The percent of the first change is greater by 2.36%.

Time in 1st week = 28.8 sec

Time in 2nd week = 27.6 sec

Time in 3rd week = 27.1 sec

∴ Change of time from week 1 to week 2 = (28.8 - 27.6) sec

                                                                    = 1.2 sec

∴ Percent of change from week 1 to week 2 = [tex]\frac{time change}{1st week time} \times 100[/tex] %

                                                                         = [tex]\frac{1.2}{28.8} \times 100[/tex] %

                                                                         = 4.17%

∴ Change of time from week 2 to week 3 = (27.6 - 27.1) sec

                                                                     = 0.5 sec

∴ Percent of change from week 2 to week 3 = [tex]\frac{Time change}{2nd week time} \times 100[/tex] %

                                                                          = [tex]\frac{0.5}{27.6} \times 100[/tex] %

                                                                          = 1.81%

∴ The greater change was in the first week. The amount by which it was greater is = (4.17 - 1.81) %

                = 2.36%

Answer) The percent of the first change is greater by 2.36%.

The table that shows the growth rate of Plant 1 which is 4 cm/week, and the graph that gives the growth rate of Plant 2 as 2 cm/week gives the correct option as C;

C. I think that plant 1 grows more per day and I disagree with Aaliyah's reasoning

A proportional relationship between two variables is one in which one variable is a multiple of the other.

The possible table in the question is presented as follows;

Plant 1

The values on the graph are;

Plant 2

The rate, r1, of growth of Plant 1 is therefore;

r1 = 8 cm/(2 weeks) = 4 cm/week

The rate, of growth, r2, of plant 2 is found as follows;

r2 = 4 cm/(2 weeks) = 2 cm/week

Given that Plant 1 grows faster at 4 cm/week, than Plant 2, that grows at 2 cm/week, the correct statement is since Plant 1 grows 4 cm/week and Plant 2 grows 2 cm/week, Plant 1 grows more per day.

The correct option is therefore;

Andrew has 7 dimes and 15 quarters, as obtained from the system of linear equations so formed.

A system of linear equations is a set of two or more linear equations. Linear equations refer to the equations that involve two or more variables in the form of "ax + b".

Given:

To find: Number of dimes and quarters.

Finding:

=> By unitary method, $4 = 4(100) = 400 cents

d + q = 22 (Number of coins) => d = 22 - q (eqn1)

and 10d + 25q = 400 (amount of coins)

=> 10 ( 22 - q ) + 25q = 400

=> 220 - 10q + 25q = 400

=>  15q = 400 - 220 = 180

=> q = 12, i.e., number of quarters = 22 upon the solving of this system of linear equations.

On substituting the value of q in eqn1, we get: d = 22 - 15 = 7, i.e., number of dimes = 7.

Hence, Andrew has 7 dimes and 15 quarters, as obtained from the system of linear equations so formed.

The domain of the function f(2x) is (-1, 1).

Given that a function f has domain (-2,2) and range (-3,5).

We need to determine the domain of the function f(2x).

To determine the domain of the function f(2x), we need to consider how the original domain (-2,2) is affected by the transformation of multiplying the input by 2.

When we multiply x by 2, it stretches or compresses the function horizontally.

In this case, multiplying by 2 will stretch the original domain by a factor of 1/2.

To find the new domain, we divide the original domain endpoints by 2:

New domain = (-2/2, 2/2) = (-1, 1)

Therefore, the domain of the function f(2x) is (-1, 1).

The difference of time taken by Rosa and Maya to ran the hurdles is 4.242 seconds .

The correct option is B .

Given, time taken by Rosa and Maya to ran the hurdles.

Time taken by Rosa to ran the hurdle = 58.32 seconds .

Time taken by Maya to ran the hurdle = 54.078 seconds .

Difference between the time taken:

Rosa is taking more time to cover the distance than Maya . Thus the speed of Rosa is less than the speed of Maya .

Relationship between speed, time and distance.

Distance = Speed × Time

Subtract time taken by Rosa to ran the hurdle from time taken by Maya to ran the hurdle.

Herein we find an hypothetical triangles with all side lengths known.  A criterion is using the law of cosine, a possible triangle has cosine values between - 1 and 1. Then, we proceed to check for each side:

cos A = - (a² - b² - c²) / (2 · b · c)

cos A = - (25² - 2² - 24²) / (2 · 2 · 24)

cos A = - 0.469

cos B = - (b² - a² - c²) / (2 · a · c)

cos B = - (2² - 25² - 24²) / (2 · 25 · 24)

The slope of a line indicates its steepness. The slope is determined mathematically as "increase over run" (change in y divided by change in x).

The conventional form of a line equation is ax + by + c = 0. Here, the coefficients are a and b, the variables are x and y, and the constant term is c. It is a one-degree equation with variables x and y. The coordinates of both the point on the line that appears in the coordinate plane are represented by the values of x and y.
