Step-by-step explanation:
It’s just basic substitution
Hope this helps!
I remember CUP -- concave up positive. Here we have a leading coefficient that's negative, so the cup is upside down, the parabola opens down, an arch not a bowl.
Answer:
Perimeter=22 m
Step-by-step explanation:
Perimeter Of A Figure
Perimeter is the distance measured around a shape. If the figure is line-shaped, the perimeter can be obtained by adding the individual lengths of each segment around the shape.
The figure shown is surrounded by line segments. We only have to add them all to find the perimeter. But we don't need each individual length to do so. We may notice the following (given all angles are right):
The sum of HG+FE+DC equals AB. So the upper and lower lengths are twice AB, or equivalently: 2*7 1/2 m =15 m
It can also be noted that AH+GF=BC+DE=2 1/4+1 1/4 = 3 1/2 m. It means that the two lateral lengths are twice this value: 2* 3 1/2 = 7 m
Thus, the total perimeter is 15 m + 7 m = 22 m
Answer:
2. quadrant 4
3. quadrant 2
4. quadrant 3
Step-by-step explanation:
You can refer to the picture.
2. Since 
less than 0 which means is negative, 
less than 0 which means is negative.
So, the angle lies in quadrant 4 (Cos quadrant)
3. Since less than 0 which means is negative, 
less than 0 which means is negative.
So, the angle lies in quadrant 2 (Sin quadrant)
4. Since more than 0 which means is positive, less than 0 which means is negative.
So, the angle lies in quadrant 3 (tan quadrant)
