Answer:

144%

Step-by-step explanation:

There are multiple ways to do this but here's the way I used:

2.50/100 = .025

Based on this, 1% of 2.50 is 0.025.

6.10-2.50 = 3.6

3.6/0.025 = 144

Based on this, 3.4 is 144 times greater than 0.025 (1%). So 3.4 is a 144% increase.

The volume of a rectangular prism is b3 + 8b2 + 19b + 12 cubic units, and its height is b + 3 units. The area of the base of the
omeli [17]
Given:

The volume of the rectangular prism is 

b^{3}+8 b^{2} +19b+12,

the height is h=(b+3)

1. The volume of a rectangular prism is (base area)*height

also, notice that the volume is a third degree polynomial, the height is a 1st degree polynomial, so the base area must be a 2nd degree polynomial, whose coefficients we don't know yet.
Let this quadratic polynomial be (mb^{2}+nb+k)

 
2

b^{3}+8 b^{2} +19b+12=(mb^{2}+nb+k)*(b+3)


notice that  b^{3} is the product of the largest 2 terms: mb^{2} and b, so m must be 1

also, notice that 12 is the product of the constants, k and 3

so k*3=12, this means k=4

3
we write the above equality again:

b^{3}+8 b^{2} +19b+12=(b^{2}+nb+4)*(b+3)


(b^{2}+nb+4)(b+3)= b^{3}+3 b^{2} +nb^{2}+3nb+4b+12

== b^{3}+(n+3)b^{2}+(3n+4)b+12


4
now compare the coefficient with the left side:

8 b^{2}=(n+3)b^{2}

8=n+3

n=5


substituting n=5: 

the base area is b^{2}+5b+4

Answer: b^{2}+5b+4

Calculate the force created from an object with a mass of 1250 grams and an acceleration of 3 m/s^2
abruzzese [7]

The force created by the object is 3.75 Newton.

Given

Mass of the object (m)  = 1250 grams

Convert 1250 grams to kilograms by dividing it by 1000.

Mass (m) = 1.25 kg

Acceleration of the body (a) = 3 m/s^{2}

From Newton's second law we know F= m *a

By Substituting in the above equation we get

Force = 1.25 x 3

Force = 3.75 kg/m /s^{2}

It can also be written as force = 3.75 N

Hence Force created by the body is 3.75 Newton.
