A number multiplied by a power of 10 makes the decimal point move to the right as many as there is zeroes in the power of 10: for example, 1*10=10, 5.5*100 = 550.
In your case:
a) 4301 = 430.1 * 10 = 43.01 * 100 = 4.301 * 1000... more the decimal point goes backward, the more zeroes you add to the power of 10.
b) 687 = 68.7 * 10 = 0.687 * 1000 = 0.0687 * 10 000, if the decimal point goes beyond the last number, you add zeroes to the left before the decimal point.
c) Same thing here! 56 = 5.6 * 10 = 0.56 * 100, etc..
Hope this helps! ;)
Answer:
B.8
Step-by-step explanation:
The degree of a polynomial refers to the term with the highest exponent. Thus the highest exponent in a degree 3 polynomial is x3; for a degree 5 polynomial, it's x5. When you multiply
x3*x5 = x3+5 = x8.
So the product of a degree 3 polynomial and a degree 5 polynomial is a degree 8 polynomial.
Your leading term will result from the 3-degree term of the first polynomial, and the 5-degree term of the second. So you'll have something like ax3 * bx5. That will result in x3*x5=x8, so your product will have degree 8.
The slope-point form:
We have two points (4, 5) and (-3, -1). Substitute:
For point (4, 5):
For point (-3, -1):
There were 11 birds at the shelter on Wednesday.
Step-by-step explanation:
Cost of care for one bird = $4.00
Cost of care for one cat = $8.00
Total spent = $148.00
Total birds = 24
Let,
Number of birds = x
Number of cats = y
According to given statement;
x+y=24 Eqn 1
4x+8y=148 Eqn 2
Multiplying Eqn 1 by 4
Subtracting Eqn 3 from Eqn 2;
Dividing both sides by 4
Putting y=13 in Eqn 1
There were 11 birds at the shelter on Wednesday.
