Use the Pythagorean Theorem to solve this question.
I use the ^ to tell that it is squared
so 9 squared +3 squared =x squared
9^2+3^2=x^2
x^2= radical 90
x ≈ 9.5 feet
Answer:
<u>Option 4: (3,5)</u>
Step-by-step explanation:
(x - 3)(x - 5) < 0
Therefore, the intervals that must be tested are x < 3 , 3<x<5 and x>5
Test of the interval x<3⇒ Let x = 0 ⇒ (-3)(-5) = 15 > 0
Test of the interval 3<x<5 ⇒ Let x = 4 ⇒ (4-3)(4-5) = (1)(-1) = -1 < 0
Test of the interval x>5⇒ Let x = 6 ⇒ (6-3)(6-5) = (3)(1) = 3 > 0
So, the solution set for the quadratic inequality is the interval 3<x<5
Or x ∈ (3,5)
See the attached figure.
The answer is <u>option 4</u>
B. Accuracy is if it's right or not. Precision is how many decimal places it goes out to. So it is precise but not accurate.
One hundred thousand, or in this case, four hundred thousand.
$10-$5.42=$4.58
:.each bag of chips =$4.58/2=$2.29
