Answer:
18.03
Step-by-step explanation:
So first David went 200m west. I drew a line that went to the west. Next he went 125m north. I drew a line that went north. The question is asking you how far away he is from his starting point. I drew a triangle and connected those two points from where he began. So to find the length or missing side, you need to use an equation known as the pathaegorean theorem. A²+ B²+ C². 125+200 is 325. The square root of 325 is 18.0277. However, they ask us to round to the nearest hundredth. So that number would you round to 18.03 ( since the seven makes the two go up).
Option A). 7, -4 and 1/3
To find the zeros you can factor the polynolial into (3x-1)((x+4)(x-7)
Then:
3x -1 =0 => x = 1/3
x+4=0 => x = -4
x-7 =0 => x =7
Those are the three zeros.
Answer:
a. x is equal to 54.5
Step-by-step explanation:
The interior angles of a pentagon will add up to 540. Since it is a regular pentagon, each angle would be 108 degrees. So we can set the value of the angle to 108 and solve for x.
2x - 1 = 108
2x = 109
x = 54.5
It is A and D because as you can see it is using subtraction and multiplication and I’m sorry if I am wrong I can’t see much
3, 5 and 7 are three prime numbers. The least common multiple of prime numbers is simply the product of the numbers themselves: so you have
