Step-by-step explanation:
Line AB = sqrt18 = 4.24
Line BC = sqrt10 = 3.16
Line AC = 4
Since the triangle cannot be isosceles or equilateral, the best option here is scalene.
Answer:
D) 70 ft
Step-by-step explanation:
1 inch = 20 feet
3 1/2 inches= 20 feet*3 1/2 inches
= 70 ft
Answer:
x > 3
Step-by-step explanation:
Here, we want to write the inequality represented
We start by looking at the value on which we have the circle
It is on the value 3
we can also see that the circle is unshaded and also that, the graph faces the right direction
As the circle
is unshaded, we have it that we only use the inequality without the equal to
So we have the representation as;
x > 3
Answer:
(-5, 50) and (-1/3, -0.815)
Step-by-step explanation:
The equation is;
y = x³ + 8x² + 5x
Now the turning point will occur at where dy/dx = 0.
Thus;
dy/dx = 3x² + 16x + 5
At dy/dx = 0, we have;
3x² + 16x + 5 = 0
From quadratic formula, we can get;
x = -5 or -⅓
Thus, let's find y at this points.
y = -5³ + 8(-5)² + 5(-5)
y = -125 + 200 - 25
y = 50
Also,at x = -⅓, we have;.
y = (-⅓)³ + 8(-⅓)² + 5(-⅓)
y = -1/27 + 8/9 - 5/3
y = -0.815
Thus,the coordinates of the turning points are;
(-5, 50) and (-1/3, -0.815)
