10^x=0.1 \% \times 10^y \\ \\
10^x=\frac{0.1}{100} \times 10^y \\ \\
10^x=\frac{1}{1000} \times 10^y \\ \\
10^x=\frac{10^y}{10^3} \\ \\
10^x=10^{y-3} \\ \\
\log_{10} 10^x=\log_{10} 10^{y-3} \\ \\
x=y-3 \\ \\
y=x+3

The answer is B.

Olenka [21]

Answer:

The correct answer is:

f(3)=23

Step-by-step explanation:

By evaluating first, and then the mathematical calculation, we have:

f(3)= 3^{2} + 2 ×3^{2} - 3 -1 

= 9 +18 -3-1

Guys Help!! I Don´t Know How To Do This!!

Answer:

Frank

Step-by-step explanation:

First let's start by calculating the speed of each runner.

Let's use feet per second

Frank's speed is already given in feet per second: 14 feet/second

We are given that Jake runs 382 feet in 38 seconds. To bring this down to feet/second we need to divide both numbers by 38.

382/38=10.05 feet/second (about)

We are given that Will runs 1 mile in 394 seconds. 1 mile is equivalent to 5280 feet. Now we divide both numbers by 394 to bring it down to feet/second.

5280/394=13.401  feet/second (about)

We are given that Ron runs 555 feet in 1 minute. 1 minute is equivalent to 60 seconds. Now we divide both numbers by 60 to bring it down to feet/second.

555/60=9.25 feet/second

After comparing all the speeds, we can conclude that Frank runs the fastest
