X to the third plus x minus 7 equals -3 square root of x - 1
Ugo [173]

Answer:

  x ≈ 1.5004

Step-by-step explanation:

We suppose your equation is ...

  x^3+x-7=-3\sqrt{x-1}

Squaring both sides and subtracting the right side gives ...

  x^6 +2x^4 -14x^3 +x^2 -23x +58 = 0

This 6th-degree equation has two positive real roots, near x=1.5, and x=2. The root at x=2 is extraneous. The one near x=1.5 is irrational.

THREE FRIENDS WENT ON A TRIP TO THE STRIP OF LAS VEGAS. THE RATES FOR ROOMS IN THE SUMMER ARE USUALLY PRETTY INEXPENSIVE. THE TH
zhuklara [117]

Answer:

$1 is a missing due to the addition of unrelated amounts.

$(20 - 1)×3 + $2

Can never be equal to

$20 × 3

Step-by-step explanation:

The statement in a nut-shell is

- The three friends paid $20 each initially, to make $60.

- $1 each was returned to them, so that they reduced the expenses, and paid $19 each, to make $57.

- They tipped a man $2.

WHY IS $57 + $2 ≠ $60?

That was so, because the amounts that were added weren't related.

If their total spending was what they wanted to calculate, it should have included the amount in the receipt of $55 payment received from the hotel.

The right calculation should have been:

$55 payment to the hotel

+

$3 change the three friends received ($1 each)

+

$2 tip they gave.

=

$60

How can the indicated logarithm be found? Without a calculator❓
e-lub [12.9K]

I guess you're supposed to write the expression on the right in terms of A,B,C.

18. Notice that 729=9^3, so

\log_8729=\log_89^3=3\log_89=3B

20. Notice that \dfrac{14}3=\dfrac{42}9=\dfrac{6\times7}9, so

\log_8\dfrac{14}3=\log_8\dfrac{6\times7}9=\log_86+\log_87-\log_89=A+C-B
