Answer: statement 2: a square is always a rhombus.
Step-by-step explanation:
A parallelogram does not have all the interior angle as right angle.
Therefore, it does not satisfy property of rectangle.
A square has all sides equal and its diagonals are perpendicular bisector.
Thus, square satisfies all the properties of rhombus .
A rectangle does not have all the sides are equal.
Therefore, it cannot b e a square.
10 is the fourth answer (x-3)^2+(y+4)^2=49
11 is the third answer (x-3)^2+(y-5)^2=64
Answer:
will this work or help ?
Step-by-step explanation:
The given equation governs the height versus time of the object. h(0) = 64, so the ground is considered at h = 0. The question is at what time is h = 0? So, set h = 0 and solve for t.
-16t^2 + 48t + 64 = 0
We can divide both sides of this equation by -16 for simpler numbers. We get
t^2 - 3t - 4 = 0
We can factor this equation:
(t - 4)(t + 1) = 0
So, t = 4 and t = -1 are solutions.
But, time must be positive, so t = -1 makes no sense, so we discard it. This leaves
t = 4 sec.
Answer:
Ethan, 0.89
Step-by-step explanation:
0.89
8 is the tenth, 9 is the hundredths
Here's how you can do that.
Explanation:
The problem tells you that the product of two consecutive odd integers is equal to
783
.
Right from the start, you know that you can get from the smaller number to the bigger number by adding
2
.
You need to add
2
because if you start with an odd number and add
1
, you end up with an even number, which is not supposed to happen here.
odd number
+
1
=
the consecutive even number
×
odd number

2
=

√
So, if you take
x
to be the first number, you can say that
x
+
2
is the second number, which means that you have
x
⋅
(
x
+
2
)
=
783
