Which choice is equivalent to the product below for acceptable values of X?
sqrt(x+2)*sqrt(x-2)
Answer:
√x^2-4
Step-by-step explanation:
Given the expression
√(x+2) * √(x-2)
= √(x+2)(x-2)
Expand
= √x(x)-2x+2x-2(2)
= √x^2-4
Hence the product of the expression will give √x^2-4
For x to be acceptable x^2 - 4 = 0
x^2 = 4
x = ±√4
x = ±2
Acceptable value of x are values that are greater than or equal to ±2
Answer:
√x^2-4

Your social media ad costs $2.50 per thousand impressions. You get 3.14 million impressions. What is your approximate bill?
Answer:
7,850
Step-by-step explanation:
The approximate bill of impression is $7850.
What is multiplication?A mathematical arithmetic operation is a multiplication. Moreover, it is the practice of repeatedly adding the same expression kinds.
Example: 2 + 3 means that 2 is multiplied by 3 or that 3 is multiplied by 2 times.
Given:
Your social media ad costs $2.50 per thousand impressions.
You get 3.14 million impressions.
In a million,
there are 1000 of thousand in million.
So, there are 1000 times 3.14 of thousand impressions.
The amount in the bill,
= 3.14 x 1000 x 2.5
= $7850
Therefore, the bill is $7850.

Hello
Can you help me to do these two exercises please I block on those please it is on the derivatives of a number
Thank you so much in advance!!!
Answer:
First rememeber that if we have a function like:
g(x) = x^n
then:
dg(x)/dx = g'(x) = n*x^(n - 1)
And also if we have:
g(x) = f(x) + h(x)
then:
dg(x)/dx = g'(x) = f'(x) + h'(x)
1) We have the function f(x) = (x + 1)^2
We can rewrite this as:
f(x) = x^2 + 2*x + 1
Using both things written above, we know that:
f'(x) = 2*x + 1*2 = 2*x + 2
And we want to find f'(-2), so we only need to evaluate the above function in x = -2, this is:
f'(-2) = 2*-2 + 2 = -4 + 2 = -2
f'(-2) = -2
b) I suppose that this refers to the inverse function of f(x)
An inverse function is such that:
g( f(x)) = x
f( g(x)) = x
For f(x) = (x + 1)^2
The inverse will be something that first cancels that square, and then subtracts 1.
Then:
g(x) = √x - 1
if we evaluate this in f(x) we get:
g( f(x)) = √(f(x)) - 1 = √(x + 1)^2 - 1 = (x + 1) - 1 = x
Then the inverse function of f(x) is:
g(x) = √x - 1
This can also be written as:
g(x) = x^(1/2) - 1
Then the derivative of this will be:
g'(x) = (1/2)*x^(1/2 - 1) = (1/2)*x^(-1/2) = (1/2)*(1/√x)
A ice skater jumped an turned 1 full circle in the air how many one degree angles did she turn through
solve
y=-x+3
y=x^2+1
Answer:
[tex] - x + 3 = {x}^{2} + 1[/tex]
[tex] {x}^{2} + x = 2[/tex]
Answer:
Step-by-step explanation:
1st y=-x+3
Let's solve for x.
y=−x+3
Step 1: Flip the equation.
−x+3=y
Step 2: Add -3 to both sides.
−x+3+−3=y+−3
−x=y−3
Step 3: Divide both sides by -1.
−x/−1= y−3/−1
Answer:
x=−y+3

True or False? The measure of a tangent-chord angle is twice the measure of
the intercepted arc inside the angle.
The statement made which says the tangent - chord angle is twice the measure of the intercepted arc inside the angle is FALSE.
According to the angle theorem, the angle formed by the intersection of the chord and tangent on a circle is twice the measure of the intercepted arc. This means that the intercepted arc is twice the measure of the angle formed and not the other way round.Therefore, the statement is False because the intercepted arc is twice the measure of the angle formed by the intersection of the chord and the tangent on the circle.

Given:
A train is traveling at a constant speed in miles per hour.
The table of value is:
Hours (x) Miles (y)
1 20
2 100
3 180
4 260
5 340
To find:
The equation for the given data table.
Solution:
It is given that the train is traveling at a constant speed in miles per hour. So, it is a linear relationship.
Choose any two point from the given table of value. Let the two points are (1,20) and (2,100). So, the equation of the line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-20=\dfrac{100-20}{2-1}(x-1)[/tex]
[tex]y-20=\dfrac{80}{1}(x-1)[/tex]
[tex]y-20=80(x-1)[/tex]
Add 20 on both sides.
[tex]y=80(x-1)+20[/tex]
[tex]y=80x-80+20[/tex]
[tex]y=80x-60[/tex]

You wre flying a drone at a height of twelve yards. It has traveled a horizontal of twenty eight. What is the angle of depression from the drones current location down to its starting point
Answer:
23.19°
Step-by-step explanation:
Given that,
The height of a drone = 12 yards
It has traveled a horizontal of 28 yards
We need to find the angle of depression from the drones current location down to its starting point. It can be calculated as :
[tex]\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})\\\\=\tan^{-1}(\dfrac{12}{28})\\\\=23.19^{\circ}[/tex]

What are the coordinates of the focus of the parabola? (x+1)2=−8(y−2) (−1, 2) (1, −2) (−1, 0) (−1, 1)
Answer:
[tex](x,y) = (-1,0)[/tex]
Step-by-step explanation:
Given
[tex](x+1)^2 = -8(y-2)[/tex]
Required
The coordinates of the focus
First, write the expression in form of: [tex]y=a(x-h)^2+k[/tex]
[tex](x+1)^2 = -8(y-2)[/tex]
[tex](x+1)^2 = -8y + 16[/tex]
[tex]-8y + 16 = (x+1)^2[/tex]
Subtract 16 from both sides
[tex]-8y = (x+1)^2 - 16[/tex]
Divide through by -8
[tex]y = -\frac{1}{8}(x+1)^2 - \frac{16}{-8}[/tex]
[tex]y = -\frac{1}{8}(x+1)^2 +2[/tex]
In this case:
[tex]a = -\frac{1}{8}[/tex]
[tex]-h = 1[/tex] [tex]h = -1[/tex]
[tex]k = 2[/tex]
The focus of the parabola is:
[tex](x,y) = (h,k + \frac{1}{4a})[/tex]
This gives:
[tex](x,y) = (-1,2 + \frac{1}{4*-\frac{1}{8}})[/tex]
[tex](x,y) = (-1,2 + \frac{1}{-\frac{1}{2}})[/tex]
[tex](x,y) = (-1,2 -2)[/tex]
[tex](x,y) = (-1,0)[/tex]

in AABC, the measure of angle A=x degree, the measure of angle B=(2x)degrees, and the measure of angle C=(6x+18)degrees. What is the measure of angle B?
Answer:
m<B: 36
Step-by-step explanation:
x + 2x + 6x + 18 = 180
9x + 18 = 180
9x = 162
x = 18
m<B:
2x
2(18)
36
Answer:
m<B=36°
Step-by-step explanation:
The sum of angles in a triangle add up to 180°.
That means the sum of m<A+m<B+m<C=180°
We're given that:
m<A=x°
m<B=(2x)°
m<C=(6x+18)°
we can substitute those values as m<A, m<B, and m<C
x+2x+6x+18=180
combine like terms
9x+18=180
subtract 18 from both sides
9x=162
divide by 9
x=18°
we found the value of x, but we're not done yet
The question asks to find m<B, which is 2x°
in that case, we can substitute our known value to find the measure of <B
m<B=2x°
m<B=2(18)°
m<B=36°
