Answer:
It will take 8 years.
Step-by-step explanation:
If the plant is already 14 inches and you want it to grow up to 38, then we subtract 14 from 38 and then divide the answer by 3 because in each year the plant will grow 3 inches, so then you get 8, which is the numbers of years.
38 - 14 = 24
24/3 = 8
You can use either the quadratic formula or you can factor it.
3Y(y+8)=0
so 3Y=0 Y=0
Y+8=0 Y=-8
3. Hypotenuse 8m, the usual 45/45/90 triangle sides in ratio 1:1:√2. So we're 8/√2 = 4√2 from the wall.
Answer: 4√2 meters
4. 30/60/90 right triangle, sides in ratio 1:√3:2. Hypotenuse 50m, we're after the side opposite 60, so 50/√3 = (50/3) √3
Answer: (50/3)√3 meters
5. 45/45/90 again, ratio 1:1:√2. Leg 3 cm so hypotenuse 3√2
Answer: 3√2 cm
6. The altitude divides the triangle into two 30/60/90 triangles, ratio 1:√3:2.
The side length s of the original equilateral triangle is the hypotenuse and the altitude h is the long leg, so h= (√3/2) s.
Answer: a. 3√3 cm b. 2√3 cm c. 5√3 cm
The mean absolute deviation is the average distance between each number, and the mean, so the answer is 2.4 Hope this helps.
