More un functions Airplane Distance. An airplane is flying at an altitude of 3700 ft. The slanted distance directly to the airport is d feet. Express the horizontal distance h as a function of d
1: The horizontal distance h can be expressed as a function of the slanted distance d.
2:
To understand the relationship between the horizontal distance h and the slanted distance d, we can visualize a right triangle formed by the airplane's altitude, the slanted distance, and the horizontal distance. In this triangle, the altitude acts as the vertical leg, the slanted distance as the hypotenuse, and the horizontal distance as the adjacent leg.
Using the Pythagorean theorem, we can relate the three sides of the triangle: altitude squared plus horizontal distance squared equals slanted distance squared. Mathematically, this can be represented as h² + 3700² = d².
By rearranging the equation and solving for h, we can express the horizontal distance h as a function of the slanted distance d: h = √(d² - 3700²).
This function provides a way to calculate the horizontal distance based on the given slanted distance. By plugging in different values of d, we can obtain the corresponding horizontal distances.

Select the correct answer. The expression f(x) = 12(1. 035)x models the monthly growth of membership in the new drama club at a school. According to the function, what is the monthly growth rate? a. 0. 35% b. 1. 035% c. 3. 5% d. 12%.
The correct option a. 0. 35%, for the monthly growth rate.
Explain the term growth rate?The growth rate of the a value (such as GDP, turnover, earnings, etc.) gauges how much it has changed over time (month, quarter, year). The percentage is a fairly universal way to communicate it.Take the current number and subtract it from the prior value to determine the growth rate. The growth rate is then expressed as a percentage by multiplying the difference even by previous number and dividing by 100.Provided that we have done so;
The definition of the phrase is;
f(x) = 12(1. 035)ˣ .....eq1
As we are aware, the exponential function's general form is:
f(x) = a(1 + r)ˣ ...eq 2
Here, a stands for the starting sum.R stands for the growth rate.Comparing reveals that;
1 + x = 1.035
r = 0.035
r = 0.035 x 1005
x = 3.5%.
Thus, according to the given function, the monthly growth rate is found as 3.5%.

y=4x+7 y=9x+8 substitution
The value of \(x=-\frac{1}{5}\) and \(y=\frac{31}{5}\).
The given equations are \(y=4x+7\) and \(y=9x+8\).
We have to solve these equations using the substitution method.
Substitution Method
In this method we find the value of one variable from one equation using elimination method and then put that value of that variable in other equation. In simple word we substitute value of one variable from one equation to the other equation.
In the given equation the two equation are
\(y=4x+7\dots\dots\dots\)Equation \((1)\)
\(y=9x+8\dots\dots\dots\)Equation \((2)\)
Putting the value of \(y\) from the Equation \((1)\) in the Equation \((2)\)
\(4x+7=9x+8\)
Subtract \(8\) on both side
\(4x+7-8=9x+8-8\)
Simplifying
\(4x-1=9x\)
Subtract \(4x\) on both side
\(4x-1-4x=9x-4x\)
Simplifying
\(-1=5x\)
\(5x=-1\)
Divide by \(5\) on both side
\(\frac{5}{5}x=-\frac{1}{5}\)
\(x=-\frac{1}{5}\)
Now putting the value of \(x\) in equation \((1)\)
\(y=4(-\frac{1}{5})+7\)
Simplifying
\(y=-\frac{4}{5}+7\)
\(y=-\frac{4}{5}+7\times\frac{5}{5}\)
\(y=-\frac{4}{5}+\frac{35}{5}\)
\(y=\frac{-4+35}{5}\)
\(y=\frac{31}{5}\)
Hence, the value of \(x=-\frac{1}{5}\) and \(y=\frac{31}{5}\).

A small town's raffle has 85 entries and 3 gift baskets that three different people could win. What is the probability of winning a gift basket if you have 1 of the entries? [1 point]
Answer: 3 / 85
Step-by-step explanation:
Given the following :
Number of gift basket = 3
Nunber of entries = 85
Probability of winning a gift basket if you have one of the entries :
With one entry, one has a chance of winning one of 3 gift baskets
Hence, the required outcome of one entry = 3
Total possible outcomes = number of entries = 85
P(winning a gift basket with one entry) :
Required outcome / Total possible outcomes
= 3 / 85
Also, it could be calculated thus ;
Probability of one entry from a total of 85;
= 1/ 85.
And one entry has a Chance of winning one of 3 different gift baskets
Hence (1/85 × 3) = 3/85

Find the roots of the function f(x)=x^2+15x-16
Answer:
x = -16 and x = 1
Step-by-step explanation:
"Finding the roots" means solving the equation. We'll set the equation equal to 0 (replace f(x) with zero) and factor.
0 = x^2 + 15x - 16
0 = (x + 16)(x - 1)
This is factored.
Using the Zero Product Property, we separate this into two small equations.
x+16 = 0 and x-1 = 0
Solve these one-step equations.
x = -16 and x = 1
These are the roots (and roots are solutions, are zeros, are x-intercepts) If the question ask for zeros, roots, solutions or x-intercepts, set it equal to 0, factor and solve.

we know that
The linear equation in slope intercept form is equal to
\(y+mx+b\)
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
The slope or unit rate is equal to
\(m=-\dfrac{1}{100} \dfrac{^\circ C}{m}\) ---> is negative because is a decreasing function
The y-intercept or initial value is equal to
\(b=4^\circ C\) ----> value of y when the value of x is equal to zero (sea level)
substitute
\(y=-\dfrac{1}{100} x+4\)
For x=1,100 m
substitute in the linear equation and solve for y
\(y=-\dfrac{1}{100} (1,100)+4\)
\(x=-7^\circ C\)

The statement "If gcd(a,b) ≠ 1 and gcd(b,c) ≠ 1, then gcd(a,c) ≠ 1." is false, and a counterexample is gcd(a) = 2, gcd(b) = 2, gcd(c) = 4. In this case, gcd(a,b) = gcd(b,c) = 2, but gcd(a,c) = 4, which contradicts the statement.
To prove that the given statement "If gcd(a,b) ≠ 1 and gcd(b,c) ≠ 1, then gcd(a,c) ≠ 1." is false we can look at a counterexample:
Let a = 6, b = 4, and c = 9.
gcd(a,b) = gcd(6,4) = 2 (which is not 1)
gcd(b,c) = gcd(4,9) = 1 (which is 1)
Although gcd(a,b) ≠ 1 and gcd(b,c) ≠ 1, gcd(a,c) = gcd(6,9) = 3, which is not equal to 1. This counterexample shows that the statement is false.

2i and 3i are zeros
f(-1)=150
An nth-degree polynomial function with real coefficients satisfying the given conditions and n = 4, 2i and 3i are zeros and f(-1) = 150 can be found as follows:First of all, the complex conjugate of 2i is -2i and that of 3i is -3i. Since all coefficients of the polynomial are real, so their product must also be a factor of the polynomial.
The factor of the polynomial whose zeroes are 2i and -2i is(x - 2i) (x + 2i) = (x^2 + 4).Similarly, the factor of the polynomial whose zeroes are 3i and -3i is(x - 3i) (x + 3i) = (x^2 + 9).Therefore, the nth-degree polynomial function with real coefficients satisfying the given conditions is:f(x) = a (x^2 + 4) (x^2 + 9)Where a is the constant of proportionality.To find the value of a, substitute the value of x as -1 in the equation given in the problem and equate it to 150.
f(-1) = a ((-1)^2 + 4) ((-1)^2 + 9)150 = a (5) (10)a = 150/50a = 3
Hence, the required nth-degree polynomial function with real coefficients satisfying the given conditions is:f(x) = 3 (x^2 + 4) (x^2 + 9) and it has been obtained above.

By answering the given question, we may state that Hence, the first-time interest home buyer's mortgage brokerage fees would be $1,653.45.
what is interest ?Divide the principal by the interest rate, the length of time, and other factors to arrive at simple interest. Simple return = principal + interest + hours is the marketing formula. This method makes it easiest to calculate interest. The most typical technique to figure out interest is as a portion of the principal sum. He will only pay his share of the 100% interest, for example, if he borrows $100 from a friend and agrees to pay it back with 5% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you give it out, you must charge interest. Interest is often determined as an annual percentage of the loan total. The interest on the loan is this percentage.
In order to determine the mortgage brokerage fees, we must first determine 1.05% of the funded amount and then add the $300 flat charge.
The formula for 1.05% of $128,900 is as follows:
1.05/100 x $128,900 = $1,353.45
The following would be the mortgage brokerage fees:
$1,353.45 + $300 = $1,653.45

In mathematics, an Sequence is an enumerated collection of objects in which repetition is allowed and in case order. Like a collection, it contains members (also called elements or items). The number of elements (possibly infinite) is called the length of the array. Unlike sets, the same item can appear multiple times at different positions in the sequence, and unlike sets, order matters. Formally, a sequence can be defined in terms of the natural numbers (positions of elements in the sequence) and the elements at each position.
The concept of series can be generalized as a family of indices, defined in terms of any set of indices.
