1 answer:

5 0

Csc x · sec x - tan x =
= 1 / sin x · 1 / cos x - sin x / cos x =
= 1 / sinx cos x - sin² x / sin x cos x =
= ( 1 - sin² x ) / (sin x cos x) =
= cos² x / ( sin x cos x ) =
= cos x / sin x = cot x

Belinda bought a car for 10% off the $21,957.68 sticker price. The sales tax was 6.5% of the sale price. She had to pay a $528.0

Answer:

$21,574.43

Step-by-step explanation:

To start off, we need to take 10% off of the starting price of $21,957.68. We can do that by multiplying that number by 0.10. The work is shown below...

(21,957.68) x (0.10) = 2,195.77

Now we can take the number 2,195.77 and subtract that from our starting price.

21,957.68 - 2,195.77 = 19,761.91 (this is our price after the 10% sale)

Next, we need to add on the sales tax. We simply multiply 19,761.91 by the decimal version of 6.5% which is 0.065.

(19,761.91) x (0.065) = 1,284.52

Now we add that number to 19,761.91

19,761.91 + 1,284.52 = 21,046.43

Since we have our current cost after sales tax, we now just need to add the $528 license fee...

21,046.43 + 528 = $21,574.43

Write 169=13^2 in logarithmic form

e-lub [12.9K]

Answer:

$\log_{13}(169)=2$

Step-by-step explanation:

The given exponential form is:

$169=13^2$

The base of the given expression on the right is 13 and the exponent is 2.

The number is 169.

In terms of logarithms, the base still remains the base and the exponent becomes the result of the logarithm of the number 169 to the given base 13.

$\log_{13}(169)=2$
