Answer:
1) 36
2) 190
3) 72 units
Step-by-step explanation:
1) 2x4 = 8 units area for rectangle
(4-2) x4 /2 = 4 units
6 x 4 = 24 units
8 + 4 + 24 = 36
2) 3 x 10 / 2 = 15 units
5 x 10 /2 = 25 units
15 x 10 = 150 units
150 + 25 + 15 = 190 units
3) 6 x 3 / 2 = 9 units
6 x 9 = 54 units
6 x 3 / 2 = 9 units
9 + 9 + 54 = 18 + 54 = 72 units
Answer:
Stohr sequence
Step-by-step explanation:
Let a_1=1 and define a_(n+1) to be the least integer greater than a_n which cannot be written as the sum of at most h>=2 addends among the terms a_1, a_2, ..., a_n. This defines the h-Stöhr sequence
Answer:
Integers are always closed under subtraction, addition and multiplication, not division though. Hope this helped! :D
Step-by-step explanation:
a=8+2=10; b=4•5=20; c=6-2=4
Answer:
Step-by-step explanation:
An ellipse centered a point (h,k) has the following formula:
The distance between foci is:
![2\cdot c = \sqrt{[8-(-8)]^{2}+(0-0)^{2}}](https://tex.z-dn.net/?f=2%5Ccdot%20c%20%3D%20%5Csqrt%7B%5B8-%28-8%29%5D%5E%7B2%7D%2B%280-0%29%5E%7B2%7D%7D)
The center of the ellipse is:
The known vertex is on the horizontal axis of the ellipse. Then, the length of the semi-major axis is:
The length of the semi-minor axis is given by the following expression:
The equation of the ellipse is:
