2From a point T ,a man moves 12km due west and then moves 12km due south to another point Q. Calculate the bearing of T from Q
How to find the bearing between two points?
Let's assume that:
The point T is the point (0km, 0km).East is the positive x-axisNorth is the positive y-axis.Then, if the man moves 12 km due west and then 12 km due south, the new position is:
( 0km - 12km, 0km - 12km) = (-12 km, -12km)
This lies just in the middle of the third quadrant, so we have 90° per quadrant plus half of that:
90° + 90° + 45° = 225°
This is the angle measured from the positive x-axis, which is the east.
If we consider the negative x-axis, which is the west, the angle would be:
θ = 45°
This means that the bearing is 45° south of west.

AC = 24
Step-by-step explanation:
In a rectangle, the diagonals are the same so AC = BB
3x - 9 = x + 13
3x - x = 13 + 9
2x = 22
x = 11
AC = 3x - 9 = 3(11) - 9 = 33 - 9 = 24

Pattern : 4 is added every time in this table of values.
Step-by-step explanation:
a)
According to the values of the first three terms in the table we can state that:
This is an arithmetic sequence with the first term of 3 and the common difference of 4.We can show this as recursive formula:
a₁ = 3, aₙ = aₙ₋₁ + 4b)
The next terms are:
a₄ = 11 + 4 = 15a₅ = 15 + 4 = 19a₆ = 19 + 4 = 23[tex]6(x-1)-x=-21[/tex]
[tex]\tt Thanks! :)[/tex]
Step-by-step explanation:
Given that:
6(x - 1) - x = -21
Multiply the number outside of the brackets with numbers in the brackets on LHS.
⇛6x - 6 - x = -21
Shift constant from LHS to RHS, changing it's sign.
⇛6x - x = -21 + 6
Subtract the values on LHS and RHS.
⇛5x = -15
Shift the number 5 from LHS to RHS.
⇛x = -15/5
Therefore x = -3

Explain how to determine if the two expressions are equivalent using x = 6 and x = 2. 2x 4 – 1 3 x x.
The two expressions are equivalent.
Linear systemIt is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
2x + 4 - 1 can be represented as 2x + 3
3 + x + x can be represented as 3 + 2x
To findThe two expressions are equivalent.
How do find the two expressions are equivalent?At x = 6
2x + 3 and 3 + 2x
2(6) + 3 and 3 + 2(6)
12 + 3 and 3 + 12
15 and 15
Both are equal.
At x = 2
2x + 3 and 3 + 2x
2(2) + 3 and 3 + 2(2)
4 + 3 and 3 + 4
7 and 7
Both are equal.
Thus the two expressions are equivalent.

https://brainly.com/question/20379472
Answer:
if both expressions have the same value after submitting and simplifying for x = 6 and x = 2, then they are equivalent. Substitute 6 for each variable, 6 for each variable, x, in both expressions. The value on both expressions is 15. Now, substitute 2 for each variable, x, in both expressions. The value of both expressions is 7. Therefore, the expressions are equivalent.

3x - 3 = 15
Find The Value Of x ~
[tex] \: \: \: [/tex]
Answer:
x = 6
Explanation:
3x - 3 = 15
3x = 15 + 3
3x = 18
x = 18 ÷ 3
x = 6
The value of x from the expression is 6
Expression and equationGiven the equation
3x - 3 = 15
Add 3 to both sides
3x - 3 + 3 = 15 + 3
3x = 18
Simplify the result
3x = 18
Divide both sides by 3
3x/3 = 18/3
x = 6
Hence the value of x from the expression is 6

then the halves is further divided in to 2.
then the total becomes 4. then the four pieces are cut into halves, which makes the total of 8 pieces, that is pattern 3..

How far will Tyrique’s robot travel after the wheels have made one full revolution?
Answer:
Distance traveled is equal to the length of wheel circumference as it “unrolls” along the ground as the wheel turns. One full turn of the wheel will move the robot one circumference's distance. Therefore, students will find the distance traveled by multiplying circumference by the number of rotations.
What is the value of f?
Answer: f=78
Step-by-step explanation:
En un cuadrilatero la suma de los angulos internos es 180°
Ademas los angulos alternos internos so iguales.
Por lo tanto el angulo frente a 72° en diagonal tambien es 72°
Si sumamos esos dos angulos obrenemos 144°Si restamos este resultado de 360° obtenemos 360°-144=216 °
Finalmente debemos dividir entre dos los 216°
216/2 = 78°
