Answer:
108n
Step-by-step explanation:
88n+20n
=108n
This statement means that the diver is going 30 meters under sea level. It is negative because sea level is 0, and anything below 0 is a negative.
Answer:(0,0) (-1,0) (-1,3)
Step-by-step explanation:
scf 0.5 is shrinking the shape by a 1/2
The coordinates of a point of enlargment is (3,1)
so you work out the vectors of each corner than times it by 0.5
The vector of one cooridnate is (-6 -2)
-6x0.5=-3
-2x0.5=-1
so the vector is -3 -1 from the point of enlargment is the shape .
(-8 -2 ) is the coodinates of the next vector so
(-4 -1)
Then the last
(-8, 4)
(-4,2) vector for the last coodinate
sorry i couldn't write out the vector properly in the right notation .
Answer:
See below
Step-by-step explanation:
- <em>There is a formula for estimating square root of non-perfect square numbers</em>
- <em>√(A²±B) = A ± B/2A</em>
- <em>where A² is the nearest perfect square, B is the difference between the original number and the perfect square</em>
<u>Examples</u>
- 1) √75 = √(8²+11) = 8 + 11/(2*8) = 8 + 11/16 = 8.6875
- 2) √114 = √(11² - 7) = 11 - 7/(2*11) = 10.6818
