This question needs more information like where point E is but I'm going to assume that point E is directly below point D
With that assumption, angle EDF should be (90°- 25°) which is 65°
tan 65° = opposite/adjacent
tan 65° = 10 yd/ DE
DE = 10 yd/tan 65°
DE = 4.7 yd (to the nearest tenth)

Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3
Step-by-step explanation:
In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.
Then the correct option is d.
Where the degree of the first term is (4 + 1) = 5
The degree of the second term is (2 + 2) = 4
The degree of the third therm is 3.
We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:
-3*x^4*y + 2*x^2*y^2 + 5*y^3
Answer:
-24
Step-by-step explanation:
12 (x+9)=-180
12x+108=-180
12x=-180-108
12x=-288
12x/12=-288/12
x=-24

before retirement; this is not yet too late to start. If Joyce will put her money in the bank, the
highest interest would only be 1%, minus interest depending on her
savings. Investing in the stock market
can also be a great choice. The best
choice would be investing in a business venture in a reputable company.</span>
