Answer:

Step-by-step explanation:
we are given a function

we would like to simplify it for h(-1)
in order to do so
substitute the value of x

by order of PEMDAS
simplify square:

reduce fraction:

Combine costs
59.99(3) + 75 = 179.97 + 75
179.97 + 75 = $254.99 (total cost)
Now add tax: 8% = 0.08
254.99 * 0.08 = 20.3992
254.99 + 20.3992 = 275.3892
Solution: bill would be around $275

Step-by-step explanation:
I just did this question on my assignment on Edge 2021
Answer:
125feet
Step-by-step explanation:
Given the equation that modeled the height expressed as h = -16t^2 + 80t + 25, where h is the height and t is the time in seconds.
The arrow reaches the maximum height at dh/dt = 0
dh/dt = -32t + 80
0= -32t+80
32t = 80
t = 80/32
t = 2.5secs
substitute t = 2.5 into the formula;
h = -16t^2 + 80t + 25
h = -16(2.5)^2 + 80(2.5) + 25
h = -16(6.25)+225
h = -100+225
h = 125
Hence the maximum height the arrow reaches is 125feet
Answer:
Step-by-step explanation:
I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.
11) tan45 = x/13 x = 13
cos45 = 13/y y = 13√2
12) sin30 = 4/x x = 8
tan30 = 4/y y = 4√3
13) sin60 = 21/x x = 21(2/√3) = 42/√3
y = xcos60 = (42/√3)(1/2) = 21/√3
14) cos45 = x/22 x = 22/√2
sin45 = y/22 y = 22/√2
15) Height = 24sin30 = 12
cos 45 = 12/x x = 12/√2
tan45 = y/12 y = 12
cos30 = z/24 z = 24(√(3)/2) = 12/√3
