Answer:
2.5 times z = 10, or 2.5<em>z </em>=<em> </em>10
Step-by-step explanation:
Answer:
about 26.6 times
Step-by-step explanation:
The circumference of the ball is found from ...
C = 2πr = 2π(4.3 in) ≈ 27.02 in
There are 12 inches per foot, so the 60 foot distance of interest is ...
(60 ft)×(12 in/ft) = 120 in
In terms of ball circumference, that distance is ...
(120 in)/(27.02 in/rotation) ≈ 26.6 rotations
If the ball starts rotating at the foul line, it will turn about 26.6 times before reaching the head pin.
Answer:
The discriminant D=0
Step-by-step explanation:
For the duadratic polynomial
the discriminant is

In your case, for the polynomial 
<span>2x^2-x=3
</span><span>2x^2-x - 3 = 0
</span><span>(2x - 3)(x + 1) = 0
2x - 3 =0
x = 3/2
x + 1 =0
x = -1
answer
</span>
x = -1 and x = 3/2
Answer:
f(g(3)) = 26
Step-by-step explanation:
f(g(3))
g(3) = 2x + 3
= 2(3) + 3
= 6 + 3
= 9
f(9) = 3x - 1
= 3(9) - 1
= 27 - 1
= 26
