Answer:

10152

Step-by-step explanation:

Common difference:

18-9=9

27-18=9

d=9

Explicit formula:

an = a1 +(n-1)d

a47 = 9+ (46)(9)

a47 = 423

Find sum: Sn = n(a1+an)/2

47(9+423)/2

47(423)/2 = 20304/2 = 10152

How many cubic units is a box that is 3 units high, 3 units wide, and 2 units deep?
vivado [14]

Answer:

volume of the box is 18 cubic units.

Step-by-step explanation:

A box that measures  3 units high, 3 units wide, and 2 units deep

hieght of the box= 3

lenght of the box is 2  and width of the box is 3

To find cubic units we determine the volume of the box

volume = length times width times height

Volume of the box= 2 \cdot 3 \cdot 3= 18

the volume of the box is 18 cubic units.

Which of these equations are linear functions that go
serious [3.7K]

Answer:

I don't think the answer exist

Step-by-step explanation:

for y=6x

when y=0, x=0 and when x=0, y=0

hence, (x,y)=(0,0)

for y=x+6

when y=0, x+6=0, x=-6 and when x=0, y=6

hence (x,y) = (-6,6)

for y=x^2+6

when x=0, y=6 and when y=0,

x^2+6=0

subtracting 6 from both sides

x^2=-6

take the square root of both sides and get

x=+ or -sqrt(-6)= + or - (2.45i)

i.e. x=+2.45i or x=-2.45i these are complex roots anyway, and its out of point.

for y=2x+6

when x=0, y=6 and when y=0,

2x+6=0,

2x=-6,

x=-3

the coordinates give (x,y)=(-3,6)

conclude....

Let log_b 4= G and log_b9= S. Write the expression in terms of G and S
Liono4ka [1.6K]

S-G is the expression in terms of G and S

<h3>What is the expression in terms of G and S?</h3>

Given: log_b 4 = G, log_b9 = S and log_b 9/4

To write log_b 9/4 in terms of G and S, we need to understand logarithm division rule, which states that:

When you divide two values with the same base is to subtract the exponents. Simply, the rule for division is to subtract the logarithms i.e.

logₓ (a/c) = logₓa - logₓc

Thus,  log_b (9/4) = log_b 9 - log_b 4  = S - G  

(Note: log_b 4 = G and log_b9= S)

Therefore, the expression log_b (9/4) in terms of G and S is S-G

What is the difference between the smallest six digit number and the greatest four digit number
drek231 [11]
The smallest (whole number ) 6 digit number is 1,000,000
The greatest (whole number 4 digit number is 9,999
The difference between them means to subtract the four digit number from the 6 digit number.
The difference is 990,001

I would not consider 000001 to be a 6 digit number (in case this is supposed to be a trick question.)
