The simplified value is 2.4 x - 4.4,

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form.

Given:

0.3(4x – 8) – 0.5(–2.4x + 4)

=1.2 x - 2.4 + 1.2x- 2

=2.4 x - 4.4

Hence, the simplified expression is 2.4 x - 4.4.

Answer:

We can not see all the graphs, so i will just do a graph of the system of inequalities, and you can select the option that matches it.

We have the system:

y ≥ 2x + 1

(to represent this, we need to have a solid line y = 2x + 1, and shade all the region above this)

y ≤ 2x - 2

(to represent this, we need to have a solid line y = 2x - 2, and shade all the region below this)

The graph of this system is shown below:

Answer:

3 seconds

Step-by-step explanation:

Given the height modelled by the function

h(t) = -16t² + 16t + 96

The hit the water at h(t) = 0

0 = -16t² + 16t + 96

Divide through b y -16

0 = t² - t - 6

t² - t - 6 = 0

t² - 3t+2t - 6 = 0

t(t-3)+2(t-3) = 0

t+ 2 = 0 and t - 3 = 0

t = -2 secs and t = 3secs

Since t can't be negative, hence;

t = 3 secs

hence it will take 3 seconds until Devon hit the water

Given that,

The equation of line is y=7/5x+ 6 and that passes through the point (2,-6).

To find,

The equation of line that is perpendicular to the given line.

Solution,

The given line is :

y=7/5x+ 6

The slope of this line = 7/5

For two perpendicular lines, the product of slopes of two lines is :

[tex]m_1m_2=-1\\\\m_2=\dfrac{-1}{7/5}\\\\=\dfrac{-5}{7}[/tex]

Equation will be :

y=-5x/7+ b

Now finding the value of b. As it passes through (2,-6). The equation of line will be :

[tex]-6=\dfrac{-5}{7}(2)+b\\\\ -6=\dfrac{-10}{7}+b\\\\b=-6+\dfrac{10}{7}\\\\b=\dfrac{-32}{7}[/tex]

So, the required equation of line is :

y=-5x/7+ (-32/7)

[tex]y=\dfrac{-5x}{7}-\dfrac{-32}{7}[/tex]

Answer:

[tex](a - 2)(2a + 2) \\ = {2a }^{2} + 2a - 4a - 4 \\ = {2a}^{2} - 2a - 4 \\ ({2a}^{2} - 4a) + (2a - 4) \\ 2a(a - 2) + 2(a - 2) \\( a - 2)(2a + 2) \\ a = 2 \\ a = - 1[/tex]

Answer:

[tex]g(a).f(a) = (a - 2)(2a + 2) \\ = 2 {a}^{2} + 2a - 4a - 4 \\ = \boxed{2 {a}^{2} - 2a - 4}[/tex]

Answer:

Angle = Ф = [tex]cos^{-1}[/tex](0) = 0

Hence, it is proved that angle between position vector r and acceleration vector a = 0 and is it never changes.

Step-by-step explanation:

Given vector r(t) = [tex]e^{t}cost i + e^{t}sint j[/tex]

As we know that,

velocity vector = v = [tex]\frac{dr}{dt}[/tex]

Implies that

velocity vector = [tex](e^{t} cost - e^{t} sint)i + (e^{t} sint - e^{t}cost )j[/tex]

As acceleration is velocity over time so:

acceleration vector = a = [tex]\frac{dv}{dt}[/tex]

Implies that

vector a =

[tex](e^{t}cost - e^{t}sint - e^{t}sint - e^{t}cost )i + ( e^{t}sint + e^{t}cost + e^{t}cost - e^{t}sint )j[/tex]

vector a = [tex](-2e^{t}sint) i + ( 2e^{t}cost)j[/tex]

Now scalar product of position vector r and acceleration vector a:

r. a = [tex]<e^{t}cost, e^{t}sint> . <-2e^{t}sint, 2e^{t}cost>\\[/tex]

r.a = [tex]-2e^{2t}sintcost + 2e^{2t}sintcost[/tex]

r.a = 0

Now, for angle between position vector r and acceleration vector a is given by:

cosФ = [tex]\frac{r.a}{|r|.|a|}[/tex] = [tex]\frac{0}{|r|.|a|} = 0[/tex]

Ф = [tex]cos^{-1}[/tex](0) = 0

Hence, it is proved that angle between position vector r and acceleration vector a = 0 and is it never changes.

Answer:

3/2

Step-by-step explanation:

the slope of the equation is -2/3 so the other slope must be opposite reciprocal

Answer:

3/2

Step-by-step explanation:

When you rearrange the equation into y=mx+b, you get y=-2/3x-15

The slope of the given line is -2/3 and you have to take the opposite reciprocal so flip the fraction and change the sign.

This gives the slope 3/2

14*2=28

Given:

I have 13 gallons of water and I pour 10 out.

I have about 10.6 in the container I poured it in.

To find:

The the remaining water.

Solution:

I have 13 gallons of water and I pour 10 out. So, the remaining water after this step is

[tex]13-10=3[/tex]

Then, I have about 10.6 in the container I poured it in. So, the remaining water after this step is

[tex]3+10.6=13.6[/tex]

Therefore, the final remaining amount of water is 13.6 gallons.
