91 x 89 = 8099, so if you round 8099 to the nearest hundred, then you would get 8100.
Answer:
397,800
Step-by-step explanation:
8,840 × 45 = 45 × 8,840 = 397,800
Answer:
Approximately mMK is 53 degrees
Step-by-step explanation:
Here, we want to find the length of MK
As we can see, we have a right triangle at LNK
so
let us find the angle at L first
9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L
so the trigonometric identity that connects adjacent to the hypotenuse is the cosine
It is the ratio of the adjacent to the hypotenuse
So;
cos L = 9/15
L = arc cos (9/15)
L = 53.13 degree
Approximately, L = 53 degrees
so now, we want to get the arc length MK
We are to use the angle-arc relationship here
Using this; arc length MK is equal to the measure of L at the center which is 53 degrees
The answer would be
3x² + 6
6 because 4 is lower than 5 so then you need to give it a rest
