Answer:

x = 4

x = -2/3

Step-by-step explanation:

3x² - 10x - 8

multiply 3 and -8 which = -24

what 2 factors of -24 that when added make -10

those 2 factors would be -12 and +2

Rewrite the polynomial splitting the middle term using the two factors -12  and  2

3x^2 - 12x + 2x - 8

split it up

3x^2 - 12x

2x - 8

x(3x + 2)

2(x - 4)

pulling out like factors

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

OR

3 ( x - 12/3 )( x + 2/3 ) = 0

3( x - 4 )( x + 2/3 ) = 0

divide both sides by 3

x = 4

x = -2/3

y = -2x

Step-by-step explanation:

Because you are given a point and a slope you use what is called the point-slope formula.

y-y₁=m(x-x₁)

[tex]y-4=-2(x--2) \\ y-4=-2x-4\\y=-2x-4+4\\y=-2x[/tex]

The complete factor of the expression [tex]\rm -5x^3 + 10x^2[/tex] is [tex]\rm -5 x^2 (x - 2)[/tex]correct option is A.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression is [tex]\rm -5x^3 + 10x^2[/tex].

To solve the expression properly we have to take common (-5x²). Then we have

[tex]\rm - 5x^3 + 10x^2 \\\\ - 5x^2 (x - 2)[/tex]

The factor is [tex]\rm -5 x^2 (x -2)[/tex].

just substitute the given values

Answer: answer is 66, this is how i got it.

If a=4     B=2     C=7

Equation: 3ac

First, 3(A=4)   3(4)  for the first one you already said a=4 so you have to put the 4 in the A's spot

Second, 3(4)(C=7)   3(4)(7)   for the letter C you know C is equal to 7, so replace the C with 7,

Third, Now you have to multiple 3x4=12    and multiply 3x7= 21

fourth, Add those two together 33, and multiply by B(2)

Answer:

9  3/4  pages = x    

Step-by-step explanation:

[tex]\frac{pages}{minutes} = \frac{pages}{minutes}[/tex]        change 3 1/4 to a decimal

[tex]\frac{3.25}{8} = \frac{x}{24}[/tex]

[tex]3.25(24) = 8x[/tex]

[tex]78 = 8x[/tex]

[tex]\frac{78}{8} = x[/tex]

[tex]9.75 = x[/tex]  

[tex]9\frac{3}{4} =x[/tex]

working with the fraction

3 1/4 /8 = x/ 24

3 1/4 (24) = 8x            

 13/4 (24) = 8x

  316/4 = 8x

  78 = 8x

78/8 = x

Answer:

v = [tex]\sqrt{2}[/tex]/2

u = [tex]\sqrt{6}[/tex]/2

Step-by-step explanation:

[tex]\sqrt{2}[/tex] is across from the 60 degree angle so the side across from 30 degrees is half that

the hypotenuse is the product of the side opposite 30 degrees and [tex]\sqrt{3}[/tex]

so:

[tex]\sqrt{3}[/tex] × [tex]\sqrt{2}[/tex]/2 = [tex]\sqrt{6}[/tex]/2

we get the graph of cosine function.

Here we have given that the low tides occur at a depth of 2.5 m at 12:00 am and 12:30 pm,

separated by the period of T = 12.5 hours. and also high tides occur at a depth of 5.5 m at 6:15 am and 6:45 pm,

separated by a period of T = 12.5 hours.

From the diagram we have use the value of t tor finding the amplitude

So,

What is the formula of amplitude ?

(max+min)/2

Therefore,

The amplitude is,

[tex]\frac{1}{2} (5.5 - 2.5) = 1.5 m.[/tex]

x(0)=2.5 and x(T/2)=5.5

from the diagram  we can say that the function is periodic

[tex]x(t)=-1.5cos(\frac{2\pi t}{12.30} )+4[/tex]

Therefore,

we get the graph of cosine function.
