Answer:
Yes
Step-by-step explanation:
9x^2-12x+4 can be factored to (3x-2)(3x-2). If you use the FOIL method, 3x times 3x gives you 9x^2, 3x times -2 gives you -6x, -2 times 3x gives you -6x (-6x + -6x gives you -12), and lastly -2 times -2 gives you 4.
Yes it will.
550.2 mph (550 1/5 mph)
x 3.5 hrs (3 1/2 hrs)
= 1925.7 miles
Answer:
y = 10 PLEASE GIVE BRAINLIEST
Step-by-step explanation:
The angles of this triangle should all add up to 180 degrees.
There are 3 angles so 180 ÷ 3 = 60. Each angle will = 60 degrees.
To find y:
5y + 10 = 60
5y = 60 - 10
5y = 50
y = 50 ÷ 5
y = 10
Answer:
Option D (r(t) = 3.50t +25
; r(8) = 53)
Step-by-step explanation:
The fixed cost to rent the kayak $25. This is the cost which remains fixed irrespective of the usage of the kayak. The variable cost of using the kayak is the cost which depends on the usage of the kayak. It is mentioned that the kayak is used for 4 hours and the company charges $3.5 for every half hour. The cost function is given by:
r(t) = 25 + 3.5t ; there r is the total cost of using the kayak and t is the number of half-hours the kayak is used.
4 hours means that there are 8 half-hours. Therefore, t=8. Put t=8 in r(t).
r(8) = 25 + 3.5*(8) = 25 + 28 = 53.
Therefore, Option D is the correct answer!!!
