Answer:
B) −1/4
Step-by-step explanation:
The slope represents the change in y values divided by the change in x values. We can use the formula
slope = (y2-y1)/(x2-x1)
(2,4) (-2,5)
slope = (5-4)/(-2-2)
= 1/-4
slope = -1/4
Tenths is after the decimal so the tenths is 5.
ANSWER
56.1 square inches.
EXPLANATION
The area of this triangle can be calculated using the formula,

where a=8in.
b=14.2 in.
and C=99° is the included angle.
We plug in these values to obtain,


We round to the nearest tenth to get,
56.1 sq. inch
Let d(x) = 2x - 4
Or
y = 2x - 4
We have replace x = y
x = 2y - 4
Now Isolate "y"
x + 4 = 2y
Pass "2" dividing
(x + 4) / 2 = y
y = x/2 + 2
Or
d(x)^-1 = x/2 + 2
Answer:
~15 meters away
Step-by-step explanation:
c^2 = a^2+b^2
c^2 = 10^2+11^2
c^2 = 100+121
c^2 = 221
c = 
c = ~15
