Answer: 
Step-by-step explanation:
It is important to remember that the fourth digit after the decimal point is in the ten-thousandth place.
Then, given the following number:

You can follow these steps in order ti round it to the nearest ten-thousandth:
1. You can identify that the digit in the ten-thousandth place is:

2. Identify the digit to the right of
. This is:

3. Since:

You must round up. Increase the digit
by 1. (Notice that
, then the digit to the left of
increases by 1 too). Then:

Answer: OPTION A.
Step-by-step explanation:
You can observe that in the figure CDEF the vertices are:

And in the figure C'D'E'F' the vertices are:

For this case, you can divide any coordinate of any vertex of the figure C'D'E'F' by any coordinate of any vertex of the figure CDEF:
For C'(-8,-4) and C(-2,-1):

Let's choose another vertex. For E'(8,8) and E(2,2):

You can observe that the coordinates of C' are obtained by multiplying each coordinate of C by 4 and the the coordinates of E' are also obtained by multiplying each coordinate of E by 4.
Therefore, the rule that yields the dilation of the figure CDEF centered at the origin is:
→
So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
Answer:
P = 14.4
Step-by-step explanation:
Multiply out -3.1(6) and -2.1(2).
P - 18.6 = - 4.2
Add - 18.6 to the other side of the Equation.
P = 14.4
In this question , it is given that a weather balloon is launched from a height of 475 feet above sea level. the balloon rises at a constant rate of 85 feet per minute.
Here we use the slope intercept form, which is

Where, y is the height h, x is the time, t. And m represents slope, which is 85.
b represents the initial height , which is 475 feet.
On substituting these values, we will get

And at t = 16 minutes, we will get
