Answer:
Stationary points are (0, 5) and (4/3, 103/27)
Step-by-step explanation:
At stationary point (turning point), dy/dx :
[tex]y = {x}^{3} - 2 {x}^{2} + 5 \\ \frac{dy}{dx} = 3 {x}^{2} - 4x \\ \\ \frac{dy}{dx} = x(3x - 4)[/tex]
but dy/dx = 0:
[tex]x(3x - 4) = 0 \\ either \: x \: is \: 0 \: and \: (3x - 4) = 0 \\ x = 0 \\ and \\ 3x - 4 = 0 \\ x = \frac{4}{3} [/tex]
let y = x³ - 2x² + 5:
[tex]when \: x \: is \: 0 \\ y = 5 \\ when \: x \: is \: \frac{4}{3} \\ \\ y = {( \frac{4}{3}) }^{3} - 2 {( \frac{4}{3} )}^{2} + 5 \\ \\ y = \frac{103}{27} [/tex]

I hope I helped you^_^
Answer:
[tex] = 3n + m + 2p[/tex] (first option)
Step-by-step explanation:
[tex]4n - m + 3p + 2m - n - p[/tex]
[tex]4n - n = 4n - 1n = (4 - 1)n = 3n[/tex]
[tex]3n - m + 3p + 2m - p[/tex]
[tex] - m + 2 = - 1m + 2m = ( - 1 + 2)m = 1m = m[/tex]
[tex]3n + m + 3p - p[/tex]
[tex]3p - p = 3p - 1p = (3 - 1)p = 2p[/tex]

1.3/4 part of number of students are girls and 120 students are boy. how many student are there altogether *
Answer:
159 students.
Since all you need to do is multiply 120×1.3/4=39, then you add 120, as we are told that there are 120 boys. Basically, there are 39 girls and 120 boys, since by multiplying 20×1.3/4 equals 39, so 39 girls, and 120 boys. Now add them all together, 120+39=159.

− 4 − [2+4( − 6) − 4 −(2²-5×21)]
Answer:
1
Step-by-step explanation:
First, solve four your last bracket, 2 squared is 4 and minus 5 is -1 times 21 is -21. Yet because the outer symbol is a negative, all signs change-making 21 positive. Solve 4*-6, and you get -24. This leaves you with [2-24-4+21] that gives you -5. Yet, because the outer sympol is a negative, 5 becomes positive. This leaves you with 1.
Answer:
71
Step-by-step explanation:
− 4 − [2 + 4(− 6) − 4 − (2²- 5×21)]
− 4 − [2 + 4(− 6) − 4 − (4 - 5×21)]
− 4 − [2 + (-24) − 4 − (4 - 105)]
− 4 − [-22 − 4 − (-101)]
− 4 − [-22 − 4 + 101]

Write an absolute value inequality for the graph below. Use x for your variable.
Answer:
|x| ≥ 7
Step-by-step explanation:
Taking the absolute value means that any value of x will always be positive, meaning that the absolute value of -7 or less would be 7 or greater, which satisfies the inequality above and line graph.
Absolute value is 7 or greater.
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
p ≠ q means that p is not equal to qp < q means that p is less than qp > q means that p is greater than qp ≤ q means that p is less than or equal to qp ≥ q means that p is greater than or equal to qAs, absolute value means that any value of x will always be positive.
So, the absolute value according to -7 or less would be 7 or greater,
Hence, absolute value is 7 or greater.

write a polynomial in standard form with the zeros –4 0 1 and 4
Step-by-step explanation:
Hi there!
Zero of the polynomial is the value of "X" that gives final answer as zero.
So, as the polynomial in the second gives zero every time when we keep the zero which are given in the question. It is the answer.
Check:
• x⁴ - x³ - 16x² + 16x
(-4)Keep the value -4 as the value of X in polynomial.
= (-4)⁴-(-4)³ -16*(-4)²+16*(-4)
= 256+64-256-64
= 0
0Keep the value 0 as the value of X in polynomial.
= (0)⁴-(0)³ -16*(0)²+16*(0)
= 0-0-0+0
= 0
1Keep the value 1 as the value of X in polynomial.
= (1)⁴-(1)³ -16*(1)²+16*(1)
= 1-1-16+16
= 0
4Keep the value 4 as the value of X in polynomial.
= (4)⁴-(4)³ -16*(4)²+16*(4)
= 256 - 64-256+64
= 0
Therefore, the correct answer is option B.

The letters a and b represent nonzero constants solve
ax-b=12.5 for x
Answer:
x=(12.5+b)/a
Step-by-step explanation:
ax-b=12.5
ax=12.5+b
x=(12.5+b)/a
The solution for the equation ax - b = 12.5 for x is:
x = (12.5 + b) / a
We have,
To solve the equation ax - b = 12.5 for x, follow these steps:
- Add b to both sides of the equation:
ax - b + b = 12.5 + b
This simplifies to:
ax = 12.5 + b
- Divide both sides of the equation by "a":
(ax) / a = (12.5 + b) / a
Simplify:
x = (12.5 + b) / a
Thus,
The solution for the equation ax - b = 12.5 for x is:
x = (12.5 + b) / a
