Answer:

Unit rate is often a useful means for comparing ratios and their associated rates when measured in different units. The unit rate allows us to compare varying sizes of quantities by examining the number of units of one quantity per one unit of the second quantity. This value of the ratio is the unit rate.

The formula for the area of a triangle is A==bh, where b is the length of the base and h is the height.
zimovet [89]

Answer:   Height is 5 units.

Step-by-step explanation:

Alright, lets get started.

The area of the triangle is A=\frac{1}{2} \times b \times h

The area is given as 30

The base is given as 12

Plugging the values in formula

30=\frac{1}{2} \times 12\times h

30=6\times h

Dividing 6 in both sides

\frac{30}{6}=\frac{6\times h}{6}

5=h

h=5

Hence the height of the triangle is 5 units.........Answer

Is the given function phi(x) = x^2 - x^-1 an explicit solution to the linear equation d^2y/dx^2 - 2/x^2 y = 0? Circle your answe
mart [117]

Answer:

Yes

Step-by-step explanation:

We are given that a function \phi(x)=x^2-x^{-1}

We have to find that given function is an explicit solution to the linear equation

\frac{d^2y}{dx^2}-\frac{2}{x^2}y=0

If given function is an explicit solution of given linear equation then it satisfied the given differential equation

Differentiate w.r.t x

Then we get \phi'(x)=2x+x^{-2}

Again differentiate w.r.t x

Then we get

\phi''(x)=2-\frac{2}{x^3}

Substitute all values in the given differential equation

2-\frac{2}{x^3}-\frac{2}{x^2}(x^2-x^{-1})

=2-\frac{2}{x^3}-2+\frac{2}{x^3}=0

Hence, given function is an explicit solution of given differential equation.

Therefore, answer is yes.

A bank requires a monthly payment of $32.88 on a $2500 loan. At the same rate find the monthly payment on a $50,000 loan
Bingel [31]

$ 657.6

Step-by-step explanation:

Step 1:

Given,

Principal = $2500

Monthly payment  = $32.88

Step 2 :

The amount of monthly payment and the principal amount are in direct proportion , that is when the principal amount increases the monthly payment increases and when the principal decreases the monthly payment decreases.

Step 3 :

The monthly payment for $2500 is $32.88

Therefore for a principal of $50000, the amount of  monthly payment is

32.88 *50000/2500 = $657.6
