Answer:
You selected the correct answer: {x | x <<em> </em>-4 or x > 2}
Step-by-step explanation:
5(x - 2)(x + 4) > 0
Use FOIL method to expand (x - 2)(x + 4):
> 0
Distribute 5 into
> 0
Divide all terms by 5 from both sides of the inequality:
Factor the trinomial:
(x + 4) ( x - 2) > 0
x < -4 or x > -2
Therefore, the solution set to the inequality is {x | x < -4 or x > 2}
<em>Interval notation: </em>(-∞, -4) ∪ (2, ∞)
Tan(58)=10/x
x=10/tan(58)
x= 6.2
Answer:
This approach often yields much more accurate results than the trapezoidal rule does. Again we divide the area under the curve into n equal parts, but for this rule n must be an even number because we're estimating the areas of regions of width 2Δx.
Answer:
$38.48
Step-by-step explanation:
To find the sales tax you add 4% to 100%, which is 104%
Then you turn that into a fraction, which is 104/100
Then you multiply 104/100 by 37
You should get 38.48
Hope this helps! : )
