Answer:
Step-by-step explanation:
This represents an arithmetic progression with the first term of a = 15 and common difference of d = 3.
<u>The tenth row is the 10th term:</u>
<u>The row 10 has:</u>
- a₁₀ = 15 + 9*3 = 15 + 27 = 42 seats
Answer:
Step-by-step explanation:
x²+x²=14²
2x²=196
x²=196/2=98
x=7√2 ft
Answer:
Step-by-step explanation:
Given: 
Factorizing the numerator and the denominator, we have:
18
- 45q + 25 = 18 - 30q - 15q + 25
= (3q - 5)(6q - 5)
and
9 - 25 = (3q - 5)(3q + 5)
So that,
= 
=
Therefore,
=
Sample Answer: No, Ingrid is incorrect. The initial value in the scenario is 170 feet, which represents the y − intercept. Receding 4 feet in the scenario represents the rate of change, which is the slope. In slope-intercept form, y = mx + b, where m represents slope and b represents the y−intercept, so the correct equation is y = −4x + 170.
