Determine whether the given measures can be the lengths of the sides of a triangle write yes or no
2,2,6
NO.,the given measures can not be the lengths of the sides of a triangle
Step-by-step explanation
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
so, Find the range for the measure of the third side of a triangle given the measures of two sides.
here given measures are 2,2,6
2+2 = 4 which is less than the third side 6
= 4 < 6
This not at all a triangle.
Hence, the given measures can not be the lengths of the sides of a triangle
The point (4,5) is translated two units down. What is the y-coordinate of the image?
Answer:
(4,3), y-coordinate is 3
Step-by-step explanation:
If we're translating down, that means we are subtracting however many units we go down by the y-coordinate.
So 5-2=3, and the new y-coordinate is 3
Answer is (4,3)
Step-by-step explanation:
So you need to this...
(x), (y-2)
Now you need to leave the x because It won't do nothing but the y yes because it said bring 2 units down so its (y-2) because its going negative. Now subtract the number you have given.
Now replace y with 5 and subtract 2.
Now you will be given the answer (4,3)
Hope this helps you :)

Owen and Jesse go to a restaurant for breakfast. a 7%sales tax is applied to their $21.60 bill.
if Owen and Jesse add a 15% tip after the tip is applied what is the total cost Including tip
The total cost is about $26.58
The total cost including the sales tax and the tip is approximately $26.58.
The total cost including the sales tax and the tip is calculated as follows:
First, calculate the sales tax by multiplying the bill amount by the sales tax rate:
Sales tax = $21.60 × 7% = $21.60 × 0.07 = $1.512.
Add the sales tax to the original bill to get the total after sales tax:
Total after sales tax = $21.60 + $1.512 = $23.112.
Next, calculate the tip by multiplying the total after sales tax by the tip rate:
Tip = $23.112 × 15% = $23.112 × 0.15 = $3.4668.
Finally, add the tip to the total after sales tax to get the final total cost:
Total cost including tip = $23.112 + $3.4668 = $26.58 (rounded to the nearest cent).

IF IT RIGHT YOU CAN GET 5,000 POINTS AND MARK which of the following pairs of numbers provide the best estimate of Which of the following pairs of numbers provide the best estimate of Which of the following pairs of numbers provide the best estimate of
A.√36 and √64
B.√64 and √81
c.√36 and √49
D.√49 and √64
Answer:
The best is Option D, because the number 7.28 is between 7 and 8 which is a good estimate.
Step-by-step explanation:
Since the square root of 53 is: 7.28...
sqrt(36) = 6
sqrt(64) = 8
sqrt(81) = 9
sqrt(49) = 7
Option D would be the best estimate
Answer: The best is Option D, because the number 7.28 is between 7 and 8 which is a good estimate.
Answer:
D
Step-by-step explanation:
A.√36 and √64 = 6 +8
B.√64 and √81 = 8+9
c.√36 and √49 6+7
D.√49 and √64 7+8
The estimate of 53? is below 8 and above 7 so it is D

What are the solutions of each equation? Use a graph of the related function. a. x2 + 4 = 4 b. x2 + 16 = 0 c. x2 − 49 = 0
The solutions to the equations are: a) x = 0, b) No real solutions, c) x = 7, -7.
Explanation:In order to find the solutions to each equation, we can use a graph of the related function. Let's go through each equation:
a. x² + 4 = 4
Subtracting 4 from both sides of the equation, we get x² = 0. This means x = 0 is the only solution.
b. x² + 16 = 0
Subtracting 16 from both sides gives us x² = -16. Since the square of a real number cannot be negative, there are no real solutions to this equation.
c. x² - 49 = 0
Adding 49 to both sides yields x² = 49. Taking the square root of both sides gives x = ±7. So the solutions to this equation are x = 7 and x = -7.

If y varies inversely with the square of r, what is the constant of proportionality when y - 10 and 1 = 5?
Question:
If y varies inversely with the square of r, what is the constant of proportionality when y =10 and r = 5?
Answer:
The constant of proportionality is 250
Solution:
Given that,
y varies inversely with the square of r
Which means,
[tex]y \propto \frac{1}{r^2}\\\\y = k \times \frac{1}{r^2}[/tex]
Where, "k" is constant of proportionality
Subtitute y = 10 and r = 5
[tex]10 = k \times \frac{1}{5^2}\\\\10 = k \times \frac{1}{25}\\\\k = 10 \times 25\\\\k = 250[/tex]
Thus the constant of proportionality is 250

A parachutist's speed during a free fall reaches 70 meters per second. What is this speed in feet per second? At this speed, how many feet will the parachutist fall during 20 seconds of free fall? In your computations, assume that 1meter is equal to 3.3 feet
Speed is 231 ft/s.
Distance is 4620 ft.
Solution:
First we have to convert the unit of speed from m/s to ft/ s.
Then for 20 seconds, we have to calculate the feet covered by the parachute.
[tex]1 meter $=3.3$ feet\\\\$\frac{70 \frac{m}{s} \times 3.3 f t}{1 m}=231 \frac{f t}{s}$[/tex]
In 20 seconds, the parachute covers the distance of,

Find the value of each variable using sine and cosine.
Answer:
Step-by-step explanation:
Sin 50° = [tex]\frac{opposite}{hypotenuese} = \frac{8}{n}[/tex]
[tex]n=\frac{8}{sin 50}[/tex] = 10.44
Cos 50° = [tex]\frac{adjacent}{hypotenuese} = \frac{m}{n}[/tex]
m = n cos 50 = 6.71
The value of each variable using sine and cosine are,
⇒ n = 10.44
⇒ m = 6.71
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle is shown in image.
Now, By using trigonometry identity we get;
⇒ sin 50° = Opposite / Hypotenuse
⇒ sin 50° = 8 / n
⇒ n = 8 / sin 50°
⇒ n = 10.44
And,
⇒ cos 50° = Adjacent / Hypotenuse
⇒ cos 50° = m / n
⇒ m = 10.44 cos 50°
⇒ m = 6.71
Thus, The value of each variable using sine and cosine are,
⇒ n = 10.44
⇒ m = 6.71
Therefore, The value of each variable using sine and cosine are,
⇒ n = 10.44
⇒ m = 6.71
