Answer:

f(x)*g(x)  =   [tex]-2x^{3} - 12x^{2} - 27x - 44[/tex]

Step-by-step explanation:

I am assuming that * means multiplication

(f*g)(x) = f(x)*g(x)

So, f(x)*g(x)  =  (-x-4)([tex]2x^{2} + 4x + 11[/tex]) = [tex]-2x^{3} - 4x^{2} - 11x - 8x^{2} - 16x - 44[/tex]

                                                       =  [tex]-2x^{3} - 12x^{2} - 27x - 44[/tex]

Answer:  D) 10

============================================================

Explanation:

I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.

So,

DE = 2*(MN)

3x-2 = 2*(x+4)

3x-2 = 2x+8

3x-2x = 8+2

x = 10

Answer:

a.1633rad/min

b.1715feet/min

Step-by-step explanation:

We are given that

Diameter of wheel, d=2.1 feet

Radius of wheel, r=[tex]\frac{d}{2}=\frac{2.1}{2}[/tex]feet

Rate=260 rev/min

a. We have to find the angular speed of the wheel in rad/min

1 rev=[tex]2\pi[/tex]radian

Where [tex]\pi=3.14[/tex]

Using the value

Angular speed=[tex]260\times 2\times 3.14/min[/tex]

Angular speed,[tex]\omega=1633rad/min[/tex]

(b)

Speed=[tex]r\omega[/tex]

Using the formula

Speed of  the cyclist=[tex]\frac{2.1}{2}\times 1633[/tex]feet/min

Speed of  the cyclist=1714.65[tex]\approx 1715[/tex]feet/min

Answer:

Answer:

750%

Step-by-step explanation:

We know that 100% of 5 is 5,

200% of 5 is 10,

300% of 5 is 15,

400% of 5 is 20,

500% of 5 is 25,

600% of 5 is 30,

700% of 5 is 35,

800% of 5 is 40.

So 37 1/2 percent of 5 must be between 700 and 800 percent of 5. We also know that 2.5 is 50% of 5, and 35 + 2.5 = 37.5. So 37 1/2 is 750% of 5

Los números racionales son aquellos números que pueden ser expresados como una relación entre dos enteros. Por ejemplo, las fracciones 1/3 y –1111/8 ambas son números racionales. Todos los enteros están incluídos en los números racionales, ya que cualquier entero z puede ser escrito como la relación z /1.

D

Answer:

D

Step-by-step explanation:

Let's look at the statement.

7y = 14x  and  y = 2x does have infinitely many solutions. Why? Because the first equation can be rearranged to look like the second one. If you divide 7y and 14x by 7, you end up with y = 2x. Look familiar? This means the set of equations has infinitely many solutions.

168.75

Step-by-step explanation:

Answer: A

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

Slope intercept form is y=mx+b where x is our slope and b is our y value. Thefore, 3 is our y value not 4.

Given:

An exponential function goes through points (0,6) and (5, 6144).

To find:

The exponential function.

Solution:

The general form of an exponential function is

[tex]y=ab^x[/tex]          ...(i)

It goes through points (0,6) and (5, 6144). It means the equation must be satisfied by these two points.

Putting x=0 and y=6, we get

[tex]6=ab^0[/tex]

[tex]6=a[/tex]

Putting a=6, x=5 and y=6144, we get

[tex]6144=6b^5[/tex]

[tex]\dfrac{6144}{6}=b^5[/tex]

[tex]1024=b^5[/tex]

Taking 5th root on both sides, we get

[tex]\sqrt[5]{1024}=b[/tex]

[tex]4=b[/tex]

Putting a=6 and b=4, we get

[tex]y=6(4)^x[/tex]

Therefore, the required exponential function is [tex]y=6(4)^x[/tex].

(hope this helps can i plz have brainlist :D hehe)

Step-by-step explanation:

111km

the ratio is 1:15 so you do 7.4×15

The total distance traveled was 638.3m.

To calculate the perimeter of a circle we perform the following operations:

We must keep in mind that the radius of a circle is equal to half the diameter, so the radius of this circle is 100m divided by 2.

So the radius of this circle is 50m.

Subsequently, to find the perimeter of the circle we apply the following formula:

According to this operation, the distance traveled in one lap would be 314.15m. So in two turns it would be:

314.15m × 2 = 638.3m
