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.

Answer:
2 cm is were youll find the polygon at. it shouldnt be hard to see the area of were the polygon is
Im thinking 10 because 10+40=50 and 10x7=70
Answer:
12/13
Step-by-step explanation:
The cosine of an angle in a triangle can be calculated as a relation between the adjacent side and the hypothenuse. So, in this case the adjacent side of θ is 24 and the hypothenuse is 26.
Then:
cos(θ) = 24/26 = 12/13
I did not get any zeros since the graph doesn’t cross the x axis, meaning that there are no rational zeros
However, here is the method u can use to find the zeros lol
You can use the quadratic formula in order to get the zeros
This is the equation therefore use these values
ax^2+bx+c=0
A=1
B= -5
C=12
The quadratic formula is -b±√(b^2-4ac))/2a (I left a picture just in case)
