Answer:

q = 0, q = 9

Step-by-step explanation:

Given

18q - 2q² = 0 ← factor out 2q from each term

2q(9 - q) = 0

Equate each factor to zero and solve for q

2q = 0 ⇒ q = 0

9 - q = 0 ⇒ q = 9

Find two positive integers such that the sum of the first number and four times the second number is 1000, and the product of th

vladimir2022 [97]

Answer:

The two numbers are:

x = 500

y = 125

Step-by-step explanation:

We want to find two numbers x and y, such that:

x + 4*y = 1000

f(x, y) = x*y is maximum.

From the first equation, we can isolate one of the variables to get

x = 1000 - 4y

now we can replace it in f(x, y):

x*y = (1000 - 4*y)*y = 1000*y - 4*y^2

So now we want to maximize the function:

f(y) =- 4*y^2 + 1000*y

where y must be an integer.

Notice that this is a quadratic equation with a negative leading coefficient (so the arms of the graph will open downwards), thus, the maximum will be at the vertex.

Remember that for a general quadratic equation:

y = a*x^2 + bx + c

the x-value of the vertex is:

x = -b/(2*a)

so, in the case of:

f(y) =- 4*y^2 + 1000*y

the y-value of the vertex will be:

y = -1000/(2*-4) = 1000/8 = 125

So we found the value of y.

now we can use the equation:

x = 1000 - 4*y

x = 1000 - 4*125 = 1000 - 500 = 500

x = 500

Then the two numbers are:

x =500

y = 125

I NEED HELP ASAP

SVEN [57.7K]

Alright, lets get started.

If the polygon measures 45 degree exterior angle and we are asked to find number of sides, there is a formula for that.

$\frac{360}{n}$ = value of exterior angle

Where n is number of sides of ploygon

$\frac{360}{n} = 45$

Multiplying n into both sides

$\frac{360}{n} * n = 45 n$

$360 = 45 n$

Now divide 45 in both sides

$\frac{360}{45} = \frac{45n}{n} = n = 8$

n = 8

Means number of sides of polygon is 8, hence its Octagon. Answer

Now we have given 45 exterior angle hence interior angle would be

180 - 45 = 135°

So, sum of all interior angles would be = number of sides * interior angle

sum of all interior angles would be = $8 * 135 = 1080$

Hence sum of all interior angles would be 1080°. Answer

Hope it will help :)
