Answer:
8 ft
Step-by-step explanation:
h(x)=-0.0085x²+0.25x+6,
The maximum height will be at the vertex
The x coordinate is at
h = -b/2a where b is the x term coefficient and a is the x^2 term coefficient
h = -(.25)/(2(-.0085)
=14.70588235
We want to find the height so we need to substitute this into the equation
h(14.70588235)=-0.0085(14.70588235)^2+0.25(14.70588235)+6,
=-1.838235294+3.676470588+6
=7.838235293 ft
To the nearest foot
= 8 ft
<h3>Solve the equation. Then check your solution. </h3><h3>1.6a = -9.12 </h3>
Answer: b) -5.7
Step-by-step explanation:
<em>To solve this equation for the variable a, we have to clear the variable a, dividing both sides of the equation by the coefficient of the variable a. </em>
a = -9.12/1.6 = -5.7
Answer: b) -5.7

Answer:
(2,6)
Step-by-step explanation:
<u><em>The options of the questions are</em></u>
(0,1) (1,3) (2,6) (3,27)
and the given function is 
we know that
If a ordered pair lie on the graph of the given equation, then the ordered pair must satisfy the given equation
<u><em>Verify each ordered pair</em></u>
case 1) (0,1)
substitute the value of x and the value of y in the linear equation and then compare the results
----> is true
so
The ordered pair lie on the graph of the given equation
case 2) (1,3)
substitute the value of x and the value of y in the linear equation and then compare the results
----> is true
so
The ordered pair lie on the graph of the given equation
case 3) (2,6)
substitute the value of x and the value of y in the linear equation and then compare the results
----> is not true
so
The ordered pair not lie on the graph of the given equation
case 4) (3,27)
substitute the value of x and the value of y in the linear equation and then compare the results
----> is true
so
The ordered pair lie on the graph of the given equation
Answer:
D) 205
Step-by-step explanation:
Given : Cost = 83 - 2 (time taken) + 6 (materials) + 1.1 (marketing cost)
Relationship Equation : y = 83- 2x1+ 6x2 + 1.1x3
Given, time (x1) = 5 , materials (x2) = 4 , marketing cost (x3) = 100
So, putting values, Cost : y = 83 - 2 (5) + 6 (4) + 1.1 (100)
= 83 - 10 + 24 + 110 = 207
The closest to this calculated estimated figure ie 207, is 205.
All the points on the circle
(x+1)^2 + (y-5)^2 = 2
