The sum of three consecutive even integers is 66. Which equation represents the scenario?
The correct option is:
d. x + (x+2) + (x+4) = 66
The scenario involves three consecutive even integers. Let's denote the first even integer as x, the second one as x+2 (since it is the next consecutive even integer), and the third one as x+4 (as it is two more than the second one).
The sum of these three consecutive even integers is given to be 66. Therefore, the equation that represents this scenario is:
x + (x+2) + (x+4) = 66
So, the correct option is:
d. x + (x+2) + (x+4) = 66
The probable question may be:
The sum of three consecutive even integers is 66. Which equation represents the scenario?
a. x=66
b. x+(x+1)+(x+2)=66
c. x+x+x=66
d. x+(x+2)+(x+4)=66
Which of the following are equivalent to the function y = 4cos x - 2? Check all that apply.
A. y = -4cos x + 2
B. y = 4sin(x +π/2 ) - 2
C. y = 4sin(x - π/2) - 2
D. y = 4cos(-x) - 2 ...?
Out of the given options, B (y = 4sin(x +ext{ extpi}/2 ) - 2) and D (y = 4cos(-x) - 2) are equivalent to the function y = 4cos x - 2, due to trigonometric identities and properties.
To determine which of the given options are equivalent to the function y = 4cos x - 2, we need to look at trigonometric identities and properties of cosine and sine functions.
Option A: y = -4cos x + 2 is not equivalent since it represents a reflection in the x-axis followed by a vertical shift, which alters the original function's graph completely.Option B: y = 4sin(x +rac{ext{extpi}}{2}) - 2 is equivalent because of the co-function identity sin(x + rac{ext{ extpi}}{2}) = cos x, which makes the functions identical.Option C: y = 4sin(x - rac{ext{extpi}}{2}) - 2 is not equivalent because sin(x - rac{ext{extpi}}{2}) is not equal to cos x.Option D: y = 4cos(-x) - 2 is equivalent due to the even property of the cosine function, which states that cos(-x) = cos x.
The graph of the function f(x) = (x – 4)(x + 1) is shown below. Which statement about the function is true? The function is increasing for all real values of x where x < 0. The function is increasing for all real values of x where x < –1 and where x > 4. The function is decreasing for all real values of x where –1 < x < 4. The function is decreasing for all real values of x where x < 1.5.
we have
[tex]f(x)=(x-4)(x+1)[/tex]
using a graph tool
see the attached figure
we know that
The function is increasing for all real values of x where [tex]x > 1.5[/tex]
and
The function is decreasing for all real values of x where [tex]x < 1.5[/tex]
therefore
Statements
case a) The function is increasing for all real values of x where x < 0
The statement is false
case b) The function is increasing for all real values of x where x < –1 and where x > 4
The statement is false
case c) The function is decreasing for all real values of x where –1 < x < 4
The statement is false
case d) The function is decreasing for all real values of x where x < 1.5
The statement is true
Answer:
The correct option is:
The function is decreasing for all real values of x where x < 1.5.
Step-by-step explanation:
We are given a function f(x) which is a product of two linear polynomial as:
[tex]f(x)=(x-4)(x+1)[/tex]
Now, we know that on multiplying the two linear polynomial we will obtain a quadratic polynomial.
So, the function f(x) will be represented as:
[tex]f(x)=x(x+1)-4(x+1)\\\\f(x)=x^2+x-4x-4\\\\f(x)=x^2-3x-4[/tex]
So, we will plot the graph of the function and check which statements about the function hold true.
1)
The function is increasing for all real values of x where x < 0.
This statement is false.
Since we get from the graph that function f(x) is decreasing for x<0.
2)
The function is increasing for all real values of x where x < –1 and where x > 4.
This option is incorrect as the function is decreasing for x<-1
whereas it is increasing for x>4.
3)
The function is decreasing for all real values of x where –1 < x < 4.
This option is incorrect.
Since, the function is both decreasing as well as increasing in the interval (-1,4).
4)
The function is decreasing for all real values of x where x < 1.5.
This option is correct.
Since it could be observed from the graph that the function is decreasing for x<1.5.

60% of what number is 13.5?
The required, 60 percent of 22.5 is equal to 13.5, as of the given condition.
What is percentage?The percentage is a way of expressing a fraction or a decimal number as a portion of 100. It is denoted by the symbol '%'. For example, the percentage of 0.75 can be calculated as 0.75 x 100% = 75%. In other words, we are expressing 0.75 as a fraction of 100.
Here,
To find out what number 60% of is equal to 13.5, we can use algebra. Let x be the number we are looking for. Then we can write:
60% of x = 13.5
We can convert 60% to a decimal by dividing by 100:
0.6x = 13.5
Finally, we can solve for x by dividing both sides of the equation by 0.6:
x = 13.5 ÷ 0.6
x = 22.5
Therefore, 60% of 22.5 is equal to 13.5.

Find the lim [(ln(x+5) - ln5) / x ] as x approaches 0
...?
To find the limit of the given expression [(ln(x+5) - ln5) / x ] as x approaches 0, we can apply L'Hospital's Rule.
Explanation:To find the limit of the given expression, we can use L'Hospital's Rule. Let's first rewrite the expression:
[ln(x+5) - ln(5)] / x
As x approaches 0, when plugging in 0, we get an indeterminate form of 0/0. So, we can apply L'Hospital's Rule:
lim [(ln(x+5) - ln5) / x ] as x approaches 0 = lim [(1/(x+5)) / 1]
= lim (1 / (x+5)) as x approaches 0
Since x approaches 0, the expression approaches 1 / (0+5) = 1/5.

To find the value of [tex]\( x \)[/tex] in the diagram, we need to apply the properties of similar triangles. Assuming the diagram shows two similar triangles with corresponding sides labeled, we can set up a proportion between the sides of the similar triangles.
Let's denote the sides of the smaller triangle as [tex]\( a \), \( b \), and \( c \)[/tex], and the corresponding sides of the larger triangle as [tex]\( ka \), \( kb \), and \( kc \),[/tex] where [tex]\( k \)[/tex] is the scale factor between the two similar triangles.
Given that one side of the larger triangle is 4 times the corresponding side of the smaller triangle, we have [tex]\( k = 4 \)[/tex].
Now, if we let [tex]\( a = 21 \)[/tex] (as per the options given), then the corresponding side of the larger triangle is [tex]\( ka = 4 \times 21 = 84 \).[/tex]
The problem states that the side labeled [tex]\( x \)[/tex] in the larger triangle corresponds to the side labeled [tex]\( 1 \)[/tex] in the smaller triangle. Therefore, we have the proportion:
[tex]\[ \frac{x}{ka} = \frac{1}{a} \][/tex]
Substituting the known values, we get:
[tex]\[ \frac{x}{84} = \frac{1}{21} \][/tex]
To solve for [tex]\( x \)[/tex], we cross-multiply:
[tex]\[ x \times 21 = 84 \times 1 \][/tex]
[tex]\[ 21x = 84 \][/tex]
Now, we divide both sides by 21 to isolate [tex]\( x \)[/tex]:
[tex]\[ x = \frac{84}{21} \][/tex]
[tex]\[ x = 4 \][/tex]

Use the Laplace transform to solve the given initial value problem. y' + 6y = e^4t ; y(0)=2 ...?
The Laplace transform method is applied to solve the differential equation y' + 6y = e^4t with the initial condition y(0)=2. After transforming, simplifying, and solving for Y(s), we use inverse Laplace transform to find the solution y(t) in the time domain.
Explanation:Laplace transform is a powerful tool in the field of mathematics used for solving differential equations. To solve the given initial value problem y' + 6y = e^4t ; y(0)=2, we can start by taking the Laplace transform of both sides of the equation.
The Laplace transform of y' is sY(s) - y(0) and the Laplace transform of y is Y(s). Therefore, the Laplace transform of y' + 6y gives sY(s) - y(0) + 6Y(s). Given that y(0)=2, this simplifies to sY(s) + 6Y(s) - 2.
On the right-hand side, the Laplace transform of e^4t is 1/(s-4). Thus, we have the equation sY(s) + 6Y(s) - 2 = 1/(s-4).
By solving for Y(s), we can find the inverse Laplace transform to get the solution y(t) in the time domain.
