Answer:
It’s (3<em>p</em>, 3<em>p</em> + 4).
Step-by-step explanation:
Substitute the <em>x</em> in the equation (<em>x</em> + 4) with its value, 3<em>p</em>, for the <em>y</em> value—(3<em>p</em>, 3<em>p</em> + 4).
Answer: the statement “measure of <4 is 105 degrees” is incorrect.
Explanation: This is because since both angles 1 and 3 are vertical, this means they are both 95. This gives us 190 (95x2). Now we subtract this from 360 which gives us 170. Since angles 2 and 4 are vertical, we divide by 2, which gives us 85, not 105.
Hope this helps! :)
Answer:
discriminant: 241
2 real roots
Step-by-step explanation:
The discriminant is the part of the quadratic equation that is under the sqare root
x=(-b±√(b²-4ac))/2a
discriminant: b²-4ac
We also know that a quadratic equation is in the form ax²+bx+c = 0, so we can plug in the values we know from our equation to find the discriminant.
a=4
b=-17
c=3
(-17)^2-4(4)(3)
We also know that if the discriminant
is positive we have 2 real roots
is 0 we have 1 real root aka a repeated real solution
is negative we have no real roots
Answer:
Look at the image,
Step-by-step explanation:
This is an explanation of the same exercise but when the paraboloid is z = 9 − x2 − y2. In that case you just have to replace 9 by 4 and follow the same steps :).
