Answer:

lower your mortgage interest rate

Step-by-step explanation:

The higher your credit score, the __lower your mortgage interest rate__.

Because the higher your credit score, the less risk you represent for a lender, so it will most likely grant you a lowest rate for your mortgage/loan.

The "lower your savings interest rate " is not the answer because savings interest rates are not related to the credit score...

"higher your car loan rate " and "higher risk you are to a creditor " are consequences of a low credit score.

If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s, what is the acceleration of the objec

SVETLANKA909090 [29]

Answer

Find out the what is the acceleration of the object .

To prove

Formula

$Acceleration = \frac{Final\ velocity - Intial\ velocity}{Time }$

Where

t = the time in which the change occurs

As given

If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s .

Final velocity = 98 m/s

Intial velocity = 65 m/s

Time = 12 s

Put in the formula

$Acceleration = \frac{98 - 65}{12}$

$Acceleration = \frac{33}{12}$

Acceleration = 2 .75 m/s ²

Option (A) is correct .

REALLY APPRECIATE YOUR HELP<br><br>Given log x = 3 and log y = 2, prove that x^2 -7xy =3000y

anyanavicka [17]

Answer:

$if \: log(x ) = 3 \\ log_{10}(x) = 3 \\ {10}^{3} = x \\ therfore \to \: \boxed{x = {10}^{3} } \\ \\ if \: log(y ) = 2 \\ log_{10}(y) = 2 \\ {10}^{2} = y \\ therfore \to \: \boxed{y= {10}^{2} }$

Step-by-step explanation:

$x^2 -7xy =3000y \: then \to \\ x^2 =3000y + 7xy \\ {(10 ^{3} )}^{2} = 3000(10)^{2} + 7( {10}^{3} \times {10}^{2}) \\ {10}^{6} = 3000(10)^{2} + 7( {10}^{3} \times {10}^{2}) \\ {10}^{6} = 3000(10)^{2} + 7( {10}^{5} ) \\ {10}^{6} = 300000 + 700000 \\ \boxed{{10}^{6} = 1000000} \\ hence \: the \: equation \to \: x^2 -7xy =3000y \\ \boxed{ is \: corret}$
