The expression in scientific notation is given as follows:
3.5 x 10³.
<h3>What is scientific notation?</h3>
A number in scientific notation is given by:
With the base being 
.
For this problem, the expression is given by:
When two factors of a multiplication have the same base and different exponent, we <u>keep the base and add the exponents,</u> hence:
5 x 4.2 = 21, hence the expression is:
When we divide two terms with the same base and different exponents, we keep the base and subtract the exponents, hence:
Which is the simplified expression.

X| 1 | 15 | 225 |
y| 4 | ? | 900 |
therefore
[tex]\dfrac{4}{1}=4;\ \dfrac{900}{225}=4;\ \dfrac{?}{15}=4\to?=60[\tex]
Answer: ? = 60
Answer:
A
Step-by-step explanation:
Nonlinear would be any function where both values are not changing by some fixed amount. In B, f(x) increases by 1 for every time x increases by 1 so that's linear. For C, f(x) increases by 2 for every time x increases by 1, so that's linear. For D, f(x) increases by 3 for every time x increases by 1 so that's also linear. For A, f(x) does not always change by the same amount, so it's nonlinear.
Step-by-step explanation:
The snowplow's speed is 40 mph minus the loss from the snow, which is 1.2 mph times the depth of snow in inches.
y = 40 − 1.2x
When y = 0:
0 = 40 − 1.2x
1.2x = 40
x = 33 ⅓
The snowplow stops moving when the snow is 33 ⅓ inches deep or more.
