Answer:

The point of intersection with the x axis are (-2,0) and (8,0)

Step-by-step explanation:

given circle equation x²+y² = 25

x² + y² = r²

r is the radius.

✓(25) = 5

given the center is at (3,0) and radius of 5

(3+5,0) and (3-5,0)

(8,0) and (-2,0)

(Please heart the answer if you find it helpful, it's a motivation for me to help more people)

Solve the equation for u.<br> Uw + uq=r
soldi70 [24.7K]

Answer:  u= \frac{r}{w+q}

Step-by-step explanation:

uw + uq = r To solve for u  factor  the left side to eliminate the other variables.

u ( w + q) = r   Now divide both sides by w+q

u = \frac{r}{w+q}

Why is math important “?
Pavlova-9 [17]

Answer:

Without math, how would we know how to count seconds minutes, etc.?

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the zeros 4 and 3−
Neko [114]

Answer:

P(x) = x^3 - 10x^2+ 34x-40

Step-by-step explanation:

Given

p =1 -- Leading coefficient

Zeros: 4\ and\ 3  - i

Required

Determine the polynomial

Represent the zeros with a and b

Such that

a = 4

b = 3 - i

The polynomial is:

P(x) = p * (x - a) * (x - b)

P(x) = 1 * (x - 4) * (x - (3 - i))

However, to solve further: We need to symmetrise over 3-i  and its conjugate

P(x) = 1 * (x - 4) * (x - (3 - i))* (x - (3 + i))

P(x) =  (x - 4) * (x - (3 - i))* (x - (3 + i))\\\\

To define a suitable function, the expression becomes

P(x) =  (x - 4) * ((x - 3)^2+1)

P(x) =  (x - 4) * ((x - 3)(x - 3)+1)

P(x) =  (x - 4) * (x^2 - 6x + 9+1)

P(x) =  (x - 4) * (x^2 - 6x +10)

Open bracket

P(x) = x^3 - 6x^2 +10x - 4x^2 + 24x-40

P(x) = x^3 - 6x^2  - 4x^2+10x + 24x-40

P(x) = x^3 - 10x^2+ 34x-40
