Coefficients are the numbers in from with the variable, the constant is just a number and the degree is the exponent.
Answer:
Step-by-step explanation:
Q3.
If ΔGHI and ΔJKL are similar, then the sides are in proportion:
We have
JL = x, GI = 9 ft, LK = 24 ft, IH = 12 ft.
Substitute:
<em> multiply both sides by 2</em>
Q4.
We must multiply the original length by a scale factor of 3/4:
Y=29
x+y+78=180
x+29+78=180
x=180-78-29
x=73
z=180-73
z=107
x=73 degrees
y=28 degrees
z=107 degrees
40,000 = 4 * 10^4
0.000004 = 4 * 10^-6
The power of 10 exactly in between 4 and -6 is -1.
She started with 4 * 10^(-1) which is 0.4.
0.4 * 100,000 = 40,000
0.4/100,000 = 0.000004
The number she started with is 0.4.
The power is 10^5.
