Answer:

The correct answer is:  Option 3.

Step-by-step explanation:

To begin the problem asks to find f· g which can be defined as [f*g](x). Now we are given that:

f(x)=-5x+3\\g(x)=6x-2

So now we need to 'multiply' our two algebraic expressions as follow:

fg(x)=(-5x+3)(6x-2)\\fg(x)=(-5x)(6x) +(-2)(-5x)+(3)(6x)+(3)(-2)\\fg(x)=-30x^2+10x+18x-6\\fg(x)=-30x^2+28x-6 Eqn.(1)

The domain of Eqn. (1) is all real numbers of x.

Which according to the given options , Option 3 is correct.

How many models of 100 do you need to model 3200 explain ​
rusak2 [61]

32 models need to make model of 3200.

Given that a 1 model contain 100.

Two series of numbers, usually empirical data, that are proportional or proportional if their respective elements are in constant proportion, called the scaling factor or the rate constant.

One model has 100 elements.

Now, we have to find how many model contains 3200 elements.

So, 1 model=100 elements

n model =3200 elements

We will write this in proportion as

1/n=100/3200

Applying the cross multiply, we get

3200×1=n×100

Divide both sides with 100, we get

3200/100=100n/100

3200/100=n

32=n

Hence, the  32 models contain 3200 elements when one contain 100 elements.

A sack of potatoes weighs 14 pounds 9 ounces after wendy makes potato salad for a picnic the sack weights 9 pounds 14 ounces wha
dlinn [17]
For this case we have the following conversion:
 1 pound = 16 ounces
 Then we rewrite the sack weights:
 14 pounds 9 ounces = 14 9/16
 9 pounds 14 ounces = 9 14/16 = 9 7/8
 Then, we subtract both values:
 (14 9/16) - (9 7/8) = 4.6875 = 4 + 0.6875
 Rewriting:
 4 + 0.6875 = 4 + 6875/1000
 4 + 1375/200 = 4 + 275/40
 4 + 275/40 = 4 + 55/8
 Answer:
 
the weight of the potatoes wendy use for the potato salad is:
 
4 + 55/8 pounds
