Step-by-step explanation:
Step 1: Define
4h = 92
Step 2: Solve for h
Divide both sides by 4: h = 23Step 3: Check
Plug in h into the original equation to verify it's a solution.
Substitute in h: 4(23) = 92Multiply: 92 = 92Here we see that 92 does indeed equal 92.
∴ h = 23 is the solution to the equation.

What slope passes through the points (-1,5) and (3,-7) ?
A scientist observed a bacterium in a microscope. It measured about 0.0000029 meter in diameter. Which of the following is closest to 0.0000029?
A.
2×10−6
B.
2×10−5
C.
3×10−5
D.
3×10−6
Answer: A. [tex]2\times10^{-6}[/tex].
Step-by-step explanation:
Given: The diameter of bacterium = 0.0000029 meter
≈ 0.000002 meter [ with 6 decimal places]
[tex]=\dfrac{2}{1000000}=\dfrac{2}{10^6}[/tex]
[tex]=2\times10^{-6}[/tex] meters [[tex]\dfrac{1}{a^n}=a^{-n}[/tex]]
i.e. [tex]2\times10^{-6}[/tex] closest to 0.0000029.
Hence, the correct option is A. [tex]2\times10^{-6}[/tex].

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Point (7, 5)
Point (3, 5)
Step 2: Find slope m
Substitute: [tex]m=\frac{5-5}{3-7}[/tex]Subtract: [tex]m=\frac{0}{-4}[/tex]Divide: [tex]m=0[/tex]Answer:
0/-4
Step-by-step explanation:
You would us the slope formula: [tex]\frac{y2-y1 }{x2-x1}[/tex]
so y2 is 5 and y1 is 5 so 5-5= 0
then x2 is 3 and x1 is 7 so 3-7= -4
so the slope is [tex]\frac{0}{-4}[/tex]

Answer:
B = T - 9C/CA
Step-by-step explanation:
1. Switch the sides C(9+AB) = T
2. Divide both sides by C (get rid of what is least attached) C(9+AB)/C and T/C
3. Simplify the equation 9 + BA = T/C
4. Subtract 9, 9+ BA - 9 = T/C - 9
5. Simplify BA = T/C - 9
6. Divide both sides with A like you did with C

If k‐th term of a sequence is ak = ( -1) ^k(2-k)k/2k-1
,what is its next term ak+1 when k is even?
Given:
kth term of a sequence is
[tex]a_k=\dfrac{(-1)^k(2-k)k}{2k-1}[/tex]
To find:
The next term [tex]a_{k+1}[/tex] when k is even.
Solution:
We have,
[tex]a_k=\dfrac{(-1)^k(2-k)k}{2k-1}[/tex]
Put k=k+1, to get the next term.
[tex]a_{k+1}=\dfrac{(-1)^{k+1}(2-(k+1))(k+1)}{2(k+1)-1}[/tex]
If k is even, then k+1 must be odd and odd power of -1 gives -1.
[tex]a_{k+1}=\dfrac{(-1)(2-k-1)(k+1)}{2k+2-1}[/tex]
[tex]a_{k+1}=\dfrac{(-1)(1-k)(1+k)}{2k+1}[/tex]
[tex]a_{k+1}=-\dfrac{1^2-k^2}{2k+1}[/tex] [tex][\because (a-b)(a+b)=a^2-b^2][/tex]
[tex]a_{k+1}=-\dfrac{1-k^2}{2k+1}[/tex]
Therefore, the next term is [tex]a_{k+1}=-\dfrac{1-k^2}{2k+1}[/tex].

Translate (3,-5) down 2 units.
Then reflect the result over the x-axis.
What are the coordinates of the final point?
solve for x
|2x-4|+6=8
Solve for x
|2x -4| + 6 =8
subtract 6 from both sides, then solve
|2x - 4| = 2 and |2x -4| = -2
2x - 4 = 2 2x - 4 = -2
+4 +4 +4 +4
2x = 6 2x = 2
divide by 2 to isolate the variable
x = 3 x = 1

Answer:
The length of the third side of the triangle is 30.
Step-by-step explanation:
Here is the formula for the Pythagorean Theorem:
[tex]a^{2} + b^{2} = c^{2}[/tex]
The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!
We need to multiply 40 times 40 and 50 times 50.
40 times 40, or 40 squared, equals to 1600.
50 times 50, or 50 squared, equals to 2500.
[tex]c^{2} - b^{2} = a^{2}[/tex]
Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.
Answer:
30
Step-by-step explanation:
c=√a^2+b^2
a=√c^2-b^2 = √50^2-40^2 = 30

Answer:
x = 0.5
Step-by-step explanation:
Given
- 8.25x + 12 - 1.75x = 10.5x + 1.75 , that is
- 10x + 12 = 10.5x + 1.75 ( subtract 10.5x from both sides )
- 20.5x + 12 = 1.75 ( subtract 12 from both sides )
- 20.5x = - 10.25 ( divide both sides by - 20.5 )
x = 0.5

2. A baby gained 15 pounds from birth to his first birthday.
Write this amount as an integer.
which statement describes the graph of the function f(x)=x^2-1/x^2-2x+1
A. there is a hole at x=-1
B. there is a vertical asymptote at x=-1
C. the y-intercept is y=-1
D. there is a horizontal asymptote at y=-1
Answer:
The Y-intercept is -1
Step-by-step explanation:
M*thway is a pathway to many abilities some considered to be... unnatural
Statement (C) the y-intercept is y=-1 describes the graph of the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
[tex]\rm f(x) = \dfrac{x^2-1}{x^2-2x+1}[/tex]
The above function is a rational function.
The denominator cannot be zero
x² - 2x + 1 ≠ 0
(x - 1)²≠ 1
x ≠ 1
To find y-intercept plug x = 0
f(0) = -1
Thus, statement (C) the y-intercept is y=-1 describes the graph of the function.
