Answer:
x = 12√2
y = 12√2
Step-by-step explanation:
By applying cosine rule in the given triangle,
cos(45)° = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{y}{24}[/tex]
y = [tex]\frac{24}{\sqrt{2}}[/tex]
y = [tex]12\sqrt{2}[/tex]
By applying sine rule in the given triangle,
sin(45°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{x}{24}[/tex]
x = [tex]\frac{24}{\sqrt{2}}[/tex]
x = [tex]12\sqrt{2}[/tex]

y varies inversely with x. If y = 4 when x= -6, find the constant of variation and find the value of y when x= -2
Answers
Answer:
constant of variation: k = -24
y = 12 when x = -2
Step-by-step explanation:
y varies inversely with x equation is: y = k/x
where 'k' if the constant of variation
plug in:
4 = k/-6
cross-multiply to get value of 'k' which is -24
plug in:
y = -24/-2
y = 12

If A is the set of all integers, choose the set B that will make the following statement false.B ⊆ A
B = {1, 2, 3}
B = {2.5, 3.5, 4.5}
B = {0}
B = {−4, −1, 0, 5, 10}
Answers
Answer:
B.
Step-by-step explanation:
The sets {1, 2, 3}, {0}, {-4, -1, 0, 5, 10} only include integers which makes the statement true. Since they are all integers they are all subsets.
Answer {2.5, 3.5, 4.5} does not include integers so therefore it is not a subset making the statement false.

x^2+19=10 solve algebraically
4x^2+3=43 solve algebraically
Answers
Answer:
[tex]a)\ x_1=-3i,\ x_2 =3i[/tex]
[tex]b)\ x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]
Step-by-step explanation:
Given equations:
[tex]a)\ x^2+19=10\\\\b)\ 4x^2+3=43[/tex]
A. x² + 19 = 10
Step 1: Subtract 19 from both sides.
[tex]\\\implies x^2+19-19=10-19\\\\\implies x^2=-9[/tex]
Imaginary number rule: For any positive real number "k", [tex]\sqrt{-k} = i\sqrt{k}[/tex]
Note: Two imaginary (complex) solutions indicate that the graph will not intersect the x-axis. As a result, it has no real roots.
Step 2: Take the square root of both sides (positive and negative roots).
[tex]\\\implies \sqrt{x^2}=\sqrt{-9}\\\\\implies x=\pm\ i\sqrt{9}\\\\\implies x=\pm\ 3i[/tex]
Step 3: Separate the solutions.
[tex]\implies x_1=-3i,\ x_2 =3i[/tex]
----------------------------------------------------------------------------------------------------------------
B. 4x² + 3 = 43
Step 1: Subtract 43 from both sides.
[tex]\\\implies 4x^2++3-3=43-3\\\\\implies 4x^2=40[/tex]
Step 2: Divide both sides by 4.
[tex]\\\implies 4x^2=40\\\\\implies \dfrac{4x^2}4=\dfrac{40}{4}\\\\\implies x^2=10[/tex]
Step 3: Take the square root of both sides (positive and negative roots).
[tex]\\\implies \sqrt{x^2}=\sqrt{10}\\\\\implies x=\pm\ \sqrt{10}[/tex]
Step 4: Separate the solutions.
[tex]\implies x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]
True or false? A theorem is a statement that can be easily proved using a
corollary.
Answers
Answer:
true
Step-by-step explanation:
Answer: False
explanation:
Its proof is not difficult because it is based on the statement or theorem which has been already proved. For example the fundamental theorem of algebra and its corollary. Therefore, the statement "A corollary is a statement that can be proved using a theorem, but the proof is usually difficult." is false
