Answer:

120º

Step-by-step explanation:

<1 has almost the same size as the angle above D. But you can see it is more pushed in just a little bit so that means that its a little but less so its 120º angles.

Hope this helps!

please <3 me! It really helps me out also :3

which equation forms a pair of linear equations with 9x + 12y = 48 such that the system has no solution?

MA_775_DIABLO [31]

Answer:

Option D

Step-by-step explanation:

The given equation is 9x + 12y = 48.

When we simplify this equation by dividing through by 3, we obtain:

$3x + 4y = 12$

The slope-intercept form is

$y = - \frac{3}{4} x + 3$

The slope is

$- \frac{3}{4}$

and the y-intercept is 3.

An equation that forms a pair of linear equations with 9x + 12y = 48 such that the system has no solution must have a slope of

$- \frac{3}{4}$

and a y-intercept not equal to 3.

That should obviously be the last option.

D) 6x +8y=32

The slope-intercept form is:

$y = - \frac{3}{4} x + 8$

Express the polynomial as a product of linear factors.

Bas_tet [7]

Answer:

D. 3(x - 1)(x+3)(x + 2).

Step-by-step explanation:

3(x - 1)(x + 3)(x + 2)

= 3(x - 1)(x^2 + 5x + 6)

= 3(x^3 + 5x^2 + 6x - x^2 - 5x - 6)

= 3(x^3 + 4x^2 + x - 6)

= 3x^3 + 12x^2 + 3x - 18.

You are given the height and the circumference of the base of a cylinder. Describe how to find the surface area of the entire cy

Talja [164]

Hello from MrBillDoesMath!

Answer:

2 * (Pi r^2) + (Pi r^2)*h

where r = C/(2 Pi)

Discussion:

Total surface area of cylinder =

area of bottoms + surface area of cylinder =

2 * area of base + (area of base) * h

Generally, C = 2 Pi r, so r = C/(2 Pi) is known as we are given C. . Plugging this in the above equation gives

2 * (Pi r^2) + (Pi r^2)*h

Thank you,

MrB

1. Graph the function f(x)=4cos(x). (Be sure to label your x-axis.)

Mekhanik [1.2K]

ANSWER

To graph the function

$y=4cos(x)$ we need to plot some few points within one period. Since the interval is not given, we shall use $[0,2 \pi]$ '

$\left \begin{array}{cc}x&y=4cos(x)\\0 &4\\\frac{\pi}{2}&0 \\ \pi&-4\\\frac{3\pi}{2} &0\\2\pi&4\end{array}\right$ .

We plot the above points to obtain the graph as shown in the attachment.
