3.374
Step-by-step explanation:


























Hence the correct answer is 3.374
Answer:
9
Step-by-step explanation:
The function's y-intercept is the value for x=0.
h(0) = 0.5(0 +4)² +1
= 0.5(16) +1
= 8 +1
h(0) = 9
The function's y-intercept is 9.
Since y must equal both 3x+2 and x-4, we deduce that 3x+2 and x-4 must equal each other. So, we have

Answer:
a₇ = 2.375
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r =
=
=
= - 
This indicates the sequence is geometric with nth term
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 152 and r = -
, then
= 152
, so
a₇ = 152
= 152 ×
= 2.375
answer:
23 and 32 are not symmetrical primes because they are not prime numbers
