Y = x² + 6x + 3
olganol [36]

Vertex<em> </em>is at \left(-3,-6\right)

<em>y-intercept</em> is 3.

The parabola <em>opens up</em>.

Step-by-step explanation:

The graph of the equation is hereby attached in the answer area.

Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here(x =-3), is shown with the dotted line in the graph attached.

<em>y-intercept </em>is defined as the value of y where the graph crosses the y-axis. In other words, when x=0. Putting

And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of x in the given equation y =x^{2} + 6x + 3. Here, co-efficient of

So, vertex<em> </em>is at \left(-3,-6\right)

<em>y-intercept</em> is 3.

The parabola <em>opens up</em>.

Given the graphs of f(x) = x – 1 and g(x) = –x – 7, what is the solution to the equation f(x) = g(x)?
Ghella [55]

Answer:

(-3, -4)

Step-by-step explanation:

f(x) = x – 1 and g(x) = –x – 7

f(x) = g(x)

  • x-1= -x-7
  • 2x= -6
  • x= -3
  • f,g= -4

Can someone please help me ?
Alex

Answer:

  B.  π(3/2)²h

  (27/4)π cubic inches

Step-by-step explanation:

A. The formula for the volume of a cylinder is ...

  V = πr²h

The radius (r) is half the diameter, so for a diameter of 3 inches, the radius is 3/2 inches. When this is put into the formula, the volume is ...

  V = π(3/2)²h . . . . . . matches choice B

__

B. When h=3, the volume evaluates to ...

  V = π(9/4)(3) = (27/4)π . . . . cubic inches

PLZ HELP ASAP! URGENT! Plz help me solve without using algebra plz, our teacher doesn’t allow us to use it. TYSM!!!
Cloud [144]
Your teacher is right.  There is no reason to use algebra, which is misused in many problems as a shortcut, and slows the actual learning of math skills.

Here, the solution is as follows:
1. Find the volume of water in tank X.
2. Find the TOTAL base area of the three tanks, imagine that you have a larger tank with the same base area as the sum of the three.
3. Find the height of water in the new tank.

1. Find the volume of water in tank X.
Volume = 32*20*39.5=25280 cm^3

2. Find the TOTAL base area of the three tanks, imagine that you have a larger tank with the same base area as the sum of the three.
Total base area = 32*20 + 30*16 + 20*8 = 640+480+160 = 1280 cm^2

3. Find the height of water in the new tank
Height = Volume / base area 
= 25280 / 1280
= 19.75 cm
