Answer:
x=1
Step-by-step explanation:
2x-17x+15=0
Combine like terms
-15x +15 = 0
Add 15x to each side
-15x+15x+15=0+15x
15 = 15x
Divide by 15
15/15 = 15x/15
1 =x
Answer:
x=1
Step-by-step explanation:
x=1 because you need to isolate the variable by dividing each side factors that don't have a variable.
Hello!
Answer:
Step-by-step explanation:
→ We want the value of n - n - p when n = -9 and p = -4.
→ Let's replace n by -9 and p by -4 in the expression:
→ Simplify the expression:
Conclusion:
If n = -9 and p = -4 in the expression n - n - p, this expression is equal to 4.
Fx, Fy = F cos θ, F sin θ
This is a fundamental problem with vector components.
The list below shows some recognized methods to represent a vector. i.e., a force.
It is possible to split one vector into two vectors. This process is called resolving and the vectors that we get are called the components of the original vector.
Vector problems can always be solved by using the mathematics of trigonometry, i.e., the functions of sine or cosine. This is particularly appropriate when resolving.
By using the cartesian coordinate system, see the attachment on how to calculate the values of either these components.
Here, the angle between the vector F and the horizontal axis we call θ (theta).
As a reminder:
Keywords: express Fx and Fy, in terms of the length of the vector F, and the angle θ, with the components, separated by a comma, resolving, split, horizontal, vertical, angle, theta, sine, cosine, trigonometry, cartesian coordinate system
The components of the vector F are and .
Further Explanation:
A physical quantity can be defined as the physical property that can be measured and have some value in numbers.
For example- mass, amount of substance, length, time, electric current, temperature, force, light intensity, density, velocity, speed etc.
A quantity is said as a vector if it has some magnitude and direction in order to give the details regarding the quantity.
For example- Force, velocity, current density, electric field, magnetic field, displacement, acceleration, momentum etc.
A quantity is said as a scalar if it has only the magnitude in order to give the details regarding the quantity.
For example- speed, distance, current, volume, density, mass, energy, time, temperature etc.
Given:
The resultant vector is .
The horizontal component is .
The vertical component is .
Concept:
Let a vector have some length and making an angle with horizontal axis.
The triangle rule of resultant vector state that when two vector is denoted by the two sides of the triangle and the magnitude and the direction is taken in the same direction then the third side of the triangle denoted by resultant vector with some magnitude and direction.
The diagram is drawn as shown in the Figure 1.
The vertical component is along y-axis and the vertical component of the vector is expressed as:
The horizontal component is along x-axis and the horizontal component of the vector is expressed as:
therefore, the components of the vector F are and .

The probability that he chooses trees of two different types is 0.6 or 60%.
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a landscaper who is selecting two trees to plant.
The total number of trees he has = 5
Total ways of choosing the two trees =
= 10
Total ways of choosing one of each =
= 6
So probability:
=
= 0.6 or 60%
Thus, the probability that he chooses trees of two different types is 0.6 or 60%.
