Emma’s statement makes sense and Charles’ doesn’t, bcuz when you say 0.75 it should be 75 tenths, because it’s less than a whole number, but charles said 7 and 5 tenths, if it’s 7 and 5 tenths, it would be 7.5.
The discriminant can be determined from the number of roots of the graph.
If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.
Since the given graph has no real root, i.e. it does not cross x-axis at any point, so we can say that the discriminant of the given function is negative.
So the answer to this question is option C
Answer:
3bat + 3b² - 6a²t²
Step-by-step explanation:
First you have to expand it to get;
3b(b - at) + 6at(b - at)
Then you can now multiply.
3b² - 3bat + 6bat - 6at²
Group like terms
6bat - 3bat + 3b² -6at²
3bat + 3b² - 6a²t²
1. the perimeter of a square is always 4 * side, so = 4*31/8 = 31/2 or 15 and 1/2
2. area of a square is always the side multiplied by each other, so: 9/2 * 9/2 = 81/4 or 20 and 1/4
Answer:
Step-by-step explanation:
<h3>Question 1</h3>
<u>Prove that The two triangles are congruent</u>
- ∠ABD ≅ ∠BDC - given
- BD ≅ DB - reflexive property
- ∠ADB ≅ ∠CBD - given
- ΔABD ≅ ΔCDB - ASA postulate
<u>Find the measure of angle C</u>
- ∠A ≅ ∠C - Corresponding parts of congruent triangles
- m∠C = m∠A = 180° - (62° + 70°) = 180° - 132° = 48°
<h3>Question 2</h3>
<u>Given </u>
Opposite angles are corresponding to the sides.
Therefore the angles opposite to congruent sides are also congruent:
