Answer:

Length = 8

Breadth = 12

Step-by-step explanation:

Since Area = length * breadth

96 = (x+2)(x-2)

Since (a+b)(a-b) = a^2-b^2

(x+2)(x-2) = x^2-4

Therefore

x^2-4 = 96

x^2 = 100

x = +-10

Since x > 0

x = 10

Answer:

Step-by-step explanation:

1). [tex]-\frac{5}{12}[/tex] x = 0 ⇒ x = 0

2). 5,4 ( x + 6,3 ) = 0 ⇒ x + 6,3 = 0 ⇒ x = - 6,3

3). ( x - 3 )( x + 4 ) = 0 ⇒ x - 3 = 0 или x + 4 = 0 ⇒ x = 3 или x = - 4

4). 23,5 | x | = 0 ⇒ | x | = 0 ⇒ x = 0

Answer:

slope=2 y-intercept=4

80 >= -8(w-8)

Use distributive property:

80 >= -8w + 64

Subtract 64 from both sides:

16 >= -8w

Divide both sides by -8:

-2 >= w

Because the division was done using a negative value the inequality gets reversed:

w >= -2

Answer : w >= -2

Answer: 6

Step-by-step explanation:

Check the picture below.

First, you want to find the area of the entire thing first.

The length adds up to 14, the width to 10. Multiply and you get 140 as the total area.

Now to get rid of the flower bed is simple, 8 Multiply to 3 which makes 24, then divide by 2 which is 12. Substract 12 to 140 and you get 128.

The formula for a trapezoid is Area= (base1 +base2)/2 times height. Following this, and 5 and 7 which gets 12. divide 12 to 2 and you get 6. 6 times 10 is 60.

Subtract 60 to 128 and you get 68.

Using translation concepts, it is found that a 90º clockwise rotation of the triangle around the origin took place.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, considering the points on triangles ABC and A'B'C', the change is modeled by:

(x,y) -> (y, -x).

Which is a 90º clockwise rotation of the triangle around the origin.

Answer:

1/9

Step-by-step explanation:

First turn all the negative exponents into positive by flipping the fractions then plug in the given values.

(3/1)^2 * (1/x)^4 * y^2

Simplify to:

9 * 1/(x^4) * y^2

Plug in:

9 * 1/(3^4) * -1^2

Simplify:

9 * 1 * 1/(3^4) = 9/(3^4) = 9/81 = 1/9

That's the question????

Answer:

10

Step-by-step explanation:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Let [tex](x_1,y_1)[/tex] = (-4, 2)

Let [tex](x_2,y_2)[/tex] = (2, -6)

Substituting given points into the formula:

[tex]\implies d=\sqrt{(2-(-4))^2+(-6-2)^2}[/tex]

[tex]\implies d=\sqrt{(6)^2+(-8)^2}[/tex]

[tex]\implies d=\sqrt{36+64}[/tex]

[tex]\implies d=\sqrt{100}[/tex]

[tex]\implies d=10[/tex]

(a) Since u = cos(x) gives du = -sin(x) dx, we have

∫ sin(x) cos(x) dx = - ∫ (-sin(x)) cos(x) dx

= - ∫ cos(x) d(cos(x))

= - ∫ u du

= - 1/2 u² + C

= -1/2 cos²(x) + C

(b) Now u = sin(x) gives du = cos(x) dx, so

∫ sin(x) cos(x) dx = ∫ sin(x) d(sin(x))

= ∫ u du

= 1/2 u² + C

= 1/2 sin²(x) + C

(c) Since sin(2x) = 2 sin(x) cos(x), we have

∫ sin(x) cos(x) dx = 1/2 ∫ sin(2x) dx

Substitute u = 2x, so that du = 2 dx, and

∫ sin(x) cos(x) dx = 1/2 ∫ sin(2x) dx

= 1/4 ∫ 2 sin(2x) dx

= 1/4 ∫ sin(u) du

= -1/4 cos(u) + C

= -1/4 cos(2x) + C

(d) Integrate by parts, setting

u = sin(x)          ==>  du = cos(x) dx

dv = cos(x) dx  ==>  v = sin(x)

Then

∫ sin(x) cos(x) dx = sin²(x) - ∫ sin(x) cos(x) dx

2 ∫ sin(x) cos(x) dx = sin²(x) + C

∫ sin(x) cos(x) dx = 1/2 sin²(x) + C

The solutions in (b) and (d) are identical, but all 4 are equivalent, and this follows from the identities,

sin²(x) + cos²(x) = 1

cos(2x) = cos²(x) - sin²(x)

Answer:

y-5 = 3/4(x-6)

Step-by-step explanation:

point slope formula is y - y₁ = m(x - x₁) where m=slope and (x₁ ,y₁) is a point on the line.

First find the slope.  From the graph we have pts A and B.

A= (-2,-1) and B is (6,5)

m= y-y₁/x-x₁  m= (5-(-1)/(6-(-2))

m= 6/8 = 3/4

Using point B for x₁ and y₁

y-5 = 3/4(x-6)

The building should be 1.024 meters high and unfortunately there are no buildings with such height in the world.

In this question we must use definition of geometric progression to predict initial height ([tex]h_{o}[/tex]), in meters, in terms of current height ([tex]h[/tex]), in meters, and number of bounces experimented by the ball ([tex]n[/tex]). The expression is described below:

[tex]h = h_{o}\cdot \left(\frac{1}{2} \right)^{n}[/tex]   (1)

If we know that [tex]n = 10[/tex] and [tex]h = 1\,m[/tex], then the initial height is:

[tex]1 = h_{o}\cdot \left(\frac{1}{2} \right)^{10}[/tex]

[tex]h_{o} = 2^{10}[/tex]

[tex]h_{o} = 1024\,m[/tex]

Answer: 5x+7y=500

Step-by-step explanation:

Answer:

First piece = 30m , 2nd is 120 m and third piece is 240 m long.

Step-by-step explanation:

Let the length of the first piece be x m.

Then the length of the second piece = 4x m.

The third piece = 2 * 4x = 8x m.

So x + 4x + 8x = 390

13x = 390

x = 30 m

So 2nd piece = 4*30 and third is 8*30  m.

Hello!

This is an equilateral triangle. In this triangle, the angles are congruent, respectively, the sides. Here, the mediator corresponds to the bisector, the median. So this line will form two  right triangles.

Th 30-60-90

I used the 30-60-90 theorem, which says that the opposing the angle of 30 degrees has the length equal to half the hypotenuse.

Th Pitagora's

Which states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.

Good luck:)
