Answer:
The absolute maximum value of f on [-2, 4] occurs at x = 4.
Step-by-step explanation:
We know that the absolute maximum value of f(x) on this interval will occur at either a critical point or an endpoint. The critical points are any point where f'(x) is either equal to zero or not defined. Since f is a polynomial, f'(x) = 3x^2 - 6x is always defined, but is equal to zero at x = 0 and x = 2. We can check the value of f(x) at each critical point and endpoint:
f(-2) = -8
f(0) = 12
f(2) = 8
f(4) = 28
Therefore, f has an absolute maximum value of 28 on the closed interval [-2, 4], which occurs when x = 4.

hikes 30% more miles than on Monday. What is the
NEW AMOUNT of miles she hikes on Tuesday?
Answer:
10.4 miles

For 0° ≤ x < 360°, what are the solutions to sin(StartFraction x Over 2 EndFraction) + cos(x) – 1 = 0 ?
{30°, 150°}
{60°, 300°}
{120°, 240°}
{210°, 330°}
{60°, 300°}
Using the half angle identity:
[tex]\sin\left(\frac{x}{2}\right)+\cos\left(x\right)-1=0\\\sin\left(\frac{x}{2}\right)+1-2\sin^{2}\left(\frac{x}{2}\right)-1=0\\\sin\left(\frac{x}{2}\right)-2\sin^{2}\left(\frac{x}{2}\right)=0\\\sin\left(\frac{x}{2}\right)\left(1-2\sin\left(\frac{x}{2}\right)\right)=0\\[/tex]
Using zero product rule:
[tex]\sin\left(\frac{x}{2}\right)=0,\frac{1}{2}\\x=\frac{x}{2}=0,30,150,180\\x=0,60,300,360[/tex]
Since, 0° ≤ x < 360°, so, x=60,300

2 Why is adding 6, 10, and 5 to a number the same as
adding 21 to that number?
Answer:because 6, 10, and 5 equal 21
Adding 6, 10, and 5 to a number the same as adding 21 to that number, because sum of 6, 10, and 5 is 21.
Given that, adding 6, 10, and 5 to a number the same as adding 21 to that number.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the unknown number be x.
Add 6, 10, and 5 to x, we get x+6+10+5 = x+21
Add 21 to x = x+21
So equation is x+21 = x+21
Therefore, adding 6, 10, and 5 to a number the same as adding 21 to that number, because sum of 6, 10, and 5 is 21.

x=2y-6;y=3x-7
substitution to solve systems of equations
As you said, we can solve this system for y by using substitution.
[tex]x = 2y - 6\\y = 3x - 7\\\\y = 3(2y - 6) - 7\\\\y = 6y - 18 - 7\\\\y = 6y - 25\\\\-5y = -25\\\\y = 5[/tex]
Now, using what we got for y, we plug it into one of the original equations to solve for x.
[tex]x = 2(5) - 6\\\\x = 10 - 6\\\\x = 4[/tex]
Now we have the solution of this system.

For the given equations x=2y-6 and y=3x-7 the value of x is 4 and the value of y is 5.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two equations are x=2y-6 and y=3x-7. The value of x and y will be calculated as,
x=2y-6
y=3x-7
Solve the above equations by substitution method,
x=2(3x-7)-6
x = 6x -14 - 6
6x - x = 20
5x = 20
x = 4
The value of y will be calculated as,
y=3x-7
y = ( 3 x 4) - 7
y = 12 - 7
y = 5

Answer:

sub
Step-by-step explanation:
The missing reasons for the given two column proof are respectively;
Reason 2; Definition of Supplementary angles
Reason 3; Substitution Property of Equality
Reason 4;Subtraction Property of Equality
How to complete the two column proof?From the two column proof, we are given that;
m∠2 = m∠3
Now, for m∠1 + m∠2 = 180°, we see that m∠1 and m∠2 are on a straight line and we know that angles on a straight line sum up to 180°. Thus, the reason is because they are supplementary angles.
Similarly, m∠3 and m∠4 are on a straight line and as such;
m∠3 + m∠4 = 180°
m∠1 + m∠2 = m∠3 + m∠4. This is true because of substitution property of equality.
Lastly, since m∠2 = m∠3, then it means that they will cancel out in the statement 3 and as such we now have;
m∠1 = m∠4. The reason is subtraction property of equality
