Answer:
Positive is 1
Negative is-1
Step-by-step explanation:
Answer:
a = 4
Step-by-step explanation:
a^2 + b^2 = c^2
a= ?
b= 3
c= 5 (c is always the hypotenuse)
*plug in given values
a^2 + 3^2 = 5^2
a^2 + 9 = 25
-9 -9
a^2 = 16
*find the square root
sqrt(a) = sqrt(16)
a = 4
First you need to find the y-intercept, which is y = -1
Next is we need to find the slope of the line > you are going to have to do this by finding to clear point
The ones that I will be using are: (3, 1); (6, 3) (You could take any points)
Now using the slope formula we could find m.
m = y2-y1 / x2-x1
(1 - 3) / (3 - 6) = m
-2 / -3 = m
m = 2/3
Using the linear function format: y = mx + b
Therefore the equation of the line is y = 2x/3 -1
The simple answer (not using multiples of 2
(360°)) is
![= \sqrt[3]{125} ((cos( \frac{288}{3})) + isin(( \frac{288}{3}))) = 5(cos96 + isin96)](https://tex.z-dn.net/?f=%3D%20%20%5Csqrt%5B3%5D%7B125%7D%20%28%28cos%28%20%5Cfrac%7B288%7D%7B3%7D%29%29%20%2B%20isin%28%28%20%5Cfrac%7B288%7D%7B3%7D%29%29%29%0A%3D%20%205%28cos96%20%2B%20isin96%29)
Answer: $7
Step-by-step explanation:
Let x = Cost of each T-shirt.
As per given,
Total charge =( Number of t shirts x Cost per t shirt )+ set up fee
For 21 T-shirts , total charge would be : 21x+40
According to the question
⇒21x+40=187
⇒21x = 187-40
⇒21x = 147
⇒x= 7
Hence, each T-shirt costs $7 .
