Answer:
a) BD = 5
b) FD = 13
Step-by-step explanation:
For both questions we follow pythagoras therom.
For the first one we do 3^2 +4^2 = 25 and then we root this answer to 5
For the second we have to find the base of GD in order to find FD. GD will be 4^2+12^2 which equals to 160 and then you root.
Finally, we can find FD which is sqaure root of 160^2 + 3^2 = 169. The square root of 169 is 13. Answer is 13.
Answer:
1st graph.
Step-by-step explanation:
The function y = -x² + 5, reflects the 1st graphic.
Reasoning:
- If we make x equal to 0, y=5, it meas the parabole crosses y-axis at 5.
- In every quadratic function, if the value of x is negative, the parabole goes downwards.
Answer:
< (less than)
Step-by-step explanation:
since abs value changes it to positive it would be
5 and 9
5 < 9
I switched both sides of the equation in the very beginning so it would be easier to solve.
42•48=2,016. Hope this helped!
