Answer:
2 feet per second is faster.
Step-by-step explanation:
2 seconds per foot would also equal half a foot per second, which is less than 2 feet per second.
Pablo swims 1 length of a swimming pool. What unit would be best for measuring that length of the pool?
Answer:
kiloliters
Step-by-step explanation:
The amount of water a family uses in a year is a large amount of water - more than the amount of water in a pool! This means kiloliters would be the best unit of measurement.
What is the equation of the line that passes through (4, -1) and (-2, 3)?
Answer:
3--1/-2-4=4/-6=2/-3
y=-2/3x+b
-2*-2/3=4/3
3-4/3=5/3
y=-2/3x+5/3
Step-by-step explanation:
Answer:
[tex]\displaystyle y=-\frac{2}{3}x+\frac{5}{3}[/tex]
Step-by-step explanation:
We want to find the equation of the line that passes through the two points:
(4, -1) and (-2, 3).
First, we will find the slope of the two points. So:
[tex]\displaystyle m=\frac{3-(-1)}{-2-4}=\frac{4}{-6}=-\frac{2}{3}[/tex]
Now, we will use the point-slope form given by:
[tex]y-y_1=m(x-x_1)[/tex]
Use either point. I'm going to use (4, -1). So, substitute:
[tex]\displaystyle y-(-1)=-\frac{2}{3}(x-(4))[/tex]
Simplify and distribute:
[tex]\displaystyle y+1=-\frac{2}{3}x+\frac{8}{3}[/tex]
Subtract 1 from both sides. Therefore:
[tex]\displaystyle y=-\frac{2}{3}x+\frac{5}{3}[/tex]

Una empresa fabrica dos modelos de DVD: el modelo A y el modelo B. Se dispone de 50 kilogramos de caucho y de 80 horas de mano de obra. Para fabricar un DVD del modelo A se utiliza 1 kilogramo de caucho y 1 horas de trabajo, y para fabricar un DVD del modelo B se utiliza 1 kilogramo de caucho y 2 hora de trabajo. Si la venta le genera una utilidad 30 soles por cada modelo A y 40 soles por cada modelo B. ¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?
Answer:
¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?
Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800
Step-by-step explanation:
x : Número de DVD del modelo A
y : Número de DVD del modelo B.
MODELO A MODELO B TOTAL
Cantidad de caucho 1x 1x 50 kg.
Horas de mano de obra 1x 2x 80 horas
U : Utilidad mensual.
La función objetivo, que se debe maximizar, es:
U=30 + 40y
x+ y [tex]\leq 50\\[/tex]
x + 2y [tex]\leq 80[/tex]
x[tex]\geq 0[/tex]
y[tex]\geq 0[/tex]
Las coordenadas de los vértices de la región factibles son:
A (0, 0) B (50, 0) C (20, 30) D(0, 40)
Entonces, se evalúa la función objetivo en cada punto:
U (0, 0) = 30 (0) + 40 (0) = 0
U (50, 0) = 30 (50) + 40(0) = 1500
U (90, 0) = 30 (20) + 40 (30) = 1800
U (0, 40) = 30 (0) + 40 (40) =1600
Por consiguiente U tiene un valor máximo en C , en donde: x =20 , y = 30 .
Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800.

THIS IS HRW CAN YOU TRY TO HELP!!
Answer:
c
Step-by-step explanation:
Step-by-step explanation:
It's answer is
y = 4x - 6
if x = - 1 Then
y = 4 * (- 4 ) - 6 = - 10
if x = 0
y = 4 * 0 - 6 = - 6
if x = 1
y = 4 * 1 - 6 = - 2
if x = 2
y = 4 * 2 - 6 = 2
hope it will help :)❤

Here is a rectangle all measurement are in centimetres the area is 48cm^2 find the value of y
Answer:
y = 3 cm
Step-by-step explanation:
We'll begin by calculating the value of x. This can be obtained as follow:
2x + 6 = 5x – 9 (opposite side of rectangle are equal)
2x + 6 = 5x – 9
Collect like terms
6 + 9 = 5x – 2x
15 = 3x
Divide both side by 3
x = 15 / 3
x = 5 cm
Next, we shall determine the length of the rectangle. This can be obtained as follow:
L = 2x + 6
x = 5 cm
L = 2(5) + 6
L = 10 + 6
L = 16 cm
Finally, we shall determine the value of y. This can be obtained as follow:
Length (L) = 16 cm
Width (W) = y =?
Area (A) = 48 cm²
A = L × W
48 = 16 × y
Divide both side by 16
y = 48 / 16
y = 3 cm

Find the measure of the missing side of the triangle.
Answer:
65
Step-by-step explanation:
Using Pythagorean we can say = 33^2 + 56^2 = hypotenus^2
so 1089 + 3136 = 4225
and 4225 rooted = 65
Answer:
65.
You would have to use the Pythagorean theorem in order to find the Hypotenuse (Side that is missing)
Step-by-step explanation:
The equation is:
C = a^2 + b^2 - square root of the answer.
So it would be set up like this.
56^2 = 3136
33^2 = 1089
1089 + 3136 = 4225.
The square root of 4225 is 65.
Thus, 65 is the answer.
Hope this helps!

Use special right triangles to solve for all the variables. Leave your answers in simplest radical form.
Answer:
Step-by-step explanation:
x=5[tex]\sqrt{2}[/tex] because it is an isosceles right triangle , as we have and angle of 45 and one of 90
y is the hypothenuse of the triangle
y^2=(5[tex]\sqrt{2}[/tex])^2+(5[tex]\sqrt{2}[/tex])^2=50+50=100
y=10
the larger triangle is 30-60-90
side opposite of 90 degrees is 2y
r=20
side opposite of 60 degrees is y[tex]\sqrt{3}[/tex]
z=10[tex]\sqrt{3}[/tex]

Write the equation of the parabola that has the vertex at point (-2, -2) and passes through the point (-1, -1)
Answer:
y = (x+2)²-2
Step-by-step explanation:
Use the vertex form y = a(x-h)²+k. Plug in the vertex for h and k. Solve for a and you will get 1 for that value. You can check your answers by plugging in both of those points to make sure.
