Answer:

(0,6) and (-2, 0)

Step-by-step explanation:

All straight lines follow the equation, y = mx + c. where c is the y-intercept (the point where the line meets the y-axis) and m is the gradient.

In this equation, c = 6. So, the point where the line meets the y-axis is (0, 6).

Remember: the point where the line meets the y-axis always has an x-coordinate of 0 and the point where the line meets the x-axis has a y-coordinate of 0.

using this information, we can substitute y in the equation with 0 becoming

0 = 6 + 3x

now we can solve for x.

0 -6 = 3x

-6 / 3 = x

x = -2

the coordinate is (-2, 0)

The measure of the angles m∠1 and m∠2 for the polygon are 72° and 54° respectively.

To calculate the sum of interior angles of a polygon, you can use the following formula:

Sum of interior angles = (n-2) x 180 degrees

Where "n" represents the number of sides (or vertices) of the polygon.

Given the 5 sided polygon;

(5 - 2) × 180 = 540

one interior angle = 540/5 = 108°

m∠2 = 108°/2

m∠2 = 54°

m∠1 = 180 - [2(54°)]

m∠1 = 180 - 108

m∠1 = 72°

Therefore, the measure of the angles m∠1 and m∠2 are 72° for the polygon and 54° respectively.

Answer:

\(m = -3\)

Step-by-step explanation:

-To determine the slope of the red line on the graph, you need the slope formula:

\(m = \frac{y_{2} - y_{1}}{x_{2}- x_{1}}\)

-Since the red line shows it's decreasing, then the number will be negative.  So, l picked \((0,3)\) and \((1,0)\) for the slope formula:

\(m = \frac{0 - 3}{1 - 0}\)

Then, solve:

\(m = \frac{0 - 3}{1 - 0}\)

\(m = \frac{-3}{1}\)

\(m = -3\)

so, the slope is \(-3\).

Answer:

To factor 4x³-10x²-14x, we can first factor out the greatest common factor, which is 2x:

4x³-10x²-14x = 2x(2x² - 5x - 7)

Next, we can factor the quadratic expression 2x² - 5x - 7 using either factoring by grouping, completing the square, or the quadratic formula. Here, we'll use factoring by grouping:

2x² - 5x - 7 = 2x² - 7x + 2x - 7

= (2x² - 7x) + (2x - 7)

= x(2x - 7) + (2x - 7)

= (2x - 7)(x + 1)

Therefore, the factored form of 4x³-10x²-14x is:

4x³-10x²-14x = 2x(2x - 7)(x + 1)

Answer:

  an = 1/2n² -1/2n -2

Step-by-step explanation:

You want a formula for the n-th term of the quadratic sequence -2, -1, 1, 4.

Using x = 1, 2, 3 and y = -2, -1, 1 we can write equations for the coefficients a, b, c of the quadratic expression ax² +bx +c.

  a(1²) +b(1) +c = -2

  a(2²) +b(2) +c = -1

  a(3²) +b(3) +c = 1

Subtracting the first equation from the other two, we get ...

  3a +b = 1

  8a +2b = 3

Subtracting twice the first from the second of these, we get ...

  (8a +2b) -2(3a +b) = (3) -2(1)

  2a = 1

  a = 1/2

Then b can be found from ...

  b = 1 -3a = 1 - 3/2 = -1/2

And c can be found from ...

  -2 -b -a = c = -2 -(-1/2) -(1/2) = -2

The formula is ...

  an = 1/2n² -1/2n -2

__

Additional comment

For systems of equations, the solver used in the second attachment works well. It tells us (a, b, c) = (1/2, -1/2, -2) as we found above.

Alternate solution

The first differences of the given terms are ...

  1, 2, 3

And their differences are ...

  1, 1

The coefficient of n² is half this second-difference value: 1/2.

If you subtract 1/2n² from the given terms, you get ...

  -5/2, -3, -7/2, -4

This arithmetic sequence has the formula ...

  a1 +d(n -1)

  -5/2 +(-1/2)(n -1) = -1/2n -2

Adding this to the term we subtracted gives ...

  an = 1/2n² -1/2n -2 . . . . . as above

An important measure of location for categorical data is the mode.

While the mean and median can only be determined for numeric data, the mode can be used to describe categorical variables. The mode's principal benefit as a gauge of central tendency is this. When continuous or discrete variables are expressed as intervals, it is also helpful.

The mode represents the value that occurs most often in a dataset.

A dataset can have no mode (if no value repeats), one mode, or multiple modes.

A set of data values' mode is the value that appears the most frequently. The value x (i.e., X = x) at which the probability mass function takes its maximum value is known as the mode if X is a discrete random variable. In other words, it is the value that will be sampled most frequently.

First of all, we have a lot of different forms of part/whole's. We have a fraction, a percentage, and a number. How do we make this work???

Let's convert our percent and fraction to ounces, because that is what the question is talking about.

1/5 of 20

1/5=x/20

20=5x

/5      /5

4=x

Now lets convert our percent into ounces.

30% of 20

30/100=x/20

30(20)=100x

600=100x

/100  /100

6=x

Now we have our ounces, we now need to find what is the granola. To do that, we need to add the number of everything else, and then subtract that by the total ounces.

4+6+5=15

The probability of a randomly selected person being left-handed is 0.117. Using this information, the expected number of left-handed pitchers in a group of 630 can be determined using the formula:

Expected Value = (Probability of Event) * (Number of Trials)

Expected Value = (0.117) * (630)

Expected Value = 73.31

To administer 1 gram of the medication, you would need to give approximately 1.714 milliliters.

To determine the number of milliliters to administer in order to give 1 gram of medication, we need to convert the units appropriately.

Given that the medication is available in 350,000 micrograms per 0.6 ml, we can set up a proportion to find the equivalent amount in grams:

350,000 mcg / 0.6 ml = 1,000,000 mcg / x ml

Cross-multiplying and solving for x, we get:

x = (0.6 ml * 1,000,000 mcg) / 350,000 mcg

x = 1.714 ml

Therefore, to administer 1 gram of the medication, you would need to give approximately 1.714 milliliters.

What is 30-60-90 traingle?

The 30-60-90 triangle is cut straight through the middle along its altitude, like one half of an equilateral triangle. Its name is derived from its three angles of 30 degrees, 60 degrees, and 90 degrees. Any triangle with angles of 30-60-90 will look like this: The hypotenuse is always twice as long as the shortest leg, and the length of the long leg can be calculated by multiplying the short leg by the square root of three. The shortest leg is across from the 30-degree angle.

By 30-60-90 triangle rule,

Side across 60° angle = x

Hypotenuse side = 2x= 15

Side across 30° angle = x√3

By solving,

2x= 15

x= 7.5cm

So side across 60° angle= 7.5 cm

Side across 30° angle = 7.5×√3

                                     = 7.5× 1.732= 12.99≈ 13cm

The statement "a line segment is a part of a line that is bounded by two distinct end points and contains every point on the line between its endpoints." is True because a line segment is defined as a part of a line that is bounded by two distinct end points and contains all the points on the line between those endpoints.

A line segment is a part of a line that has two endpoints and connects them. It is the shortest distance between two points and has a definite length, but no width or height. A line segment can be part of a straight line or a curved line.

A line segment is a section of a line that is defined by two distinct end points and includes every point on the line between them. It is the basic building block of geometry and can be used to measure distances, angles, and shapes.

The terminal side of a -630° angle in standard position is the negative y-axis. The correct option is d.

The terminal side of an angle in standard position is the ray that starts at the origin and rotates counterclockwise to reach the angle. A -630° angle means that we rotate clockwise from the positive x-axis (which is the initial side of all angles in standard position) by 630 degrees.

To find the terminal side of this angle, we can start by drawing a diagram. We start on the positive x-axis and rotate clockwise by 360 degrees to reach the negative x-axis. This leaves us with a remaining rotation of 630 - 360 = 270 degrees.

A rotation of 270 degrees takes us from the negative x-axis to the negative y-axis. Therefore, the answer is (d) negative y-axis.

In summary, the terminal side of a -630° angle in standard position is the ray that starts at the origin, goes left along the negative x-axis, and then goes down along the negative y-axis. The correct option is d.
