Answer:

$f^{-1}(x)=\frac{3(x-5)}{5}$

Step-by-step explanation:

$f(x)=y=\frac{5x}{3}+5\\y-5=\frac{5x}{3}\\3(y-5)=5x\\x=\frac{3(y-5)}{5}\\ => f^{-1}(x)=\frac{3(x-5)}{5}$

Quadrilateral WXYZ is the result of a translation of quadrilateral ABCD . AB¯¯¯¯¯ is parallel to DC¯¯¯¯¯ in the pre-image. Drag

tigry1 [53]

The corresponding segments WX and ZY in the image are parallel.

When a shape is translated from location to another, the size and shape of the figure do not change. Therefore, lines that are corresponding are still parallel.

Tan^2 70° -sec^2 70°

kipiarov [429]

Answer:

-1

Step-by-step explanation:

We need to find the value of tan² 70° -sec² 70°.

We know that,

$\sec^2\theta-\tan^2\theta=1$ ...(1)

We can write the given expression as :

tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)

=-(sec² 70°-tan² 70°)

Using identity (1)

=-(1)

= -1

Hence, the value of the given expression is -1.
