please answer the question

Answer:

Step-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

Answer:

7 1/3

Step-by-step explanation:

the 7 stays but 9/27 can be simplified into 1/3 because you divide both 9 and 27 by 9

Answer:

-29x+31y

Step-by-step explanation:

= -12x-17x+15y+16y

=-29x+31y

[tex]36 + 3c = 90 \\ 3c = 90 - 36 \\ 3c = 54 \\ c = 18[/tex]

[tex]5d + 10 = 90 \\ 5d = 90 - 10 \\ 5d = 80 \\ d = 16[/tex]

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.

Hey there!☺

[tex]Answer:\boxed{4\frac{8}{11}}[/tex]

[tex]Explanation:[/tex]

[tex]26/5\frac{1}{2}[/tex]

Divide both fractions.

[tex]26/5\frac{1}{2}=\frac{52}{11}[/tex]

52/11 needs to be simplified so let's simplify it.

[tex]\frac{52}{11}=4\frac{8}{11}[/tex]

[tex]4\frac{8}{11}[/tex] is our final answer.

(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.

x = 4.5

Step-by-step explanation:

l = 2x

p = 4l

note: 4l in this case because it is a square

plug in l into equation p

36 = 4(2x)

36 = 8x

divide by 8

x = 4.5

4600-3900=700

Answer:

700

Step-by-step explanation:

4623 round to the nearest hundred : 4600

3892 round to the nearest hundred: 3900

4600-3900= 700

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:

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°

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.

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°
