Find the x-intercepts for the parabola defined
Inessa05 [86]

Answer:

<h2>Explanation:</h2>

In this exercise we have the following equation of a parabola:

y=2x^2-12x+10

So our goal is to find the x-intercepts. We can find this setting y=0, so:

2x^2-12x+10=0

Taking 2 as common factor:

2(x^2-6x+5)=0

Hence this is a Non-perfect Square Trinomial. To factor out this, let's choose two numbers such that:

  • The sum is -6
  • The product is 5

Those two numbers are:

  • -1 and -5

Because:

  • Sum: -6
  • Product: 5

So this equation can be written as:

x^2 + (a + b)x + ab=(x + a)(x + b) \\ \\ a=-1 \\ b=-5 \\ \\  x^2-14x+24=(x-(-1))(x-(-5))=0 \\ \\ (x+1)(x+5)=0 \\ \\ So \ the \ solutions \ are: \\ \\ \boxed{x=-1 \ and \ x=-5}

Elena-2011 [213]

Answer:

4x + 8y = 50 or 4x + 8y > 50

Step-by-step explanation:

To find which equation show the exact answer, Becasue he need at least 50 poitns to have a B, so:

4x + 8y must larger or equal to 50

In these choice, some I can't figure out what it means but the correct answer for this is:

4x + 8y = 50 or 4x + 8y > 50

Hope this help you :3

The average cost of online photos decreased
SCORPION-xisa [38]

Answer:

The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year

Step-by-step explanation:

Given that

Price of print in 2002 = p1 =$0.50

Price of print in 2013 = p2 =$0.13

y1 = 2002

y2 = 2013

The rate of change is given by the formula:

r = \frac{decrease}{run}

Here decrease is the change in price and run is the difference in years.

Mathematically, it can be written as:

r = \frac{p_2-p_1}{y_2-y_1}

Putting the values

r =\frac{0.13-0.50}{2013-2002}\\r = \frac{-0.37}{11}\\r =-0.0336\\r = -0.034

Hence,

The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year

AURORKA [14]

Answer:

11.2 cm

Step-by-step explanation:

Given that;

Arc Length Formula (if θ is in radians): l = ϴ × r

ϴ = angle subtended in radians

r= radius of the circle

l = 8cm × 1.4 radians

l= 11.2 cm
