The time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds

Given the equation representing the height reached by a rocket as:

y = -16x^2 + 157x + 104

The rocket will hit the ground when y = 0. Substituting y = 0 into the expression to get x;

0 = -16x^2 + 157x + 104\\16x^2 - 157x - 104 = 0\\

On factorizing:

x = 10.43 seconds

Hence the time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds

X^2-3=5x simplify this
Alex Ar [27]
To simplify x^2-3 =5x

You would first subtract 5x from both sides

X^3-5x-3

Next you would plug this into the quadratic equation:

X=5+/- the square root of: -5^2 -4(1)(-3)/2(1)

Then simplify,
5+/- the squareroot of 24 + 12 / 2

5+/- The squareroot of 36 /2

5+/- 6 / 2

Then solve if it’s an addition or subtract

5+6/2

X=11/2 or 5 1/2

5-6/2

X= -1/2

The answer is x=-1/2 or x=11/2

Hope this helps

Andrew's sanwich consists of a 20-gram piece of cheese, a 60-gram piece of Turkey, and two 30-gram slices of bread. What is the
Maru [420]

Answer:

0.14

Step-by-step explanation:

The way to solve this problem is to add everything together. 20+60 is 80, and there are two 30 gram slices of bread (30 x 2 = 60) so you add the 80 from before to the two slices of bread, which is 80 + 60, and that equals 140 grams total. Since there are 1000 grams in 1 kilogram, you have to divide this by 1000, giving you 0.14 or 14/1000.
