Answer:
Option C.
Step-by-step explanation:
We know that
f(t) = 1.5t + 50
represents the approximate population of trout in Sky Lake
And
g(t) = 0.1t^2 - 4t + 70
represents the approximate population of trout in Lake Cyan
The total trout population in the area is described as
f(t) + g(t)
f(t) + g(t) = [1.5t + 50] + [0.1t^2 - 4t + 70]
f(t) + g(t) = [1.5t + 50+ 0.1t^2 - 4t + 70]
f(t) + g(t) = [0.1t^2 -2.5t + 120]
f(t) + g(t) = 0.1t^2 -2.5t + 120
Option C.
Answer:
sum of exterior angles of a polygon = 360°
therefore,
x + 5 + x + 10 + 3x - 8 + 5x + 10 = 360°
10x + 17 = 360°
x + 17 = 360 ÷ 10 = 36
x = 36 - 17 = 19
x = 19
<h3>rounding off 19 to nearest hundred = 20 </h3>
value of x will be 20
Answer:
Yes, it passes the <em>vertical line test</em>.
Step-by-step explanation:
If you can pass a vertical line through the graph, and if it only touches the line ONCE, then it's a function. Otherwise, it's not-- you can't be in two places at 1 time...
Answer:
B. (0, 6).
Step-by-step explanation:
The y-intercept is found by putting x = 0 and finding the values of y:
y = -5(0) + 6
y = 6 so the y-intercept is (0, 6).
