Answer:
1280 pages
Step-by-step explanation:
You simply continue the pattern
40 × 2
80 × 2
160 × 2
320 × 2
640 × 2
= 1280
Answer:
True
Step-by-step explanation:
An = a1+d*(n-1)
a11 = 75-8*(11-1) = -5
Excercise 1:
No, this is not simplified fully. The full answer would be <span>−7dk+14d−21k</span>−7, not <span>14d - 9 - 21k - 7dk + 2. So, it is not equivalent.
</span><span>
Excercise 4:
</span><span>7dk (2 - 3 - 1) - 7
</span>
Just multiply 7dk into (2) (-3) and (-1)
you'd get:
<span><span>−<span>14dk</span></span>+</span>−<span>7 after simplifying it fully.
</span>
p = parameter
w = width
w+2.75
p = 2w+2(w+2.75) = <span>4w</span>+<span>5.5 = 30
Answer to the last one:
w = 6.125</span>
The mid-point for given endpoints is (4,3)
Step-by-step explanation:
a mid-point is the point on a line segment that divides it into two equal portions.
If (x1,y1) and (x2,y2) are the coordinates of vertices of a line segment, then mid-point is given by:
![M = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})](https://tex.z-dn.net/?f=M%20%3D%20%28%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%29)
given
(x1,y1) = (9,9)
(x2,y2) = (-1,-3)
![M = (\frac{9-1}{2}, \frac{9-3}{2})\\\\=(\frac{8}{2}, \frac{6}{2})\\\\=(4,3)](https://tex.z-dn.net/?f=M%20%3D%20%28%5Cfrac%7B9-1%7D%7B2%7D%2C%20%5Cfrac%7B9-3%7D%7B2%7D%29%5C%5C%5C%5C%3D%28%5Cfrac%7B8%7D%7B2%7D%2C%20%5Cfrac%7B6%7D%7B2%7D%29%5C%5C%5C%5C%3D%284%2C3%29)
The mid-point for given endpoints is (4,3)
