Answer:
110
Step-by-step explanation:
Triangles equal to 180
180-19=161
161-51=110
Answer:
A
Step-by-step explanation:
Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then
minimum/ maximum value is the y- coordinate of the vertex.
The x- coordinate of the vertex is
= - 
y = x² - 
x + 
← is in standard form
with a = 1 and b = - , thus
= - 
= 
Substitute this value into y
y = ( )² - ( ) +
= 
- 
+ = 
Since a > 1 then the vertex is a minimum, thus
minimum value = → A
Answer:
Coordinates of E is (-2,7)
Step-by-step explanation:
Midpoint = ((x1+x2)/2,(y1+y2)/2)
xK = (xW + xE)/2 => xE = 2xK - xW = 2(0) - 2 = -2
yK = (yW + yE)/2 => yE = 2yK - yW = 2(3) - (-1) = 7
Answer:
Step-by-step explanation:
distance = rate * time.( d = rt).....rate is speed....but we are looking for rate, so let me rearrange this formula...... r = d / t
r = d / t
distance (d) = 40m
time (t) = 10 seconds
so the rate (speed) can be found thru division....
r = 40 / 10 = 4m per second
so 40 divided by 10 is ur answer <===
Answer: scalene, right
Step-by-step explanation:
None of the side lengths of the triangle are equal, so the triangle is scalene.
This triangle also has a right angle, so it is a right triangle.
