Answer:
84 km
Step-by-step explanation:
you times 7 by 4 and get 28 then you times 3 by 28 and get 84 km
The functions y = -4sin (x) and y = 4sin (x) has the given properties.Functions help to define the relationship between the independent and the dependent variable.
<h3>What is function?</h3>
A expressions defining a connection between the independent variable and dependent variable is known as the functions.
A feature that:
The domain is defined as the set of all real numbers.
a single x-intercept
The amplitude is four.
The y-intercept is defined as (0,0)
Because the specified function goes through the functions having "cosine," the functions containing "cosine" can be omitted from the selections (0,0). As a result, we have two options:
Hence y = -4sin (x) and y = 4sin (x) has the given properties.

Please enclose fractions such as 8/7 inside parentheses:
<span>(8/7)x^3+x^4+6x+1
Next, arrange these four terms in order of power of x:
</span>x^4 + (8/7)x^3+ 6x+1 This is the standard form you wanted.
Answer:
B
Step-by-step explanation:
x=-2, f(-2)=-7
x=0, f(0)=5
x=1, f(1)=2
You can use the distance formula for this:
√(x2-x1)²+(y2-y1)²
so you'll get √(1-4)²+(11-7)² = √(-3)²+(4)² = √9+16 = √25 = 5 and 5 is your answer
