Answer:

156.25

Step-by-step explanation:

$f(x)=4(2.5)^{x-1}\\\\f(5)=4(2.5)^{5-1}\\\\f(5)=4(2.5)^4\\\\f(5)=4(39.0625)\\\\f(5)=156.25$

Therefore, the 5th term of the geometric sequence is 156.25

kkurt [141]

Answer:

$k(-5)=70$

Step-by-step explanation:

The given function is

$k(x)=6x+100$

To find k(-5), we put x=-5 into the given function to get;

$k(-5)=6(-5)+100$

Multiply out to obtain;

$k(-5)=-30+100$

This is the same as;

$k(-5)=100-30$

This simplifies to

$k(-5)=70$

A statement can help you organize the numbers to answer a question about percents

Semenov [28]

Answer:

$50 is 27.02% of $185.

Step-by-step explanation:

Money spent on clothing = $50

Money spent on Groceries = $100

Money spent on Gas = $35

Total money spent = $185

Our question is to find the percentage of total money that is spent on clothing.

Percentage money on clothing = $\frac{Money spent on clothing}{Total money}$ × 100

= $\frac{50}{185}$ × 100

= 27.02% (approx)

Hence, $50 is 27.02% of $185.

Abigail is 8 years older than Cynthia.Twenty years ago Abigail was three times as old as Cynthia.How old is each now?

xz_007 [3.2K]

Let
C=Cynthia's age today
A=Abigail's age today

then
at all times
A=C+8......................(1)
twenty years ago,
A-20=3(C-20)
simplifying
A=3C-40...................(2)

Equate (1) and (2),
C+8=3C-40
8+40=3C-C
C=24
=>
A=32

Check: A-C=8... ok A-20=12 C-20=4 => (A-20)=3(C-20) ...ok

Answer:
Abigail is 32, Cynthia is 24.
