How can I find the three iterations of 3^(x)= 2^(-x)+4
After factorizing the given equation, we can find the three iterations by putting the consecutive values of x.
The given equation is 3∧x = 2∧(-x) + 4. We can modify it as shown below:
Take logarithm on both the sides
log(3∧x) = log[2∧(-x) + 4]
xlog3 = log[2∧(-x) + 4]
x = log[2∧(-x) + 4] / log3
For the first iteration, put x = 1
x = log[2∧(-1) + 4] / log3
x = log4.5 / log3
x = 0.477
For the second iteration, put x = 2
x = log[2∧(-2) + 4] / log3
x = log4.25 / log3
x = 0.477
For the third iteration, put x = 3
x = log[2∧(-3) + 4] / log3
x = log4.125 / log3
x = 0.477
So, this is how we can find three iterations.

Jaxon is flying a kite, holding his hands a distance of 3.25 feet above the ground and letting all the kite’s strings play out. He measures the angle of elevation from his hand to the kite to be 24∘. If the string from the kite to his hand is 105 feet long, how many feet is the kite above the ground? Round your answer to the nearest tenth of a foot if necessary.
Answer: 46.0 ft
Step-by-step explanation:
[tex]\sin 24^{\circ}=\frac{x}{105}\\\\x=105\sin 24^{\circ}[/tex]
So, the distance above the ground is [tex]105\sin 24^{\circ}+3.25 \approx \boxed{46.0 \text{ ft}}[/tex]
An open rectangular box with a volume of 12 cubic meters has a length that is 5 times the width. Express the surface area of the box as a function of the length of a side of the base, x.
The area of a 2D form is the amount of space within its perimeter. The surface area of the prism is 5x²+(24/5x)+(24/x).
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Let the width of the rectangular box be x. Therefore, the length of the box is 5x. Now, the height of the box can be written as,
Volume of the box = length × width × Height
12 = 5x² × H
H= 12 / 5x²
Further, the surface area of the open box is,
Surface area of the box
[tex]= (5x \times x) + 2(h \times x) + 2(5x \times h)\\\\= (5x^2) + 2(\dfrac{12}{5x^2} \times x) + 2(5x \times \dfrac{12}{5x^2})\\\\\\= 5x^2 + \dfrac{24}{5x} + \dfrac{24}{x}[/tex]
Hence, the surface area of the prism is 5x²+(24/5x)+(24/x).

Find the longer and shorter lengths and hypotenuses
Answer:
Short leg: 9 in
Long leg: 40 in
Hypotenuse: 41 in
Step-by-step explanation:
This problem involves the Pythagorean Theorem, solving a system of equations, and solving a quadratic equation.
The Pythagorean Theorem applies because the question states this is a right triangle. That is one equation.
Two more equations come from descriptive relationships between various sides of the triangle.
Solving the system is done here with the Substitution Method, and solving the quadratic equation is done with factoring and the zero product property. Other methods could be used, but there is a character limit, so we can't dive into every way to solve this.
The Pythagorean TheoremPythagorean Theorem: [tex]a^2+b^2=c^2[/tex] where "c" is the hypotenuse of the right triangle.
"c" must be hypotenuse.
It doesn't matter which of the two legs' lengths is used for "a" & "b". However, because of other parts of the question, we'll need to know which one is which.
The question refers back multiple times to one specific leg (the short one). So, when we refer back to that leg in our equations, we need to make sure we're using the same leg each time.
Keeping track of which leg is which
Let's use "a" for the smaller leg, and "b" for the longer leg.
"c", as always, is the hypotenuse.
Setting up the relationships between the sidesNext, the question gives two statements relating the side lengths of the triangle to each other.
For the first statement, "the length of the longer leg of a right triangle" (that's "b") "...is 13 inches more than three times the length of the shorter leg ("a").
Translating the first sentence into math:
"the length of the longer leg of a right triangle" means "b""...is..." means "=""...13 inches more than..." means " +13 " (start with what's coming next, and then do the adding)"...three times..." means " 3* ""... the length of the shorter leg." means "a".[tex]b=3a+13[/tex]
Similarly from the second statement, we get: [tex]c=3a+14[/tex]
Combining this with the Pythagorean Theorem, we have a system of 3 equations, and 3 unknowns.
[tex]b=3a+13[/tex]
[tex]c=3a+14[/tex]
[tex]a^2+b^2=c^2[/tex]
Solving a system of equationsTo solve a system of equations, there are two main methods:
The substitution methodThe elimination methodEither method can be used, but the substitution method is the most intuitive.
Substitution method
To solve a system with the substitution method, isolate variable in an equation, written in terms of the other variables, and substitute them in to try to get a single equation with a single unknown.
Looking at our system, the first two equations already have "b" and "c" isolated in terms of "a". If we substitute both of these into the third equation, we'll have a single equation in terms of a, and can attempt to solve it.
[tex]b=3a+13[/tex]
[tex]c=3a+14[/tex]
[tex]a^2+b^2=c^2[/tex]
Substituting...
[tex]a^2+(3a+13)^2=(3a+14)^2[/tex]
Rewrite the square binomials as a product...
[tex]a^2+(3a+13)(3a+13)=(3a+14)(3a+14)[/tex]
Apply FOIL (a combination of the distributive property, the commutative properties of multiplication, and combining like terms)...
[tex]a^2+(9a^2+39a+39a+169)=(9a^2+42a+42a+196)\\a^2+(9a^2+78a+169)=(9a^2+84a+196)\\[/tex]
Observe that the equation is a degree-2 polynomial (polynomial with highest power of 2; aka quadratic). Move all terms to one side to get the equation equal to zero in preparation for solving:
[tex]a^2+(9a^2+78a+169)=(9a^2+84a+196)\\a^2+9a^2+78a+169-(9a^2+84a+196)=0\\a^2-6a-27=0\\[/tex]
There are a few ways to solve this, including the quadratic formula. However, factoring the polynomial and using the zero product property is quite efficient here:
Factoring to solve a Quadratic
Since the leading coefficient is 1, we can use the shortcut and find factors of -27 that add to make -6.
-27 has factor pairs of:
1 and -273 and -99 and -327 and -13 and -9 add to make -6, so factoring the polynomial is
[tex]a^2-6a-27=0\\(a+3)(a-9)=0[/tex]
Applying the zero product property...
[tex](a+3)=0[/tex] or [tex](a-9)=0[/tex]
So a=-3 or a=9. Given that this represents a length in a triangle, we discard the negative solution. So a=9.
Finding the other two unknowns
To finish up, substitute the "a" back into the two equations for "b" and "c".
[tex]b=3a+13\\b=3(9)+13\\b=27+13\\b=40[/tex]
[tex]c=3a+14\\c=3(9)+14\\c=27+14\\c=41[/tex]
The original problem set up our measurements in inches, so all three values are measured in inches.
Remember which length was which
"a": short leg
"b": longer leg
"c": hypotenuse
Short leg: 9 in
Long leg: 40 in
Hypotenuse: 41 in.

Find the slope of the curve y=2/x at x=a.
Answer:
We are given:- y=2/xWe need to find the slope of the curve at x=a.Step-by-step explanation:
Solution,
We use the slope formula, setting x=a :
[tex] \displaystyle{{{{ \lim_{h \to0}}}} \frac{ \frac{2}{x + h} - \frac{2}{x} }{h} = \lim_{h \to0} \frac{ \frac{2}{a + h} - \frac{2}{a} }{h} }[/tex]
[tex] \displaystyle{ \lim_{h \to0} \frac{ \frac{2a - 2(a + h)}{a(a + h)} }{h} = \displaystyle{ \lim_{h \to0} \frac{2a - 2(a + h)}{ha(a + h)} }}[/tex]
[tex] \displaystyle{ \lim_{h \to0} \frac{2a - 2a - 2h}{ha(a + h)} = \displaystyle{ \lim_{h \to0} \frac{ - 2h}{ha(a + h)} }}[/tex]
[tex] \displaystyle{ \lim_{h \to0} \frac{ - 2}{a(a + h)} = - \frac{ 2}{ {a}^{2} } }[/tex]
Therefore, The slope of the curve y=2/x at x=a is -2/a^2.
Eve has two more marbles than Solene. Solene has twice as many marbles as Steve. Steve has 7 less marbles than eve. How many marbles do they have in all?
A. 27 B. 20 C. 34 D. 13
Using a system of equations, the total number of marbles that they have is given by:
A. 27.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The variables are given as follows:
Variable x: Eve's marbles.Variable y: Solene's marbles.Variable z: Steve's marbles.Eve has two more marbles than Solene, hence:
x = y + 2.
Solene has twice as many marbles as Steve, hence:
y = 2z -> z = y/2.x = 2z + 2.Steve has 7 less marbles than eve, hence:
z = x - 7.
Hence:
[tex]\frac{y}{2} = x - 7[/tex]
y = 2(x - 7)
y = 2(y + 2 - 7)
y = 2y - 10
y = 10.
Then:
x = y + 2 = 10 + 2 = 12.z = x - 7 = 12 - 7 = 5.Hence the total is given by:
T = 12 + 10 + 5 = 27.

slope of f(x) = -2
slope of g(x) = -7 (slope-intercept form y=mx+b where m is the slope and b is the y-intercept)
