Mathematics
1 answer:
Tcecarenko [31]3 years ago
4 0

Answer:

y=6x-2 is perpendicular to the 6y=-x+7

y=6x+1 is parallel to the y=6x-2

Step-by-step explanation:

if product of two lines gradient is -1 than lines are perpendicular

gr y=6x-2

    y=mx+c m=gradient

1)m=6

2)m=-1/6

3)m=6

if gradients of 2 lines are equal they are paralel

kati45 [8]
4 rows and 6 seashells in each row. 
Row 1: 0 0 0 0 0 0
Row 2: 0 0 0 0 0 0
Row 3: 0 0 0 0 0 0
Row 4: 0 0 0 0 0 0

You add all of them together 6+6+6+6=24 
Or you could do 6x4 and your answer would be 24
So the answer to the question is 24 seashells.

What is the simplified expression for,
Nostrana [21]

Here are a few rules you need to know for this equation:

  • Multiplying exponents of the same base: x^m\times x^n=x^{m+n}
  • Dividing exponents of the same base: \frac{x^m}{x^n}=x^{m-n}
  • Turning a negative exponent to a positive one: x^{-m}=\frac{1}{x^m};\frac{1}{x^{-m}}=x^m

So this is our algebraic expression: \frac{3^{-4}\times 2^3\times 3^2}{2^4\times 3^{-3}}

Firstly, multiply 3^-4 and 3^2: \frac{3^{-4+2}\times 2^3}{2^4\times 3^{-3}}=\frac{3^{-2}\times 2^3}{2^4\times 3^{-3}}

Next, divide:

\frac{3^{-2}\times 2^3}{2^4\times 3^{-3}}=3^{-2-(-3)}2^{3-4}=3^12^{-1}

Next, turn the negative exponent into a positive one: 3^12^{-1}= \frac{3}{2}

<u>Your final answer is 3/2, or 1.5.</u>

Suppose a population of 40 crickets doubles in size every month. the function gives the population after x months. how many cric
Andreyy89
The function is given by:
f(x)=40(2)^x
where x is in months
he population after 3 years will be found as follows:
x=3 years=3×12=36 months
thus the population after 3 years will be:
f(36)=40(2)^36
f(36)=2.748779069×10^12
