Answer:
B
Step-by-step explanation:
Since the triangle has 2 equal base angles (45 degrees) and 1 angle is 90 degrees, the triangle is an isosceles right triangle.
We let a be the length of one side of the right angle, so the length of the other side is also a. Applying the Pythagorean theorem we have a^2 + a^2 =14^2 => a=
We have the area of an equilateral triangle 1/2 the product of the lengths of the 2 sides of the right angle. S=1/2*
=49
Answer:
A
Step-by-step explanation:
y = (-2/5)x + 1
By inspection of the equation, the slope of the line is -2/5 and the y-intercept is 1.
Therefore, we can immediately discount option B and D, as their y-intercepts are NOT 1.
Find the point where the line crosses the x-axis by setting the equation to 0 and solving for x:
0 = (-2/5)x + 1
⇒ -1 = (-2/5)x
⇒ -5 = -2x
⇒ x = 5/2
Therefore, the line of the function intersects the x-axis at x = 5/2 = 2.5
From inspection of the graphs, the line in option A intersects the x-axis at 2.5. Therefore, this is the correct graph.
Answer:
we have
using a graph tool
see the attached figure
the domain of the function is all real numbers------> the interval is (-∞,∞)
the range of the function is --------------------------------> the interval (-∞,9]
therefore
the answer is
The range of the function is all real numbers less than or equal to 9
