Answer:
slope = 5/2
Step-by-step explanation:
(6,36) (10,46)
(46-36)/(10-6)
10/4 = 5/2
It could include all real numbers, really. If you have +$130 you could use them to pay for something. If you have -$27.5 you need to pay this sum to the bank, since you overused your credit.
A right angled triangle can be formed from the given scenario as shown below in the figure:
We have a perpendicular(opposite side), the measure of angle and we are interested in finding the hypotenuse.
sine of the angle relates its perpendicular side to hypotenuse as:
sin(x) = perpendicular/hypotenuse
⇒
Hypotenuse = Perpendicular/sin(x) = 13/sin(70) = 13.8 feet
This means, the length of the ladder is 13.8 feet, rounded to nearest tenth.
Answer:
The input force needed is 225 Newtons
Step-by-step explanation:
From hydraulic pressure laws, we have that the pressure at the same level throughout the body of a fluid is equal.
This means that for the Hydraulic Jack, input pressure = output pressure
Recall,Pressure is a ratio of force and area
i.e pressure = Force / Area
For the hydraulic jack to work properly, the pressure at the input end must be equal to the pressure at the output end.
From this we can compute that the Input force = 225 Newtons
Answer:
The Commutative Properties of Addition and Multiplication ... in an addition expression can be grouped in different ways without changing the sum. ... Mathematicians often use parentheses to indicate which operation should be done ... Rewrite 7 + 2 + 8.5 – 3.5 in two different ways using the associative property of addition.
