So in 6 months (1/2yr) you earned $15.75 interest, if we double that we find the total interest you would gain for that year, 15.75x2= $31.5 total interest for that year.

To find the annual rate divide the interest gained by the amount deposited, 31.5/500 = 0.063% p.a.

chubhunter [2.5K]

Answer:

Pythagorian theorem:

7^2=13+b^2 -> b^2=49-13=36

The square root of 36 is obviously 6.

So, the other leg has a length of 6 inches

Match the graph of the function with the function rule.
mylen [45]

Answer:

y = 10( {4}^{x} )

Step-by-step explanation:

From the given exponential graph, the y-intercept is (0,10).

The only exponential function that, has this intercept is

y = 10( {4}^{x} )

Because when x=0, we obtain:

y = 10( {4}^{0} )

Simplify:

y = 10(1) = 10

Donte simplified the expression below. 4 (1 3 i) minus (8 minus 5 i). 4 3 i minus 8 5 i. negative 4 8 i. what mistake did donte
SCORPION-xisa [38]

Donte did a mistake that 'he did not apply the distributive property correctly for 4(1 3i)' option (A) is correct.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have an expression:

= 4(1 + 3i) – (8 – 5i)

= 4 + 12i - 8 + 5i  

He did not distribute the subtraction sign correctly for 8 – 5i.

= -4 + 17i

Thus, Donte did a mistake in that 'he did not apply the distributive property correctly for 4(1 3i)' option (A) is correct.
