Wne solved they have different answers
35 - 15 = 20
and
43 - 26 = 17
The answer is 71 since you count from the tenth space. So the first significant figure would be 7 and the second significant figure would be 0. As we know that we round up one number of the previous number is 5 or bigger.
Answer:
$10 coins: 21
$20 coins: 24
Step-by-step explanation:
heyy me again
So we can create 2 equations where
x = number of $10 coins
y = number of $20 coins:
x + y = 45
10x + 20y = 690
we can move equation 1 around so that we can get a value of x
x = 45 - y
now we can substitute x into the second equation
10(45 - y) + 20y = 690
450 - 10y + 20y = 690
10y = 240
y = 24
Now plug in y back into the first equation
x = 45 - y
x = 45 - 24
x = 21
Answer: x² = 4y -8
Step-by-step explanation: The equation of the set of points which are equidistant from a point and from a line is a parabola. In this case:
F ( 0 , 2 ) The parabola open upwards, so is of the form
p = 1
( x - h )² = 4*p* ( y - 2)
x² = 4 * ( y - 2 )
x² = 4y -8
Answer:
The cost of printing 142 more posters when 18 has already been printed is $5.57.
Step-by-step explanation:
We are given that the marginal cost (dollars) of printing a poster when x posters have been printed is given by the following equation C'(x)=x^-3/4.
The given equation is:
The cost of printing 142 more posters when 18 have already been printed is given by;
Integrating both sides of the equation and using the limits we get;
As we know that , so;
=
=
=
=
= $5.57
Hence, the cost of printing 142 more posters when 18 has already been printed is $5.57.
