Answer:
mi clase favorita es (put In the name of the class)
El or la maestra (if man maestro or woman maestra) name the teacher of your favorite class.
In then asks what is in front, behind, to the left, and right of you in your favorite class
Step-by-step explanation: you will need to pick your favorite class. Mi clase favorita es matemáticas. El maestro es Señor Joe. Enfrente de mí es otro estudiante. Detrás de mí es una ventana. Al la izquierda y derecha son libros de matemáticas. This is an example.
a. The graph is concave up in the interval 0 ≤ x ≤ +∞
b. The graph is concave down in the interval -∞ ≤ x ≤ 0
To answer the question, we need to know what intervals are
<h3>What are intervals?</h3>
Intervals are range of values in which a function is valid. It can either be the range of values of input or output of the function.
<h3>a. Interval where the graph is concave up</h3>
From the graph, we see that the function is concave up in the interval 0 ≤ x ≤ +∞
So, the graph is concave up in the interval 0 ≤ x ≤ +∞
<h3>b. Interval where the graph is concave down</h3>
From the graph, we see that the function is concave down in the interval -∞ ≤ x ≤ 0
So, the graph is concave down in the interval -∞ ≤ x ≤ 0

Answer:
-6
Step-by-step explanation:
Answer:
207 cm
Step-by-step explanation:
Because ΔPQR ≅ΔSTU and the longest side in the ΔPQR is RP then the longest side in ΔSTU must be SU = 92 cm
Perimeter of triangle PQR is
P(ΔPQR) = 36+48+24 = 108 cm
Because the triangles are are similar their sides are in proportion.
But how much bigger did the second triangle get?...is (92/48) times bigger
P(ΔSTU) = 180*(92/48) = 207 cm
...you can also use proportions to find each side and then find the perimeter
TU = 24*92 /48 = 46
TS = 36*92/48 = 69
SU = 92
P(ΔSTU) = 92+69+46 =207 cm
*the triangles are not drawn to scale
