Answer:
z/35 + 5z^2 = 5/35 + 5(5^2) = 1/7 + 5(25) = 1/7 + 125 = 126/7 ≈ 18.00,
Write the equation of the line that passes through (1,3) and (-2,9)
Answer:
y=-2x+13
Step-by-step explanation:
slope equation= (y2-y1)/(x2-x1)
(9-3)/(-2-1)=(6/-3)=-2
slope changes by a factor of -2
y=mx+b ... find b, plug in values
9=-2(-2)+b
9+4=b
b=13
CHECK
9=-2(-2)+13
9=-4+13
9=9
CORRECT

Answer:
is 16.75
Step-by-step explanation:
16 cm
4 cm
8 cm
answer: 8
Explanation:
Use the formula for the area of a circle:
A = π r 2
Here, the area is 16 π
16 π = π r 2
Divide both sides by
16 = r 2
Take the square root of both sides:
√ 16 = √ r 2
4 = r
Since the radius of the circle is
4
, the diameter is twice that:
d = 4 × 2 = 8
