The solution to the problem is as follows:
<span>
the genaral term is 5Cr(-1)^r 2^r x^(5-2r)
and so need 5-2r = -1 => r = 3
Coeff is then 5C3 (-1)^3 2^3 = -80

<span>(2) y is the total cost, x is the number of months of service, $40 is the installation fee, and $90 is the service charge per month.</span>
y = 40 + 90x
y = total cost
x = number of months of service
40 = one time installation fee
90 = monthly service charge.
Let us assume that the number of months of service is 10 months. then, the total cost would be:
y = 40 + 90(10)
y = 40 + 900
y = 940
Answer:
A. 10 cm
Step-by-step explanation:
In a right angled triangle, a² + b² = c² where c is the diagonal or hypotenuse. If you split a rectangle diagonally into two right angle triangles, the a and b of both triangles would be the same length. Therefore, the c or diagonals would also be the same length - 10 cm.
Hope this helps!
Answer:
c
Step-by-step explanation:
4 times 5 is 20 and 20 times 6 is 120
Answer:The larger is 28, the smaller is 9.
Step-by-step explanation:
n = the smaller
3n + 1 = the larger
n + (3n + 1) = 37
4n + 1 = 37
4n = 36
n = 9
3n + 1 = 3(9) + 1 = 28
The larger is 28, the smaller is 9.
