Answer:
Given equation:
(x-9)^2 + (y-4)^2 = 36Equation of circle:
(x - h)^2 + (y - k)^2 = r^2Compare and get the values:
h = 9k = 4r ^2 = 36 ⇒ r = 6d = 2r = 2*6 = 12A TV costs £800 plus Vat at 20%.
What is the total cost of the TV?
Answer:
£960
Step-by-step explanation:
20% of 800 = 160
800 + 160 = 960

Enter the x-coordinate of the solution to this system of equations
−2x−y=6
8x+3y=−28
x= ?
I have trouble with these kinds of problems so a mini explanation would really help me out :)
Answer:
equation 2into minus 3 into equation 1
8x+ 3y= -28
-3x-3y=18
----------------
5x=10
x =2
put value of y in equation 2
8 into 2+3y=-28
16+3y= -28
3y= -28+16
3y= -12
y= -4
If sinA = cosB, what is the relationship between A and B if A is obuse angled and B is acute angled ?
Answer:
According to the law of sines, \dfrac{AB}{\sin(\angle C)}=\dfrac{AC}{\sin(\angle B)}
sin(∠C)
AB

sin(∠B)
AC
start fraction, A, B, divided by, sine, left parenthesis, angle, C, right parenthesis, end fraction, equals, start fraction, A, C, divided by, sine, left parenthesis, angle, B, right parenthesis, end fraction. Now we can plug the values and solve:
\begin{aligned} \dfrac{AB}{\sin(\angle C)}&=\dfrac{AC}{\sin(\angle B)} \\\\ \dfrac{5}{\sin(33^\circ)}&=\dfrac{AC}{\sin(67^\circ)}\\\\ \dfrac{5\sin(67^\circ)}{\sin(33^\circ)}&=AC \\\\ 8.45&\approx AC \end{aligned}

I suppose you just have to simplify this expression.
(2ˣ⁺² - 2ˣ⁺³) / (2ˣ⁺¹ - 2ˣ⁺²)
Divide through every term by the lowest power of 2, which would be x + 1 :
… = (2ˣ⁺²/2ˣ⁺¹ - 2ˣ⁺³/2ˣ⁺¹) / (2ˣ⁺¹/2ˣ⁺¹ - 2ˣ⁺²/2ˣ⁺¹)
Recall that nª / nᵇ = nª⁻ᵇ, so that we have
… = (2⁽ˣ⁺²⁾ ⁻ ⁽ˣ⁺¹⁾ - 2⁽ˣ⁺³⁾ ⁻ ⁽ˣ⁺¹⁾) / (2⁽ˣ⁺¹⁾ ⁻ ⁽ˣ⁺¹⁾ - 2⁽ˣ⁺²⁾ ⁻ ⁽ˣ⁺¹⁾)
… = (2¹ - 2²) / (2⁰ - 2¹)
… = (2 - 4) / (1 - 2)
… = (-2) / (-1)
… = 2
Another way to get the same result: rewrite every term as a multiple of y = 2ˣ :
… = (2²×2ˣ - 2³×2ˣ) / (2×2ˣ - 2²×2ˣ)
… = (4×2ˣ - 8×2ˣ) / (2×2ˣ - 4×2ˣ)
… = (4y - 8y) / (2y - 4y)
… = (-4y) / (-2y)
… = 2

Order these numbers from least to greatest.
2.5, 2.304, 3.21, 2.34
Answer:
2.304, 2.34, 2.5, 3.21
Step-by-step explanation:
1. Look at the digit in the ones place. See how they are all 2s except for one 3? Well, now we know the one with the 3 must be the greatest, since 3>2.
2. Next, look at the digit in the tenths place. We have a 3, 3, and a 5. Since 5 > 3, we know thar 2.5 is the second greatest.
3. Last, look at the hundreths place. We have a 0 and a 4. Since 4 > 0, that means 2.34 is the third greatest.
4. Since this is from least to greatest, put 2.304 first and the others as follows in the answer. Hope this helps.

A pool is filling up at a rate 7 gallons per minute. which equation best represents y, the total amount in the pool after x minutes?
A. x=7y
B. y=7x
C. y=7+x
D. x=7+y
B. y = 7x
7x is the steady rate of 7 gallons per minute. The number of minutes can also be plugged into x to find the volume of the pool after x minutes.
B. y=7x
y represents the amount of water in the pool after x minutes, that means it's going to be the result.
x represents minutes.
you are multiplying it because it's per minutes

If nkf ~ lzf, find nf, please help me with this it’s due tmr!!!!
Answer:
NF = 25
Step-by-step explanation:
Since ∆NKF ~ ∆LZF, the ratio of their corresponding side lengths would also be the same.
This means that:
KF/ZF = NF/LF
KF = x + 3
ZF = 4
NF = 15 + x + 3 = x + 18
LF = x + 3
Plug in the values into the equation
(x + 3)/4 = (x + 18)/(x + 3)
Cross multiply
(x + 3)(x + 3) = (x + 18)(4)
x² + 3x + 3x + 9 = 4x + 72
x² + 6x + 9 = 4x + 72
x² + 6x + 9 - 4x - 72 = 0
x² + 2x - 63 = 0
Factorize to find x
x² + 9x - 7x - 63 = 0
x(x + 9) -7(x + 9) = 0
(x + 9)(x - 7) = 0
x + 9 = 0 or x - 7 = 0
x = -9 or x = 7
We'd use the positive value of x, which is 7.
Therefore, x = 7.
✅NF = 15 + (x + 3)
Plug in the value of x
NF = 15 + (7 + 3) = 15 + 10
NF = 25
At a cricket club dinner 62 members sat down to eat. The costs
for the club were: first course $44640, main course $59520, dessert
42 800, drinks $31600.
Work out the cost of the dinner per head.
Members were charged $2995 a head. Did the club make a profit
Justify your answer.
Answer:
They made a profit of 7,130 dollars.
Step-by-step explanation:
So since they were charged 2995 a head then all youd have to do is multiply that by the number of people.
2,995 x 62 = 185, 690
Then add the total of the food.
44,640 + 59,520 + 42,800 + 31600 = 178,560
Then subtract their income from the money they spent.
185,690 - 178, 560 = 7,130
