Answer:

The value of V is  double of Q is

D)  V = 2Q

Step-by-step explanation:

A)

  The value of V is the square of Q

        V = Q²

B)

The value of V is the addition '2' of Q

       V = Q+2

C)

The value of V is the divided 'Q' by'2'

  V = Q/2

D)

The value of V is  double of Q is in notation

V = 2Q

Step-by-step explanation:

Answer:

10,

Step-by-step explanation:

The bottom right angle is 45 degrees so the top left must also be 45 degrees (180 - 45 - 90 = 45). This means that x is the same as the left side: 10.

The triangle is right angled so we can use pythagoras on it: x^2 + 10^2 = y^2 = 200

y = √200 = √100√2=10√2

Answer: B: diameter

Step-by-step explanation:

The blue line the goes across the shape is called the diameter

Answer: umm I think the circumference

Answer:

89/160

Step-by-step explanation:

Total number of students= 320

Total number of students=x+y=320

Let x= number of boys

Let y= number of girls

If there are 36 more boys than girls:

36+y=x

x+y=320 ( given x= 36+y)

36+y+y=320

36+2y=320

2y=320-36

2y=284

y=284/2

y=142

Therefore number of girls=142

Since 36+y=x

36+142=x

x=178

Therefore number of boys =178

Fraction of students that are boys=

178/320

89/160

Answer:

The value of n is 10

Step-by-step explanation:

The formula of the nth term of the arithmetic progression is a[tex]_{n}[/tex] = a + (n - 1)d

The formula of the sum of nth terms is S[tex]_{n}[/tex] = [tex]\frac{n}{2}[/tex] [2a + (n - 1)d]

∵ An AP has a common difference of 3

∴ d = 3

∵ The nth term is 32

∴ a[tex]_{n}[/tex] = 32

→ Substitute them in the 1st rule above

∵ 32 = a + (n - 1)3

∴ 32 = a + 3(n) - 3(1)

∴ 32 = a + 3n - 3

→ Add 3 to both sides

∴ 35 = a + 3n

→ Switch the two sides

∴ a + 3n = 35

→ Subtract 3n from both sides

∴ a = 35 - 3n ⇒ (1)

∵ The sum of the first n terms is 185

∴ S[tex]_{n}[/tex] = 185

→ Substitute the value of S[tex]_{n}[/tex] and d in the 2nd rule above

∵ 185 = [tex]\frac{n}{2}[/tex] [ 2a + (n - 1)3]

∴ 185 = [tex]\frac{n}{2}[/tex] [2a + 3(n) - 3(1)]

∴ 185 = [tex]\frac{n}{2}[/tex] [2a + 3n - 3]

→ Multiply both sides by 2

∴ 370 = n(2a + 3n - 3)

∴ 370 = 2an + 3n² - 3n

→ Substitute a by equation (1)

∴ 370 = 2n(35 - 3n) + 3n² - 3n

∴ 370 = 70n - 6n²+ 3n² - 3n

→ Add the like terms in the right side

∵ 370 = -3n² + 67n

→ Add 3n² to both sides

∴ 3n² + 370 = 67n

→ Subtract 67 from both sides

∴ 3n² - 67n + 370 = 0

→ Use your calculator to find n

∴ n = 10 and n = 37/3

∵ n must be a positive integer ⇒ 37/3 neglecting

∴ n = 10

∴ The value of n is 10

Answer:

x = 21

Step-by-step explanation:

2x and 42 are alternate angles and are congruent, so

2x = 42 ( divide both sides by 2 )

x = 21

Answer:

1/12

Step-by-step explanation:

Probability is a ratio derived as the number of possible outcomes divided by the total outcome.

On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)

= 3/6

The probability of rolling a 4  P(4)

= 1/6 (4 appears on one side)

Hence  the probability of rolling an even on the first roll and a four on the second roll

P(En4) = 3/6 * 1/6

= 3/36

= 1/12

Answer:

5

Step-by-step explanation:

In a 30  60 90 triangle the shortest side is considered to be half the hypotenuse. So in this case, 10 is the hypotenuse and 10/2 = 5.

Answer:

23

Step-by-step explanation:

The sum of any two sides of a triangle has to be greater than the other side

Only 23 meets this criteria

Answer:

i think it is 23

Answer:

1/2

Step-by-step explanation:

Let the coordinate points be (6,3) and (4,2)

Slope = y2-y1/x2-x1

x1 = 6, y1 = 3, x2 = 4 and y2 =2

Substitute

slope = 2-3/4-6

Slope = -1/-2

Slope = 1/2

Hence the slope of the coordinate is 1/2

Note that the other Coordinate was assumed

Answer: 65.8

Step-by-step explanation:

First multiply 10 x 2=20

then you add 82 and 3.8 which is 85.8

then you subtract 20 from 85.8 and you get 65.8

Complete Question

The displacement (in centimetres) of a particle moving back and forth along a straight line is given by the equation of motion

s = 4 sin(πt) + 2 cos(πt),

where t is measured in seconds. (Round your answers to two decimal places.)

(a) Find the average velocity during each time period.

i. [1,2]

ii. [1 ,1.1]

iii. [1, 1.01]

Answer:

[tex]V_A_1=4m/s[/tex]

[tex]V_A_2=-11.38m/s[/tex]

[tex]V_A_3=-12.47m/s[/tex]

Step-by-step explanation:

From the question we are told that

Equation of motion is given by

[tex]s = 4 sin(\pi t) + 2 cos(\pi t)[/tex]

Generally equation for average velocity is mathematically given by

  [tex]V_A=\frac{S(y)-S(x)}{y-x}[/tex]

  [tex]V_A=\frac{4 sin(\pi t) + 2 cos(\pi t)(y)-(4 sin(\pi t) + 2 cos(\pi t))(x)}{y-x}[/tex]

a) Co-ordinate(1,2)

 [tex]V_A=\frac{4 sin(\pi y) + 2 cos(\pi y)-(4 sin(\pi x) + 2 cos(\pi x))}{y-x}[/tex]

 [tex]V_A=\frac{4 sin(\pi 2) + 2 cos(\pi 2)-(4 sin(\pi) + 2 cos(\pi))}{2-1}[/tex]

 [tex]V_A=\frac{0+ 2*1-(0 + 2)*-1}{2-1}[/tex]

 [tex]V_A_1=4m/s[/tex]

b)Co-ordinate(1,1.1)

    [tex]V_A_2=\frac{4 sin(\pi 1.1) + 2 cos(\pi 1.1)-( sin(\pi ) + 2 cos(\pi ))}{1.1-1}[/tex]

    [tex]V_A_2=\frac{0+ 2*-1-(-0.30902*2)+2*-0.95106}{1.1-1}[/tex]

    [tex]V_A_2=\frac{((-0.30902*2)+2*-0.95106)-(0+ 2*-1)}{1.1-1}[/tex]

    [tex]V_A_2=\frac{((-3.1382)-(-2)}{1.1-1}[/tex]

    [tex]V_A_2=-11.38m/s[/tex]

c) Co-ordinate(1,1.01)

    [tex]V_A_3=\frac{4 sin(\pi 1.01) + 2 cos(\pi 1.01)-( sin(\pi ) + 2 cos(\pi)}{1.01-1}[/tex]

    [tex]V_A_3=\frac{0.2214045768+1.996933901)-(-2)}{1.01-1}[/tex]

    [tex]V_A_3=\frac{(-2.12)-(-2)}{1.01-1}[/tex]

    [tex]V_A_3=-12.47m/s[/tex]

Answer:

4.5 years ; (3.25, 4.75)

Step-by-step explanation:

Given that :

Mean , m = 4

Standard deviation, s = 0.75

The upper quartile, which is the 3rd quartile of a standard normal distribution is 0.67

Therefore, the upper quartile Q3:

Q3 = mean + 0.67 * standard deviation

Q3 = 4 + 0.67(0.75)

Q3 = 4 + 0.5025

Q3 = 4.5025

Q3 = 4.5 years

Range of values that contain the middle 68%

According to the empirical rule;

68% is within 1 standard deviation of the mean

Therefore ;

Interval will be ;

Mean ± 1 standard deviation

(4 - 0.75) ; (4 + 0.75)

(3.25, 4.75)

Answer:

x = 30°

Step-by-step explanation:

Since 2 of the sides are congruent then the triangle is isosceles and the 2 base angles are congruent, both 75°

The sum of the 3 angles in a triangle = 180°, then

x = 180° - (75 + 75)° = 180° - 150° = 30°
