Answer:

<u>f(x) = x² - 4x + 2 or f(x) = (x - 2)²</u>

Step-b<u>y</u>-step explanation:

  • The parabola touches the x-axis at only one point
  • If we use y = a(x − h)² + k, we can see from the graph that h = 2 and k = 0
  • This gives us y = a(x − 2)²

What is the value of "a"?

  • We also see that the y-intercept is (0, 4)
  • We can plug it into the equation
  • 4 = a(0 - 2)²
  • 4a = 4
  • a = 1

<u>So, our quadratic equation will be</u> :

  • y = 1(x - 2)²
  • <u>y = x² - 4x + 2 or y = (x - 2)²</u>

Answer: x= 2.5, y = 10

Step-by-step explanation:

<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>

If they're proportional, you can set up two proportions:

1) \frac{x}{5} =\frac{3}{6} \\\\2) \frac{5}{y} =\frac{3}{6}

And cross-multiply:

1) 6x = 5*3 \\\\2) 3y = 5*6

Then solved for x and y:

1) 6x = 15\\x=\frac{15}{6} =\frac{5}{2} =2.5 \\\\2) 3y = 30\\y=\frac{30}{3} =10

mote1985 [20]
The height of the plant is given by the equation h = 0.5d + 4. Rewrite this as a function rule where f(x) is the height, in centimeters, and x is the time, in days. Use the rule to complete the table, and then use the drawing tools to create the graph representing this relationship.

Please help me answer number 38.
julia-pushkina [17]

The request is to find the intersection of the two sets. By definition, the intersection of two sets is another set, composed by all the elements appearing in both sets.

In other words, P\cap Q is the set of all elements that P and Q have in common.

P contains all the numbers from 0 to 9, V contains all the odd numbers between 1 and 19. So, their intersection will be the odd numbers between 0 and 9, i.e.

P\cap Q=\{1, 3, 5, 7, 9\}
