Write the standard form of the equation of the circle with center (7,1) that also contains the point (−1,−5).
Enter the equation in simplest terms.
pls no links. my computer can't open
Answer:
[tex](x-7)^2+(y-1)^2=100[/tex]
Step-by-step explanation:
1) Find the radius
We can do this by using the distance equation with the centre (7,1) and the given point (-1,-5):
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (7,1) and (-1,-5)
[tex]d=\sqrt{(-1-7)^2+(-5-1)^2}\\d=\sqrt{(-8)^2+(-6)^2}\\d=\sqrt{64+36}\\d=\sqrt{100}\\d=10[/tex]
Therefore, the radius of the circle is 10 units.
2) Plug the data into the equation of a circle
Equation of a circle (when not centred at the origin):
[tex](x-h)^2+(y-k)^2=r^2[/tex] where the centre is [tex](h,k)[/tex] and r is the radius
Plug in the centre (7,1) as (h,k)
[tex](x-7)^2+(y-1)^2=r^2[/tex]
Plug in the radius 10
[tex](x-7)^2+(y-1)^2=10^2\\(x-7)^2+(y-1)^2=100[/tex]
I hope this helps!
Compare using benchmark fractions or 1. Then choose Yes or No to tell if the comparison is correct.
1/3 > 1/6 Choose... (Yes or No)
4/3 > 8/6 Choose... (Yes or No)
6/5 > 5/6 Choose... (Yes or No)
3/8 < 1/4 Choose... (Yes or No)
Please answer the question quickly if the answer is known.
Thank you!
The comparison of the above fractions are correctly listed below:
1/3 > 1/6 = yes
4/3 > 8/6= No
6/5 > 5/6 = Yes
3/8 < 1/4 = No
What is a fractionA fraction is defined as the part of a whole value which is represented as a numerator and a denominator form.
1/3 is greater than 1/6 because 1/3 = 0.3 which is greater than 1/6 = 0.2
4/3 is not greater than 8/6 because 4/3 = 1.3 which is equivalent to 8/6 = 1.3.
6/5 is greater than 5/6 because 6/5 = 1.2 which is greater than 5/6 = 0.8
3/8 is not less than 1/4 because 3/8 = 0.4 which is greater than 1/4 = 0.3.

Find the derivative of f(x) = -12x2 + 9x at x = 6.
a) -112.5
b)-135
c)90
d)108
hi
f(x) = -12x²+9x
So
f'(x) = -24x +9
if x = 6 then f'(6) = -24 (6) +9 = -135

[tex] \frac{1}{x + 1} \geqslant \frac{3}{x - 2} [/tex]
Answer:
( -∞, -2.5] ∪ (-1, 2)
Step-by-step explanation:
1/(x + 1) ≥ 3/(x - 2)
x - 2 ≥ 3(x + 1)
x - 2 ≥ 3x + 3
x - 3x ≥ 3 + 2
-2x ≥ 5

A train moving at 40km/h applies brakes so that there is a constant 0.5m/s².find the time taken before the train stops.
Answer:
t = 22.22 s
Step-by-step explanation:
Given that,
The initial speed of the train, u = 40 km/h
Acceleration of the train, a = 0.5 m/s²
Finally, it stops, v = 0
We need to find the time taken by it to stop. using first equation of motion to find it such that,
[tex]v=u+at\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{0-40\times \dfrac{5}{18}}{-0.5}\\\\t=22.22\ s[/tex]
So, it will take 22.22 seconds to stop.

For soccer season, Cameron wants to buy a new soccer ball, a pair of shorts, and a pair of soccer shoes. The ball costs $4.95, the shorts cost $9.10, and the shoes cost $5.50. Cameron has $2.30. How much more money does Cameron need?
Add the three items he wants to buy:
4.95 + 9.10 + 5.50 = 19.55
Subtract how much he has already:
19.55 - 2.30 = 17.25
He needs $17.25 more
