Indicate whether there is exactly one solution, infinitely many solutions, or no solution to the equation shown.
2x - 4 = 2(x - 2)
Answer:
Infinitely many solution
Step-by-step explanation:
Simplify
2x - 4 = 2x - 4
Lets see:
if we put 1:
2 - 4 = 2 - 4
-2 = -2
Now lets try another number : 2
4 - 4 = 4 - 4
0 = 0
So we can say that there is more than one solution
this cancels out single solution and no solution
There are infinitely many solutions to the given algebraic expression 2x - 4 = 2(x - 2).
The algebraic expression is an expression that is composed of variables and their arithmetic operations.
From the given parameters
2x - 4 = 2(x - 2)Open brackets
2x - 4 = 2x - 4Since we are having the same algebraic expression on both sides;
Then, we won't be able to get exactly one solution but an infinite number of solutions.
This is because any number that is being substituted for the value of x will always give a different solution.

evaluate the following expression log^6 8. round your answer to two decimal places
A.0.90
B.1.16
C.2.08
D.0.86
Answer:
B. 1.16
Step-by-step explanation:
Correct!
The following expression [tex]log^6 8[/tex] evaluates to 0.86. So, The correct answer is 0.86.
We can evaluate the expression log^6 8 as follows:
[tex]log^6 8 = log 8 / log 6 = 0.90309...[/tex] which rounds to 0.86 to two decimal places.
Therefore, the correct answer is D.
Logs:
The exponential function's inverse is known as the logarithm, or log. In other terms, a number's logarithm is the power that a different number, b, must be raised to in order to equal that number.
The expression log x = b represents a logarithm and is symbolized by the symbol "log". This implies that b is equivalent to x when raised to the power of log b.
For instance, since 2 raised to the power of 3 is 8, the logarithm of 8 to the base 2 is 3.
Calculus, statistics, computer science, and other branches of mathematics all make use of logarithms. Numerous more practical uses include determining pH levels and decibel levels.

Write the standard equation of the circle with center (-14, -3) that passes through the point (-5,3),
Answer:
[tex](x + 14)^2 + (y + 3)^2 = 117[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In which r is the radius.
Center (-14, -3)
This means that [tex]x_0 = -14, y_0 = -3[/tex]
So
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - (-14))^2 + (y - (-3))^2 = r^2[/tex]
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
Passes through the point (-5,3),
This means that when [tex]x = -5, y = 3[/tex]. We use this to find the radius squared. So
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
[tex](-5 + 14)^2 + (3 + 3)^2 = r^2[/tex]
[tex]r^2 = 117[/tex]
So, the equation of the circle is:
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
[tex](x + 14)^2 + (y + 3)^2 = 117[/tex]

missile is fired on a straight line perpendicular to the flight path of the aircraft so that it will
hit the aircraft at a point P (see the accompanying figure). At the instant the aircraft is 2 mi
from the impact point P the missile is 4 miles from P and flying at 1200 miles per hour. At that instant.

Find the 20th term of the sequence.
1600, 1200, 900, ...
First approach :
The above series can be seen as
1600 , (1600–400) 1200, (1200–300) 900 .
So we see that the values are getting decreased by 400,300 respectively.
Hence the next term in the sequence will be 900–200 = 700.
Other approach could be :
A geometric progression with ratio as 3/4.
1600*(3/4) = 1200
1200*(3/4) = 900
900*(3/4) = 675
Taking the above two approaches in mind,the two possible answers could be 700 or 675

The 20th term of the sequence.
1600, 1200, 900, ..., is 6.76.
What is a geometric sequence?A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding terms. This ratio is regarded as one of the geometric sequence's common ratios.
aₙ=a₁(r)ⁿ⁻¹
Given:
A geometric sequence,
1600, 1200, 900, ...
To find the common ratio:
take the ratio of successive terms
r = The value of the second term / the value of the first term
r = 1200/1600 = 0.75.
The explicit formula of a geometric sequence is,
aₙ=a₁(r)ⁿ⁻¹
aₙ= 1600(0.75)ⁿ⁻¹
a₂₀ = 1600(0.75)¹⁹
a₂₀ = 6.76
Therefore, the 20th term is 6.76.

Answer: 1196 cm³
Step-by-step explanation:
Volume of the rectangular prism: 12 x 20 x 5 = 1200 cm³
Volume of the eraser: 4 x 2 x 0.5 = 4 cm³
Therefore volume not occupied = Rectangular prism volume - eraser volume
1200 - 4 = 1196 cm³
Answer:
1196
Step-by-step explanation:
4 * 2 * 0.5 = 4
12 * 20 * 5 = 1200
1200 - 4 = 1196
what is the approximate diameter of a sphere with a volume 34 cm the third power?
Answer:
Diameter = 4cm________________Step-by-step explanation:
volume = 34cm³
volume = 4/3×π×radius³
34cm³ = 4/3 × 3.14 × radius³
34cm³ = 12.56/3 × radius³
radius³ = 34×3/12.56
radius³ = 8
radius = ³√8
radius = 2cm
diameter = 2×radius
= 2×2
= 4cm
