To get the growth factor from a percentage increase, express the percentage as a decimal, then add 1.
256% = 2.56
2.56 + 1 = 3.56

The appropriate choice is ...
c. 3.56

Answer:

missing value in the table is 3.56

Step-by-step explanation:

Percent 13% 256% 28% 97%

Growth Factor 1.13 ? 1.28 1.97

To find growth factor first we remove the percentage and then we add 1

we are given with 246 %

to remove percentage we divide by 100

$\frac{256}{100} = 2.56$

To get growth factor we add 1

1+2.56= 3.56

so growth factor is 3.56

missing value in the table is 3.56

What is the value of x?

Reika [66]

The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides
VT/TK = VY/YK
95.2/168 = 34/YK
YK = (168·34)/95.2 = 60 cm
x = VY + YK = 34 + 60 = 94 cm

Daniela is 23 years older than her daughter. in 5 years, their ages will total 63. how old are they now?

pshichka [43]

Both their ages totaled in 5 (years) - 5 (years)

63 - 5 = 58

Current ages totaled = 58 (years)

Daniela is 23 years older than her daughter (as given above) so...

Current ages totaled (58 years) - How many years Daniela is older than her daughter ( 23 years )

58 - 23 = 35

So, Daniela’s age is currently 35 years and her daughter’s age would be 23 years.

Determine whether the following statements are true and give an explanation or a counter example. a. The Trapezoid Rule is exact

Norma-Jean [14]

Answer:

statement is TRUE

statement is FALSE

statement is TRUE

Step-by-step explanation:

(a)

By using the Trapezoidal Rule, the definite integral can be computed by applying linear interpolating formula on each sub interval, and then sum-up them, to get the value of the integral

So, in computing a definite integral of a linear function, the approximated value occurred by using Trapezoidal Rule is same as the area of the region. Thus, the value of the definite integral of a linear function is exact, by using the Trapezoidal Rule.

Therefore, the statement is TRUE

(b) Recollect that for each rule of both the midpoint and trapezoidal rules, the number of sub-internals, n increases by a factor of a. then the error decreases by a factor of a^2.

So, for the midpoint rule, the number of sub-intervals, n is increased by a factor of 3, then the error is decreased by a factor of 32 = 9, not 8. Therefore, the statement is FALSE

(c) Recollect that for each rule of both the midpoint and trapezoidal rules, the number of sub-internals, n increases by a factor of a. then the error decreases by a factor of a^2.

So, for the trapezoidal rule, the number of sub-internals, n is increased by a factor of 4. then the error is decreased by a factor of 42 = 16

Therefore, the statement is TRUE
