Answer:

A) P = 240

B) P + Po = 1040

C) P = 270.58

D) P+Po = 1070.58

E) Option B (compound interest) is better, as it generates more interest for the same inicial value, rate of interest and time

Step-by-step explanation:

The formula for simple interest is:

P = Po*r*t

Where P is the interest earned, Po is the inicial value, r is the rate of interest and t is the time.

The formula for compound interest is:

P+Po = Po*(1+r)^t

So we have that:

A) P = 800*0.06*5 = 240

B) P + Po = 800 + 240 = 1040

C) P+Po = 800*(1+0.06)^5 = 1070.58 -> P = 1070.58 - 800 = 270.58

D) P+Po = 1070.58

E) Option B (compound interest) is better, as it generates more interest for the same inicial value, rate of interest and time

A circle with radius \pink{6}6start color #ff00af, 6, end color #ff00af has a sector with a central angle of \purple{48^\circ}48

alexandr1967 [171]

Answer:

Therefore,

The area of the sector is 15.09 unit².

Step-by-step explanation:

Given:

Circle with,

radius = r = 6 unit

central angle = θ = 48°

pi = 3.143

To Find:

Area of sector = ?

Solution:

If 'θ' is in degree the area of sector is given as

$\textrm{Area of Sector}=\dfrac{\theta}{360}\times \pi r^{2}$

Substituting the values we get

$\textrm{Area of Sector}=\dfrac{48}{360}\times 3.143\times 6^{2}$

$\textrm{Area of Sector}=15.0864=15.09\ unit^{2}$ rounded to nearest hundredth

Therefore,

The area of the sector is 15.09 unit².

Please help me on this

Gre4nikov [31]

Answer: option a.

Step-by-step explanation:

Given the expression $\sqrt{8^{17}}$ , you need to remember:

The Product of powers property:

$a^m*a^n=a^{(m+n)}$

The Power of a power property:

$(a^m)^n=a^{mn}$

And:

$\sqrt[n]{a^n}=a$

Therefore, as the index of the radical is 2, you can rewrite $8^{17}$ as:

$8^{17}=8^{16}*8$

Rewrite this and simplify. Then:

$=\sqrt{8^{17}}$

$=\sqrt{8^{16}*8}=\sqrt{8^{16}}\sqrt{8}=\sqrt{(8^{8})^2}\sqrt{8}=8^8\sqrt{8}$

This matches with the option a.

Ainat [17]

10^5=100,000
100,000*3.6
360,000
360,000/2400

I believe it’s 150 bolts per minute
