Answer: slope=3 Y=1
Step-by-step explanation:
Step 1: Find two points (0,2) & (1,5)
Step2: Y2-Y1 over X2-X1
5-2. 3
——- = ——
1-0. 1
(1,3)
Answer:
Gọi AH là đường cao kẻ từ A đến BC
Xét tam giác AHC vuông tại H
Suy ra AH = HC. cotA= 9.cot35° = 12,9
Xét tam giác AHB vuông tại H
Suy ra BH = AH.tanA = 12,9.tan61°=23,37
Ta có BC= HC+ HB= 9+23,27 =32,27
Diện tích tam giác ABC = 1/2 × AH ×BC= 1/2 ×12,9×32,27=208,1415

Answer:
<h2>the slope m = 3</h2>
Step-by-step explanation:
Look at the picture.
The formula of a slope:

From the graph we have the points (0, 4) and (-2, -2). Substitute:

The scenario is wrong. according to the three other tools, the hot air balloon would be increasing in altitude, not descending.
