Add 1 and subtract 1, so that the expression won't change.
[tex]x^{4}+\frac{1}{x^{4}}-3=x^{4}+\frac{1}{x^{4}}-3 +1 - 1\\\\=x^{4}+\frac{1}{x^{4}} - 2 + 1\\\\= (x^{2})^{2} + (\frac{1}{x^{2}})^{2}- 2 *x^{2}*\frac{1}{x^{2}} - 1\\\\[/tex]
[tex]= (x^{2} -\frac{1}{x^{2}})^{2} - 1\\\\=(x^{2}-\frac{1}{x^{2}})^{2}- 1^{2}[/tex]
(a² - b²) = (a+b)(a - b)
Here a = x² - (1/x²) and b = 1
[tex]= [ (x^{2}-\frac{1}{x^{2}})+ 1 ] [ (x^{2} -\frac{1}{x^{2}} - 1 ][/tex]

You need 3 sticks of butter for every 24 cookies you bake.
Complete the table using equivalent ratios.
3. 24
16
5. 32
Step-by-step explanation:
3 sticks of butter make 24 cookies
which means we multiplied 3 by 8
then we devide 16 cookies by 8 which is 2 (as you did)
therefore 5 multiplied by 8 equals 40

consider the image that shows a tower anchored by a guy with the guy wire is attached at point b on the tower 119 feet above the ground and then anchored to the ground at point a 120 feet from the base of the tower.
Options are: A) sin0= 119/120, B) sin0= 120/119, C) sin0= 119/169, and D) sin0= 120/169
Answer:
119/169
Step-by-step explanation:
Answer:
sin0 = 119/169
Step-by-step explanation:
In trigonometry, the formula for sine is opposite/hypotenuse
To find the opposite, you find the angle and look what is right across from it. In this case 119 is right across from the angle.
And of course, our hypotenuse is 169.
Therefore, your answer is
Sin0 = 119/169
Use the Pythagorean Theorem to find the measure of the space diagonal line in the box

Pythagorean Theorem Formula: a? + b2 = 2
256 inches
257 inches
258 inches
(259 inches
Answer:
14.42inches
Step-by-step explanation:
Given the following
b = 5 in
c = 8in
we are to find the measure of the space diagonal line
Using the pythagoras theoreml
l^2 = b^2 + c^2
l^2 = 13^2 - 5^2
l^2 = 169 -25
l^2 = 144
l = 12in
To get the measure of the space diagonal line in the box, we will use the pythagoras theorem;
s^2 = l^2 + c^2
s^2 = 144 + 8^2
s^2 = 144 + 64
s^2 = 208
s= 14.42inches
Hence the required length ix 14.42inches

How do I find the midpoint M C(3,-5) and D(7,9)
Given:
The two points are C(3,-5) and D(7,9).
To find:
The midpoint M of the given points.
Solution:
We know that,
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using the midpoint formula, the midpoint of C(3,-5) and D(7,9) is
[tex]M=\left(\dfrac{3+7}{2},\dfrac{-5+9}{2}\right)[/tex]
[tex]M=\left(\dfrac{10}{2},\dfrac{4}{2}\right)[/tex]
[tex]M=\left(5,2\right)[/tex]
Therefore, the midpoint M of two points C(3,-5) and D(7,9) is (5,2).

Find the value of x.
Answer:
x = 30.74
Step-by-step explanation:
39 - 15 = 24
y^2 + 24^2= 36^2
y^2 + 576= 1296
y^2= 720
y= [tex]12\sqrt{5}[/tex]
15^2 + [tex]12\sqrt{5} ^{2}[/tex]= x^2
225 + 720 = x^2
x^2= 945
x = 30.74

[tex]y = \frac{1}{2} e^{x}[/tex] equation is represented by the given graph.
What is graph?
"Graph is defined as the representation of relation between two variables on the coordinate plane."
According to the question,
From the observation of the graph,
for x= 0
y- intercept = [tex]\frac{1}{2}[/tex]
a. [tex]y = \frac{1}{8} e^{x}[/tex]
Substitute x = 0 in the equation we get,
[tex]y = \frac{1}{8} e^{0}[/tex]
⇒ [tex]y = \frac{1}{8}[/tex]
Therefore,
Option (a) is not the correct answer.
b. [tex]y = \frac{1}{2} e^{x}[/tex]
Substitute x = 0 in the equation we get,
[tex]y = \frac{1}{2} e^{0}[/tex]
⇒ [tex]y = \frac{1}{2}[/tex]
which is same as graph value.
Hence, Option (b) is the correct answer.

Sine cannot be greater than 1.
The given conditions cannot form a triangle, there is no possible value of K.
What is sine law?In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
Given that, in a triangle Δ IJK, k = 64 inches, j = 17 inches and ∠J = 68°.
We need to find value of ∠K,
So, using the sine law,
Sin K / k = Sin J / j = Sin I /i
So,
Sin K / k = Sin J / j
Sin K / 64 = Sin 68° / 17
Sin K = 3.5
K = Sin⁻¹(3.5)
K = ERROR
Hence, the given conditions cannot form a triangle, there is no possible value of K.
