No solution for the quadratic equation because of the √-20
Answer:
Option (B)
Step-by-step explanation:
From the given table,
With the increase in the values of x (from x = -2 to x = 2), values of the function is decreasing from x =2 to x = 4.
Interval (0, 1) lies in the domain of the function in which the y-values of the function are,
At x = 0,
f(0) = -6
At x = 1,
f(1) = 0
Therefore, values of the given function are increasing in the interval of (0, 1).
Option (B) will be the correct option.
Answer:
<h2> 341 m²</h2><h2 />
Step-by-step explanation:
surface area of a square base pyramid = base area + 4 ( triangular sides area)
where:
base = 11 m
side height length = 10 m
Surface area = 11² + 2(11)10
= 121 + 220
= 341 m²
Y = mx + c
gradient = -6-9/-8-4
= -15/-12
= 1.2
when x = 4 and y = 9,
9 = 1.2(4) + c
c = 9 - 4.8
= 4.2
The slope of the line is y = 1.2x + 4.2 .
