Given:
The triangle PQR on a coordinate plane.
To find:
The image of point Q after a rotation of 90° counterclockwise about the origin.
Solution:
From the given graph, it is clear that the coordinates of point Q are (5,0).
If the figure is rotated 90° counterclockwise about the origin, then the rule of rotation is defined as
[tex](x,y)\to (-y,x)[/tex]
Using this rule, we get
[tex]Q(5,0)\to Q'(-(0),5)[/tex]
[tex]Q(5,0)\to Q'(0,5)[/tex]
So, the image of point Q is (0,5).
Therefore, the correct option is (a).

A new car is purchased for $32,500. The car depreciates every year ata
rate of 14%. Write an exponential function that represents that situation
Answers
Answer:
[tex]y=32500(0.86)^{x}[/tex]
Step-by-step explanation:
General exponentially depreciating function is given as
[tex]y= a(1-b)^{x}[/tex]------------(1)
Where a is initial value, b is percent depreciation/unit time and x is time
Here
[tex]a=32,500 \ \ \ b=0.14 \ \ \ and \ \ x \ is \ time \ in \ years[/tex]
Substituting above values in equation (1)
[tex]y=32500(0.86)^{x}[/tex]
At x=0
[tex]y=32500(0.86)^{0}\\y=32500[/tex]
At x=1
[tex]y=32500(0.86)^{1} \\y=27950[/tex]

Answers
Answer:
x = 18
m<A = 166°
Step-by-step explanation:
The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.
7x + 40 = 3x + 112
4x = 72
x = 18
m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
7x+40 = 3x+112
x=18
7(18)+40
<A = 166
Todos los días por la mañana Alfonso maneja a una velocidad de 80 km/hr para llegar a su trabajo a tiempo realizando un tiempo de 42min de regreso por la tarde disminuye su velocidad a 65km/hr ¿cuanto tiempo tarda para llegar a casa
Answers
Distancia = velocidad x tiempo
= 80 km/hr x 42 minutos
= 56 km
Tiempo = distancia / velocidad
= 56 km / 65 km/hr
= 51,6923 minutos
= 51,6923 min
= 0 horas, 51 minutos, 42 segundos
Espero que esto te ayude.
Usando proporciones, tiene-se que tardará 52 minutos para llegar a casa.
-----------------------------
Esta pregunta se resuelve por proporciones, usando una regla de tres. Considerando que la velocidad y el tiempo son inversamente proporcionales, a medida que uno aumenta y el otro disminuye, se aplica una regla inversa de tres, en la que la multiplicación está en la línea en lugar de cruzada.-----------------------------
80km/hr tiene un tiempo de 42 min. Qual el tiempo a una velocidad de 65 km/hr?80 km/hr - 42 min
65 km/hr - x min
Multiplicando las líneas:
[tex]65x = 80 \times 42[/tex]
[tex]x = \frac{80 \times 42}{65}[/tex]
[tex]x = 52[/tex]
Tardará 52 minutos para llegar a casa.

Step-by-step explanation:
Okay, so this is a fairly challenging problem.
Parallel lines have the same slop, but different y-intercepts.
The new equation is y = 4/3 x + b
Now substitute x and y for the point's coordinates...
-4 = 4/3 (3) + b
(solve for b)
-4 = 12/3 + b
-4 = 4 + b
b = -8
The final equation is:
y = 4/3 x - 8
In point-slope form, this is B

Answers
Answer:
x=8
Step-by-step explanation:
Angle S and R are remote interior angles which means that they would add up to equal angle RQK.
78+5x-1=15x-3
Combine like terms
77+5x=15x-3
Add 3 on both sides
80+5x=15x
Subtract 5x on both sides
80=10x
Divide 10 on both sides
x=8
Details: Cargo ship can carry 21,600 tons Cars weigh 3.6 tons each Trucks weigh 7.5 tons each y = number of cars x= number of trucks Your equation was 3.6y + 7.5x = 21600 Find the number of trucks that can be shipped if there are no cars.
Answers
Given:
The equation is
[tex]3.6y+7.5x=21600[/tex]
where, y is the number of cars and x is the number of trucks shipped.
To find:
The number of trucks that can be shipped if there are no cars.
Solution:
We have,
[tex]3.6y+7.5x=21600[/tex]
If there are no cars in the cargo ship, then y = 0 because y is the number of cars.
Putting y=0 in the given equation, we get
[tex]3.6(0)+7.5x=21600[/tex]
[tex]0+7.5x=21600[/tex]
[tex]7.5x=21600[/tex]
Divide both sides by 7.5.
[tex]x=\dfrac{21600}{7.5}[/tex]
[tex]x=2880[/tex]
x is the number of trucks shipped.
Therefore, the number of trucks that can be shipped if there are no cars is 2880.

I need the answer fast please!!
Answers
Answer:
I believe the answer is x=7
Step-by-step explanation:
3x and 4x-1 are corresponding sides and so are 14 and 18.
You cross multiply with the smaller triangle lengths at the top.
3x/(4x-1)= 14/18
Cross multiply to get
18(3x)= 14(4x-1)
54x=56x-14
Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)
you get 14=2x and divide 14 by 2 to get x=7

Yes Or No
Answers
Answer:
Yes.
Step-by-step explanation:
First, draw a vertical line. Then check the interception between the graph and a vertical line.
If the line intercepts the graph only one point, then it is a function. Otherwise, it is not. That includes two or more.
