5 to the second power (5^2)

Dmitry [639]3 years ago

5 0

Answer:

5^2 (that just means 5 to the second power you can write it as just a tiny 2 next to the 5) × X + 3. so in total it is 5^2 x X + 3.

At a movie theater, Ellie paid $8 for her ticket.Candy at the theater is 3.25.she had a total of $25 to spend. What is the maxim

BartSMP [9]

Answer:

Step-by-step explanation:

Answer is 5 candies.

$25 is her total amount so you need to subtract the $8 that she paid for her ticket with.

The answer to that subtraction is $17.

With $17, you divide by $3.25 (price of candy) to get the number 5.2. Except, you can't buy a small bit of a candy, so you would be able to buy 5 in total.

A golf-course architect has six linden trees, four white birch trees, and three bald cypress trees to plant in a row along a

JulijaS [17]

Total number of trees n = 4 + 3 + 3 = 10. Count the number of each different trees. n1=4, n2=3, n3=3. Number of ways the landscaper plant the trees in a row is = 10 ! / ( 4! * 3! * 3! ) = 3628800 / ( 24 * 6 * 6 ) = 3628800 / 864 = 4200 ways.

Therefore, the trees can be planted 4200 ways

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
