Find the radius of a circle with an area of 16x^2+24x+9

Diano4ka-milaya [45]

Area of circle =π *r^2
so π*r^2 = π(16x^2 + 24x + 9)
r^2 = 16x^2 + 24x + 9
= (4x +3)(4x+3)
= (4x +3)^2
Take square roots of both sides
r = 4x +3

An airplane leaves an airport and flies due west 150 miles and then 170 miles in the direction S 49.17°W. How far is the plane f

Sphinxa [80]

Answer:

Distance between plane and airport is 134.4 miles.

Step-by-step explanation:

Given : An airplane leaves an airport and flies due west 150 miles and then 170 miles in the direction S 49.17°W.

To find : How far is the plane from the airport.

Solution : Distance from airport to west is 150 miles and then 170 miles in the direction south and angle form is S 49.17° W

Refer the attached picture for clearance.

Applying law of cosines

$c^2=a^2+b^2-2ab Cos(C)$

$c=\sqrt{a^2+b^2-2ab Cos(C)}$

where a= 150 miles

b=170 miles

C= 49.17° angle in degree

c = distance between plane from the airport

Put values in the formula,

$c=\sqrt{a^2+b^2-2ab Cos(C)}$

$c=\sqrt{150^2+170^2-2(150)(170) Cos(49.17^{\circ})}$

$c=\sqrt{22500+28900-51000(0.653)}$

$c=\sqrt{51400-33303}$

$c=\sqrt{18057}$

$c=134.37$

Therefore, Distance between plane and airport is 134.4 miles.

A town has a population of 2000 and grows at 4% every year what will be the population after 15 years to the nearest whole numbe

fomenos

To begin lets say year one the population is 2,000

assume this in percent we can say that 2,000=100%

at the end of this year the population will have grown by 4% meaning that

100%+4% will be the new population =104%

but we know that 100%=2,000 so what about 104%=X?

so (104*2000)/100=2,080

So year 1 the population will have grown by 80 people amounting to 2080 people.

Now do it manually year by year until we reach the 15th year. i will help you up to year 3

2nd year= (2080*104)/100=2163.2

3rd year= (2163*104)/100=2249.728

Irina-Kira [14]

Answer:

You didn't tell us much on what to do, so I just guessed you wanted it simplified. If you want a different answer, please do so tell me and I'll edit my answer to fit.

Simplified: 10 $x^{2}$ + $\frac{1}{3x^{3} }$ - 9
