Answer:
25
Step-by-step explanation:
The increments are 0.4, and the width of the interval is 10, so the number of increments (the number of times you need to use Euler's method) is:
10 / 0.4 = 25
Answer:
a)-6(x-2) = 4r-17
B) 10x +307 - 20) = 13-20
6) (18-19) -(4-720) = -73
г)-3(4-5y)+2(3-6y)=-39
<h3>Answer: RS = 16</h3>
========================================
Explanation:
The ratio QR : RS : ST is equal to 1 : 4 : 5
This means we have the following three equations
For some positive number x.
Note the ratio QR : RS : ST turns into x : 4x : 5x, which reduces to 1 : 4 : 5 when we divide all three parts by x
.
Along with those three equations, we'll also use QT = 40 as well.
Now turn to the segment addition postulate. Plug in the equations mentioned earlier, and solve for x
.
QT = QR + RS + ST
40 = x+4x+5x
40 = 10x
10x = 40
x = 40/10
x = 4
So we know that
QR = x = 4
RS = 4x = 4*4 = 16
ST = 5x = 5*4 = 20
-----------
As a check,
QR + RS + ST = 4 + 16 + 20 = 40
which is the same as QT = 40
Therefore, we've confirmed that QR + RS + ST = QT is correct and we've confirmed our answers.
