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.
Area of the figure:
Af = a² + 2 a²/4 π = 2.57 a²
Area of the shaded region:
As = 2 a²/4 π = 1.57 a²
x = (1.57 · 100) / 2.57 = 61 % ≈ 60 %
Answer: B) about 60 %
Answer:
$5.47
Step-by-step explanation:
Given data:
Annie has 4 dollar , 11 dimes, 4 pennies.
Tommy has 3 dimes, 3 pennies.
To add the money, let us first convert dime and penny into dollar.
1 dollar = $1
11 dime = $1.1
4 penny = $0.04
3 dime = $0.3
3 penny = $ 0.03
Total money = Annie’s money + Tommy’s money
= $4 + $1.1 + $ 0.04 + $0.3 + $0.03
= $5.47
So, they have $5.47 in all.
Answer
C. 14
Explanation
The area of triangle = 1/2(base)(height)
The height:
the height is the distance from point (2,-3) perpendicular to the base intersecting it at point (2,1)
the height is then the distance between the 2 points = 4
The base:
the base is the distance between points (7,1)and (0,1) = 7
The area:
the area = 1/2 x 4 x 7 = 28/2 = 14 units²
Answer:
The answer is 5.
