You need 3a^3 to equal a^3, so you would need at subtract 2a^3.

Since the problem is addition, add - 2a^3:

3a^3 + -2a^3 = 3a^3 - 2a^3 = a^3

Then you have -5b^3 and you need it to equal b^^3, so you would need to add 6b^3:

-5b^3 + 6b^3 = b^3

First box would be -2

Second box would be 6

Answer:

0.382

0.4

option (a)

Step-by-step explanation:

Formula to calculate probability

a)

probability = number of times event occur  / total number of trials

Experimental probability of landing on white = 191/500 = 0.382

b)

probability = favourable outcome / total outcome

Theoretical probability of landing on white = 2/5 = 0.4

c)

As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.

The student must calculate frequencies, relative frequencies, and probabilities based on the results from spinning a dial. The frequencies are the counts of outcomes, relative frequencies are these counts divided by total spins, and probabilities are based on the assumption of a fair spinner.

The question is about filling in a table with the results from spinning a dial 500 times. This tasks involves calculating frequencies, relative frequencies, and probabilities which are fundamental concepts in probability and statistics. Since we do not have the actual results, I will explain the process of completing the table:

If an outcome occurred 100 times in 500 spins, the frequency is 100. To calculate the relative frequency, divide 100 by 500, which equals 0.2. Round this to the nearest thousandth to get 0.200.

Remember to round all your final calculated values appropriately as per the instructions given in the question.

ANSWER

d. The amplitude is 2

period:

[tex]\frac{2\pi}{3} [/tex]

EXPLANATION

The given function is

[tex]f(t) = - 2 \cos(3t) [/tex]

This function is of the form,

f(t) = a cos(bt)

The amplitude of this function is |a|

where a=-2

[tex] | - 2| = 2[/tex]

The period of this function is given by,

[tex]T= \frac{2\pi}{b} [/tex]

But b=3,

[tex]T= \frac{2\pi}{3} [/tex]

Option D is correct.

A. a number and three is at most two

The inequality states that a number and three is less than or equal to two.

“Less than or equal to” means the same thing as “at most”.

So, the inequality states that a number and three is at most two.

ANSWER

A number and three is at most two.

EXPLANATION

The given inequality is

[tex]x + 3 \leqslant 2[/tex]

The emphasis is on the inequality sign.

The inequality sign is "≤"

"≤" means less or equal to.

"≤" also means at most

Therefore,

[tex]x + 3 \leqslant 2[/tex]

means the sum of a number and 3 is at most 2.

The correct choice is A

Step-by-step explanation:

The general equation of an ellipse has the following form:

[tex]\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1[/tex]

Where the point (h, k) is the center of the ellipse

In this case we have the equation

[tex]\frac{(x-9)^2}{4} + \frac{(y+2)^2}{25} =1[/tex]

Note that its shape matches that of a ellipse with center (9, -2)

[tex]a=\sqrt{4} \\a=2\\\\\\b=\sqrt{25}\\b=5[/tex]

Answer:

86

Step-by-step explanation:

Angles in a triangle add up to 180 degrees

add 74 with 20 to get 94

subtract 94 from 180 to get the value of x

180-94=86

The value of x in the triangle whose two interior angle values are given as 74 degrees and 20 degrees is 86 degrees.

A triangle is a closed 2-dimensional polygon with three angles and three straight sides.

According to the Triangle Angle Sum Theorem, the sum of the three interior angles in a triangle is always 180°.

Hence,

angleA + angleB + angleC = 180°

Given the data in the question;

We substitute our given values into the expression above.

angleA + angleB + angleC = 180°

74° + 20° + x = 180°

94° + x = 180°

x = 180° - 94°

x = 86°

Hence, the value of x in the triangle whose two interior angle values are given as 74 degrees and 20 degrees is 86 degrees.

Answer: last option.

Step-by-step explanation:

We know that the line is vertical and it passes through the point (3, -3).

Then, since it is vertical, the equation of this line will have the following form:

[tex]x = a[/tex]

Where "a" is the value of the x-coordinate (Because vertical lines passes through all points with the same x-coordinate)

Then, you can observe in the given point that the x-coordinate is 3. Therefore, the equation of the line is:

[tex]x=3[/tex]

ANSWER

[tex]x = 3[/tex]

EXPLANATION

The equation of a vertical line that passes through

[tex](x_1,y_1)[/tex]

is given by

[tex]x = x_1[/tex]

That is x equals the x-value of the point.

Since the vertical line passes through (3,-3).

Therefore the equation of a vertical line that passes through the point (3, –3).

Answer:

125 miles

Step-by-step explanation:

Write formulas for the amount of $ that would be due each of the two companies and set these equal to one another prior to solving for the number of days:

A:  $35 + ($0.45/mile)x  

B:  $60 + ($0.25/mile)x

Then $35 + ($0.45/mile)x = $60 + ($0.25/mile)x, or

($0.20/mile)x = $25

                                                                       $25

dividing both sides by $0.20 yields  x = ------------------- = 125 miles

                                                                    $0.20/mile

The charges made by the two companies would become equal after the 125th mile.  After that, Company B would become cheaper.

Ms. Call would need to drive at least 125 miles for the rental from Company B to be more cost-effective.

To find out when Company B becomes a better deal, we need to set up an equality and solve it for the number of miles. We can create the equation as follows:

Company A cost = Company B cost.

So, $35 + $0.45x = $60 + $0.25x.

Here x represents the number of miles driven. If we simplify this equation, we have:

$0.20x = $25.

Thus, solving for x: x = 25/0.20 = 125

So, Ms. Call would need to drive at least 125 miles in order for Company B to be a better deal.

Supplementary angles, totaling 180 degrees, are demonstrated by ∠2 and ∠4, as well as ∠3 and ∠5, in the context of lines b and c, as depicted in the diagram.

Supplementary angles are pairs of angles whose measures add up to 180 degrees. In the context of lines b and c, the identified supplementary angle pairs are ∠2 and ∠4, as well as ∠3 and ∠5. These pairs satisfy the condition that the sum of their measures equals 180 degrees. Visually, this relationship is evident in the provided diagram, reinforcing the concept of supplementary angles. Specifically, the equation ∠2 + ∠4 = 180° and ∠3 + ∠5 = 180° illustrates the supplementary nature of these angle pairs. Understanding supplementary angles is crucial in geometry, as it provides a fundamental principle for evaluating the relationships between angles formed by intersecting lines. In the given scenario, the angles ∠2, ∠4, ∠3, and ∠5 exhibit supplementary properties, emphasizing their collective role in forming a straight line and contributing to the overall understanding of geometric configurations.

Step-by-step explanation:

If the graph of the function [tex]y=kf(x) +d[/tex]  represents the transformations made to the graph of [tex]y= f(x)[/tex]  then, by definition:

If  [tex]0 <k <1[/tex] then the graph is compressed vertically by a factor k.

If  [tex]|k| > 1[/tex] then the graph is stretched vertically by a factor k

If [tex]k <0[/tex]  then the graph is reflected on the x axis.

If [tex]d> 0[/tex] the graph moves vertically upwards d units.

If [tex]d <0[/tex] the graph moves vertically down  d units.

In this problem we have the function [tex]y = cos⁡x[/tex]

And we know that The graph of [tex]y = cos⁡x[/tex] is transformed with  a vertical compression by a factor of 1/2 and a translation 3 units up

therefore it is true that [tex]0 <k <1[/tex] and [tex]k=\frac{1}{2}[/tex] and  [tex]d =3> 0[/tex]
