Answer:

4 > x > -7

Step-by-step explanation:

4 > x > -7

Because we usually put lower numbers to the left on a number line

the convention is to present this as

-7 < x < 4

What is the length of the edge of a cube with a wolume of 512?

il63 [147K]

A≈8
V Volume

Using the formula
V=a3
Solving fora
a=V⅓=512⅓≈8

Therefore, to find the lenght of an edge of the cube, just find the cube root of the volume. In this case, the cube root of 512 is equal to 8.

Trigonometry: 1) Work out the bearing from B to C. 2) Calculate the bearing of D from B

kakasveta [241]

Answer:

see below

Step-by-step explanation:

a bearing is the angle in degrees measured clockwise from north.

Triangle ABC is a right triangle

Tan C = opp side / hyp

tan C = AB / CA

tan C = 30/30

tan C = 1

taking the inverse tan

tan ^ -1 tan C = tan ^ -1 ( 1)

C = 45 degrees

This is 90+45 degrees from North

135 degrees from north

Tan B = opp side / hyp

tan B = AD/BA

tan B = 45/30

tan B = 3/2

taking the inverse tan

tan ^ -1 tan B = tan ^ -1 ( 3/2)

D = 56.30993247

Add 180 degrees

180+56.30993247

236.3099325 from north

Answer:

Theory: g is the parent, y is the child, and x is the supporting number in the formula's syntax.

Step-by-step explanation:

-4(x a number) - 6 = -5(y a number) + 2.

basically g(x) is g times x equals y, which is the supporting factor in this equation.

hope this helps if not I can try to make it right!

In triangle ABC, c = 8, b = 6, and ∠C = 60°. sin∠B = _____

guajiro [1.7K]

Answer:
sin B = 0.65

Explanation:
To solve this question, we will need to use the sine law that is shown in the attached image.

Here, we have:
c = 8
b = 6
angle C = 60°

Therefore:
 $\frac{b}{sin(B)}$ = $\frac{c}{sin(C)}$

$\frac{6}{sin(B)}$ = $\frac{8}{sin(60)}$

sin B = 0.649 which is approximately 0.65

Hope this helps :)
