Answer:
We get the value of constant = 80
Option C is correct answer.
Step-by-step explanation:
We need to find the value of the constant in the equation below.
By putting the value of height and width, we can find the value of constant.
Looking at the graph, x-axis represents width and y-axis represents height.
Taking any point from the graph we can find the value of constant.
Suppose we take the point (4,20)
We will have Width = 4,
Height = 20
Putting values in the given equation, we can find value of constant
So, we get the value of constant = 80
Option C is correct answer.
Answer:
750 minutes
Step-by-step explanation:
Let the number of minutes be represented as x
1 cent = 0.01
Beetle cellular offers cellular phone service for 39.95 a month plus one cent a minute.
$39.95 + 0.01x
Salamander digital offers cellular phone service for 9.95 a month plus five cents a minute.
$9.95 + 0.05x
How many minutes would a person need to use a month for beetle cellular to cost the same as salamander digital?
This is calculated as:
Beetle cellular = Salamander digital
$39.95 + 0.01x = $9.95 + 0.05x
Collect like terms
$39.95 - $9.95 = 0.05x - 0.01x
$30.00 = 0.04x
x = $30.00/0.04
x = 750 minutes
A person need to use 750 minutes a month for beetle cellular to cost the same as salamander digital.
The complete question is
"which statement is true about the extreme value the given quadratic equation? y = -3x^2 + 12x - 33
Oa. The equation has a maximum value with a y coordinate of -27
Ob. The equation has a minimum value with a y coordinate of -21
Oc. the equation has a minimum value with a y coordinate of -27
Od. The equation has a maximum value with a y coordinate of -21"
The quadratic equation has the extreme value at the vertex with a y-coordinate of -21. so, the correct option is D.
<h3>What is a quadratic equation?</h3>
A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The given quadratic equation is
y=-3x^2+12x-33
x = -b/2a
For the given equation the vertex :
x = -12/2(-3) = 2
The value of y at x = 2 is:
y = -3(2²) + 12(2) - 33
y = -12 + 24 - 33
y = -21
The extreme is the maximum for the given equation.
The correct choice is D.
