20. Let g be a twice-differentiable, increasing function of t. If g(0) 20 and g(10) 220, which of the following must be true on the interval 0 < 10 ? (A) g'(t) 0 for some t in the interval. (B) g) 20 for some t in the interval. (C) g"(t) 0 for some t in the interval. (D) g"(t) > 0 for all t in the interval
For given function the correct solution is g'(t) = 20 for some t in the interval.
A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
For a given function, y = F(x), if the value of y is increasing on increasing the value of x, then the function is known as an increasing function and if the value of y is decreasing on increasing the value of x, then the function is known as a decreasing function.
Given that g(10)= 220
g(0)= 20
So putting values in condition of differentiation for increasing function we get:
[tex]\frac{g(10)-g(0)}{10-0}[/tex]
= [tex]\frac{220-20}{10}[/tex]
=20
Hence as we can see that the correct solution for given function is g'(t) = 20 .

Which types of transformations change the shape of a graph?
Dilation
By maintaining the object's orientation or shape, this type of translation either expands or contracts the object. This is referred to as resizing.
What is Graph Transformation?
A graph can be transformed to produce a different version of the one that came before it. The x-y plane can be used to translate or shift the graphs. In addition to these modifications, they may also be stretched.
Types of Stretching of Graphs
Stretching out VerticallyConsider the case where we need to lengthen a graph by a factor of 2. Next, change the y value. Now, each point of the function F's form (x, y) shifts to the point (x, 2y)*
Stretching out horizontallyAdjust the x value if a graph needs to be stretched horizontally by a factor of two. The point (2x, y) in function F is now the new location for all points with the form (x, y) in function F.
Types of Translation in Graphs
Moving HorizontallyA graph is horizontally translated by moving the base graph to the left or right in relation to the x-axis. Consider that if we want to move a graph horizontally by 1 unit, we would also need to change the x value.
Moving VerticallyA graph's base graph is moved up or down in the y-axis direction when it is vertically translated. Each point on a graph is moved b units vertically to translate the graph in that many directions.

What is the slope of 4x Y =- 1?
The slope of 4x - Y = -1 is 4.
We know that the general form of the equation of a straight line is:
y = mx + c,

For what values of k the roots of the equation x² 4x?
The equation x² + 4x = 0 has no real roots for any value of k.
The equation x² + 4x = 0 can be solved by using the Quadratic Formula. We can rearrange the equation to be in the form of ax² + bx + c = 0. In this case, a = 1, b = 4 and c = 0. We can then plug these values into the Quadratic Formula to find the roots of the equation.
The Quadratic Formula is x = [-b ± √(b² - 4ac)] / 2a
Plugging in our values of a, b, and c we get: x = [-4 ± √(-4² - 4(1)(0))] / 2(1)
Simplifying this equation we get: x = [-4 ± 0] / 2
The equation simplifies to: x = [-4 / 2] and x = [0 / 2].
Since both of these roots are imaginary, the equation x² + 4x = 0 has no real roots for any value of k.

if mary had 23 apples and she give 10 to her fren. how many apples do she have left?
Franklin National Life Insurance Company purchased new computers for $300,000. If the rate at which the computers' resale value changes is given by the function V'(t) = 5700(t − 10) where t is the length of time since the purchase date and V'(t) is measured in dollars per year, find an expression V(t) that gives the resale value of the computers after t years. V(t) = dollars How much would the computers sell for after 5 years? (Round your answer to the nearest dollar.) $
To find an expression for V(t), we can integrate V'(t) with respect to t. Doing so, we have:
V(t) = ∫V'(t) dt = ∫5700(t − 10) dt = 5700 ∫(t − 10) dt = 5700 [t^2/2 - 10t] + C
Since V(t) is the resale value of the computers, the constant of integration C should be the initial value of V(t), which is the cost of the computers. Therefore, we have:
V(t) = 5700 [t^2/2 - 10t] + 300000
Now, to find the value of the computers after 5 years, we can substitute t = 5 into the expression for V(t):
V(5) = 5700 [5^2/2 - 10*5] + 300000 = 5700 [25/2 - 50] + 300000 = 5700 [-12.5] + 300000 = -67500 + 300000 = 232500
Thus, the computers would sell for approximately $232,500 after 5 years.
Explanation: The function V'(t) gives the rate at which the resale value of the computers changes with time. In other words, it gives the slope of the function V(t) at any point in time. To find the function V(t) itself, we need to integrate V'(t) with respect to t. The constant of integration C is added to the result of the integration to ensure that the initial value of V(t) is equal to the cost of the computers. Once we have the expression for V(t), we can find the value of the computers at any point in time by substituting the appropriate value for t into the expression. In this case, we found that the value of the computers after 5 years is approximately $232,500.

How do you find the vertical and horizontal asymptotes of a function?
The vertical asymptotes can be simply found by equating the denominator of a function to zero and solving for x, but the vertical asymptotes requires consideration of the highest degrees of x in numerator and denominator.
What is veritcal asymptote?A vertical asymptote is a vertical line that guides the graph of the function but is not part of it. Because it appears at an x-value outside of the function's scope, the graph can never cross it. There may be several vertical asymptotes for a given function.
What is horizontal asymptote?A graph's horizontal asymptote is a horizontal line with the equation y = b, where the graph moves closer to the line as the inputs go closer to 0 or -1.
Find the x values where the function is undef for the purpose of determining a function's vertical asymptotes. Consider the degree of the numerator and the degree of the denominator while looking for a function's horizontal asymptotes. The horizontal asymptote is y = 0 if the degree of the numerator is smaller than the degree of the denominator. There is no horizontal asymptote if the degree of the numerator is higher than the degree of the denominator. The horizontal asymptote is y = the coefficient of the highest-degree term in the numerator divided by the coefficient of the highest-degree term in the denominator if the degree of the numerator and denominator are equal.

Let the two numbers be x and y. Let the larger number be x and the smaller number be y.
x-y = 60
When x is divided by y, the quotient is 3 and the remainder is 12.

The quadrants are generated when the two axes, the x-axis and the y-axis, cross at a 90-degree angle. These areas include coordinates, or positive and negative values of the x- and y-axes. The intersection of the x-axis (the horizontal number line) and the y-axis in the cartesian system divides the coordinate plane into four equal pieces (the vertical number line).

true/false if y is a differentiable function of u and u is a differentaible function of u and u is a differentaible function of x, then y is a differentiable function of x
True. If y is a differentiable function of u and u is a differentiable function of x, then the chain rule states that y is a differentiable function of x.
The chain rule states that if y is a function of u and u is a function of x, then the derivative of y with respect to x is equal to the derivative of y with respect to u multiplied by the derivative of u with respect to x. This means that if y is a differentiable function of u and u is a differentiable function of x, then y is also a differentiable function of x.
In mathematics, a function is said to be differentiable at a point if it is possible to define the derivative of the function at that point. The derivative of a function is a measure of how the function changes as its input (or independent variable) changes. It is defined as the limit of the difference quotient, which is a measure of the rate of change of the function over a small interval around the point of interest.

In some cases, the work capability amount cannot be included in your award right away; instead, there is typically a three-month "waiting period." When you submit supporting medical documentation to the Department of Work and Pensions, this will ordinarily start. You should take the work capacity evaluation while you're waiting.
