Answer:
13.5 inches
Step-by-step explanation:
3inches:10 miles
x inches: 45 miles
do cross multiply:
3*45=135
10*x=10x
so 135=10x
x=13.5 inches
Time = 6hours
Distance = 38.4 Km
Speed = distance /time
= 38.4/6
= 6.4 km/h
Answer:
F(x) = -3(x + 2)² - 2
Step-by-step explanation:
In the picture attached, the graph is shown.
F(x) has the form a(x - h)² + k, where (h, k) is the vertex of the parabola. We can see in the graph that the vertex is located at (-2, -2), then F(x) = a(x + 2)² - 2. If a > 0 the parabola opens upward, if a < 0 the parabola opens downward. We can see in the graph that the parabola opens downward, then the correct answer is F(x) = -3(x + 2)² - 2
Answer:
If the value of a is negative the line is decreasing.
Step-by-step explanation:
The value of a, the coefficient of x, is the slope.
If the slope is positive, the line is increasing from left to right.
If the slope is negative, the line is decreasing from left to right.
Answer:
We have 2 3/5 - 1 1/5 = 13/5 - 6/5 = 7/5 = 1 2/5;
