if cos(x)=-1/4 and tan(x)<0 what is sin(2x)
By definition of tangent,
tan(x) = sin(x) / cos(x)
so if tan(x) < 0, and we're given cos(x) = -1/4 < 0, then it follows that sin(x) > 0.
Recall the Pythagorean identity:
cos²(x) + sin²(x) = 1 → sin(x) = + √(1 - cos²(x))
Then
sin(x) = √(1 - (-1/4)²) = √(15/16) = √(15)/4
Recall the double angle identity:
sin(2x) = 2 sin(x) cos(x)
Then
sin(2x) = 2 • √(15)/4 • (-1/4) = -2√(15)/16 = -√(15)/8

Water. 2 tbsp
Solution:
The ratio of cups of flour to tablespoons of peanut butter if Felipe makes 3 batches of dog treats is, 1/4
What is the ratio?A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.
Given that,
Felipe makes 3 batches of dog treats
The recipe for peanut butter dog treats,
(Ingredient) (amount)
Peanut butter 4 tbsp
Flour 1 cup

For 3 batches
Peanut butter required = 3 × required for one batch
= 3 × 4
= 12 tbsp
Flour Required = 3 × required for one batch
= 3 × 1
= 3
the ratio of cups of flour to tablespoons of peanut butter = 3/12

Ex plane how knowing 50 x 4 = 200 helps you find 500 x 400
Answer:
Step-by-step explanation:
if you know 50*4=200, you must also know that 50*10=500 and that 4*100=400 so 500*400= 50*10*4*100
multiplication is comutative so
50*4*10*100=200*1,000= 200, 000

Please help with the question below in the picture.
Answer:
Both ate 52 degrees
Step-by-step explanation:
You can find the measure of angle 5 by subtracting 128 from 180, which equals 52. From there you can deduct that angles 3 and 1 are congruent to 5, making them both 52 degrees.
I don't know what this equals??
Answer:
A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.
Step-by-step explanation:
The total sum of the interior angles of a simple decagon is 1440°
Determine the value of x in the diagram below
Answer:
x =32
Step-by-step explanation:
create equation
180 = 3x + 20 + 2x
combine like terms
180= 3x + 20 + 2x
180=5x + 20
subtract 20 from both sides of the equation
180=5x + 20
180-20= 5x +20 -20
simplify
160= 5x
divided both sides by 5
160/5=5x/5
solution
32= x
the ratio of 5 more than a number to 20 less than that number is 8:3. What is the number?
Answer:
35
Step-by-step explanation:
Let the number = y ;
5 more than the number = y + 5
20 less than that number = y - 20
Ratio = 8:3;
Solution:
Ratio of the number:
[tex]\frac{y + 5}{ y -20}[/tex] = [tex]\frac{8}{3}[/tex]
Now cross multiply and solve for y;
3(y+5) = 8(y-20)
3y + 15 = 8y - 160
3y - 8y = -160 - 15
-5y = -175
y = 35

Mr. Martinez's limo drove 15 miles south to Candy Land for some delicious gumdrops, then 5 miles east to Chuck E. Cheese for some scrumptious pizza. How far is Mr. Martinez from his starting point? Round your answer to the nearest tenth if necessary.
Answer:
15.8 miles
Step-by-step explanation:
Given that:
Distance driven south = 15 miles
Distance driven east = 5 miles
How far is Mr. Martinez from his starting point?
Using Pythagoras :
Distance from starting point(d) :
d = √(15)² + (5)²
d = √225 + 25
d = √250
d = 15.811388
d = 15.8 miles
