Find the GCF of the following monomials.<br><br> -50m4n7 and 40m2n10
Dima020 [189]

Answer:

Assuming you are asking for the Greatest Common Factor (GCF) of -50m^4n^7 and 40m^2n^{10} the answer is:

10m^2n^7

Step-by-step explanation:

To find the GCF we should first find the GCF of the coefficients 50 and 40 which is 10.

After factoring that out we need to take a look at the variable m. In monomial 1 we see that the highest exponent of m is 4 and in the second is 2. When finding GCF we take the smallest of the two exponents which is 2. Therefore the next part of our GCF monomial is m²

If we apply the same rule for n the smallest exponent is 7 resulting in the appending of n^{7} to the answer

After combining each of these GCF of 40 and -50 (10), m^4 and m² (m²), and n^7 and n^10 (n^7) the answer is:

10m^2n^7

A theater sells tickets for a concert . Tickets for lower level sells for $35 each , tickets for upper level sell for $25 each .
arlik [135]
150 lower level
200 upper level

Let x = lower level and y = upper level. You can then set up an equation for cost as:

35x + 25y = 10,250

and the equation for total tickets as:

x + y = 350. 

Solve using any method.

A baseball is thrown upward and its height after t seconds can be described by formula h(t)=−16t2+50t+5. Find the maximum height
asambeis [7]

h(t) = -16t² + 50t + 5

The maximum height is the y vertex of this parabola.

Vertex = (-b/2a, -Δ/4a)

The y vertex is -Δ/4a

So,

The maxium height is -Δ/4a

Δ = b² - 4.a.c

Δ = 50² - 4.(-16).5

Δ = 2500 + 320

Δ = 2820

H = -2820/4.(-16)

H = -2820/-64

H = 2820/64

H = 44.0625

So, the maxium height the ball will reach is 44.0625
