Describe the graph y=4[x+2] on [0, 3). Be specific in your description.
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.
How to graph integer on a number line?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,

Eliza paints a circle on her bedroom wall as part of a mural. After she paints it, she decides that she wants a much bigger circle. So, she multiplies her original radius by four and repaints the circle. Which statement best describes Eliza's solution?
a.) The area of the new circle is two times larger.
b.) The area of the new circle is four times larger.
c.) The area of the new circle is eight times larger.
d.) The area of the new circle is 16 times larger.
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.
What is the slope of this skateboard ramp if it rises 1.2 meters above the ground and runs 4 meters horizontally at the base?
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.

Bill and Greg are walking in opposite directions with speeds of 45 and 75 feet per minute. When they started, the distance between them was 20 feet. What will be the distance between them in 2.5 min?
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.
The difference of the squares of two positive consecutive even integers is 76. find the integers. use the fact that, if x represents an even integer, then x+2 represents the next consecutive even integer.
The two positive consecutive even integers that, when their squares are subtracted, equal 76 are 18 and 20.
Explanation:In this problem, the two positive consecutive even integers can be represented as x and x+2. The problem states that the difference of their squares is 76, which can be put into the equation (x + 2)^2 - x^2 = 76. By simplifying this equation, we get 4x + 4 = 76. Solving for x, we find that x = 18. Therefore, the two consecutive even integers are 18 and 20.

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.

Myron put $5000 in a 2-year CD paying 3% interest, compounded monthly. After 2 years, he withdrew all his money. What was the amount of the withdrawal?
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:
A = the amount of money accumulated after n years, including interest.P = the principal amount (initial deposit).r = the annual interest rate (decimal).n = the number of times that interest is compounded per year.t = the time the money is invested for in years.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.
