What is the equation written in vertex form of a parabola with a vertex of (3,6) that passes
through point (4,4)?
Answer:
f(x) = -2(x - 3)² + 6Step-by-step explanation:
The vertex form of an equation of the parabola:
f(x) = a(x - h)² + k
the vertex is (3, 6) ⇒ h = 3, k = 6
so:
f(x) = a(x - 3)² + 6
The parabola goes through the point (4, 4) ⇒ x=4, f(x)=4
4 = a(4 - 3)² + 6
4 = a(1)² + 6
-6 -6
- 2 = a
It means the equation of the parabola in vertex form:
f(x) = -2(x - 3)² + 6

The triangle below has been reduced by a scale of 0.4. A large triangle has a base of 30 centimeters and height of 10 centimeters. A smaller triangle does not have dimensions provided. What is the area of the reduced triangle? 24 centimeters squared 60 centimeters squared 75 centimeters squared 375 centimeters squared
Answer:
24 centimeters squared(cm²)
Step-by-step explanation:
The triangle below has been reduced by a scale of 0.4.
A large triangle has a base of 30 centimeters and height of 10 centimeters.
Hence, reducing the large triangle by the given scale ratio, we have :
Height = 10cm × 0.4 = 4cm
Base = 30cm × 0.4 = 12 cm
Hence, the area of the smaller triangle
= Area = 1/2 × Base × Height
Height = 4 cm
Base = 12 cm
Area = 1/2 × 4 × 12
= 24 cm²

A

A clothes hanger is in the shape on an isosceles triangle. If the hanger is 70° wide what are the base angles?
Answer:
55°
Step-by-step explanation:
Given parameters:
Angles in the triangle;
70°, X° and X°
The triangle is an isosceles triangle;
In all triangles, the sum of the interior angles is 180°
So;
70° + X° + X° = 180°
70° + 2X° = 180°
2X° = 180° - 70°
2X° = 110°
X° = [tex]\frac{110}{2}[/tex] = 55°
