Step-by-step explanation:
The x-coordinate of the vertex is given by ...
x = -b/(2a)
for f(x) = ax^2 +bx +c.
We see that the vertex is at x = 1, and we are given a = -16. Then we can find "b" from ...
1 = -b/(2(-16))
32 = b
We know the y-intercept of the equation is 5 (the starting height), so the equation must be ...
h(t) = -16t^2 +32t +5 . . . . . matches the last choice
We want to solve
4/7 = x/161
Cross multiply.
7x =(4)(161) = 644
Divide each side by 7.
x = 644/7 = 92
Answer: x = 92
Answer:
y-5=11
y-5+5=11+5 (Add 5 to both sides)
y=16 (Simplify)
I believe that y=16 cannot be simplified so y=16 should be the answer let me know if it helped.
Answer:
9
Step-by-step explanation:
3(h-7)+3=9
3h-21+3=9
3h-18=9
3h=9+18
3h=27
h=27/3
h=9

Total possible outcomes of 3 dice = 6 x 6 x 6 = 216
Total number of ways for all 3 to show even numbers:
222
224
226
242
244
246
262
264
266
.
.
etc. There 27 of them.
Probability = 27 / 216 = <u>1/8</u> = 12.5 percent .
