Find all x that satisfy the given equation for 0<_x<2pi. Select all that apply. 2 cos^2x+cos x=0
Answer:
x=0 or 2pi/3
Step-by-step explanation:
2 cos^2x+cos x=0
cos x(2cos x+1)=0
cos x=0 or 2cos x+1=0
x=0 or cosx=-1/2
x=0 or 2pi/3
What is the value of x in the equation 2x - 3/5 = -1/10
Answer:
1/4
Step-by-step explanation:
you add 3/5 to the other side and find the lcm making it 6/10--1/10=5/10. Then 5/10 divided by 2 = 2.5/10 which you can simplify to 1/4.
Answer: x=1/4
Step-by-step explanation:
1. Isolate x: if you move -3/5 to the other side, your equation would become
=> 2x=-1/10+3/5
2. Find the common denominator: since you can't add -1/10 with 3/5 without simplifying, you're equation would change to this:
=> 2x=-1/10+6/10
3. Simplify:
=> 2x=5/10 => 2x=1/2
4. Divide:
=> 2x=1/2 => x=1/2*1/2 => x=1/4

3) A grocery store has cereal on sale. If the original price is $4.50 and the sale
price is $3, what percent is the discount?
Step-by-step explanation:
original price = $4.50
sale price = $3
discount price = $4.50 - $3
= $1.50
discount = discount percent × original price ÷ 100
$1.50 = discount percent × $4.50 ÷ 100
discount percent = $1.50 × 100 ÷ $4.50
= 33.33%

Answer:
x = 14
Step-by-step explanation:
Figure A to Figure B = 1:3.5 = 1/3.5
Therefore:
Side length of figure A to side length of figure B = 1/3.5
Thus:
4/x = 1/3.5
Cross multiply
x*1 = 3.5*4
x = 14

Use the Law of Sines to determine the length of
side c.
44°
B
29
49
34
21
Answer:
c = 29
Step-by-step explanation:
Law of sines is given as: [tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
B = 180 - (57 + 44) = 79°
b = 41
C = 44°
c = ?
Thus:
[tex] \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
Substitute
[tex] \frac{41}{sin(79)} = \frac{c}{sin(44)} [/tex]
Multiply both sides by sin 44
[tex] \frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44) [/tex]
[tex] \frac{41*sin(44)}{sin(79)}*sin(44) = c [/tex]
c = 29.0140633 ≈ 29

Answer:
110º
Step-by-step explanation:
Because the angle starts at 10º, and ends at 120º, so if we moved the angle down to start at 0º we would have to subtract 10º, so we must subtract 10º from 120º. You end up with 110º.

circler
called
Answer:
Radius.
Step-by-step explanation:
A line joining the center of a circle to a point on the circle is called a radius.
This ultimately implies that, it is the straight line from the center of a circle to any point on the edge of the circle. Also, radius is half of a diameter i.e diameter divided by the 2.
Generally, the radius is used for calculating the area and circumference of a circle.
Area of a circle = πr²
Circumference of a circle = 2πr
The S.I units for measuring radius is meters.

15 dollars on every purchase, he sold 11 TVs. So we find the total amount of money, 15*11=165
935-165=770
770 is the amount left without the money he has earned so the total base.
770/11=70
Checking answerLet's rebuild it to test if it is correct...
$70 for each tv * 11 tv's = $770 or the base price of the tv's
$15 for all the warranties
$15*11=165
165+770=935
So the answer is 70$
Hopefully, this helped.

A box of jerseys for a pick-up game of basketball contains 10 extra-large jerseys, 6 large jerseys, and 4 medium Jerseys. If you are first to the box and grab 2 jerseys, what is the probability that you randomly grab 2 medium jerseys? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Answer: 3/95
Total Number of jerseys:
10+6+4=20
Odds of first jersey being medium:
4/20
Odds of second jersey being medium
3/19
(4/20)*(3/19)=12/380=
6/190=3/95
The probability that you randomly grab 2 medium jerseys is 3.15%.
Since a box of jerseys for a pick-up game of basketball contains 10 extra-large jerseys, 6 large jerseys, and 4 medium Jerseys, to determine, if you are first to the box and grab 2 jerseys, what is the probability that you randomly grab 2 medium jerseys, the following calculation must be performed:
10 + 6 + 4 = 20 4/20 x 3/19 = X 0.0315 = X 0.0315 x 100 = 3.15%
Therefore, the probability that you randomly grab 2 medium jerseys is 3.15%.
