Answer:
c is correct
Step-by-step explanation:
if u have the equation y = a sin b (x),
a is the amplitue (regardless of + or - before it) and 2pi / b = period. so we can deduce that a = +5 or -5 and b = 2, but then it says a>0, so therefore a must be 5 and b is still 2, so the equation is y= 5 sin2(O)
In the diagram, x is a negative number and y is a positive number. Select the expression that is a positive.
Answer choices:
x(y)
x - y
y/x
y - x
Answer:
Option 4: y -x
Step-by-step explanation:
Option 1
Multiplying a positive and a negative number will result in a negative number.
For example, if x= -1 and y=5,
x(y)= -1(5)= -5 (a negative number)
Thus, option 1 is incorrect.
Option 2
In this option, we are essentially multiplying -1 to y, a positive number, before adding the result with x.
Since y is a positive number, -y is a negative number and hence x -y (when x is a negative number) will result in a negative number. Let's plug in values into x and y to check this.
For example, x= -2 and y=3.
x -y= -2 -3= -5
Option 2 is thus incorrect.
Option 3
Dividing a positive number with a negative number will result in a negative number.
For example: 6÷(-2)= -3
Option 3 is also incorrect.
Option 4
Subtracting a negative number from a positive number will result in a positive number.
For example: x= -1, y= 8
y -x= 8 -(-1)= 8 +1= 9
As seen from the example above, when the negative number is multiplied to negative 1, a positive sign results.
In summary, when a positive number is multiplied to a positive number, the resulting number is positive.
When a negative number is multiplied to a negative number, the resulting number is positive.
When a positive number is multiplied to a negative number, the resulting number is negative.
+(+)= +
-(-)= +
+(-)= -
This applies to division too.

A school has a parking lot that is 150.23 feet by 135.12 feet. What is the perimeter of the parking lot?
Answer: 570.70 ft
Step-by-step explanation:
The perimeter is the distance around the entire parking lot.
The measurement of 150.23 ft by 135.12 ft is half of the distance of the lot because it represents just two sides yet there are 4 sides.
The other two sides have the same measurement as this is a rectangle.
The perimeter of the parking lot is:
= (150.23 * 2) + (135.12 * 2)
= 570.70 ft
At a school picnic, 80 students ordered hot dogs and 63 hamburgers. Of those, 14 students ordered both a hot dog and hamburger. If there were 180 students at the picnic, how many students did not offer a hot dog or hamburger
Answer:
The answer should be 37
Step-by-step explanation:
Find the interest on $4,000 at 3% for 4 months.
Answer:
$80 interest will be owed for 4 months
Step-by-step explanation:
P is the principal amount, $4000.00.
r is the interest rate, 8% per year, or in decimal form, 8/100=0.08.
t is the time involved, 3....month(s) time periods.
Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into "year" as well.
Do this by dividing your time, 3- month(s), by 12, since there's 12 months in 1 year.
So, t is 0.25....year time periods.
To find the simple interest, we multiply 4000 × 0.08 × 0.25 to get that

He bought 26 stamps
Step-by-step explanation:
13.66=.39x+4.30
9.36=.39x
26=x
Answer:
24 stamps
Step-by-step explanation:
13.66 - 4.3 = 0.39s
9.36 = 0.39s
Divide both sides by 0.39
24 = s
Or turn it:
s = 24

EMERGENCY!!!! Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer. (I've asked this question before but the answers I got were 384 and 64 and they were both wrong)
Answer:
After eight hours 6,561 people will know the rumor.
Step-by-step explanation:
Since each hour, every person who knows a rumor tells two other people, so that if one person starts the rumor, then after the first hour, three people know the rumor, and the next hour, those three people each tell two more people, to determine after eight hours, how many people will know the rumor, the following calculation must be performed:
Hour 0 = 1
Hour 1 = 1 + 2 = 3
Hour 2 = 3 + 2 x 3 = 9
Hour 3 = 9 + 2 x 9 = 27
Hour 4 = 27 + 2 x 27 = 81
Hour 5 = 81 + 2 x 81 = 243
Hour 6 = 243 + 2 x 243 = 729
Hour 7 = 729 + 2 x 729 = 2,187
Hour 8 = 2,187 + 2 x 2,187 = 6,561
Therefore, after eight hours 6,561 people will know the rumor.

what does 4x-2y=2 equal to step by step
Answer:
y = 2x - 1
Step-by-step explanation:
4x - 2y = 2
So I'm assuming that your goal is to solve for the value of y in terms of x
First: the whole equation can be divided by 2
2x - y = 1
Second: subtract 2x from both sides
-y = -2x + 1
Third: divide each side by -1
y = 2x - 1

can someone find the median mode and please show how you got it :)
you will get top answer
Answer:
mode = 2
Step-by-step explanation:
mode is the most frequently seen number.
median is the average so 5+4+2+2+2+2+1+1+3+2+2+3+3+2+1/15= 2 1/3
Answer:
Median is 2, Mode is 2
Step-by-step explanation:
1,1,1,2,2,2,2,2,2,2,3,3,3,4,5 to get the median you put the number from smallest to large then you x one out on each side until there is only one number left which would be 2
The mode is 2 because it is the most common number (aka it appears the most in the list)

What is the length of the missing side? 7 and 12
Answer: 9.75
Step-by-step explanation:
if the missing side is the leg of the triangle. 13.89 if missing side is the hypotenuse
To the nearest hundreth, what is the length of line segment AB?
1.) 2.45
2.) 2.16
3.) 7.75
4.) 8.25
Answer:
option (4)
Step-by-step explanation:
Calculate the length using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A(2, 2) and (x₂, y₂ ) = B(- 6, 4)
AB = [tex]\sqrt{(-6-2)^2+(4-2)^2}[/tex]
= [tex]\sqrt{(-8)^2+2^2}[/tex]
= [tex]\sqrt{64+4}[/tex]
= [tex]\sqrt{68}[/tex]
≈ 8.25 ( to 2 dec. places )
5/8 divided by 9
help
Answer:
5/72
Step-by-step explanation:
dividing is equivalent to multiplying by the reciprocal
5/8×1/9
multiply the fraction
8×9=72
5×1=5
Answer: 5/72
Answer:
5/8 / 9 = 5/72
Step-by-step explanation:
5/8 / 9 = 5/72
Anytime you divide with a fraction remember this:
Same, change, flip:
You keep the first fraction, which is 5/8, the same.
Then you change the division sign to a multiplication sign.
After that, you flip the 9/1 (which is the same thing as 9) to 1/9.
So it would be 5/8 x 1/9.
If you multiply that, you can 5/72.
Therefore, 5/72 is your answer.

Jabari owns 100 shares of Stock A and 45 shares of Stock B For the past month, his stocks have been fluctuating inversely. Stock A decreased
by m cents per
share and Stock B increased by n cents per share. Which equation can be used to find the total change in value of Jabari's
shares per month?
Answer:
Answer is
(100*-m)+(45*n)
Step-by-step explanation: because stock decreases per sock so you're going to multiply 100 times -m because it is decreasing so it will be negative
Then it will be 45*n because it increases per number of stocks so you multiply 45 which is the number of stocks times n
