Answer:

Step-by-step explanation:

5:4:3 = x:y:2

4:3 = y:2                 Cross multiply

3y = 8                     Divide by 3

y = 8/3 = 2.66'

5/x = 3/2

3x = 10                   Divide by 3

x = 10/3

x = 3.33

Length of the wood = 2.66 + 3.33 + 2

Length of the wood = 8 feet

Find the sum of the first 30 terms of the sequence. a_(n)=4n+1
oksian1 [2.3K]
We know that
a(n)=4n+1
To find the sum of the first n<span> terms of an arithmetic series
use the formula
</span><span><span>Sn</span>=<span>n(<span>a1</span> + <span>an</span>)/2
</span></span>a1--------------> is the first term
an--------------> is the last term
n--------------- > <span>is the number of terms
</span>we have that
a1------------> 4*(1)+1=5
a30----------> 4*(30)+1=121
n------------- > 30
S30=30*(5 + 121)/2=1890

the answer is 1890

Can anyone help please????
Nesterboy [21]

Answer:

Option A. (f_of^{-1})(-2)=-2

Step-by-step explanation:

Point to remember while solving the question of function,

(f_of^{-1})(x)=x

Here, 'f' is the parent function and f^{-1} is the inverse of the function 'f'.

So for the given function,

f(x) = 2x - 2

(f_of^{-1})(x)=x

For x = -2

(f_of^{-1})(-2)=(-2)

Therefore, Option A will be the correct answer.
