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

URGENT!!!! WILL GIVE BRAINLIEST TO FIRST RIGHT ANSWER!!!!!!
Zepler [3.9K]

geometric sequence

\tt U_n=ar^{n-1}

a = 6 = first term

r = ratio = \tt \dfrac{9}{6}

the 6th term (n=6)

\tt U_6=6\times (\dfrac{9}{6})^{6-1}\\\\U_6=6\times \dfrac{9}{6}^5\\\\U_6=\dfrac{9^5}{6^4}=45.5625\rightarrow rounded~to nearest~thousandth=45.563

Determine the standard form of the equation for the circle with center (h,k) = (-5 ½) and radius r =1
wariber [46]
Asuuing yo meant (h,k)=(-5,1/2)

equation is (x-h)^2+(y-k)^2=r^2
(h,k) is center and r=radious
given that (h,k)=(-5,1/2) and r=1
h=-5
k=1/2

(x-(-5))^2+(y- \frac{1}{2} )^2=1^2
(x+5)^2+(y- \frac{1}{2} )^2=1
if you wanted us to expand
x²+y^2+10x-y+25.25=1
