Mathematics
1 answer:
noname [10]3 years ago
8 0

Answer:

C

Step-by-step explanation:

The terms form a geometric sequence with common ratio r

r = \frac{a_{2} }{a_{1} } = \frac{a_{3} }{a_{2} } = ......

r = \frac{108}{-81} = \frac{-144}{108} = - \frac{4}{3}

The n th term formula of a geometric sequence is

a_{n} = a (r)^{n-1} ← a is the first term

here a = - 81, hence

f(x) = - 81(-\frac{4}{3}) ^{x-1} → C

To rent a uhal truck for the day, it cost 20 dollars per day plus 1 dollar for every mile driven Write an algebraic expression t
valkas [14]

Answer:

The equation is R = 20d + m(1)

Where R is the rental amount in dollars, d is the number of days and m is the number of miles driven

R for 3 days and 1000 miles is $1,060

Step-by-step explanation:

To properly represent the algebraic expression, we need to assign some variables.

Now, let the rental amount be R, the number of miles driven be m and the number of days rented for is d

Thus, we can say that:

R = 20d+ m(1)

Where R is rental amount, m is the number of miles driven and d is the number of days for which the truck was driven.

Now we are asked to calculate rental amount for 3 days and 1000 miles.

R = 20d + m(1)

R = 20(3) + 1000(1)

R = 60 + 1000

R = $1,060

What is the surface area of the rectangular prism below 7, 7, 14
Julli [10]

Answer:

Surface Area   A = 490 cm²

Step-by-step explanation:

Surface area of a prism A = 2(w l +h l + h w)

where l = length

        w = width

        h = height

l = 7 cm; w = 7 cm ; h = 14 cm

Surface Area = 2 { ( 7 × 7) + ( 14 × 7) + ( 14 × 7)}

            A = 2 { 49 + 98 + 98}

            A = 2 × 245

            A = 490 cm²

Last one: 1/5 • 950
Because it would be 20/100 which equals 1/5 simplifies, then you take that and multiply it by the number
