Answer:
x = 9[tex]\sqrt{10}[/tex]
Step-by-step explanation:
According to Euclidian theorem :
x^2 = 27*(27+3)
x^2 = 27*30 do the multiplication
x^2 = 810 find the root for both sides
x = 9[tex]\sqrt{10}[/tex]

A number is first increased by 20 and then doubled. The result is 2 less than 5 times the number
a.2(x+20)=5x-2
b.20(x+2)= -2x+5
c.2(x+20)=2x-5
d.2(x-20)=5x+2
Answer:
a.2(x+20)=5x-2
Determine whether the following statement is true or false.
If the base of a logarithm is not written, it is assumed to be 2. *
...
Choose the correct answer below.
O A. The statement is false because if the base of a logarithm is not written, it is assumed to be 1.
OB. The statement is true because if the base of a logarithm is not written, it is assumed to be 2.
O C. The statement is false because if the base of a logarithm is not written, it is assumed to be 10.
OD. The statement is false because if the base of a logarithm is not written, it is assumed to be e.
Answer:
D, but careful on conventions
Step-by-step explanation:
Honestly, it's a matter of conventions. Either C or D, then it's a matter on what whoever wrote the book likes and how he got taught. For example, for me, [tex]log_{10} x = Log x =[/tex], please note the capital L, and [tex]log_e x = ln x[/tex], in order to avoid any confusion - if someone has a terrible handwriting and their capital and small Ls look too similar.

Answer:
x = 0 , -2 , 1 +i√3 ; 1 - i√3
Step-by-step explanation:
2x⁴ + 16x = 0
2x(x³ + 8) = 0
2x(x³ + 2³) = 0
2x (x + 2)(x² -2x + 2²) = 0 {a³ + b³ = (a + b)*(a² -ab +b²}
2x = 0
x = 0
x + 2 = 0
x = -2
x² - 2x + 4 = 0
a = 1 ; b = -2 and c = 4
D = b² - 4ac = (-2)² - 4*1*4= 4 - 16 = -12
[tex]\sqrt{D} = \sqrt{-12}=\sqrt{2*2*3i^{2}}=2i\sqrt{3}[/tex]
root = (-b ± √D)/2a
= (-(-2) ± 2i√3)/2*1
= (2 ± 2i√2)/2
[tex]= \dfrac{2(1 + i\sqrt{3})}{2} \ ; \dfrac{2(1+i\sqrt{3})}{2}\\\\\\= 1 + i\sqrt{3} \ ; \ 1 - i\sqrt{3}[/tex]

An airplane starts to descend from an altitude over 30,000 feet at what rate is the airplane descending?
Answer:
20,000 feet
Step-by-step explanation:
Based on the initial altitude and the rate that the plane is descending, the relevant equation is = 30,000 - 2,000x. The altitude after 5 minutes is 20,000 feet above sea level.
The plane begins at 30,000 feet above ground and is descending at 2,000 feet per minute. The relevant equation after x minutes is:
= Initial altitude - (Descent in feet per minute x Number of minutes)
Plugging in the values gives:
= 30,000 - (2,000 × x)
= 30,000 - 2,000x

Please help with my portfolio question. I have to select the slope per equation
Try this option, all the details are in the attachment.
Answer:
like 1 - y=-5x + 10
line 2 - y=2x + 4
line 3 - y=4x + 3
line 4 - y=8
Step-by-step explanation:
y = mx + b means y equals the slope times x, plus the y intercept, in this case they all had different y intercepts so you just had to look and where the line touches the y axis

Domain (value of x) is any real value except x=13 or x=−25
The domain is the value of x in the function.
Here the denominator must not be zero.
What is the domain?
The domain of a function is the set of inputs accepted by the function.
6x^2+13x−5≠0
or 6x^2+15x−2x−5≠0
or 3x(2x+5)−1(2x+5)≠0
or (3x−1)(2x+5)≠0
or x≠13 and x≠−52
∴Domain (value of x) is any real value except x=13 or x=−25.

For the function f(x)=−8x2+6x−6, find f(−1)
Answer:
Step-by-step explanation:
f(x) = -8x² + 6x - 6
f(-1) = -8(-1)² + 6(-1) - 6
f(-1) = -8(1) + 6(-1) - 6
f(-1) = -8 - 6 - 6
f(-1) = - 20
