Mathematics
1 answer:
arlik [135]3 years ago
6 0

Answer:

Step-by-step explanation:

a = 5

r = -5

n = 9

t_9 = a r^(n - 1)

t_9 = (-1)^n*5 (-5) ^ 8

t_9 = (-1)^9 *  5 *  (-5) ^8

t_9 = -1 ( 1953125)

t_9 = - 1953125

Fantom [35]

Your trying to rearrange the equation with v were the r was.

2( v - h ) / k = r

2( v - h ) k / k = rk

2( v - h ) = rk

2( v - h ) / 2 = rk / 2

v - h = rk / 2

v - h + h = rk / 2 + h

v = rk / 2 + h

The smallest integer that can be added to -2m3 − m + m2 + 1 to make it completely divisible by m + 1 is .
Iteru [2.4K]

Answer:

(-5) is smallest integer to be added.

Step-by-step explanation:

In the given expression we have to identify the smallest integer to be adeed so that it is divisible by (m+1).

If we divide the expression then we get quotient (-2m²+3m-4) and the remainder is +5.

Therefore we can say that if we subtract 5 from the given expression it will be divisible by (m+1).

So the answer is (-5) is the smallest integer to be added.

The diagram shows 5 ft student standing near a tree. The shadow of the student and the shadow of the tree
mariarad [96]

Answer:

x = 25 ft

Step-by-step explanation:

here we see the student standing and creating a small triangle that is equivalent to the big triangle since it has the same angles, the only difference is that its smaller, so what we have to do is make a proportion of both triangles, so since 8 ft correspond with the 40 ft they're going to be in the same part of the proportion and the other measurements, including x, on the other part, so itll be 5/8 and x/40, see how the 8 and 40 are both on the bottom? thats because they correspond, so now all you have to do is cross butterfly, so you can set up an expression on 8x= 5*40 or you can just multiply 5*40 and then divide by 8, your answer will be x= 25 ft
