Please help me with the following questions. Thanks in advance!

Mathematics
1 answer:
son4ous [18]3 years ago
4 0

Answer:

Step-by-step explanation:

For #6, first use the rule to "undo" the division.  That rule is subtraction:

log(x^2y^6-z^3)

Now "undo" the multiplication with addition:

log(x^2+y^6-z^3)

The last rule is to pull down the exponent to the front:

log(2x+6y-3z)

For #7, begin by setting each expression equal to x, what we are solving for.

log_{4}18=x

Writing this as an exponent:

4^x=18

Take the natural log of both sides:

ln(4^x)=ln(18)

Following the same rule as above, we can pull the x down front:

x ln(4)= ln(18)

To solve for x, just divide both sides by ln(4) to get that

x = 2.08

Do the same thing for 7b.

log_{\frac{1}{2} }74=x and

\frac{1}{2}^x=74 and

ln(\frac{1}{2})^x=ln(74) and

xln(\frac{1}{2})=ln(74) and divide both sides by ln(1/2) to get that

x = -6.21

What is the volume of a cube with the fraction 6/7 on three sides.
GaryK [48]
Volume cube=side^3
side=6/7
volume=(6/7)^3
remember
(a/b)^c=(a^c)/(b^c)
(6/7)^3=(6^3)/(7^3)=216/343

the volume is 216/343 cubic units

Find the surface area of a pyramid
Sergeeva-Olga [200]

Answer:

88 inches ^2

Step-by-step explanation:

Well find the side of a triangle first.

4*9=26

26/2=18

There are 4 identical triangles

18*4= 72

Now the bottom square

4*4=16

16+72= 88

88 inches ^2

Please answer as fast as possible thanks
svp [43]

The correct answer is the 2nd choice because -1/6 is closer to 0 and the surface of the pool would be considered 0. -4/6 is farther away from 0 so it is less.
