This is one of the two tired triangles of trig you should memorize. An isosceles right triangle has its sides in ratio $1:1:\sqrt 2$ . That means the hypotenuse is the square root of two times either side.

$u = \sqrt{2} \times \sqrt{2} = 2$

Answer: C

If you didn't know you could write

$v = \sqrt 2$

$v^2 + v^2 = u^2$

$u^2 = 2 + 2 = 4$

$u = 2$

How do you solve thus ? 8=8v-4(v+8)

Harrizon [31]

8 = 8v - 4 (v + 8)

Distribute the 4 through the parentheses

8 = 8v - 4v - 32

combine like terms

8 = 4v - 32

add 32 to both sides

8 + 32 = 4v -32 + 32

combine like terms

40 = 4v

divide each side by 4

40/10 = v

4 = v

v= 4

Convert each degree measure into radians

dimaraw [331]

radians = degrees x PI/180

radians = 60 x pi/180 = 1.04719 radians

round answer as needed

if you need it in terms of pi it would be PI/3 radians

Write an equation of the line in slope-intercept form. JY 1 (3, 3) (0, 2) 2 4 y=

stellarik [79]

Correct answer: y = $\frac{1}{3}$ x + 2

To find out the slope, you would need to remember this slope formula: $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ . We can use the two points provided on the graph to figure out the slope. We can label (3, 3) as $x_{1}$ and $y_{1}$ , and (0, 2) as $x_{2}$ and $y_{2}$ . Now we can plug these numbers into the slope formula to find out the slope:

m = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ → $\frac{2-3}{0-3}$ → $\frac{-1}{-3}$ → $\frac{1}{3}$

To find out the y-intercept, just substitute (3, 3) into the slope-intercept formula ( y = mx + b ) with the slope that is substituted for 'm' that we already solved earlier.

y = mx + b

(3) = $\frac{1}{3}$ (3) + b

3 = 1 + b

2 = b

You can also prove this true by looking at the graph provided. The line intersects at the y-axis at 2.

Now we know that m = $\frac{1}{3}$ and b = 2, we can substitute it into the slope-intercept formula. Thus, the answer is y = $\frac{1}{3}$ x + 2.

Hope this helps you! Let me know if you have any more questions related to this problem.

Use the scenario to answer the question. Tyrone was asked to write the recursive and explicit formula for the sequence {−4,−7,−1

Anton [14]

The last option: In his recursive formula, he should have the term an−1 instead of −4 to get an=an−1−3.
