Which of the number(s) below are potential roots
Gnom [1K]

Answer:

+1 is the potential root of the function.

Step-by-step explanation:

Given;

p(x) = x⁴ + 22x⁴ – 16x - 12

A potential root of the function is zero of the function. That is a potential root will reduce the function to  zero or close to zero.

To determine this, we test each of the root given;

p(6) = (6)⁴ + 22(6)⁴ - 16(6) - 12 = 29700

p(3) = (3)⁴ + 22(3)⁴ - 16(3) - 12 = 1803

p(1) = (1)⁴ + 22(1)⁴ - 16(1) - 12 = -5

p(8) = (8)⁴ + 22(8)⁴ - 16(8) - 12 = 94068

The only number that reduces the function close to zero is +1, then +1 is the potential root of the function.

What is the excluded value? y2-y+5/y+4
WITCHER [35]
The given term is: \frac{ y^{2}-y+5 }{y+4} 

Since here, the numerator i.e. y^{2}-y+5 cannot be factorized. 

SO, the only excluded value is found on the basis of the denominator. The denominator should not be equal to 0, otherwise, the fraction will turn out to be zero.
SO, if y \neq -4, then denominator will not be zero.
Therefore, the excluded value is -4

The front of a dog house is in the shape of a isosceles triangle. If the sides measuring 4 feet and the base of the house is 6 f
kirill [66]

Answer: \sqrt{5} feet

Step-by-step explanation: Since it's an isosceles triangle, we can split it into  two right triangles. Now we have two right triangles with a hypotenuse of 4 and one side length of 3. To solve for the other side length (the height), we can use the Pythagorean theorem. 4^{2}  = 3^{2} + h^{2} where h is the height of the dog house. Solving for h, we get the answer of \sqrt{5} feet
