So a times 10^n where 1≤|a|<10 and n is an integer is what i learned
so
a.
234=
2.34 times 100=
2.34 times 10²
b.
0.000052=
5.2 times 1/100000=
5.2 times 10⁻⁵
c.
-220000=
-2.2 times 100000=
-2.2 times 10⁵
d. ok, so just count the spaces moved to the left
-18.2 times 10⁻¹⁵
Answer:
The expression that can be used is 0.80x
Step-by-step explanation:
Let
x ----> original price of an item
Remember that
That means---> the sale price is 80% of the original price
To find out the sale price, determine the 80% of the original price
----> percentage in decimal form
Multiply the original price by the percentage in decimal form to obtain the sale price
so
C, since the radius is 10 multiply by 2 and 100 x 3.14 is 314
Answer:
The equation of the line would be y = 3x - 10
Step-by-step explanation:
To find the equation we first need to note that parallel lines have the same slope. So since the original equation has a slope of 3, the new one will as well. Now we can use that slope and the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y + 4 = 3(x - 2)
y + 4 = 3x - 6
y = 3x - 10
