4f(2)=4×5/2=10
g(10)=10×(10+1)²=1210
so the answer is d.
your description is different from the picture. what i answered was the question in the picture.
Answer:
The estimated product is 12.
Step-by-step explanation:
When rounding fractions, we can round them to 0, 1/2 or 1. 6 4/11 can be rounded to 6 since 4/11 isn't near the half of 11. 2 1/12 can be rounded to 2 since 1/12 is obviously close to 0. 6 x 2 = 12. The estimated product is 12.
3x - 1 = 3x -1 because it's reflecting itself
The generic equation of the line is:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
Substituting values:
m = (20-15) / (10-5)
m = (5) / (5)
m = 1
We choose an ordered pair:
(xo, yo) = (5, 15)
Substituting values:
y-15 = 1 (x-5)
y = x - 5 + 15
y = x + 10
Answer:
An equation of the line that passes through the points (5 15) and (10 20) is:
y = x + 10
Area of the sector is 981.3 cm²
Step-by-step explanation:
- Step 1: Find the area of the sector where radius = 50 cm and central angle = 45°
Area of the sector = πr² (C/360), where r is radius and C is the central angle
⇒ Area = 3.14 × 50² × (45/360)
= 3.14 × 2500 × 1/8
= 7850/8 = 981.3 cm²
