Answer:
m∡A = 14
m∡B = 76
Step-by-step explanation:
Two Angles are Complementary when they add up to 90 degrees.
So 3x -7 + 11x - 1 = 90, which we can solve.
14x - 8 = 90
14x = 98
x = 98/14 = 7
with the knowledge of x=7, we can find the angles:
m∡A = 3·7 - 7 = 14
m∡B = 11·7 - 1 = 76
Supplementary angles are angles that add up to 180 degrees, so the next assignment is very comparable, try it!
the function y = 3 ( ½)^3
is an exponential function and the graph should be
decreasing because there is a fraction term in the expression, the graph should
be from a very large number to almost zero. The graph may be a or b
but it should not reach negative so the answer is b
The 2 legs of the triangle could be 12 and 9 (they would fit the Pythagoras theorem).
The first choice fits these reuirements
Answer is (-5, 6), (-5, -6) (4,-6)
Answer:
The area is 29 cm
Step-by-step explanation:
Since it's kinda hard to divided 11, I divided 6 by 2 to get 3. You get the area by multiplying. So there are three 3's, but one of them is redundant, so we multiple 3 x 3, which is 9. Then we multiply 11 by the other half, 3. 11 x 3 = 33. Then the same thing with the bottom. We half 6, 3, and them multiply it by the width. 3 x 3 = 9. Then we add them all up. 9 + 9 = 18 + 11 = 29 cm
The sample space is nothing but ALL possible outcomes. In this case you have Black & Red id's. Then the sample space is {black, red}
