based on the values in the table, what is the smallest number of instances at which the acceleration of the plane could equal zero on the open interval 0 < c < 6?
The smallest number of instances at which the acceleration of the plane could equal zero on the open interval 0 < c < 6 is t= 25 to t= 30.
By the mean value theorem, somewhere between t = 0 and t = 15 , v'(t) = 0, because v(15)-v(0)/15-0 = 0. Also somewhere between t=25 and t=30, v'(t) = 0, because v(30) - v(25) / 30 - 25 = 0. This means a(t) = 0 for at least two values of t.
f(t) = 6+cos(t/10)+3sin(7t/40)
a(t) = f'(t) = 1/10 sin (t/10) + 21/40 cos (7t/40)
f'(23) = -.408 miles/min²
Average Velocity = 5.916 miles per minute
Average Speed is characterized as the adjustment of position or displacement of the object (∆x) partitioned when the time interval (∆t) in which the displacement happens. The average speed can be a positive or negative sign on the indication of the displacement of the object.

1/4=[tex]2^{x}[/tex] find x
Answer:
x = 1/8
Step-by-step explanation:
divide the two from both both sides
1/4 = 2x
(1/4)/2 = x/2
1/8 = x
Answer: x = -2
Step-by-step explanation:
X is -2 because whenever you get a negative exponent you gotta make it into a fraction which is [tex]\frac{1}{4}[/tex] because I ignored the negative sign for a second and did it normally so 2 to the power of 2 is 4 put it as a fraction 1 over 4.

The correct option (4)
A function is defined as a relationship between a collection of inputs with one output each. In simple terms, a function is a relationship between inputs, with each input corresponding to exactly one output. Every function has a domain and a codomain or range. A function is commonly denoted by f(x), where x is the input.
From the given information, we have that
f(x) = 3x - 4 and
g(x) = f(2x)
Then,
g(x) = f(2x) becomes
g(x) = f(2x) = 3(2x) -4
g(x) = 6x - 4
Now, we'll plug x numbers ranging from 1 to 3 into the equation.
When x = 1
g(x) = 6x - 4 becomes
g(x) = 6(1) - 4
g(x) = 6 - 4
g(x) = 2
When x = 2
g(x) = 6x - 4 becomes
g(x) = 6(2) - 4
g(x) = 12 - 4
g(x) = 8
When x = 3
g(x) = 6x - 4 becomes
g(x) = 6(3) - 4
g(x) = 18 - 4
g(x) = 14
Hence, the table that represents g(x) is
x g(x)

What is a word problem in mathematics?A word problem consists of describing a situation as well as providing the necessary information to a question verbally that is to be solved by by calculations mathematically.
The initial number of marbles Brea had = 10
The number of marbles Brea had at the end = 0
Let A represent the number of marbles given to Abby, let B represent the number of marbles given to Brea and let C represent the number of marbles given to Cleo, we get;
The number of marbles Abby gave Brea and Cleo = B + C
The number of marbles Brea gave Abby and Cleo = (A - (B + C)) + 2·C

Which one is the function here and why
The fourth option D is a function of the form of f(x) = ax(x-2)(x+2) where a is a constant.
We know that any function of the form y = f(x) will pass through the x axis at points such that there is only 1 value of x for a value of y.
Of all the options given the option D is in the form of polynomial expression which crosses the x-axis at points (-2,0 ) , (0,0) and (0,2).
The graph of the function at D will be of the form:
f(x) = ax(x-2)(x+2) a is a constant.
At y = 0 , x =-2 ,0 and 2.
Therefore for one value of y there are 3 values of x. but every value of x is mapped into one single value of y only.
For option A at x = 2 , y ahs two values -2 and 2 so it is not a function of x.
For option B the graph is not differentiable at certain points, hence it is not a function.
For option C again y has 2 values for a single x.
The values of x are used to denote the roots and zeros of the expression, which are also on the left side of the equation, and to satisfy the equation. A quadratic problem should only have two possible solutions. One contends that if there is just one solution, the problem has numerous causes.

Step-by-step explanation:
You want the real roots of the quadratic x^2 + 5x = 6.
FactorizationThe roots are easily identified from the factored form of the equation. The factors will involve the constants that have a sum of +5 and a product of -6.
-6 = 6·(-1) = 3·(-2)
Sums of the factor pairs are 5 and 1. We will use the constants that have a sum of 5.

x^2 +5x -6 = 0 . . . . . standard form
(x +6)(x -1) = 0 . . . . . . . factored form
Zero product ruleThe zero product rule tells us that a product will be zero if and only if at least one of the factors is zero. To find the values of x, we set the factors equal to zero and solve for x.
(x +6) = 0 ⇒ x = -6
(x -1) = 0 ⇒ x = 1

In mathematics, an equation is a method that expresses the equality of two expressions, by using connecting them with the equals signal =. The phrase equation and its cognates in other languages may also have subtly exclusive meanings; for example, in French, an equation is described as containing one or more variables, at the same time as in English, any nicely shaped formula together with expressions associated with an equal’s signal is an equation.
Solving an equation containing variables includes determining which values of the variables make the equality actual. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that satisfy the equality are referred to as solutions of the equation. Equations come in two varieties: identities and conditional equations. An identification is actual for all values of the variables. A conditional equation is handiest genuine for unique values of the variables.
