Answer:
[tex](4^{-2})^5=\dfrac{1}{4^{10}}[/tex]
Step-by-step explanation:
The given expression is : [tex](4^{-2})^5[/tex]
We need to simplify the above expression.
We know that, [tex]x^{-a}=\dfrac{1}{x^a}[/tex]
or
[tex](4^{-2})^5=(\dfrac{1}{4^2})^5\\\\=\dfrac{1^5}{(4^2)^5}\\\\\because (x^b)^c=x^{b\times c}\\\\=\dfrac{1}{4^{10}}[/tex]
So, the simplified form of the given expression is [tex]\dfrac{1}{4^{10}}[/tex]. Hence, the correct option is (A).

A student argues that Y= X/9 does not represent a proportional relationship between X and because we need to multiply one variable by the same constant to get the other one and not divide it by a constant. Do you agree or disagree with this student?
Answer:
Disagree
Step-by-step explanation:
disagree. dividing by 9 is the same as multiplying by 1/9. we can look at the equation y = x/9 as y = 1/9x. also, y/x = 1/9 is constant for all corresponding values of x and y

(x – 2)2 + y2 = 4
(x + 2)2 + y2 = 4
(x – 2)2 + y2 = 0
(x + 2)2 + y2 = 0
Answer:
a. (x – 2)2 + y2 = 4
Step-by-step explanation:
edge 2021
The rectangular form of [tex]\mathbf{r = 4cos(\theta)}[/tex] is (a) [tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]
The polar coordinate is given as:
[tex]\mathbf{r = 4cos(\theta)}[/tex]
Multiply both sides of [tex]\mathbf{r = 4cos(\theta)}[/tex] by r
[tex]\mathbf{r \times r= 4cos(\theta) \times r}[/tex]
Evaluate
[tex]\mathbf{r^2= 4rcos(\theta) }[/tex]
As a general equation, we have:
[tex]\mathbf{x^2 + y^2 = r^2}[/tex]
Substitute [tex]\mathbf{x^2 + y^2 = r^2}[/tex] in [tex]\mathbf{r^2= 4rcos(\theta) }[/tex]
[tex]\mathbf{x^2 + y^2= 4rcos(\theta) }[/tex]
Also as a general equation, we have:
[tex]\mathbf{x = rcos(\theta)}[/tex]
So, [tex]\mathbf{x^2 + y^2= 4rcos(\theta) }[/tex] becomes
[tex]\mathbf{x^2 + y^2= 4x}[/tex]
Subtract 4x from both sides
[tex]\mathbf{x^2-4x + y^2= 0}[/tex]
Complete the square on x^2 - 4x
[tex]\mathbf{(x - 2)^2-2 + y^2= 0 + 2}[/tex]
Add 2 to both sides
[tex]\mathbf{(x - 2)^2 + y^2= 0 + 2+2}[/tex]
[tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]
Hence, the rectangular form of [tex]\mathbf{r = 4cos(\theta)}[/tex] is (a) [tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]

Answer:
0.05
Step-by-step explanation:
Given that:
Number of samples, n = 5
Proportion, p = 80% = 0.8
P(x = 2)
Using binomial distribution formula ;
P(X = x) = nCx * p^x * (1 - p)^(n-x)
P(x = 2) = 5C2 * 0.8^2 * (1 - 0.8)^(5-2)
P(x = 2) = 5C2 * 0.8^2 * 0.2^3
P(x = 2) = 10 * 0.64 * 0.008
P(x = 2) = 0.0512

Answer:
(6, - 9 )
Step-by-step explanation:
Given the 2 equations
6x + 2y = 18 → (1)
- 4x - 2y = - 6 → (2)
Adding the 2 equations term by term will eliminate the y- term, that is
2x + 0 = 12
2x = 12 ( divide both sides by 2 )
x = 6
Substitute x = 6 into either of the 2 equationsand solve for y
Substituting into (1)
6(6) + 2y = 18
36 + 2y = 18 ( subtract 36 from both sides )
2y = - 18 ( divide both sides by 2 )
y = - 9
solution is (6, - 9 )
x + 4y = 16
-X + 3y = -2
Answer:
(8, 2 )
Step-by-step explanation:
Given the 2 equations
x + 4y = 16 → (1)
- x + 3y = - 2 → (2)
Adding the 2 equations term by term will eliminate the x- term
0 + 7y = 14
7y = 14 ( divide both sides by 7 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (1)
x + 4(2) = 16
x + 8 = 16 ( subtract 8 from both sides )
x = 8
solution is (8, 2 )

find angle X on the given figure. m
Answer:
x = 51°
Step-by-step explanation:
In a rhombus, the diagonals bisect the angles, thus
∠ BAE = ∠ DAE = 39° , then ∠ A = 78°
∠ ADE = ∠ CDE = x , then ∠ D = 2x
In a rhombus, consecutive angles are supplementary
∠ A and ∠ D are consecutive angles , thus
78 + 2x = 180 ( subtract 78 from both sides )
2x = 102 ( divide both sides by 2 )
x = 51°

If DE = 16x - 3, EF = 9x + 11, and DF = 52, find HG.
*see attachement for diagram
Answer:
HG = 25.6
Step-by-step explanation:
Given:
DE = 16x - 3
EF = 9x + 11
DF = 52
Required:
HG
SOLUTION:
✔️First, find the value of x
Thus, since DE is congruent to EF, therefore:
16x - 3 = 9x + 11
Collect like terms
16x - 9x = 3 + 11
7x = 14
Divide both sides by 7
x = 2
✔️Find EH:
Since diagonals of a rhombus are perpendicular, therefore ∆EHF is a right triangle.
Thus, we would use pythagorean theorem to find EH
EH² = EF² - HF²
EF = 9x + 11
Plug in the value of x
EF = 9(2) + 11 = 18 + 11
EF = 29
HF = 52/2 = 26 (diagonals bisect each other)
EH² = 29² - 26² = 165
EH = √165
EH = 12.8 (nearest tenth)
✔️Find HG:
HG = 2(EH) (diagonals bisect each other)
HG = 2(12.8)
HG = 25.6
The measure of HG is 25.6

Given the following information
DE = 16x - 3EF = 9x + 11DF = 52,
First, find the value of x
Since DE is congruent to EF, therefore:
16x - 3 = 9x + 11
Collect like terms
16x - 9x = 3 + 11
7x = 14
x = 2
Find the measure of EH:
Since the diagonals of a rhombus are perpendicular, therefore ∆EHF is a right triangle.
Thus, we would use Pythagorean theorem to find EH
EH² = EF² - HF²
EF = 9x + 11
Plug in the value of x
EF = 9(2) + 11 = 18 + 11
EF = 29
HF = 52/2 = 26 (diagonals bisect each other)
EH² = 29² - 26² = 165
EH = √165
EH = 12.8 (nearest tenth)
Find the measure of HG:

Find the roots of the equation 3x^2 - 2x + 4 = 2x^2 - 4 in simplest form
Answer:
3 x 2 − 2 x + 4 = 2 x 2 − 4
Step-by-step explanation:
Write the problem as a mathematical expression.
3 x 2 − 2 x + 4 = 2 x 2 − 4
Subtract 2 x 2 − 4 from both sides of the equation.
3 x 2 − 2 x + 4 − 2 x 2 − 4 = 0
Simplify each term.
Subtract 4 from 2 . 3 x 2 − 2 x + 4 − 2 x − 2 = 0
Rewrite the expression using the negative exponent rule
b − n =1 b n . 3 x 2 − 2 x + 4 − 2 1 x 2 = 0
Combine − 2 and 1 x 2 . 3 x 2 − 2 x + 4 + − 2 x 2 = 0
Move the negative in front of the fraction.
3 x 2 − 2 x + 4 − 2 x 2 = 0

Step-by-step explanation:
The x-axis is the horizontal line. In this case, if you are reflecting over the x-axis, you are flipping the sign of the y-coordinate.
Same with the y-axis. If you are reflecting over the y-axis, you are flipping the sign of the x-coordinate.
In this case, reflect across the x-axis. Flip the sign of the y: (x , y)
(-4 , -8) reflected over the x-axis is (-4 , 8).

A piece of wire is 76cm long. It is cut into two unequal parts and each part is bent into a square. The sum of the areas of the two squares is 205cm². Find the length of the shorter part of the wire.
Answer:
The length of the shorter part of the wire is 24 centimeters.
Step-by-step explanation:
Let [tex]L[/tex] the total length of the piece of wire, where [tex]L-x[/tex] and [tex]x[/tex] are the perimeters of the greater and lesser squares. All lengths are measured in centimeters. Since squares have four sides of equal length, the side lengths for the greater and lesser squares are [tex]\frac{L-x}{4}[/tex] and [tex]\frac{x}{4}[/tex]. From statement we find that the sum of the areas of the two squares ([tex]A[/tex]), measured in square centimeters, is represented by the following expression:
[tex]A = \left(\frac{L-x}{4} \right)^{2}+\left(\frac{x}{4} \right)^{2}[/tex] (1)
And we expand this polynomial below:
[tex]A = \frac{L^{2}-2\cdot L\cdot x +x^{2}}{16} + \frac{x^{2}}{16}[/tex]
[tex]A = \frac{L^{2}-2\cdot L\cdot x +2\cdot x^{2}}{16}[/tex]
[tex]2\cdot x^{2}-2\cdot L\cdot x +L^{2}-16\cdot A = 0[/tex] (2)
If we know that [tex]L = 76\,cm[/tex] and [tex]A = 205\,cm^{2 }[/tex], then the length of the shorter part of the wire is:
[tex]2\cdot x^{2}-152\cdot x +2496 = 0[/tex]
By the Quadratic Formula, we determine the roots associated with the polynomial:
[tex]x_{1} = 52\,cm[/tex], [tex]x_{2} = 24\,cm[/tex]
The length of the shorter part of the wire corresponds to the second root. Hence, the length of the shorter part of the wire is 24 centimeters.

It is 30°x60° right triangle
It has sides a against 30° angle, √3a against 60° angle and 2a hypotenuse
Vertical leg = 1Horizontal leg = √3Hypotenuse = 22. WHICH ONE DOESN'T BELONG? Which circle does not belong with the other three? Explain your reasoning ( 6 in. 12 in. 1 ft 6 in.
The first circle doesn't belong to the other three as it has a radius in it whereas the other circles have a diameter.
Circle 4 is different from other other Circles.
What is radius and Diameter of Circle?The radius of a circle is the distance from the center of the circle to any point on its circumference. The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circumference.
1. In Circle 1, the radius is 6 inch
So, Diameter= 6 x 2= 12 inch
2. In Circle 2, the diameter is 1 feet
Diameter = 1 feet = 12 inch
3. In Circle 3, the diameter is 12 inch
4. In Circle 4, the diameter is 6 inch.
Since, Circle 1, 2 and 3 have the diameter 12 inch but the Circle 4 have the diameter 6 ich.
Thus, Circle 4 is different from other other Circles.
