Step-by-step explanation:
First, find the zeroes of the parabola







So the zeroes or where the curve crosses the x axis is at 4 and -3.
Now, we take the derivative of the function.

Plug in -3, and 4 into the derivative function


So at x=-3, our slope of the tangent line is -7 and must pass through (-3,0). So we use point slope formula.



At x=4, our slope of tangent line is 7, and pass through (4,0) so


So the equations of tangent is


Answer:
D) 125°
Step-by-step explanation:
FGHJ is congruent to RSTV
So, m∠F = m∠R
∠R = 125
∠F = 125
Answer:
The probability that neither player gets on base is 0.4824
Step-by-step explanation:
1. Both players get to base. <em>Just multiply the two probabilities together</em>:
= (<em>probability first batter gets on base</em>) x (<em>probability second batter gets on base, if the first batter gets on base</em>)
= 0.23 x 0.38
= 0.0874
2. One player gets to base. The formula here is P(A+B) =P(A) + P(B) - P(A) x P(B)
= (<em>probability first batter gets on base</em>) + (<em>probability second batter gets on base, if the first batter does not</em>) - (0.23 x 0.26)
= 0.23 + 0.26 - (0.23 x 0.26)
= 0.49 - 0.0598
= 0.4302
3. Neither player gets to base =<em> 1 - addition of the previous two cases</em>.
= 1 - (0.0874 + 0.4302)
= 1 - 0.5176
= 0.4824
Answer:
8 / 17
Step-by-step explanation:
So cosine is adjacent ÷ hypotenuse.
Adjacent = 8
Hypotenuse = 17
8 / 17
If you divide 530/900 in a calculator you would get 0.58 repeating then ending in a 9
