Considering the provided information, and that we must identify which of the provided options allow us to determine that the two triangles are similar, we obtain the following:

As the angle-angle similarity says that if two angles of one triangle are congruent with two angles of another triangle, then the triangles are similar.

Finally, we see that the only option that satisfies this statement is option D, since it indicates that two angles of the triangles are congruent. Therefore the correct option is D.

The value of  sector KL is 52

If JM and KN are two diamters of the circle,

then they intersect at the center

The sector JK and NM are equal

Thus,

The sector JN and KM are also equal

sector KM = sector KL + sector LM

Sector JN = Sector KM

sector JN = sector KL + sector LM

125 =  6x + 4 + 8x + 9

125 = 14x + 13

14x = 125 - 13

14x = 112

x = 8

sector KL = 6x + 4

= 6(8) + 4 = 48 + 4 = 52

Therefore, the sector KL is 52

According to the even and odd function rules, we found out that the function [tex]y=x^{3}-3[/tex] is neither even nor odd and the function [tex]y=2x^{3}-x[/tex] is an odd function.

It is given to us that the functions are -

B. [tex]y=x^{3}-3[/tex]

C. [tex]y=2x^{3}-x[/tex]

We want to determine each of the following functions is even, odd or neither.

To see if the function is even, we have to check if [tex]f(-x)=f(x)[/tex]

To see if the function is odd, we have to check if [tex]f(-x)=-f(x)[/tex]

B. Here, we have

[tex]y=x^{3}-3\\= > f(x)=x^{3}-3\\= > f(-x)=(-x)^{3}-3\\= > f(-x)=-x^{3}-3[/tex]

We see that [tex]f(-x)\neq f(x)[/tex]. This implies that the function is not even.

Also, [tex]f(-x)\neq -f(x)[/tex]. This implies that the function is not odd.

Therefore, this function is neither even nor odd.

C. Here, we have

[tex]y=2x^{3}-x\\= > f(x)=2x^{3}-x\\= > f(-x)=2(-x)^{3}-(-x)\\= > f(-x)=-2x^{3}+x[/tex]

We see that [tex]f(-x)\neq f(x)[/tex]. This implies that the function is not even.

However,

[tex]f(-x)=-2x^{3}+x\\= > f(-x)= -(2x^{3}-x)\\ = > f(-x)=-f(x)[/tex]

This implies that the function is odd.

Therefore, this function is odd.

Thus, the function [tex]y=x^{3}-3[/tex] is neither even nor odd and the function [tex]y=2x^{3}-x[/tex] is an odd function.

The triangles created by the measurements of options A, B and D have specific side lengths. Therefore, you cannot create more than one triangle.

However, for a triangle with acute angles measuring 45° and 45°, a countless number of similar triangles (triangles with the same shape but different sizes) can be created.

The correct choice is C.

In order to determine the number of nachos and lemonade sold, you first write the given situation in an algebraic way.

If x is the number of nachos and y the number of lemonades, then, you have:

2.50x + 2.25y = 112.50 cost of the nachos and lemonade sold

x + y = 94 nachos and lemonade sold

Next, solve the previous system.

Multiply the second equation by 2.50. Next, subtract the equation to the first one:

(x + y = 94)(2.50)

2.50x + 2.50y = 235

2.50x + 2.25y = 112.50

-2.50x - 2.50y = -235

-0.25y = -122.5

solve the previous equation for y:

y = -122.5/(-0.25)

y = 490

Next, replace the previous value of y into the expression x + y = 94 and solve for x:

x + y = 94

x + 490 =

This gives us:

Answer:

[tex](x,y,z)=\left(\; \boxed{-1,7,-4} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]

[tex](x,y,z)=\left(\; \boxed{1,-1,4} \; \right)\quad \textsf{(larger $x$-value)}[/tex]

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}x^2+z^2=17\\\;4x+y=3\\\;\;\;y+z=3\end{cases}[/tex]

To solve by the method of substitution, first rearrange the third equation to make y the subject:

[tex]\implies y=3-z[/tex]

Substitute this into the second equation and solve for z:

[tex]\begin{aligned}\implies 4x+(3-z)&=3\\3-z&=3-4x\\-z&=-4x\\z&=4x\end{aligned}[/tex]

Substitute the found expression for z into the first equation and solve for x:

[tex]\begin{aligned}\implies x^2+(4x)^2&=17\\x^2+16x^2&=17\\17x^2&=17\\x^2&=1\\x&=\pm1\end{aligned}[/tex]

Substitute the found values of x into the second equation and solve for y:

[tex]\begin{aligned}\implies x=-1 \implies 4(-1)+y&=3\\-4+y&=3\\y&=7\end{aligned}[/tex]

[tex]\begin{aligned}\implies x=1 \implies 4(1)+y&=3\\4+y&=3\\y&=-1\end{aligned}[/tex]

Substitute the found values of x into the derived expression for z and solve for z:

[tex]\begin{aligned}\implies x=-1 \implies z&=4(-1)\\z&=-4\end{aligned}[/tex]

[tex]\begin{aligned}\implies x=1 \implies z&=4(1)\\z&=4\end{aligned}[/tex]

Therefore, the solutions are:

[tex](x,y,z)=\left(\; \boxed{-1,7,-4} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]

[tex](x,y,z)=\left(\; \boxed{1,-1,4} \; \right)\quad \textsf{(larger $x$-value)}[/tex]

Answer:

Slope : -1

y = intercept : (0,31)

Step-by-step explanation:

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

total patients = 300

type A:

total patients = 90

favourable patients = 27

type B:

total patients = 124

favourable patients = 31

type AB:

total patients = 6

favourable patients = 6

type O:

total patients = 80

favourable patients = 0

Step 02:

empirical probability:

probability = favourable outcomes / total outcomes

probability (A) = 27/ 90 = 0.3

probability (B) = 31 / 124 = 0.25

probability (AB) = 6 / 6 = 1

probability (O) = 0 / 80 = 0

That is the full solution.
