7.  Not congruent

8.  Congruent by the HL theorem

HL = hypotenuse leg

==========================================

Explanation for problem 7

The tickmarks on segments MA and AT tell us that these segments are congruent. Another pair of congruent segments would be AE = AE by the reflexive property.

Then angle EMA = angle ETA because of the similar arc markings for those angles.

We have these congruence facts:

But recall that the "side side angle" rule isn't a valid congruence theorem. Search out "SSA ambiguous case" for more information.

We cannot use SAS because the angle is not between the sides mentioned.

Therefore, we don't have enough information to determine if the triangles are congruent or not. We can't say they are congruent, so the only thing we can do is say "not congruent" until more info comes along.

------------

Explanation for problem 8

We use the HL (hypotenuse leg) theorem. It works for right triangles only.

The congruent legs are segment ON = segment ON because of the reflexive property.

The congruent hypotenuses are MN = RO because of the tickmarks.

In short, the triangles are congruent by the HL theorem.

The evaluated speed of P is 54.5 m s¯¹, under the condition that two forces F₁ and F₂ act on a particle P. The force F₁ is given by F₁ = (-i + 2j) N and F₂ acts in the direction of the vector (i + j).

To evaluate the speed of particle P when t = 3 seconds, we can apply the equations of motion formulas to calculate the velocity if the acceleration and initial velocity values are already given.
The formula can be derived :
v = u + at
Here,
v =  final velocity of the particle,
u = initial velocity of the particle,
a = acceleration acting on the particle
t = time taken.
It is known to us that the acceleration of P is (3i + 9j) ms² and at time t = 0, the velocity of P is (31 -22j) m s¯¹. We can evaluate the initial velocity u by taking the magnitude of (31 -22j) that is
√(31² + (-22)²)
= 39.051 m s¯¹.
Now we can staging all values into the formula
v = u + at
v = 39.051 + (3i + 9j) × 3
v = 39.051 + (9i + 27j)
v = (39.051 + 9)i + (27)j
v = 48.051i + 27j
Then, when t = 3 seconds, the speed of particle P is √(48.051² + 27²)
= 54.5 m s¯¹.

The general form of the function is:

y = A sin(Bx - C) + D

To determine the specific values of A, B, C, and D that satisfy the given conditions, we can use the following steps:

Period: The period of a sinusoidal function is given by 2π/B, where B is the coefficient of x in the argument of the sine function. In this case, the period is 8, so we have:

2π/B = 8

Solving for B, we get:

B = π/4

Phase shift: The phase shift of a sinusoidal function is given by C/B, where C is the constant inside the argument of the sine function. In this case, the phase shift is -2, so we have:

C/B = -2

Substituting B from step 1, we get:

C/(π/4) = -2

Solving for C, we get:

C = -π/2

Amplitude and vertical shift: The range of the function is given as -12 ≤ y ≤ -4. The amplitude of a sinusoidal function is half the distance between its maximum and minimum values. In this case, the amplitude is:

(amplitude) = (maximum - minimum)/2 = (-4 - (-12))/2 = 4

The vertical shift of the function is given by the constant term D. Since the minimum value of the function is -12, we have:

D + (amplitude) = -12

Substituting the value of the amplitude from above, we get:

D + 4 = -12

Solving for D, we get:

D = -16

Therefore, the function of the form y = A sin(Bx - C) + D that has period 8, phase shift -2, and the range -12 ≤ y ≤ -4 is:

y = 4 sin(π/4 x + π/2) - 16

Answer: The total sum of all monthly payments required to pay off this loan is $410,932.

To calculate this, we need to first find the amount of the loan that is not covered by the deposit. The deposit is 20% of $300,000, or $60,000, so the remaining amount of the loan is $300,000 - $60,000 = $240,000.

Next, we need to calculate the monthly payment on the loan. We can use the formula for a fixed-payment loan to do this:

Payment = (Loan amount x Monthly interest rate) / (1 - (1 + Monthly interest rate)^(-Number of months))

The monthly interest rate is the annual interest rate divided by 12, or 0.0394 / 12 = 0.003283.

The number of months is the number of years times 12, or 30 x 12 = 360.

Plugging these values into the formula gives:

Payment = ($247,249 x 0.003283) / (1 - (1 + 0.003283)^(-360)) = $1,151.80

Finally, we can find the total sum of all monthly payments by multiplying the monthly payment by the number of months:

Total payments = $1,151.80 x 360 = $410,932 (rounded to the nearest whole number).

The hypotenuse of each of these right triangles can be found using Pythagorean theorem....the hypotenuse is also the DIAMETER of the circle

   diamter * pi = circumference

First one:

  Hypot^2 = 13^2 + 13^2

    hypot ^2 = 338

     hypot = diameter = sqrt (338)

   circumference = diamter * pi  =  sqrt 338 pi   ft   ( or 13 sqrt(2) pi   ft )  

The second one is the same with slightly different numbers...you try it ...

Answer:[tex]\sqrt{338}\pi[/tex], [tex]25\pi[/tex]

Step-by-step explanation:

I will start with the second one, since it will be easier. Because this is a right triangle, you can use the given side lengths of the triangle to find the hypotenuse, which is also equal to the diameter of the triangle. Since the pythagorean theorem states that a^2(the shorter leg, squared) + b^2 (the longer leg, squared) = c^2 (the hypotenuse, squared) we can turn it into an equation like this:

[tex]7^{2\ }+\ 24^{2}\ =\ c^{2}[/tex]

(lets use x in place of c in the next few equations, for algebraic simplicity)

Simplify

[tex]49+\ 576\ =x^{2}[/tex]

[tex]625=x^{2}[/tex]

Get the square roots

[tex]\sqrt{625}=\sqrt{x^{2}}[/tex]

[tex]x=25[/tex]

Since x is equal to the hypotenuse, we know that the hypotenuse is also 25. This means the diameter of the second circle is 25, and we can now find the circumference. The EXACT circumference of the second circle is 25π, but a simplified version can be created by calculating it as if it were an equation. This comes out to around 78.5398163397, which would trail for infinity. which is why to get an exact measurement of the diameter, the most simplified exact version is displayed by multiplying the diameter by the pi symbol, because it is impossible to fit an infinite number in a finite space.

Now for the first circle, which I am now realising is no more difficult than the last one. We can do the same thing in this case, using pythagorean theorem, because there are two dash lines marking two of the lines on the circle to be equal to one another, we know that the two marked lines are equal to 13, despite not appearing to be.

We can use the same equation as we did before, but slightly modified.

[tex]13^{2}+13^{2}=x^{2}[/tex]

Simplify:

[tex]169+169=x^{2}[/tex]

[tex]338=x^{2}[/tex]

Now we can take the square roots of both sides of the equation.

[tex]\sqrt{338}=\sqrt{x^{2}}[/tex]

This is where we come to a bit of a pause. Because the square root of 338 is an irrational constant number, we have to use the unsimplified square root in our answer for the circumference, otherwise, our answer would not be exact.

The diameter of our circle is [tex]\sqrt{338}[/tex], which means that we can use an equation like this to find the circumference:

[tex]\sqrt{338}\pi[/tex]

But since we cannot simplify this any further without it not being exact, we must leave it as is.

0.20 / (1 - 0.20) = 0.20 / 0.80

- Simplify the fraction:

0.20 / 0.80 = 1 / 4

The odds in favor of an event with a probability of 0.20 is a ratio of 1 to 4.

The question is about calculating the odds in favor of an event with a probability of 0.20. The odds in favor of an event is defined as the ratio of the probability that the event will happen to the probability that it will not happen.

In this case, the probability of the event is 0.20, therefore the probability that it will not happen is 1 - 0.20 = 0.80. So, the odds in favor of the event are 0.20 to 0.80 or it can be simplified to 1 to 4.
