Question 2 and explanation

2. Now, to make sure that 1/6 is the correct rule, we do have to go back to the first two fractions and give them common denominators: 1/2 turns into 3/6, and 2/3 turns into 4/6.

3. No once you look at your fractions, you can see that 1/6 is the true rule.

4. Now that we know t he rule we can turn to completing the unknown term. Since we are only moving by 1/6 it makes it very easy to add that 1/6 to your 4/6 to get 5/6. You can't simplify 5/6, so your final answer for the unknown term is 5/6.

Hope this helps :)

Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/sWhen Sharon jumps, Megan throws a beach

likoan [24]

Answer:

1.08 seconds

Step-by-step explanation:

given data

first equation:

According to the data, sharon position will be

h(t)= -16 $t^{2}$ + 4t +18---->eq(1)

Second equation;

When Sharon jumps, Megan throws a beach ball up to Sharon with an initial upward velocity of 16 ft/s from a height 5 feet off the ground to the nearest hundredth of a second

therefore, ball position would be

h(t)= -16 $t^{2}$ +16t +5 --->eq(2)

In order to find how long after she jumps does the ball reach Sharon i.e time, we will equate eq(1) and eq(2)

Therefore,

eq(1)= eq(2)

-16 $t^{2}$ +4t +18 = -16 $t^{2}$ + 16t +5 --->(further simplifying it)

-16 $t^{2}$ + 16 $t^{2}$ + 18 -5 = 16t - 4t

13 = 12t

t= 13/12

t= 1.08 s

Thus it took 1.08 seconds.

What type of polynomial is 3x+x to the second power +4

mina [271]

The answer is quadratic.

A quadratic equation takes this form:

ax^2+ bx + c

The "a,""b,"and "c" represent numerical coefficients.

This is how your equation looks:

3x + x^2 + 4

Now it is standard that we organize the polynomial in descending order so it will look like this:

x^ 2 + 3x + 4

(commutative property of addition says that the arrangement will not affect the result)

It matches the quadratic polynomial form.

* You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed.
