An equation is also called a number sentence. Explain how an equation in mathematics is like a sentence in English.

 A number sentence is a mathematical sentence, made up of numbers and signs.The expressions given in  examples indicate equality or inequality.A number sentence can use any of the mathematical operations from addition, subtraction, multiplication to division. Symbols used in any number sentence vary depending upon what they indicate.Number sentences can be true or they may not be true.

For example:

10 + 5 = 15. Here we are using the = sign which indicates a balance of both sides.

However, there could also be number sentences which say:

12 + 6 = 9 is not true, but 12 + 6 = 18 is true.

Therefore, a number sentence does not necessarily have to be true. However, every number sentence gives us information, and based on the information provided; it is possible to change the statement from false to true.

So, a number sentence contains numbers, mathematical operations, equal to or inequality sign and a number after the equality or inequality sign. If we remove any of these components, it will no longer be a number sentence.

Step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
