<span><span>anonymous </span> 3 years ago</span>we are solving for A, A is the future amount A=? P is the present value, so we were told 7,900, so p=7900 r is the interest rate, so 4.3%, but in decimal form so r=0.043 k is the how often it is 'compounded', it says quarterly, so k=4 n is how long, 3 years, so n=3 <span>A=P(1+<span>rk</span><span>)<span>n∗k</span></span></span> plug in the values

Find Z1 in trig form z1= (-3+4i)
Eva8 [605]

Answer:

i = \frac{1}{4} z +\frac{3}{4}

Step-by-step explanation:

z^{1}=−3+4i

4i−3=z

4i−3+3=z+3

4i=z+3

\frac{4i}{4} = \frac{z+3}{4}

An architect is sketching a blueprint of a patio for a new fence. On the blueprint, C is the midpoint of segment AD. Point B is
Gre4nikov [31]

Answer:

<u><em>The length of AD is 32 feet</em></u>

Step-by-step explanation:

<u>Proportional distances </u>

When distances are proportions of others, we can express all of them as relative fractions until we reach some known distance and solve for the desired length

Let's call x the length of AD. Given C is the midpoint of AD, then

\displaystyle AC=CD=\frac{x}{2}

Given B is the midpoint of AC, then

\displaystyle AB=BC=\frac{AC}{2}=\frac{x}{4}

If we know BC=8 feet

\displaystyle \frac{x}{4}=8\ feet

\displaystyle x=32\ feet

The length of AD is 32 feet

Find the geometric mean between each pair of numbers. sq root 49 and sq root841
vodomira [7]

<u>Answer:</u>

The geometric mean between each pair of numbers \bold{\sqrt{49} \text { and } \sqrt{841} \text { is } 14.24}

<u>Solution:</u>

The Geometric mean between two numbers a and b is given as  Geometric mean = \bold{\sqrt{ab}}   --- eqn 1

The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root for the numbers.

From question, given that two numbers are \sqrt{49} and \sqrt{841}

Hence we can say “a” = \sqrt{49} =7  

Similarly “b” = \sqrt{841} = 29  

We have to find the geometric mean between “7” and “29”

By using equation 1,  

Geometric mean between 7 and 29 = \sqrt{7 \times 29} = \sqrt{203} = 14.24

Hence the geometric mean between \sqrt{49} \text { and } \sqrt{841} \text { is } 14.24
