The number 9,839,038 after indicated rounding off gives the number 9,839,000.
What is Rounding Off?Rounding off of a number is defined as the simplification of the number by keeping the value of the number same but is made closer to the next number.
Rounding can be done for whole numbers as well as decimals.
Given is a whole number 9,839,038.
We have to round it to the place shown where the digit is 9.
Look at the next digit right to 9.
It is 0, which is less than 5.
So replace all the digits next to 9 by 0.
We get the number 9,839,000.
Hence the rounded number is 9,839,000.

Evaluate the indefinite integral. (Use C for the constant of integration.) sin(16x) J 1 + cos2(16x) - dx -tan-|(16x)I+C
The indefinite integral of sin(16x) with respect to x cannot be expressed in terms of elementary functions.
LaTeX, you can display powers using the caret (^) symbol. For example, to display x raised to the power of 2, you would write:
[tex]$x^2$[/tex]
And to display x raised to the power of y, you would write:
[tex]$x^y$[/tex]
To solve this integral, we would typically use numerical or approximate methods, or special functions such as the sine integral or Fresnel integrals.
The indefinite integral of [tex](1 + cos^2(16x))[/tex] with respect to x can be evaluated using the substitution u = cos(16x). The derivative of cos(16x) with respect to x is -16sin(16x), so the integral becomes:
[tex]∫ (1 + cos^2(16x)) dx = ∫ (1 + u^2) du[/tex]

Option b is the correct answer. It varies from one climograph to another; there is no standard length of time.
A climograph is a graphical representation of climate data that shows the average temperature and precipitation patterns over a certain period of time. The length of time represented on a climograph can vary and there is no set standard. It could be a few months, a year, several years, or even decades. It depends on the specific data and purpose of the climograph. Some climographs may show data from the last 30 years, while others might show data from the last 300 years. The important thing to remember is that the length of time represented on a climograph will vary and there is no set rule for how long it should be.

a restaurant offers delivery for pizzas. The total cost includes $11 per pizza and the delivery fee. A delivery of 5 pizzas costs $58.
Write an equation to represent the total cost, y for x number of pizzas. Use your wquation to find the cost of delivery of 80 pizzas.
Answer:
y=883
Step-by-step explanation:
The total cost includes $11 per pizza and the delivery fee. A delivery of 5 pizzas costs $58.
11 (dollars per pizza) x 5 (pizzas were delivered) = 55 dollars
58 (total cost) - 55 (total cost for pizza) = 3 (fee)
11x+3=y (Equation)
input the 80 pizzas to the equation
11(80)+3=y
y= 883

What is composite functionA function is composite when the co-domain of the first mapping is the domain of the second mapping
We shall evaluate the domain of the function (f - g)(4) as follows:
(f - g) = 4x - 3 - (x³ + 2x)
(f - g) = 4x - 3 - x³ - 2x
(f - g) = 2x - 3 - x³
(f - g)(4) = 2(4) - 3 - (4)³
(f - g)(4) = 8 - 3 - 64
(f - g)(4) = -59

A baker is packaging her cupcakes into single serve boxes for a special event. Each
cube-shaped box has side lengths 3.5 inches (in.). The smaller boxes are then packed into a
larger box with dimensions of 10.5 in. x 7 in. x 7 in.
Please help me I have my math class tomorrow and tomorrow is also when it is due!!!
Answer: Sure! I'd be happy to help you with this.
To find the number of cupcake boxes that fit in the larger box, we need to find the volume of the larger box and divide it by the volume of one cupcake box.
The volume of the larger box is 10.5 x 7 x 7 = 572.5 cubic inches.
The volume of one cupcake box is 3.5 x 3.5 x 3.5 = 42.375 cubic inches.
Dividing the volume of the larger box by the volume of one cupcake box, we get 572.5 / 42.375 = 13.5.
So, 13.5 cupcake boxes will fit in the larger box.

An artist invests in a mutual fund account paying 5% and $5000 more than four times as much in a mutual fund account paying 4%. Her total annual interest income from the investments is $1145. How much does she invest at each rate?
The artist invests $4500 in the 5% account and $23000 in the 4% account.
Let's call the amount invested in the 5% account x. Then, the amount invested in the 4% account is 4x + 5000.
The total annual interest income from the investments is 1145, so we can write an equation:
0.05x + 0.04(4x + 5000) = 1145
Expanding the second term:
0.05x + 0.04(4x) + 0.04(5000) = 1145
0.05x + 0.16x + 200 = 1145
0.21x + 200 = 1145
0.21x = 945
x = 4500
So the artist invests $4500 in the 5% account and $18000 + 5000 = $23000 in the 4% account.

Line t 1 is a common internal tangent to C 1 and C 2 and has a positive slope and line t 2 is a common internal tangent to C 2 and C 3 and has a negative slope. Given that lines t 1 and t 2 intersect at (x,y) and that x=p−q√r, where p,q and r are positive integers and r is not divisible by the square of any prime, find p+q+r.a.P+Q+R=26b.P+Q+R=24c.P+Q+R=28d.P+Q+R=27
The sum of p, q, and r is 27.
The point of intersection of the lines t1 and t2, (x,y), can be found by using the equation of the lines. The equation of t1 is y=mx+c, where m is the slope, and c is the y-intercept. The equation of t2 is y=mx+c, where m is the slope, and c is the y-intercept.
The equations of t1 and t2 can be written as y= 1/2 x + 1 and y= -1/4 x + 7/2 respectively.
By setting the two equations equal to each other, we can find the x-coordinate of the point of intersection (x,y).
x=2 - 7/4 =4/4 - 7/4 = -3/4
Since x=p−q√r, we can write -3/4 = p−q√r.
Rearranging this equation, we get p+q+r= 4/3 + 7/3 + 4/3 = 27/3 = 9.

The order of asymptotic magnitude is (3!)3 < 3n < n log(3n) < n3 < 3n < 3n. This means that the function with the smallest asymptotic magnitude is (3!)3, while the function with the largest asymptotic magnitude is 3n.
To confirm this, let's calculate the growth rate of each function. The growth rate of (3!)3 is 3!3 ≈ 216, which is less than the growth rate of 3n (3n) = 3n, which is greater than the growth rate of n log(3n) (n log3n) = n log3n, which is greater than the growth rate of n3 (n3) = n3, which is greater than the growth rate of 3n (3n) = 3n, which is greater than the growth rate of 3n (3n) = 3n.

Mr Saver invests $X at t = 0 in an account that pays a nominal rate of R convertible
quarterly. The interest he earns during t = 0.5 to t = 1.5 is 1.0816 times the interest
he earns during t = 0 to t = 1. Find the exact value of R.
Let X be the amount Mr Saver invests at t = 0.
The interest he earns during t = 0 to t = 1 can be expressed as:
Interest = X * R * (1/4)
The interest he earns during t = 0.5 to t = 1.5 can be expressed as:
Interest = X * R * (3/4)
Since the interest he earns during t = 0.5 to t = 1.5 is 1.0816 times the interest he earns during t = 0 to t = 1, we can set up the following equation:
X * R * (3/4) = 1.0816 * (X * R * (1/4))
Solving for R, we get:
R = 4.3264 Therefore, the exact value of R
