Answer:
9.9 feet per second
Step-by-step explanation:
y=9.5+0.4
y=9.9
Marcella's average speed in feet per seconds is,
⇒ y = 9.54 feet
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The equation which represents the line of best fit for the distance in feet) that Marcella traveled over time (in seconds) based on several races she ran is,
⇒ y = 9.50x + 0.4
Hence, Marcella's average speed in feet per seconds is,
y = 9.50x + 0.4
Put x = 1;
y = 9.50 × 1 + 0.4
y = 9.50 + 0.4
y = 9.54 feet
Thus, Marcella's average speed in feet per seconds is,
⇒ y = 9.54 feet

Answer: Choice D) As the side length increases by 1, the area increases and then decreases by an equal factor
=============================================================
Explanation:
Choice A is ruled out because the area does change. As x changes, y changes as well. This rules out choice B as well.
Choice C is somewhat close. However, it's not entirely true since the area doesn't increase by the same amount. For instance, the jump from points (2,18) to (3,24) indicate that the jump in y value is +6. But going from (3,24) to (4,28) shows a jump of +4 in the y value. So we can rule out choice C.
This means that choice D is the final answer.
Mai is playing a game with a class of second graders. Mai knows she is exactly 120 inches from the mirror on the floor. She has students stand so that she can just see the top of their heads and then guesses their heights. The students are amazed!
Diagram of 2 stick figures.
How is Mai so accurate?
Mia is able to find the height of the students so accurately using the tangent property of trigonometry.
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
As it can be seen that there are two right triangles, therefore, using the tangent property of the trigonometry, Mia is able to find the height of the students so accurately.

What are the one-sided limits around the discontinuity
shown in the graph?
The one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.
What is a discontinuous function?Discontinuous functions are functions that do not have a continuous curve - there is a hole or jump in the graph.
In the shown graph of the function, the function is discontinuous at x=-3
[tex]\lim_{x \to \ -3} g(x)[/tex] tends to infinity so [tex]\lim_{x \to \ -3} g(x)[/tex] does not exist.
[tex]\lim_{x \to \ +3} g(x)=0[/tex]
Hence, the one-sided limits around the discontinuity shown in the graph are infinity and zero i.e. option 2.

Answer:
Given:
ΔFGH ≅ ΔWAXCorresponding sides or angles are congruent
Segment GH ≅ Segment AX∠W ≅ ∠ F7. What is the slope of the line that passes through the points (14, -18) and (5, -12)?
Answer:
slope =[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope, or [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:
[tex]m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}[/tex]
Thus, the slope is [tex]-\frac{2}{3}[/tex].
What is the answer to 5m + 30 = 60
Answer:
m = 6
Step-by-step explanation:
Given
5m + 30 = 60 ( subtract 30 from both sides )
5m = 30 ( divide both sides by 5 )
m = 6
