Answer:

18x^2 - 9

Step-by-step explanation:

y = f(x)= 6x^3 - 9x + 4

dy/dx = d/dx(6x^3) - d/dx(9x) + d/dx (4)

=6.d/dx(x^3) - 9.d/dx (x) + d/dx. (4)

=6.3x^2 - 9.1 + 0 =18x^2 - 9

$Subtract~16~from~both~sides:$

$\frac{f}{4} +16-16$ < $49-16$

$Simplify:$

$\frac{f}{4}$ < $33$

$Now,~multiply~both~sides~by~4:$

$\frac{4f}{4}$ < $33\times4$

$f$ < $132$

The steps Quentin took to evaluate the expression 3m - 3+3 when m = 8

kicyunya [14]

Answer:

Subtracted 3 from (24+3)

Step-by-step explanation:

3m - 3 + 3

24 - 3 + 3

Since the adding and subtracting go left to right, you can do them in that order.

21+3 = 24.

Now which one gives us 24?

(24+3) - 3

2 m³ of soil containing 35% sand was mixed into 6 m³ of soil containing 15% sand. What is the sand content of the mixture?

Alex17521 [72]

.2 m^3 is 10 percent
.2 m^3 is 10 percent
.2 m^3 is 10 percent
.1 m^3 is 5 percent
therefore
.7m^3 is 35%

.6m^3 is 10%
.3 m^3 is 5%
so .9m^3 is 15 %

all in .9m^3 +.7m^3 = 1.6 m^3 will be sand

Write an equation for the nth term of the arithmetic sequence. Then find a50.

julia-pushkina [17]

Step-by-step explanation:

Since the sequence above is an arithmetic sequence

For an nth term in an arithmetic sequence

A(n) = a + ( n - 1)d

where a is the first term

n is the number of terms

d is the common difference

From the question

a = 1/3

d = 1/2 - 1/3 = 1/6 or 2/3 - 1/2 = 1/6

Substitute the values into the above formula

That's

So the nth term of the sequence is

For a50 since we are finding the 50th term

n = 50

So we have

We have the final answer as

Hope this helps you
