Answer:
In a coordinate axis, the horizontal line is called the x-axis, and the vertical line is called the y-axis.
1) Then if you have a point (x, y), to graph this you go at the horizontal axis to find the value x,
2) Starting from the point you already found, now you need to move y units in the vertical axis.
Now we want to graph the point (0, 3.5).
First we need to locate the value 0 in the horizontal axis, this is the point where both axes intersect.
Now we move 3.5 units, because the number is positive, we move 3.5 units upwards.
The graph of the point is shown below.

Answer:
Side length = 5 root 2
perimeter is (5 root 2)*3
Step-by-step explanation:
Use pythagoras
a^2 = b^2 + c^2
a^2 = 5 root 2
(5 root 2)^2 = (c^2)/2 + c^2
75 = (c^2)/2 + c^2
150 = c^2 + 2c^2
150 = 3c^2
50=c^2
root of 50 = 5 root 2
as it is equiliateral triangle all sides are the same
Answer:
Side: 10
Perimeter: 30
Step-by-step explanation:
An equilateral triangle has a height of 5√3. What is the length of each side in the equilateral triangle? What is the perimeter of the equilateral triangle?
In triangles with angles with 30°, 60°, and 90°, the hypotenuse (the angle opposite to the 90° angle) is twice as long as the base, and the height is √3 times as long as the base. To make it easier, this is a list of the sides:
x = base
√3 * x = height
2x = hypotenuse.
Look at the drawing I have attached below
If AD is the base of the triangle ADC, then CD, the height is √3 times AD. If we set AD as x, CD = √3*x = 5√3
√3*x = 5√3
Divide both sides by √3.
x = 5
Then, because altitudes in equilateral triangles bisect the base (CD cuts AB in half), then AB = 10.
The sides in equilateral triangles are equal, so each side is 10.
Then, the perimeter must be 30.
I hope this helps! Feel free to ask any questions!

What is the smallest 3-digit number of the form aaa such that it is divisible by 9? (Here, a represents a digit.)
Answer:
If all three digits need to be the same (I assume that's what aaa means) it's 333
Step-by-step explanation:
For a number XYZ to be divisible by 9, X+Y+Z must be divisible by 9. Here's why:
X*100 + Y * 10 + Z = X + Y + Z + 99*X + 9*Y = X + Y + Z + 9(11X + Y)
So we need to find the smallest a so that a+a+a = 3a is divisible by 9. The smallest would be 0, but 000 is not a real 3-digit number. The next one is 3.
A sinusoidal function whose frequency is 3, maximum value is 15, minimum value is -3 has a y-intercept of 6.
Which function could be the function described?
a. f(x)=9sin(x/3)+6
b. f(x)=9sin(6pix)+3
c. f(x)=9sin(3x)+3
d. f(x)=9sin(6pix)+6
please explain if you can, if not that’s ok!
Answer:
A. f(x) = 9sin(x/3) + 6
Step-by-step explanation:
First, we can eliminate B and C because they have the wrong vertical shift.
Since the y intercept is 6, this means the function has a vertical shift up 6 units, represented by a +6 at the end of the equation.
The amplitude is 9, found by calculating the difference between the minimum and maximum values, and dividing it by 2.
(15 - (-3)) / 2
18 / 2
= 9
Using a calculator, find the period given the frequency.
The period (coefficient of x) is 1/3.
So, putting all of these constants together, the correct equation is:
A. f(x) = 9sin(x/3) + 6
Answer:
A. f(x) = 9sin(x/3) + 6

A football team tries to move the ball forward as many yards as possible on each play, but sometimes they end up behind where they started. The distances, in yards, that a team moves on its first five plays are 2, 21, 4, 3, and 25. A positive number indicates moving the ball forward, and a negative number indicates moving the ball backward?
Required Question:
Which number in the list is the greatest?
Answer:
25 yards
Step-by-step explanation:
Given
[tex]Distance:2\ 21\ 4\ 3\ 25[/tex]
Required
The greatest distance moved
To do this, we make comparison between the 5 distances given and select the greatest.
By comparison:
[tex]25 > 2[/tex]
[tex]25 > 21[/tex]
[tex]25 > 4[/tex]
[tex]25 > 3[/tex]
Hence, the greatest distance is 25 yards

Drag each inequality to the correct location on the table based on whether its
graph will have a dashed or a solid boundary line.
Answer:
y>2x+8: Dashed x+1/2y is less than or equal to 12: Solid y is greater than or equal to 2/3x-6: Solid -4x+2y<10: Dashed
Step-by-step explanation:
If there is a < or > sign, it is dashed, because the answer you get is not part of the solution (it is either less than or greater than the solution). If it is a less than or greater than or equal to sign (with the line under it) the line will be solid because the answer you get is part of the solution.
The boundary line will not be included in the solution set. Therefore, the boundary line will be dashed. The table shows the following:
Dashed if the boundary line is not included in the solution set.
Solid if the boundary line is included in the solution set.
The inequalities that will have a dashed boundary line are:
y > 2x + 5
x + y ≤ 12
The inequalities that will have a solid boundary line are:
y ≤ 2x - 6
-4x + 2y - 10 ≤ 0
Here is an explanation of why each inequality will have the boundary line that it does:
y > 2x + 5
This inequality is not equal to 2x + 5, so the boundary line will not be included in the solution set. Therefore, the boundary line will be dashed.
x + y ≤ 12
This inequality is equal to x + y ≤ 12, so the boundary line will be included in the solution set. Therefore, the boundary line will be solid.
y ≤ 2x - 6
This inequality is equal to y ≤ 2x - 6, so the boundary line will be included in the solution set. Therefore, the boundary line will be solid.
-4x + 2y - 10 ≤ 0
This inequality is not equal to -4x + 2y - 10, so the boundary line will not be included in the solution set. Therefore, the boundary line will be dashed.

If the simple interest on $1,000 for 5 years is $300, then what is the interest rate?
Answer:
6%/year
Step-by-step explanation:
Solving our equation
r = 300 / ( 1000 × 5 ) = 0.06
r = 0.06
converting r decimal to a percentage
R = 0.06 * 100 = 6%/year
The interest rate required to
accumulate simple interest of $ 300.00
from a principal of $ 1,000.00
over 5 years is 6% per year.
