What is the value of c in the equation x^15/x^c =x^6

Mathematics
1 answer:
Galina-37 [17]2 years ago
3 0

Step-by-step explanation:

\frac{ {x}^{15} }{ {x}^{c} }  =  { x}^{6} \\  {x}^{15 - c}  =  {x}^{6}

15 - c = 6

15 - 6 = c

9 = c

c = 9

Any help towards finding out Part B and C would be greatly appreciated!
Alika [10]
Part B: I think the relation that has the greater value when x=6 is f(x) = 7x - 15 because:

7(6) - 15 = 27 which is greater than the output of 14.

Part C: the value of x would be 3 because:

f(x) = 7x - 15
6 = 7x - 15
+ 15 +15
21 = 7x
3 = x

Sorry if any of this is wrong.

Which of the following must be true in order for SAND to be in a rhombus? Select all that apply
Ahat [919]

Answer:

Consecutive sides must be congruent.

All interior angle adds up to 360°

Step-by-step explanation:

Rhombus:

1. Sides: all 4 sides are congruent.

Then consecutive sides must be congruent.

2.Diagonals : Diagonals bisect each other at 90°.

So, second option is wrong.

3. Sum of interior angle is 360°.

Solve for x write the exact answer using either base -10 or base-e logarithms
jeka57 [31]

<u>Given</u>:

The given expression is 2^{x+5}=13^{2 x}

We need to determine the value of x using either base - 10 or base - e logarithms.

<u>Value of x:</u>

Let us determine the value of x using the base - e logarithms.

Applying the log rule that if f(x)=g(x) then \ln (f(x))=\ln (g(x))

Thus, we get;

\ln \left(2^{x+5}\right)=\ln \left(13^{2 x}\right)

Applying the log rule, \log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x), we get;

(x+5) \ln (2)=2 x \ln (13)

Expanding, we get;

x \ln (2)+5 \ln (2)=2 x \ln (13)

Subtracting both sides by 5 \ln (2), we get;

x \ln (2)=2 x \ln (13)-5 \ln (2)

Subtracting both sides by 2 x \ln (13), we get;

x \ln (2)-2 x \ln (13)=-5 \ln (2)

Taking out the common term x, we have;

x( \ln (2)-2 \ln (13))=-5 \ln (2)

                          x=\frac{-5 \ln (2)}{\ln (2)-2 \ln (13)}

                          x=\frac{5 \ln (2)}{2 \ln (13)-\ln (2)}

Thus, the value of x is x=\frac{5 \ln (2)}{2 \ln (13)-\ln (2)}
