15a^2+3ab-1, I would explain my answer, however, I would get deleted for copying something else which is ridiculous.<span />
To solve, you need to find the least common multiple of the denominator.
In this case, its 30.
3*9= 27/30
1*10 = 10/30
She walked 37/30 miles or 1 mile and 7/30th of a mile
I'm not going to give you the answer, but I'm going to give really obvious hints to you.
Supplementary angles are when two angles add up to 180 degrees.
Complimentary is when two angles add up to 90 degrees.
I'm not sure how you find angles m<y and m<v, I can't even see the letter m on the attachment.
There are two angles that are adjacent to <GXF, and you are free to choose which ever ones you like: <FXE and <CXG
Answer:
Area:
4 x 4 = 16
Finding area of semi circle:
4 is your diameter so half of it is your radius which is 2 since half of 4 is 2!
2^2<---your radius being squared = 4
4(radius squared) x 3.14(pi) = 12.56
12.56 divided by 2 since its a semi circle is = 6.28
6.28 + 16 = 22.28 is your area
Perimeter is:
4 + 4 + 4 (all sides of a square are equal therefore one or two given lengths will be all the sides) = 12
Circumference:
Radius is 2,
2(you just always have to multiply this number when finding circumference) x 3.14(pi) x 2(radius), 2 x 3.14 x 2 = 12.56
12.56 divided by 2 = 6.28
6.28 + 12 = 18.28 is your perimeter.
Just a refresh:
Circumference Formula:
2(always use this number when finding circumference) x pi(3.14 or 22/7 depending on what they tell you to use for pi) x radius
Area of a Circle Formula:
Radius squared x pi(3.14 or 22/7 whatever they tell you to use for pi)
Another thing you should remember:
Whenever it gives you 1/4 of a circle or 1/3 or a semi circle or any fraction, REMEMBER TO DIVIDE BY THAT DENOMINATOR TO WHAT YOU GET FROM EITHER CIRCUMFERENCE OR AREA OF A CIRCLE!
Answer:
Step-by-step explanation:
Since cotangent of angle is:
And
- cos λ = x/1, sin λ = y / 1
The value of cot λ is:
- cot λ = x/y = - 0.358/0.934 = - 0.383 (rounded)
Correct choice is B
