Hi there!

Let's start with RATIO AND PROPORTION. First, we'll need to set up a proportion to figure out what 7% of 1.42 is. This is the proportion we'll use: x/1.42 = 7/100. Now, let's cross-multiply: 100x = 9.94. Next, we'll divide to figure out what 7% of 1.42 is: x = 0.0994. Lastly, all we need to do is add that value to 1.42 to figure out the total cost: 1.42 + 0.0994 = $1.5194 in total.

GEOMETRY: 
The formula for the circumference of a circle is 2 x pi x radius. Let's plug in the radius to this equation: 2 x pi x 3.1. Now, we need to multiply, first leaving it in terms of pi: 6.2 x pi. The circumference of this circle is 6.2pi or 19.477.

Hope this helps!! :)

Answer:

It's right :)

Explanation:

  • Dilation along the x-axis = (-7-1)/(-1-1) = 2/8 = 1/4
  • Dilation along the y-axis = (-7-1)/(-1-1) = 2/8 = 1/4

Thus, the overall dilation is 1/4

Please help! I attached the question below.
kompoz [17]

Answer:

\frac{2(c+2)}{c(c-2)}

Step-by-step explanation:

\frac{c^{2}-4 }{6c^{4}+15c^{3}}=\frac{(c-2)(c+2)}{c(6c^{3}+15c^{2}) }

Identity used:

a^{2}-b^{2}=(a-b)(a+b)

\frac{c^{2}-4c+4}{12c^{3}+30c^{2}}=\frac{(c-2)^{2}}{2(6c^{3}+15c^{2}) }

Now let us divide the modified expressions:

\frac{(c-2)(c+2)}{c(6c^{3}+15c^{2})} ÷ \frac{(c-2)^2}{2(6c^{3}+15c^{2}) }

we get:

\frac{2(c+2)}{c(c-2)}
