]-\frac{3}{2}+b[/tex]
b = -6 + 1.5
b = -4.5
Equation of the line will be,
[tex]y=-\frac{x}{2}-\frac{9}{2}[/tex]
Table for the points on the graph,

9. Factorize: 6x2 - 19x + 14.
Answer:
Step-by-step explanation:
Here, we want to factor the given polynomial
We have this as;
6x^2 - 19x + 14
= 6x^2 -12x-7x + 14
= 6x(x-2) -7(x-2)
= (6x-7)(x-2)
6x^2-19x + 14 = (6x-7)(x-2)
