Step-by-step explanation:
To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex. Equation in y = ax2 + bx + c form.
Very glad I could help you!1
Answer: A) 4
.2 is less than 4, therefore answer A. is correct
An equation in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
In this case, our y-intercept is 0, so we're left with y = -5x.
-5 is in the place of m, which means -5 is our slope.
The slope of y = -5x is -5.
The correct answer is: [A]: "69° <span>" .

m∠1 = 69° .

Explanation:
_____________________________________________________
180 - (39 + 30) = 180 - 69 = 111. This is the measurement of the third angle in the triangle. Note that all angles in a triangle add up to 180° . All triangles have 3 (three) sides and 3 (three) angles.
To find m∠1 :
_____________________________________________________
The only single angle that exists that is supplementary to ∠1 is 69.
So: m∠1 = 180 - 111 = 69 . (Note: since all angles on a straight line are supplementary angles; and supplementary angles add up to 180° .
_______________________________________________________
The answer is: 69° .
m∠1 = 69° .

The pond will be full by the end of the day in 93 days.
<h3>Linear system</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The pond can hold 400 water liters.
y = 3.915(1.106)x is an expression.
<h3>To find </h3>
The pond will be full by the end of the day.
<h3>How many days it will take?</h3>
Let x be the day and y be the hold of water.
When pond can hold 400 liters of water the x will be
400 = 3.915×1.106x
400 = 4.33 x
x = 92.37 ≈ 93
Thus, the pond will be full by the end of the day in 93 days.
