Answer:
30 questions
Step-by-step explanation:
if you cross multiply and divide like this,
27 x 100 = 2700
2700 / 90 = 30
you'll get ; 30 !
(a) <em>Slope and intercept
</em>
In the equation y = 2x +8, the coefficient of x is the slope and the constant is the y-intercept.
Thus,
slope = 2; y-intercept = 8
===============
(b) <em>Rate of change and initial amount
</em>
The rate of change is the slope. The units of y are baskets of apples and the units of x are hours. So,
rate of change = 2 baskets of apples per hour
The initial amount when x = o.
When x = 0, y = 8. so
Initial amount = 8 baskets of apples
===============
(c) <em>Graph
</em>
Your graph should look something like the one below.
Answer:
Diane has a booth at the state fair that sells bags of popcorn she has found that her daily costs are approximated by the function c(x) =x squared -20x+150
a) How many bags of popcorn must Diane sell to minimize her cost?
b) What is Diane’s minimum cost?
a) 10
b) 50
Step-by-step explanation:
According to the quadratic equation given in the question ,
the cost will be minimum at
comparing x^{2} -20x+150[/tex] with the standard quadratic equation
we get
a= 1, b = -20, c=150
now
Hence to minimize her cost, she must sell
a) x= 10 popcorns
and her minimum cost is
b)
We know that
circumference=2*pi*r
for r=5 cm
circumference=2*pi*5-----> 31.4 cm
if 360° (full circle) has a length of------------> 31.4 cm
225°-----------------------------> X
X=225*31.4/360-----> X=19.625-----> x=19.63 cm
the answer is
19.3 cm
