Solve for x, which can be done by moving x to the other side.
2(x-5)^2+8
So, x = 5
The y value is the number at the end and we can see that it is positive 8.
y = 8
Write it out as a coordinate pair and you would get (5,8) or answer choice D
Answer:
A= (0,0) and B = (6,3)
We can find the length AB with the following formula:
![d = \sqrt{(x_B -x_A)^2 +(y_B -y_A)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%28x_B%20-x_A%29%5E2%20%2B%28y_B%20-y_A%29%5E2%7D)
And replacing we got:
![d = \sqrt{(6-0)^2 +(3-0)^2} = \sqrt{45}= 3\sqrt{5}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%286-0%29%5E2%20%2B%283-0%29%5E2%7D%20%3D%20%5Csqrt%7B45%7D%3D%203%5Csqrt%7B5%7D)
So then the length AB would be ![3\sqrt{5}](https://tex.z-dn.net/?f=%203%5Csqrt%7B5%7D)
Step-by-step explanation:
For this case we have the following two points:
A= (0,0) and B = (6,3)
We can find the length AB with the following formula:
![d = \sqrt{(x_B -x_A)^2 +(y_B -y_A)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%28x_B%20-x_A%29%5E2%20%2B%28y_B%20-y_A%29%5E2%7D)
And replacing we got:
![d = \sqrt{(6-0)^2 +(3-0)^2} = \sqrt{45}= 3\sqrt{5}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%286-0%29%5E2%20%2B%283-0%29%5E2%7D%20%3D%20%5Csqrt%7B45%7D%3D%203%5Csqrt%7B5%7D)
So then the length AB would be ![3\sqrt{5}](https://tex.z-dn.net/?f=%203%5Csqrt%7B5%7D)
Answer:
Given confidence interval is 0.54+or-0.05
0.54-0.05,0.54+0.05 =
(0.49,0.59)
In repeated sampling,the true proportion of country residents in favor of offering incentives to high-tech industries to build plants in the country will fall in the interval (0.49,0.59)
Answer:
y = -5
Step-by-step explanation:
Isolate y:
-3x + 9y = -57
9y = -57 + 3x
y = (-57/9) + (3/9)x
Substitute for x:
y = (-57/9) + (3/9)(4)
y = (-57/9) + (12/9)
y = (-45/9)
y = -5
It would be c. You always start with what’s between the parentheses. So start with 4+5 which equals 9. Then you’ll do 9+2 which is 11. And there’s your answer
