Answer:
51.9914 or 52 hrs.
Step-by-step explanation:
-0.0006h²+0.016+0.79 (divide each term by -0.0006)
=h²-(80/3)h-(3950/3)
Using the quadratic formula
((80/3)+sqrt((-80/3)^2-4(1)(-3950/3)))/2(1)
= 103.9828/2
=52.9914
Aprroximation: 51.9914 or 52 hrs.
Exact: ((80/3)+sqrt(53800/3))/2
Answer:
If a shape is a square, then it is a quadrilateral
Step-by-step explanation:
Quadrilateral means four sided shape, so automatically, because a square has 4 sides, you know it is a quadrilateral. But not all quadrilaterals are a square, you could have a rectangle which is four sides so you know that this statement is wrong "If a shape is a quadrilateral, then it is a square." Therefore, the answer is "If a shape is a square, then it is a quadrilateral
Answer:
The answer is "Study 2"
Step-by-step explanation:
In Study 2:

We are given first equation y=
x+11.
Second equation is -3x + 7y = 13.
Part A: We need to convert that second equation in slope-intercept form y=mx+b.
In order to convert it in slope-intercept form, we need to isolate it for y.
-3x + 7y = 13
Adding 3x on both sides, we get
-3x+3x + 7y = 3x+13
7y = 3x +13.
Dividing both sides by 7, we get
7y/7 = 3x/7 +13/7.
<h3>y= 3/7 x + 13/7.</h3>
Slope for first equation y=3/7 x +11 is 3/7 and slope of second equation y= 3/7 x + 13/7 is also 3/7.
Slopes are same for both equations.
<h3>Part B: Therefore, lines are parallel due to equal slopes.</h3>
To get this you need to find what minus 2 equals -2. The answer for w is -1 because -1 - 2 = -3.
