Step-by-step explanation:
Given
k = - 2
Now evaluating
√- 72 * - 2
= √ 144
= √ ( 12)²
= 12
Hope it will help you :)❤
The evaluated solution of √-72k for k = -2 is 12.
What is an expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given expression as :
⇒ √-72k
And k= -2
To Evaluate the expression
Now Substitute the value of k= -2 in the expression
⇒ √- 72 × - 2
⇒ √ 144 [√ 144 = 12]
⇒ 12
Hence, the evaluated solution of √-72k for k = -2 is 12.

Answer:
The slope is 2
Step-by-step explanation:
Pick two points and plug into this equation: y2-y1/x2-x1
(-3,2) and (-1,6)
2-6/-3-(-1)=-4/-2= 2
Answer:
The slope of the linear function is 2
Step-by-step explanation:
Calculating the Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The table shows four points: (-3,2), (-1,6), (1,10), and (3,14). To find the slope on the line passing through them we only need two, for example (-3,2), (-1,6):
[tex]\displaystyle m=\frac{6-2}{-1+3}[/tex]
[tex]\displaystyle m=\frac{4}{2}=2[/tex]
Any other pair of points should give the very same value for the slope. Use (1,10), and (3,14):
[tex]\displaystyle m=\frac{14-10}{3-1}[/tex]
[tex]\displaystyle m=\frac{4}{2}=2[/tex]
Thus, the slope of the linear function is 2

Can someone help me calculate angles? P2
Answer:85
Step-by-step explanation: In this problem you are trying to find the missing angle of a line. In a line all angles have to add up to 180 so what you wanna do first is add 55 and 40 which gives you 95. Next, you wanna subtract 95 from 180 which will give you 85. Now you know the missing angle.

This is the answer upon dividing the polynomial.
Let the vector \mathbf{v}v have an initial point at (1, -2)(1,−2) and a terminal point at (0, 0)(0,0). Plot the vector \mathbf{v}v and afterwards follow the guided steps to analyze the vector.
Given that the initial point of the vector is (1,-2) and the termination point of the vector is (0,0).
So, the tail of the vector is at point (1,-2) and the head of the vector is at (0,0). The vector, [tex]\vec{v}[/tex], has been shown in the figure.
The magnitude of the vector:
[tex]|\vec{v}|=\sqrt{(1-0)^2+(-2-0)^2}=\sqrt{1+4}=\sqrt{5}[/tex]
The direction of a vector is the angle made by a vector with the positive direction of the x-axis.
From the figure, [tex]\theta = 180 \degree\tan ^{-1} \left|\frac {0-(-2)}{0-1}\right|[/tex]
[tex]\theta = 180 ^{\circ} - \tan^{-1}(2) = 180 ^{\circ} - 63.43^{\circ}[/tex]
[tex]\theta =116.57 ^{\circ}[/tex]
Hence, the required vector having a magnitude [tex]\sqrt {5}[/tex] and direction [tex]116.57 ^{\circ}[/tex] has been shown in the figure.

Remember Rise/Run
also remember this formula:
y2-y1/
x2-x1
Your coordinates are: (-2, 1) (-3, -3)
-3-1/
-3-(-2) = -4/-1 or 4
Two negatives cancel out and make it a positive.

Explain why the function of f(x)=4x^2+8x is neither even or odd
Answer:
By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
Step-by-step explanation:
We need to explain why the function of [tex]f(x)=4x^2+8x[/tex] is neither even or odd
First we will understand, when the function is even and odd
Even function:
A function is even if f(-x) = f(x)
Odd function:
A function is odd if f(-x) = -f(x)
So, if we get the above result by putting x = -x, then we can say that the function is even or odd.
If we don't get any of the above results then the function is neither even nor odd.
So, for the given function: [tex]f(x)=4x^2+8x[/tex]
Put x = -x
[tex]f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x[/tex]
So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
given a-2b=8, 4a+3b= 21; prove b= -1
please give a step by step answer
Answer:
Step-by-step explanation:
We can solve this with some pretty simple substitution
First write that a=2b+8
and our reasoning for this is that we added 2b from the first equation
Then write
4(2b+8)+3b=21
After we figured out what A was in the previous part we are able to substitute that into our other equation
Then you solve for b from here
8b+32+3b=21
11b=-11
b= -1

The way I learned it was that if they dont have the same variables dont touch them, so what I did was multiply the like numbers (2 and 5). Why are they alike? Because they don't have a variable! I then just put the X sign there to show that there is no other way to multiply this. If it where addition, it would be 10+a so that would equal 10a.
Katherine is deciding which catering company she should use for Mom’s 50th birthday party. At Bashful’s Birthday Blast there is a fee of $16.95 and a charge of $9.00 per person.

Find the value of X in the measure of angle 2.
Answer:
x = 11, ∠ 2 = 146°
Step-by-step explanation:
∠ 2 and 146° are corresponding angles and are congruent, then
∠ 2 = 146°
Thus
13x + 3 = 146 ( subtract 3 from both sides )
13x = 143 ( divide both sides by 13 )
x = 11

What is the slope of the line passing through the points (0, 4) and (-8, -1)?
Enter your answer in the box.
Answer:
0.625
Step-by-step explanation:
Given the points :
(0, 4) and (-8, -1)
x1 = 0 ; y1 = 4
x2 = - 8 ; y2 = - 1
Slope, m = rise / run
Rise = y2 - y1 = - 1 - 4 = - 5
Rise = x2 - x1 = - 8 - 0 = - 8
The slope, m = - 5 / - 8
Slope, m = 0.625

put them in order from the least to greatest. You can use the number line to help!!
Answer:
-1 4/5, -1.7, -1 1/10, -1.
Step-by-step explanation:
We convert all of these to tenths. -1 4/5 becomes - 1 8/10. -1.7 becomes -1 7/10. -1 1/10 is already in tenths and -1 is a whole number. When putting these from least to greatest, remember that the bigger the negative, the less the number is.
