The width of each poster cannot be greater than 11/4 feet or 2.75 feet.
For given expression w represents the width, 4w represents the total width of four posters, 5 represents space between posters and edges of wall, and 16 represents width of the wall.
The boundary value satisfies the inequality.
In the given problem, Marie-Renee wants to hang 4 identical posters on her wall, and she needs to leave at least 5 feet of space total between the posters and between the edges of the wall. Let's assume that the width of each poster is w feet.
The inequality 4w + 5 ≤ 16 represents the maximum space the posters can take on the wall. In this inequality,
w represents the width of each poster,
4w represents the total width of four identical posters,
5 represents the total space between the posters and between the edges of the wall, and
16 represents the total width of the wall.
To find the acceptable width of each poster, we need to solve 4w + 5 = 16.
4w + 5 = 16
4w = 16 - 5
4w = 11
w = 11/4
So, the width of each poster cannot be greater than 11/4 feet or 2.75 feet.
Now, we need to check if the boundary value of w satisfies the original inequality or not.
4w + 5 ≤ 16
4(11/4) + 5 ≤ 16
11 + 5 ≤ 16
16 ≤ 16
Since the boundary value satisfies the inequality, the solution to Marie-Renee's inequality is w ≤ 11/4 or w ≤ 2.75 feet.
Therefore, the width of each poster cannot exceed 2.75 feet, and all four posters can be hung on the 16 feet wide wall with at least 5 feet of space total between them and the edges of the wall.

a. Express each of the following as a function of 15°
6. tan165°
7. sin285°
Expressing each as a function of 15°, we have 6. tan165° = tan(150 + 15)° and 7. sin285° = sin(270 + 15)°
Expressing each as a functionFrom the question, we have the following trigonometry function that can be used in our computation:
6. tan165°
7. sin285°
The above expressions are tangent and sine functions of 165 and 285 degrees
By mathematical expression, we have
165° = 150 + 15
285° = 270 + 15
This means that we can replace the expressions with 150 + 15 and 270 + 15
So in terms of 15 degrees, we have
6. tan165° = tan(150 + 15)° and 7. sin285° = sin(270 + 15)°

Answer:
a³ = -357911/5832.
Step-by-step explanation:
We can use the given equation to find the value of n, and then use it to find the value of a³.
a¹ = 13 and a = ⁿ⁻¹ - 4
Substituting the value of a in terms of n in the first equation, we get:
ⁿ⁻¹ - 4 = 13
ⁿ⁻¹ = 13 + 4
ⁿ⁻¹ = 17
ⁿ = 18
Now, substituting the value of n in the equation a = ⁿ⁻¹ - 4, we get:
a = 18⁻¹ - 4
a = 1/18 - 4
a = -71/18
Finally, to find a³, we can cube the value of a:
a³ = (-71/18)³
a³ = -357911/5832
Therefore, a³ = -357911/5832.

Write an explicit formula for an, the nth term of the sequence 25,30,35,....
Answer:
[tex]a_{n}[/tex] = 5n + 20
Step-by-step explanation:
there is a common difference between consecutive terms in the sequence
30 - 25 = 35 - 30 = 5
this indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + d(n - 1)
where a₁ is the first term and d the common difference
here a₁ = 25 and d = 5 , then
[tex]a_{n}[/tex] = 25 + 5(n - 1) = 25 + 5n - 5 = 5n + 20

A 2-column table with 4 rows. The first column is labeled x with entries 0, 0.5, 1, 1.5. The second column is labeled y with entries 40, 39.25, 38.5, 37.75.
If the Raj’s bathtub is draining at rate of 1.5 gallons of water per-minute, then the range will be (c) all real numbers such that 0 ≤ y ≤ 40.
The "Range" of function is defined as the set of all possible "output-values'.
The amount of water remaining in the bathtub is decreasing as it drains, so the range of the function is bounded below by 0 (because we cannot have negative water in the bathtub) and above by 40 (the initial amount of water in the bathtub).
Looking at the given values of y, we can see that the value of "y" lies between 0 and 40.

Note that the sequence of transformations that will move ABC onto DEF is; "The translation (x,y)->(x+7,y), followed by a dilation by a scale factor of 2 centered at the origin." *Option C)
What is transformation?A transformation is a mathematical function that repositions points in one-, two-, three-, or any other n-dimensional space.
A dilation is a function f from a metric space M into itself that fulfills the identity d=rd for all locations x, y in M, where d is the distance between x and y and r is some positive real integer. Such a dilatation is a resemblance of space in Euclidean space.
Note that translation takes B(0,0) to B'(7, 0),
Takes A(0, 4) to A'(7, 0) and C (3, 0) to C' (10, 0)

Answer:
D. Dilation by 2, translation right by 7.
Step-by-step explanation:
You want to know the sequence of transformations that maps ∆ABC to ∆DEF.
Scale factorSegment DE is 8 units long, and located at x=7. Segment AB is 4 units long and located at x=0.
The scale factor is the ratio of segment lengths:
DE/AB = 8/4 = 2
Triangle DEF is dilated by a factor of 2 (eliminates B).
TranslationTriangle DEF is oriented the same way as triangle ABC, so there is no reflection involved (eliminates A). As we noted, segment DE is 7 units to the right of segment AB, so a translation of x ⇒ x+7 is involved.
SequenceThe translation must occur after the dilation about the origin (eliminates C). If it were to occur first, the translation would be multiplied by the scale factor, so that DE would end up at x=14.
The required sequence of transformations is ...
D. A dilation by a scale factor of 2, centered at the origin, followed by the translation (x, y) ⇒ (x+7, y).

Today, you want to sell a R1 000 par value zero coupon bond you own. The bond matures in five years. How much will you receive for your bond, if the market yield to maturity is currently 5,33%? 10
With a market yield to maturity of 5.33%, the amount that would be received for a R 1,000 par value zero coupon bond that matures in five years, but sold today will be R747.26.
Price calculation for coupon bondsTo calculate the price you will receive for your zero coupon bond, we can use the formula:
P = F / (1 + r)^n
where:
P is the priceF is the par value (face value) of the bondr is the yield to maturity as a decimaln is the number of years to maturity.In this case, the par value is R1,000, the yield to maturity is 5.33%, or 0.0533 as a decimal, and the number of years to maturity is 5.
P = 1000 / (1 + 0.0533)^5P ≈ R747.26Therefore, you can expect to receive approximately R747.26 for your R1,000 par value zero coupon bond when the market yield to maturity is 5.33%.

Which expression is equivalent to 3w-4-w-93w−4−w−9?
A 2w-13
b 4w - 13
c 2w + 5
d -w - 13
Answer: A
Step-by-step explanation:
To simplify 3w-4-w-9, we need to combine the like terms (terms that have the same variable and exponent).
3w - w = 2w
-4 - (-9) = -4 + 9 = 5
So,
3w - 4 - w - 9 = 2w - 13
Therefore, the expression 3w-4-w-9 is equivalent to 2w-13, which is option A.

The cord will begin to stretch after approximately 1.46 seconds.
How to solve for when the stretch startsh(t) = -16t^2 + V0t + h0
149 = h0 - h(t)
Substituting h0 = 241 and h(t) = -16t^2 + V0t into this equation, we get:
149 = 241 - (-16t^2 + V0t)
we get:
16t^2 - V0t - 92 = 0
4(16)(-92) / (2(16)
t = sqrt(1856) / 32

Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed.
The 99% confidence interval for the population proportion p is (0.776, 0.824).
To find the 99% confidence interval for a proportion, we can use the formula:
CI = p^ ± z*(SE)
where p^ is the sample proportion, SE is the standard error, and z is the critical value from the standard normal distribution corresponding to the level of confidence.
For a 99% confidence interval, the critical value z is 2.576.
Substituting the given values into the formula, we have:
CI = 0.80 ± 2.576*(0.03/√200)
Simplifying this expression, we have:
CI = 0.80 ± 0.024
This means that we are 99% confident that the true population proportion falls between 0.776 and 0.824. We can interpret this interval as a range of plausible values for the population proportion, based on the sample data.
