Answer:
OK so, starting from left to right it should be -1.75, -3/4, 1/4, 0.75, 1 1/2
Step-by-step explanation:
Simply go from the smallest to the largest number.
If it's a negative the bigger the number is actually going to be less.
Answer:
165 ways to choose the paintings
Step-by-step explanation:
This is clearly a Combination problem since we are selecting a few items from a group of items and the order in which we chosen the items does not matter.
The number of possible ways to choose the paintings is;
11C3 = C(11,3) = 165
C denotes the combination function. The above can be read as 11 choose 3 . The above can simply be evaluated using any modern calculator.
The correct answer to this question is this one: "D. 11.474"
your calculator probably doesn't do "secant". But sec is 1/cos
so do cos(85) (in degree mode, not radian mode)
then "invert it": 1 / ANS or x^-1 if you have that key
or type
1/cos(85 degrees)= <span>11.4737</span>
Answer:
1/2
Step-by-step explanation:
The slope of the points (4,-3) and (3,-1) is -2
The slope of a line perpendicular to said points would be the opposite reciprocal which would be 1/2
heres how you'd find the initial slope of the points
(4, -3)
-1 +2
(3, -1)
Slope= rise/run= 2/-1= -2
