Answers:
- Standard form =
- Degree = 5
- Leading coefficient = 3/5
===================================================
Explanation:
The largest exponent term is what will go first. Then the term with the second largest goes next, and so on. We count the exponents down. The exponents will count down in this case as 5, 3, 1, 0
Note: -9 = -9*1 = -9m^0 and -11m = -11m^1
So that's why standard form is
We can write this as (3/5)m^5 + 7m^3 - 11m - 9
------------------------
The leading term is the first term after getting everything in standard form. The coefficient of the leading term is the leading coefficient. So in this case, it would be 3/5.
The degree is the largest exponent. So the degree is 5. This is a quintic polynomial.
Simple Interest Formula
I=Prt P=principal; r=rate in decimals; t=years
I=Prt ; find t
299=1300(.0575)t
299=74.75t
299/74.75=74.75/74.75t
4=t
It took Bonita 4 years to earn 299 in interest.

Answer: Choice C) $1125</h3>
==============================================================
Explanation:
We'll add up the values in the bottom row of the table.
A value like +150 is the same as simply saying 150
The negatives stick around.
Adding up the values in that row gets us
150 + (-50) + 400 + 300 + (-175) + (-250) = 375
This indicates that over the entire 6 month period, the overall change is +375
---------
In other words, the initial investment (call it x) has increased by 375 dollars over the 6 month period.
We can then say:
x + 375 = 1500
x = 1500-375
x = 1125
She initially invested $1125
Answer:
27.50 * 0.2 (20%) = 5.5 (discount)
27.50 - 5.5 = $22

Answer:
Step-by-step explanation:
a) Angle CAE can be found using the tangent relation.
tan(∠CAE) = CE/AE
tan(∠CAE) = 6/20
∠CAE = arctan(6/20) ≈ 16.7°
__
b. The length of DF can be found using the law of cosines.
DF² = FA² +DA² -2·FA·DA·cos(A)
DF² = 14² +10² -2·14·10·cos(16.7°) ≈ 27.8086
DF ≈ √27.8086
DF = 5.3
