Plz help thx!!!! each box needs to be filled in! with a conjunction of IR.

Write an equation of the circle with center (7,4) and diameter 10

cestrela7 [59]

Circles follow ghe equations
(x-h)^2 + (y-k)^2 =r^2
with center (h,k) and radius r
for this circle it would be
(x-7)^2 + (y-4)^2 = 100

Yo plz help I suck at Pythagoras theoreom >:(

Answer:

Step-by-step explanation:

you didn't put the problem you are stuck on here, but i am willing to help you out in understanding Pythagorean theorem!

pythagorean theorem helps to solve for a side of a right triangle! no matter which two sides you are given in the problem!

the formula for this is

a^2 + b^2 = c^2

to solve for it, you plug in the two sides you have. the most simple is the two sides that are not the hypotenuse. the hypotenuse is the longest side, which is also not connected to another side by a right angle.

you should then plug those numbers into a and b. if you're not too strong with squaring a number, just use a calculator! its super easy to plug into!

lets make a scenario, you have two sides that are 3 and 3 and you are trying to find your hypotenuse!

you would plug them into A and B, if you have different numbers, it doesn't matter which slot they go into :)

so... 3^2 + 3^2 = c^2

when you put 3 to the 2nd power in the calculator, it gives you 9!

so, 9 + 9 = c^2 18 = c^2

you are not done yet :)

you have the number is squared. you must now take the square root of the number!

this is not going to be a whole number, or a pretty one, but it will be correct.

sqrt18 = c

4.242640687119285 is the hypotenuse.

whatever problem you have should say what to round to, lets just say to the nearest hundredth.

4.24 is your hypotenuse.

i really hope i helped you out in anyway possible.

if you have any other questions based on what i just did, or if you need some information that goes a little bit deeper into pythagorean theorem, i would be glad to help you!

stay safe!

Erin invests $7000 in stocks and bonds. The bonds earn 5% annual interest and the stocks earn 8% interest. If she earns $404 in

Marina CMI [18]

Answer:

$\large \boxed{\$5200}$

Step-by-step explanation:

Let b = the amount invested in bonds

Then 7000 -b = the amount invested in stocks

0.05b = interest from bonds

0.08(7000 - b) = interest from stocks

$\begin{array}{rcll}0.05b +0.08(7000 - b) & = & 404 &\\0.05b + 560 - 0.08b&=&404&\text{Distributed the 0.08}\\-0.03b + 560 & = & 404 & \text{Simplified}\\-0.03b & = & -156 & \text{Subtracted 560 from each side}\\\\b & = & \dfrac{-156}{-0.03} & \text{Divided each side by -0.03}\\\\b & = &\mathbf{5200}\\\\\end{array}\\\text{Erin invests $\large \boxed{\mathbf{\$5200}}$ in bonds}$
