Answer:
10.8 miles
Step-by-step explanation:
The distance between (-3, -4) and (3, 5) can be found using the distance formula.
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((3 -(-3))^2 +(5 -(-4))^2) = √(6^2 +9^2) = √117
d ≈ 10.8
It is about 10.8 miles from the mall to the park.
the lower the valance electrons the more reactive the element.
Since Element B has few electrons it is more reactive
so the answer is Element A is less reactive but will still react
Answer:
Increasing → (-∞, -0.5)
Decreasing → (-0.5, ∞)
Step-by-step explanation:
From the picture attached,
Vertex of the parabola represents the highest point of the curve of a quadratic function 'f'.
Left part from the vertex is increasing and the right side is increasing.
x-coordinates of the vertex,
x = -0.5
Therefore, graph of the function is increasing in the interval (-∞, -0.5)
And decreasing in the interval (-0.5, ∞).
Answer:
a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-one number called the common ratio. hope this helped :)
Step-by-step explanation:
Let's assume two variables x and y which represent the local and international calls respectively.
x + y = 852 = total number of minutes which were consumed by the company (equation 1)
0.06*x+ 0.15 y =69.84 = total price which was charged for the phone calls (Equation 2)
from equation 1:-
x=852 -y (sub in equation 2)
0.06 (852 - y) + 0.15 y =69.84
51.12 -0.06 y +0.15 y =69.84 (subtracting both sides by 51.12)
0.09 y =18.74
y= 208 minutes = international minutes (sub in 1)
208+x=852 (By subtracting both sides by 208)
x = 852-208 = 644 minutes = local minutes
