Is BC=2.3 one of the options?
For that question, you can use the cosine rule, where;

In this case, we have..

Solving for BC with this will get you 2.250406, rounded off to the tenth is 2.3.
Answer:
It's the first choice y = (-5/2)x - 1.
Step-by-step explanation:
First find the slope of the line 5x + 2y = 12 by converting to slope-intercept form.
5x + 2y = 12
2y = -5x + 12
y = (-5/2)x + 6 so the slope is (-5/2).
The line we require had also a slope of -5/2 because it is parallel to the first line and it also passes through the point (-2, 4). So:
y - 4 = (-5/2)(x - -2) (the point-slope form)
y - 4 = (-5/2)(x + 2)
y = (-5/2)x - 5 + 4
y = (-5/2)x - 1 (answer)
C. 0.4 times 6 is 2.4. Hope that helps.
This is the answer if you mean 719-26
700-30= 670
Answer:
235.5 cm³
Step-by-step explanation:
Volume of a cylinder is the area of the circular base times the height of the cylinder:
V = π r² h
Given r = 5 cm and h = 3 cm:
V = (3.14) (5 cm)² (3 cm)
V = 235.5 cm³
