G(3)=(3)+3 - (f(3)=-(3)-5)

Simplify the functions, and use the distributive property.

g(3)=6 - f(3)=3+5

Continue to simplify:

g(3)=6 - f(3)=8

g(3)-f(3)=6-8

g(3)-f(3)=-2

How to do this question plz answer me ​
alexandr402 [8]

Answer:

140

Step-by-step explanation:

We first find out how much degrees altogether in the pentagon so we do

S = (n-2) x 180

s is the sum in the shape

n is the number of sides

S = (5-2) x 180

S = 3 x 180

S =540

Now that we have the sum we can add all the sides, first lets make the side ABC = x and side BCD = 2x:

115 + 125 + 90 + x + 2x = 540

330 + 3x = 540

3x = 540 - 330

3x = 210

x = 70

Now that we know x = 70 we can find side BCD, it says its is 2 x angle ABC

so we do 2x70 = 140

so Angle BCD = 140

I hope i did this correctly.

A cylindrical container of three rubber balls has a height of 27 centimeters and a diameter of 9 centimeters. Each ball in the c
e-lub [12.9K]

Answer:

Volume of space in cylinder = 572.27 cm³ (Approx.)

Step-by-step explanation:

Given:

Height of cylinder = 27 cm

Diameter of cylinder = 9 cm

Radius of cylinder = 9 / 2 = 4.5 cm

Number of sphere ball = 3

Radius of sphere ball = 4.5 cm

Find:

Volume of space in cylinder

Computation:

Volume of space in cylinder = Volume of cylinder - Volume of 3ball

Volume of space in cylinder = πr²h - 3[(4/3)πr³]

Volume of space in cylinder = [22/7][4.5]²[27] - 3[(4/3)[22/7][4.5]³]

Volume of space in cylinder = [(3.14)(20.25)(27)] - [(4)(3.14)(91.125)]

Volume of space in cylinder = 1,716.795 - 1,144.53

Volume of space in cylinder = 572.265

Volume of space in cylinder = 572.27 cm³ (Approx.)

How to mathematically divide a circle into 60 parts with coordinates?
Naddika [18.5K]
The coordinates are (rcos(6n),rsin(6n)) where r is the radius of the circle and n ranges from 0 to 59.
60 parts gives the angle 360/60=6 degrees, so multiples of this angle (6n) determine the coordinates.
When n=0, the coords are (r,0); when n=5, the coords are (r√3/2,r/2); when n=10 the coords are (r/2,r√3/2), etc.

The slope intercept form​
harina [27]

Answer:Slope-intercept form is y = mx + b form, where m represents the slope, and b represents the y-intercept. So if the equation of a line is y = 3/4 x - 2, then the line is written in slope intercept form, or y = mx + b form, with m = 3/4 and b = -2.
