Answer:
46.19 feets
Step-by-step explanation:
Using Pythagoras rule :
Sin θ = opposite / hypotenus
Let length of string = s
Sin 60 = 40 / s
s * 0.8660254 = 40
s = 40 / 0.8660254
s = 46.188021 feets
s = 46.19 feets
It will take Kelley 9 hours because 540 miles (distance) divided by 60 mph (rate) will give you 9 hrs
Answer:
Output = 7
Step-by-step explanation:
Input value...is the value of x and the output value..is the value of y,
So the question is just saying that what is the value of y when x = 4
; 3(4) - 5
; 12 - 5
; y = 7...therefore the output value = 7
Intersection means elements both have. Both sets have -1 but they have nothing else in common so the intersection is {-1}
Union means combining the sets so {-1, 1, 2, 3, 7} Note that I only wrote 1 twice. No duplicates allowed!
Final result :
s6t5
Step by step solution :
Step 1 :
t
Simplify ——
r3
Equation at the end of step 1 :
t
((((r3)•(s4))•——)•s2)•t4
r3
Step 2 :
Multiplying exponential expressions :
2.1 t1 multiplied by t4 = t(1 + 4) = t5
Final result :
s6t5
