Answer:

A & D

Step-by-step explanation:

The parabola opens up, so the minimum value of y is at the point (1, -2) and the graph passes thru the x-axis at 3 and -1, so those are the x-intercepts.

The axis of symmetry is x = 1, not y = -2 and the graph never has a maximum value. Parabolas that open up never have a maximum value.

What is the area of △ABC ? Enter your answer, as a decimal, in the box. Round only your final answer to the nearest tenth. units

fiasKO [112]

Answer: $36.1\ units^2$

Step-by-step explanation:

You need to use the SAS area formula. This is:

$A=\frac{a*b*sin(\alpha)}{2}$

Given the triangle ABC, you know that:

$a=AC=10\ units\\b=BC=17\ units\\\alpha=\angle ABC=25.1\°$

Therefore, substituting these values into the formula, you get that the area of the triangle ABC is:

$A=\frac{(10\ units)(17\ units)*sin(25.1\°)}{2}\\\\A=36.1\ units^2$
