<em>This is very much linear</em>. You can tell because this function (line) passes the vertical line test. It has one output for each input and if a vertical line went through it it would only intersect at one spot at a time.

What is the formula of 20 is 4% of what number. How do you get the whole number
lutik1710 [3]

Well we know 4% is just 4/100.

So 20 = 4/100.

Let's find out what 1/100 is and multiply that by 100:

20/4 = 5.

So 1/100 = 5.

5*100 = 500.

Which point is not on the graph represented by y=x^2+2x-4
Illusion [34]
(-6,20) \\&#10;x=-6 \\ y=20 \\ \Downarrow \\&#10;20 \stackrel{?}{=} (-6)^2+2 \times (-6)-4 \\&#10;20 \stackrel{?}{=} 36-12-4 \\&#10;20 \stackrel{?}{=} 20 \\&#10;20 = 20 \\&#10;\hbox{the point is on the graph}

(-4,4) \\&#10;x=-4 \\ y=4 \\ \Downarrow \\&#10;4 \stackrel{?}{=} (-4)^2+2 \times (-4)-4 \\&#10;4 \stackrel{?}{=} 16-8-4 \\&#10;4 \stackrel{?}{=} 4 \\&#10;4 = 4 \\&#10;\hbox{the point is on the graph}

Both points are on the graph.

Surface Area of a Cylinder Formula: SA = 2πrh + 2πr²

  • <em>r</em> is radius
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>r</em> = 11 in

<em>h</em> = 23 in

<u>Step 2: Find Surface Area</u>

  1. Substitute in variables [Surface Area of a Cylinder Formula]:                       SA = 2π(11 in)(23 in) + 2π(11 in)²
  2. Evaluate exponents:                                                                                         SA = 2π(11 in)(23 in) + 2π(121 in²)
  3. Multiply:                                                                                                             SA = 506π in² + 242π in²
  4. Add:                                                                                                                   SA = 748π in²

Write the equation in standard form for the circle with center (0, – 10) and radius 6.
Artemon [7]

Answer:

Equation of circle in standard form with centre (0, – 10) and radius 6. \mathbf{x^2+(y+10)^2=36}

Step-by-step explanation:

We need to write equation of circle in standard form with centre (0, – 10) and radius 6.

The equation of circle is: (x-h)^2+(y-k)^2=r^2

where (h,k) is centre of circle and r is radius

We are given centre (0,-10) so, h=0, k=-10 and radius r = 6

Putting values and finding equation:

(x-h)^2+(y-k)^2=r^2\\(x-0)^2+(y-(-10))^2=(6)^2\\x^2+(y+10)^2=36

So, equation of circle in standard form with centre (0, – 10) and radius 6. \mathbf{x^2+(y+10)^2=36}
