Now, For a function: y = 5ˣ
Range is,
⇒ ( 0 , + ∞ )
And, we have:
y = 5ˣ + 2 ,
which is translated 2 units up.
So, the range is ( 2, + ∞ ).

Answers
To find the minimum score required for an A grade, we need to determine the cutoff point that corresponds to the top 13% of scores.
Given that the scores on the test are normally distributed with a mean of 69.5 and a standard deviation of 9.5, we can use the standard normal distribution to calculate the cutoff point. Using a standard normal distribution table or a statistical calculator, we find that the z-score corresponding to the top 13% is approximately 1.04. To find the corresponding raw score, we can use the formula:
x = μ + (z * σ)
where x is the raw score, μ is the mean, z is the z-score, and σ is the standard deviation. Plugging in the values, we have:
x = 69.5 + (1.04 * 9.5) ≈ 79.58
Rounding this to the nearest whole number, the minimum score required for an A grade would be 80. Therefore, a student would need to score at least 80 on the test to achieve an A grade according to the professor's grading scheme.

A caterer charges a flat fee of $345 in addition
to $45 per person to serve food at a family
reunion.
Write an equation to represent the total cost of
hiring the caterer and the number of people
attending the family reunion?
Answers
Answer: y = 45x + 345
Step-by-step explanation:
So y is the total cost of hiring the caterer and the number of people attending the family reunion.x represents how many people attend. It is $45 per person, so it would be 45 times the number of people attending, or 45x.345 is the extra amount that is added on and must be paid.So...the equation is y = 45x + 345.Hope this helps!!! :)

a pilot is plying over a straight highway. He determines the angles of depression to two mileposts to be 32 degrees and 56 degrees. The pilot is flying at an altitude of 25,00ft. Find the distance between the two points
Answers
The distance between the two points, we can use the trigonometric equation distance = altitude/tan(angle of depression). Using this equation, we can calculate the distance to be approximately 6,665.93 ft.
Pilot is at point A. The angles of depression to mileposts B and C are 32 degrees and 56 degrees, respectively. We are asked to find the distance between B and C.
Let AB = x, BC = y, and AD = CD = h = 25,000 ft.
tan(32°) = h/AB
tan(56°) = h/AC = h/(AB + BC)
We can use the first equation to solve for AB:
AB = h/tan(32°) = 25,000/tan(32°) ≈ 44,908.55 ft
We can use the second equation to solve for AC:
tan(56°) = h/(AB + BC)
tan(56°) = 25,000/(AB + BC)
AB + BC = 25,000/tan(56°)
BC = 25,000/tan(56°) - AB ≈ 38,242.62 ft
Therefore, the distance between the two mileposts is:
BC ≈ 38,242.62 - 44,908.55 ≈ 6,665.93 ft
So the distance between the two mileposts is approximately 6,665.93 ft.

How do you find the initial guess in bisection method?
Answers
The bisection method is a numerical algorithm used for finding roots of a function. This explanation will discuss the process of determining the initial guess in the bisection method.
In the bisection method, the initial guess serves as the starting point for finding a root of a function within a given interval. The key requirement for the initial guess is that it should bracket the root, meaning that the function must have opposite signs at the endpoints of the interval.
To determine the initial guess, you need to identify an interval [a, b] where the function changes sign. This can be done by analyzing the behavior of the function graphically or by examining its values at different points.
Once you have identified an interval that brackets the root, the midpoint of that interval is chosen as the initial guess. The midpoint is computed as (a + b) / 2.
Selecting the midpoint as the initial guess ensures that the root lies within the interval [a, b]. The bisection method then proceeds by iteratively narrowing down the interval until the desired level of accuracy is achieved.
It's important to note that the success of the bisection method depends on choosing a suitable initial guess that satisfies the bracketing condition, leading to a reliable and efficient convergence towards the root.

determine whether the matrix is invertible [2 9 1 14]
A. Yes B. No
Answers
The matrix \(\left[\begin{array}{rr}2 & 9 \\1 & 14\end{array}\right]\) is invertible. Therefore, option A. is correct.
To determine whether the matrix is invertible, we need to check if it has a non-zero determinant.
The given matrix is \(\left[\begin{array}{rr}2 & 9 \\1 & 14\end{array}\right]\), which represents a 2x2 matrix.
The determinant of a 2x2 matrix is calculated as follows:
determinant = (a * d) - (b * c)
where a, b, c, and d are the elements of the matrix.
In this case:
a = 2
b = 9
c = 1
d = 14
Now, let's calculate the determinant:
determinant = (2 * 14) - (9 * 1) = 28 - 9 = 19
Since the determinant is non-zero (19), the matrix is invertible.
Therefore, the answer is:

Given f(x) = 2x2 – 9x + 2, g(x) = 1 - 6x, and
h(x) = x2 – 4, find the following function:
(h+f)(x)
Answers
Answer:
\((h+f)(x)=3x^2-9x-2\)
Step-by-step explanation:
\(f(x)=2x^2-9x+2\\g(x)=1-6x\\h(x)=x^2-4\)
Looks like g(x) is irrelevant here.
You can expand this like so:
\((h+f)(x)\\h(x)+f(x)\)
And even further:
\((x^2-4)+(2x^2-9x+2)\)
Now, it's just a matter of simplifying.
\(x^2-4+2x^2-9x+2\\\\(x^2+2x^2)+(-9x)+(-4+2)\\\\3x^2-9x-2\)
Therefore:
\((h+f)(x)=3x^2-9x-2\)
