Answer:

These kind of problems are super difficult Anna, don't feel bad for not getting this. there is a bunch of "implied" ideas here... i'll go over them below, maybe it will seem a bit easier. if not, ask some more questions in the comments of this problem , I'll see the comments and answer your question

Step-by-step explanation:

the 1st implied idea is that there is 360 ° in a circle

next you have to know, that the angle x is also matched on the interior of the circle where the line of the angle x, first touches the circle. if that is confusing , don't worry i'll make a rough drawing to show you.

so we can know that the arc from the point where the angle x makes the tanget.. or just touches the circle to where it's other leg crosses the circle the 1st time, that's angle is equal to the arc that is left over from the total circle. see this is very "implied" nobody said.. by the way... it's 360 ° minus the other arcs.. well.. I just did.. but you had to come up with that on your own, before I said that.

x = left over arc

360 = 200 + 40 + x

120 = x

Answer:

$\boxed{\sf{4}}}$

Step-by-step explanation:

Use a slope form.

Slope:

$\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }$

y₂ = (17)

y₁ = (1)

x₂ = (2)

x₁ = (-2)

Then, rewrite the problem.

Solve.

$\sf{\dfrac{17-1}{2-(-2)}=\dfrac{16}{4}=\dfrac{16\div4}{4\div4}=\dfrac{4}{1}=\boxed{\sf{4} }$

Therefore, the slope is 4, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

1.) 9.2

2.)

625

633

the dealer

8.81

Step-by-step explanation:

I'm gonna assume that cm= compounded monthly

1.)

effective rate: .153/12= .01275

x= payments

$2590.67=300*\frac{1-(1+.01275)^{-x}}{.01275}\\.110103476=1-1.01275^{-x}\\.889896525=1.01275^{-x}\\\log_{1.01275}.889896525=-x\\x=9.207$

2.)

If there is no interest rate attached to financing through the deal the payment is just

37500/60 = 625

The monthly payment from the bank has a present value of 37500-3000=34500

and the effective rate is .039/12= .00325

$34500=x\frac{1-(1.00325)^{-60}}{.00325}\\34500=54.43234738x\\x=633.81$

Finally, the amount we save is just the difference

633.81-625=8.81

Kate has a kite with the dimensions shown below. What is the value of X?

sergij07 [2.7K]

Hey there! :D

We will use the properties of similar triangles to figure this out.

We will use two triangles inside the kite, with sides with the value of "x".

Smaller triangle:

Smaller side= 11

Bottom side= x

Bigger triangle:

Smaller side= x

Bottom side= 25

$\frac{11}{x} = \frac{x}{25}$

Cross multiply.

25*11= 275

x*x= $x^{2}$

Find the square root.

√275= 16.583....

Or 5√11.

I hope this helps!
