the function l(x) = 3x

3 + 2x

2 − 4x + 5 and the width represented by the function w(x) = x + 2.


Part A: Find the area of the label.


Part B: Which of the following statements are true about the area of the label? Select ALL that apply.

 A(x) = l(x) + w(x)

 The resulting polynomial for A(x) will be a 4th degree polynomial

 l(x) =

A(x)

w(x)


 The resulting polynomial for A(x) will have a leading coefficient of 6

 A(x) = l(x) ∙ w(x)

 The resulting polynomial for A(x) will have a constant term of 10

Answers

Answer 1

Answer:

The answers are

°the resulting polynomial for A(x) will be a 4th degree polynomial

°l(x)= a(x)/w(x)

°A(x)= l(x)·w(x)

|8x+3|=12 what’s the answer

Answers

Answer:

x= 9/8 , -15/8

Step-by-step explanation:

Answer:

x = 1.125 , x = 9/8

Step-by-step explanation:

|8x+3| = 12

=> 8x + 3 = 12

=> 8x = 12-3 = 9

=> 8x = 9

=> x = 9/8

As 9/8 is a fraction let's make it a decimal.

9/8 * 125/125 (To make it into a power of ten so that we can convert)

=> 1125 / 1000

=> 1.125

The safe load for a horizontal beam supported at both ends varies
jointly as the width and the square of its depth and inversely as
the distance between the supports. If a 4 cm by 6 cm beam,
10 m long supports 5 kg when standing on the edge, what is the
safe load if the beam is turned on its side?

Answers

Answer:

The formula would be

wd^2c/l = p

(2*1^2c)/4 = 10

(2*1c)/4 = 10

2c/4 = 10

c = 20

3*2^2*20/6 = p

3*4*20/6 = p

240 pounds

hope it help :)

Step-by-step explanation:

The safe load if the beam is turned on its side will be 240 pounds.

What is a load?

A burden or pressure source that is carried by someone or something. Construction loads are defined as the weights placed on an existing or temporary structure both during and after the construction process.

Given that the safe load for a horizontal beam supported at both ends varies jointly with the width and the square of its depth and inversely with the distance between the supports. If a 4 cm by 6 cm beam, 10 m long supports 5 kg when standing on the edge,

The load will be calculated by using the formula below:-

wd²c/l = p

(2 x( 1 ) ²c)/4 = 10

(2x 1c)/4 = 10

2c/4 = 10

c = 20

3 x ( 2 )²x ( 20/6 ) = p

3 x 4x ( 20/6 ) = p

p = 240 pounds

Therefore, the safe load if the beam is turned on its side will be 240 pounds.

Part A
Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?

Answers

Sine he runs 2 miles on Monday, we already have a +2.

Then, he runs by a constant rate of 1, which is the constant rate of change per day.

Let x represent the number of days he runs and y the total amount of miles he runs. Now, the equation is y = x + 2

However, he needs to run at least 6 miles. At least means greater than or equal to. The values for y can be greater than 6, or equal to 6.

y ≥ 6

y = x + 2

Now substitute x + 2 for y.

x + 2 ≥ 6

Subtract 2.

x ≥ 4

This is the inequality. He has to run for at least 4 days.

A deluxe bakery sells a cookie for $2.38, a brownie for $3.07 and a cake for $14.87. On Wednesday they sold 13 cookies, 4 brownies and 4 cakes. The cost in ingredients for each cookie is $1.7, for each brownie is $1.91 and for each cake is $5.83. How much profit did they make on Wednesday?

Answers

Answer:

$ 49.64

Step-by-step explanation:

Selling price of cookie on Wednesday = 13 × 2.38 = $30.94

Selling price for brownie on Wednesday = 4 × 3.07 = $ 12.28

Selling price for cakes on Wednesday = 4 × 14.87 = $ 59.48

Cost price for cookie = 13 × 1.7 = $ 22.1

Cost price for brownie = 4 × 1.91 = $ 7.64

Cost price for cakes = 4 × 5.83 =$ 23.32

Total profit for Wednesday= Total selling price - total cost price

That is;

(30.94 + 12.28 + 59.48) - (22.1 + 7.64 +23.32) = $ 49.64

Answers

Answer:32ft

Step-by-step explanation: I missed this as well, ED and AB are the same and if you don’t read you skip over the fact ED equals 32ft. Since ED and AB equal eachother it would be 32ft

The value of AB = 32 feet

What is congruency ?

Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same.

Given:

EC= 32 ft = BC

DC= 28 ft =AC

<ECD= <BCA

So, In ΔECD and ΔBCA

EC = BC

DC= AC

<ECD= <BCA

Thus, by SAS ΔECD ≅  ΔBCA

Hence, by CPCT : ED= BA = 32 ft.
