Answer: x = 1
x =(-3-√-15)/4=(-3-i√ 15 )/4= -0.7500-0.9682i
x =(-3+√-15)/4=(-3+i√ 15 )/4= -0.7500+0.9682i
x2 = 0

1) x-1+5[tex]\sqrt{x-1\\}[/tex]+3=0
4) [tex]x^{4}[/tex] -64=0
Answer:
See explanation below
Step-by-step explanation:
Find the value of x in each of the following
1) x-1+5√x-1+3=0
5√x-1 = -x -2
Square both sides
25(x-1) = (-x-2)^2
25(x-1) = x^2+4x + 4
25x-25 = x^2+4x + 4
x^2 +4x + 4 - 25x + 25 = 0
x^2 - 21x + 29 = 0
x = 21±√21²-4(29)/2
x = 21±√441-116/2
x = 21±√325/2
x = 21±18.03/2
x = 21+18.03/2 and 21-18.03/2
x = 19.515 and 1.485
4) x^4-64=0
x^4 = 64
[tex]x = \sqrt[4]{64}[/tex]
x = 2.83

Step-by-step explanation:
IXL
The required, city Fairview has a lower ratio of negative to positive reviews.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
here,
A restaurant critic reviewed restaurants in Oxford and Fairview.
In Oxford, the critic gave 18 negative reviews and 33 positive reviews.
ratio = 18 / 33 = 0.54
In Fairview, 5 of the reviews were negative and 11 were positive reviews.
Ratio = 5 / 11 = 0.45
Thus, the required, the city of Fairview has a lower ratio of negative to positive reviews.

Victoria wants to purchase a skateboard. This weekend, the skateboard she wants is on sale for $140.25, 15% off the original price. Victoria cannot make it to the store this weekend. What price will she pay for the skateboard?
Answer:
$161.29
Step-by-step explanation:

140.25 × (1 + 15%) = 140.25 × (1 + 0.15) = 161.2875
Total profit P is defined as total revenue R minus total cost C, and is given by the function P(x)=R(x)−C(x). Find the total profit P(x) when R(x)=126.98x−0.5x2 and C(x)=3809.40+0.7x2.
Given:
The revenue function is
[tex]R(x)=126.98x-0.5x^2[/tex]
The cost function is
[tex]C(x)=3809.40+0.7x^2[/tex]
To find:
The profit function.
Solution:
We know that, the total profit P is defined as total revenue R minus total cost C.
So, the profit function is
[tex]P(x)=R(x)-C(x)[/tex]
[tex]P(x)=126.98x-0.5x^2-(3809.40+0.7x^2)[/tex]
[tex]P(x)=126.98x-0.5x^2-3809.40-0.7x^2[/tex]
[tex]P(x)=-3682.42-1.2x^2[/tex]
Therefore, the profit function is [tex]P(x)=-3682.42-1.2x^2[/tex].

the turnout for the game is expected to reach 80,000 fans of which 57% expected to drive. An average of three fans come in each vehicle 2000 vehicles park in satellite lots the rest of the vehicles parked in the stadium lot how many vehicles parked in the stadium lot
Answer:
13,200 vehicles
Step-by-step explanation:
57% of 80,000 is 45,600
3 people per car for 2000 vehicles is 6,000
45,600-6,000=39,600
lastly 39,600/3=13,200

Answer:
Approximately 40.37 feet
Step-by-step explanation:
Opposite = 30 feet and the length of the wire (I'll use x to represent it) is the hypotenuse.
sin(48) = 30/x
x = 30/sin(48)
x = 30/0.74
x ≈ 40.37

Answer:
an = 6n - 18
Step-by-step explanation:
a3 = 0, a4 = 6, a5 = 12, a6 = 18, a7 = 24
a3 = a + 2d
a4 = a + 3d
a + 2d = 0 (1)
a + 3d = 6 (2)
Subtract (1) from (2) to eliminate a
3d - 2d = 6 - 0
d = 6
Substitute d = 6 into (1)
a + 2d = 0 (1)
a + 2(6) = 0
a + 12 = 0
a = -12
nth term,an = a + (n - 1)d
= -12 + (n - 1) 6
= -12 + 6n - 6
= 6n - 18
an = 6n - 18
A taxicab charges $1.85 for the first quarter-mile and then $0.25 for every quarter mile after the first. The cost for a 17.5 mile trip is
Answer:
$19.10
Step-by-step explanation:
So since he charges $1.85 for the first quarter mile we can keep that as it is for now. If we add 0.25 4 times to make it $1 that would be a mile. We just have to add $17.25 plus the original $1.85 fee

Answer:
A. 4
Step-by-step explanation:
hypotenuse (h) = 5
base (b) = 3
perpendicular (p) = a = ?
We know
By using Pythagoras theorem
p = √( h² - b²)
a = √( 5² - 3²)
a = √(25 - 9)
a = √ 16
