Hey there!

The answer to your question is  45\frac{9}{10}

We can find this by simply plugging in the "r" value into the given equation.

46 + \frac{1}{5} (\frac{-1}{2})

Now we evaluate the equation:

46 + \frac{1}{5} (\frac{-1}{2})

46 + \frac{-1}{10}

45\frac{9}{10}

Hope this helps and have an amazing day!

Answer:

45\frac{9}{10} or 45.9

Step-by-step explanation:

All we have to do here is substitute the given value of r into the given expression. Therefore, after substituting r=-\frac{1}{2} into 46+\frac{1}{5}r, we get:

46+\frac{1}{5}r

= 46+\frac{1}{5}*(-\frac{1}{2} ) (Substitute r=-\frac{1}{2} into 46+\frac{1}{5}r)

=46-\frac{1}{10} (Multiply)

=45\frac{9}{10} or 45.9 (Simplify)

Hope this helps!

Solve the equation sin theta = 0.3 to the nearest tenth. Use the restrictions 90degrees < theta < 180degrees.
Alexxandr [17]
We first do:
∅ = sin⁻¹(0.3)
∅ = 17.5°

To go into the second quadrant, we add 90°.
∅ = 17.5 + 90
= 107.5°
The answer is A.

Write the following quotient in the form a+bi.<br> -7i/2-7i
Helga [31]

Answer:

\large\boxed{\dfrac{49}{53}-\dfrac{14}{53}i}

Step-by-step explanation:

\text{Use}\\\\i=\sqrt{-1}\to i^2=-1\\\\(a-b)(a+b)=a^2-b^2\to(a-bi)(a+bi)=a^2+b^2\\\\\text{distributive property}\ a(b+c)=ab+ac\\---------------------\\\\\dfrac{-7i}{2-7i}=\dfrac{-7i}{2-7i}\cdot\dfrac{2+7i}{2+7i}=\dfrac{-7i(2+7i)}{2^2+7^2}=\dfrac{(-7i)(2)+(-7i)(7i)}{4+49}\\\\=\dfrac{-14i-49i^2}{53}=\dfrac{-14i-49(-1)}{53}=\dfrac{-14i+49}{53}\\\\=\dfrac{49}{53}-\dfrac{14}{53}i
