Its 100 because its not rounded to the nearest whole like 200 because its less than 50 so it would round down
Answer:
1) -1
2) 3
3) 5
4) 9
Step-by-step explanation:
Plug the numbers in one at a time.
1) y= 2(-2)+3= -4+3= -1
2) y= 2(0)+3= 0+3= 3
3) y= 2(1)+3= 2+3= 5
4) y= 2(3)+3= 6+3= 9
Area of a circle can be calculated using the following formula
Area = πr²
where π = 3.14 and r - radius of circle
Area of the whole circle is for a central angle of 360°.
We are asked to find the area of a sector. Sector is when 2 arms enclose a central angle by which one arm has rotated.
1 radian = 57.3°
2.4 radian = 57.3 x 2 = 137.52°
Area for 360° = πr²
area for 137.52° = πr² / 360° x 137.52 = π x 6 cm x 6 cm x 0.382 = 13.752 cm²
Answer:
2 cm (Answer B)
Step-by-step explanation:
This is a right triangle, and therefore the Pythagorean Theorem applies:
(shorter leg)² + (longer leg)² = (hypotenuse)²
In this case, (longer leg)² = (hypotenuse)² - (shorter leg)², or
(longer leg)² = (13 cm)² - (5 cm)², or:
(longer leg)² = 169 cm² - (25 cm²) = 144 cm²
The length of the longer leg is the square root of 144 cm², or 12 cm (Answer B)
