Evaluate the expression below when n = 2.4. If needed, answer as a fraction or a decimal.
12n−8
Answers
Answer:
20.8
Step-by-step explanation:
Plug in 2.4 as n in the expression, and simplify:
12n - 8
12(2.4) - 8
28.8 - 8
= 20.8
So, the answer is 20.8

The path of a flying fish as it made its approach to the surface of the ocean and flew out of the water is represented by the quadratic function h(t) = -t2 + 6t - 5, where t represents the time, in seconds, and h(t) represents the fish's height and depth, in feet. Graph the function using the graphing calculator. To the nearest second, how long was the fish out of the water?
1 second
3 seconds
4 seconds
5 seconds

The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3
Answers
Answer:
50 times
Step-by-step explanation:
Total number of faces = total possible outcomes = 8
Number of 2 or 3 on spinner = required outcome = 2
Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes
P(2 or 3) = 2 / 8 = 1/ 4
From 200 ; prediction for the number of 2 or 3
1/4 * 200
= 50 times

The solution of this trigonometric identity is [tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex].
Step-by-step explanation:
Let [tex]7\cdot \tan \theta - 8 = 5\cdot \tan \theta -5[/tex], we proceed to simplify the expression and solve afterwards either by algebraic or by trigonometric means:
[tex]7\cdot \tan \theta -8 = 5\cdot \tan \theta -5[/tex]
[tex]2\cdot \tan \theta = 3[/tex]
[tex]\tan \theta = \frac{3}{2}[/tex]
[tex]\theta = \tan^{-1} \frac{3}{2}[/tex]
The tangent is a trigonometric function with a period of 180°. Hence, we find that the family of angles associated with such value is:
[tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex]

21. identify the secant that intersects OA.
Answers
=============================================================
Explanation:
A secant line cuts the circle so that part of the line is inside the circle, and the rest (or majority) of the line is outside the circle. In other words, the secant line intersects the circle at exactly two points.
This is in contrast to a tangent line that only touches the circle at exactly one point. Line L is the tangent line in this case.
Segment DC is a diameter of the circle as it goes through the center, and this segments endpoints are on the circle's edge. The segments AD and AC are radii of the circle.

In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?
Answers
Answer:
12 quarters
Step-by-step explanation:
number of quarters ---------x
number of dimes ------------y
therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1
0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2
equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12
there are 12 quarters

Find the midpoint of the line segment whose endpoints are the given points. (-24.6, 38.1) and (-25.7, -17.7)
Answers
Answer:
Midpoint is[tex](-25.15,10.2)[/tex]
Step-by-step explanation:
A line segment refers to line that has two endpoints.
Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.
Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]
Take the given points as follows:
[tex](a,b)=(-24.6,38.1)\\(c,d)=(-25.7,-17.7)[/tex]
Midpoint of a line segment [tex]=(\frac{-24.6-25.7}{2},\frac{28.1-17.7}{2})[/tex]
[tex]=(\frac{-50.3}{2} ,\frac{20.4}{2} )\\=(-25.15,10.2)[/tex]

Since its a 45-45-90 triangle then the 2 legs are going to be the same.
Answer:
90°
Step-by-step explanation:
Always remember that the sum of all angles is 180°.
So there are two 45° angles, so just add them up and you get 90
So if you subtract 90 from 180, you get 90, and that's your answer
Whats the area of the rectangle?
Length: 2 1/7
width: 3 1/3
I dont need an explanation just the simplified answer
Answers
Answer:
The area of rectangle is "31 units²".
Step-by-step explanation:
The given values are:
Length of rectangle,
= [tex]\frac{21}{7}[/tex]
Width of rectangle,
= [tex]\frac{31}{3}[/tex]
As we know,
The area of rectangle is:
= [tex]Length\times width[/tex]
On substituting the values, we get
= [tex]\frac{21}{7}\times \frac{31}{3}[/tex]
= [tex]\frac{217}{7}[/tex]
= [tex]31 \ units^2[/tex]
