the area of a rectangular window is 6216 cm^2. if the length of the window is 84 cm, what is it's width?
Answers
Answer:
The answer is 74 cmStep-by-step explanation:
The area of a rectangle = length × width
Since we are finding the width
We have
[tex]width = \frac{area}{length} \\ [/tex]
From the question
area = 6216 cm²
length = 84 cm
The width is
[tex]width = \frac{6216}{84} \\ [/tex]
We have the final answer as
74 cmHope this helps you

Answer:
The solution is [tex]b=\frac{v}{nj}[/tex]
Step-by-step explanation:
To solve an equation for a variable, state this variable with coefficient 1 on the left side and all the other terms on the right side
Ex: 2x + 6y = 10, solve for x
Subtract 6y from both sides to move it to the right side2x + 6y - 6y = 10 - 6y2x = 10 - 6yDivide each term on both sides by 2 to make the coefficient of x = 1[tex]\frac{2x}{2}=\frac{10}{2}-\frac{6y}{2}[/tex]x = 5 - 3yLet us use the same way to solve the given equation for b
∵ v = bnj
→ Switch the two sides to put b on the left sides
∴ bnj = v
∵ n and j multiplied by b
→ Divide both sides by nj to move them from the left side to the right side
∴ [tex]\frac{bnj}{nj}=\frac{v}{nj}[/tex]
∴ [tex]b=\frac{v}{nj}[/tex]
The solution is [tex]b=\frac{v}{nj}[/tex]

PLS HELP ME ASAP!!!!!!!!! ill give thanks, and five stars
Answers
Answer:
A
Step-by-step explanation:
The additive inverse property states that if we have a number a, then:
[tex]a+(-a)=0[/tex]
Here, we have the equation:
[tex]2x=542[/tex]
And we divide both sides by 2:
[tex]2x/2=542/2[/tex]
To acquire:
[tex]x=271[/tex]
So, we did not use the additive inverse property since we didn't add anything.
Instead, we used the division property of equality by dividing both sides by 2.
So, our answer is A.

f(3) is ___
Answers
Answer:
f(3) is - 1
Step-by-step explanation:
f(3) means the function value when x = 3
3 is in the domain, the function value is in the range.
Thus when x = - 3 → y = - 1
f(3) is - 1
The value of given mapping diagram for function f(3) is - 1
What is Mathematical function ?
Mathematical function is the representation of relation between independent variables and dependent variables.
Here is given mapping diagram f(3) means the function value x = 3
3 is in the domain which is independent of range as shown in diagram.
Thus when x = 3 the range is approaching towards y = - 1
therefore, f(3) equals - 1

Write the equation for Axis of Symmetry (AOS) for: y = 2(x – 3)² + 4
Answers
Answer:
X=3
Step-by-step explanation:
The axis of symmetry is 3 because we already know the value of h and k from vertex equation also known as y=a(x-h)²+k when a≠0
If you want to know the equation of symmetry, it is -b/2a when a ≠ 0
[tex]\frac{-b}{2a}[/tex] But if we want to use this formula, we have to convert the vertex form into standard form.
[tex]y=2(x^2-6x+9)+4\\y=2(x^2-6x+9)+13\\y=2x^2-12x+9+13\\y=2x^2-12x+22[/tex]
Therefore, the standard form of y=2(x-3)²+4 is 2x²-6x+22
We can use the axis of symmetry formula or -b/2a
From the equation, b is -12 and a is 2. Substitute both b and a in the -b/2a
Thus, -(-12)/2(2) = 12/4 = 3 #
Therefore, the axis of symmetry is 3. Using the Axis of Symmetry Formula, -b/2a
