Final answer:
To produce an irrational number by multiplying by 1/5, the other number must be irrational, such as √2.
Explanation:
The student is asking which number, when multiplied by 1/5, produces an irrational number. To produce an irrational number by multiplication, the other number must itself be irrational. Because rational numbers multiplied by rational numbers yield rational results. A classic example of an irrational number is √2, which, when multiplied by 1/5, gives 1/5√2 or √2/5, both of which are irrational.

If f(x) = –x3, g(x) = 3x2 – 1, and h(x) = 2x + 5, what is the degree of [f o g o h](x)?
a-2
b-3
c-5
d-6
Answer:
Option d: 6
Step-by-step explanation:
Find f(g(h(x))).
h(x)=2x+5
g(h(x)) = 3(2x+5)^2 -1 (substitute h(x) in)
f(g(h(x)))= -[3(2x+5)^2 -1]^3 (substitute g(h(x)) in)
Since it asks for the degree of the function, that means we must look for the variable with the highest degree. In this case, after distributing and simplifying out the last equation, we will find that the variable x has the highest degree of x^6, or 6.

Larissa wants to inscribe a regular hexagon in a circle using only a compass and straightedge. She will construct a circle and finds its center. She will then perform the following steps.
Step 1: Plot a point on the circle to represent a vertex of the hexagon. Place the compass on this point and draw an arc to cut the circle. This represents the next vertex of the hexagon.
Step 2: Without adjusting the width of the compass, place the compass on this vertex and draw an arc to create the next vertex.
Step 3: Repeat the process to get a total of 6 vertices.
Step 4: Draw a line between successive pairs of vertices to form the regular hexagon.
What is the error in Larissa's construction?
A. She did not change the width of the compass when constructing the different vertices.
B. She did not set the width of the compass to the radius of the circle.
C. She did not set the width of the compass to the diameter of the circle.
D. She did not construct two perpendicular bisectors to construct two diameters of the circle.
Jayce’s insurance company pays for 90% of the cost of an ambulance ride, after he pays a $250 deductible. The ambulance ride costs $1400. How much would Jayce pay for an ambulance ride?
The amount which would Jayce pay for an ambulance ride for the claim to the Jayce’s insurance company is $365.
What is deductible amount?The deductible amount is the amount which has to be paid by the customer against an insurance lost.
This amount is subtracted from the insurance amount, which one is claimed against the claim.
Jayce’s insurance company pays for 90% of the cost of an ambulance ride, after he pays a $250 deductible.
As the ambulance ride costs $1400. Thus the ambulance cost after the deductible is,
[tex]C=1400-250\\C=1150[/tex]
Here, the Jayce’s insurance company pays for 90% of the cost of an ambulance ride. Thus, the 10 percent amount should be pay by the Jayce's.
Now, the amount which is left after the insurance company paid to Jayce's is,
[tex]A=\dfrac{10}{100}\times1150\\A=115[/tex]
Hence, the total amount paid by Jayce is,
[tex]A=115+250\\A=365[/tex]
Hence, the amount which would Jayce pay for an ambulance ride for the claim to the Jayce’s insurance company is $365.

Write an equation of the line with a slope of 2 that passes through the point (2,0)
Hence, the line with a slope [tex]2[/tex] that passes through the point [tex](2,0)[/tex] is
[tex]y=2x-4[/tex]
What is the line of equation?
The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.
The numerous points which together form a line in the coordinate axis are represented as a set of variables [tex]x, y[/tex] to form an algebraic equation, which is referred to as an equation of a line.
As we know the line of the slope is
[tex]y=mx+b[/tex]
where [tex]m[/tex] is the slope we have [tex]m = 2.[/tex]
So it would be
[tex]y=2x+b[/tex]
Given the point, [tex](2, 0)[/tex]
Now, we replace [tex]x[/tex] with [tex]2[/tex] and [tex]y[/tex] with [tex]0[/tex].
Now, we solve for [tex]b[/tex].
So,
[tex]0=2(2)+b\\b+4=0\\b=-4[/tex]
Since we get [tex]b = -4[/tex], we replace [tex]b = -4[/tex]
i.e., [tex]2x-4[/tex]
Hence, the line with a slope [tex]2[/tex] that passes through the point [tex](2,0)[/tex] is

Richard records the weight of his two pets in a table, as shown. After how many weeks were the pets the same weight? What was their weight at that time? Pet 1 Week Weight (grams) 0 400 2 800 Pet 2 Week Weight (grams) 0 500 2 700 At 1 week, they both weighed 600 grams. At 2 weeks, they both weighed 500 grams. At 3 weeks, they both weighed 650 grams. At 4 weeks, they both weighed 1,000 grams.
Answer:
After week 1 both the pets were having same weights of 600 gms.
Step-by-step explanation:
As given in the question weights of two pets are
Week weight of pet 1(in gm) weight of pet 2(in gm)
0 400 500
1 600 600
2 800 700
3 1000 700
In this table weights of the pets at 0 wk and 2 wk has been given only and we have calculated the weights by averaging their weights at 1 and 3 wk.
1). weight at 1 week = (weight at 0 wk + weight at 2 wk)/2
weight of pet 1 = (400+800)/2 = 600 gm
weight of pet 2 = (500 + 700)/2 = 600 gm
2).weight at 2 week = (weight at 1 wk + weight at 3 wk)/2
Therefore weight after 3 week = 2×weight after 2 week - weight after 1 week.
weight of pet 1 = 2×800 - 600 = 1600-600 =1000 gm
weight of pet 2 = 2×700 - 700 = 700 gm.
Now we have got the answer from the table formed that after 1 week both the pets were of same weight 600 gm.

Your Turn: In the diagram, AB = 12, DX = 2.5, and BX = 5. Find CD. Show all work.
Solution:
In ΔABX and ΔCDX,
∠CDX=∠ABX=90°
Also,∠CXD=∠AXB (as shown in figure)
∠DCX=∠BAX, as two angles of the triangle are equal. The third angle is also equal.
So ΔCDX≈ΔABX
Hence, the ratio of sides must be equal.
[tex] \frac{CD}{AB} =\frac{DX}{BX} =\frac{CX}{AX} [/tex]

Rectangle FGHJ is transformed according to the rule T(–3, –2)ry = x. What is the y-coordinate of J”?
Answer:
The y-coordinate of J'' is 8.
Step-by-step explanation:
The given rule of transformation is
[tex]T(-3,-2)r_{y=x}[/tex]
It means, first the figure is reflected across the line y=x and then translated by the rule T(-3,-2).
From the given figure it is clear that the coordinates of point J are (10,-6).
If a figure is reflected across the line y=x, then
[tex](x,y)\rightarrow (y,x)[/tex]
The coordinate of point J'.
[tex]J(10,-6)\rightarrow J'(-6,10)[/tex]
If a figure is translate by the rule T(-3,-2), then
[tex](x,y)\rightarrow (x-3,x-2)[/tex]
The coordinate of point J''.
[tex]J'(-6,10)\rightarrow J''(-6-3,10-2)=J''(-9,8)[/tex]
Therefore the y-coordinate of J'' is 8.

In right triangle PQR, P and Q are complementary angles. The value of sin Q is 9/41. What is the value of cos P?
Final answer:
In right triangle PQR, sin Q = 9/41. To find cos P, we need to determine the length of the hypotenuse PR. Once we have PR, we can use the cosine function to find cos P.
Explanation:
In a right triangle, the sine of an angle is the length of the side opposite the angle divided by the length of the hypotenuse. So, in triangle PQR, sin Q = opposite/hypotenuse = PQ/PR = 9/41.
Since angles P and Q are complementary, their sum is 90 degrees. Therefore, angle P = 90 - angle Q.
Now, using the Pythagorean theorem for triangle PQR (PQ^2 + QR^2 = PR^2), we can find PR. Since PQ = 9 and QR = 41, we have: 9^2 + 41^2 = PR^2. Solving for PR gives us PR ≈ 41.297.
Now that we have PR, we can find cos P using the cosine function: cos P = adjacent/hypotenuse = QR/PR = 41/41.297 ≈ 0.993.
In a right triangle, sin Q = 9/41. To find cos P, we can use the identity cos(90 - x) = sin(x). So cos P = sin(Q) = 9/41.
Explanation:In a right triangle, the sine of an angle is equal to the length of the side opposite the angle divided by the hypotenuse. In this case, sin Q = 9/41, which means that the length of the side opposite Q is 9 and the length of the hypotenuse is 41. Since P and Q are complementary angles, P = 90 - Q. Therefore, cos P = cos(90 - Q).
Using the identity cos(90 - x) = sin(x), we can substitute the value of Q to find cos P. cos P = sin(Q) = 9/41.
