Answer:
w = 21
x = 13
y = -11
z = -16
Step-by-step explanation:
Matrix subtraction is simply subtracting "corresponding" values e.g. row 1 column 1 value of one matrix and row 1 column 1 value of another matrix, and so on...
Thus, w = 17 - (-4) = 17 + 4 = 21
x = 12 - (-1) = 12 + 1 = 13
y = -3 -8 = -11
z = -2 -14 = -16
These are the values of w, x, y and z , respectively.
this triangle has 3 sides one is 12, lets call this side a²
another side is 72, lets call this side c²
this triangle must follow Pythagoras therom if it is right angled, that is a²+b²=c²
where a and b are the two shorter sides and c is the longest side (called the hypotenuse) opposite the right angle
to find the last side you do 72² - 12² = 5040
but it is the square root of 5040 which is 70.99 (two decimal places) if you want it in decimal form, if you want it in surd form it is √5040
According to math, I divided 3 by 1/4 and got 12
Answer:
Step-by-step explanation:
we know that
The perimeter of the hexagon is equal to
Remember that
----> is the length base of an isosceles triangle
so
The perimeter is equal to
Find the length side BC
Let
x ----> the measure of the vertex angle in the isosceles triangle
The measure of the vertex angle in the isosceles triangle is equal to
Applying trigonometric property
In the right triangle of the attached figure
----> by CAH (adjacent side divided buy the hypotenuse
Remember that
substitute
Find the perimeter
The speed of the bus is 125 kmph
Speed is a scalar quantity that refers to how fast an object is moving.
Given that, a speed of a bus that travels 250 km in 2 hours.
We know,
Speed = distance / time
Distance = 250 km
Time = 2 hours
Speed = 250 / 2
= 125 kmph
Hence, the speed of the bus is 125 kmph
