Answer:
A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1
Step-by-step explanation:
Which statements are true? Mark all that apply. A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1. D If y³ = 16, the value of y is 2.
Solution:
a) y³ = 27
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛27
y = 3
Option A is correct
b) y³ = 64
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛64
y = 4
Option B is correct
c) y³ = 1
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛1
y = 1
Option C is correct
d) y³ = 16
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛16
y = 2.52
Option D is wrong

Answer:
Measure of segment JL is 20 cm.
Step-by-step explanation:
By applying geometric mean theorem in the given right triangle,
[tex]\frac{JM}{KM}=\frac{KM}{ML}[/tex]
[tex](KM)^2=(LM)(ML)[/tex]
[tex]8^2=(JM)(4)[/tex]
[tex]JM=\frac{64}{4}[/tex]
[tex]JM=16[/tex]
Since, [tex]JL=JM+ML[/tex] [By segment addition postulate]
[tex]JL=16+4[/tex]
[tex]JL=20[/tex] cm
Therefore, measure of segment JL is 20 cm.
Margaret works at a clothing store. Today she has sold only shirt and pants.The ratio of the number of shirts sold to the number of the items sold to 2/5. Which model shows this to ratio
Answer:
Shirt : Pant = 2 : 3 , & Pant : Shirt = 3 : 2 , Linear model can be used.
Step-by-step explanation:
Ratio of ' Number of shirts sold : Number of items sold' = 2 : 5
Let the common ratio be = x
Then, number of shirts sold = 2x. And, number of total items sold = 5x.
So, number of pants sold = Number of items sold - number of shirts sold = 5x - 2x = 3x
So, shirt to pant ratio = 2x / 3x = 2 : 3 .And, pant to shirt ratio = 3 : 2
This model can be shown in linear equation, as all are linear powered.

Answer:
Please find attached the required graph of the equation, y = x² - 2·x - 8, created using MS Excel
Step-by-step explanation:
The given function required to be plot is y = x² - 2·x - 8
Therefore, the coordinates of the vertex of the parabola formed by the equation (h, k) is given as follows;
h = -(-2)/(2×1) = 1
k = 1² - 2×1 - 8 = -9
The coordinates of the vertex = (1, -9)
The roots of the equation is given when y = 0, as follows;
At the roots, we have;
x² - 2·x - 8 = 0
By factorizing, we get
x² - 2·x - 8 = (x - 4)·(x + 2) = 0
Therefore. the roots of the equation are;
x = 4, and x = -2
The coordinates of the roots are;
(4, 0), and (-2, 0)
Two other points can be found at when x = 3 and when x = 0 as follows;
When x = 3, we have;
y = 3² - 2×3 - 8 = -5
(3, -5)
When x = 0, we have;
y = 0² - 2×0 - 8 = -8
(0, -8)
The five points are;
(1, -9), (4, 0), (-2, 0), (3, -5), (0, -8)
The graph of the equation created using MS Excel showing the five points is attached.
Parallel Lines & Transversal 2 please help
Answer:
m<UKJ = 80
Step-by-step explanation:
These angles are equal to each other because they're corresponding angles:
12x - 4 = 10x + 10
12x - 10x = 10 + 4
2x = 14
x = 7
m<UKJ:
12x - 4
12(7) - 4

Answer:
OC=48
RK=100
Step-by-step explanation:
We can use proportions to find both OC and RK.
[tex]\frac{OK}{KY} =\frac{OC}{RY}[/tex]
[tex]\frac{12}{24} =\frac{OC}{96}[/tex]
[tex]24OC=1152[/tex]
[tex]OC=48[/tex]
[tex]\frac{KC}{RK} =\frac{OK}{KY}[/tex]
[tex]\frac{50}{RK} =\frac{12}{24}[/tex]
[tex]12RK=1200[/tex]
[tex]RK=100[/tex]
Answer:
RK = 100
OC = 48
Step-by-step explanation:
Scale factor = 12/24 = 1/2
1/2 RK = 50
RK = 2* 50
RK = 100
1/2 RY = OC
1/2 * 96 = OC
48 = OC
OC = 48
