Answer:

Yearly interest rate would be 6.3%

Step-by-step explanation:

Since, the amount formula of an investment after t years is,

A=P(1+\frac{r}{n})^{nt}

Where,

Expression (1+\frac{r}{n})^{nt} represents change factor in the investment,

In which, r = annul rate or yearly interest rate,

n = number of compounding periods,

t = number of years,

If change factor is (1.021)^{3t} or (1+0.021)^{3t}

Then,

By comparing,

\frac{r}{n}=0.021, n = 3

\implies r = 3\times 0.021= 0.063 = 6.3\%

Hence, yearly interest rate would be 6.3%

Answer:

\huge\boxed{\sf No}

Step-by-step explanation:

<u>The ordered pairs for the given relation are:</u>

=> {(6,2)(-1,2)(-1,-1)(4,3)}

Domain => x-inputs of the ordered pairs

Domain => (6,-1,4)

Range => y-inputs of the ordered pairs

Range = (2,-1,3)

Since, <em>the values in the domain (-1) are being repeated, this relation is not a function.</em>

(A rectangular prism has a length of 1 1/4 yards, a width of 2 1/2 yards, and a height of 4 yards.
slega [8]

Answer:

Step-by-step explanation:

It is given that A rectangular prism has a length of 1\frac{1}{4}yards a width of 2\frac{1}{2} yards, and a height of 4 yards.

Now, the volume of the prism is given as:

V=Length{\times}width{\times}height

V=\frac{5}{4}{\times}\frac{5}{2}{\times}4

V=\frac{25}{2}

V=12\frac{1}{2}cubic yards

Therefore, the volume of the rectangular prism will be V=12\frac{1}{2}cubic yards.
