10-11d>-5d-4 show step by step

1 answer:

4 0

The first step for solving this is to move the variable to the left side and then change its sign.
10 - 11d + 5d > - 4
Now move the constant to the right side and change its sign.
-11d + 5d > -4 - 10
Collect the terms with a d variable.
-6d > -4 - 10
Calculate the difference on the right side.
-6d > -14
Lastly,, divide both sides of the inequality by -6 and flip the inequality sign to find your final answer.
d < $\frac{7}{3}$
Let me know if you have any further questions.

Step-by-step explanation:

$(3r + 4) + (8r - 2) = 90$

$3r + 4 + 8r - 2= 90$

$11r = 88$

$r = \frac{88}{11} \\$

$r = 8$

If a polynomial function f(x) has roots 1+square root of 2 and-3, what must be a factor of f(x)?

nevsk [136]

To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to $x$ , and then we are going to factor backwards.

We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to $x$ and factor backwards:
$x=-3$
$x+3=0$
$(x+3)$ is a factor of our polynomial.

We also know that another root of our polynomial is $1+ \sqrt{2}$ , so lets set $1+ \sqrt{2}$ equal to $x$ and factor backwards:
$x=1+ \sqrt{2}$
$x-1= \sqrt{2}$
$x-1- \sqrt{2}=0$
$(x-(1+ \sqrt{2})=0$
( $(x-(1+ \sqrt{2} ))$ is a factor of our polynomial.

We can conclude that there is no correct answer in your given choices.

The graphs of the function f (given in blue) and g (given in red) are plotted above. Suppose that u(x)=f(x)g(x) and v(x)=f(x)/g(

Rus_ich [418]

U(x) = f(x).(gx)
v(x) = f(x) / g(x)

Use chain rule to find u(x) and v(x).

u '(x) = f '(x) g(x) + f(x) g'(x)

v ' (x) = [f '(x) g(x) - f(x) g(x)] / [g(x)]^2

The functions given are piecewise.

You need to use the pieces that include the point x = 1.

You can calculate f '(x) and g '(x) at x =1, as the slopes of the lines that define each function.

And the slopes can be calculated graphycally as run / rise of each graph, around the given point.

f '(x) = slope of f (x); at x = 1, f '(1) = run / rise = 1/1 = 1

g '(x) = slope of g(x); at x = 1, g '(1) = run / rise = 1.5/ 1 = 1.5

You also need f (1) = 1 and g(1) = 2

Then:

u '(1) = f '(1) g(1) + f(1) g'(1) = 1*2 + 1*1.5 = 2 + 1.5 = 3.5

v ' (x) = [f '(1) g(1) - f(1) g(1)] / [g(1)]^2 = [1*2 - 1*1.5] / (2)^2 = [2-1.5]/4 =

= 0.5/4 = 0.125

Answers:
u '(1) = 3.5
v '(1) = 0.125
