√18=2√9=2*3=6
A: Explain why her reasoning is incorrect.
B: Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.
Answers
Step-by-step explanation:
√18 = √(2x9) = 3√2. so they pulled the 2 out of the square root incorrectly.
4x4 = 16
5x5 = 25

Given an = 3n-5, what is the common difference?
Answers
Answer:
3
Step-by-step explanation:
A common difference is found in arithmetic sequences. The simplified formula for arithmetic sequences, which is what is used here, is [tex]a_{n}=dn-a_{0}[/tex]. Where d is the common difference and [tex]a_{0}[/tex] is the zeroth term. So, in the given equation 3 must be the common difference.

The perimeter of a rectangle is 90 feet, and the length is 32 feet. What is the width of the rectangle?
A. 26 feet
B. 13 feet
C. 58 feet
D. 15 feet
Answers
2 x (length + width) = perimeter = 32 ft
⇒ length = 16ft - width [1]
length x width = area = 48 sq ft
Using [1] above:
⇒ (16ft - width) x width = 48 sq ft
multiplying out and rearranging:
⇒ width2 - 16 x width + 48 = 0
factorizing:
⇒ (width - 4)x(width - 12) = 0
Thus width = 4 or 12, so using [1] above:
⇒ width = 4ft, length = 16 - 4 = 12ft
or width = 12ft, length = 16 - 12 = 4ft
Convention is that the length is larger than the width, thus rectangle is 12ft long by 4 ft wide.
Answer:
15 ft

What is the Sine Rule?The Law of Sines (also called the Sine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
Triangle is a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry.
As per the given question, the given data as:
A = 63
B = 56
C = 61 (because these angles should add up to 180)
c = 1/2
We know that the Sine Rule,
sin 63 / a = sin 61 / .5
a = 0.51 miles
sin 56 / b = sin 61 / .5
b = 0.47 miles
Therefore, the length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.

By distance formula:
[tex]r = \sqrt{(4 - 1) ^{2} + {(7 - 3)}^{2} } \\ \\ r = \sqrt{ {3}^{2} + {4}^{2} } \\ \\ r = \sqrt{9 + 16} \\ \\ r = \sqrt{25} \\ \\ r = 5[/tex]
Answer:
radius = 5 units
Step-by-step explanation:
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (4, 7)
r = [tex]\sqrt{(4-1)^2+(7-3)^2}[/tex]
= [tex]\sqrt{3^2+4^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= [tex]\sqrt{25}[/tex]
