3 as in 3 layers of skin is that what you were talking about hope this helps plus the 1 layers is epidermous 2 is dermis and 3rd is tissue
False! It is 5 × 10⁷.
50 million is 50 000 000.
50 000 000 = 5 × 10 000 000
Count number of zeros - it is your exponent:
in 100, there are 2 zeros, so: 100 = 10²
in 1000, there are 3 zeros, so: 1000 = 10³
in 10 000 000, there are 7 zerose, so 10 000 000 = 10⁷
50 000 000 = 5 × 10 000 000 = 5 × 10⁷
Notice that the sequence has a common ratio of 4:
The n-th term of a sequence with first term equal to <em>a</em> and common ratio <em>r</em> is:
The first term of this sequence is 15 and the common ratio is 4, then the nth term is:
Substitute <em>n=6</em> to find the 6th term:
Therefore, the 6th term of the sequence, is:
Answer:
This is the concept of application of the Pythagorean theorem. The resultant speed of the motorboat which is crossing the river that has a northward current of 5 m/s at a speed of 8 m/s will be given by:
c^2=a^2+b^2
c^2=8^2+5^2
c^2=64+25
c^2=89
c=sqrt89
c=9.4 m/s
Explanation
Step 1
solve for each factor:
set each factor equal to zero
so, we have 3 critical numbers
-3,-1 and 1
Step 2
now, let's make a table to evaluate each interval , (select a number from the interval)
b) (x+1)
c)(x-1)
Step 3
now, make th multiplication of the signs ( check the table in step 2)
so, we got
(-infi, -1) U (1, inf)
as we need that the product of the factors is greater than zero ( positive) , the solution is( set notation)
I hope this helps you
