g Find two positive numbers whose sum is 380 and whose product is a maximum. You MUST use optimization methods to solve this.
Answer:
The first number is 190 and the second number is also 190
Step-by-step explanation:
let the first number = x
let the second number = y
The sum of the numbers is given by;
x + y = 380
y = 380 - x
The objective function is given by;
F = xy
F = x(380 -x)
F = 380x - x²
Take the derivative of the function;
F' = 380 - 2x
Find the critical points;
380 - 2x = 0
2x = 380
x = 380 / 2
x = 190
Determine the second number, y;
y = 380 - x
y = 380 - 190
y = 190

Find a radical expressions for the perimeter of the shaded triangle Simplify the expression.
Answer:20+4√17
Step-by-step explanation:
2 of 3 sides are 16 and 4 units . The angle between them is 90 degrees.
So we can find the length of the third side using Pitagor theorem.
c= SQRT( 16²+4²)= sqrt (256+16)= sqrt (272)
So the perimeter of the shaded triangle is equal to
P= 4+16+sqrt(272)=20+4√17
The radical expressions for the perimeter of the shaded triangle is 20 + 4√17
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a rectangle shown in the picture with dimensions.
Using Pythagoras theorem;
The inclined length = √(4²+16²) = √272 = 4√17
The perimeter of the shaded region = 16 + 4 + 4√17
Perimeter = 20 + 4√17
Thus, the radical expressions for the perimeter of the shaded triangle is 20 + 4√17

Answer:
circumference = 150.72cm
area = 1808.64cm²
Step-by-step explanation:
the formula for circumference = 2πr
the formula for area = πr²
24cm is the radius (r)
so therefore
circumference = 2(3.14)(24)
= 150.72cm
area = (3.14)(24)²
= 1808.64cm

If the Internet consisted of four computers, there would be six possible connections. If it consisted of five computers, there would be ten possible connections. How many connections are possible with twenty computers
Answer:
80 possible connections
Step-by-step explanation:
Let the constant k = change in possible connection/number of computers
change in possible connections = 10 - 6 = 4
change in number of computers = 5-4 = 1
k = 10-6/5-4
k = 4/1
k = 4
Since k = possible connections/number of computers:
4 = possible connections/20
possible connections = 4 * 20
possible connections = 80
Hence the possible number of connections with 20 computers are 80 connections

find the angle of y dasdwadasdaw
Answer:
C
Step-by-step explanation:
Since angles x and y lie on a single straight line,
∠x +∠y= 180° (adj. ∠s on a str. line)
Given that ∠x= 42°,
42° +∠y= 180°
∠y= 180° -42° (-42° on both sides)
∠y= 138° (simplify)
Thus, option C is correct.

To rent a certain meeting room, a college charges a reservation fee of $39 and an additional fee of $5.70 per hour. The film club
wants to spend less than $67.50 on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
Use t for the number of hours the meeting room is rented, and solve your inequality for t.
t<5
39 + 5.7t < 67.5
-39
5.7t < 28.5
divide by 5.7
t < 5
the equation Y=1 1/2X represents the number of cups of dried fruit, Y. needed to make X pounds of granola. Determine whether each point would be on the graph of this proportional relationship
(1 1/2,1) (4,6) (18,12) (0,0) (2 1/2. 3 3/4 )
Answer:
[tex]2.\ \ (4,6)[/tex]
[tex]4.\ \ (0,0)[/tex]
[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]
Step-by-step explanation:
Given
[tex]y = 1\frac{1}{2}x[/tex]
Required
Determine if the given points is on the graph
First,, we rewrite [tex]y = 1\frac{1}{2}x[/tex] as
[tex]y = \frac{3}{2}x[/tex]
[tex]1.\ \ (1\frac{1}{2},1)[/tex]
This can be interpreted as:
[tex]x = 1\frac{1}{2}[/tex]
[tex]y = 1[/tex]
Substitute [tex]x = 1\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * 1\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * \frac{3}{2}[/tex]
[tex]y = \frac{9}{4}[/tex]
This isn't equal to the given value of y.
Hence: [tex](1\frac{1}{2},1)[/tex] is not a point on the graph
[tex]2.\ \ (4,6)[/tex]
Here,
[tex]x = 4[/tex]
[tex]y = 6[/tex]
Substitute [tex]x = 4[/tex]
[tex]y = \frac{3}{2} * 4[/tex]
[tex]y = \frac{3 * 4}{2}[/tex]
[tex]y = \frac{12}{2}[/tex]
[tex]y = 6[/tex]
This point is on the graph
[tex]3.\ \ (18,12)[/tex]
Here,
[tex]x = 18[/tex]
[tex]y = 12[/tex]
Substitute [tex]x = 18[/tex]
[tex]y = \frac{3}{2} * 18[/tex]
[tex]y = \frac{3 * 18}{2}[/tex]
[tex]y = \frac{54}{2}[/tex]
[tex]y = 27[/tex]
This isn't equal to the given value of y.
Hence: [tex](18,12)[/tex] is not a point on the graph
[tex]4.\ \ (0,0)[/tex]
Here, we have
[tex]x = 0[/tex]
[tex]y = 0[/tex]
Substitute [tex]x = 0[/tex]
[tex]y = \frac{3}{2} * 0[/tex]
[tex]y = 0[/tex]
Hence:
This point is on the graph
[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]
Here
[tex]x =2\frac{1}{2}[/tex]
[tex]y = 3\frac{3}{4}[/tex]
Substitute [tex]x =2\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * 2\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * \frac{5}{2}[/tex]
[tex]y = \frac{15}{4}[/tex]
[tex]y = 3\frac{3}{4}[/tex]
Hence:
This point is on the graph

3(x-2)+7=16 simplified
9514 1404 393
Answer:
3x +1 = 16
Step-by-step explanation:
"Simplified" usually means parentheses are eliminated and like terms are combined.
3(x -2) +7 = 16 . . . . . given
