An isosceles triangle’s altitude will bisect its base. Which expression could be used to find the area of the isosceles triangle

omeli [17]

Answer:

$\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}$

Step-by-step explanation:

The length of the base is the distance between the points 4+2i and 10+4i, so

$\text{Base}=|10+4i-(4+2i)|=|10+4i-4-2i|=|6+2i|=\sqrt{6^2+2^2}=\\ \\=\sqrt{36+4}=\sqrt{40}$

The middle point of the base is placed at point

$\dfrac{4+2i+10+4i}{2}=\dfrac{6i+14}{2}=7+3i$

The length of the height is the distance between the points 5+9i and 7+3i

$\text{Height}=|5+9i-(7+3i)|=|5+9i-7-3i|=|-2+6i|=\sqrt{(-2)^2+6^2}=\\ \\=\sqrt{4+36}=\sqrt{40}$

So, the area of the triangle is

$A=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}=\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}$

zhenek [66]

14554345555556675566669878 is your answer.

All you have to do when adding 1 is add the number at the very end of the number +1.

It's quite easy.

Glad I could help, and good luck!

True or false: for any 2 nonzero integers, the product and quotient have the same sign.

scoray [572]

Yes, it is true.
________________
For example,

take two integers 12 and 4

12 × 4 = 48 : product is positive

12 ÷ 4 = 3: quotient is positive
____________________

If you take -12 and 4

-12 × 4 = -48 : product is negative

-12 ÷ 4 = -3: quotient is negative

Keith’s dog weighs 90 pounds and a healthy dog’s weight is less than 75 pounds. If Keith’s dog looses 1.25 pounds per week, how

vivado [14]

Answer:

12 weeks.

Step-by-step explanation:

Keiths dog will need to lose 15 pounds to get down to 75 pounds. If he loses 1.25 pounds per week, it will take 12 weeks to get down to 75 pounds. To figure this out, you would use the equation:

90 - 75 = 15

15 / 1.25 = 12

That is how you would get 12 weeks.
