Dialation ratio is 1:6
4:24(4*6=24)
6:36(6*6=36)
Answer: C)36 in.
X=number of boys in the club at first
y=number of girls in the club at first.
(x+y) = members were in the club at first.
We can suggest the next system of equation.
x/y=1/2 ⇒ x=y/2
(x+5)/y=3/4 ⇒4(x+5)=3y
Finally, we have the next system of equations:
x=y/2
4(x+5)=3y
We are going to solve by substitution method.
4(y/2 + 5)=3y
2y+20=3y
2y-3y=-20
-y=-20
y=20
x=y/2
x=20/2
x=10
(x+y)=10+20=30
Answer: There were 30 members int the club at first, they were 10 boys and 20 girls.
Answer:
Required equation of tangent plane is .
Step-by-step explanation:
Given surface function is,
To find tangent plane at the point (5,-1,1).
We know equation of tangent plane at the point $(x_0,y_0,z_0)[/tex] is,
So that,
Substitute all these values in (1) we get,
Which is the required euation of tangent plane.
Step-by-step explanation:
the stem-and-leaf diagram only looks at the last digit (for the leaves) and all the digits before (for the stem). so, we have to put a "key" or "legend" on this diagram to show what we mean by the numbers in this plot. the ones digits will be the stem values, and the tenths will be the leaves.
the key would be :
key: "1 | 2" means "1.2"
we see that all numbers start with either 1, 2. 3, 4 or 5.
these are our rows. and each of these starting numbers is the stem of its row. the numbers are the decimal point are the leaves.
so, we get (ordered ascending)
1 | 2 2 6 7 8
2 | 2 2 6 9
3 | 2 3 3 4 7
4 | 2 3 4 4 4
5 | 0 2 3 5 6
