Step-by-step explanation:
total ratio is 5
first find the total amount
bob's ratio is 2/5
so 2/5 ×total amount=8 pounds
0.4 ×total amount=8 pounds
total amount=8/0.4=20 pounds
so chris receives: 20-8=12 pounds
The equation for a parabola can also be written in the "vertex form":
y = a (x - h) ^ 2 + k
In this equation, the vertex of the parabola is the point (h, k).
We have then:
y = 2x2 + 16x + 17
We look for the vertice:
0 = 4x + 16
x = -16 / 4
x = -4
Substituting:
y = 2 * (- 4) ^ 2 + 16 * (- 4) +17
y = -15
Substituting the given point:
y = 2 (x +4) ^ 2 - 15
Answer:
y = 2 (x +4) ^ 2 - 15
option C
Answer:
Rate of Change = -77.9 feet/year
My interpretation: "Is Bad."
Step-by-step explanation:
The rate of change is the number of feet that Lake Powell dropped, divided by the number of years the drop took place. We want a value with a unit of feet/year.
<u>Year</u> <u>Feet</u>
1999 3893
2005 3425.6
<u>Change</u>
Year = (2005 - 1999) or 6 years
Feet = (3425.6 - 3893) or -467.4 feet
Rate of Change = (-467.4 feet)/(6 years)
Rate of Change = -77.9 feet/year
=======================
FYI: Lake Powell is 22.39 feet lower today (June 23, 2022) than it was 1 year ago.
Considering that the pace is estimated in the hundreds per hour, 4 hours after the park opens, there are 92 visitors based on the formula (e - l)(4). This is further explained below.
<h3>Exactly what is the definition of a function?</h3>
This phrase describes the connection between two variables.
The function is given as e(x)=0.03x^3+2,
The substraction of function
(e-l)(x)
ex-lx
Hence
(e-l)(x)=0.03x^3+2-(0.5x+1)
(e-l)(x)=0.03x^3-0.5x+1
Hence for x=4
(e-l)(4)=0.03*4^3-0.5(4)+4
(e-l)(4)=0.92
