Answer:

$log_2(8)= c$

Step-by-step explanation:

logarithmic equation is equivalent to the exponential equation below 2^c = 8

To get exponential form in to log form , we use property

$b^x = a$ is written as $log_b(a)= x$

we use the above property to convert the gien exponential equation in to logarithmic equation

$2^c = 8$ is written as $log_2(8)= c$

#7. What are the values/ how do I do it

Tasya [4]

Answer:

x =2

SK = 21

KY = 13

SY = 34

Step-by-step explanation:

we can see from the picture the following:

SK + KY = SY equation 1

SK=13x-5 equation 2

KY = 2x+9 equation 3

SY = 36-x equation 4

using equation 2, equation 3 and equation 4 in equation 1 we have:

13x - 5 + 2x + 9 = 36-x

15x +4 = 36 - x

15x +x = 36-4

16x = 32

x = 32/16

x= 2

using x as 2 we evaluate it in equation 2, equation 3 and equation 4:

SK=13(2)-5 = 21

KY= 2(2) +9 = 13

SY = 36-2 = 34

Write the linear equation that gives the rule for this table.

MAVERICK [17]

Answer:

The linear equation that gives the rule for this table will be:

y=x+25

Step-by-step explanation:

Taking two points from the table

(2, 27)

(3, 28)

Finding the slope between two points

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(2,\:27\right),\:\left(x_2,\:y_2\right)=\left(3,\:28\right)$

$m=\frac{28-27}{3-2}$

$m=1$

We know the slope-intercept form of linear equation is

$y=mx+b$

where m is the slope and b is the y-intercept

substituting the point (2, 27) and m=1 in the slope-intercept form to determine the y-intercept 'b'

$y=mx+b$

27 = 1(2)+b

27-2 = b

b = 25

Now, substituting m=1 and b=25 in the slope-intercept form to determine the linear equation

y=mx+b

y=1(x)+25

y=x+25

Thus, the linear equation that gives the rule for this table will be:

y=x+25

The post office is now calculating the volume of packages to determine the shipping cost. If a box measure 8 1/2 inches long, 5

sladkih [1.3K]

Answer:
volume of box = 312.375 in²

Explanation:
The volume of a rectangular box can be measured as follows:
volume = length* width * height

From the givens we have:
length = 8.5 in
width = 5.25 in
height = 7 in

Substitute with the givens in the above equation to get the volume as follows:
volume = length * width * height
volume = 8.5 * 5.25 * 7
volume = 312.375 in²

Hope this helps :)
