Question #2 [tex]5x+9\leq 4[/tex]

Answer:

B

Step-by-step explanation:

The red line is y = 2x + 3 and the blue line is y = -2x - 4. The solution will be shaded on the left side of the red line and below the blue line which is Graph B.

Answer:

B

Step-by-step explanation:

Check the inequalities

Answer:

C would be irrational.

Step-by-step explanation:

Irrational means that you cannot make a distinct ratio with the number. One of the more famous irrational numbers are π. You cannot make π into a fraction with whole numbers for a numerator and denominator.

Other examples of irrational numbers are square roots that are not perfect square roots. C is not a perfect square so it is irrational.

Answer:

9.5 feet

Step-by-step explanation:

So let's review the equations we need to know.

Circumference= π x d or π x 2r

Since we are solving for r, let's stick with the 2nd one.

Next, plug in the values.

59.66=3.14 x 2r

simplify.

59.66=6.28r

9.5=r

done!

the radius is 9.5 feet!

Answer:

384 3/4

341 1/4

box A

Step-by-step explanation:

The volume of the box is given by the formula:

Volume = length * width * height

The volume of the box A is:

Volume_A = 9.5 * 3 * 13.5 = 384.75 cm3 = 384 3/4 cm3

The volume of the box B is:

Volume_B = 10 * 3.25 * 10.5 = 341.25 cm3 = 341 1/4 cm3

The volume of the box A is greater than the volume of the box B, so Megan should use the box A

Answer:

a) see the attached file

b) Coordinates of vertex = (0, 4)

Step-by-step explanation:

Given:

Focus of parabola is [tex](0,7)[/tex] and the directrix is [tex]y=1[/tex]

To sketch: the parabola

To find: coordinates of the vertex

Solution:

As the focus lies on the y-axis and y-coordinate of the focus is positive,

equation of parabola is [tex](x-h)^2=4p(y-k)[/tex]

Here, [tex](h,k)[/tex] denotes the vertex of parabola, focus is [tex](h,k+p)[/tex] and the directrix is [tex]y=k-p[/tex]

According to question,

[tex](h,k+p)=(0,7)[/tex]

[tex]k-p=1[/tex]

So, [tex]h=0[/tex]

[tex]k+p=7\,,\,k-p=1[/tex]

On adding these equations,

[tex]k+p+k-p=7+1\\2k=8\\k=4[/tex]

Put [tex]k=4[/tex] in [tex]k+p=7[/tex]

[tex]4+p=7\\p=7-4\\p=3[/tex]

So, equation of parabola is [tex](x-0)^2=4(3)(y-4)\Rightarrow x^2=12(y-4)[/tex]

For part a), see the attached file.

b)

Coordinates of vertex = [tex](h,k)=(0,4)[/tex]

Answer:

[tex]9*10^{12}km[/tex]

Step-by-step explanation:

[tex]9,460,730,472,580.8 km[/tex]

First, we can work out 5% of our number, by multiplying it by 0.05

[tex]9,460,730,472,580.8 * 0.05 = 473,036,523,629[/tex]

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.

[tex]9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}[/tex]

We can see that [tex]9*10^{12}[/tex] is in the range of valid answers, as:

[tex]8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}[/tex]

So, our final answer is:

[tex]9*10^{12}km[/tex]

Answer:

See the explanation.

Step-by-step explanation:

The Pythagorean theorem states that a^2 + b^2 = c^2, where a and b are the legs of the triangle and c is the hypotenuse (diagonal, longest side) of the triangle.

We can see that the legs are labeled 15 (blue) and 8 (red). Substitute that into the equation.

(8)^2 + (15) ^2 = c^2

From there, we can simplify and solve for c.

64 + 225 = c^2. Add.

289 = c^2. Take the square root.

c = 17.

I hope this helps!

Answer: 17

Pro tip: 3/4/5, 5/12/13 and 8/15/17 are the first three Pythagorean Triples on the list and teachers like to use them for problems.  The multiples also come up, like 6/8/10.  Learn these and save yourself some calculation down the road.

Let's do it like they want

a² + b² = c²

8² + 15² = c²

64 + 225  = c²

289 = c²

√289 = √c²

17 = c

First, let's square all the given measures, so we have 25, 27, 4, and 49. For three measures to form the sides of a right triangle, two of these squares have to add up to the third.

By inspection, we see that the measures of [tex]\boxed{5,\sqrt{27},7}[/tex] form a right triangle, since [tex]25+27=49.[/tex]

Answer:

x = 25

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

2x+ x+15 +90 = 180

Combine like terms

3x+ 105 = 180

Subtract 105 from each side

3x+105-105 = 180-105

3x = 75

Divide each side by 3

3x/3 = 75/3

x = 25

The value of X is 25 degree.

The two types of angle measurements are:

1) Degrees ( ° )

2) Radians ( r)

Answer:

C

Step-by-step explanation:

The angle adjacent to x on XY = 115° ( corresponding angle )

This angle and x are adjacent and supplementary , thus

x = 180 - 115 = 65 → C

Answer:

65⁰

Step-by-step explanation:

x + 115⁰ = 180⁰ (co exterior)

x = 180 - 115 = 65⁰

Answer:

The number of heads observed is 121.14 heads

Step-by-step explanation:

The formula for the z-score of a proportion is given as follows;

[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{pq}{n}}}[/tex]

Where:

[tex]{\hat{p}[/tex] = Sample proportion

p = Population success proportion = 0.5

q = 1 - p = 1 - 0.5 = 0.5

n = Number in of observation = 200

z = 2.99

Hence, we have;

[tex]z=\dfrac{\hat{p}-0.5}{\sqrt{\dfrac{0.5 \times 0.5}{200}}} = 2.99[/tex]

Therefore;

[tex]{\hat{p}-0.5}{} = 2.99 \times \sqrt{\dfrac{0.5 \times 0.5}{200}} = 2.99 \times\dfrac{\sqrt{2} }{40}[/tex]

[tex]{\hat{p}[/tex] = 0.6057

[tex]Whereby \ \hat p = \dfrac{Number \ of \ heads}{Number \ of \ observation} = \dfrac{Number \ of \ heads}{200} = 0.6057[/tex]

∴ The number of heads observed = 200 × 0.6057 = 121.14 heads.

What does the graph look like

Step-by-step explanation:

The inequality given is y> fx+5, if we plot the graph of the two inequalities, the graph of the inequalities will never meet at any point.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal symbol ()" to indicate that two values aren't equal. But several inequalities are utilised to compare the numbers, whether they're less than or higher than.

The different inequality representations, properties, and methods for resolving linear inequalities throughout one variable or two variables will all be covered in this article along with examples. The inequality given is y> fx+5, if we plot the graph of the two inequalities, the graph of the inequalities will never meet at any point.

Therefore, the inequalities have no solution since their graph does not intersect or overlap.

First of all, what graph and second, what is "shown below"

The graph will be a line that passes through these points. In this case, the line will have a positive slope of 3 and a y-intercept of 1. None of the options is correct.

The graph of the equation y = 3x + 1 is a straight line.

To graph this equation, we need to plot points that satisfy the equation and then connect those points to create the line.

We can choose any values for x and calculate the corresponding y values using the equation. Let's choose a few x-values to get started:

When x = 0:

y = 3(0) + 1 = 1

So we have the point (0, 1).

When x = 1:

y = 3(1) + 1 = 4

So we have the point (1, 4).

When x = -1:

y = 3(-1) + 1 = -2

So we have the point (-1, -2).

We can continue this process and plot more points to have a clear representation of the line.

Once we have a few points, we can connect them with a straight line.

The resulting graph will be a line that passes through these points. In this case, the line will have a positive slope of 3 and a y-intercept of 1. Since Kesley draws the wrong x-intercept.

None of the given options is correct.
