Answer:

The answer is below

Step-by-step explanation:

La distancia entre dos puntos A(x₁, y₁) y B(x₂, y₂) en el plano cartesiano se da como:

AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

El paralelogramo que se muestra en el diagrama tiene vértices en P (3, 6), Q (7, 6), R (9, 2) y S (1, 2)

a) La distancia entre Q y R viene dada por:

QR=\sqrt{(9-7)^2+(2-6)^2} =\sqrt{20}=2\sqrt{5} \ units

b) La distancia entre P y R viene dada por:

QR=\sqrt{(9-3)^2+(2-6)^2} =\sqrt{52}=2\sqrt{13} \ units

The total price of an article is $7.02, including tax. If the tax rate is 8%, what is the retail price of the article?
masya89 [10]
Lets price of article = x
Tax  is 8%  of article = 0.08x

x+0.08x=7.02
1.08x=7.02
x=7.02/1.08 
x=6.5
The retail price is $6.50.

If f(x) = 3^2 + 10x and g(x) = 2x-4, find (f-g)(x).
Marat540 [252]

What we know:      

f(x)=3^2+10x\\g(x)=2x-4                

(Also, 3^2=9)

What we need to solve:

(f-g)(x)             (This is equal to f(x)-g(x))

How you have to subtract f(x) with g(x) to get:

(f-g)(x) = f(x)-g(x) = 9+10x+2x-4 = 12x+5

Thus, the answer would be:

12x+5

Im trash at math sorry
balu736 [363]

Answer:

Step-by-step explanation:

Use vertical angles to help solve the problem. Angles that are across from each other are congruent. For exmaple,  <2 = 85 degrees because the angle across from it is 85 degrees. I assume angle 1 is 95 degrees, so angle 3 would also be 95 degrees.
