Answer:

√2/4 + 1

Step-by-step explanation:

sin 45° --> √2/2

cos 60° --> 1/2

tan 45° --> 1

with these values, we write a new expression

√2/2 × 1/2 + 1

√2/2 × 1/2 = √2/4

(by doubling the denominator, you are splitting the number in half as implied by the 1/2)

your answer is √2/4 + 1

goodluck :)

Use a graphing calculator to solve the equation -2sin(theta)= 1.2 in the interval from 0 to 2pi.

elena-s [515]

Answer:

$\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64$

Step-by-step explanation:

As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:

$\theta=3.7\\\\and\\\\\theta=5.7$

So, it's useful to solve the equation too, in order to verify the result:

$-2sin(\theta)=1.2\\\\sin(\theta)=-\frac{3}{5}$

Taking the inverse sine of both sides:

$\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64$

Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:

$\theta\approx 3.785\\\\\theta \approx 5.64$

The perimeter of a rectangle is 14x - 8 feet. If the width of the rectangle is 5x, what is the rectangle's length?

wariber [46]

Length = 2x+4

Step-by-step explanation:

P=2W+2L

14x+8 =2(5x)+2L

14x+8=10x+2L

14x+8-10x=2L

4x+8=2L

(4x+8)/2=L
