Sean is exploring a coral reef 91 feet below sea level and liz is hiking 91 feet above sea level. Who is hiking farther away from sea level
They are about same distance from sea level.
Sean is exploring a coral reel below level= 91 feet
Liz is hiking above sea level= 91 feet
When, we compare both distance from sea level, both have the sane distance. Although, the distance between both Sean and Liz is 91+91= 182 feet.
When compare the level of both , both are at 91 feet one is below the sea level and another is above the sea level. Hence, both are at the same distance from the sea level.
Hence, the correct answer is both at 91 feet from seal level.

Can someone help me express this as a single fraction, i’m not sure of my answer
Answer:
3x-6/2[tex]\sqrt{x-1[/tex]
Step-by-step explanation:
1. first we have to get the denominator the same, so we multiply by [tex]\sqrt{x-1[/tex] to the first fraction top and bottom which leaves as with
3(x-1)/2[tex]\sqrt{x-1[/tex] - 3/2[tex]\sqrt{x-1[/tex]
- we can expand the numerator of the first fraction which becomes
3x-3/ 2[tex]\sqrt{x-1[/tex] - 3/2[tex]\sqrt{x-1[/tex]
2. we can now subtract te fraction as we have the same denominator this gives us
3x-6/2[tex]\sqrt{x-1[/tex]
3. your final answer would be
3x-6/2[tex]\sqrt{x-1[/tex]
{If the question asked to simplify your answer you would rationalize your answer by multiplying top and bottom by [tex]\sqrt{x-1[/tex] to give you the answer of

Write each equation in exponential form.
log 0.0001=-4
The exponential form of the given equation is 0.0001 = [tex]10^{-4}[/tex]
The exponential function is the inverse of the logarithmic function and vice versa. This means that the logarithm of a given number, say x, is the exponent to which another fixed number that is the base b, must be raised, so as to produce that number x. Mathematically this means,
logₐ x = y
then x = [tex]a^{y}[/tex]
Here, we are given a logarithmic function- log 0.0001 = -4
since no base is given, we always assume it to be 10
thus, the function can be written as- 0.0001 = [tex]10^{-4}[/tex]
Hence, the exponential form of this equation is 0.0001 = [tex]10^{-4}[/tex].

How to find the angle of a triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
In simpler term, a triangle is a kind of polygon that 3 sides and 3 angles.
Therefore, the sum of angles in a triangle is equals to 180 degrees.
Hence, the sum of angles in ΔABC is 180 degrees.
Therefore,
m∠A + m∠B + m∠C = 180°
m∠A = 32.1°
m∠B = 101.7°
m∠C = x

NEED IT ASAP!!!! The length of the string of a pendulum, L, can be determined using the function L(p)=9.8(p/2pie)^2 , where p is the period of the pendulum. The velocity at the bottom of the pendulum can be modeled by the function v(L)=\sqrt{19.6L} .
Which function can be used to find the velocity at the bottom of the pendulum released from the same angle for any period, p?
A function which can be used to determine the velocity V(L(p)) at the bottom of the pendulum released from the same angle for any period, p is V(L(p)) = p/2π√192.08.
What is a function?A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable to an output variable.
Given the following data:
L(p) = 9.8(p/2π)².
V(L) = √19.6L
A function which can be used to determine the velocity V(L(p)) at the bottom of the pendulum released from the same angle for any period, p is given by:
V(L(p)) = √[19.6 × 9.8(p/2π)²]
V(L(p)) = √(19.6 × 9.8) × √(p/2π)²)
V(L(p)) = 192.08 × (p/2π)

Write the expression that represents the total length of each segment shown.
The expressions for the total length of each segment are x + 1, d + 4, and y + 3.
The total length of the segments will be the sum of the part so the segments.
Let's say a line segment AB is divided into two parts x and y then the expression for the length of the segment will be x + y.
Now,
For the first segment,
The two parts are x and 1.
The expression of the total length of the segment is:
x + 1
For the second segment,
The two parts are d and 4.
Then the expression for the total length of the segment is:
d + 4

the height of a triangle is twice its base the area is 144cm³ find the base
Answer:
Base = 12cm
Height = 24cm
Step-by-step explanation:
Hello glittersplanet,
The formula for the area of a triangle is A = 1/2 b * h where A equals the area, b equals the base, and h equals the height. You are given the area in this problem.
Let the following conditions apply:
Base = x
Height 2x <-------Problem states the height is twice its base, correct?
Therefore:
A = 1/2 b*h
144 = 1/2 (x)(2x)
Simplify by removing the fraction by multiplying through by 1/2 and you are left with x^2 correct? Therefore:
144 = x^2
x = √144
x = 12
Therefore, base = x = 12 while height = 2x = 2(12) = 24
x = √144
Footing-x=12
Height-x2=24

3.The temperature in degrees Fahrenheit that is equivalent to a temperature in degrees Celsius is given by the function F(C)=95C+32. Find the temperature in degrees Fahrenheit that corresponds to a temperature of 15 degrees Celsius.
4.A ball is thrown in the air and its height after t seconds is given by the following function: h(t)=-16t2+32tHow high is the ball after 2 seconds?
1. The domain of the function in interval g(x) = 13x-15/x+4
Domain: (−∞,0)∪(0,∞),{x|x≠0
Range: (−∞,∞),{y|y∈R}
2. The domain of the function in interval y=x2-10x+2
Domain: (−∞,∞) {x|x∈R}
Range: (−23,∞),{y|y≥-23}
3. By rearranging the equation so that C is in terms of F, you may determine the inverse:
F= 5/9C+32
32 is deducted from both sides.
F−32= 5/9C
Add five to both sides:
5(F−32)=9C
multiply both sides by 9.
C= 5/9(F−32)
C=− 25/9
−2.78C o 2.dp
The inverse is, in fact, a one-to-one function.
4. We are looking for the height at t=0 in order to determine the beginning height. To do this, replace t with 0 and find h.
h(t)= -16t2 + 32t + 24
h(0) = -16(0)2 + 32(0) + 24
h(0) = 24
24 feet is the initial height
The constant in the equation often represents height. 24 in this instance.
The coefficient of x, in this case 32, represents the beginning velocity.
32 feet per second is the beginning velocity.

e is the constant growth rate that all processes that are growing continuously share. With e, you may compare a simple growth rate—where all change occurs at the end of the year—with a compound, continuous growth rate, where growth occurs once per nanosecond or quicker.Let the principle sum be P

The inverse of the function f(x)=√x+6 will be x²-12x+36.
Inverse function-A function that can reverse into another function is known as an inverse function or anti-function.
The given function is,
f(x)=√x+6
As we know inverse of the function is shown as,
y = f(x)
y=√x+6
For inverse function, we have to replace the variable's place value,
x=√y+6
√y=x-6
Squaring both sides,
(√y)²=(x-6)²
y=x²+36-12x
Hence,the inverse of the function f(x)=√x+6 will be x²-12x+36.
