Answer:
27
Step-by-step explanation:
note that tanx cotx = tanx ×
= 1
Given
tanx - cotx = 5 ( square both sides )
(tanx - cotx)² = 5² = 25 ← expand left side using FOIL
tan²x - 2tanxcotx + cot²x = 25
tan²x - 2 + cot²x = 25 ( add 2 to both sides )
tan²x + cot²x = 27
The last one hope this helps
Y=Mx+b b is always on the y intercept so that canceled out c and b is canceled out Bc the Mx is negative and it can’t just be 6 Bc there is no point on where it clear like right on the point if u can understand that so that just leaves u with d y=-7/6x-7
It’s 8sqrt3 . You can use the Pythagorean theorem- A squared plus B squared equals C squared. You can plug them and getting eight squared plus B squared equals 16 squared. Eight squared is 64 and 16 squared is 256. Subtract 64 from 256 and that leaves you with eight square root of three
Answer:
9x + 4y < 110
Step-by-step explanation:
This inequality works because its the cost of hammers ($9) multiplied by how many hammers are bought (x) plus the cost of wrenches ($4) multiplied by how many wrenches are bought (y). The total cost has to be less than 110.
