Answer:
DFBG
Step-by-step explanation:
At any point in time;
slope m = (y2-y1)/(x2-x1)
1. (3,19) and ((-1,-13)
m = (-13-19)/-1-3 = -32/-4 = 8
Letter here is D
2. we pick out two points to use here from the line
These are ((0,1) and (2,5)
Slope is ;
(5-1)/2-0 = 4/2 = 2
Letter here is F
3. We pick any two points
(1,-8) and (4,-32)
slope =
(-32 + 8)/4-1 = -24/3 = -8
Letter here is B
4. Slope = 8 + 10/0-9 = 18/-9 = -2
letter here is G
If by "long leg lengths" you mean the hypotenuse then the area is 116 sq. units. If you mean the bases of the triangles then the area is 170 sq. units.
If the length of 12 is the hypotenuse, we first must find the base of the triangles using the Pythagorean theorem:
10² + b² = 12²
100 + b² = 144
b² = 44
b = √44 = 6.6
This means we have two triangles and a rectangle. The area of the rectangle is 5(10) = 50 sq. units. The area of each triangle is 1/2(6.6)(10) = 33. Adding all 3 together we have:
50+33+33 = 116 sq. units.
If the 12 is the base, then we have the rectangle with the area of 5(10) = 50 and two triangles each with an area of 1/2(12)(10) = 60:
50+60+60 = 170 sq. units.
(2,-1)(5,-10)
slope = (-10 - (-1) / (5 - 2) = -9/3 = -3
y = mx + b
slope(m) = -3
use either of ur points....(2,-1)...x = 2 and y = -1
now we sub and find b, the y int
-1 = -3(2) + b
-1 = -6 + b
-1 + 6 = b
5 = b
so ur equation is : y = -3x + 5 <==
Multiply 18 ×6 then multiply 4×6 then take the answer of 4×6 and take it away from 18×6
Answer:
A. People who are related to the employees of Isaac's Immaculate Ice Cream
Step-by-step explanation:
If the results are called into question, this means there is potential bias in the survey.
Randomly choosing people from a phone book or another random method would not create bias.
Having people blindly test brands of ice cream would not create bias, as it is random and fair.
However, if the people surveyed were related to employees of Isaac's Immaculate Ice Cream, the results could be called into question over a fear of favoritism.
