The ball will hit the ground when h(t)=0 so:
-16t^2+10t+100=0
Using the quadratic equation:
t=(-10±√6500)/-32, and since t>0
t≈2.8 seconds (to nearest tenth of a second)
It would be A, Side Angle Side (SAS). Because you are given we congruent sides, and tow right angles. Using the reasoning of "If two two angles are both right angles then they are congruent" you can prove the angles congruent.
The reason it is not HL is because HL is used when it is given a right angle and the hypotenuse and one of the legs congruent. Therefore the only choice is Side Angle Side (SAS).
Each ticket is 6 dollars because 5×6= 30 so multiply 7×6
Answer: x=3
Step-by-step explanation:
To find the zeros, you want to first factor the expression.
x³+x²-36
(x-3)(x²+4x+12)
Now that we have found the factors, we set each to 0.
x-3=0
x=3
Since x²+4x+12 cannot be factored, we can forget about this part.
Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
Answer:
$19.50
Step-by-step explanation:
Multiply $2.50 by 4, which will give you $10.00.
Then, add $9.50 and $10 together, which gives you. a total of.
$19.50
