rate,
how many word can he read each second?
Answer:
4 words per second
Step-by-step explanation:
To find out how many words he reads per second we need to divide both sides by 6. Doing this gives us 4 words per second.
Answer:
Timothy can read 4 words each second.
Step-by-step explanation:
Divide the amount of words he can read by the time it takes to read them.

What kind of lines are the two opposite sides of a rectangle?
parallel lines
perpendicular lines
neither
Answer:
They're parallel lines .
Step-by-step explanation:
But they are perpendicular to the lines they meet with. i.e; width lines are parallel to each other. But width lines are perpendicular to length lines.
[tex]{ \sf{}}[/tex]
Answer:
Parallel lines
Step-by-step explanation:
It wouldn't be perpendicular lines because a perpendicular line is when two lines come together to make a perfect corner, or 90 degree angle. It wouldn't be neither because parallel lines is when they face each other and if they were to go on forever they would never touch because they go straight. That may sound confusing but and example would be like the opposite lines on a square, how they're perfectly straight and opposite each other. The answer is parallel lines. Hope this helps! Good luck.

A coordinate plane with a straight line passing through the points (negative 6, negative 8) and (2, 8).
Use the formula m =m equals StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction to calculate the slope of the line.
The slope of the line is
.
Answer: 2 is correct
Step-by-step explanation:
The slope of the line passing through the points (-6, -8) and (2, 8) is 2.
Used the formula for the slope of the line passing through the points
(x₁ , y₁) and (x₂, y₂) would be,
[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Given that,
A coordinate plane with a straight line passing through the points (-6, -8) and (2, 8).
By using the above formula, the slope of the line is,
[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
[tex]m = \dfrac{(8 - (-8))}{(2 - (- 6))}[/tex]
[tex]m = \dfrac{(8 + 8)}{(2 + 6)}[/tex]
[tex]m = \dfrac{(16)}{(8)}[/tex]

Find the composition of the two functions and show your process:
f(g(x))
Answer:
[tex]x^2-6x+9[/tex]
Step-by-step explanation:
Say you have a function [tex]f(x)=x+1[/tex]. If you wanted to find f(3), you would replace the number in the parentheses, in this case 3, with x, to get [tex]f(3)=3+1=4.[/tex] When combining functions, you should do the same thing.
Here, we have [tex]f(x)=x^2.[/tex] We want to find f(g(x)). So, you should replace x in the function f(x) with the function g(x). [tex]g(x)=x-3.[/tex] So, f(g(x)) would equal [tex](x-3)^2[/tex], which equals [tex]x^2-6x+9[/tex].

Answer:
AM=1 false
BM= ½ true
AM=½ false
BM= √3/2 false
AM= ✓3/2 true
BM=1 false
Step-by-step explanation:
Since the triangle is equilateral it means that all sides are of the same length. So AB=1, BC=1, AC=1
AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM= ½ true because BC=1 so BM (half)=0,5=½
AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM= √3/2 false because it's ½
AM= ✓3/2 true because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM=1 false because BM= ½

The pH level, P, of a liquid can be determined from the hydronium ion (H3O+) concentration, c, using the equation P = –log(c). If the pH level of grape juice is 3.3, what is the hydronium ion concentration?
A. 5.01 x 10^–4
B. 1.19 x 10^–2
C. 1.99 x 10^3
D. 1.53 x 10^5
Logarithm involves the use of exponents to represent numbers.
If the pH level of grape juice is 3.3, the hydronium ion concentration is [tex]5.01 \times 10^{-4[/tex]
Given that:
[tex]P = -\log(c)[/tex]
To calculate c when [tex]P = 3.3[/tex]
We first substitute 3.3 for P in [tex]P = -\log(c)[/tex]
So, we have:
[tex]3.3 = -\log(c)[/tex]
Divide both sides by -1
[tex]-3.3 = \log(c)[/tex]
Apply law of logarithm
[tex]10^{-3.3)} = c[/tex]
Rewrite as:
[tex]c = 10^{-3.3}[/tex]
Using a calculator, we have:
[tex]c = 0.000501[/tex]
Rewrite as
[tex]c = 5.01 \times 10^{-4[/tex]
Hence, the hydronium ion concentration is [tex]5.01 \times 10^{-4[/tex]

Determine the domain and range of the polynomial function
9514 1404 393
Answer:
(b) domain: all reals; range: y ≤ 6
Step-by-step explanation:
The domain of any polynomial function is always "all real numbers." There are no values of the variable for which a polynomial is undefined.
The range of a polynomial will depend on its degree and the sign of the leading coefficient. Here, the degree is even, so the range has a limit. The leading coefficient is negative, so that limit is a maximum.
Only one answer choice has these characteristics:
domain: all real numbers; range: y ≤ 6

The graph confirms this choice of range.

Answer:
100 inch
Step-by-step explanation:

254 cm×0.394=100 inch
1in = 2.54cm
So you would divide 254cm by 2.54cm to see how many inches it would be equal to, and since 2.54 goes int 254 a hundred time 254cm equals 100in
