Answer:
d
Step-by-step explanation:
A segment joining the midpoints of a triangle is
• Parallel to the third side
• Half the length of the third side
The segment DF joins the midpoints of 2 sides of Δ ABC , then
BC = 2 × DF = 2 × 4 = 8
Answer:The blue line is the tangent line that passes through the point (0.75, 0.25). The point on the tangent line is (3, 4). The gradient of the curve is approximately 0.6. Note: Parallel lines have the same gradient.
Step-by-step explanation:
Answer: 253.5
Step-by-step explanation:
If your equation is 6s^2, all your doing is:
6x6.5^2,
or the long-form
(6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) = 253.5
1/4 exact form, 0.25 decimal form.
Answer:

Step-by-step explanation:
To find the inverse function, solve ...
x = f(y)
x = (y^7)/7 -4 . . . . . . . use the definition of f(x)
x +4 = (y^7)/7 . . . . . . add 4
7(x +4) = y^7 . . . . . . multiply by 7
(7(x +4))^(1/7) = y . . take the 7th root
The inverse function is the one shown in the attachment.
