If I pick n, it becomes 50(2n+5)+1764-2001 this is the expression
Average rate=delta y/delta x...
c=(72-48-8+16)/(6-2)
c=32/4
c=8
Answer:

Step-by-step explanation:
If the angle θ is in radians, the formula for the area (A) of a sector of a circle is
A = ½r²θ
If θ is in degrees

Data:
θ = 49°
r = 11 cm
Calculation:

Answer:
r= d/2
7/2
3.5
3.5 is the answer
Step-by-step explanation:
Step-by-step explanation:
there must be something wrong with your text.
what we can see is
3.8 × 105
and
1.9 × 1022
the true answer for these values has nothing to do with the 4 answer options.
maybe you meant
1.9 × 10.5 ?
because that answer would be 20.
but first working with the presented numbers :
3.8 × 105 = 399
1.9 × 1022 = 1941.8
so, the second number is actually much bigger than the first number.
but if it is
1.9 × 10.5 = 19.95
that works.
and we can either use the calculator to calculate
399 / 19.95 = 20
or we can simply look at the factor changes of the multiplication terms.
3.8 = 1.9 × 2
105 = 10.5 × 10
so, the multiplication product of the two larger numbers is then 2×10=20 times larger than the product of the 2 smaller numbers.
