d₁ = -16t² + 122t

d₂ = -16t² + 84t

d = d₁ - d₂

d =  -16t² + 122t  -  (-16t² + 84t)

d = 38t

After five seconds, t=5,

d = 38(5) = 190

Answer: 190 feet

Slope : - 9/7 point : ( -7,4 )
dolphi86 [110]
To form an equation with the given information, we use the formula :

y = mx + b, m being the slope and b being the y-intercept.

Since it is given that the slope is -9/7, we substitute m with -9/7.

y = -9/7x + b

To find b, we will substitute the known coordinates into the equation :
At point (-7 , 4), x = -7, y = 4

4 = -9/7 (-7) + b
4  = 9 + b
b = 4 - 9
b = -5

Now we know that b = -5, we will substitute b = -5 into the equation that we found earlier, y = -9/7 x + b :

y = - 9/7x - 5

To make it more readable, we can multiply the equation by 7:
7y = -9x - 5
7y + 9x + 5 = 0

-----------------------------------------------------------
Answer : 7y + 9x + 5 = 0

What is the converse of t > r
Anettt [7]

The converse of  t > r is r > t

<h3>What is a converse statement?</h3>

A converse statement is determined when both the hypothesis and conclusion are reversed or interchanged.

In this condition, the hypothesis is written as the conclusion and the conclusion is changed to be the hypothesis.

If a conditional statement is written as: x → y

The converse is then written as y → x

Where;

  • x is the hypothesis
  • y is the conclusion

Given the expression as;

t > r

We can see that;

  • The variable 't' is the hypothesis
  • The variable 'r' is the conclusion

The converse will be;

r > t

Hence, the converse is r > t
