Answer:
B=42°C=98°c=10.7 unitsStep-by-step explanation:
Given
Angle A = Ф = 40°a=8b=7We know that trigonometric ratio as
sin Ф = opposite/hypotenusecos Ф = adjacent/hypotenusetan Ф = opposite/adjacentas
sin A = sin 40 = opposite/hypotenuse
From the diagram, it is clear that the opposite of angle A is a=8 and the hypotenuse is 'c'.
also the angle
sin A = sin 40 = opposite/hypotenuse = a/c = 8/c
sin 40 = 8/c
c = 8/sin 40
c = 8/0.745
c = 10.7
so the value of c will be: 10.7 units
so
tan B = opposite/adjacent
= b/a
= 0.9
[tex]B=\tan ^{-1}\left(0.9\right)[/tex]
[tex]=42^{\circ \:}[/tex]
Therefore, the value of B = [tex]42^{\circ \:}[/tex]
As the sum of the angles of triangle ABC is 180.
i.e.
A+B+C = 180
(40)° + (42)° + C = 180°
C = 180° - 40° - 42°
= 98°
Therefore, the value of C = 98°
Hence,
B=42°C=98°c=10.7 unitswhat is the domain of this scatter plot?

Answer:
The points that lie in the solution set of following system of inequalities are:
Option A (1,-5) and Option C (5,1)
Step-by-step explanation:
We need to find the points that lie in the solution set to the following system of inequalities
[tex]y<-3x+3\\y<x+2[/tex]
We will check each option to identify if they satisfy the given set of inequalities or net.
Option A (1,-5)
We have x=1, y=-5
Putting values and checking
[tex]\\y<-3x+3\\-5<-3(1)+3\\-5<0 \ (true)\\y<x+2\\-5<1+2\\-5<3 \ (true)[/tex]
So, Option A is correct as both values satisfy the given set of equations
Option B (1,5)
We have x=1, y=5
Putting values and checking
[tex]y<-3x+3\\5<-3(1)+3\\5<0 \ (false)\\y<x+2\\5<1+2\\5<3 \ (false)[/tex]
So, Option B is not correct as both values doesn't satisfy the given set of equations
Option C (5,1)
We have x=5, y=1
Putting values and checking
[tex]y<-3x+3\\1<-3(5)+3\\1<-15+3\\1<12 \ (true)\\y<x+2\\1<5+2\\1<7 \ (true)[/tex]
So, Option C is correct as both values satisfy the given set of equations
Option D (-1,5)
We have x=-1, y=5
putting values and checking
[tex]y<-3x+3\\5<-3(-1)+2\\5<3+2\\5<5 \ (false)\\y<x+2\\5<-1+2\\5<-1 \ (false)[/tex]
So, Option D is not correct as both values doesn't satisfy the given set of equations

A = {put, the, cake, in, basket}
B = {is, the, cake, in, basket}
C = {no, the, cake, in, basket}
D = { }
Step-by-step explanation:
A = (A -B) ∪ (A∩B) ∪ (A∩C}
A = {put} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}
A = {put, the, cake, in, basket}

B = (B -A) ∪ (B -C) ∪ (B∩A) ∪ (B∩C)
B = {is} ∪ {is} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}
B = {is, the, cake, in, basket}

Use the provided information to write the standard form equation of the parabola.
Opens up or down, and passes through (8,0), (13,-5), and (12,0)
Answer:
f(x) = -x² + 20x - 96Step-by-step explanation:
Parabola f(x) = ax² + bx + c passing through points (8,0) and (12,0) means that 8 and 12 are its root and (x-8) and (x-12) are its factors
So we get:
f(x) = a(x - 8)(x - 12)
The parabola passes through point (13, -5) that means if x=13 then f(x)=-5
So:
-5 = a(13 - 8)(13 - 12)
-5 = a(5)(1)
-5 = 5a
a = -1 {<0 so parabola opens down}
Therefore:
f(x) = -(x - 8)(x - 12)
And expanding:
f(x) = -(x² - 12x - 8x + 96)
So the standard form equation of the parabola:
f(x) = -x² + 20x - 96

It is estimated that there are 828 motor vehicles in the US it is estimated that there are 828 Motor vehicles in the US for every 1,000 people. If the number of
motor vehicles in the US is 260 million, then what is its population to the nearest million?
A) 215 million B) 314 million C) 315 million D) 475 million PLZ HELP I NEED THIS QUESTION ANSWERED QUICKLY!!!!
Answer:
314 million
Step-by-step explanation:
Given that :
Number of motor vehicle in the U.S for every 1000 people = 828
If the number of motor vehicle in the United States = 260 million
Then,
Let x = number of people Given number of vehicles = 260,000,000
1000 people = 828 vehicles
x = 260,000,000
828x = (260,000,000 * 1000)
828x = 260,000,000,000
x = 314009661. 835
x = 314 million (approx)
(-8,7), m=5
Y-7=5(x+8)
Answer:
The line of the equation is:
[tex]y-7=5\left(x+8\right)[/tex]
Step-by-step explanation:
Given
m=5point (-8, 7)As the point-slope form is given by
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values m=5 and the point (-8, 7)
[tex]y-7=5\left(x-\left(-8\right)\right)[/tex]
[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]
[tex]y-7=5\left(x+8\right)[/tex]
Therefore, the line of the equation is:
[tex]y-7=5\left(x+8\right)[/tex]

Um técnico em eletricidade recebeu um molho que continha 12 chaves não identificadas pra abrir a porta de um quarto de hotel e efetuar os reparos necessários na rede elétrica.qual a probabilidade de ele acertar na primeira tentativa
Answer:
Step-by-step explanation:
Dado que:
Um técnico em eletricidade recebeu um pacote que continha 12 chaves não identificadas, a probabilidade de que ele acertasse na primeira vez será:
= número de ensaios / número total de ensaios disponíveis
O técnico eletricista tem apenas uma tentativa
uma vez que existem 12 chaves não identificadas, o número total de testes disponíveis 12
∴
= 1/12
= 0.0833
= 0.0833 × 100

Greta uses 2oz of pasta to make 2/3 of a serving of pasta.How many oz of pasta are there per serving
Answer:
3oz of pasta per serving
Step-by-step explanation:
Given parameters:
Number of oz of pastas used = 2oz
Quantity of serving = [tex]\frac{2}{3}[/tex]
Unknown:
Number of oz of pasta per serving = ?
Solution:
To solve this rate problem use;
Number of oz of pasta per serving = [tex]\frac{number of oz of pasta}{number of serving}[/tex]
Number of oz of pasta per serving = [tex]\frac{2}{\frac{2}{3} }[/tex] = 2 x [tex]\frac{3}{2}[/tex] = 3oz of pasta per serving
