Is Plane A Or B Faster

Answers

Answer 1

Answer:

The slope of the graph of plane A is 430, its speed is 430 miles per hour.

The slope of the graph of plane B is 460, its speed is 460 miles per hour.

Plane B is flying faster.

Step-by-step explanation:

The speed of the airplane is the slope of the function, that is, change in distance by change in time. From table, we notice that curve is a first order polynomial, also known that linear function:

Plane A

The slope of the graph of plane A is 430, its speed is 430 miles per hour.

Plane B

The slope of the graph of plane B is:

[tex]v = \frac{1840\,mi-460\,mi}{4\,h-1\,h}[/tex]

[tex]v = 460\,\frac{mi}{h}[/tex]

The slope of the graph of plane B is 460, its speed is 460 miles per hour.

Therefore, plane B is flying faster.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants. An algebraic expression is a combination of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.

The variables represent unknown or unspecified values that can take on different numerical values, while the constants are specific, fixed values that do not change.

The mathematical operations are used to manipulate the variables and constants and to create different algebraic expressions.

Given expression ,

[tex](-3m^5)(–2m^4)[/tex]

we know that [tex]a^m * a ^n = a ^ (m+n)[/tex]

[tex](-3m^5)(-2m^4) = 6m^(5+4)[/tex]

= [tex]6m^9[/tex]

Therefore, the answer is [tex]6m^9[/tex] in standard form.

why the expression -6(5 - k) and 6k - 30 are equivalent.

Answers

Answer:

DB!

Step-by-step explanation:

Because if you multiply them out, they both equal 6k-30.

-6(5-k)=-30+6k, which is equal to 6k-30.

Hope I helped!

because you can use the distributive property with

-6(5-k)

-6×5= -30

-6×-1k= 6k

so that equals 6k-30

What is a Function?

A function is a law that relates two variables namely, a dependent and an independent variable.

A function always has a defined range and domain, domain is all the value a function can have as input and range is all the value that a function can have.

The function is of various types, logarithmic, exponential, quadratic, radical, etc.

The function is shown in the image,

The function is a hyperbolic function, represented by x²/a² -y²/b² = 1 for a hyperbola having a center at the origin.

The function can give any value from the set of real numbers and so,

The range of the function is a set of real numbers.

6. Solve: 143 = 13y​

Answers

Answer:

y=11

Step-by-step explanation:

To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.

To Check your answer:

Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.

Answer:

y=11

Step-by-step explanation:

you have to divide both sides of the equation by the same term and then simplify
