Answer:

A dynamic rectangle is a right angled four sided with dynamic symmetry

Answer:

18

Step-by-step explanation:

since U is the midpoint of QT, QT = 2(QU)

similarly, QS = 2 (QR)

because QR is parallel to QS and QU is parallel to QT, triangle QUR is similar to triangle QTS. therefore, the scaling factor between QT/QU and QS/QR is equal to the scaling factor between RU and ST.

therefore,

ST  = 2(RU)

36 = 2(RU)

18 =RU

Answer:

Step-by-step explanation:

If 6:2=8x then answers are A.2x=14 B.2x=48 c. 6x=10 D. 6x=16

6:2=8x can also be written as 6/2 = 8x/1

Cross multiply

2 * 8x = 6*1

16x = 6

Hence the expression can also be written as 16x = 6

Answer:

251.222 feets

Step-by-step explanation:

X = 0.65 rad

To degree ;

X = 37.24°

We need to obtain the height :

Using Sine rule :

(37. 24 + y + 90) = 180

y = 52.76

y / sin Y = D / sin D

200/ sin 52.76 = D / Sin 90

251.22231 = D / sin 90

251.22231 * sin 90 = D

Sin 90 = 1

D = 251.222 feets

Step-by-step explanation:

We have y = 9x - 70 and y = 2x - 32.

=> 9x - 70 = 2x - 32

=> 7x = 38

=> x = 38/7 which is around 5.43.

Answer:

Equations are :--- y = 9x – 70 and y = 2x – 32

Substituting the value of y, we get

[tex]9x - 70 = 2x - 32 \\ 7x = 38 \\ x = \frac{38}{7} \\ \boxed{x = 5.43} \\ y = 9x - 70 \\ y = 9( \frac{38}{7} ) - 70 \\ \boxed{ y = - 21.14}[/tex]

Answer:

A polynomial is an expression, and since mono means 1, monomial has 1 term in the expression, binomial has two, trinomial 3

The answer is:

Work/explanation:

Here's how we classify polynomials based on the number of terms:

monomial - has only one term

binomial - has two terms

trinomial - has three terms

polynomial - has four terms or more

the probability would be

1 in 6, 1/6, or 1:6

Answer:

4x^2 + 7y^3 + 6xy

Step-by-step explanation:

2x^2+2y^3-6xy + 2x^2+5y^3+12xy

2x^2 + 2x^2 = 4x^2

2y^3 + 5y^3 = 7y^3

-6xy + 12xy = 6xy

Step-by-step explanation:

i divide all by 4

=-(5z+6)=-5z-6

Dilation means to increase the size of something.  We can see that the radius of the circle increases by five from circle one to circle two; therefore the rule applied is:

(x, y) -> (x + 5, y + 5)

Answer:

Expression for perimeter of triangle = 5x+8

Step-by-step explanation:

Given that:

Length of bottom of triangle = b = x

Length of other side = a = 3x + 5

Length of last side = c = x + 3

Perimeter of triangle = a + b + c

Perimeter = (3x+5)+x+(x+3)

Perimeter = 3x+5+x+x+3

Perimeter = 5x + 8

Hence,

Expression for perimeter of triangle = 5x+8

Answer:

y = 4x - 6

Step-by-step explanation:

(1, -2) ; Slope (m) = 4

Equation of the line : y - y₁ = m(x - x₁)

y - [-2] = 4(x - 1)

y + 2 = 4x - 4

     y = 4x - 4 - 2

     y = 4x - 6

Answer: 4m

Step-by-step explanation:

20-16= 4

add units

20m - 16 m= 4m

Answer:The instantaneous velocity of the ball after 4 seconds is -0.4 m/s

Step-by-step explanation:

Step-by-step explanation:

If f(x) is the function which represents the distance that a particle moves after x seconds, with velocity v and acceleration a, then

v(x) = f'(x) ⇒ first derivative

a(x) = f"(x) ⇒ second derivative

∵ A ball is thrown vertically from the top of a building

∵ The height of the ball after t seconds can be given by the

  function s(t)= -0.1(t -2)² + 10

- To find the function of the velocity differentiate s(t)

∵ s(t) = -0.1(t - 2)² + 10

- Solve the bracket

∵ (t - 2)² = t² - 4t + 4

∴ s(t) = -0.1(t² - 4t + 4) + 10

- Multiply the bracket by -0.1

∴ s(t) = -0.1t² + 0.4t - 0.4 + 10

- Add the like terms

∴ s(t) = -0.1 t² + 0.4t + 9.6

Now let us differentiate s(t)

∵ s'(t) = -0.1(2)t + 0.4(1)

∴ s'(t) = -0.2t + 0.4

- s'(t) is the function of velocity after time t seconds

∵ s'(t) = v(t)

∴ v(t) = -0.2t + 0.4

We need to find the instantaneous velocity of the ball after 4 seconds

Substitute t by 4

∴ v(4) = -0.2(4) + 0.4

∴ v(4) = -0.8 + 0.4

∴ v(4) = -0.4

∴ The v is -0.4 m/s ⇒ -ve means the velocity is downward

The instantaneous velocity of the ball after 4 seconds is -0.4 m/s

Answer:

44.80

9.27

Step-by-step explanation:

From the data:

Midpoint (x) : __ 25 _ 35 _ 45 _ 55 _ 65

Frequency (f) : _ 1 __ 15 __ 22 _ 8 __ 4

The mean (m):

Σfx / Σf

[(25 * 1) + (35* 15) + (45 * 22) + (55 * 8) + (65 * 4)] / (1 + 15 + 22 + 8 + 4)

= 2240 / 50

= 44.80

Standard deviation :

Sqrt[(Σ(X² * f) / Σf) - m²)]

[(25^2 * 1) + (35^2 * 15) + (45^2 * 22) + (55^2 * 8) + (65^2 * 4)] / (1 + 15 + 22 + 8 + 4)

(104650 / 50) - (44.80²)

1908.51 - 44.80^2

2093 - 2007.04

Sqrt(85.96)

= 9.27

Answer:

Step-by-step explanation:

y = -4/5x + 2

y = 2/3x + 2

2/3x + 2 = -4/5x + 2

10/15x + 12/15x + 2 = 2

22/15x = 0

x = 0

y = 2/3(0) + 2

y = 0 + 2

y = 2

(0, 2)
