Hey there!
Let's make an equation
⇒y = (a)(x)(z)
y = 80x = 5z = 8⇒ 80 = a(5)(8)
⇒ 80 = a(40)
⇒ 80 = 40a
Divide both sides by 40
⇒40a/40 = 80/40
⇒a = 80/40
Therefore, a = 2
Let's substitute into first equation
⇒y = (2)(16)(2)
y = 64
So, y = 64

The both original functions have a domain of ( -∝ , ∝ )
What are domain and range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) is a parabolic function where the domain of the function ranges from
And , domain of a parabolic function is all real numbers, which means that the function is defined for every possible input value
Hence , the domain is ( -∝ , ∝ )

square root of 70 is
rational or iftationet
Answer:
Step-by-step explanation:
It's Irrational.
sqrt(70) = sqrt(2 * 5 * 7)
You can't pull anything out of the right to leave the number under the root sign = to 1. That means that since all three roots are irrational, the whole number is irrational, In fact it takes only 1 number other than 1 left under the root sign to make the result irrational.
√50 = √(5 * 5 * 2)
The 5's will produce one number outside the root sign -- five. That makes the result
5√2 The result is irrational because √2 is irrational

Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 200 adults will attend. You are trying to raise 3800 and deciding how much to charger per adult and per child. List some possible combinations (round to the nearest hundredths place) ___per adult, 0$ per child 10 per adult, ___ per child ___per child, 5$per child
Answer:
Some of the possible combinations are;
1) $19 per adult, $0 per child
2) $10 peer adult, $9 per child
3) $14 peer adult, $5 per child
Step-by-step explanation:
The given information are;
The estimated number of adults to attend the fund raising dinner = 200 adults
The amount the fund raiser is trying to realize = 3800
Therefore, some of the possible combinations are;
1) 3800/200 = 19 per adult to give;
$19 per adult, $0 per child
2) Given that each adult is charged $10, we have;
Total amount from adults = $10 × 200 = $2000
The total amount to be raised from the children = The amount the fund raiser is to realize - (Total amount from adults)
∴ The total amount to be raised from the children = 3800 - 2000 = 1800
The total amount to be raised from the children = $1,800
If there are 200 children we have;
The amount charged per child = (The total amount to be raised from the children)/(The total number of children)
The amount charged per child = $1,800/200 = $9 per child
Therefore, we have;
$10 peer adult, $9 per child
3) If each of the 200 children are charged $5 each, we have;
The total amount to be raised from the children = $5 × 200 = $1,000
∴ The amount to be raised from adults = $3800 - $1000 = $2800
The amount to each adult is to be charged = $2800/200 = $14
Therefore, we have;
$14 peer adult, $5 per child.

E is the middle of [AC]
so AE = 1/2 x AC
then
4x = 1/2 * (6x + 5)
4x = 3x + 5/2
x = 5/2
x = 2,5
Answer:
[tex]x=\dfrac52[/tex]
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other. This means that the diagonals are divided into 2 equal parts by the other diagonal.
Therefore,
[tex]\implies AE =\dfrac12 AC[/tex]
[tex]\implies 4x=\dfrac12(6x+5)[/tex]
To solve:
multiply both sides by 2:
[tex]\implies 8x=6x+5[/tex]
subtract 6x from both sides:
[tex]\implies 2x=5[/tex]
divide both sides by 2:
[tex]\implies x=\dfrac52[/tex]
For solving a side in right triangles how do we know if it’s multiplying or dividing?
Explanation:
It can be misleading to try to think in terms of "multiplying" or "dividing". There is a tendency to try to remember a procedure for solving problems. It can be more useful to remember the relationships involved in a problem.
Once you have an equation based on the relationships, you make use of the rules of algebra to solve it. Sometimes multiplication is involved; sometimes division.
__
The trig relations are summarized in the mnemonic SOH CAH TOA. This is intended to remind you ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
__
The rules of algebra tell you that these equations can be multiplied by the denominator to eliminate the fractions:
Hypotenuse × Sin = Opposite
Hypotenuse × Cos = Adjacent
Adjacent × Tan = Opposite
Solving any of these equations may involve multiplication, or it may involve division, depending on what you have and what you're solving for.
__
In short, remember SOH CAH TOA and the general rules of solving equations. That will tell you whether you need to multiply or divide.
Solve for h:
h-(-2.22)=-7.851
Answer:
h= -10.071
Step-by-step explanation:
- times a - equals positive: h+2.22= -7.851
move the 2.22 to the right side and change the sign to a negative: h= -7.851 -2.22
subtract -7.851-2.22= -10.071
h= -10.071

5. Solve for n in the literal equation a(n-2)+5=b n
Step-by-step explanation:
1. d = rt
Divide t from both sides.
[tex]\frac{d}{t} = r[/tex]
2. PV = nRT
Divide P from both sides.
[tex]V = \frac{nRT}{P}[/tex]
3. [tex]\frac{x}{2} -g=a\\[/tex]
Add g to both sides.
[tex]\frac{x}{2}[/tex] = g + a

4. g[tex](h+\frac{3}{2} ) = 11[/tex]
Divide g from both sides.
[tex]h + 1.5 = \frac{11}{g}[/tex]

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left
So we can see it in diagram that force in upper direction and lower direction is same 100N so this force will be cancelled out
Now force in right side is 75N and in left side force is 10N
So net force = (75-10)=65N in right side
