Answer:
D (last one), [tex]x^2+y^2=45[/tex]
Step-by-step explanation:
We need to find the distance between (0,0) and (-3,6). Using the distance formula we get:
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]d=\sqrt{\left(-3-0\right)^2+\left(6-0\right)^2}[/tex]
[tex]d=3\sqrt{5}[/tex]
Since equation of circle is: [tex]x^2+y^2=r^2[/tex] we have to square the distance we just found, which gives us 45.
Answer:
x^2 + y^2 = 45
Step-by-step explanation:
(x − a ) ^2 + ( y − b ) ^2 =r^2
= (-3-0)^(2)+(6-0)^(2)
=45

In 2011, a professional climber scaled the outside of the Burj Khalifa, making it all the way to 828 meters (the highest point on which a person can stand) in 6 hours.
Answer:
276 meters in the first 2 hours
Step-by-step explanation:
Given that,
Professional climbers climb 828 meters in 6 hours.
Let us assume we need to find how far did they climb in the first 2 hours.
6 hours = 828 m
⇒ 1 hour = 138 m
So, in 2 hours,
2 hours = 138 × 2 m
= 276 m
So, the climber climb 276 meters in the first 2 hours

Find C. Leave your answer in simplified radical form.
9514 1404 393
Answer:
7√2
Step-by-step explanation:
The triangle is a "special triangle", an isosceles right triangle. The side lengths of this triangle have the ratios 1 : 1 : √2. Multiplying these ratio values by 7, the length of the leg, you find ...
c = 7×√2
c = 7√2
_____
If you like, you can go through the Pythagorean theorem and/or trigonometry to find the same thing.
7/c = sin(45°)
c = 7/sin(45°) = 7/(1/√2) = 7√2
Or ...
c² = 7² + 7² = 98 . . . . using the Pythagorean theorem*
c = √98 = 7√2
__
* This requires you recognize the triangle is isosceles, so the other leg is also 7. Of course, you know that as soon as you see a 45° acute angle in a right triangle.
Please help, Thank you.
Answer:
It's all about the ratios of corresponding sides.

x=13.33
Step-by-step explanation:
4/x=(4+3)/(x+=10) this is the ratio
4(x+10)=(3+4)(x)
4x+40=7x
4x-4x+40=7x-4x
3x=40
x=13.33
26 sit ups in 2 minutes . find the unit rate and how many in 5 minutes
Answer:
Unit rate: 13 sit ups per minute
65 sit ups can be done in 5 minutes
Step-by-step explanation:
Find the unit rate by dividing 26 by 2
26/2
= 13
This means 13 sit ups can be done in 1 minute.
To find how many can be done in 5 minutes, multiply 13 by 5.
13(5)
= 65
So, the unit rate is 13 sit ups per minute, and 65 sit ups can be done in 5 minutes.

The total length of two ships is 2341 feet. The difference in their lengths is 13 feet.
a. Find the length of each ship.
b. If a football field has a length of 100 yards, determine the length of the longer ship in terms of football fields.
Answer:
The smaller ship is 1,164 ft
The larger ship is 1,177 ft
The larger ship is 3.923 football fields
Step-by-step explanation:
A. Find the length of each ship
x + x + 13 = 2,341 ft
2x + 13 = 2,341 ft
2x = 2,328 ft
x = 2,328/2
x = 1,164 ft ( This is the length of the smaller ship)
1,164 + 13 = 1,177 ft (length of the larger ship)
B)If a football field has a length of 100 yards, determine the length of the longer ship in terms of football fields.
1,177/3ft= 392.3 yards
392.3 yards /100 yards = 3.923 football fields

Tell whether the equation has one, zero, or infinitely many solutions.9(x − 3) + 15 = 9x − 11.
Answer:
Zero solutions; there are no variables and thus there are no solutions
Step-by-step explanation:
We start out with the equation 9 (x - 3) + 15 = 9x - 11
Which simplifies to 9x - 27 + 15 = 9x - 11
The 9x terms cancel each other out, and we're left with 15 - 27 = -11
And we end up with -12 = -11, which is not true.
This tells us that the equation has zero solutions, because no matter what value we substitute for x, the equation will not be true.
Answer:
No solution
Step-by-step explanation:
9(x-3)+15= 9x-11
9x-27+15=9x-11
-15 on both sides
9x-27=9x-26
add 26 on both sides
9x -1=9x
add 1 on both sides
9x=9x+1
divide 9 on both sides
x=x+1/9
No solution

5x - 2y = -10
3x + 6y = 66
Answer:
y = 5/2x + 5
y = -1/2x + 11
Step-by-step explanation:
5x -2y = -10
-2y = - 5x -10
y = 5/2x + 5
3x + 6y = 66
6y = -3x + 66
y = -1/2x + 11

i have to show work
Answer:
Step-by-step explanation:
amount of discount = $10
percentage discount = $10/$39.99 ≅ 0.25 = 25%
amount of sales tax = $1.95
sales tax rate = $1.95/$29.99 ≅ 0.065 = 6.5%
cost of jeans × 1.60 = $39.99
cost of jeans = $39.99/1.60 ≅ $24.99
discounted selling price = $29.99
markup = $29.99/$24.99 ≅ 1.20 = 20%

When a ball is dropped, the function () = 4(0.6)x models the ball’s height in feet after each bounce, where x is the bounce number. To the nearest hundredth, what is the height after the third bounce?
Answer:
7.2 feet
Step-by-step explanation:
plug in x = 3 since we are looking for the height after the 3rd bounce
4(0.6)(3)
4(1.8)
7.2
The height after the third bounce is 0.86 feet.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 4 x [tex]0.6^x[/tex] models the ball’s height in feet after each bounce.
Where x is the bounce number.
Now,
Substituting x = 3,
f(x) = 4 x [tex]0.6^x[/tex]
f(x) = 4 x [tex]0.6^3[/tex]
f(x) = 4 x 0.6 x 0.6 x 0.6
f(x) = 0.864
f(x) = 0.86
The height after the third bounce is 0.86 feet.

Option 2 (open circle at 6 with arrow going to the right.
Step-by-step explanation:
Open circle means "excluding that number". Since x>6, x cannot be 6 so we have an open circle at 6. x>6 also means x has to be greater than 6, so we have the arrow going to the right since 7 is greater than 6, 8 is greater than 6, and so on so forth.
Amanda bought tickets for a concert for $218. Jamie bought tickets to the same concert but paid 14% less than Amanda. What were the price of Jamie's tickets?
Answer:
Jamie's tickets = $187.48
Step-by-step explanation:
The amount for which Amanda bought tickets = $218
Jamie bought tickets to the same concert but paid 14% less than Amanda.
Jamie's tickets = [tex]218-14\%\ of\ 218[/tex]
We can solve it as follows :
[tex]218-14\%\ of\ 218=218-\dfrac{14}{100}\times 218\\\\=218-30.52\\\\=\$187.48[/tex]
So, the price of Jamie's tickets is $187.48.
Marcus purchased 4 1/2 pounds of rice on Monday and 2 1/3 pounds of rice on Tuesday, What was the total weight, in pounds, of rice purchased by Marcus in the two-day period?
A. 6 1/6
B. 6 2/5
C. 6 1/3
D. 6 5/6
E. 7 5/6
Answer:
he would have bought 6 5/6 pounds of rice.
Step-by-step explanation:
4 1/2 + 2 1/3 = ?
First, you want to get common dominaters. And the closest number is 6
4 3/6 + 2 2/6 = 6 5/6
This can not be simplifyed so that would be your answer.
The total weight, in pounds, of rice purchased by Marcus in the two-day period is [tex]6\frac{5}{6}[/tex] pounds.
Addition of fraction:It is given that,
Amount of rice purchased on Monday = [tex]4\frac{1}{2} pounds[/tex]
Amount of rice purchased on Tuesday[tex]=2\frac{1}{3} pounds[/tex]
the total weight, in pounds, of rice purchased by Marcus in the two-day period is computed as;
[tex]=4\frac{1}{2}+2\frac{1}{3} \\\\=\frac{9}{2} +\frac{7}{3} \\\\=\frac{27+14}{6} \\\\=\frac{41}{6}\\ \\=6\frac{5}{6} pounds[/tex]
Therefore, the total weight of rice is [tex]6\frac{5}{6}[/tex] pounds.
