Which ordered pair is a solution of the equation?<br> 7z -5 = 4y -6<br> Choose 1 answer:

ELEN [110]

Step-by-step explanation:

7z-5=4y-6

-4y=-6-7z+5

-4y=-1-7z

y=1/4+7/4z

y=7/4z+1/4

7z=4y-6+5

7z=4y-1

z=4/7y-1/7

Which equations for the measures of the unknown

MAXImum [283]

Answer: Option B, Option C, Option E

Step-by-step explanation:

The options written correctly, are:

$A)x = cos^{-1}(\frac{a}{c})\\\\B) x = sin^{-1}(\frac{c}{b})\\\\C)x = tan^{-1}(\frac{c}{a})\\\\D) y = sin^{-1}(\frac{a}{c})\\\\ E)y = cos^{-1}(\frac{c}{b})$

For this exercise you need to use the following Inverse Trigonometric Functions:

$1)\ sin^{-1}(x)\\\\2)\ cos^{-1}(x)\\\\3)\ tan^{-1}(x)\\\\$

When you have a Right triangle (a triangle that has an angle that measures 90 degrees) and you know that lenght of two sides, you can use the Inverse Trigonometric Functions to find the measure of an angle $\alpha$ :

$1)\alpha = sin^{-1}(\frac{opposite}{hypotenuse}) \\\\2)\ \alpha =cos^{-1}(\frac{adjacent}{hypotenuse})\\\\3)\ \alpha=tan^{-1}(\frac{opposite}{adjacent})$

Therefore, the conclusion is that the angles "x" and "y" can be found with these equations:

$x=sin^{-1}(\frac{c}{b})\\\\x= cos^{-1}(\frac{a}{b})\\\\x=tan^{-1}(\frac{c}{a})\\\\\\ y=sin^{-1}(\frac{a}{b})\\\\y=cos^{-1}(\frac{c}{b})\\\\y=tan^{-1}(\frac{a}{c})$

Seth traveled 1 mile in 57.1 seconds. About hos fast does Seth travel in miles per hour?

mars1129 [50]

Seth traveled 1mi/57.1s

you need to convert mi/s to mi/h

we need to found how many seconds are in an hour (3,600)

so 3,600/57.1=63.047

63.047mi/h

63mi/h (rounding)
