What is the area and perimeter of the equilateral triangle? Round your final answer to the nearest tenth of a square unit.
Answers
Answer:
In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4. 2 ways to find the area of a triangle using Pythagorean Theorem? 1. Using Pythagorean theorem. The basic formula for triangle area is side a (base) times the height h , divided by 2: area = (a * h) / 2 2.Using trigonometry. Let's start from the trigonometric triangle area formula: area = (1/2) * a * b * sin(γ) , where γ is the angle between sides.

Remark
I hope you have some idea how to make your calculator use logs. This problem is impossible without being able to take the log of each side.
Solution
log(8)^x > log 24 Logs lets you bring down x and multiply it by log24
x log 8 > log 24 Be careful what you do next. Don't use log 3
x > log(24)/log(8)
x > 1.3802/0.9031
x>1.5284
As wrong as this may look, it is correct.
Check it
8^1.5284 = 24.00395
The difference is that 1.5284 has been rounded just a slight bit.

A carpet store advertises 16 yards of carpeting for $300, which includes the $60 installation fee in the price. Let x represents the cost of one square yard of carpet. What is the price for one square yard of carpet?
Answers
Answer:one yard costs $15 (x=15)
Step-by-step explanation:
300-60=240. So, 16 yards=$240
16x=240
240/16=15
X=15 (one yard costs $15)
The price for one square yard of carpet is $15.
Given that,
A carpet store advertises 16 yards of carpeting for $300, which includes the $60 installation fee in the price. Let x represents the cost of one square yard of carpet.Based on the above information, the calculation is as follows:
[tex]= (\$300 - \$60) \div 16[/tex]
= $15

a plane departs an airport and mistakenly travels due west at 500mph for 30 minutes. the pilot realizes that the correct destination (airport b) was actually 600 miles away at a bearing of 60 degrees west from airport a. how far is the airplane from its original destination now?
Answers
Answer:
403 miles
Step-by-step explanation:
500 mph is 500 miles per hour
30 minuites is half an hour, so that is 250 miles west
60 degrees west, 600 miles away
so it is a triagle of 30 60 and 90.
600 is the hypotenuse of the 30 60 90 triangle
we need to find the height of the 30 60 90 triangle
using the special rule, the height is 300
the length of the 30 60 90 triangle is 300rt3
so 300rt3 - 250 is the length of another triangle.
height is still 300
hypotenuse is the distance of the actual area minus the plane's current position
(300^2 + (300rt3-250)^2)^1/2 is about 403.351433

The terms in Pattern B are one half the value of the corresponding terms in Pattern A. The terms in Pattern A are one half the value of the corresponding terms in Pattern B. The rule for Pattern B is "multiply by 4." The rule for Pattern A is "multiply by 2."
Answers
Answer:
The statement that best describes the numerical patterns is;
The rule for mapping Pattern A to Pattern B is "multiply by 2"
Step-by-step explanation:
The given two numerical patterns are;
Pattern A: 4, 8, 12, 16, 20
Pattern B: 8, 16, 24, 32, 40
Therefore;
The ratio of the corresponding terms of Pattern B and A are;
8/4 = 16/8 = 24/12 = 32/16 = 40/20 = 2
We multiply a value in pattern A by 2 to obtain a corresponding value in Pattern B
Therefore the rule for mapping Pattern A to Pattern B is "multiply by 2".

Use the formula [tex]f(x)=asin(bx+c)+d[/tex] where [tex]|a|[/tex] is the amplitude, [tex]-\frac{c}{b}[/tex] is the phase shift, [tex]d[/tex] is the vertical shift, and the period is [tex]\frac{2\pi}{|b|}[/tex].

So, his unit rate = 227.5/5= 45.5 miles per day
Mia drives 332,5 miles in 7 days
So, her unit rate = 332.5/7= 47.5 miles per day
Difference =47.5 - 45.5 = 2 miles per day
So,
Mia drives 2 miles per day more than Joseph.

You need to know how far you are away from the lighthouse.
You use a range finder to find the distance from the sailboat to the lighthouse light is 245 yards.
For angle B, chose an angle measure between 25° and 45°: __________
Based on the above information, find the distance from the sailboat to the island where the lighthouse is located.
Answers
Answer:
The distance from the sailboat to the island where the lighthouse is located is approximately 212.2 yards
Step-by-step explanation:
The distance between the sailboat and the lighthouse is found using trigonometric ratios as follows;
The given parameters are;
The distance from the sailboat to the lighthouse's light = 245 yards
The angle of elevation of angle B = An angle chosen between 25° and 45°
For simplicity, we chose, B = 30°
A right triangle formed with the height of the light house and the horizontal distance of the sailboat from the lighthouse as legs and angle B is the angle adjacent to the horizontal distance of sailboat from the light house
The hypotenuse length = The distance from the sailboat to the lighthouse's light = 245 yards
By trigonometric ratio, in the we have;
[tex]cos\angle B = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]
The adjacent leg length = The horizontal distance of sailboat from the light house
[tex]\therefore cos (30^{\circ}) = \dfrac{The \ horizontal \ distance \ between \ the \ sailboat \ and \ the \ lighthouse }{245 \ yards}[/tex]
The horizontal distance between the sailboat and the light house = 245 × cos(30°) ≈ 212.176223927
Therefore;
The horizontal distance between the sailboat and the lighthouse ≈ 212.2 yards
Therefore, the distance from the sailboat to the island where the lighthouse is located ≈ 212.2 yards.

Answers
Answer:
(0, -5/2), (-2, 0)
Step-by-step explanation:
To find the y-intercept, set x = to 0 and find y: -4y = 10. Thus, y = -5/2. The y-intercept is (0, -5/2).
To find the x-intercept, set y = to 0 and fid x: -5x = 10. Therefore the x-intercept is -2: (-2, 0)
