In 1964, paleontologists discovered the bones of a new species of dinosaur. The age of the dinosaur was estimated using potassium-40 dating of rocks surrounding the bones. Analysis of these rocks indicated that 88.7% of the original amount of the potassium-40 was still present. The decay model for potassium-40 is Upper A equals Upper A 0 e Superscript negative 0.52912 t Baseline comma where t is in billions of years. Let Upper A equals 0.887 Upper A 0 in this decay model and estimate the age of the bones of the dinosaur.

-2x(x-3)=-11 (correct two decimal place)
Answers
-2x(x) -2x(-3) = -11
-2x² + 6x = - 11
-2x² + 6x + 11 = 0
Let us use the quadratic formula in solving for the value of x.
-2x² + 6x + 11 = 0
a = -2 ; b = 6 ; c = 11
x = (-b + √b² -4ac) ÷ 2a
x = (-6 + √6² - 4(-2)(11)) ÷ 2(-2)
x = (-6 + √36 + 88) ÷ -4
x = (-6 + √124) ÷ -4
x = (-6 + 11.14) ÷ -4
x = 5.14 ÷ -4
x = -1.285 or -1.29
x = (-6 - 11.14) ÷ -4
x = -17.14 ÷ -4
x = 4.285 or 4.29

Since the circumference is equivalent to 7.38 cm, the formula can be displayed as follows:
7.38 cm = 2πr
r = 7.38cm/2π
r= 1.1751592 cm
diameter = 2r
= 2.3503184 cm or approximately 2.35 cm

Answer:
The measure of the vertex angle of the next isosceles triangle is 10°
Step-by-step explanation:
The given information are;
The first isosceles triangle; Base angles = 89°, vertex angle = 2°
The second isosceles triangle; Base angles = 88°, vertex angle = 4°
The third isosceles triangle; Base angles = 87°, vertex angle = 6°
The fourth isosceles triangle; Base angles = 86°, vertex angle = 8°
The vertices of the isosceles triangles form a arithmetic projection, with a common difference of 2°
Therefore, the vertex for next isosceles triangle = 8° + 2° = 10°
The base angles are derived from the sum of interior angles of a triangle which is 180°
Which gives;
2 × Base angles + Vertex angle = 180°
2 × Base angles + 10° = 180°
2 × Base angles = 180° - 10° = 170°
Base angles = 170°/2 = 85°
Base angles of the fifth isosceles triangle = 85°
From which we have;
The fifth isosceles triangle; Base angles = 85°, vertex angle = 10°
The measure of the vertex angle of the next (fifth) isosceles triangle = 10°
