When is the turning point/climax in the book "Zinnia and the Bees?"
4. What are the coefficients in the polynomial 5x² + 2x-4? (1 point)
O 5, 2
O -5, -2
O 5, 2, -4
O 5, -2, -4
?
The coefficients in the polynomial 5x² + 2x - 4 are 5, 2, and -4.
Therefore, the answer is: 5, 2, -4.
Add or subtract.
5. (m²-m-4)+(m-5) (1 point)
1 m² - 2m + 9
2 m² + 2m - 9
3 m² - 2m - 9
4 m² - 9
?
To add (m² - m - 4) and (m - 5), we combine like terms and simplify:
(m² - m - 4) + (m - 5)
= m² - m + m - 4 - 5
= m² - 9
Therefore, the answer is: 4. m² - 9.
Add or subtract.
6. (7x^2-x-2)-(-6x^3 + 3) (1 point)
A 6x^3+7x2-x-5
B -6x^3+7x2-x+1
C -x^3-x-5
D x²-x+1
?
To subtract (-6x³ + 3) from (7x² - x - 2), we must first distribute the negative sign to all terms inside the parentheses:
(7x² - x - 2) - (-6x³ + 3)
= 7x² - x - 2 + 6x³ - 3
We can simplify the answer by combining like terms:
= 6x³ + 7x² - x - 5
Therefore, the answer is: A) 6x³ + 7x² - x - 5.
8. f^2 . f^4 (1 point)
A (2f)^8
B (2f)^6
C f^8
D f^6
?
When multiplying exponential expressions with the same base, we must add their exponents.
In this case, we have f^2 and f^4. Adding their exponents, we get:
f² . f⁴ = f^(2+4) = f^6
Therefore, the answer is: D. f^6
9. 144^14/144^2
(1 point)
A 144^16
B 144^12
C 144^28
D 144^14/2
?
When dividing exponential expressions with the same base, we must subtract their exponents.
In this case, we have 144^14 in the numerator and 144^2 in the denominator. Subtracting their exponents, we get:
144^(14-2) = 144^12
Therefore, the answer is: B. 144^12.
