The answer is b, it would root 2x² which would simplify into x root 2
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
U have to go by the area
A = LW
A = (20)(30) = 600 ft^2
A = (25)(25) = 625 ft^2
A = (35)(15) = 525 ft^2
A = (40)(10) = 400 ft^2
I believe it would be the : 25 ft by 25 ft
Answer:
The last one
Step-by-step explanation:
A scalene triangle has no similarities between the angles or the sides
In the shown triangle none of the sides are similar and none of the angles are congruent therefore this is a scalene triangle
Reasons why its not the other answers
- This is not an acute triangle. In order for it to be an acute triangle all of the angles have to have a measure less than 90 degrees. There is an angle with a measure of 120 degrees the triangle is not an acute triangle
- This triangle is not an isosceles triangle. In order for it to be an isosceles triangles it has to have at least one congruent side. None of the sides are congruent therefore it is not an isosceles triangle
- This is not a right triangle. In order for it to be a right triangle one of the angles has to have a measure of 90 degrees. Because none of the angles measure 90 degrees it is not a right triangle
In conclusion the answer would be that this triangle is a scalene triangle
Let
x------> Jorge's age
y-----> Jorge's brother's age
we know that
-----> equation A
-----> inequality B
substitute the equation A in the inequality B
The minimum value of y is equal to years
therefore
<u>the answer is</u>
the youngest age Jorge's brother is years
