Find the length and width of a rectangle with maximum area that has a perimeter of 9P units.

Answers

Answer:

l = 9p/4 , l = 9p/4

Step-by-step explanation:

Given:

Perimeter = 9p

Find:

Length and width

Computation:

Assume;

Length = l

Perimeter = 2(l+b)

9p/2 = l+w

w = 9p/2 - l

Area = lb

Area = l(9p/2 - l)

Using differentiation

l = 9p/4

w = 9p/2 - l

w = 9p/2 - 9p/4

w = 9p/4

g(x) = –2x + 5
Find: (gof)(x)

Answers

Answer:

[tex](g\circ f)(x)=-6x^2 +8x +7[/tex]

Step-by-step explanation:

The Composite Function

Given f(x) and g(x) real functions, the composite function, named (g\circ f)(x) is defined as:

[tex](g\circ f)(x)=g(f(x))[/tex]

For practical purposes, it's found by substituting f into g.

Given the functions:

[tex]f(x) = 3x^2 - 4x - 1[/tex]

[tex]g(x) = -2x + 5[/tex]

We need to find

[tex](g\circ f)(x)=g(f(x))[/tex]

Replace f into g:

[tex](g\circ f)(x)=-2(3x^2 - 4x - 1) + 5[/tex]

Operating:

[tex](g\circ f)(x)=-6x^2 +8x +2 + 5[/tex]

Reducing:

[tex](g\circ f)(x)=-6x^2 +8x +7[/tex]

Thus,

[tex]\boxed{(g\circ f)(x)=-6x^2 +8x +7}[/tex]

lines A and B are parallel lines find the measures of angle 1​

Answers

Answer:

33

Step-by-step explanation:

alternate angles are equal

see attached

The measure of ∠1 is 33° .

What is alternate interior angles?

When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.

According to the question

As given , lines A and B are parallel lines

therefore ,

∠1 = 33°  

∠3 = 57°

they are between parallel line and opposite of transversal line

So, they are alternate interior angles and are equal .

Hence, The measure of ∠1 is 33°  .

Divide the number 484 into two parts in a ratio of 7 : 4. How much bigger is the first number than the second number?

Answers

Answer:

I don't known

Step-by-step explanation:

Answer:

132

Step-by-step explanation:

First, obtain the total of the ratio:

7+4 = 11

Then, make equations:

[tex]\frac{7}{11} =\frac{x}{484}[/tex]      and     [tex]\frac{4}{11} =\frac{x}{484}[/tex]

Next, solve:

11x = 7*484   →    11x = 3388    →    x = 308

11x = 4*484   →    11x = 1936     →    x = 176

Finally, find the difference:

308 - 176 = 132

(**If it is asking how many times bigger... 308/176 = 1.75 or  [tex]\frac{7}{4}[/tex] )

Answers

Yes, it does. The ground is bumpy and it creates friction acting against the car's motion.

Step-by-step explanation:

This is a fun one! Think about a ball rolling on a smooth surface, now on a bumpy sandpapery one. Which one do you think is faster? The smooth surface! This is because of this friction of the sandpaper which slows down the ball. On the other hand, the smooth one has very little friction. The same applies to cars.

Xavier is solving a problem on the whiteboard as shown.
Part A. Is Xavier's solution correct? If not, identify where he made an error.
Part B. Solve 7950 divided by 25.

Answers

Solution 1 :3/4 ÷ 1/2 = B

Solution 2 :

Quantity of trail mix with Monty = 3/4 pounds

Quantity of pounds he need to divide it into = 1/8

Number of trail mix bags Monty will have =

= 3/4 ÷ 1/8

= 3/4 × 8/1 ( division of fraction is multiplication with reciprocal )

= 24/4

We know that both 24 and 4 is divisible by 4 . Hence ,

= 24 ÷ 4 / 4 ÷ 4

= 6/1

= 6 bags

Therefore , Monty will have 6 bags of trail mix .

Solution 3 :

Quantity of food an elephant eats in 16 hours = 525 pounds

Quantity of food the elephant will eat in 1 hour = 525 ÷ 16

Quantity of food the elephant will eat in 1 hour = 32.8125 pounds = 33 pounds

Therefore , an elephant eats 33 pounds of food in 1 hour .

Solution 4 :

Number of tickets that can be purchased with $14 = 1 ticket

Number of tickets that can be purchased with $500 =

= 500 ÷ 14

= 35 tickets

Therefore , 35 tickets can be purchased with $500 .

Solution 5 :

Factors of 45 = 1 , 5 , 3, 9 , 15 and 45 .

Factors of 27 = 1 , 3 , 9 and 27 .

Their Greatest common factor = 9 .

Then , the sum of 45 and 27 can be written as :

9 ( 5 + 3 )

Therefore , Mr . Morris wrote = 9 ( 5 + 3 ) .

Solution 6 :

Total number of event flyers in a club = 4896

Total number of playerz in a club = 24

Then number of flyers each member of the club will get =

= 4896 ÷ 24

= 204

Therefore , each player will get 204 flyers .

Solution 7 :

Part A is not given .

Part B :

= 7950 ÷ 25

= 318

Therefore , 7950 ÷ 25 = 318 .
