Answer:
-4
+3
12
-0.5, 12.25
x = -0.5
Step-by-step explanation:
The x intercepts are the values of x when y = 0 ie the roots of the equation
or
We can re-write the above as:
(x+4) (x-3) = 0
This gives the two roots as x = -4 and x = +3. Leftmost (smallest) root is -4 and rightmost(largest) root is +3
y intercept is when x = 0. Plugging into the original equation, y value at x = 0 is 12
Vertex x value is given by the formula -b/2a where a is the coefficient of x^2 and b the coefficient of x
Here a = -1, b= -1 so vertex x value = - (-1)/(-1).2 = - 1/2 = -0.5
Plugging this value of x into the original function gives the vertex y value
The line of symmetry is the vertical line corresponding to the vertex x value so line of symmetry is at x = -0.5
The graph of the quadratic function shows these values

Answer:
Among the five statements,statement 1 and 4 are true for the circle shown.
Step-by-step explanation:
Given:
An image is attached here.
A circle with radius = 15.4 m
We ave to find the diameter,circumference and relationship between the two.
Formula to be used:
⇒ Diameter of a circle = 2r
⇒ Circumference = 2πr
Lets find the values.
- Diameter =
m - Circumference =
m - Relationship =
We can say that a little more than 3 diameters could be wrapped around the circle.
From the drop down our choices are.
- The diameter of the circle is 30.8 m.
- The approximate circumference of the circle
,rounded to the nearest tenth is 96.7 m.
Option 1 and 4 are the right choices.

Answer:
Yes, the bill is absolutely accurate
Step-by-step explanation:
Cost of materials= $ 678.12
Final bill amount(given)=$1206.12
Rate= $32 per hour for 16.5 hrs
Total amount for 32 hrs = time * rate = 16.5* 32=$528
Therefore, by the problem ,
<em>Cost of materials+ Total amount for 32 hrs = Final bill amount</em>
= 678.12+ 528
=1206.12
<u>Therefore , the final bill amount is 100% accurate as it completely matches with the given bill amount</u>
