Answer:

Step-by-step explanation:

using pythagoras theorem

a^2 + b^2 = c^2

4^2 + y^2 = 21^2

16 + y^2 = 441

y^2 = 441 - 16

y^2 = 425

[tex]y = \sqrt{425}[/tex]

[tex]y = 5\sqrt{17}[/tex]

y = 13.2

a^2 + b^2 = c^2

4^2 + x^2 = 7^2

16 + x^2 = 49

x^2 = 40 - 16

x^2 = 33

x = [tex]\sqrt{33}[/tex]

x = 5.7 m

This may be incorrect, so sorry if it is! The answer I got is 2760y.

The density of golf ball is 0.000113 gm/mm³

What is volume ?

Volume is a three dimensional space occupy by the body of particular shape such as here :

volume (V) of sphere with radius r : 4πr³/3

it is given that :

golf ball has a diameter d of = 42.67 millimeters

r = d/2 = 21.33 mm

golf ball has a mass m of = 45.93 grams

First, let us find the volume of the golf ball can be determined using the formula:

V = 4πr³/3

Substituting r = 21.33mm, we get;

V = 4π(21.33)³/3

V = 40650 mm³

Now, to find the number of grams per cubic millimeter of the material used to make the golf ball we find the density of golf ball :

ρ = m/V

ρ = 45.93/40650

ρ = 0.000113 gm/mm³

Therefore, the density of golf ball is 0.000113 gm/mm³

Answer:

9 and 10

Step-by-step explanation:

To work this out, you can either evaluate [tex]\sqrt{89}[/tex] or find the 2 closest perfect squares to 89.

With the second method, the 2 closest perfect squares are 81 and 100, otherwise known as 9² and 10². This means [tex]\sqrt{81}[/tex] is between 9 and 10.

With the first method, the result is 9.4339811320... which is between 9 and 10.

Answer:

y=2

Step-by-step explanation:

3 = (y+7)/3

Multiply each side by 3

3*3 = (y+7)/3 *3

3*3 = y+7

9 = y+7

Subtract 7 from each side

9-7 = y+7-7

2 =y

Answer:

2 = y

Step-by-step explanation:

3 = y + 7 ÷ 3

multiply both side of equation by 3

3 × 3 = y + 7 ÷ 3 / 3

9 = y + 7

subtract 7 from both side

9 - 7 = y + 7 - 7

2 = y

Answer:

224

Step-by-step explanation:

Hello!

To find f(-7) you simply plug the value, -7, into the function.

This will get you:

f(-7) = 4(-7)^2 - 4(-7)

Remember that the square of a negative number is a positive! Also, remember to use the order of operations (PEMDAS)!

This will get you:

f(-7) = 4(49) - 4(-7)

f(-7) = 196 - (-28)

f(-7) = 224

Hope this helps!

Answer:

The answer is Yes .. Ron is correct

Step-by-step explanation:

This is because each side of the outer square is 2 units summing up to 8 units. So dividing each into two equal parts give 1 unit each.

Each side of the inner square divides the outer square into two making each side 1 unit.

The inner square thus takes 1 unit for it's side summing the perimeter to 4 units.

[tex] \large \boxed{ {a}^{2} + {b}^{2} = {(a + b)}^{2} - 2ab}[/tex]

The formula is derived from the (a+b)² which can be expanded as:

[tex] \large \boxed{ {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} }[/tex]

Now since we only want a²+b² and not 2ab. We can add -2ab after (a+b)² which result in (a+b)²-2ab. This formula is pretty useful it comes to higher maths.

(x +4)^2 + (y-7)^2 = 36

Step-by-step explanation:

The equation of a circle is of the form

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x- -4)^2 + (y-7)^2 = 6^2

(x +4)^2 + (y-7)^2 = 36

Answer:

C, which is 340!

Step-by-step explanation:

Split the polygon into two rectangles to make it easier (see the attachment below), and calculate the areas of both rectangles. Then add the areas of the two rectangles, 264+76=340. So the answer is 340 square units, or C. Hope this helped!! :)

The area of polygon = 340 square units.

Area of rectangle = Length [tex]\times[/tex] [tex]\tmes[/tex]breadth

Area of rectangle (side A) = 19 [tex]\times[/tex] 4 = 76

Area of rectangle (Side B) = 24 [tex]\times[/tex] 14 = 264

To estimate the area of the polygon, add both of the equations then we get

Area of the polygon

= Area of a rectangle (side A) + Area of a rectangle (Side B)

= 76 + 264

Area of the polygon  = 340 square units.

Therefore, the correct answer is option C. 340 square units.

Step-by-step explanation:

Answer:

gradient = - [tex]\frac{3}{4}[/tex] , y- intercept = [tex]\frac{5}{4}[/tex]

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 )

Given

3x + 4y = 5 ( subtract 3x from both sides )

4y = - 3x + 5 ( divide terms by 4 )

y = - [tex]\frac{3}{4}[/tex] x + [tex]\frac{5}{4}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{3}{4}[/tex] and y- intercept c = [tex]\frac{5}{4}[/tex]
