To force floating-point output to show the decimal point and trailing zeros, use the ________ manipulator.
Answers
To force the output to show the decimal point and trailing zeros of a decimal number use the showpoint, manipulator.
The showpoint function is a manipulator that sets the show point flag, which instructs an output stream to write a decimal point for floating-point output, even if the point is superfluous. This is done by setting the showpoint flag, which is done by setting the show point flag (only zeros appear after the decimal point). More specifically, the calls to the functions.
The distinction between a whole number and the fractional component of a number is denoted by the use of a symbol known as a "decimal point," which can be either a point or a dot. A different name for it is the Decimal Mark. The representation of the decimal point is the (.). In addition to using whole numbers, we frequently work with decimals.

Which graph shows the sequence –7, –4, –1, 2, ...?
Answers
The first graph is the answer
This graph represents −x−2y=−4 .
Which ordered pair is in the solution set of −x−2y≤−4 ?
A. (−4, 1)
B. (−1, 4)
C. (−4, −1)
D. (4, −1)
Answers
Answer:
B
Step-by-step explanation:
We have the equation \(-x-2y=-4\) and we want to find which ordered pair is in the solution \(-x-2y\leq -4\)
First, let's convert the inequality to slope-intercept form. So, we have:
\(-x-2y\leq-4\)
Add x to both sides:
\(-2y\leq x-4\)
Divide both sides by -2. Since we're dividing by a negative, we will flip the sign:
\(y\geq- \frac{1}{2}x+2\)
Therefore, our original inequality will be the same as above.
Notice that our y is greater than our equation.
Therefore, the shaded area will lie above our line.
So, any point that falls within the region above our line (in the graph) and on the line is a solution to our inequality.
(-4, 1) is below our line, so it's not a solution.
(-1, 4) is above our line. So, (-1, 4) is our answer.
(-4, -1) is again below our line. So, it's not a solution.
Finally, (4, -1) is also below our line, so it's not a solution.
Therefore, our final solution is B: (-1, 4).
Let's check this. Substitute -1 for x and 4 for y. This yields:
\(-(-1)-2(4)\stackrel{?}{\leq}4\)
Multiply:
\(1-8\stackrel{?}{\leq}{4}\)
Subtract:
\(-7\stackrel{\checkmark}{\leq}4\)
So, (-1, 4) is indeed our solution.

Monica has recently inherited $6100, which she wants to deposit into a savings account. She has determined that her two best bets are an account that compounds semi-annually at an annual rate of 2.6% (account 1) and an account that compounds daily at an annual rate if 4% (account 2). How much would Monica's balance be from account 2 over 5.9 years?
Answers
Monica's balance from account 2 over 5.9 years would be approximately $7892.99.
We have,
To calculate Monica's balance from account 2 over 5.9 years, we can use the formula for compound interest:
\(A = P(1 + r/n)^{nt}\)
Where:
A = the final balance
P = the initial principal (amount deposited)
r = the annual interest rate (expressed as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
For account 2, the annual interest rate is 4% (0.04) and it compounds daily, so n = 365.
Plugging in the values into the formula, we have:
\(A = 6100(1 + 0.04/365)^{365 \times 5.9}\)
Calculating the expression inside the parentheses:
\((1 + 0.04/365)^{365 \times 5.9} = 1.293082\)
Now, we can calculate the final balance:
A = $6100 x 1.293082 ≈ $7892.99
Therefore,
Monica's balance from account 2 over 5.9 years would be approximately $7892.99.

Answer:
f(x): Amplitude = 2, Period = 2
g(x): Amplitude = ¹/₂, Period = π
Step-by-step explanation:
The cosine function is periodic, meaning it repeats forever.
Standard form of a cosine function:
f(x) = A cos(B(x + C)) + D
where:
A = amplitude (height from the mid-line to the peak)2π/B = period (horizontal distance between consecutive peaks)C = phase shift (horizontal shift - positive is to the left)D = vertical shiftFunction f(x)
\(f(x)=2 \cos (\pi x)\)

Since the measurements in meters are multiples of 4, it makes this problem a little easier.
First you divide 8 by 4 to get 2
Then divide 16 by 4 to get 4
After that you're going to multiply 3 units by both quotients separately.
So you multiply 3 by 2 to get 6
