Complete the table. Circle the letter of the equation that relates the age
of Arianna, y, to the age of Javier, x.
Answers
Answer:
Step-by-step explanation:
Arianna will always be 3 years older than Javier no matter how old he gets.
The table is given below.
The equation that relates the age of Arianna y to the age of Javier x is
y = x + 3
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
We can use the given information to complete the table as follows:
Javier(x) Arianna (y)
2 5
3 6
8 11
20 23
Now,
The equation that relates the age of Arianna, y, to the age of Javier, x.
We have,
y = mx + b, where m is the slope and b is the y-intercept.
We can use the first two points (2, 5) and (3, 6) to find the slope.
m = (6 - 5)/(3 - 2)
m = 1
Now,
The y-intercept,
(2, 5) = (x, y)
y = mx + b
5 = 1(2) + b
b = 3
Therefore,
The equation that relates the age of Arianna y to the age of Javier x is
y = x + 3

find the length of the bold arc. Round your answer to the nearest tenth.
Answers
Answer:
The length of the bold arc is approximately 13.4 mi
Step-by-step explanation:
The radius of the circle having the arc, r = 17 mi
Therefore, the circumference of the circle, 'C', is given as follows;
C = 2·π·r
∴ C = 2×π×17 = 34·π
The angle subtended by the arc = 45°
The sum of the angles at the center of the circle = 360°
By similarity, the ratio of the length of the bold arc to the circumference of the circle = The ratio of the angle subtended by the arc to the sum of the angles at the center of the circle
Mathematically, we have;
[tex]\dfrac{The \ arc \ length}{C} = \dfrac{\theta}{360^{\circ}}[/tex]
Therefore, we get;
[tex]\dfrac{The \ arc \ length}{34 \cdot \pi} = \dfrac{45 ^{\circ}}{360 ^{\circ}} = \dfrac{1}{8}[/tex]
[tex]{The \ arc \ length}{} = \dfrac{1}{8} \times 34 \cdot \pi = 4.25 \cdot \pi[/tex]
The length of the bold arc = 4.25·π mi ≈ 13.4 mi (by rounding off the answer to the nearest tenth).

Answer: [tex]\sqrt{5} + \sqrt{3} + 10 + 2\sqrt{15}[/tex]
Step-by-step explanation:
[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} }[/tex]
You need to multiply by the conjugate
To find the conjugate, first remember:
(a+b)(a-b) = a^2 - b^2 (if a and b are sqrts, this will eliminate the square roots, rationalizing the denominator)
You have √5 - √3 as the denominator
You should multiply by √5 + √3
(This will eliminate the sqrts)
Remember to multiply both the numerator and denominator
[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } = \frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } * \frac{\sqrt{5}+\sqrt{3} }{\sqrt{5}+\sqrt{3}}[/tex]
Now simplify
[tex]\frac{2+4\sqrt{5} }{\sqrt{5}-\sqrt{3} } * \frac{\sqrt{5}+\sqrt{3} }{\sqrt{5}+\sqrt{3}} = \frac{(2+4\sqrt{5})(\sqrt{5}+\sqrt{3})}{(\sqrt{5}-\sqrt{3})(\sqrt{5}+\sqrt{3})} = \frac{2\sqrt{5}+2\sqrt{3}+20+4\sqrt{15}}{5-3} = \sqrt{5} + \sqrt{3} + 10 + 2\sqrt{15}[/tex]

A rectangle with a width of w and a length of ? has a perimeter greater than 100.
Here is a graph that represents this situation.
Write an inequality that represents this situation.
Answers
Answer:
Let L = length
Let w = width
Perimeter = 2L + 2w
L = 100
Perimeter > 400
2(100) + 2w > 400
200 + 2w > 400 is the inequality
Subtract 200 on both sides of inequality.
2w > 200
w > 100
The width is at least 100 centimeters
The inequality that describes the perimeter of a rectangle is greater than 100 is 2(l + w) > 100.
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
Given, A rectangle with a width of w and a length of l has a perimeter greater than 100.
We know the perimeter of a rectangle is 2(l + w).
∴ The perimeter of this rectangle is 2(l + w) > 100.
