Answer:

<h3>The answer is 4.9cm</h3>

Step-by-step explanation:

To find the perpendicular distance between them that's the height we use the formula

Area \:  \: of \:  \: a \:  \: trapezium =  \frac{1}{2} (a + b) \times h

where

a and b are the parallel sides of the trapezium

h is the perpendicular distance

From the question

Area = 31.5cm²

a = 7.5 cm

b = 5.3 cm

Substituting the values into the above formula we have

31 .5 =  \frac{1}{2} (7.5 + 5.3) \times h

31.5 =  \frac{1}{2}  \times 12.8h

31.5 = 6.4h

Divide both sides by 6.4

h =  \frac{31.5}{6.4}

h = 4.921875

We have the final answer

<h3>h = 4.9cm</h3>

check the first picture below.


those are the table of values we get for both, at 1 through 5 seconds.


why are both functions equal between the 4th and 5th second?


h(t) is the distance from the ground, check the second picture below, that's pretty much the graph of h(t)  usually.


g(t) is the height of the object from the ground.


whilst g(t) is ever increasing, h(t) goes up, reaches a peak point, the vertex, and then goes back down, on its way down, it drops to 69 and then to 0 at the 5th second, however, between 69 and 0, it dropped first to 31 at some time, and then 30, then 29, then 27, then 25.8 and so on till it got to 0.


one of those values between 69 and 0, will match a value between 25.8 and 31.


what does all that mean in this context?


it means that at some point the baseball was at a height predicted g(t) as well as by h(t).

How do you Simplify 3/12?
densk [106]
You need to find a number that can go into both 3 and 12. 3 can go into 3 and 12. So, you would then find out, how many times does 3 go into this number? Well, 3 goes into 3 once of course, and 3 goes into 12 four times. (3 x 4 = 12) In a fraction, this would be 1/4. (1/4 is the simplification of 3/12)

Would appreciate if someone helped me with this.
zimovet [89]

Answer:

x=4

Step-by-step explanation:

5x + 33 = 18x-30 + 11

Add the numbers

5x + 33 = 18x-19

Subtract 33 from both sides of the equation

5x + 33-33 = 18x-19-33

5x=18x-52

Subtract 18x from both sides of the equation

5x-18x = 18x-52-18x

-13x = -52

-13x/-13 = -52/-13

x=4
