Answer:
54.67 cm²
Step-by-step explanation:
Given that the two sides of Δ ABC are 8.2 cm and 13.5 cm and the angle included by those sides is 81°.
Let, b = 8.2 cm and c = 13.5 cm and ∠ A = 81°
Hence, area of triangle ABC, Δ =
⇒ Δ =
⇒ Δ =
⇒ Δ = 54.67 cm² (Answer)
Answer:
y - 4= 3/2 (x-4)
Step-by-step explanation:
The roots of
are 0 (multiplicity 2), -3 (multiplicity 1),
(multiplicity 1) and
(multiplicity 1).
The characteristics of the polynomial can be derived from algebraic techniques. Roots and multiplicity can be found by <em>factoring</em> the polynomial. The multiplicity is represented by a power binomial of the form:
(1)
Where
is the grade of the polynomial.
Now we proceed to factor the formula:



Please notice that
have two complex roots.

The roots of
are 0 (multiplicity 2), -3 (multiplicity 1),
(multiplicity 1) and
(multiplicity 1).

Answer:
√19 or 4.36
Step-by-step explanation:
Since one leg is missing, you need to use Pythagorean theorem for this.
The hypotenuse is known so,
c² - a² = b²
c = 10
a = 9
b = ?
10² - 9² = b²
100 - 81 = b²
19 = b²
b = √19
