The graphs below are both quadratic functions. The equation of the red graph is
Natali5045456 [20]

Answer:

D. g(x)=\frac{1}{5}x^2

Step-by-step explanation:

  • The equation of the red quadratic graph is f(x)=x^2.
  • This is the parent quadratic function or the base of the quadratic functions.
  • This red quadratic graph has been dilated by a certain scale factor  to obtain the blue graph. Recall that, when the scale factor is a fraction, such that 0\: the graph is stretched horizontally.
  • The dilated graph then becomes wider than the parent function.
  • From the given function equations, the possible value of k can only be k=\frac{1}{5}.
  • Therefore the blue graph has equation: g(x)=\frac{1}{5}x^2
  • The correct answer is D.

I’m confused on this one
sammy [17]

The angles that form similarity are those that are vertically opposite and 2 pairs that are equal because the for a Z formation.


Since <LPM = <ONM then


\dfrac{LP}{NO}=\dfrac{LM}{MO}\\ \\\dfrac{5x - 10}{4x-9}=\dfrac{16}{12} Cross multiply

12*(5x - 10) = 16*(4x - 9) Remove the brackets on both sides.

60x - 120 = 64x - 144 Subtract 60x from both sides.

- 120 = 64x - 60x - 144

-120 = 4x - 144 Add 144 to both sides.

-120 + 144 = 4x

24 = 4x Divide by 4

24/4 = x

x = 6

The price of one gallon of milk has increased from $3.24 to $4.05. What is the percentage increase?
Alisiya [41]
Let initial price be = x = 3.24
final price = y = 4.05
Difference = 4.05 - 3.24
= 0.81
Percentage increase = 0.81 / 3.25 × 100
= 25 %
