Keith’s dog weighs 90 pounds and a healthy dog’s weight is less than 75 pounds. If Keith’s dog looses 1.25 pounds per week, how

vivado [14]

Answer:

12 weeks.

Step-by-step explanation:

Keiths dog will need to lose 15 pounds to get down to 75 pounds. If he loses 1.25 pounds per week, it will take 12 weeks to get down to 75 pounds. To figure this out, you would use the equation:

90 - 75 = 15

15 / 1.25 = 12

That is how you would get 12 weeks.

What is a formula for the nth term of the given sequence? 15,75,375

spin [16.1K]

Answer:

3 × 5 ^ n

Step-by-step explanation:

since the series is exponential, the ratio between adjacent terms is 5.

nth term of geometric/exponential series is given by:

nth term = first term × (ratio)^(n-1)

= 15 × 5^ (n-1)

= 15 × 5^n × 5^-1

= 3× 5^n

PLEASE HELP LAW OF COSINES

chubhunter [2.5K]

The Law of Cosine states
cos $C=(a^2+b^2-c^2)/2ab$

so plugging in the numbers gives us

cos $J=(13^2+19^2-11^2)/2(13*19) = 409/494$

We now have cosJ so plug that into your calculator and find arccos (arccos(cos(J)) = J)
arccos $(409/494)=34.11$
rounding your answer will give you 34°
