What's ƒ(g(x)) if ƒ(x) = 3x + 7 and g(x) =6x – 5?
Answer:
ƒ(g(x)) = 18x - 8
Step-by-step explanation:
We're looking for the composition of f and g, in which function g is the input to function f. Literally replace "x: in f(x) with g(x) = 6x - 5:
ƒ(g(x)) = 3(6x - 5) + 7, or, after simplification,
ƒ(g(x)) = 18x - 15 + 7, or 18x - 8
Solve for z:−8(z+4)=−7(z+−4)+−3
Let's solve your equation step-by-step.

the box plot shows the leg lengths, in millimeters, of a sample of insects. what is the range of lengths of the insects?
The distance between the lower whisker and the minimum value and the distance between the upper whisker and the maximum value indicate the range of the leg lengths of the insects in millimeters.
A box plot, also known as a box-and-whisker plot, is a graphical representation of a dataset that displays the distribution of a continuous variable. It shows the minimum and maximum values, the first and third quartiles, and the median of the data. The length of the box in a box plot represents the interquartile range (IQR), which is the range between the first and third quartiles. The whiskers extend from the box to show the range of the data, excluding outliers.
In the context of the question, the box plot displays the leg lengths, in millimeters, of a sample of insects. To determine the range of lengths of the insects, we need to examine the whiskers of the box plot. The whiskers extend from the box to the minimum and maximum values of the dataset, and their length represents the range of the data.
Therefore, to answer the question, we need to look at the length of the whiskers in the box plot.
In conclusion, the range of lengths of the insects can be determined by looking at the length of the whiskers in the box plot. The answer will depend on the specific values displayed in the plot.

How can we determine whether the solution is a ray or a segment?
A ray has only one endpoint. A segment has two endpoints.
What is a line?
A line is an object in geometry that is infinitely long and has neither width nor depth nor curvature. Since lines can exist in two, three, or higher-dimensional spaces, they are one-dimensional objects. In everyday language, a line segment with two points designating its ends is also referred to as a "line."
A ray and a segment are parts of a line.
This line segment has two fixed-length endpoints, A and B. The distance between this line segment's endpoints A and B is its length.
In other words, a line segment is a section or element of a line with two endpoints. A line segment, in contrast to a line, has a known length.
A line segment's length can be calculated using either metric units like millimeters or centimeters or conventional units like feet or inches.
Ray has only one endpoint and the other ends go infinity.

Consider the figure shown with vertices O(0, 0) , A(- 4, 1); B(- 3, 5) and C(1, 4). Is this parallelogram a rectangle?
Based on the fact that the opposite sides are parallel and the diagonals are congruent, we can conclude that the parallelogram formed by the given vertices O, A, B, and C is indeed a rectangle.
To determine whether the parallelogram formed by the vertices O(0, 0), A(-4, 1), B(-3, 5), and C(1, 4) is a rectangle, we need to consider the properties of a rectangle.
A rectangle is a quadrilateral with four right angles (90 degrees each). We can examine the properties of the given parallelogram to determine if it satisfies these conditions.
First, we can calculate the slopes of the opposite sides of the parallelogram.
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:
slope = (y2 - y1) / (x2 - x1)
Using this formula, we can calculate the slopes of AB and OC:
Slope of AB = (5 - 1) / (-3 - (-4)) = 4/1 = 4
Slope of OC = (4 - 0) / (1 - 0) = 4/1 = 4
Since the slopes of the opposite sides AB and OC are equal, we can conclude that AB and OC are parallel.
Next, we can calculate the slopes of the other pair of opposite sides OA and BC:
Slope of OA = (1 - 0) / (-4 - 0) = 1/-4 = -1/4
Slope of BC = (4 - 5) / (1 - (-3)) = -1/4
Again, we find that the slopes of OA and BC are equal, meaning that OA and BC are parallel.
Since both pairs of opposite sides are parallel, this parallelogram satisfies one of the properties of a rectangle.
However, to confirm if it is indeed a rectangle, we also need to check if the diagonals are congruent (equal in length).
Let's calculate the lengths of the diagonals:
Length of diagonal \(AC = \sqrt{((1 - 0)^2 + (4 - 0)^2) }\)
\(= \sqrt{(1^2 + 4^2) }\)
= √17
Length of diagonal \(OB = \sqrt{((-3 - (-4))^2 + (5 - 1)^2) }\)
\(= \sqrt{(1^2 + 4^2) }\)
= √17.
Since the lengths of both diagonals AC and OB are equal, the parallelogram satisfies this additional property of a rectangle.

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k. (1 point) 92 fix)
Answer:
3
Step-by-step explanation:
g(x) = f(x) + k, is true for all values of x.
At x = 0, f(x) = 2
At x = 0, g(x) = 5
Therefore, at x = 0
=> g(x) = f(x) + k
=> 5 = 2 + k
=> 3 = k
Since, the given relation is true for all real values of x, k is independent of x. Thus k = 3, for every value of x
Find the surface area of the figure. Hint: the surface area from the missing prism inside the prism must be ADDED!
To find the surface area of the figure, we need to consider the individual surfaces and add them together.
First, let's identify the surfaces of the figure:
The lateral surface area of the larger prism (excluding the base)
The two bases of the larger prism
The lateral surface area of the smaller prism (excluding the base)
The two bases of the smaller prism
The lateral surface area of a prism is given by the formula: perimeter of the base multiplied by the height.
The bases of the prisms are rectangles, so their areas can be calculated by multiplying the length by the width.
To find the missing prism's surface area, we need to consider that it is a smaller prism nested inside the larger prism. The lateral surface area and bases of the missing prism should also be included.
Once we have calculated the individual surface areas, we add them together to find the total surface area of the figure.
Without specific measurements or dimensions of the figure, it is not possible to provide a numerical answer. Please provide the necessary measurements or dimensions to calculate the surface area.

What is function Composition?
Function Composition exists when two functions f(x) and g(x) result in another function h(x), such that h(x) = f(g(x)). In other words, put the outcome of one function into the other one.
Here, h(x) = f(g(x))
