Final answer:

The function y=230(0.98)ˣ is an exponential decay model depicting how a quantity decreases over time. The graph starts at 230 (the initial value) and decreases at a decay rate of 0.98 each step. To express small or large numbers succinctly, standard exponential form is used.

Explanation:

The exponential equation given, y=230(0.98)ˣ, represents a mathematical function known as an exponential decay model. To draw the appropriate graph for this function, you would plot the y-value against x on a Cartesian plane. The x-axis would indicate the time or trial number, and the y-axis would represent the value of y at that time. The decay rate in this equation is 0.98, which means that with each step in x (assuming x is a time interval), the quantity y decreases to 98% of its previous amount. The initial value, or mean, of the equation is 230, which is the starting point of the graph at x=0.

The mentioned exponential curve would start at y=230 and decrease gradually as x increases. If you were to shade the area for the probability that a student has less than $0.40 in his or her pocket, you would first need to solve for x when y=0.40, and then shade under the curve to the left of the corresponding x-value on your graph. This would visually represent P(x < 0.40).

To express numbers in standard exponential form, you use a coefficient between 1 and 10 multiplied by a power of 10. For example, converting 9.3 times 10 to the power of 7 is an example of expressing a very large number in exponential form. For small values of x, the exponential curve will show slower change, which increases rapidly for larger values of x.

If the tables are arranged in a square formation, there would be 8 tables in each row and each column because the square root of 64 is 8.

The question is asking about arranging the 64 tables in a square formation. If we arrange the tables in a square, there will be an equal number of tables in each row and column. That means you need to find the square root of 64 because the square root is the number that, when multiplied by itself, equals the original number. The square root of 64 is 8, so there would be 8 tables in each row and each column of the square formation.

Answer:

Given the statement: The length of an aquarium, which has the form of a rectangular solid, is equal to 5 decimeters, and the width is 4/5 the length.

Since, aquarium is in the form of a rectangular solid.

Length of an aquarium(l) = 5 dm

Width of an aquarium(w)= [tex]\frac{4}{5}\times 5 = 4 dm[/tex]

It is also given that when you put 40 liters of water into the aquarium, it was full to [tex]\frac{2}{3}[/tex] its volume.

Volume of Rectangular solid(V) is given by;

[tex]V = l \times b \times h[/tex] where l is the length , w is the width and h is the height of the rectangle respectively.

Volume(V) of an aquarium = [tex]\frac{3}{2} \times 40 = 60[/tex] liter.

Using volume formula to calculate the height(h);

[tex]60 = 5 \times 4 \times h[/tex]

[tex]60 = 20h[/tex]

Divide both sides by 20 we get;

h =  3 dm                      [ 1 liter = 1 cubic dm]

We have to find the what part of length makes up the height of the aquarium.

[tex]h = \frac{3}{5} l[/tex]       where l = 5 dm

therefore, [tex]\frac{3}{5}[/tex] part of the length makes up the height of the aquarium.

The image of the triangle after a dilation with a scale factor of 5/6 is similar to the original triangle. The Option C

No, a dilation with a scale factor of 5/6 does not change the similarity of a triangle. Dilations involve scaling the size of the original figure, but the shape and angles remain unchanged.

In this case, the sides of the triangle will be uniformly reduced by a factor of 5/6, maintaining the proportional relationships between the sides. As a result, the dilated triangle will still be similar to the original triangle and the angles will retain their measurements, just as in the initial triangle.

Answer:

A) [tex]x=\frac{h-6}{1.5}[/tex]

B)[tex]26[/tex]

Step-by-step explanation:

A)Let's call the height of the plant [tex]h[/tex] and this height will be 6 inches on the day 0 like this:

[tex]h=6[/tex]

on the day 1 of the month the plant will have the original 6 inches plus the height it grew the first day  which will be 1.5 inches

[tex]h=6+1.5[/tex]

on the day 2 of the month the plant will have the original 6 inches plus the height it grew the first day plus the height it grew the second day which will be again 1.5 inches

[tex]h=6+1.5+1.5[/tex]

we can see that on the day 1 we add 1.5 inches one time, on the day 2 we add 1.5 inches two times. it is possible to say now that the height will be the original 6 inches plus 1.5 times the days of the month like this:

[tex]h=6+1.5x[/tex]

We will solve for x because we need to find the number of days for a given h like this:

[tex]h=6+1.5x\\h-6=1.5x\\x=\frac{h-6}{1.5}[/tex]

and this will be our equation that trent can use to find the number of days (x), it will take the sunflower to a given height.

B)to know how many days it will take for he sonflower to grow to a height of 45 inches we replace h in the equation with 45 like this:

[tex]x=\frac{h-6}{1.5}\\x=\frac{45-6}{1.5}\\x=26[/tex]

The sunflower will take 26 days to grow to a height of 45 inches

Answer:

3598 (or 3600 to 2.s.f)

Step-by-step explanation:

You need to recall that the circumference is π * d

So if we have the circumference, we can divide by π to get d:

11,304 ÷ π = 3598 or 3600  to 2.s.f

Answer:

[tex]D\approx 3600[/tex]

Step-by-step explanation:

Circumference is given by this formula below. What gives us the radius.

[tex]C=2\pi R \Rightarrow 11304=6.28R \Rightarrow R=1800[/tex]

The diameter of the circle is calculated by dividing the Circumference, 11304 in this case by [tex]\pi[/tex]

[tex]C=2\pi R \Rightarrow C=\pi D \Rightarrow D=\frac{C}{\pi} \Rightarrow D=\frac{11304}{\pi} \Rightarrow D\approx 3600[/tex]

The expression -4(3x-5) is equivalent to -12x + 20 by applying the distributive property of multiplication over subtraction.

Answer:

x = 5 and y = -2

Step-by-step explanation:

Here you have given what y is equal to, this means you can sub this into the first equation:

3x - 2(x - 7) = 19

Expand the brackets:

-2 * x = -2x

-2 * -7 = 14

3x -2x +14 = 19

Move the +14 over to the other side making it a -14:

3x - 2x = 19 - 14

3x - 2x = 5

3x - 2x = x

So x = 5

Now sub this into the first equation:

3(5) - 2y = 19

15 - 2y = 19

Move the -2y over to the other side making it a +2y, and move the +19 over to the other side making it a -19:

15 - 19 = 2y

-4 = 2y

Divide both sides by two:

y = -2

So x = 5 and y = -2

a)

very straighforwards, a rectangle of 24 in x18 in has an area of simply that product.

however, that gives us in², so we firstly need to convert those inches to cm, so since 1 inch is 2.54 cm, then 24 inches is just 24*2.54, and likewise 18 inches is just 18*2.54.

so the tabletop is (24*2.54) * (18*2.54) = 2787.09 cm².

b)

each bag can cover 260 cm², she can't buy any partials, half a bag or a quarter of a bag, is a whole bag or nothing.

well, if she only buys one, she'll be able to cover 260 cm², however the tabletop is 2787.09 cm², so, how many times does 260 go into 2787.09?  2787.09 ÷ 260 ≈ 10.72.

so she needs 10 bags plus 0.72 of another, the store doesn't sell partials, so she'll need to buy another bag, namely 11 bags.

c)

well, each bag is 3.76, for eleven bags that'll be 11*3.76 = 41.36.

Answer:

It is a rational number and real number

Explanation:

it is a real number because it can become .75 and that is a real number.

it is a rational number because assume that 3/4 is a rational number. Since every rational number can be expressed as a/b form which do not have any common factor so we can say that a/b = 3/4 Squaring both side we get: a2/b2 = 9/16 a2 = (9/16) b2 Or we can say b2 = a2(16/9) a2 is divided by 9. So we can say that a is divided by 9. It implies that there exist some number c such that a/9 = c a = 9c By squaring both side we get a2 = 81 c2 Put the value of a2 from the equation a2 = (9/16) b2 we get: (9/16)b2 = 81c2 this tends to b2/ 9 = 16 c2 It implies that b2 is divided by 9. So we can say that b is divided by 9. This implies that a and b have a common factor 9. Since a and b have common factor therefore 3/4 is not a irrational number. Hence 3/4 is a rational number.

Answer:

3/4 is a rational number and also a real number

Step-by-step explanation:

to prove 3/4 is real

3/4 is a fraction. It is a proper fraction since denominator  is grater than numerator.

3/4 can be written as 0.75 which is terminating decimal.

Therefore 3/4 is a real number

To prove 3/4 is a rational number

3/4 is the form of p/q.

Therefore 3/4 is a rational number.

Answer:

(C) This function is an exponential.

Step-by-step explanation:

Exponentials are the fastest growing functions. In this case, the values in table (C) exhibit an exponential growth in that for every increase in x there is a tripling of the previous value. This would correspond to x being a power of the base 3.

Generally, the y-values will be greatest for very large values of x in increasing continuous functions such as y = x^2. To identify exactly which function among your tables has this property would require reviewing the actual tables.

It's quite difficult to give you an accurate answer without having access to the actual tables of values. However, we can go by a general principle that in mathematics, specifically in the study of continuous functions, the y-values can be greatest for large values of x in case of increasing functions. These are functions where the value of y (or the output) increases as the value of x (or the input) increases. For instance, the function y = x^2 is an increasing function for x greater than 0. As x approaches infinity, so does the value of y. Therefore, the function that represents this behaviour will yield the greatest y-values for very large values of x. However, without knowing the precise functions represented by your tables it is impossible to give a definite answer.
