An earthquake measured 8.4 on the Richter Scale. Use the formula R = log I to find the intensity, I, of the earthquake.​ NO LINK
TEA [102]

Answer:

I ≈ 251188643

Step-by-step explanation:

Given

R = logI [ note log I = log_{10} I ]

Using the rule of logarithms

log_{10} x = n ⇒ x = 10^{n}

Substitute R = 8.4 into the equation, then

logI = 8.4

I = 10^{8.4} ≈ 251188643

Write an equivalent expression for -3t+4q+5t-7q
steposvetlana [31]

Answer:

The equivalent expression can be given as:

⇒  2t-3q

Step-by-step explanation:

Given expression:

-3t+4q+5t-7q

To write an equivalent expression:

Solution:

In order to write an equivalent expression, we will combine the like terms. By like terms, we mean the terms with the same variable constant.

For example : 5x and -3x  are like terms.

We have:

-3t+4q+5t-7q

Combining like terms :

⇒ -3t+5t+4q-7q

⇒  2t-3q

Thus, the equivalent expression can be given as:

⇒  2t-3q

A child throws a ball with a speed of 5 feet per second at an angle of 73 degrees with the horizontal. Express the vector descri
maxonik [38]

Answer:

  v = 5cos(73°)i +5sin(73°)j

Step-by-step explanation:

The components of the velocity vector are ...

  horizontal (i direction): 5·cos(73°)

  vertical (j direction): 5·sin(73°)

Then the velocity vector is the sum of these component vectors:

  v = 5cos(73°)i +5sin(73°)j
