8. Evaluate the polynomial function
f(x) = -2x4 + 6x3 - 3x + 11 when x = 4
(
-

Answers

Answer 1

Answer:

f(4) = -129

Step-by-step explanation:

Substitute the value of x which is 4

f(x) = -2x4 + 6x3 - 3x + 11

f(4) = -2(4)4 + 6(4)3 - 3(4) + 11

f(4) = -2(256) + 6(64) - 12 + 11

f(4) = -512 + 384 - 1

f(4) = -128 - 1

f(4) = -129

Option C is the correct answer.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

In the case of the function y = 1/(x + 1), the numerator is a constant function, which means that the function has a horizontal asymptote at y = 0.

The denominator, x + 1, is a linear function, which means that the function has a vertical asymptote at x = -1.

Therefore, the graph of the function will have a shape that is similar to a hyperbola.

Thus,

Step-by-step explanation:

First, let's round the cost of each CD to the nearest whole number.

6.98 ≈ 7.00

The closest multiple of 7 to 75 is 77.

Then, it would make sense that Sean can buy 11 CDs. However, he has a little bit under 77 dollars, so he can only buy 10 CDs.

(If we were to do the actual calculations, 75/6.98 is 10.744.. and so on, so we can confirm he can buy no more than 10 CDs)

Blake is working his way through school. He works two part-time jobs for a total of 22 hours a week. Job A pays $5.70 per hour, and Job B pays $7.30 per hour. How many hours did he work at each job the week that he made $141.40.

Answers

Answer:

Job A= 12hrs and Job B= 10hrs

Step-by-step explanation:

first u need to make 2 equations, with 2 variables and the pay per hour for both jobs and let the first equal to the total pay at the end of the week

5.7x + 7.3y = 141.4

then the 2nd equation, let it equal to the total hours worked:

x + y = 22

you then make one of the variables the subject of the formula:

x= 22 - y

and substitute that formula into the first equation you would've made:

5.7(22-y) + 7.3y = 141.4 in this instance you then solve for y:

where y= 10hrs

given that y=10 you can then substitute it into either of the 2 equations:

x+y=22

x= 22-y

x= 22 - 10

x= 12hrs

therefore stating that Blake worked 12 hrs at job A and 10 hrs at job B

Let k be a constant. Compute d/dx [In(kx)] in two ways. Using the Chain Rule, first decompose y = ln(kx) into an outside and inside function.

Answers

The differentiation using the chain rule gives:

[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x) = \frac{1}{(kx)}*k = \frac{1}{x}[/tex]

How to differentiate a logarithmic function?

Remember that:

[tex]ln(x) = \int\limits {\frac{1}{x} } \, dx[/tex]

Now, we want to derivate ln(kx) where k is a constant, the problem tells us to use the chain rule, so we define two functions:

g(x) = ln(x)f(x) = kx

Then we have:

g(f(x))

Remember that the chain rule says that:

[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x)[/tex]

In this case:

g'(x) = 1/xf'(x) = k

Then:

[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x) = \frac{1}{(kx)}*k = \frac{1}{x}[/tex]

The vector of F1 has a angle of 30 and radius of 30 n so the component are

[tex]x = 30( \cos(30) ) = {15 \sqrt{3} }[/tex]

[tex]y = 30 \sin(30) = 15[/tex]

F2 is a 90 degree so

[tex]x = 20 \cos(90) = 0[/tex]

[tex]y = 20\sin(90) = 20[/tex]

F3 is a 240 degree so we have

[tex]x = 35( \cos(240) ) = - 17.5[/tex]

[tex]y = 35 \sin(240) = - 17.5 \sqrt{3} [/tex]

F4 is 310 angle so we have

[tex]x = 40 \cos(310) = - 21.01[/tex]

[tex]y = 40 \sin(310) = 34.04[/tex]

In how many ways can 3 oaks, 4 pines, and 2 maples be arranged along a property line if one does not distinguish among trees of the same kind?

Answers

Total number of ways to arrange the given trees is equals to 24ways.

What is combination?

" Combination is defined as total number of ways arrangement made without considering the order."

Formula used

Fundamental principle of counting

First group has 'm' objects

second group has 'n' objects

Total number of ways objects can be arranged  =m × n

According to the question,

Number of oak trees = 3

Number of pines tree = 4

Number of maples trees = 2

Substitute the given values in the formula we get,

Total number of ways to arrange the given trees = 3 × 4 × 2

                                                                                  = 24ways
