Answer:

f(x)=19

Step-by-step explanation:

pemdas (parentheses exponents multiplication division addition, and subtraction), basically you solve the equation in that order so 2*3^2+1 since there is no parentheses you go to exponents which would be 3^2 which is 9 so 2*9+1 then multiplication and/ or division which in this case we have division so 2*9= 18 and then lastly addition and/ or subtraction which we have addition so 18+1= 19 therefore f(x)=19

Answer:

F(3) = 19

Step-by-step explanation:

f(x)=2x^2+1, when x=3, means

f(3)=2(3^2)+1

f(3)=2(9)+1

f(3)=18+1

f(3)=19

Kevin hiked up lambs Canyon and two hours and then ran back down in one hour has been running downhill was 2.8 mph greater than
coldgirl [10]

Answer: he hiked 5.6 miles up the canyon.

Step-by-step explanation:

Let x represent his speed hiking uphill.

His speed running downhill was 2.8 mph greater than his speed hiking uphill. This means that his speed running downhill would be x + 2.8

Distance = speed × time

Kevin hiked up Lamb’s Canyon in 2 hours. This means that the distance covered by hiking uphill is 2 × x = 2x

He ran back downhill in 1 hour. This means that the distance covered by running downhill is 1 × (x + 2.8) =

x + 2.8

Since the distance uphill is the same as the distance downhill, then

2x = x + 2.8

2x - x = 2.8

x = 2.8

Therefore, the distance hiked up the canyon is

2x = 2 × 2.8 = 5.6 miles
