Explain why the value of the sine ratio for an acute angle
of a right triangle must always be a positive value less
than 1.
The sine is defined as the length of the opposite side divided by the length of the hypotenuse, both of which are positive. Since dividing a positive number by a positive number results in a positive number, the sine must be positive.
Also, since the hypotenuse is the longest side of the triangle, the sine is equal to some positive number less than the length of the hypotenuse being divided by the length of the hypotenuse, resulting in a number less than 1.

Prove that Lydia is incorrect
Firat, calculate the slope (m)
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
Where:
\((x_1,y_1) = (5,19)\)
\((x_2,y_2) = (4,15)\)
So, we have:
\(m = \frac{15 - 19}{4 - 5}\)
\(m = \frac{-4}{-1}\)
\(m=4\)
The equation is then calculated using:
\(y - y_1 = m(x-x_1)\)
Where:
\((x_1,y_1) = (5,19)\) and \(m=4\)
This gives:
\(y - 19 = 4(x-5)\)
\(y - 19 = 4x-20\)
Make y the subject
\(y = 4x-20+19\)
\(y = 4x-1\)
The above shows the equation. Hence, the Lydia is correct

The amount natalya will spend constructing the patio with concrete and brick is $4320, the correct option is D.
We are given that;
The concrete portion of the patio cost=$3 per square
To construct and the brick portion of the patio cost= $6 per square
Now,
The area of a rectangle is given by length times width. The concrete portion of the patio is a rectangle with length 6 cm and width 3 cm. Using the scale, we can convert these to feet:
6 cm = 6 x 4 ft = 24 ft 3 cm = 3 x 4 ft = 12 ft
Therefore, the area of the concrete portion is:
24 ft x 12 ft = 288 ft^2
The brick portion of the patio consists of two identical rectangles with lenth 3 cm and width 6 cm. Using the scale, we can convert these to feet:
3 cm = 3 x 4 ft = 12 ft 6 cm = 6 x 4 ft = 24 ft
Therefore, the area of one brick rectangle is:
12 ft x 24 ft = 288 ft^2
Since there are two brick rectangles, the total area of the brick portion is:
2 x 288 ft^2 = 576 ft^2
Now we can multiply the areas by their costs per square foot to get the costs of each portion:
Concrete cost = $3 x 288 ft^2 = $864 Brick cost = $6 x 576 ft^2 = $3456
The total cost of constructing the patio is the sum of the costs of each portion:
Total cost = $864 + $3456 = $4320
Therefore, by area the answer will be $4320.

The New England Cheese Company produces two cheese spreads by blending mild cheddar cheese with extra sharp cheddar cheese. The cheese spreads are packaged in 12-ounce containers, which are then sold to distributors throughout the Northeast. The Regular blend contains 65% mild cheddar and 35% extra sharp, and the Zesty blend contains 75% mild cheddar and 25% extra sharp. This year, a local dairy cooperative offered to provide up to 8100 pounds of mild cheddar cheese for $1.30 per pound and up to 3500 pounds of extra sharp cheddar cheese for $1.50 per pound. The cost to blend and package the cheese spreads, excluding the cost of the cheese, is $0.30 per container. If each container of Regular is sold for $1.80 and each container of Zesty is sold for $2.10, how many containers of Regular and Zesty should New England Cheese produce
Answer:
They would produce 14,400 packages of zetsy and the regular profit making would be $11,340.
Step-by-step explanation:
12-ounce
regular = 65%
mild = 35%
extra sharp zesty blend = 75%
extra sharp mild = 25%
8,100 mild for = $1.30
3,500 extra sharp = $1.50
cost blend and package = $0.30
regular sold = $1.8
zesty = $2.10
first we calculate the cost of each product
conversion Of ounces to pounds:
1 pound = 16 ounces
regular cost:
12/16 pounds x 65% mild x $1.30
= 0.63375
12/16 pounds x 35% sharp x $1.50
= 0.39375
+ blend and package $0.30
total = $1.3275
contribution: $1.8 – $1.3275
= $0,4725
zesty cost:
12/16 pounds x 75% mild x $1.30
= 0.73125
12/16 pounds x 25% sharp x $1.50
= 0.28125
+ blend and package 0.30
total $1,3125
contribution: $2.10 – $1.3125
= $0,7875
to maximize profit:
profit = $0.4725Regular + $0.7875zetzy
adding the constraint:
mild = Regular x $0.4775 + Zetzy x $0.5625 = 8,100
and
sharp = Regular x $0.2625 + Zetzy x $0.1875 = 3,100
contribution generated by each product/pound:
Regular Zesty
CM $ 0.47250 $ 0.47250
Constrain resource
( pounds of mild) 0.48750 0.56250
CM per constrain $ 0.9692 $ 1.4000
Constrain resource
( pounds of sharp) 0.26250 0.18750
CM per constrain $ 1.80 $ 4.20
As zesty is better we produce as much as we can:
8,100 pounts / 0.5625 per cheese spreads: 14,400
check for possibilities of other constraint:
14,400 zesty packages x 0.1875 pounds each = 2,700 pounds
because it’s possible we only produce zetsy
profit = $0.4725 (0) + $0.7875 (14,400)
profit = $ 11,340

D
94%
The value of m ∠ABC=86° ,because of the cyclic quadrilaterals.
Hence, Option (B) is correct.
Since, We know that,
A cyclic quadrilateral is a four-sided polygon whose vertices all lie on a common circle.
The opposite angles of a cyclic quadrilateral have a total of 180°.
Hence, We can formulate;
m ∠ABC + m ∠ADC = 180°
m ∠ABC + 94° = 180°
m ∠ABC = 180° - 94°
m ∠ABC = 86°
Similarly, one can find m∠DCB
m∠DAB + m∠DCB = 180°
99° + m∠DCB = 180°
m∠DCB = 180° - 99°
m∠DCB = 81°
Hence, m∠ABC = 86°

A grocer wants to mix two kinds of candy. One kind sells for $2.00 per pound, and the other sells for $2.85 per pound. He wants to mix a total of 21 pounds and sell it for $2.05 per pound. How many pounds of each kind should he use in the new mix?
Let x be the number of pounds of the $2.00 candy and let y be the number of pounds of the $2.85 candy.
We know that in total the grocer wants 21 pounds, this can be express by the equation:
\(x+y=21\)We also know that the grocer wants the mix to cost $2.05 per pound. This condition can be express as:
\(\begin{gathered} 2x+2.85y=2.05\cdot21 \\ 2x+\text{2}.85y=43.05 \end{gathered}\)Hence we have the system of equations:
\(\begin{gathered} x+y=21 \\ 2x+2.85y=43.05 \end{gathered}\)To solve ithe system we solve the first equation for y:
\(y=21-x\)and we plug this value in the second equation:
\(\begin{gathered} 2x+2.85(21-x)=43.05 \\ 2x+59.85-2.85x=43.05 \\ -0.85=43.05-59.85 \\ -0.85x=-16.8 \\ x=\frac{-16.8}{-0.85} \\ x=19.76 \end{gathered}\)Now we plug the value of x in the expression for y we found earlier:
\(\begin{gathered} y=21-19.76 \\ y=\text{1}.24 \end{gathered}\)Therefore, the grocer needs 19.76 pounds of the $2.00 candy and 1.24 pounds of the $2.05 candy

\(x' = Ax\)
where x is a vector and A is a square matrix.
b) To determine the stability of the system obtained in part (a), we need to analyze the eigenvalues of matrix A.
If all eigenvalues have negative real parts, the system is stable.
If at least one eigenvalue has a zero real part, the system is neutrally stable.
If at least one eigenvalue has a positive real part, the system is unstable.
c) To compute the eigenvalues and eigenvectors of matrix A, we solve the characteristic equation
\(det(A - \lambda I) = 0\),
where λ is the eigenvalue and I is the identity matrix.
By solving this equation, we obtain the eigenvalues.
Substituting each eigenvalue into the equation
\((A - \lambda I)v = 0\),
where v is the eigenvector, we can solve for the eigenvectors.
d) Once we have computed the eigenvalues and eigenvectors of matrix A, we can construct the diagonalization relationship as follows:
\(A = PDP^{(-1)}\)
where P is a matrix whose columns are the eigenvectors of A, and D is a diagonal matrix whose diagonal elements are the eigenvalues of A.
To show that this relationship is valid, we can compute \(PDP^{(-1)}\) and verify that it equals A.

b. Which function has the greatest growth factor? Justify your response.
Answer:
A)
Function A: Exponential
Function B: Linear
Function C: Exponential
Function D: Exponential
B) Function A
Step-by-step explanation:
Function A: This is exponential because- (1, 3)(2,9)(3,27)
It is not going up by the same number each time. However, it is multiplying by 3 each time which means it is exponential.
Function B: This is linear because- (1, 64)(1, 80)(1, 96)
It is going up by 16 each time, (a constant number) which means it is linear.
Function C: This is exponential because- there is a curve, linear is always a straight line. But, this has a curve which means it is exponential.
Function D: This is exponential because- It is increasing by a percentage and not a constant number. It is increasing by 1% which means it is exponential.
The function that has the greatest growth factor is Function A because, Function A multiplies by 3 each time. Function B is linear, exponential functions always pass linear functions despite how "steep" they are. Eventually, the exponential function will surpass it. Function C is also exponential but is not as "steep" as Function A. Function A multiplies by 3 each time but Function C increases less. Function D is also exponential, and for the same reasons as Function C, Function A has the greatest growth factor.
