The time taken for landscaper 1 is 5.4 hours.

The time taken for landscaper 2 is 3.6 hours.

Step-by-step explanation

Let the time taken by the landscaper 1 to complete the job be 'a'

Let the time taken by the landscaper 2 to complete the job be 'a/1.5'

a + (a/1.5) = 9

(1.5a + a) /1.5 = 9

2.5a/1.5 = 9

5a/ 3 = 9

a = 27/5

a = 5.4 hours

a/1.5 = 5.4/1.5

a/1.5 = 3.6 hours

The time taken for landscaper 1 is 5.4 hours.

The time taken for landscaper 2 is 3.6 hours.

"Five" = 5

"times" means multiplication

"a number" = <em>n</em>

"plus" means addition

"3" = 3

"is" means equal

"12" = 12

An object is launched with a velocity at 64 feet per second from a platform 30 feet high. the function H(t)= -16t2+64t+30 repres
PolarNik [594]
To find the maximum or minimum value of a function, we can find the derivative of the function, set it equal to 0, and solve for the critical points.

H'(t) = -32t + 64

Now find the critical numbers:

-32t + 64 = 0

-32t = -64

t = 2 seconds

Since H(t) has a negative leading coefficient, we know that it opens downward. This means that the critical point is a maximum value rather than a minimum. If we weren't sure, we could check by plugging in a value for t slightly less and slighter greater than t=2 into H'(t):

H'(1) = 32

H'(3) = -32

As you can see, the rate of change of the object's height goes from increasing to decreasing, meaning the critical point at t=2 is a maximum.

To find the height, plug t=2 into H(t):

H(2) = -16(2)^2 +64(2) + 30 = 94

The answer is 94 ft at 2 sec.
