A rain gutter is made from aluminum sheets that
28 cm wide. The first step in forming a rain gutter is to lift the edges of the aluminum sheet to form right angles, as show in in the illustration below. The cross-section
area formed by the raised edges affects the water flow. This cross-section area, A, can be represented by the function A = x(28-2x) where x
represents the height of the raised edges.
1. To the nearest centimetre, determine the height of the raised edge, x cm, which will maximize the
transverse area.
Answer:
7 cmStep-by-step explanation:
For any quadratic function f(x)=ax²+bx+c given in form f(x)=a(x-h)²+k, where:
h=-b/2a and k=f(h) the point (h, k) is vertex of the function graph.
It means that k is maximum (if a<0) or minimum (if a>0) value of function and x=h is the x which will maximize function.
A(x) = x(28-2x) = 28x - 2x² = - 2x² + 28x ⇒ a = -2 , b = 28
h = -28/[2•(-2)] = 7

Any number to the power of zero is always?
Answer:
In short, the multiplicative identity is the number 1, because for any other number x, 1*x = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity,
Answer: Any number to the power of zero would be 1

Answer:
n = 12
Step-by-step explanation:
-8 = 16 - 2n
2n -8 = 16 -2n + 2n (both side add 2n)
2n -8 + 8= 16 +8 (both side add 8)
2n = 24
n = 12
If m/n = 3, what does 2n/m equal?
(Hard) A composite number n is called a Carmichael number bn−1 ≡ 1 (mod n) for every number b such ... Base case: When n = 2 the formula a + c ≡ b + d (mod m) was already given. ... The sequence goes 1, 3, 7, 15, 31,... guess that it is equal to 2n+1 − 1. ... Prove (now using induction on n) that fm|fmn for all n ≥ 1.

Assuming the angle below is drawn to scale, which of the following could be the measure of 2XYZ? A. 120° B. 90 C. 180° O D. 30°
Answer:
Option (A)
Step-by-step explanation:
Given angle in the picture is neither a right angle (equal to 90°) nor obtuse angle (greater than 90°).
It's an acute angle which measures less than 90°.
Therefore, possible measure of the given acute ∠XYZ = 30°
Option (A) will be the answer.

Find the value of x in each case:
Answer:
2x = 36°
8x = 144°
Step-by-step explanation:
8x + 2x = 180°
10x = 180°
x = 180/10
x = 18
then:
2x = 2*18 = 36°
8x = 18*8 = 144°
The value of x from the given diagram is 18. then each angle will be 2x = 36° and 8x = 144°
What is linear equation?Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c
Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.
Also, the triangle ACD, the sum of the interior angle of the triangle is 180 degrees;
8x + 2x = 180°
10x = 180°
x = 180/10
x = 18
Then:
2x = 2*18 = 36°
8x = 18*8 = 144°
Hence the value of x from the given diagram is 18.

26 divided by 5 1/2 I dont know!!
Answer:
4.727
Step-by-step explanation:
An easy way to think of something being divided by a fraction is by turning the fraction into a decimal. In this case, it's 5 1/2, which is the same as 5.5. So, you can just calculate 26 / 5.5, by hand, or on a calculator, and the answer is 4.727.
