Answer:
Height of the ball after 3 seconds = 27.4 feet.
Step-by-step explanation:
h(t) = -4.9t^2 + 22t + 5.5
h(3) means the height of the ball at time 3 seconds after the ball was thrown.
h(3) = -4.9(3)^2 + 22(3) + 5.5
= 27.4 feet
Whats the question that you have and remember theres always google
(x+2)^6
=(x^2+4x+4)(x+2)^5
=(x^3+6x^2+12x+8)(x+2)^4
=(x^4+6x^3+24x^2+32x+16)(x+2)^3
=(x^5+8x^4+36x^3+80x^2+80x+32)(x+2)^2
=(x^6+10x^5+52x^4+152x^3+240x^2+192x+64)(x+2)
=x^7+12x^6+72x^5+254x^4+544x^3+472x^2+448x+164
Answer: x^7+12x^6+72x^5+254x^4+544x^3+472x^2+448x+164
Answer: 20% of 248.00 is the same as 10% + 10% of 248 and the answer is 49.6
So an equation of any line is y=mx+b.
We know that the m, or slope, equals 3.
y=3x+b
Now we find the b, or the y-intercept, by substituting the x and y values into their places.
4=3*1+b
4=3+b
b=1
Now that we have the y-intercept, we just substitute the m and b into the equation and receive our final answer:
y=3x+1
