A student solved the equation sin2x/cosx=2, 0(greater than or equal)x(greater than or equal)pi, and found an answer of pi/2. Describe the student's error.
Please show all steps.
Answer:
The student forgot about the double angle identity.
Step-by-step explanation:
sin2x/cosx=2
This is the double angle identity
sin2x=2sin(x)cos(x)
(2sinxcosx)/cosx=2
2sinx=2
sinx=1
x=sin^-1(1)
x=90 degrees OR pi/4

Which expression is equivalent to 5 + 15x?
0 A. 5(1 + 3x)
ОВ. 1(5 + 3x)
Ос. 3(5 + х)
OD. 5(3x)
оооо
Answer:
A. 5(1 + 3x)
Step-by-step explanation:
5(1 + 3x)
(5 × 1) + (5 × 3x)
5 + (5 × 3x)
5 + 15x
A works. Let's check the rest.
1(5 + 3x)
(1 × 5) + (1 × 3x)
5 + (1 × 3x)
5 + 3x
B does not work.
3(5 + х)
(3 × 5) + (3 × x)
15 + (3 × x)
15 + 3x
C doesn't work.
5(3x)
5 × 3x
15x
B, C, and D do not work.
Please someone help!! I tried my best to complete this problem but i'm stuck now (also am i even doing it right so far??!);(
Answer and Step-by-step explanation:
You got everything correct so far except for #4.
4. Yes, it is 1. But it would be in months.
So you would put:
1 month = x
12 months = 1 year.
Since the population increases by 1.5 times a month.
For question number 3.
The equation should be:
[tex]f(x) = 100(1.5)^x[/tex] <- Function
[tex]f(x) = 100(1.5)^{12}[/tex] <- Function when x is 12 months (1 year)
(Put those both the same way I put it.)
It gives you the equation to work with, you just have to plug in the values.
1.5 is in the parenthesis because it needs to be the one that is raised by an exponent.
100 is the initial population, so it stays on the outside.
x is the exponent

One angle of an isosceles triangle measures 32°. Which other angles could be in that isosceles
triangle?
Answer:
32° and 116°
Step-by-step explanation:
An isosceles triangle has two equal angles and the other angle is found by subtracting the sum of the two equivalent angles from 180°.
Since, one of the angles are given in the problem, one of the angles is 32°.
To find the other angle, we subtract the two angles from 180°.
180° - 32° - 32°
116°
The other two angles are: 32° and 116°

A game company asked people at the mall which game console they owned. They recorded the results in the bar graph below. How many more people owned a Xbox 360 than owned a Gameboy?
Answer:
Option (4)
Step-by-step explanation:
From the bar graph given in the picture,
Number of people who owned a Xbox 360 = 8
Similarly, number of people who owned Gameboy = 1
Therefore, difference in the number of people having Xbox 60 and Gameboy = 8 - 1
= 7
Option (4) is the correct option.

Given the definitions of f(x) and g(x) below, find the value of g(f(-1)).
f(x) = 3x² + 5x – 7
g(x) = 2x + 13
Answer:
-5
Step-by-step explanation:
At first,
f(-1) = 3 x (-1)² + 5 x (-1) -7
= 3 - 5 - 7
= -9
g(f(-1)) = g(-9)
= 2 x (-9) + 13
= -18 + 13
= -5

identify the domain and range of the relation
{(4, 2), (1, 3), (0, 0), (-1, -1), (1, -3)
Answer:
So, the domain are:
[tex]x = 4,1,0,-1[/tex]
The range are:
[tex]y = 2,3,0,-1,-3[/tex]
Step-by-step explanation:
Given:
[tex]\{(4, 2), (1, 3), (0, 0), (-1, -1), (1, -3)\}[/tex]
Required
The domain and the range
In relation, we have:
[tex]\{(x_1, y_1), (x_2, y_2), ......, (x_n, y_n)\}[/tex]
Where the x values are the domain and the y values represent the range.
So, the domain are:
[tex]x = 4,1,0,-1[/tex]
The range are:
[tex]y = 2,3,0,-1,-3[/tex]

Answer:
The n-th term of this sequence appears to be
3
n

Step-by-step explanation:
These are powers of
3
ordered from
3
0

to
3
a
(for an integer
a
≥
1
). However, the first convenient value for
n
is
1
, not
0
(imagine saying the 0th term of a sequence). Because of that, since the first term is actually

Answer:
8/17
Step-by-step explanation:
The lengths of the legs of a right triangle are 8 yards and 15 yards. What is the length, in yards, of the third side of the triangle?
A.23
B.17
C. 12.7
D.11.5
Answer:
B
Step-by-step explanation:
By inspection it can' be C or D since they are shorter than the 15 yard side.
Also B is just slightly big than 15, so it is mostly likely incorrect
I would guess A is the answer, proven to be INCORRECT see below
the correct answer is B. 17 yards
check the answer using the pythagorean theorem
a² + b² = c²
a = 8
b = 15
c = √(64 + 225)
= √289
= 17 my guess was wrong!!!!
