Given
Write the next three terms of the arithmetic sequence. -13, -8, -3, 2, _, _, _
Procedure
-13+5=-8
-8+5=-3
-3+5=2
2+5=7
7+5=12
12+5=17
The sequence is -13, -8, -3, 2, 7, 12, 17
Answer:
749 ft
Step-by-step explanation:
It's a right-angle triangle so you can use trig ratios
750 feet
tan(59) = opposite/adjacent
tan(59l = X/450
X = 450×tan(59)
X = 748.9 ft
X = 749 ft (correct to 3 sf)
Answer:
1
Step-by-step explanation:
Let the number be x
x² + 2x = 3
x² + 2x - 3 = 0
Product = -3
Sum =2
Factors = 3 * (-1)
x² + 3x - x - 3 = 0
x*(x+3) - (x + 3) = 0
(x + 3)(x - 1) = 0
Ignore x + 3 because the number is a positive number
x - 1 = 0
x = 1
The number is 1
