Since the ideal width is 7 cm and can vary by most 0.3 cm. This means the range is 6.7 cm to 7.3 cm Absolute value means that any negative number becomes positive. l 6.7 -7 l and l 7.3 - 7 l both equal 0.3 cm
l w - 7 l </= 0.3
I believe your answer is 6 seconds.
Because the height of the ball = -16(x² - 5x - 6), when the height of the ball is 0, which is when it is on the ground, we can set -16(x² - 5x - 6) equal to 0. This also allows us to divide by -16, and then we can solve the equation:
x² - 5x - 6 = 0
(x - 6)(x + 1) = 0
So x = 6 or x = -1, and because a quantity of time cannot be negative, x would have to be 6, which means it takes 6 seconds for the ball to reach 0 feet.
I hope this helps!
Answer:
∠ U = 60°
Step-by-step explanation:
The tangent- tangent angle U is half the difference of its intercepted arcs
minor arc VT = 120° , then
major arc VT = 360° - 120° = 240°
Then
∠ U = 
(240 - 120)° = × 120° = 60°
1/10 * 4/10 = 4/100 divide both by 4 it'll be 1/25
