Answer:
$20,800
Step-by-step explanation:
There are 52 weeks in a year, therefore, do 100 x 52 = $5,200
You earn $5,200 a year, for 4 years so do 5,200 x 4 = $20,800
Triangle: original side is 5 units long, copy side is 1 unit long
Scale = copy side/ original side = 1/5
Scale = 1/5
Second image:
Side of A is 6 units long
Side of B is 18 units long
Scale = B side / A side = 18/6 = 3
Scale = 3
Answer:
9.25
Step-by-step explanation:
No problem..
Answer:
Missing side length = 54
Step-by-step explanation:
If both the triangles given in the picture are similar their corresponding sides will be proportional.
By applying this rule in the given similar triangles,
Therefore, missing side length =

Answer: Vertex = (0, 3) 2nd point = (1, 2)
<u>Step-by-step explanation:</u>
f(x) = -x² + 3 → f(x) = a(x - 0)² + 3
If you use transformations with the parent graph f(x) = x², the transformation is reflected over the x-axis and shifted 3 units up.
If you use the vertex formula: f(x) = a(x - h)² + k
- the vertex is (0, 3) ← PLOT THIS COORDINATE
- "a" is negative, so the parabola points downward
This equation does not factor over the rational numbers, so find a second point by choosing an x-value and plugging it into the given equation to solve for y. <em>I chose x = 1</em>
f(1) = -(1)² + 3
= -1 + 3
= 2
So, an additional point is (1, 2) ← PLOT THIS COORDINATE
