(3x²y³)(-5xy^{4}z)When multiplying the variables, do you multiply the x by the x next to the y^{4}z, and the y with the y^{4}? I asked my teacher this question for a similar problem and he said not to. When I asked my dad for help with this problem, he said that you do and the answer is -15x^{3}y^{7}z. Which method is correct?

Answers

Answer 1

Answer: remember
x^m=x times itself m times

REMEMBER THAT MULCTIPLICATION IS COMMUTATIVE
a(bc)=(ab)c

so basically
(abc)(3ac)=a*b*c*3*a*c=a*a*c*c*b*3=3a^2bc^2
group and regroup and move around

so in your problem
(3x^2y^3)(-5xy^4z)=
(3)(x^2)(y^3)(-5)(x)(y^4)(z)=
(3)(-5)(x^2)(x)(y^3)(y^4)(z)=
(-15)(x^3)(y^7)(z)=
-15x^3y^7z

Answers

The number 84 is divisible by 2,3,4 and 6.

What is division?

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.

The numbers which divide 84 completely are:-

2 ⇒ 84 ÷ 2=24

3 ⇒ 84 ÷ 3=28

4 ⇒ 84 ÷ 4=21

6 ⇒ 84 ÷ 6=13

Hence, the numbers are 2,3,4 and 6.

Alissa is analyzing an exponential growth function that has been reflected across the y-axis. She states that the domain of the reflected function will change because the input values will be the opposite sign from the reflected function. Simon disagrees with Alissa. He states that if an exponential function is reflected across the y-axis, the domain will still be all real numbers.

Answers

Answer:

Consider the exponential function

$y=Ae^x$

-----------(1)

and when it is reflected across y axis , it's equation becomes

$y=Ae^(-x)$

--------------------------(2)

As, domain of a function is defined as the set of all values of x , for which y is defined.

So, for function 1, domain is set of all real numbers.That is , x∈[-∞ ,∞]

And for function 2, which is reflection of function 1, it's domain will also be set of all real numbers.That is , x ∈ [-∞, ∞]

So, Simon is correct between Alissa and himself, as he is saying if an exponential function is reflected across the y-axis, the domain will still be all real numbers is true statement.

Simon is correct because even though the input values are opposite in the reflected function, any real number can be an input.

Two crews are laying blacktop on a road. They start at the same time at opposite ends of a 18-mile road and work toward one another. One crew lays blacktop at an average rate of 0.4 mile a day faster than the other crew. If the two crews meet after 5 days, find the rate of each crew.

Answers

total road length is 36 miles.
If one crew’s rate is x miles/day, the other is 1.4x miles/day.
The collective distance per day is x+1.4x,
so in five days the distance is 5(x+1.4x).
Set that equal to the total distance:
5(x+1.4x)=36
simplify:
x+1.4x=7.2
x(1+1.4)=7.2
x(2.4)=7.2
x=3
