From the function f(x) = x^2 + 3, calculate: (2 points) a) The change in y when x varies from 4 to 4.5

b) The increment of the function when x = 2 and Δx = 0.01.

2.- Calculate the approximate value of the increment of the function () = 2^3 + 5, consider what’s indicated in the following points:

a) x changes from 3 to 3.02.

b) When x = 2 and Δx = 0.001

3.- Calculate the approximate decrease in the area of a circular burn when the radius decreases from 2 to 1.98 cm.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

i saw this question before, dont know the asnwer srry

step-by-step explanation:

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.

step-by-step explanation:

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
