= 4x^2
find [t]-1 given that cos sin sin cos and show that [t]21 5[t]t and hence that [t] is an orthogonal matrix.
TT is equal to T-1, so the given matrix is an orthogonal matrix.
What is an orthogonal matrix?
A matrix is said to be orthogonal if its antipode is also its transpose and if its relationship to the inner product is established. A real square matrix with orthonormal vectors in its columns and rows is known as an orthogonal matrix or orthonormal matrix in direct algebra. Where QT is the transpose of Q and I is the identity matrix is one system to put this into words. However, the matrix is said to be orthogonal, If the transpose of a square matrix with real figures or values is equal to the inverse matrix of the matrix. In other words, an identity matrix will always be affected by the product of a square orthogonal matrix and its transpose.Here, the determinant of T,
|T| = cos²∅ + sin²∅
= 1
Now, its cofactors,
[tex]T_{11}[/tex] = cos ∅
[tex]T_{12[/tex] = sin ∅
[tex]T_{21[/tex]= -sin ∅
[tex]T_{22[/tex] = cos ∅
Now, the adjoint matrix of cofactors matrix transpose [tex]T^T[/tex] is equal to [tex]T^{-1.[/tex]
Hence, the given matrix is an orthogonal matrix.

The meal total was $50. If we leave a 20% tip, then what will the meal cost us total. (Hint: meal total plus tip = overall total: tip = meal x %(in decimal form)
Answer:
Total cost of meal is $60
Step-by-step explanation:
The cost of meal = $50
Tip = 20%
We need to find total cost of meal
First find 20% of 50 to get the amount given for tip
[tex]20\% \:of\: 50\\=\frac{20}{100}\times 50\\=10[/tex]
So, tip given is $10
Total cost of meal = 50+10 = $60
So, total cost of meal is $60

Find the value of 3v- 10 given that 2v- 7 = 9
Answer:
14
Step-by-step explanation:
2v - 7 = 9
Add 7 to both sides
2v = 16
Divide both sides by 2
v = 8
Plug it into 3v - 10
3v - 10 =

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..
Answer:
[tex]y > 3\cdot x + 5[/tex]
Step-by-step explanation:
Let [tex]A(x,y) = (-2,4)[/tex] and [tex]y = 3\cdot x + 5[/tex]. Now we evaluate the given function at [tex]x = -2[/tex]:
[tex]y = 3\cdot x + 5[/tex] (1)
[tex]y = 3\cdot (-2)+5[/tex]
[tex]y = -6 +5[/tex]
[tex]y = -1[/tex]
Which means that [tex]y[/tex] is less than the y-component of A. Therefore, the right answer is [tex]y > 3\cdot x + 5[/tex].
Bill deposits $3,000 into an account that pays simple interest at a rate of 3% per year. How much interest will he be paid in the first 4 years?
Answer:
The interest he will be paid in the first 4 years is $360
Step-by-step explanation:
The rule of the simple interest is I = Prt, where
P is the initial depositr is the rate in decimalt is the time∵ Bill deposits $3,000 into an account
∴ P = 3000
∵ The account pays simple interest at a rate of 3% per year
∴ r = 3% = 3 ÷ 100 = 0.03
∵ The time is 4 years
∴ t = 4
→ Substitute these values in the rule above
∵ I = 3000(0.03)(4)
∴ I = 360 dollars
∴ The interest he will be paid in the first 4 years is $360

this is the equation:
-5x+12-7x=-3(5x+8)
thanks
Answer: X = -12
Step-by-step explanation:
-5x+12-7x=-3(5x+8)
To solve this, first open the bracket.
-5x+12-7x= -15x - 24
Then, collect like terms
-5x + 15x - 7x= -24 - 12
3x = -36
x = -36/3
x = -12

Answer:
[tex]c > 0\\t>0\\c+t\geq 60[/tex]
[tex]6c+4t\leq300[/tex]
Step-by-step explanation:
Given that:
[tex]c[/tex] represents the number of cucumber plants
[tex]t[/tex] represents the number of tomato plants
Now, as per the question statement, we can write the inequalities.
The students need to plant some of each plants and at least 60 plants.
i.e.
[tex]c > 0\\t>0\\c+t\geq 60[/tex]
Area required to plant each cucumber plant = 6 sq ft
Area required to plant each tomato plant = 4 sq ft
Area required to plant [tex]c[/tex] cucumber plants = 6[tex]c[/tex] sq ft
Area required to plant [tex]t[/tex] tomato plants = 4[tex]t[/tex] sq ft
Total area is at the maximum 300 square feet
[tex]6c+4t\leq300[/tex]
Therefore, the inequalities to represent the situation are:
[tex]c > 0\\t>0\\c+t\geq 60[/tex]
[tex]6c+4t\leq300[/tex]

What is the equation of the line that is horizontal and passes through point (−7.8, 2.9)? Answer: __________
Answer:
y = 2.9
Step-by-step explanation:
Horizontal lines have the same y-values for any x-value, so if the line passes through the point (-7.8, 2.9) it must have the same y-value of 2.9 for every other x-value, hence y = 2.9

Use the given information to find f(x + 1)
g(x) − f(x) = −2x + 5, g(x) = 5x − 3
Answer:
[tex]\mathbf{ f(x+1)=7x-1}[/tex]
Step-by-step explanation:
We need to find f(x+1)
We are given:
[tex]g(x) - f(x) = -2x + 5\:and\:g(x) = 5x -3[/tex]
First we need to find f(x)
By putting value of g(x) into g(x)-f(x)
[tex]g(x) - f(x) = -2x + 5\\\Put\:value\:of\:g(x) = 5x -3\\5x-3-f(x)=-2x+5\\-f(x)=-2x+5-5x+3\\-f(x)=-2x-5x+5+3\\-f(x)=-7x+8\\f(x)=-(-7x+8)\\f(x)=7x-8\\[/tex]
We have, [tex]f(x)=7x-8[/tex]
Now finding f(x+1) by putting x=x+1
[tex]f(x)=7x-8\\Put\:x=x+1\\f(x+1)=7(x+1)-8\\f(x+1)=7x+7-8\\f(x+1)=7x-1[/tex]
So, [tex]\mathbf{ f(x+1)=7x-1}[/tex]
