The first statement is false. A square DOES have 4 right angles.
9514 1404 393
Answer:
B, D, E
Step-by-step explanation:
All of the acute angles are congruent to each other. All of the obtuse angles are supplementary to them and are also congruent to each other. Angles 2, 3, 6, 7 are supplementary to angle 4. The ones on the list of choices are ...
∠2, ∠6, ∠7
Answer: Choice A
The axis of symmetry for the function is x = 0.
===========================================================
Explanation:
The vertex is on the axis of symmetry. Since the vertex is on the y axis, this means the y axis itself is the axis of symmetry. The y axis is represented by the equation x = 0. Every point on the y axis has an x coordinate of 0. Example points are (0,2) and (0,5).
This parabola may have 0 roots, 1 root, or 2 roots.
Answer:
Approximate only
Step-by-step explanation:
the perfect square smaller than 1.4 is 1, because 
Take the difference between the two, 1.4 -1 = 0.4
Put the whole with 1. the part will be as follow:
Note: just approximate!! with calculator, it is 1.18321

Answer:</h2>
4.82 × 10⁻⁴
<h3>
Explanation:</h3>
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
