6 0

Step-by-step explanation:

v=70km/h

t=7 seconds

u=0

first change the unit km/h to m/s

1000km=1m

3600seconds=1h

v=70km/h ×1000km/3600s

v=19.44m/s

acceleration =final velocity(v)-initial velocity(u)/time

acceleration=19.44m/s-0m/s=19.44m/s

19.44/7=2.78 m/s

Use the triangle below and the given trigonometric ratio to determine which angle in the triangle below is
4vir4ik [10]
Cosine is the ratio of the adjacent side to the hypotenuse.

In short, we have this equation
cos(angle) = adjacent/hypotenuse

In the case of cos(A) = 18/19.5 we can see that
adjacent = 18
hypotenuse = 19.5

The side of 18 cm is next to angle 2, so the 18 cm side is adjacent to angle 2 (in contrast, the 7.5 cm side is the opposite leg in relation to angle 2)

So that's why the answer is angle 2
In other words, replace the '2' angle marker with 'A' to be able to write cos(A) = 18/19.5

Answer:

1  :

Step  2  :

Equations which are never true :

2.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    2x+1 = 0

Subtract  1  from both sides of the equation :

                     2x = -1

Divide both sides of the equation by 2:

                    x = -1/2 = -0.500

One solution was found :

                  x = -1/2 = -0.500
