The area of a triangle can be calculated as half the product of base length and height. We want the area to be no greater than 10 in².
a) (1/2)(4)(2x-3) ≤ 10
b) 4x -6 ≤ 10 . . . . . simplify
... 4x ≤ 16 . . . . . . . .add 6
... x ≤ 4 . . . . . . . . . divide by the coefficient of x
c) The maximum value of (2x -3) in is (2·4 -3) in = 5 in.
The triangle should be no more than 5 in high to have an area less than 10 in².
Answer:
$82,000
$66,000 + $4000t
Step-by-step explanation:
Initial annual salary = $66,000
Salary raise per year = $4000
Salary earned after 4 years :
Initial salary + (raise per year * number of years)
$66,000 + ($4000 * 4)
$66,000 + $16,000
= $82,000
Salart after t years :
Initial salary + (raise per year * number of years)
$66,000 +.($4000 * t)
$66,000 + $4000t
Answer:
s=5
Step-by-step explanation:
6s-4=16+2s
6s=20+2s
4s=20
s=5
Answer:
B. 30
Step-by-step explanation:
First, you multiply by 5 from both sides of equation.
Simplify, to find the answer.
, which is our answer.
(x - 8)^2 = 144
take the sq rt of both sides
x - 8 = 12
x = 12 + 8
x = 20
20 feet by 20 feet
