lord [1]

He lost 8, so he is at -8, he then gains 15 so add 15 to -8"-8 + 15 = 7

He gains 7 so now add 7 to the total: 7+ 7 = 14

He then loses 4, so now subtract 4 from the total: 14 - 4 = 10

Given the function: f(x) = 2x3 - 3/2x, find f(-4).

Sergeu [11.5K]

Answer:

D) -122

Step-by-step explanation:

Given:

$f(x) = 2x^3-\frac{3}2x$

We need to find f(-4).

Now by substituting the value of x =-4 in above equation we get;

$f(-4)= 2\times(-4)^3-\frac{3}{2}\times(-4)\\$

By using PEDMAS we will solve for exponential function first we get;

Now we know that $(-4)^3=-64$

So we get;

$f(-4)= 2\times(-64)-\frac{3}{2}\times(-4)\\$

Now using PEDMAS we will solve division.

$f(-4)= 2\times(-64)-1.5\times(-4)$

Now using PEDMAS we solve multiplication.

$f(-4)= -128+6$

Finally by subtraction we get;

$f(-4)= -122$

What is the distance between R(5,2) and S(4,-7)?<br><br> Round to the nearest tenth.

Naddik [55]

You can calculate the distance between two point using this fomula:

√(x_2-x_1)^2+(y_2-y_1)^2

If you insert you values you get:

√(4-5)^2+(-7-2)^2 = 9.06 = 9.1
