Answer:
7 or -7
Step-by-step explanation:
the question is asking for x to to the second power which is x squared or x^2
so setting x^2=49
square root both sides of the equation so that x is by itself and the other side is just ±√(49). which ±√49 is just 7 or -7

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
Um- here ya go
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.

a constant speed of 600 miles per hour. An antiaircraft
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.

The exterior angles of any polygon always add up to 360, so:

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.

The product of twice a number and five is the same as the difference of nine times the number and 3/4. Find the difference
Answer:
I think the answer is -3/4
Step-by-step explanation:
Let x = a number
(2x)(5) = 9x - (3/4)
10x = 9x - (3/4)
Subtract 9x on both sides of equation.
x = -3/4

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

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.
