Express as a product: 1-2cos(2a)
I've been really struggling with this. Please help & explain it.
Answer:
(2sin a - 1)(2sin a + 1)
Step-by-step explanation:
Here, we want to express what is given as a product
Mathematically;
cos2a = 1-2sin^2A
So we have;
1-2(1-2sin^a)
= 1 - 2 + 4sin^2a
= 4sin^2a - 1
Using the difference of two squares, this is;
(2sin(a) - 1)(2sin a + 1)

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. a) Simplify the expression and explain each step. (2 points) 4 ( 3 x + 2 ) − 2 b) Factor the expression completely. (1 point) 20 b − 16
Answer:
Step-by-step explanation:
To simplify the expression:
4(3x+2) - 2
The first step is to open the brackets
= 4 * 3x + 4* 2 - 2
= 12x + 8 - 2
= 12x - 6
Factor out the above expression, we get;
= 6(2x - 1)
To factor out the expression:
20b - 16
the factor that can be divided by 20 and 16 without remainder is 4;
So, we have:
= 4(5b - 4)

Tomas combines 8.73 ounces of strawberries with 8.86 ounces of blueberries to make fruit bowls. He pours the fruit equally into 4 bowls, and has 0.23 ounces of fruit left over. How many ounces of fruit are in each bowl?
Answer:
8.73 Ounces
Step-by-step explanation:
8.73 + 8.86 = 17.59
17.59 - 0.23 = 17.36
17.36 divide by 4 = 8.73
Each bowl has 4.46 ounces of fruit.
What is division?The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.
Now it is given that,
ounces of strawberries = 8.73 ounces
ounces of blueberries = 8.86 ounces
So, total ounces of fruits = 8.73 ounces + 8.86 ounces
⇒ total ounces of fruits = 17.59 ounces
Left over fruit = 0.23 ounces
So, total ounces of fruit in all bowls = 17.59 ounces - 0.23 ounces
⇒ total ounces of fruit in all bowls = 17.82 ounces
Since there are 4 bowls.
Thus, ounces of fruit in each bowl = 17.82/4 ounces
⇒ ounces of fruit in each bowl = 4.46 ounces
Thus, Each bowl has 4.46 ounces of fruit.

On a town map, each unit of the coordinate plane represents 1 mile. Three branches of a bank are located at A(−3, 1), B(2, 3), and C(4, −1). A bank employee drives from Branch A to Branch B and then drives halfway to Branch C before getting stuck in traffic. What is the minimum total distance the employee may have driven before getting stuck in traffic? Round to the nearest tenth of a mile if necessary.
The minimum total distance the employee may have driven before getting stuck in traffic is
miles.
Answer:
7.6 miles
Step-by-step explanation:
Given the coordinate points :
A(−3, 1), B(2, 3), and C(4, −1)
Distance (d) between A and B:
x1 = - 3 ; x2 = 2 ; y1 = 1 ; y2 = 3
d = √(x2 - x1)² + (y2 - y1)²
d = √(2 - (-3))² + (3 - 1)²
d = √25 + 4
d = 5.385 miles
BC :
d = √(x2 - x1)² + (y2 - y1)²
d = √(4 - 2)² + (-1 - 3)²
d = √2² + (-4²)
d = √4 + 16
d2 = 4.4721359 miles
(1/2) of d2 = 1/2 * 4.4721359 = 2.236 miles
Total distance = (5.385 + 2.236) miles
Total distance driven before getting stuck in traffic = 7.6 miles
the graph shows the height of a thrown ball x seconds after it is thrown. based on the situation, are there any constraints on the domain of the function
Answer:
The time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].
In other words, t ≥ 0.
Step-by-step explanation:
We know that the domain of a function is the set of input or argument values for which the function is real and is defined.
Given that the graph is showing the height of a thrown ball x seconds after it is thrown.
We must check that the time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].
In other words, t ≥ 0.

During migration ... This area is predominantly covered in forests. ... These colonies are dense, with between six and sixty million butterflies per hectare.
Answer:
80,000,000
Step-by-step explanation:
The difference between 10,000,000 and 50,000,000 is 40,000,000 per hectare. The question states two hectares, so 40,000,000 x 2 is 80,000,000.

Step-by-step explanation:

The answers to each part is given below.
What is percentage?In mathematics →
a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".Given is that you buy a watch for $60.
{a} -Total cost of watch -
{C} = ${60 + (6% of 60)}
{C} = ${60 + (6/100 x 60)}
{C} = $(60 + 3.6}
{C} = $63.6
{b} -New sale price -
{D} = 60 - (15% of 60)
{D} = 60 - (15/100 x 60)
{D} = 60 - 9
{D} = $51
{c} -Total cost of watch including tax -
{CT} = 51 + (6% of 51)
{CT} = 51 + 3.06
{CT} = 54.06
Therefore, the answers to each part is given above.

Jordan is using a six-sided number cube to predict whether people shopping in the mall arrive by car or by bus. Based on data gathered in a survey, Jordan decided that a roll of 1 or 2 would represent a person having taken the bus, while any other outcome would represent arriving by car.
Answer:
1/3 of the people come by bus
2/3 of the people come by car
Step-by-step explanation:
The probability of getting a 1 or 2 by rolling the six sided number cube is
P ( 1or 2) = 1/6 + 1/6= 2/6= 1/3
The total probability is always 1 so to get the probability of people arriving by car we subtract the probability of people arriving by bus from 1.
P ( not getting 1 or 2) = 1- P ( 1or 2)
= 1- 1/3= 2/3
The probability of people arriving by bus is 1/3 and the probability of people arriving by car is 2/6or 2/3.

The answer is C.As Jordan conducts more trials, the percent of people predicted to take the bus will approach 33%. PLS MARK ME BRAINLYIEST PLS

FIND THE AREA OF THE SEGMENT AYB. IF RADIUS OF THE CIRCLE IS 21cm AND ANGLE AOB= 120 DEGREE ( use pie= 22/7)
PLZ answer very urgent
Answer:
The area of the segment AYB is 271.0413985 cm²
Step-by-step explanation:
The rule of the area of a sector is A = [tex]\frac{\alpha }{360}[/tex] × π r², where
α is the central angle of the sectorr is the radius of the circleThe area of a triangle is A = [tex]\frac{1}{2}[/tex] × s1 × s2 × sinФ
s1 and s2 are two sides of the triangleФ is the included angle between s1 and s2∵ Area of the segment AYB = Area the sector AOB - Area ΔAOB
∵ The radius of the circle is 21 cm
∴ r = 21 cm
∵ The central angle of the sector is 120°
∴ α = 120°
∵ π = [tex]\frac{22}{7}[/tex]
→ Substitute them in the rule of the area of the sector to find it
∵ Area sector AOB = [tex]\frac{120}{360}[/tex] × [tex]\frac{22}{7}[/tex] × (21)²
∴ Area of sector AOB = 462 cm²
∵ OA and OB are the radii of the circle
∴ s1 = OA and s2 = OB
∴ s1 = s2 = 21 cm
∵ The angle included between them is 120°
∴ Ф = 120°
→ Substitute them in the rule of the area of the triangle to find it
∵ Area of the Δ = [tex]\frac{1}{2}[/tex] × 21 × 21 × sin(120)
∴ Area of the Δ = 110.25√3 cm²
∵ Area of the segment AYB = Area the sector AOB - Area ΔAOB
∴ Area of the segment AYB = 462 - 110.25√3
∴ Area of the segment AYB = 271.0413985 cm²
