Answer:

Step-by-step explanation:

4+9+14+...+494

d=9-4=5

\[a_{n}=a_{1}+(n-1)d\]494=4+(n-1)5\\490=(n-1)5\\n-1=98\\n=98+1=99\\S_{n}=\frac{99}{2} (4+494)\\=99*\frac{498}{2} \\=99*249\\=24,651

Please help with this I keep gettin the wrong answer!!!
BaLLatris [955]

Answer:

Denote the distance from initial position of Emily to the park is D

=> As the first speed is 5 (mile/hour) and second speed is 9 (mile/hour) and total time is 1 and 5/9 hour, we have:

D/5 + D/9 = 14/5

=> (9D + 5D)/45 = 14/5

=> 14D/45 = 126/45

=> 14D = 126

=> D = 9 (mile)

Hope this helps!

:)

8m²n³-24m²n²+4m³n<br> how do I factor out the GCF
mariarad [96]

Answer:

8 {m}^{2}  {n}^{3}  - 24 {m}^{2} {n}^{2}   + 4 {m}^{3}n = 4 {m}^{2} n(2 {n}^{2}  - 6n + m)

Step-by-step explanation:

The given expresion is

8 {m}^{2}  {n}^{3}  - 24 {m}^{2} {n}^{2}   + 4 {m}^{3}n

Observe that 4 is common to 8,-24, and 4

Observe also that, m²n is common to all the terms.

Hence the GCF is:4m²n

We factor the GCF to get;

8 {m}^{2}  {n}^{3}  - 24 {m}^{2} {n}^{2}   + 4 {m}^{3}n = 4 {m}^{2} n(2 {n}^{2}  - 6n + m)
