Answer:  The description is mentioned in the below explanation.

Step-by-step explanation:

Since  greatest integer function rounds down a real number to the nearest integer. for example, if f(x)=[x] and for x =1.3 f(x)= [1.3]= 1

or x= 0.9 f(0.9)= [0.9]= 0

Here, The given function, y=4[x+2]

Which is a greatest integer function and it is described on  [0,3)

So, For the values of  [tex]1 >x\geq 0[/tex],we take  x=0 ⇒ y= 4(0+2)= 8

For,  [tex]2>x\geq 1[/tex] , we take x=1, ⇒ y = 4(1+2)= 12

For,  [tex]3>x\geq 2[/tex] we take x=2, ⇒ y = 4(2+2)=16

The graph description for the open or close interval, is mean describe values of variable for the interval. The graph [tex]y=4[x+2][/tex] is described and the values of y we get are 8,12, and 16 for the values of x as 0,1 and 2.

Integer keeps the values as positive or the negative and graphed at the number line.

Given information-

The function of the graph given in the problem is,

[tex]y=4[x+2][/tex]

This function need to be describe on the points [0,3).

The close bracket is used in left side means the value 0 is included and the  open bracket is used in right side means the value 3 is excluded.

Thus find the value of variable y for the different intervals o x,

The interval is,

[tex]0\leq x<3[/tex]

         [tex]y=4(0+2)\\y=4\times2\\y=8[/tex]

         [tex]y=4(1+2)\\y=4\times3\\y=12[/tex]

         [tex]y=4(2+2)\\y=4\times4\\y=16[/tex]

The graph of the given point is attached below.

Thus the graph [tex]y=4[x+2][/tex] is described and the values of y we get are 8,12, and 16 for the values of x as 0,1 and 2.

The sperm whale's underwater duration is seven times that of the sea cow, showcasing remarkable breath-holding abilities, likely adapted for deep-sea foraging and hunting.

The relationship between the underwater durations of a sperm whale and a sea cow suggests that the sperm whale's capability is sevenfold that of the sea cow. Let's denote the sea cow's duration as "x." Accordingly, the sperm whale's underwater duration would be 7 times x.

In practical terms, if we assume the sea cow can stay submerged for 10 minutes (x = 10), then the sperm whale, being seven times more proficient, can stay underwater for 7 times 10, which is 70 minutes (7x = 7 * 10 = 70). This sevenfold difference implies a significant contrast in their breath-holding abilities.

The numerical representation extends universally; if the sea cow can endure underwater for "x" units of time, the sperm whale can endure for 7 times "x" units of time. This relationship showcases the remarkable adaptation of the sperm whale to extended submersion, likely linked to its deep-sea foraging behavior and hunting strategies.

In essence, the sperm whale can stay underwater for a duration that is seven times longer than that of the sea cow, highlighting its remarkable breath-holding capacity.

A sperm whale can stay underwater for 7 times longer than a sea cow, so it can stay underwater for 7 times the duration of a sea cow.

If a sperm whale can stay underwater 7 times longer than a sea cow, we can express this relationship as:

Time a sperm whale can stay underwater = 7 * Time a sea cow can stay underwater

So, if we let the time a sea cow can stay underwater be represented by 'x', then the time a sperm whale can stay underwater is:

7 * x

Therefore, a sperm whale can stay underwater for 7 times longer than a sea cow, which means it can stay underwater for 7x.

1(17/24) simplified is 41/24.

We have,

To simplify the mixed number 1 17/24, we need to convert it to an improper fraction.

To do that, we multiply the whole number (1) by the denominator of the fraction (24), and then add the numerator (17):

1 x 24 + 17 = 24 + 17 = 41

So, the mixed number 1 17/24 is equivalent to the improper fraction 41/24.

Therefore,

1(17/24) simplified is 41/24.

Answer: The correct option is 4.

Explanation:

The formula of law of cosine is,

[tex]a^2=b^2+c^2-2bc\cos(A)[/tex]

Where a,b,c are sides of the triangle and A is the interior angle of vertex A.

Reason for correct option:

From the above formula we can easily conclude that to find an unknown angle measure we need the length of all sides of the triangle.

In figure 4 all sides are given, so the correct option is 4.

Reason for incorrect option:

In figure 1,2 and three all sides are not known, so we can apply the cosine rule to mind the unknown angle measure.

Therefore option 1,2 and 3 are incorrect.

Answer:

There are infinitely many solutions.

Step-by-step explanation:

While solving a system of equations, if we get a true statement like 1=1, then there will be "infinitely many solutions" and if we get a false statement like 1=2, then there will be "no solution".

Here the statement is 4=4, which is a true statement.

So, there are infinitely many solutions.

Answer:

The distance between them in 2.5 min will be 320 ft

Step-by-step explanation:

Let

x--------------> Bill distance after 2.5  min------- > speed  45 ft/min

y--------------> Greg distance after 2.5  min------> speed 75 ft/min

z-------------> distance between them in 2.5 min

we Know that

z=x+y+20

Remember that

To find the distance multiply the speed by the time

so

x=45*2.5=112.5 ft

y=75*2.5=187.5 ft

therefore

z=x+y+20-----------> 112.5+187.5+20=320 ft

Final answer:

Bill and Greg's total distance apart after 2.5 minutes is 320 feet, calculated by adding their initial distance of 20 feet to the distance they covered in 2.5 minutes at their combined speed of 120 feet per minute.

Explanation:

Bill and Greg are walking away from each other with speeds of 45 and 75 feet per minute, respectively.

Since they are moving in opposite directions, their relative speed is the sum of their individual speeds, which is 45 + 75 feet per minute, or 120 feet per minute.

To find the distance between them after 2.5 minutes, we multiply their relative speed by the time elapsed. Therefore, the distance is:

Distance = Speed × Time = 120 feet/minute × 2.5 minutes = 300 feet.

We must also include the initial distance between them, which was 20 feet, so the total distance after 2.5 minutes is:

Total distance = Initial distance + Distance covered in 2.5 minutes = 20 feet + 300 feet = 320 feet.

Final answer:

The slope of the skateboard ramp, calculated using the rise over run formula, is 0.3. This is found by dividing the rise of 1.2 meters by the run of 4 meters.

Explanation:

The slope of a ramp is calculated as the rise divided by the run. To find the slope of the skateboard ramp, which rises 1.2 meters above the ground and runs 4 meters horizontally at the base, you would use the formula:

Slope (m) = Rise / Run

Here, the rise is the height the ramp rises above the ground, which is 1.2 meters, and the run is the distance along the ground, which is 4 meters horizontally. By substituting the given rise and run into the formula, you obtain:

Slope (m) = 1.2 m / 4 m = 0.3

So, the slope of the skateboard ramp is 0.3.

Answer:

  $5308.79

Step-by-step explanation:

The future value can be computed from ...

  FV = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual interest rate, n is the number of times per year it is compounded, and t is the number of years.

You have P = $5000, r = 0.03, n = 12 (months per year), t = 2.

Filling in the given numbers, we have ...

  FV = $5000(1 +.03/12)^(12·2) ≈ $5000(1.0617570) ≈ $5308.79

The amount of the withdrawal will be $5308.79.

Final answer:

To find the withdrawal amount for Myron's CD, the compound interest formula is used with the respective values plugged in. After 2 years, with 3% interest compounded monthly on a principal of $5000, the withdrawal amount is approximately $5,304.91.

Explanation:

The question deals with the calculation of compound interest for a Certificate of Deposit (CD), specifically with different compounding periods.

To calculate the withdrawal amount for Myron's 2-year CD with a principal amount of $5000 at a 3% interest rate compounded monthly, the formula for compound interest is:

[tex]A = P (1 + r/n)^{nt[/tex]

Where:

By plugging in Myron's values, we get:

[tex]A = $5000 (1 + 0.03/12)^{12\times 2[/tex]

Calculating this we find that A, the withdrawal amount, is approximately $5,304.91.

Answer: d.) The area of the new circle is 16 times larger.

Step-by-step explanation:

Let the radius of the original circle be r.

Then the area of the original circle will be :-

[tex]\text{A}_1=\pi r^2[/tex]

When she multiplies her original radius by four and repaints the circle.

The new radius = [tex]R=4r[/tex]

Then the area of the new circle will be :-

[tex]\text{Area}=\pi R^2\\\\\Rightarrow\ \text{Area}=\pi (4r)^2\\\\\Rightarrow\ \text{Area}=\pi (16r^2)\\\\\Rightarrow\ \text{Area}=16\pi r^2\\\\\Rightarrow\ \text{Area}=16(\pi r^2)\\\\\Rightarrow\ \text{Area}=16A_1[/tex]

Hence, The area of the new circle is 16 times larger.
