Gven the following table, find the rate of change between f(-4) and f(0)
x -4 -2 0 2 4
f(x) -2 -1 0 1 2
A. -2
B. 2
C. -1/2
D. 1/2
we know that
the rate of change is equal to
(f(b)-f(a))/(b-a)
f(b)=f(0)
f(a)=f(-4)
b=0
a=-4
(f(0)-f(-4))/(0+4)
we have that
f(0)=0
f(-4)=-2
substitute
(0+2)/4
2/4
1/2
therefore
<h2>the answer is the option D</h2>
Multiply the price of the van by the sales tax:
26,857 x 0.06 = 1611.42
Add the sales tax and the cost of the fees to get the total cost:
26857 + 1611.42 + 250 = 28,718.42
Now multiply that by 20% and subtract from the total:
28,718.42 x 0.20 = 5743.68
28718.42 - 5743.68 = 22974.74
They are financing $22,974.74
Answer:
∠ DEB = 101.97°
Step-by-step explanation:
BCDE is a cyclic quadrilateral, whose opposite angles are supplementary, so
∠ BCD + ∠ DEB = 180°, that is
78.03° + ∠ DEB = 180° ( subtract 78.03° from both sides )
∠ DEB = 101.97°
The height of the balloon above the ground is about 7.07 feet.
<h3>
What is trigonometric ratio</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the balloon from the ground, hence:
sin(45) = h/10
h = 7.07 feet
The height of the balloon above the ground is about 7.07 feet.
