Factor out the coefficient of the variable -3.6m + 10.8

Answer:

y = 10√16) = 40

Step-by-step explanation:

This says, "y is proportional to the square root of x."  We are told that y = 60 when x = 36.  Find the formula for this function.  Then, determine what value y will take on when x = 16.

y = k√x  becomes 60 = k√36, or 60 = 6k.  Then k must be 10, and the formula is y = 10√x.

If x = 16, y = 10√16) = 40

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 )

Answer:(8,2)

Step-by-step explanation:

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 )

Answer:

(-4 , 8)

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).

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).

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

For a square, all the sides of the square are equal

Given the following information

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:  

HG = 2(EH)  (diagonals bisect each other)

HG = 2(12.8)

HG = 25.6

Hence the measure of HG is 25.6

Answer:

w= -2

Step-by-step explanation:

4w+4=-4

    -4    -4

4w=-8

/4    /4

w=-2

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.

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.

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°

Answer:

m = 28

Step-by-step explanation:

The given expression is :

0.1(0.5m+6)=2

Step 1.

Use distributive property:

0.1(0.5m) +0.1(6) = 2

0.05 m+ 0.6 = 2

Step 2.

Subtract 0.6 both sides

0.05 m+ 0.6 -0.6= 2 -0.6

0.05 m = 1.4

or

0.5 m = 14

Step 3.

Divide both sides by 0.5

[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]

Gabi's third step is not correct. It should be m = 28 instead of m = 7.

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]

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
