Answer:
Step-by-step explanation:
the expression we have is:
Because it is a product of two square roots, we can put it together in one:
and we carry out the multiplication inside the square root
(to multiply the variable x we sum the exponents 3+5=8)
and now we can take the square root of 36 which is 6.
and to take the square root if we divide the exponent by 2:
the simplified product is:
Answer: 61 people have worked on this worksheet so far.
Step-by-step explanation:
Given: 80% people try to do this ratio and proportion worksheet find they need some help with the problems.
Let x be the total number of people worked on this worksheet so far.
People need some help with the problems. =80% of x = 0.80x
As per given,
0.80x=49
Hence, 61 people have worked on this worksheet so far.
Calculate the hypotenuse( h ) using Pythagoras' identity
h =√(4² + 7²) = √(16 + 49) = √65
sinΘ = 4 / √65 ⇒ cscθ = √65 / 4
cosθ = 7/ √65 ⇒ secθ = √65 / 7
tanθ = ⇒ cotθ =
