Answer:
3 whole pizzas
Step-by-step explanation:
So 3 whole pizzas will need to be ordered.
Find
R(V)
- p(x)×x
- x(-3/2x+112)
- -3/2x²+112x
Now
Find vertex x coordinate
Put in equation
- y=-3/2(-37.3)²+112(-37.3)
- y=-2086.9-84+4177.6
- y=$6264.6
- y=$62.64M
As a is negative parabola is facing downwards hence vertex is minimum .
So minimum value is $62M which is far more than given .
Answer:
Step-by-step explanation:
The circular oil slick is expanding at a rate of
Let A be the area of the circular oil slick,
So, the changes in A with respect to time (t),
Also, the change in diameter with respect to time(t),
For r = 1.5 m,
Responder:
15 m e 75 m
Explicação passo a passo:
Deixar :
Largura = x
Comprimento = 5x
Perímetro = 180
Já o terreno tem uma forma retangular; usamos a relação;
Perímetro = 2 (comprimento + largura)
180 = 2 (5x + x)
180 = 2 (6x)
180 = 12x
180/12 = x
15 = x
Largura = x = 15 metros
Comprimento = 5x = 15 * 5 = 75 metros
Medida de largura e comprimento, respectivamente:
15 m e 75 m
Answer:
x=8
Step-by-step explanation:
You move all terms that don't contain x to the right side and solve.
3x-6=18
3x=24
x=8
