Answer:
37.68
Step-by-step explanation:
c = 2 x 3.14 x 6
Hello there, and thank you for posting your question here on brainly.
<em>Short answer: 25.48 x 10^4
</em>
Why?
This equation has a few steps. Simplify the brackets. (2.8 x 10^-2)*(9.1 x 10^6) --> 2.8 x 10^-2 * 9.1 x 10^6 Simplify. (or multiply the two decimals) 2.8 x 10^-2 * 9.1 x 10^6 --> 25.48 x 10^-2 x 10^6 Use the <em>product rule. </em>(the formula is x^y x^z = x^ y+z) 25.48 x 10^-2 x 10^6 --> 25.48 x 10^4
Hope this helped you! ♥
Answer:
Rectangle D is reflected over the x-axis and then translated 8 units right will result in rectangle E
Step-by-step explanation:
The coordinates of rectangle D are:
(-1, 1)
(-1, 4)
(-3, 1) and
(-3, 4)
The rule of reflection across x-axis is given by:
Next, translate this 8 unit right which is given by:
⇒(7, -1) , (5, -1) , (5, -4) and (7, -4) represents the coordinate of rectangle E.
Therefore, Rectangle D if reflected over the x-axis and then translated 8 units right will result in rectangle E
Answer:
x=7
Step-by-step explanation:
Answer:
Step-by-step explanation:
a. The area of a rectangle is width * length. The width is 5x, and the length is 7x-2. This means the area is 5x*(7x-2). Distributing the 5x, we find that the area of the rectangle is 35x^2-10x.
b. To find the area when x is 4, we plug x=4, so 35*4^2-10*4=560-40=520.
c. same as above, we plug x=7, and get 1645 as our area.
