Answer:
hypotenuse
Step-by-step explanation:
Remember that when using sin and cos functions, the hypotenuse is always included as the denominator of the equation EXCEPT when you're solving with tan, which is opposite/adjacent.
If the two angles are supplementary, they must equal 180 degrees
Answer:
C)
B)
C)
Step-by-step explanation:
<h3>Question-1:</h3>
recall the surface area formula of cylinder
given that,h=5 and r=0.7
substitute:
simplify parentheses:
simplify multiplication:
hence, our answer is C
<h3>Question-2:</h3>
remember the surface area formula of cone
given that,r=7 and s=10
substitute:
simplify parentheses:
simplify multiplication:
hence, our answer is B
<h3>Question-3:</h3>
now for the question-3 we need a little bit understanding
remember the surface area formula of cube
we are given that, Thus
substitute:
divide both sides by 6:
square root both sides:
hence, the measurement of each
edge is 10 cm therefore our answer is C)
Answer:
Step-by-step explanation:
Given <u>v</u> = < - 5, 9 > then the magnitude is
| <u>v</u> | = = =
Answer:
The answer should be A
Step-by-step explanation:
Because 1/5k - 2/3j would be -2/3 j with 1/5 k missing which would mean it's the same as if you added it on instead of removing it
