Answer:
3/20
Step-by-step explanation:
First simplify the fractions
2/10 Divide top and bottom by 2
= 1/5
9/12 Divide top and bottom by 3
= 3/4
2/10 * 9/12
1/5*3/4
Multiply the top
1*3 = 3
Multiply the bottom
5*4=20
3/20
Both are incorrect insofar that they say that they use the word always, which certainly is not the case. If the poly has a degree of 2, and a vertex which is for example (0, 5) the line y = x
would never intersect it. Y = x + 5 would intersect it at one point,
and y = x+10 at two points. The answer also depends on the delta of the function. If delta greater than 0 there will be two solutions, while a delta that is 0 gives one solution.
If delta is smaller than 0 we have no solution.
Answer:
0.93 radians to 2D.P's.
Step-by-step explanation:
sin O = 4/5 / 1 = 0.8
So < O = 0.927 radians .
Answer:
a = 2
b = 4
Step-by-step explanation:
In parallelogram opposite sides are equal.
4a + b = 2a + 8
4a - 2a + b = 8
2a + b = 8 -----------------(I)
b = 8 - 2a
11b - 10a = 6b
11b - 6b -10a = 0
5b - 10a = 0 ---------(II)
Substitute b = 8 - 2a in equation (II)
5*(8-2a) - 10a = 0
5*8 - 2a * 5 - 10a = 0
40 - 10a - 10a = 0
40 - 20a = 0
-20a = - 40
a = -40/-20
a = 2
Plugin a = 2 in equation (I)
2*2 + b = 8
4 + b = 8
b = 8 -4
b = 4
Answer:
9 free-throws
Step-by-step explanation:
75% of 36 = 27
36-27=9
She could have missed up to nine free throws
