Answer:
x^2 - 2x + 1
Step-by-step explanation:
(x-1)^2 = (x-1)(x-1)
= x^2 - x - x + 1
= x^2 - 2x + 1
Answer:The cost to ship one ounce is $0.48 per ounce
Step-by-step explanation:
The total weight of the package that Julia shipped is 9.5 ounces. Julia pays $4.56 to ship a package that weighs 9.5 ounces. The cost to ship one ounce would be
4.56/9.5 = $0.48 per ounce
Hey there!☺
We will need to factor . In order to that, we will have to start grouping.
Hope this helps!
X = 4
3 divided by 4 = .75
Answer:
x = 5√3; y = 5
Step-by-step explanation:
Finding y: The sine function links the 30° angle, the 10 unit hypotenuse and the side opposite the angle, y:
sin 30° = 1/2 = y/10
Solve the equation of ratios
1 y
-- = ----- using cross-multiplication first: 2y = 10 → y = 5
2 10
We can now find x either by using a similar approach and the cosine function or by using the Pythagorean Theorem:
x² + y² = 10² = 100 → x² = 100 - y² = 100 - 5² = 75
If x² = 75, then x = ±√75 = ± (√25)·(√3) → ±5√3
Since lengths are always positive, take x = 5√3 as the answer.
