Answer:

The next number is $4$

Step-by-step explanation:

we have

$256, 196, 144, 100, 64, 36, 16,...x$

we know that

$256-196=60$

$196-144=52=60-8$

$144-100=44=52-8$

$100-64=36=44-8$

$64-36=28=36-8$

$36-16=20=28-8$

therefore

The next number is equal to

$16-x=20-8$ ------> solve for x

$16-x=12$

$x=16-12=4$

Doug purchased land for $8,000 in 1995. The year value of the land depreciated by 4% each year thereafter. Use an exponential fu

Marta_Voda [28]

Answer:

Option C. $6,012

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{t}$

where

V is the the depreciated value

P is the original value

r is the rate of depreciation in decimal

t is Number of Time Periods

in this problem we have

t = 7 years

P = $8,000

r = 0.04

substitute in the formula above

$V = 8,000(1-0.04)^{7} = 6,012$

Hope this helps :)

The table shows data gathered by an environmental agency about the decreasing depth of a lake during the first few months of a d

EastWind [94]

(0,346)(2,344.8)
slope = (344.8 - 346) / (2 - 0) = -1.2 / 2 = -0.6

y = mx + b
slope(m) = -0.6
use either of ur points (0,346)...x = 0 and y = 346
now we sub and find b, the y int
346 = -0.6(0) + b
346 = b

so ur equation is : y = -0.6x + 346

after 4 weeks....x = 4
y = -0.6(4) + 346
y = -2.4 + 346
y = 343.6 <=== after 4 weeks it will be 343.6

Mr. Shamir employs two part-time typists, Inna and Jim, for his typing needs. Inna charges $15 an hour and can type 6 pages an h

coldgirl [10]

Answer:

The minimum cost would be 480$ when Inna works for 8 hours and Jim works for 20 hours.

Step-by-step explanation:

We are given the following information in the question:

Charges for 1 hour for Inna = $15

Number of pages typed by Inna in 1 hour = 6

Charges for 1 hour for Jim = $18

Number of pages typed by Jim in 1 hour = 8

Let x be the number of hours Inna work and let y be the number of hours Jim work.

Total cost = $15x + 18y$

We have to minimize this cost.

Then, we can write the following inequalities:

$6x + 8y \geq 208\\x \geq 8\\y \geq 8\\$

The corner points as evaluated from graph are: (8,20) and (24,8)

C(8,20) = 480$

C(24,8) = 504$

Hence, the minimum cost would be 480$ when Inna works for 8 hours and Jim works for 20 hours.

The attached image shows the graph.

Which is equivalent toStartRoot 10 EndRoot Superscript three-fourths x ?

DENIUS [597]

Answer:

I THINK its the last one (8 root 10 to the power of 3x)

Step-by-step explanation:

A square root is the same thing as raising something to the 1/2. So the expression we have is (10^1/2)^3/4x.

Due to exponent rules we can multiply to get

10^3/8x which is the same thing as 10^3x/8

The 8 goes to the root and the 3x becomes the exponent
