Answer:x=√−y2+18y−56 or x=−√−y2+18y−56
Step-by-step explanation:
x2+(y−9)2=25
Step 1: Add -y^2 to both sides.
x2+y2−18y+81+−y2=25+−y2
x2−18y+81=−y2+25
Step 2: Add 18y to both sides.
x2−18y+81+18y=−y2+25+18y
x2+81=−y2+18y+25
Step 3: Add -81 to both sides.
x2+81+−81=−y2+18y+25+−81
x2=−y2+18y−56
Step 4: Take square root.
x=√−y2+18y−56 or x=−√−y2+18y−56
Answer:
x=√−y2+18y−56 or x=−√−y2+18y−56
Students drop a 2 kg object from rest out a window that has a
height of 10 m during a lab experiment. The students time the
object to hit the ground and measure 1.2 s. Calculate the
difference between the PE at the top and the KE at the bottom.
a. greater than 75 J
b. less than 25 J
c. between 25 J & 50 J
d. between 50 J & 75 J
Answer:
a. greater than 75 J
Step-by-step explanation:
Potential Energy at the top = mgh
Mass m = 2kg
g = 9.8m/s^2
height h = 10m
Potential Energy at the top = 2 * 10 * 9.8
Potential Energy at the top = 196Joules
The object is not moving at the bottom, hence the KE of the body at the bottom is 0Joules
difference between the PE at the top and the KE at the bottom = 196 - 0 = 196Joules
Hence the difference between the PE at the top and the KE at the bottom is greater than 75Joules

-2x + 4 = 12
Explain what mistake did he make
Answer:
X=-4
Step-by-step explanation:
-2x + 4 = 12
so what you would do is subtract 4 from itself and 12
4 - 4 = 0
12 - 4 = 8
then we have-
-2x = 8
we then divide 2 from 2 and 8
2 divided by 2 = 0
2 divided by 8 = 4
so x = -4

Solve algebraically the simultaneous equations
x^2+y^2=25
y-3x=13
Answer:
In the form of (x,y) there are 2 solutions:
(-3,4)
(-24/5, -7/5)
Step-by-step explanation:
First isolate one of the letters (for me I'm using the y of equation 2 because it's easier to solve)
[tex]y-3x=13\\y=13+3x[/tex]
Now that we have y isolated, substitute y in equation 1 with the equation we got previously (y=13+3x)
[tex]x^2+(13+3x)^2=25[/tex]
Now simplify:
[tex]x^2+(13+3x)^2=25\\x^2+9x^2+78x+169=25\\10x^2+78x+169=25[/tex]
Now turn the equation into ax^2+bx+c=0 form by transferring 25 to the other side of the equation:
[tex]10x^2+78x+169=25\\10x^2+78x+169-25=0\\10x^2+78x+144=0[/tex]
Using the quadratic formula we will have the 2 following values:
[tex]x=-3[/tex]
[tex]x=-\frac{24}{5}[/tex]
Substitute the following values into any equation you want (this time I'll pick equation 2 again since its the easiest to solve)
[tex]y-3x=13\\y-3(-3)=13\\y-(-9)=13\\y+9=13\\y=13-9\\y=4[/tex]
[tex]y-3x=13\\y-3(-\frac{24}{5})=13\\y-(-\frac{72}{5})=13\\y+\frac{72}{5}=13\\y=13-\frac{72}{5}\\y=-\frac{7}{5}[/tex]

Step-by-step explanation:
A Cylinder has a radius of 10 feet and a height of 11.4 feet what is the approximate volume of the cylinder?
Answer:
3579.6 [tex]ft^{3}[/tex]
Step-by-step explanation:
First, write out the equation used to find the volume of a cylinder and place the values in place of the variables. The equation is [tex]\pi[/tex][tex]r^{2}[/tex]*h where r is the radius and h is the height. When we place the values of the variables into the equation we get: [tex]\pi[/tex][tex]10^{2}[/tex]*11.4. Next, square 10 to get 100. This would give you 3.14*100*11.4. When you multiply this together you get 314 times 11.4 which gives you 3579.6 ft cubed.
I believe it's 3581.42 (if the answer needs be rounded to 2 decimal places.
Step-by-step explanation:
area of circle = r×r×π
area of circle × height = volume
10 × 10 × π = 314.16
314.16 × 11.4 = 3581.42

PLS HELP ME!!!!!!!!!!! Satish's register shows a deposit on February 4 in the amount of $150.00, an atm withdrawal on February 5 in the amount of $180, and another deposit on February 7 in the amount of $225.56. What should Satish's balance in his register be? A. $610.82, B.$792.91, C.$910.82, or D.$947.14
Answer:
Balance = $195.56
Step-by-step explanation:
Credit:
Feb 4 deposit = $150.00
Feb 7 deposit = $225.56
Total credit = $375.56
Debit:
Feb 5 ATM withdrawal = $180
Total Debit = $180
Balance = credit - debit
= $375.56 - $180
= $195.56
Balance = $195.56
The answer is not included in the option. It is either the options are not correct or the values in the question are not correct. Please recheck

Total credit = $150 + $225.56 = $375.56
Debit:
Feb 5 withdrawal = $180
Total Debit = $180
Balance = $375.56 - $180 = $195.56
Satish's balance in his register would be $195.56

Calculate the area and perimeter of the polygon.
Answer:
a) P = 24.2 units
b) A = 13.9 square units
Step-by-step explanation:
Perimeter = [tex]\sqrt{10}[/tex]+[tex]\sqrt{10}[/tex] + 4[tex]\sqrt{5}[/tex] + 4[tex]\sqrt{5}[/tex]
P = 2[tex]\sqrt{10}[/tex] + 8[tex]\sqrt{5}[/tex] which is approx 24.2 units
To find area you must find the height which can be done using the Pythagorean Theorem (we can do this for the small triangle on the left):
([tex]\sqrt{5}[/tex]²) + h² = ([tex]\sqrt{10}[/tex]²)
5 + h² = 10
h² = 5
h = [tex]\sqrt{5}[/tex]
A = bh
A = [tex]\sqrt{5}[/tex] (4 + [tex]\sqrt{5}[/tex])
A = 4[tex]\sqrt{5}[/tex] + 5 which is approx 13.9 square units
