y=2000(1+.09^2)^1/2

y=2000(1.09^2)1/2

y=2000(1.1881)^1/2

y=2000(1.09)

y=$2180

In a right triangle ABC, CD is an altitude, such that AD=BC. Find AC, if AB=3 cm, and CD=√2 cm.

Zielflug [23.3K]

Given that triangle ABC is right angle triangle. CD is altitude such that AD=BC

ABC is a right angle triangle so apply Pythogorean theorem

$AC^{2} + BC^{2} = AB^{2}$

$AC^{2} + AD^{2} = AB^{2}$ (Given that AD = BC)

$AC^{2} + AD^{2} = 3^{2}$ (Given that AB=3)

$AC^{2} + AD^{2} = 9$ ...(i)

ADC is a right angle triangle so apply Pythogorean theorem

$AD^{2} + CD^{2} = AC^{2}$

$AD^{2}+(\sqrt{2})^2= AC^{2}$

$AD^{2}+2= AC^{2}$

$AD^{2}=AC^{2} -2$ ...(ii)

Plug value (ii) into (i)

$AC^{2} + AC^{2}-2 = 9$

$2AC^{2} -2=9$

$2AC^{2} =11$

$AC^{2} =\frac{11}{2}$

$AC=\sqrt{\frac{11}{2} }$

Hence final answer is $AC=\sqrt{\frac{11}{2} }$

in year 4 the store sold 112% of the total number of scooters sold during the previous three years combined determine the number

Margarita [4]

Answer:

2, 240

Step-by-step explanation:

In the table, the values should be

Year 1 725

Year 2 579

Year 3 696

Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.

$\frac{112}{100} =\frac{x}{2000}$

We solve through cross multiplication of numerator and denominator of the opposite fraction.

$112(2000)=100(x)\\224000=100x\\2,240=x$

How would you estimate it?

likoan [24]

I would just do for the first one 7/16 - 3/16 = 4/16 which is also 1/4 I'm not sure ho2 you estimate it

Solve the following system of linear equation by graphing. <br>4x + 2y = -2 <br>2x – 3y = 9

Viefleur [7K]

If you can graph in slope intercept, your new equations would be: y= -2x-1 and y= 2/3x-3.
Just graph those now since it should be easier.
