Cos30*cos50+sin30*sin50
9514 1404 393
Answer:
cos(20°)
Step-by-step explanation:
The angle difference formula for cosine is ...
cos(α -β) = cos(α)cos(β) +sin(α)sin(β)
If we let α = 50° and β = 30° then this matches the given expression:
cos(50° -30°) = cos(50°)cos(30°) +sin(50°)sin(30°) = cos(20°)
Consider the sequence whose first five terms are shown. -59 ,-67 ,-65 ,-53 ,-31 ,... The first term is ____ To calculate the second term, add _____ To calculate each additional term, increase the amount added by _____ (the _____ are blanks)
Step-by-step explanation:
The sequence is as follows :
-59 ,-67 ,-65 ,-53 ,-31 ,...
The first term = -59
The second term = -67
Common difference = second term - first term
[tex]=-67-(-59)\\\\=-8[/tex]
To calculate the second term add (-8).
To calculate each additional term, increase the amount added by -8.

Answer:
9 = probably D(maybe A)
I'm not sure what the answer is for #9 but I think it is most likely D. A is multiply 6 by 4 which would be substituting the value of w, for w. D is adding 2 to 40 which is combining like terms.

Write an equation of the line through the point (-10, 0) with slope of -1/2
Answer:
y = 1/2x + 5
Step-by-step explanation:
We can use point slope form since we are given a point and the slope
y -y1 = m( x-x1)
where ( x1,y1) is a point and m is the slope
y -0 = 1/2 (x- -10)
y = 1/2( x+10)
y = 1/2x + 5
help me with this please ill PayPal you money
Answer:
well ofc you can say the totally like area i think its called is 1428 you could multiply 6 to 14 the sum would be 84 you could divide 1428 by 84 and get 17 which is the value of x and if you divide 1428 by 6 on accident you would get 238 and you could check your work and see that 6 x 238 would be 1428 but that wouldnt be correct bc you only have 2 didgets and as you can your dealing with two and finding another one so that would be three didgets so ye

The horizontal axis label is Days, and the vertical axis label is Cost of Rental in dollars. Points are plotted on the ordered pairs 2, 1 and 4, 2, and 6, 3.
Answer:
This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.

So how do i do like Rule: y=x+3 and the boxes are like X Y ? 4 ? 8 ? 5 like how
Answer:
X: 1 5 2
Y: 4 8 5
Step-by-step explanation:
Given
[tex]Rule: y = x + 3[/tex]
X: ? ? ?
Y: 4 8 5
Required
Fill in the ?'s
We have that:
[tex]y = x + 3[/tex]
When y = 4; the rule becomes
[tex]4 = x + 3[/tex]
Subtract 3 from both sides
[tex]1 =x[/tex]
[tex]x =1[/tex]
When y = 8; the rule becomes
[tex]8 = x + 3[/tex]
Subtract 3 from both sides
[tex]5= x[/tex]
[tex]x =5[/tex]
When y = 5; the rule becomes
[tex]5 = x + 3[/tex]
Subtract 3 from both sides
[tex]2 = x[/tex]
[tex]x = 2[/tex]
So, the complete table is:
X: 1 5 2
Y: 4 8 5
A bag contains 70 pencils out of which 15 are green and 30 are blue. How many pencils of other colour are in the bag. A pencil is selected from a bag at random .What is the probability that it is blue?
Answer:
a) There are 25 pencils of other colour in the bag.
b) P(Blue) = 3/7
Step-by-step explanation:
A bag contains 70 pencils out of which 15 are green and 30 are blue.
a) How many pencils of other colour are in the bag?
This is calculated as:
70 - (15 + 30)
= 70 - 45
= 25 pencils
Hence, there are 25 pencils of other colour in the bag.
b) A pencil is selected from a bag at random .What is the probability that it is blue?
P(Blue) = Number of Blue pencils/Total number of Pencils
P(Blue) = 30/70
P(Blue) = 3/7

Sketch the graph of 2y=f(3x-6) -2
Um i think 2yyyy =f 3x-6
The required graph is attached below, which represents the given function f(x)= 3x - 6y - 2.
The below graph of the function f(x) = 3x - 6y - 2 represents a straight line in a two-dimensional coordinate system.
The equation is in standard form, where x and y are variables and the equation is equal to a constant value (-2 in this case).
To graph this equation, we can rearrange it to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.
By isolating y in the equation, we get y = (3/6)x - 2/6, which simplifies to y = (1/2)x - 1/3.
The slope of the line is 1/2, meaning for every increase of 1 in the x-coordinate, the y-coordinate increases by 1/2.
The y-intercept is -1/3, which is where the line crosses the y-axis.

-2(p - 1) = 15 helllp plss slol
Answer:
-13/2
Step-by-step explanation:
Answer:
P = -6.5
Step-by-step explanation:
Multiply -2 x p and -2 x -1
The equation now is -2p + 2 = 15
Subtract the 2 to both sides to cancel it out
The equation now is -2p = 13
Divided both sides by -2 to isolate the p variable
p = -6.5
You can check your answer by subtracting -6.5 by -1 (which equals -7.5)
And then multiply -7.5 by -2 which equals 15
A department store purchases screen-printed t-shirts at a cost of $5 per shirt. They mark up the price 150% (making the selling price 250% of the store's purchase price) and put them on the sales floor. Every month that a t-shirt doesn't sell, the store reduces the selling price by 25%.
Which expression shows the selling price after one monthly price reduction?
$5 + $5(1.50) – $5(0.25)
$5 + ($5)(0.25) – ($5)(1.50)

What is Least Common Multiple?Least Common Multiple is the meaning of the abbreviation LCM. The lowest number that may be divided by both numbers is known as the least common multiple (LCM) of two numbers. It can also be computed using two or more numbers. Finding the LCM of a given collection of numbers can be done in a variety of ways.
In mathematics, the least common multiple is sometimes referred to as LCM or the lowest common multiple. The smallest number among all the common multiples of the provided numbers is the least common multiple of two or more numbers.
Given:
Matt practice every fourth day.
I practice on 3rd days
Now, to find the first date on which they both have practice we have to find the LCM
So, 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40

15 points and BRAINLIEST Alyssa invested $500 into an account. The value of the account after t years can be found using the function r(t) = 500(1.068). What is the percent annual rate of change
in the value of the account?
Answer:
annual rate: r = 0.068
Step-by-step explanation:
The formula is r(t) = P(1+r)^t
Since the time is already in years we just have to solve for the rate
1 + r = 1.068
r = 0.068
The rate of change in the value of account is 0.068
What is rate of change?
'Rate of change is used to mathematically describe the percentage change in value over a defined period of time.'
According to the given problem,
Annual rate:
r = 0.068
The formula is r(t) = [tex]P( 1 + r )^{t}[/tex]
Therefore, solving for the rate
⇒ 1 + r = 1.068
