Answer:
C
Step-by-step explanation:
Given
x² - 10x + 24 = 0
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 4 and - 6, since
- 4 × - 6 = + 24 and - 4 - 10 = - 10, hence
(x - 4)(x - 6) = 0 ← in factored form → C
Cosine stands for "complementary sine." The sine of an angle is the cosine of the complementary angle and vice versa. Complementary angles add to 90°.
Answer: sin(B) = cos(90 - B)
It's true for any angle, and it doesn't have much particularly to do with a triangle.
A) The bottom section for D equals 0.34.
b) The top section for B equals 3/20 as a faction
Deniz made a mistake in step 2. He tried to use the associative property to group certain terms together, however, to do to that they must have the same variable and exponent. 3r^2 can be combined with 5r^2 but neither of them can be combined with 9r or 7r because those two aren't squared. The correct answer would be:
(3+5)r^2+(-9-7)r+(3+2)
8r^2-16r+5 is your answer
Hope this helped!
All you have to do is divided 43.54 divided by 3.5 which is 12.44 mph
