Answer:

\frac{41}{28} = 1\frac{13}{28}

Step-by-step explanation:

In order to add fractions, the denominators must all be the same value (the lowest common denominator). The <em>lowest common denominator</em> is the smallest value that all of the given denominators (in this case, the denominators are 4, 14, and 7) can divide into.

Here, the smallest number that all three of the given denominators can perfectly divide into is 28:

28 ÷ 4 = 7

28 ÷ 14 = 2

28 ÷ 7 = 4

<em>Therefore, our lowest common denominator is 28.</em>

<em />

The next step is to change our numerators to match our lowest common denominator. To do this, we have to multiply the numerator by the same value that we would need to multiple the denominator by in order to get our lowest common denominator.

For our first term of 1/4, we need to multiply our denominator (4) by 7 in order to get our lowest common denominator of 28. So, we need to also multiply our numerator by 7:

\frac{1}{4} × \frac{7}{7} = \frac{7}{28}

<em>Therefore, our first term becomes </em>\frac{7}{28}<em>.</em>

For our second term of 5/14, we need to multiply our denominator (14) by 2. So, we need to also multiply our numerator by 2:

\frac{5}{14} × \frac{2}{2} = \frac{10}{28}

<em>Therefore, our second term becomes </em>\frac{10}{28}<em>.</em>

For our third term of 6/7, we need to multiply our denominator (7) by 4. So, we need to also multiply our numerator by 4:

\frac{6}{7} × \frac{4}{4} = \frac{24}{28}

<em>Therefore, our third term becomes </em>\frac{24}{28}<em>.</em>

Now that they all have the same denominator, we simply have to add all three together:

\frac{7}{28} + \frac{10}{28}<em> </em>+<em> </em>\frac{24}{28}<em> </em>= \frac{41}{28}

When we simplify this into a mixed number, we get:

\frac{41}{28} = 1\frac{13}{28}

<u>ANSWER TO PART A</u>

The given triangle has vertices J(-4,1), K(-4,-2),L(-3,-1)


The mapping for rotation through 90\degree counterclockwise has the mapping


(x,y)\rightarrow (-y,x)


Therefore

J(-4,1)\rightarrow J'(-1,-4)


K(-4,-2)\rightarrow K'(2,-4)


L(-3,-1)\rightarrow L'(1,-3)


We plot all this point and connect them with straight lines.


ANSWER TO PART B


For a reflection across the y-axis we negate the x coordinates.


The mapping is



(x,y)\rightarrow (-x,y)


Therefore

J(-4,1)\rightarrow J''(4,1)


K(-4,-2)\rightarrow K''(4,-2)


L(-3,-1)\rightarrow L''(3,-1)


We plot all this point and connect them with straight lines.

A football is thrown from the stadium. The height of this football can be represented by the polynomial -16t2 +32t + 20, where t
olasank [31]

Answer:

C

Step-by-step explanation:

related equation

-16t^2 + 32t + 20 = 0

-4t^2 + 8t + 5 = 0

Δ/4 = 16 + 20 = 36

t1 = (-4 + 6)/-4 = -1/2

t2 = (-4 - 6)/-4 = 5/2

-16(t+1/2)(t-5/2)

-16(2t+1/2)(2t-5/2)

-4(2t+1)(2t-5)
