Answer:
I would assume that s is also 5 because its an isosceles triangle. This leaves the hypotenuse side, which would be 7.07. To find a missing side when you have two sides, you can use the Pythagorean theorem, which is . The longest side will always represent c, so when you plug in a and b squared, you will get 50 in total. To get c by itself, you just need to square root it. I hope that made sense!
I’m not sure if this is right cuz I googled it lol but google is telling me
1/4 & 2/9 are perfect squares and the rest aren’t
To calculate the amount that Vince should pay back, we can use the formula of
A = P + PRT
where A is amount (unknown), P is principal ($900), R is rate of interest (1.5%).
Which in this case, Vince did follow the correct formula, but what he did wrong, it that he incorrectly changed the rate to a decimal. Instead, 1.5% should be 0.015 in decimal form.
So, the correct formula should be
A = 900 + 900(0.015x2)
A = 900 + 27
A = 927
So, the correct amount Vince should pay is $927.
Preimage and image are terms that are used when a figure transitions. The preimage is before the figure goes through transition and the image is afterwards
a = 4, b = -21, c = -18
to keep from getting "mixed up", evaluate the discriminant first ...
b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729
sqrt(729) = 27
x = (21 +/- 27)/8
x = -3/4, x = 6
since the discriminant is a perfect square, the original quadratic will factor ...
4x<sup>2</sup> - 21x - 18 = 0
(4x + 3)(x - 6) = 0
x = -3/4, x = 6
