Use the quadratic formula where a = -16, b = 175 and c = 500 to find t. See picture for quadratic formula.
Answer:
ABC is not a right triangle
Step-by-step explanation:
The computation is shown below:
AC is
= Perimeter - (AB + BC)
= 22 - (8+5)
= 22 - 13
= 9
Now
= 9^2 + 13^2
= 81 +169
= 250
And, the perimeter is
= 22^2
= 484
Since the amount are not equivalent therefore ABC is not a right triangle
Answer:
G(2) = 2(2) - 8(2) - 10
G(2) = 4-16-10
G(2) = -2
G(5) + 12 = (2(5) - 8(5) - 10) + 12
G(5) + 12 = (10-40-10) + 12
Step-by-step explanation:
G is the function, the number written in brackets in front of it I.e. (5), (2) etc. Is the number you input in the function
Let x be the number of hours it will take for Atu and Brek to meet and cover the total distance of 420. The distance covered is the product of the speed and time. Thus,
56x + 49x = 420
105x = 420
The value of x from the derived equation is equal to 4 hours.
One hour less than the number of hours calculated above is 3 hours. The distances covered are calculated below.
Atu = (56 mph)(3 hours) = 168 miles
Brek = (49 mph)(3 hours) = 147 miles
The total distance covered is equal to 315 miles.
Subtracting this distance from the given total distance.
difference = 420 miles - 315 miles = 105 miles
<em>ANSWER: 105 miles</em>
