Answer:
3 hours.
Step-by-step explanation:
Since they are heading away from each other, their relative velocity is 60+55 = 115 mph. 345 miles/115 mph = 3 hours.
Check by plugging in. In 3 hours, Max travels 3 * 60 mph = 180 miles from the starting point. Min travels 3 * 55 mph = 165 miles in the other direction from the starting point. The total distance is 165 + 180 = 345 miles.
Answer:
5 mph.
Step-by-step explanation:
Let the runner travel at x miles an hour , then the cyclist travels at 5/ 3 * x
= 5/3 x miles an hour.
So we have the equation
5/3 x - x = 2 ( since the cyclist was travelling at 2 mph faster).,
2/3 x = 2
x = 3/2 * 2 = 3 mph.
So the cyclists speed was 3 * 5/3
= 5 mph.
Answer:
0 or 1
Step-by-step explanation:
Hello, first of all we need x positive so that is defined and then
Thank you
The constants of a polynomial is the term that has no variable attached to it.
<h3>The constant term</h3>
To determine the constant, we simply multiply the constant term in each factor of the polynomial.
So, we have:
<h3 /><h3>Polynomial P(x) = (x-2)(x-4)(x-5)</h3>
Hence, the constant is -40
<h3>Polynomial P(x) = (x-2)(x-4)(x+5)</h3>
Hence, the constant is 40
<h3>Polynomial P(x) =1/2(x-2)(x-4)(x+5)</h3>
Hence, the constant is 20
<h3>Polynomial P(x) = 5(x-2)(x-4)(x+5)</h3>
Hence, the constant is 200
<u>P(x) =-5(x-2)(x-4)(x+5)</u>
Hence, the constant is -200

Answer:
The surface area of the rectangular prism is 52 square feet (ft²), if the height is 4 feet, width is 3 feet and depth is 2 feet.
Step-by-step explanation:
The given is,
A prism of
Let, h - height of the prism
w - Width of the prism
d - Depth of the prism
Step:1
From given,
h = 4 feet
w = 3 feet
d = 2 feet
Step:2
Formula to calculate the surface area of the rectangular prism is,
A=2(wd+hd+hw)
Substitute the values of w,d and h
= 2 [(3×2) + (4×2) + (4×3)]
= 2 (6+8+12)
= 2 × 26
= 52
A = 52 Square feet
Result:
Thus the surface area of the rectangular prism is 52 square feet (ft²), if the height is 4 feet, width is 3 feet and depth is 2 feet.
