What is the value of Z?

sukhopar [10]

Answer:

Step-by-step explanation:

Both x and y are inscribed angles. The value of an inscribed angle is half the measure of its intercepted arc. This means that x has a value of 33°, and y has a value of 48°. That means that, according to the triangle angle sum theorem, the third angle has to equal 180 - 33 - 48 = 99°.

This angle is vertical with angle z, so angle z also equals 99°

Why do test makers refer to the first term in a sequence as a sub zero sometimes as opposed to a sub 1?

Kaylis [27]

The first term in a sequence is sometimes referred to as $a_0$ as opposed to $a_1$ because $a_0$ represents the initial value

<h3>How to explain the sequence statement?</h3>

The question refers to the difference between the terms

$a_o$ and $a_1$

The terms in a sequence are represented by a subscript number.

Take for instance a₂ or T₂ represents the second term.

However, when the first term is represented by a₀ instead of a₁.

It means that the sequence has an initial value, other than the first term.

Even though the words "first" and "initial" are synonyms, they do not entirely represent the same thing.

Take for instance, a₀ can be used instead of a₁ in the following scenario

<em>The population of a country is 1000 in 1996 and The country experiences an increment of 250 people every year after 1996.</em>

<em />

The above means that:

a₀ = 1000 --- the initial year

a₁ = 1000 + 250 = 1250 ---- the first year after 1996 (i.e. 1997)

1. Christopher wants to invest $6200 in a retirement fund that guarantees a return of 9% annually using continously compounded i

frosja888 [35]

1. Continuously compounded formula is given by:
A=Pe^rt
Thus given:
P=$6200, r=0.09, t=20 years:
A=6200e^(0.09*20)
A=37,507.81

Answer: c] $37507.81

2. Compound interest formula is given by:
A=p(1+r/100n)^(nt)
where: n=number of terms, p=principle, t=time, r=rate
Plugging the values in the formula we get:
A=2600(1+4.25/4*100)^(4*5)
simplifying this we get:
A=$3211.99

Answer: b)$3211.99

3. Using the formula from (2) we have:
A=P(1+r/100n)^nt
plugging in the values we get:
A=2600(1+4.25/400)^(50*4)
Simplifying the above we get:
A=$21526.87

Answer:
A] $21,526.87

4. The price of stock when the bond is worth $68.74 will be:
let the bond price be B and Stock price be S
thus
S=k/B
where
k is the constant of proportionality
thus
k=SB
hence
when S=$156 and B=$23
then
K=156*23
K=3588
thus
S=3588/B
hence
the value of S when B=$68.74
thus
S=3588/68.74
B=52.19668~52.20

Answer: d] $52.20

5. Continuously compounded annuity is given by:

FV =CF×[(e^rt-1)/(e^r-1)]
plugging in the values we get:
FV=500×[(e^(6*0.08)-1)/(e^0.06-1)]
simplifying this we get:
FV=$3698.50

Florences monthly take home pay is $5000 and her monthly rent is $900. If both her monthly and take home lay and her rent increa

max2010maxim [7]

If 5000 gets increased by 200, then you end up with 5200.

if 900 gets increased by 200, then it'd be 1100.

so in short, if we take 5200 to be the 100%, what is 1100 in percentage from it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
5200&100\\
1100&p
\end{array}\implies \cfrac{5200}{1100}=\cfrac{100}{p}\implies p=\cfrac{1100\cdot 100}{5200}$
