your teacher is giving you a test worth 100 points that contains 40 questions. there are 2point questions on the test. how many
kykrilka [37]
100 = 2t + 4f 
40= t + f
-----------
get t or f by itself first.

f = 40 - t : Then substitute it back into for f in the other equation
100 = 2t + 4f 
100= 2t +4(40-t) 
100= 2t + 160 - 4t
100 = -2t + 160
-160           -160

<u>-60 </u>= <u>-2t
</u>-2        -2

t = 30 (Then plug this into either equation to solve for f)

Therefore,
t = 30 questions
f = 10 questions

f(5)=12 for a geometric sequence that is defined recursively by the formula f(n)=0.3*f(n-1), where n is an integer and n&gt;0. F
ElenaW [278]

Answer:

f(7) = 1.08

Step-by-step explanation:

Given that:

f(5) = 12

A geometric sequence that is defined recursively by the formula

f(n) = 0.3 \cdot f(n-1)       .....[1 ] where, n is an integer and n> 0.

Substitute n = 6 in [1] we have;

f(6) = 0.3 \cdot f(5)

Using f(5) = 12 we have;

f(6) = 0.3 \cdot 12

⇒f(6) =3.6

We have to find f(7).

Substitute n = 7 in [1] we have;

f(7) = 0.3 \cdot f(6)

Substitute the given values f(6) = 3.6 we have;

f(7) = 0.3 \cdot 3.6

Simplify:

f(7) = 1.08

Therefore, the value of f(7)to the nearest hundredth is, 1.08
