If the volume of the sphere is 651 m³. Then the diameter of the sphere will be 10.75 meters.

If the given sphere is of radius r units, then its volume is given as:

V = 4/3 πr³ unit³

The volume of the sphere is 651 m³.

Then the diameter of the sphere will be

We know the formula in the form of diameter.

V = 1/6 πd³ unit³

Then we have

651 = 1/6 πd³

πd³ = 3906

 d³ = 1243.31

  d = 10.75 m

Answer:

[tex](a)\ \cos(180 - x)[/tex] --- Never true

[tex](b)\ \cos(90 -x)[/tex] --- Always true

[tex](c)\ \cos(x)[/tex] ---- Sometimes true

[tex](d)\ \cos(2x)[/tex] ---- Sometimes true

Step-by-step explanation:

Given

[tex]\sin(x )[/tex]

Required

Determine if the following expression is always, sometimes of never true

[tex](a)\ \cos(180 - x)[/tex]

Expand using cosine rule

[tex]\cos(180 - x) = \cos(180)\cos(x) + \sin(180)\sin(x)[/tex]

[tex]\cos(180) = -1\ \ \sin(180) =0[/tex]

So, we have:

[tex]\cos(180 - x) = -1*\cos(x) + 0*\sin(x)[/tex]

[tex]\cos(180 - x) = -\cos(x) + 0[/tex]

[tex]\cos(180 - x) = -\cos(x)[/tex]

[tex]-\cos(x) \ne \sin(x)[/tex]

Hence: (a) is never true

[tex](b)\ \cos(90 -x)[/tex]

Expand using cosine rule

[tex]\cos(90 -x) = \cos(90)\cos(x) + \sin(90)\sin(x)[/tex]

[tex]\cos(90) = 0\ \ \sin(90) =1[/tex]

So, we have:

[tex]\cos(90 -x) = 0*\cos(x) + 1*\sin(x)[/tex]

[tex]\cos(90 -x) = 0+ \sin(x)[/tex]

[tex]\cos(90 -x) = \sin(x)[/tex]

Hence: (b) is always true

[tex](c)\ \cos(x)[/tex]

If

[tex]\sin(x) = \cos(x)[/tex]

Then:

[tex]x + x = 90[/tex]

[tex]2x = 90[/tex]

Divide both sides by 2

[tex]x = 45[/tex]

(c) is only true for [tex]x = 45[/tex]

Hence: (c) is sometimes true

[tex](d)\ \cos(2x)[/tex]

If

[tex]\sin(x) = \cos(2x)[/tex]

Then:

[tex]x + 2x = 90[/tex]

[tex]3x = 90[/tex]

Divide both sides by 2

[tex]x = 30[/tex]

(d) is only true for [tex]x = 30[/tex]

Hence: (d) is sometimes true

Answer:

X = 4

Step-by-step explanation:

6x + 8 = 32

6x = 32 - 8

6x = 24

x = 4

the solution is X = 4.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

here, we have,

6x + 8 = 32

6x = 32 - 8

6x = 24

x = 4

hence, the solution is x=4.

Answer:

y = 50x + 40

Step-by-step explanation:

2 points on the graph:

(0, 40) and (2, 140)

Slope:

m=(y2-y1)/(x2-x1)

m=(140 - 40)/(2 - 0)

m=(100)/2

m= 50

Slope-intercept:

y - y1 = m(x - x1)

y - 40 = 50(x - 0)

y - 40 = 50x

y = 50x + 40

Answer:

Arc AB = 8π

Step-by-step explanation:

Length of arc = central angle/360 × 2πr

Where,

Central angle = measure of arc AB = 144° (central angle theorem)

r = radius = 10

Length of arc AB = 144/360 × 2 × π × 10

= 8π

Answer:

14 units

Step-by-step explanation:

Side length of each square is 1 unit.

So, sum of the lengths of all the border edges = 14 units

Thus, the Perimeter of the figure = 14 units

Answer:

-4 and 1

Step-by-step explanation:

-4 times 1 equals -4 and then -4 plus 1 equals 3

The two numbers that satisfy the given conditions are 4 and -1. They multiply to -4 and add up to 3.

To find two numbers that satisfy the given conditions, we can set up a system of equations.

Let's assume the two numbers are represented by 'x' and 'y'. We know that their product is -4 and their sum is 3, so we can write the following equations:

xy = -4 (Equation 1)

x + y = 3 (Equation 2)

To solve this system of equations, we can use the substitution or elimination method. Let's use the substitution method.

From Equation 2, we can express y in terms of x: y = 3 - x.

Substituting this into Equation 1, we get:

x(3 - x) = -4

Expanding and rearranging the equation, we have:

3x - x² = -4

Rearranging again, we get a quadratic equation:

x² - 3x - 4 = 0

We can factor this equation:

(x - 4)(x + 1) = 0

Setting each factor to zero, we find two possible solutions for x:

x - 4 = 0 --> x = 4

x + 1 = 0 --> x = -1

Now, we can substitute these values of x back into Equation 2 to find the corresponding values of y:

For x = 4: y = 3 - 4 = -1

For x = -1: y = 3 - (-1) = 4

Therefore, the two numbers that satisfy the given conditions are 4 and -1. They multiply to -4 and add up to 3.

so, the function is :

y = 5 sin (2x) + 4

Answer:

24.4

Step-by-step explanation:

Given the data :

Month (X) : 0, 1, 2, 4, 6

Weight (Y) : 7.2, 9.4, 10.5, 13.2, 15.9

To obtain the predicted weight at 1 year, we fit the data to obtain the regression model. Using technology, the regression model obtained is :

y = 7.6 + 1.4X1

Substituting x = 1 year into the regression model, we obtained the predicted weight at 1 year ;

1 year = 12 months, hence, x = 12

y = 7.6 + 1.4(12)

y = 7.6 + 16.8

y = 24.4

Answer:

A. P ( Z > 0.54)  = 0,7054

B. P ( Z < 0.54)  =  0.2946

C.1) 1  -  0.2946    =  0.7054

D.1)  1  -  0.2946    =  0.7054

Step-by-step explanation:

A) P ( Z > 0.54)  =  1  -  P (  Z  ≤ 0.54)

P (  Z  ≤ 0.54)  =  0,2946          from  z-table

P ( Z > 0.54)  =  1  - 0,2946

P ( Z > 0.54)  = 0,7054

B) P ( Z < 0.54)  =  0.2946

C)  1 - P ( Z < - 0,54)

     1  -  0.2946    =  0.7054
