Answer:
B
Step-by-step explanation:
The volume of model a is 36 because 3 * 2 * 6 = 36, and the volume of model b is 40 because 2 * 2 * 10 =40.
W is in the lower left corner located at (-1,-2)
W' is in the upper left corner located at (-2,1)
Notice that the original Y value (-2) became the new X value (-2) and the original X value (-1) is the inverse of the new Y value (1).
If you look at the coordinates of the other two pints you would see it was the same transformation.
When the X and Y coordinates switch like this, it is a 90 degree clockwise rotation around the origin.
Answer:
6x+20 or 2(3x+10)
Step-by-step explanation:
Six friends went to a basketball game and four people paid $5 extra for a t-shirt. To find the total cost, multiply 6 by x and 4 by 5 this add them together:
6*x+4*5
6x+20, If needed you can factor this expression to:
2(3x+10)
La respuesta es B a+10b+6c=62
1. Given any triangle ABC with sides BC=a, AC=b and AB=c, the following are true :
i) the larger the angle, the larger the side in front of it, and the other way around as well. (Sine Law) Let a=20 in, then the largest angle is angle A.
ii) Given the measures of the sides of a triangle. Then the cosines of any of the angles can be found by the following formula:
a^{2}=b ^{2}+c ^{2}-2bc(cosA)
2.
20^{2}=9 ^{2}+13 ^{2}-2*9*13(cosA) 400=81+169-234(cosA) 150=-234(cosA) cosA=150/-234= -0.641
3. m(A) = Arccos(-0.641)≈130°,
4. Remark: We calculate Arccos with a scientific calculator or computer software unless it is one of the well known values, ex Arccos(0.5)=60°, Arccos(-0.5)=120° etc
