Snowcat [4.5K]

Answer:

C. -0.7

Explanation:

Given the equation:

$\frac{1}{2}(-1.4m+0.4)=\boxed{\square}_{}m+0.2$

First, distribute the bracket on the left-hand side:

$\begin{gathered} \frac{1}{2}(-1.4m)+\frac{1}{2}(0.4) \\ =-0.7m+0.2 \end{gathered}$

The number that makes the given expressions equivalent is -0.7.

The correct choice is C.

Tan 1.1 – tan 4.6/

VladimirAG [237]

The value of the given equation is –0.37458.

Solution:

Given equation is:

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}$

Let us first find the values.

The value of tan 1.1 = 1.96475

The value of tan 4.6 = 8.86017

Substitute these values in the given equation.

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}$

$$=\frac{1.96475-8.86017}{1+1.96475 \times 8.86017}$

$$=\frac{-6.89542}{1+17.4080}$

$$=\frac{-6.89542}{18.4080}$

= –0.37458

$$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}=-0.37458$

Hence the value of the given equation is –0.37458.
