Answer:
D. the slope is -2 and the y-int is (0,1)
Answer:
opens down
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) - (- 10, - 1 ) , then
y = a(x + 10)² - 1
To find a substitute (- 8, - 5) into the equation
- 5 = a(- 8 + 10)² - 1 ( add 1 to both sides )
- 4 = a(2)² = 4a ( divide both sides by 4 )
- 1 = a
y = - (x - 10)² - 1 ← equation in vertex form
To determine if it opens up/ down consider the value of a
• If a > 0 then curve opens up
• If a < 0 then curve opens down
Here a = - 1 < 0 then curve opens down
Answer:6.0002inch
Step-by-step explanation:
Volume of sphere=904.39
π=3.14
Volume of sphere=4/3 xπ x r^3
904.39=4/3 x 3.14 x r^3
904.39=(4x3.14xr^3) ➗ 3
904.39=(12.56xr^3) ➗ 3
Cross multiplying we get
904.39x3=12.56xr^3
2713.17=12.56xr^3
r^3=2713.17 ➗ 12.56
r^3=216.02
Taking the cube root of both sides
r=3√216.02
r=6.0002
