Step-by-step explanation:

B) data summary its in the words it sums up the answers to all the data you've collected over timew

Notice that

(x - 1)²/4 + (y + 2)²/9 = (2 sin(θ))²/4 + (3 cos(θ))²/9

… = sin²(θ) + cos²(θ)

… = 1

Solve for y in terms of x :

(x - 1)²/4 + (y + 2)²/9 = 1

(y + 2)²/9 = 1 - (x - 1)²/4

(y + 2)² = 9 - 9/4 (x - 1)²

y + 2 = ± √(9 - 9/4 (x - 1)²)

y + 2 = ± 3/2 √(4 - (x - 1)²)

y = -2 ± 3/2 √(4 - (x - 1)²)

In order for the square root to be defined, one needs

4 - (x - 1)² ≥ 0

(x - 1)² ≤ 4

-2 ≤ x - 1 ≤ 2

-1 ≤ x ≤ 3

so x must belong to the interval [-1, 3].

Answer:

[tex](x+6)(x-6)[/tex]

Step-by-step explanation:

Hi there!

The difference of squares theorem states that [tex]a^2-b^2=(a+b)(a-b)[/tex].

We're given:

[tex]x^2-36[/tex]

This can be rewritten since 36 is a perfect square:

[tex]=x^2-6^2[/tex]

Use the difference of squares theorem:

[tex]=(x+6)(x-6)[/tex]

I hope this helps!

Answer:

(x-6)(x+6)

Step-by-step explanation:

x^2 -36

Rewriting

x^2 - 6^2

We know a^2 - b^2 = (a-b)(a+b)

(x-6)(x+6)

Answer:

162/9 = 18 minutes

Step-by-step explanation:

50 m

Step One: Every rectangle, opposite side are equal sides.

Area=2, the area of this rectangle is 2*(l+b).

Step Two: Simplify the numbers: 2*(l+b) is also equal to 2*(20+5) and 2*(20+5) is equal to 2*25, so:

50 meters.

Both vertex angles will be same as its an isosceles triangle

Let each be x

According to angle sum property

[tex]\\ \sf \longmapsto x+x+50=180[/tex]

[tex]\\ \sf \longmapsto 2x+50=180[/tex]

[tex]\\ \sf \longmapsto 2x=180-50[/tex]

If I is not the midpoint of HJ, then it may lie any where on the line HJ and may not lie on HJ.

So, sometime i.e when I lies on HJ, H , I and J are collinear

Step-by-step explanation:

Answer:

q = -2

Step-by-step explanation:

-18q + 10q + 16q - 3 = -19

~Combine like terms

8q - 3 = -19

~Add 3 to both sides

8q = -16

~Divide 8 to both sides

q = -2

Answer:

y = 3x+6

Step-by-step explanation:

refer to the picture

Answer:

y = 3x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, so slope of parallel line is 3

Expressing the equation in point- slope form with m = 3 , (x₁, y₁ ) = (1, 9)

y - 9 = 3(x - 1)

y - 9 = 3x - 3 ( add 9 to both sides )

y = 3x + 6 ← in slope- intercept form

Answer:

322

Step-by-step explanation:

We have,

a^3+b^3=(a+b)^3-3ab(a+b)

p+1/p=7

Now,

p^3+1/p^3=(p+1/p)^3-3*p*1/p(p+1/p)

               =7^3-3(7)=343-21=322

The answer ; √ –108 = √108 × √–1 = 6i √3

Answer: x = 2

Step-by-step explanation:

Given

(1/4) (8x + 12) - 4x = -1

Expand parentheses

(1/4) (8x) + (1/4) (12) - 4x = -1

2x + 3 - 4x = -1

Combine like terms

-2x + 3 = -1

Subtract 3 on both sides

-2x + 3 - 3 = -1 - 3

-2x = -4

Divide -2 on both sides

-2x / -2 = -4 / -2

x = 2

Hope this helps!! :)

Answer:

x = 25°

Step-by-step explanation:

The 2 angles are vertical angles and are congruent , then

2x + 100 = 150 ( subtract 100 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25°

Answer: x = 25°

Step-by-step explanation:

⇒2x + 100 = 150

⇒2x = 150-100

⇒x = 50/2

⇒x = 25

Reason (VOA) vertically opposite angles are equal.

7.59

Step-by-step explanation:

The decimal can be from 7.55-7.64

When the range of the decimal is from 1-4, 5-9 during rounding it then the value will change to 7.6

Like 7.64, 7.63,7.62,7.61 will be rounded off to 7.6

And 7.55,7.56,7.57,7.58,7.59 will be rounded off to 7.6 too
