Triangle P N M is shown. The length of P N is 7, the length of N M is 8, and the length of M P is 11.
Law of cosines: a2 = b2 + c2 – 2bccos(A)
Which equation correctly applies the law of cosines to solve for an unknown angle measure?
72 = 82 + 112 – 2(8)(11)cos(N)
82 = 72 + 112 – 2(7)(11)cos(M)
72 = 82 + 112 – 2(8)(11)cos(P)
82 = 72 + 112 – 2(7)(11)cos(P)
Answer:
8^2 = 7^2 + 11^2 – 2(7)(11)cos(P)

The equation correctly applies the law of cosines to solve for an unknown angle measure is equation D.
What is a Triangle?A triangle is a polygon with three sides, three vertices, and three angles.
The length of P N is 7,
The length of N M is 8, and
The length of M P is 11.
The law of cosines is used to determine the missing sides and angles if two sides and an angle are given or three sides are given respectively.
The equation that correctly applies should have the two sides and the cosine of the included angle.
The correct equation is 8² = 7² + 11² – 2(7)(11)cos(P)

An appliance is for sale at either (a) P15,999 cash or (b) on terms, P1,499 each month for the next 12 months. Money is 9% compounded monthly. Which is lower, the cash price or the present value of the installment terms? Explain.
Answer:
Cash price
Step-by-step explanation:
The computation is shown below:
The Interest rate per month (r) = (9% ÷ 12) = 0.75%
Now Present value of the monthly payment is
= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}
= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}
= 18,748.89
And the cash price is 15,999
So, the cash price would be lower
The cash price would be lower. A further explanation is below.
According to the question,
Interest rate per month,
[tex]r = \frac{9 \ percent}{12}[/tex]
[tex]= 0.75[/tex] (%)
hence,
The Present value of the monthly payment will be:
= [tex]PMT\times \frac{{(1 + Interest \ rate)^{number \ of \ years} - 1}}{Interest \ rate}[/tex]
= [tex]1499\times \frac{[(1 + 0.75 \ percent)^{12} - 1] }{0.75 \ percent}[/tex]
= [tex]18748.89[/tex]
As we can see that the cash price is 15,999. Thus the above answer is right.

Step-by-step explanation:
find 'x' by adding all expressions and setting them equal to 360°
9x+1 + tx+12 + 10x-37 = 360

A circle is subdivided by a central angle of 90 degrees. The length of the subtended arc is 25 mm. What is the radius of the circle?
A:
[tex] \frac{50}{\pi} mm[/tex]
B:
[tex] \frac{\pi}{50} mm[/tex]
C:
[tex] \frac{25\pi}{2} mm[/tex]
D:
[tex]25mm[/tex]
Answer:
[tex](\text{A})\:\frac{50}{\pi}\:\text{mm}[/tex]
Step-by-step explanation:
This the arc is 90 degrees and there are 360 degrees in a circle, it makes up [tex]\frac{90}{360}=\frac{1}{4}[/tex] of the circle. Therefore, its length will be [tex]\frac{1}{4}[/tex] of the circumference. Since its length is 25 mm, the circumference is then [tex]25\cdot 4=100\:\text{mm}[/tex]. The circumference of a circle is given by [tex]2\pi r[/tex], where [tex]r[/tex] is the radius of the circle. Therefore, we can set up the following equation and solve for [tex]r[/tex]:
[tex]2\pi r=100[/tex]
Solving, we get:
[tex]2\pi r=100,\\\\r=\frac{100}{2\pi},\\\\r=\boxed{(\text{A})\:\frac{50}{\pi}\:\text{mm}}[/tex].

Which of the rules given below shows the transformation of f?
OA g(x) = f(x) - 4
O B. g(x) = fx-4)
OC.
g(x) = f(x + 4)
OD. g(x) = f(x) + 4
Answer:
A.) g (x) = f (x) - 2
Step-by-step explanation:
The first thing we are going to do in this case is to take into account the following definition.
Translations are transformations that change the position of the graph of a function.
The general shape of the graph of a function is moved up, down, to the right or to the left.
The translations are considered rigid transformations. Now we will see how these are performed.
Vertical translations:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
Using the definition we conclude that:
g (x) = f (x) - 4
Two exponential functions, fand g, are shown in the figure, where g is a transformation of f, g (x) = f (x) - 4 equation shows transformation of f. The correct option is A.
What is exponential function?A mathematical function of the form [tex]f(x) = a^x[/tex], where an is a positive constant and x is the input variable, is an exponential function.
The characteristic curve of exponential functions rises or falls rapidly depending on whether an is greater or less than 1.
To determine the transformation of f which gives g, we need to examine how f has been transformed to obtain g.
Looking at the graph, we can see that g is a vertical shift of f. Specifically, g is obtained by shifting f downward by 2 units. Therefore, we need a rule that subtracts 2 from f (x) to get g (x).
Out of the given options, the only one that matches this description is:
g (x) = f (x) - 4
Option A subtracts 4 from f (x), which is not what we observe in the graph. Option B uses an incorrect format and is also subtracting 4 from f (x).
Option C adds 4 to x, which would result in a horizontal shift, not a vertical shift.
Therefore, the correct answer is A g (x) = f (x) - 2.

what is 18 rounded to the nearst 1/4
Answer:
18
Step-by-step explanation:
1/4 is close to 0 so 18 rounded to the nearest ones place is just 18
Answer:
20
Step-by-step explanation:
When we round to the nearest ten, we will round up to a number that has a zero in the ones place but we have to look at the number in the ones place before we round to determine the number in the tens place. The rule is if the number in the place before the place we need to round (in this case the ones place would be what we look at to determine the rounded tens place) 1-4 is going to round down, keeping the tens place the same and the ones place goes to zero, and if the ones number place is 5-9 then we round up, bringing the ones to zero and the tens up by one tens place.

Daniel buys 17 raffle tickets.
A total of 280 tickets were sold
What’s the probability that Daniel does not win the prize
Answer:
263 / 280
Step-by-step explanation:
Given that :
Number of tickets bought = required outcome = 17
Total number of raffle = total possible outcomes = 280
Probability = required outcome / Total possible outcomes
P(winning) = 17 / 280
P(not winning) = 1 - 17/ 280
= 263 / 280
