Answer:
tan(x-y) = -16/63
Step-by-step explanation
Tan(x-y) if cscx=13/5 and coty=4/3
Given
coty = 4
1/tany = 4/3
Cross multiply
tan y = 3/4
Also since cscx = 13/5
1/sinx = 13/5
sinx = 5/13
Since sinx = opp/hyp
opp = 5
hyp = 13
Get the adjacent
hyp² = opp²+adj²
13² = 5²+adj²
adj² = 13² - 5²
adj² = 169 - 25
adj² = 144
adj = 12
cosx = adj/hyp
cosx = 12/13
tanx = sinx/cosx
tanx = (5/13)/(12/13)
tanx = 5/13 * 13/12
tan x = 5/12
tan(x-y) = tanx - tany/1+tanxtany
tan(x-y) = (5/12 - 3/4)/1+(5/12)(3/4)
tan(x-y) = (5-9/12)/1+5/16
tan(x-y) = -4/12/(21/16)
tan(x-y) = -1/3 * 16/21
tan(x-y) = -16/63
Answer:
b
Step-by-step explanation:
Answer:
A. 2,400π cubic units
Step-by-step explanation:
The answer is 4,000 ft squared because since the sides are 100 ft and 80ft then we need to multiply them which is 8,000 then divide that by 2 since it’s a triangle which is 4,000 ft squared.
Checking Account Advantages
Checking account holders have access to online and mobile banking, ATMs and the use of debit cards and checks to make purchases or withdraw funds from the account. Many employees find checking accounts useful for direct deposit of their paychecks. With direct deposit, an employer automatically transfers a payroll amount into the employees banking account, saving time and avoiding trips to the bank to cash paychecks. Most checking accounts in the United Stated are also insured by the Federal Deposit Insurance Corporation, or FDIC, for up to $250,000, which ensures an account holder that his money is safely stored at the bank.
couldn't really find a list besides knowing its a easier way to give money when you dont have any on you.
