Rounding to the nearest tenth, which of the following give an overestimate? Choose all that apply.
A. 45.07 × 3.45
B. 19.74 × 5.53
C. 8.16 × 60.29
D. 2.92 × 77.81
E. 32.86 × 10.4

 C. 8.16 x 60.29

Step-by-step explanation:

8.16 x 60.29 = 491.9664

When you round the nearest tenth which is 9, it'll be estimated to a 10. The numbers would then be 492.0 which is a overestimate.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
