Suppose the equation of the axis of symmetry for a quadratic function is x = -1 and one of the x-intercepts is 7. What is the other x-intercept?

Answers

Answer 1

The graph of a quadratic function is a parabola.
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Taking into account the definition above, then the other intersection with x will be:
horizontal distance between the axis of symmetry and intersection with x:
d = 7 - (- 1) = 7 + 1 = 8
The second intersection will then be:
x2 = -1-8 = -9

Answer:
the other x-intercept is:
x2 = -9

Match each angle measure in degrees with its equivalent measure in radians

Answers

To convert angle from radian measure to degree measure, multiply it by 180/π.

So,
a) 5π/4 in degree measure will be:

[tex] \frac{5 \pi }{4}* \frac{180}{ \pi } = 225[/tex]

So, 5π/4 radian is equal to 225°.

b) 9π/5 in degree measure will be:

[tex] \frac{9 \pi }{5}* \frac{180}{ \pi } = 324 [/tex]

So, 9π/5 radian is equal to 324°.

c) 2π/3 in degree measure will be:

[tex] \frac{2 \pi }{3}* \frac{180}{ \pi } = 120[/tex]

So, 2π/3 radian is equal to 120°.

d) 4π/9 in degree measure will be:

[tex] \frac{4 \pi }{9}* \frac{180}{ \pi } = 80[/tex]

So, 4π/9 radian is equal to 80°.

e) 5π/6 in degree measure will be:

[tex] \frac{5 \pi }{6}* \frac{180}{ \pi } = 150[/tex]

So, 5π/6 radian is equal to 150°.

f) 7π/4 in degree measure will be:

[tex] \frac{7 \pi }{4}* \frac{180}{ \pi } = 315[/tex]

So, 7π/4 radian is equal to 315°.

Rules that govern the ways that logarithms are simplified and combined are going to be very similar to simplifying and combining rules for what other family of functions?

Exponential
Linear
Rational
Polynomial

Answers

They are going to be very similar to rules governing exponential functions. This is due to the fact that logarithms in essence "cancel" exponents.

Rules that govern the ways that logarithms are simplified and combined are going to be very similar to simplifying and combining rules for the exponential family of function.

This comes from the definition of logarithm itself which says that a logarithm is a quantity representing the power to which a fixed number (the base) must be raised to produce a given number.

Let us illustrate this by way of an example. We know that 100 can be represented as [tex] 10^2 [/tex]. Here 10 is the base, 2 is the power and 100 is the given number. Therefore,

[tex] 10^2=100 [/tex]

Likewise, we can represent 1000 as [tex] 1000=10^3 [/tex]

Now, if we multiply [tex] 10^2 [/tex] and [tex] 10^3 [/tex] we will get: [tex] 10^2\times 10^3=10^{2+3}=10^5 [/tex]. We added the powers. Therefore, the logarithm of [tex] 10^5 [/tex] to the base 10 is 5.

Let us see if we will get the same result by using the rules of logarithms.

[tex] log(10^2\times 10^3)=log(10^2)+log(10^3)=2log(10)+3log(10)=2+3=5 [/tex]

As we can see we got the same result by using the logarithm and the exponential rule, thus, verifying our answer. Similar results can be obtained for other operations of the logarithmic rule.

What is the vertex of the graph of y = x2 + 4x?
(–2, –12)
(–2, –8)
(–2, –6)
(–2, –4)

Answers

the answer is (-2,-4)

Answer:

(-2, -4)

Step-by-step explanation:

Let's remember how to calculate the vertex of a parabola:

If we have the equation of the parabola given in the form y = ax^2 + bx + c, the x-coordinate of the vertex is x = -b/2a. For the y-coordinate we just replace the x of the equation with -b/2a and do the calculation.

In this case, a = 1, b = 4, c = 0.

The x-coordinate of the vertex is x = -4/2*1 = -2

The y-coordinate is y = (-2) ^2 + 4*(-2) = 4 - 8 = -4

Therefore, the vertex is (-2, -4)

Galileo wanted to release a wooden ball and an iron ball from a height of 100 meters and measure the duration of their fall. He found a plane with an incline of 12 degrees that he could climb until he could get to an altitude of 100 m. How far should Galileo walk up the inclined plane? Round your final answer to the nearest hundredth.

Answers

For this case what you have is the same as a rectangle triangle where you have as data the degree of inclination of the hypotenuse with respect to the base and the height of the triangle.
We have to find the value of the hypotenuse.
For this we use the following trigonometric relationship:
senx = C.O / h
Where
x: angle
C.O: opposite leg
h: hypotenuse.
Substituting the values we have:
sen (12) = 100 / h
We cleared h:
h = 100 / sin (12)
h = 480.97 m
Answer:
Galileo should walk 480.97 m up the inclined plane

Galileo walk 480.97 meters up the inclined plane if Galileo wanted to release a wooden ball and an iron ball from a height of 100 meters and measure the duration of their fall.

What is the trigonometric ratio?

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

We have:

Galileo wanted to release a wooden ball and an iron ball from a height of 100 meters.

Let's suppose Galileo walked x meters up the inclined plane.

The plane with an inclined a 12°

As we can see in the right angle triangle the sin ratio:

[tex]\rm sin24\° = \frac{100}{x}[/tex]

[tex]\rm x = \frac{100}{sin24\°}[/tex]

x = 480.97 meters (Sin12° = 0.20791)

Thus, Galileo walk 480.97 meters up the inclined plane if Galileo wanted to release a wooden ball and an iron ball from a height of 100 meters and measure the duration of their fall.

Describe the correlation between the score and time spent studying.

Answers

There appears to be a positive correlation between the number of hour spent studydng and the score on the test.

When identifying the independent and dependent quantities, we think about what would cause the other to change. The score on the test would not cause the number of hours spent studying to change; rather, the number of hours spent studying would cause the score to change. This means that the number of hours studying would be the independent quantity and the score would be the dependent quantity.

Plotting the graph with the time studying on the x-axis (independent) and the score on the y-axis (dependent) gives you the graph shown. You can see in the image that there seems to be a positive correlation; the data seem to generally be heading upward.

As per the table, the given science scores and time data for studying about 10 hours are given.

A positive correlation can be seen between the number of hours spent studying and the scores. This states that the no. of hours of studying could be on the independent and the score would be the dependent quantity. When on the graph with the time studying on the x-axis and the y-axis gives you the graph the line seems to be going up hence a positive correlation.

There are seven black marbles and nine white marbles in a bag what is the aprroximate probability of drawing two black marbles and then a white marble without replacement

Answers

There are a total of 16 marbles in the bag. Black marbles compound 7/16 or 43.75% of the bag. White marbles compound 9/16 or 56.25% of the bag.

There is a probability of 43.75% to pick a black marble in the bag with 16 marbles.
If you do , there will be 6 black marbles and 9 white marbles left in the bag. The probability to pick anpther black marble is 6/15 or 40%.

If you do pick another black marble , there will be 5 black marbles and 9 white marbles left in the bag , which means the probability of you getting a white marble next is 9/14 or 64.28%.

Now we just have to multiply the probability of you picking the marbles in the right order :

0.4375 × 0.4 × 0.6428 = 0.11249

Which is approximately 11.25%

The approximate probability of drawing two black marbles and then a white marble without replacement is 9/80.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

Number of black marbles = 7

Number of white marbles = 9

The event of drawing two black marbles from seven black marbles is

⇒ [tex]\frac{7C_{2} }{16C_{2} }[/tex]

[tex]7C_{2} =\frac{(7)(6)}{(1)(2)}[/tex]

⇒ 21

[tex]16C_{2}=\frac{(16)(15)}{(1)(2)}[/tex]

⇒ 120

Now, [tex]\frac{7C_{2} }{16C_{2} }=\frac{21}{120}[/tex]

Total number of balls, after drawing 2 black balls without replacement is

⇒ 16 - 2 = 14

The event of drawing a white marble without replacement from nine white marbles is

[tex]\frac{9C_{1} }{14C_{1} } = \frac{9}{14}[/tex]

Thus, the approximate probability of drawing two black marbles and then a white marble without replacement is

P(E) = [tex](\frac{21}{120}) (\frac{9}{14} )[/tex]

⇒ 9/80

Hence we can conclude that the approximate probability of drawing two black marbles and then a white marble without replacement is 9/80.

First off, we can rule out that this is not an arithmetic sequence, as the y values do not have a common difference.
Next, let's look at the y values again, and test out the common ratios given. First, let's use 0.6. If it's a common ratio of 5, 3, 1.8, and 1.08, then we can find that out by multiplying it by 5 first.
5 x 0.6 is 3.
Then, 3 x 0.6 is 1.8.
Finally, 1.8 x 0.6 is 1.08.
Therefore, B is correct. The table represents a geometric sequence because the successive y-values have a common ratio of 0.6, since multiplying the values by 0.6 equals the next value down.
