Answer:
D.
Step-by-step explanation:
7500 * 6% = 450 which would just barely be enough to get paid the same amount as the fixed salary.
hopefully this helps
Step-by-step explanation:
Notice that KM = 0.5BC, KL = 0.5AC
and ML = 0.5AB. Therefore the perimeter of triangle KLM is half of the perimeter of triangle ABC. => 0.5 * 24cm = 12cm.
Each of the 3 purple triangles have perimeters which are 1/4 of the perimeter of triangle ABC. (Their vertices are midpoints of midpoints => 1/2 * 1/2)
Perimeter of 3 small purple triangles
= 3 * [24cm * (1/4)]
= 3 * 6cm = 18cm.
Hence Total perimeter of shaded parts
= 12cm + 18cm = 30cm.
Answer:
(-5,-28)
Step-by-step explanation:
Given
Required
Find the coordinates of the vertex
Given that the function is a quadratic function;
The general form of a quadratic function is
By comparison;
To calculate the coordinates of the vertex;
we start by calculating the x-coordinate;
Substitute 10 for b and 1 for a
Substitute in the given function;
<em>Hence, the coordinates of the vertex is (-5,-28)</em>
As it is shown in the figure, the length of the square's side s is also the length of the circle's diameter d:
s = d = 28 in.
• Computing the area of the square:
A₁ = s²
A₁ = 28²
A₁ = 28 × 28
A₁ = 784 in² ✔
• Computing the area of the circle:
A₂ = π × r²
A₂ = π × (d/2)²
A₂ = π × (28/2)²
A₂ = π × 14²
A₂ ≈ 3.14 × 14 × 14
A₂ ≈ 615.44 in² ✔
—————
• The area of the shaded portion is equal to the difference between the area of the square and the area of circle:
A = A₁ – A₂
A ≈ 784 – 615.44
A ≈ 168.56 in² <——— this is the answer (1st option).
I hope this helps. =)
