Solve. Check for extraneous solutions. x¹/₂-(x-5)¹/₂=2
Answers
No extraneous solution to the equation:
The equation is:
[tex]x^{1/2}[/tex] - [tex](x- 5)^{1/2}[/tex] = 2
To know whether the equation has an extraneous solution first we need to find the value of x.
[tex]x^{1/2}[/tex] - 2 = [tex](x - 5)^{1/2}[/tex]
[tex]x^{1/2} - 2[/tex] = [tex](x - 5)^{1/2}[/tex]
Now squaring both sides of the equation we have:
[tex](x^{1/2} - 2)^{2}[/tex] = x - 5
x - 4[tex]x^{1/2}[/tex] + 4 = x -5
[tex]x^{1/2}[/tex] = -9/4
x = 81/16
Now we have to put the value of x in the equation.
[tex](81/16)^{1/2}[/tex] - [tex](81/16 - 5)^{1/2}[/tex] =2
9/4 - 1/4 =2
8/4 = 2
2 =2

m∠ABC=(6x+8)° and m∠DEF=(12x−8)°. If ∠ABC and ∠DEF are supplementary, what is the measure of each angle?
Answers
Given that ∠ABC and ∠DEF are supplementary, the numerical value of ∠ABC and ∠DEF are 68° and 112° respectively.
What is the measure of each angle?Supplementary angles are angles that sum up to 180 degrees.
Given the data in the question;
∠ABC and ∠DEF are supplementaryMeasure of ∠ABC = (6x + 8)°Measure of ∠DEF = (12x − 8)°Since ∠ABC and ∠DEF are supplementary, it means they sum up to 180 degrees.
Measure of ∠ABC + Measure of ∠DEF = 180°
Plug in the given values and solve for x
(6x + 8) + (12x − 8) = 180
6x + 8 + 12x − 8 = 180
6x + 12x + 8 - 8 = 180
18x + 0 = 180
18x = 180
x = 180/18
x = 10
Now, the numerical measure of each angle will be;
Measure of ∠ABC = (6x + 8)° = 6(10) + 8 = 60 + 8 = 68°
Measure of ∠DEF = (12x − 8)° = 12(10) - 8 = 120 - 8 = 112°

A frog is about to hop from the bank of a creek. The path of the jump can be modeled
by the equation h(x) = -x² + 4x + 1, where h(x) is the frog's height above the water and
x is the number of seconds since the frog jumped. A fly is cruising at a height of 5 feet
above the water. Is it possible for the frog to catch the fly, given the equation of the
frog's jump?
Answers
Answer:
The frog will catch the fly after 2 seconds of his jump.
Step-by-step explanation:
It is given that a frog is about to hop from the bank of a creek. The path of the jump can be modeled by the equation h(x) = -x² + 4x + 1, where h(x) is the frog's height above the water and x is the number of seconds since the frog jumped and a fly is cruising at a height of 5 feet above the water.
Now, let us assume that the frog catches the fly that is cruising at a height of 5 feet above the water;
=> h = 5 feet
So, let us put the value of h = 5 for time x;
=> h(x) = -x² + 4x + 1
=> 5 = -x² + 4x + 1
=> x² - 4x - 1 + 5 = 0
=> x² - 4x + 4 = 0
Now, on solving the above equation we get;
=> x² - 4x + 4 = 0
=> x² - (2 + 2)x + 4 = 0
=> x² - 2x - 2x + 4 = 0
=> x (x - 2) - 2 (x - 2) = 0
=> (x - 2) (x - 2) = 0
On comparing and solving for the value of x we get;
=> (x - 2) = 0
=> x = 2
and
=> (x - 2) = 0
=> x = 2
Therefore, the frog will catch the fly after 2 seconds of his jump.

Answers
Charlotte traveled in 414.44 feet during the time when she looks down at her phone and takes her eyes off the road for 4.06 s.
The first step is to convert miles per hour to feet per second.
(69.6 mi/hr)* (5280 feet/mi)*(1 hr/3600 sec) = 102.08 feet/sec
We know that,
Speed = [tex]\frac{Distance}{Time}[/tex]
Here, we have given,
Time = 4.06 s
Speed (feet/sec) = 102.08 feet/sec
We need to find, the distance charlotte traveled in feet during the time when she looks down at her phone and takes her eyes off the road for 4.06 s.
Putting the values in the formula, we get
Distance = Speed x Time
= 102.08 x 4.06
= 414.44 Feet

x = 13/2 is not an extraneous solution.

Adding 3 on both the sides of the equation, we get
[tex](2x+3)^{3/4}[/tex] - 3 + 3= 5 + 3
[tex](2x+3)^{3/4}[/tex] = 8
On the right hand side of the equation, 8 can also be written as

Taking power 4/3 on both the side of the equation, we get

2x + 3 = 16
2x = 13
x = 13/2
Check for extraneous solution and putting x = 13/2 in the original equation, we get
[tex](2(13/2) + 3)^{3/4}[/tex] - 3 = 5
[tex]16^{3/4}[/tex] - 3 = 5
