Complete question :
There are 575 fireworks to be shot off in a firework display every minute 12 new fireworks are shot off display write a verbal model and algebraic expression to represent the number of fireworks left to be shot off after t minutes.
Answer:
575 - 12t
Step-by-step explanation:
Given the following :
Total number of fireworks = 575
Number of shots per minute = 12
To calculate the number of fireworks left to be shot off after t minutes, The total number of fireworks already shot after the same time interval t in minutes, is first obtained, this is equivalent to (12*t). The result is then subtracted from the total number of fireworks to be shof off.
In algebraic terms
[total number of fireworks on display - (number of shots per minute × t)]
575 - 12t
Answer:
(5x + 40), (7x + 8), (10x)

Hey there!
Formula: πr^2
r = radius
pi = 3.1415926535898 (but we can say it approximately equals 3.14)
Your equation (3.14)(4.2)^2 = answer
4.2^2 = 4.2 × 4.2 = 17.64
New equation: 17.64 × 3.14 = 55.3896
We round our answer to the nearest tenth
Answer: 55.4 ☑️

Answer:
60.
Step-by-step explanation:
(x^2 - 25) / (√(x + 4) - 3).
We rationalise the expression by multiplying top and bottom of the fraction by the complement of the denominator.
That is by (√(x + 4) + 3):
(x^2 - 25)(√(x + 4) + 3)
= ------------------------------------
(√(x + 4) - 3)(√(x + 4) + 3)
= (x + 5)(x - 5)(√(x + 4) + 3)
----------------------------------
(x - 5)
= (x + 5)(√(x + 4) + 3).
The limit as this---> 5
is (5 + 5)(√(5 + 4) + 3)
= 10 * 6
= 60.
