Answer:
Answer is below
Step-by-step explanation:
Evaluate for x=6,y=11
![11^2-6\\11^{2} -6\\=115](https://tex.z-dn.net/?f=11%5E2-6%5C%5C11%5E%7B2%7D%20-6%5C%5C%3D115)
So therefore your answer is 115
Answer:
quadratic
Step-by-step explanation:
Answer:
1: D
2: B
3: y=-4x+22
4: y=-8x+26
Step-by-step explanation:
1: Parallel lines have the same slope, and the only one with a slope of 3x is D
2: Perpendicular lines have an opposite slope, so a line with a slope of -1/2 would be 2, so you just flip the number and add or take away a negative sign, depending on the original slope
3: Like I said before, perpendicular lines have an opposite slope, so the slope would be -4. After you've figured that out, you just plug in the numbers given to you (and remember, x is first, y is last)
Plug in: 6=-4(4)+b
You would then solve for b.
6=-16+b
22=b
Then plug that into y=mx+b, with m being the slope (-4) and b being the y intercept (22)
4: The process for finding parallel and perpendicular lines is very similar, except you don't have to change the slope.
Plug in: 10=-8(2)-b
10=-16+b
26=b
Again, plug that into the equation y=mx+b
Hope I could be of help! Sorry if it doesn't make sense, this is my first time on this website.
Any smooth curve connecting two points is called an arc. The length of the arc m∠QPR is 2.8334π m.
<h3>What is the Length of an Arc?</h3>
Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,
![\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}](https://tex.z-dn.net/?f=%5Crm%7B%20Length%5C%20of%5C%20an%5C%20Arc%20%3D%202%5Ctimes%20%5Cpi%20%5Ctimes%28radius%29%5Ctimes%5Cdfrac%7B%5Ctheta%7D%7B360%7D%20%3D%202%5Cpi%20r%20%5Ctimes%20%5Cdfrac%7B%5Ctheta%7D%7B2%5Cpi%7D)
where
θ is the angle, that which arc creates at the centre of the circle in degree.
Given the radius of the circle is 3m, while the angle made by the arc at the centre of the circle is 170°. Therefore,
The length of an arc = 2πr×(θ/360°) = 2π × 3 ×(170/360°) = 2.8334π m
Hence, the length of the arc m∠QPR is 2.8334π m.
