Answer:
When it is reflected across y=-2, the new location will be at (-5,-4)
Step-by-step explanation:
y=-2 is a horizontal line. The points B(-5,0) is 2 units above that point. So, when reflected, it will move 4 units down, which gives you (-5,-4).
4 hours = 304 miles.
1 hour = 304 ÷ 4
1 hour = 76 miles
7 1/2 hours = 76 x 7 1/2
7 1/2 hours = 570 miles.
------------------------------------------------------------------
Answer: It will travel 570 miles in 7 1/2 hours.
------------------------------------------------------------------
the equation is,
a_n = a_(n–1) + 3 * n + 2
Substituting the values
for day 4, <span>
<span>20 + 3*4 + 2 = 34<span>
Thus the equation is correct</span></span></span>
Therefore to calculate
for a_n at n = 7 or a_7, we must calculate a_5 and a_6 first.
a_5 = 34 + 3*5 + 2 = 51
a_6 = 51 + 3*6 + 2 = 71
Hence,
a_7 = 71 + 3*7 + 2 = 94
Answer: D. 94
Answer:
infinite amount
Step-by-step explanation:
phone numbers can be generated at an infinite amount or close to infinite, the number is crazy 7,970,000,000 is the exact though
Answer:
vertex (5,2)
axis of symmetry: x=5
Step-by-step explanation:
vertex (h,k)
y = a(x - h)² + k
f(x)=(x-5)²+2 a = 1 h = 5 k = 2
vertex (5 , 2)
The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
x = 5
