Answer:
A
Step-by-step explanation:
Given
[tex]\frac{m+2}{(m-4)^2}[/tex] - [tex]\frac{m-2}{(m-4)^2}[/tex]
Since the denominators are common then express as a single fraction
= [tex]\frac{m+2-(m-2)}{(m-4)^2}[/tex]
= [tex]\frac{m+2-m+2}{(m-4)^2}[/tex]
= [tex]\frac{4}{(m-4)^2}[/tex] → A
(a) An angle measures 27°. What is the measure of its complement?
(b) An angle measures 53°. What is the measure of its supplement?
measure of the complement:
X
$
measure of the supplement:
Please help
Answer:
a) 63°
b) 127°
Step-by-step explanation:
Complements are 90° while supplements are 180°.
So you need to find the complement of 27°. So, 90-27=63
To find the supplement, it is 180-53=127
In each problem 7 through 14, verify that each given function is a solution of the differential equation. Y" - y = 0; y1(t) = et, y2(t) = cosh t.
Answer:
Since L.H.S = R.H.S = 0, for both [tex]y_{1} (t) = e^{t}[/tex] and [tex]y_{2} (t) = cosh(t)[/tex], y₁ and y₂ both satisfy the equation y" - y = 0 and are thus solutions to the differential equation.
Step-by-step explanation:
To check whether the given functions are solutions the given differential equation, we differentiate the functions and then insert it into the given equation.
So y" - y = 0 and
[tex]y_{1} (t) = e^{t}\\y_{1}' (t) = e^{t}\\ y_{1}" (t) = e^{t}[/tex]
Substituting these values of y and y" into the left hand side of the equation, we have
y" - y
[tex]y_{1}" (t) - y_{1} (t) = e^{t} - e^{t} = 0[/tex]
Since L.H.S = R.H.S
So [tex]y_{1} (t) = e^{t}[/tex] is a solution of the differential equation.
When
[tex]y_{2} (t) = cosh(t)\\ y_{2}'(t) = sinh(t) \\y_{2}"(t) = cosh(t)[/tex]
Substituting y and y" into the left hand side of the equation, we have
y" - y
[tex]y_{2}"(t) - y_{2} (t) = cosh(t) - cosh(t) = 0[/tex]
Since L.H.S = R.H.S
So, [tex]y_{2} (t) = cosh(t)[/tex] is a solution of the differential equation.

3. A drone takes off from the base of a mountain at a height of 27 ft below sea level. The drone
then flies up 642 ft before landing at the top of the mountain. How tall is the mountain?
Answer:
669ft high
Step-by-step explanation:
642+27=669ft
The height of the mountain is 669 ft.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
For example 4 -2 = 2
A drone takes off from the base of a mountain at a height of 27 ft below sea level.
To determine the height of the mountain.
Using the arithmetic operations of addition and subtraction,
The drone then flies up 642 ft before landing at the top of the mountain.
Assume that distance below sea level is positive,
So the height of the mountain as
⇒ 642 + 27
⇒ 669 ft
Hence, the height of the mountain is 669 ft.

The sum of 6 consecutive integers is 339.
Answer:
54, 55, 56, 57, 58, and 59 are the numbers
Step-by-step explanation:
Let's pretend that the first number is [tex]n[/tex].
We know that these numbers are consecutive, meaning each number is one more than the other.
This means that
[tex]n + (n+1)+ (n+2)+ (n+3)+ (n+4)+ (n+5) = 339[/tex], since each number is consecutive.
We can combine like terms to get [tex]6n + 15 = 339[/tex].
Now let's solve for n.
[tex]6n + 15 - 15 = 339-15\\\\6n = 324\\\\n = 54[/tex]
So [tex]n=54[/tex]. This means the other 5 digits will be one more than the next.
So 54, 55, 56, 57, 58, and 59.

What is the value of x in the equation?
Answer:
[tex]x=56[/tex]
Step-by-step explanation:
So we have the equation:
[tex]\frac{2(x+4)}{3}-8=32[/tex]
First, add 8 to both sides. The left cancels:
[tex]\frac{2(x+4)}{3}=40[/tex]
Multiply both sides by 3. The left cancels:
[tex]2(x+4)=120[/tex]
Divide both sides by 2:
[tex]x+4=60[/tex]
Subtract 4 from both sides:
[tex]x=56[/tex]

A group project in an intro stats project looks at the cost of gasoline. Students recorded the cost per gallon at a nearby gas
station over a period of 10 weeks and want to make a time plot. What variable goes on the horizontal axis?
Choose the correct answer below.
Time (week 1 - Week 10)
Day of the week the cost was recorded (Sun - Sat)
Cost per gallon
Answer:
Time (week 1 - week 10)
Step-by-step explanation:
Given
Measure of cost of gasoline over a period of time
Required
Determine what variable belongs to the horizontal axis
To answer this question, I'll re-echo the given parameters again
Measure of cost of gasoline over a period of time
This can be rephrased to be
Measure of cost of gasoline with respect to time
This means that the cost of gasoline is a function of time (10 weeks, to be precise).
Hence;
Cost will be on the vertical axis
Time will be on the horizontal axis

Is the sum of two binominals is always a binomial? Why or why not?
Answer:
No
Step-by-step explanation:
Algebraic Terms:
1. Monomial - an algebraic term
2. Binomial - the sum of 2 algebraic terms
3. Trinomial - an algebraic sum in 3 terms
4. Polynomial - a function in more than 1 algebraic term
The sum of 2 binomials is not always a binomial because each of the two binomials might have different algebraic terms.
If the first binomial has 2 algebraic terms and the second binomial has 2 other algebraic terms and no single term crosses out its coefficients, the sum of both binomials will not be a binomial.

The solution set for this inequality is {x | x > 2}
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We also find the solution in a system of equations using the substitution or elimination method.
Example:
2x + 4 = 8
The solution is x = 2.
We have,
To solve the inequality:
2x - 3 > 11 - 5x
We can start by simplifying the expression on both sides:
2x - 3 > 11 - 5x
Adding 5x to both sides
7x - 3 > 11
Adding 3 to both sides
7x > 14
Dividing both sides by 7
x > 2
This means that any value of x greater than 2 will make the inequality true.
Thus,
The solution set for this inequality is {x | x > 2}

What is the point-slope form given the following slope and a point on the line? m = 3/7 , (7, -4)
Answer:
The equation is y = (3/7)x - 7.
Step-by-step explanation:
Given that the point slope form of an equation is y = mx + b where m represents the gradient and b is the y-intercept. Then, you have to substitute the following values into the equation :
[tex]y = mx + b[/tex]
[tex]let \: m = \frac{3}{7} ,x = 7,y = - 4[/tex]
[tex] - 4 = \frac{3}{7} (7) + b[/tex]
[tex] - 4 = 3 + b[/tex]
[tex] - 4 - 3 = b[/tex]
