Two lines that intersect and form right angles are called perpendicular lines. The symbol ⊥ is used to denote perpendicular lines.
Answer:
12.5in.
x=.5t+11
Step-by-step explanation:
First of all, create the equation so you can solve both questions at once. We know that Sydney had eleven inches of snow on her lawn, and it doesn't dissapear, so it starts with x=11. Then every hour she gets .5 inches per hour, and the amount of hours is t, so that will translate to .5t. that makes the equation x=.5t+11. To find out how much she would have in three hours, substitute 3 for t, which which goes like this: x=.5(3)+11
x=1.5+11
x=12.5
The resulting function will have a function f(x) = √x-3 -1
<h3>Translation of coordinates</h3>
Translations is a transformation technique that changes the position of an object from one point on the plane to another.
Given the function below
y = √x
If the translated technique below is applied (x,y) -> (x-3,y +1), the resulting function is given as:
y+1 = √x-3
Subtract 1 from both sides
y + 1 - 1 = √x-3 - 1
y = √x-3 -1
Hence the resulting function will have a function f(x) = √x-3 -1

#SPJ1
Exterior angle sum of an polygon (shape) is 360 degrees (this is a property)
x + 98 + 41 + 76 + 86 = 360
Therefore x = 59
Please double check the equation I have written. Your picture is a bit blurry therefore I can really tell what number is 6 and 8. Sorry
Answer:
12
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 9)² + (y - 4)² = 36 ← is in standard form
with r² = 36 ⇒ r = 
= 6
diameter = 2 × r = 2 × 6 = 12
