Centi = Hundreds.
1.5533.
Round up by seeing if the number to the right of the hundreds place is 5 or higher. If it's not, don't change anything.
1.55 is your answer.
Step-by-step explanation:
You need to use trigonometric stuff here. Since you're given the hypotenuse and an angle you can plug that right into an equation.
Recall that sin is opposite over hypotenuse and cos is adjacent over hypotenuse.
Now that you know the opposite side (DC) you can use tan, too, but I'm going to use cos.
This is the adjacent side (BC). I put it in its exact value, but in decimal form it's ≈12.124.
Now you can do the perimeter:
Your answer is the 38.2
Answer:
Step-by-step explanation:
<u>When the line is given in standard form:</u>
- ax + by = c, it has slope of -a/b
<u>Given line:</u>
<u>It has a slope:</u>
A line perpendicular to the given should have a slope m = 1 as negative reciprocal to the given
<u>Let's see which line has the slope of 1:</u>
- 1. m = -(-1)/6 = 1/6 - NO
- 2. m = -4/4 = -1 - NO
- 3. m = -2/4 = -1/2 - NO
- 4. m = -(-2)/2 = 1 - YES
Correct option is D
Answer:
y- axis
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y )
Consider the corresponding vertices
A(- 1, - 1 ) → A'(1, - 1 )
B(- 2, - 1 ) → B'(2, - 1 )
C(- 2, - 4) → C'(2, - 4 )
These coordinates satisfy the condition for reflection in the y- axis
Answer:
Step-by-step explanation:
This is the slope-intercept form 
where 
stands for the slope and 
stands for the y-intercept. The slope in the picture is 9/1 or just 9 simply. The y-intercept, or where the line crosses the y-axis is at 0 so you don't have to write if there's a 0.
Hope this helps
