f(3) is ___
Answers
Answer:
f(3) is - 1
Step-by-step explanation:
f(3) means the function value when x = 3
3 is in the domain, the function value is in the range.
Thus when x = - 3 → y = - 1
f(3) is - 1
The value of given mapping diagram for function f(3) is - 1
What is Mathematical function ?
Mathematical function is the representation of relation between independent variables and dependent variables.
Here is given mapping diagram f(3) means the function value x = 3
3 is in the domain which is independent of range as shown in diagram.
Thus when x = 3 the range is approaching towards y = - 1
therefore, f(3) equals - 1

Rebecca wants to bye cupcakes and juice boxes for a party.Cupcakes come in packages of 12, and juice boxes come in packages of 10. She wants an equal number off cupcakes and juice boxes.What is the fewest number of packages of each Rebecca should buy?
Answers
2 is the highest number that both 10 and 12 are divisible by
hope this helps
Answer:
Rebecca would need to buy 5 packages of cupcakes and 6 packages of juice boxes
Step-by-step explanation:
To find the equal number of cupcakes and juice boxes, you have to find the LCM(least common multiple)
12×1 = 12 ≠ 10 ×1 = 12
12×2 = 24 ≠ 10×2 = 20
12×3 = 36 ≠ 10×3 = 30
12×4 = 48 ≠ 10×4 = 40
12× 5 = 60 ≠ 10×5 = 50
12 × 5 = 60 = 10×6 = 60
Therefore, Rebecca would need to buy 5 packages of cupcakes and 6 packages of juice boxes

A radar operator on a ship discovers a large sunken vessel lying parallel to the ocean surface, 120 m directly below the ship. The length of the vessel is a clue to which wreck has been found. The radar operator measures the angles of depression to the front and back of the sunken vessel to be 55° and 46°. How long, to the nearest tenth of a metre, is the sunken vessel?
Answers
Answer:
The length of the sunken vessel, to the nearest tenth is 200 m
Step-by-step explanation:
The given information are;
The depth of the sunken vessel below the ship = 120 m
The angle of depression to the front of the sunken vessel = 55°
The angle of depression to the back of the sunken vessel = 46°
Therefore, we have;
The length, A, of the from directly below the ship to the front of the sunken vessel given as follows;
Tan(55°) = ((120 m)/A)
A = 120 / Tan(55°) ≈ 84.025 m
The length, B, of the from directly below the ship to the back of the sunken vessel given as follows;
tan(46°) = ((120 m)/B)
B = 120 / tan(46°) ≈ 115.88 m
The length, L, of the sunken vessel = A + B
L = A + B = 120 / Tan(55°) + 120 / tan(46°) ≈ 84.025 m + 115.88 m ≈ 199.91 m
∴ The length, L, of the sunken vessel, to the nearest tenth = 200 m.

Enter a recursive rule and an explicit rule for the arithmetic sequence. Then, find the 20th term of the

55, 65, 75, 85,-
The recursive rule is f(1) =
f(n)=f(?
+
The explicit rule is f(n) =
+
?
f(20) =
Answers
Answer:
The recursive rule is [tex]f(1)[/tex] = first term; [tex]f_({n})[/tex] = [tex]f_({n-1})[/tex] + d
f(1) = 55; [tex]f_{20}[/tex] = [tex]f_{19}[/tex] + 10
The explicit rule is f(n) = f(1) + (n - 1)d
f(20) = 245
Step-by-step explanation:
The recursive rule of the arithmetic sequence is
[tex]a_{1}[/tex] = first term; [tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + d
Where:
[tex]a_{1}[/tex] is the first term in the sequence [tex]a_{n}[/tex] is the nth term in the sequence [tex]a_{n-1}[/tex] is the term before the nth term n is term number d is the common difference.The explicit rule of the arithmetic sequence is
[tex]a_{n}=a_{1}+(n-1)d[/tex]
where:
[tex]a_{1}[/tex] is the first term in the sequence [tex]a_{n}[/tex] is the nth term in the sequence n is term number d is the common difference∵ The first 4 terms of the sequence are 55, 65, 75, 85
∴ [tex]a_{1}[/tex] = 55
∵ d = 65 - 55
∴ d = 10
∵ We need to find the 20th term
∴ n = 20
∵ The recursive rule is [tex]f(1)[/tex] = first term; [tex]f_({n})[/tex] = [tex]f_({n-1})[/tex] + d
→ Substitute the values of [tex]a_{1}[/tex], n, and d in recursive rule
∴ f(1) = 55; [tex]f_{20}[/tex] = [tex]f_{19}[/tex] + 10
∵ The explicit rule is f(n) = f(1) + (n - 1)d
→ Substitute the values of n and d to find it
∴ f(20) = 55 + 19(10) = 245
∴ f(20) = 245

I had the same question a couple years back and this paragraph really helped me out, hopefully it does the same for you. The coordinate plane is a way that we have to locate points in two dimensions. It consists of two intersecting lines that we call axes. The axes are number lines with positive and negative values. The horizontal line is referred to as the x-axis, and the vertical line is the y-axis. The coordinate plane is divided into four quadrants. These quadrants are named with Roman numerals and are numbered starting in the top, right section and moving counter-clockwise.

Answer:

Step-by-step explanation:
there are 5 x's and 1 positive one of the left side, and 3 x's and five positive one's on the right side. when you put this into an equation, you get:
5x+1 = 3x+5
the first step to solving the equation is to subtract 3x from both sides:
5x+1 -3x = 3x+5 -3x
2x+1 = 5
next, subtract 1 from both sides:
2x+1 -1 = 5 -1
2x=4
finally, divide both sides by 2:
2x ÷2 = 4 ÷2
x=2

The range is the set of output values.
The given relation is a function.
Zero is included in the range of the relation.

Explanation:
Choice A is false because the domain consists of the x values, not the y values. The domain is the set of allowed inputs.Choice B is true because the range is the set of possible output y values.Choice C is false because the input x = 5 leads to multiple outputs (y = -3 and y = 2 at the same time). Plotting all the points on the same xy grid shows the relation fails the vertical line test.Choice D is false because y = 0 is not in any of the points. Choice E is true since x = 5 is part of (5,-3) and (5,2)Answer:

The fourth choice. For example, (x+2)(x-2)>0 we'll get x>2 or x<-2 because whenever you substitute x>2 for example x = 3, the value will be higher than 0 itself.
If we substitute x = 3 (for x>2)
We'll get (3+2)(3-2)>0
5(1)>0
5>0 The statement is true.
If we substitute x = -3 (for x<-2)
We'll get (-3+2)(-3-2)>0
-1(-5)>0
5>0 The statement is true.
We don't say x>2 AND x<-2, In math, we only say x>2 OR x<-2
Answer:
x >2 and x < -2
Step-by-step explanation:
The line on the right starts on -2 and goes towards -10
