Graph the following function and identify any shifts, stretches, and symmetry and x and y intercepts:
klasskru [66]

Shifts:

Shifted three units right and two units up to match the blue parabola

Stretches:

It doesn't have any stretches

Symmetry:

x=3

x and y intercepts:

x intercpets: It has no x-intercepts

y-intercepts: (0, 11)

<h2>Explanation:</h2>

The pattern of the quadratic function is:

f(x)=x^2

Whose graph is shown below as the red parabola.

So here we need to identify some characteristics of:

y = f(x) = (x - 3)^2 + 2

Whose graph is shown below as the blue parabola.

As you can see, the blue parabola is a transformation of the red parabola. The rule is as follows:

  • The red parabola has been shifted three units right and two units up to match the blue parabola.

This is so because, for any function:

y=f(x)

We have the following transformations:

y=h(x)=f(x+c)+k \\ \\ \\ \bullet \ c>0 \ Shift \ f(x) \ c \ units \ to \ the \ left \\ \\ \bullet \ c0 \ Shift \ f(x) \ k \ units \ up \\ \\ \bullet \ k

On the other hand, the blue graph has neither stretches nor x intercepts. Finally, its axes of symmetry is x=3. The y-intercept is (0, 11) is indicated in the figure.

The height of a ball dropped from the top of a 450-foot tall building can be described by the expression
BaLLatris [955]

Answer:

The answer is 386 feet.

Step-by-step explanation:

This equation simply asks to plug in a value that gives you the final value of the height. 450 is the initial height, and r (or l) is referred to as the amount of seconds after the item is dropped. 16 is the constant value of feet that the ball drops within one second.

Therefore, by substituting 4 for r (or l) and multiplying it by 16, you will receive 64 feet in 4 seconds. Finally, you need to subtract this from 450 feet, giving you a final answer of 386 feet.

A is a finite non-empty set. The domain for relation R is the power set of A.(Recall that the power set of A is the set of all s
siniylev [52]

Answer:

The answer is "Choice D"

Step-by-step explanation:

Determining the information:

For "X \subseteq A " and "Y \subseteq A",  X relates to Y when X and Y has the same cardinality. therefore, R does not have reflective:

For every "X \subseteq A", "X= X" So, X  not proper subset ofX.  So, R does not havereflexive.

R does not have symmetry:

For every "X \subseteq Y" ,then, "Y \subset X"  is not true because X not relate to Y.  So, R is not symmetric.

R does not have antisymmetric:

When X relates to Y and Y is relate to X, then "X \subset Y" and "Y \subset X"\to X=Y

Therefore, R is anti-symmetric.

A total of 600 advertisements were sold for a certain magazine. If 30 percent of the first 200 sold were in color, 20 percent of
solong [7]

Answer:

%35 of them were in color

Step-by-step explanation:

Since 30 percent of the first 200 sold were in color, 200x30/100 = 60 of them were in color.

Since 20 percent of the next 300 sold were in color, 300x20/100 = 60 of them were in color.

Since 90 percent of the last 100 sold were in color, 100x90/100 = 90 of them were in color.

In total, 60 + 60 + 90 = 210 out of 600 were in color.

The percentage is:  \frac{600}{100} = \frac{210}{x} → x = \frac{21000}{600} = 35
