Given that -3 is a root of the function h(x)=x^3+2x^2-5x-6, use synthetic division and factoring to indent idt the other roots.

Answer:

∠x = 78

Step-by-step explanation:

∠y + ∠1 = 180

=> 125 + ∠1 = 180

=> ∠1 = 180 - 125

=> ∠1 = 55

∠z + ∠2 = 360

=> 313 + ∠2 = 360

=> ∠2 = 360-313

=> ∠2 = 47

∠1 + ∠2 + ∠x = 180

=> 55 + 47 + ∠x = 180

=> ∠x = 180 - 55 - 47

=> ∠x = 78

Answer:

[tex]x=78[/tex]

Step-by-step explanation:

Skills needed: Exterior Angle Theorem, Triangle Geometry:

1) We need to solve for [tex]x[/tex] and there are 2 methods to do it. I will go over the fastest way (since it's better).

2) In order to use this theorem, we need to solve for the angle near [tex]z[/tex]. This angle would be [tex]360-z[/tex], which is [tex]360-313[/tex] (since [tex]z=313[/tex]).

[tex]360-313[/tex] = [tex]47[/tex]

3) Then, we can use the fact that [tex]y=x+47[/tex] (47 is the measure of the angle we just solved for.)

[tex]y=125[/tex], so [tex]125=x+47[/tex]

Subtract 47 from both sides, and get [tex]x=78[/tex]

Hope you understood and have a nice day! :D

Graphs are used to show the relationship between variables, where the variables are represented by a pair of axes.

Given that:

[tex]C(t) = \frac{-10t^2 + 50t}{t^2 + 4t + 3 }[/tex]

(a): The domain of the function

Because the medication concentration C(t) is a function of time (t), the domain is the possible values t can take.

t, cannot take negative values (i.e. it is not possible to have a negative time).

The least possible value of t is 0

So, the domain of the function based on the context is:

[tex]t \ge 0[/tex]

(b) The greatest concentration of the medication

From the graph (see attachment), the maximum y-value is 5.

Hence, the greatest concentration of the medication is 5 mg/L

A function assigns the values. The greatest concentration of the medication that a patient will have in their body is when the time is t=1.

A function assigns the value of each element of one set to the other specific element of another set.

A.) Given the function of the concentration of medication in the body as to[tex]C(t)=\ \frac{\left(-10t^{2}+50t\right)}{t^{2}+4t+3}[/tex] where t is the time. Since the time can not be negative, therefore, the domain of the function is t≥0.

Answer:

k=-5

Step-by-step explanation:

For the points to be collinear any two pair must have the same slope

We find the slope of the 2nd and 3rd points

=1-2/-1--3

=-1/2

Now finding the slope of the 1st and any other point say point 3

1-3/-1-k=-½

-2/-1-k=-½

-4=-1(-1-k)

-4=1+k

k=-4-1

k=-5

PROOF

if the first point is (-5,3)

slope of point 1 and 2

=2-3/-3--5

=-1/2

Answer:

Step-by-step explanation:

(-5)² = (-5) * (-5) = 25

Here Take square for (-5)

- 5²  = - 5 * 5   = - 25

Here take square for 5

Here we need to remember that:

density = mass/volume

Only by using this equation, we will find that the mass of gold is 19,400 kg

In this case, we know that the gold is in the shape of a cube with side length of one meter.

Remember that for a cube of side length L, the volume is:

V = L^3

Then in this case, the volume of the cube of gold will be:

V = (1m)^3  = 1m^3

And we know that the density of the gold is:

density = 19.4 g/cc

cc = cm^3

density = 19.4 g/cm^3

Notice that we have different units of volume, so we would want to write the volume in cm^3

We know that:

1m^3 = (1×10^6)cm^3

Then the volume of the cube of gold is just:

V = (1×10^6)cm^3 = 1,000,000 cm^3

Now let's return to the density equation:

density = mass/volume

Solving for the mass, we get:

density×volume = mass

Now we can replace the two things in the left side:

(19.4 g/cm^3)×(1,000,000 cm^3) = mass = 19,400,000 g

Now remember that:

1000k = 1kg

Then we can rewrite:

mass = 19,400,000 g = (19,400,000/1000)kg = 19,400 kg

So the cube of gold has a mass of  19,400 kg, there is no way that two persons could carry this much gold into a cave.

Answer:

Second option,domain:  negative infinity, 4 and range, negative infinity, 3

The domain are all the x's that you can input into a function. It looks like the function goes to all x's from negative infinity until it hits positive 4. that's why it is -infinity, 4 for the domain.

The range is all the y's that are outputted. As you can see, the function goes to all y's from negative infinity to 3.

Step-by-step explanation:

Answer:

x = 17

Step-by-step explanation:

We can find the missing angle inside the triangle by doing 180 - 94 = 86.

Every triangle has 3 angles that add up to equal 180 so we can set these three angles to equal 180.

60 + 86 + 2x = 180

146 + 2x = 180

Subtract 146 from both sides

2x = 34

Divide by 2 to isolate x

x = 17

3 - 5

5 - 3

4 - 4

6 - 2

2 - 6

That's 5 ways that it can be done. There are a total of 36 ways to throw 2 dice.

The probability of getting an 8 is 5/36

Perimeter of a triangle is the sum of measures of its all three sides, let the other be y,

we know,

[tex] \hookrightarrow \: y + 3x + 2 + 4x - 9 = 16x - 6[/tex]

[tex] \hookrightarrow \: y + 7x - 7 = 16x - 6[/tex]

[tex] \hookrightarrow \: y = 16x - 6 - 7x + 7[/tex]

[tex] \hookrightarrow \: y = 6x + 1[/tex]

hence, measure of the third side is 6x + 1
