Answer:
Option 1st is correct
area of a triangle is, 80 in²
Step-by-step explanation:
Area of triangle(A) is given by:
where,
b is the base
h is the height or altitude of the triangle respectively.
As per the statement:
Base of a triangle(b) = 10 inches and
Height = altitude(h) = 16 inches
Substitute these in [1] we get:
⇒in²
Therefore, the area of a triangle is, 80 in²
B)Meiosis in the sporophyte would cease and the reproductive cycle would stop.
C)The flagellated sperm would not be able to swim to the eggs for fertilization.
D) The flagellated sperm and eggs would go dormant until water was available.
2. Which of the following is true of conifers?
A)The sporophytes grow directly from the gametophyte B)The gametophytes grow directly from the sporophyte C) The spores release from the male cones D)The spores release from the gametophyte
they? (Round to the nearest tenth).
A) 76.2 ft
B) 14.1 ft
C) 70.7 ft
D) 31.6 f
Which of the following arithmetic sequences have a common difference of 2 1/2
Answer: -4,-1.5,1,3.5,6,8.5
Step-by-step explanation: You can check that the difference of any of its consecutive terms is always equal to 2.5.
8.5 - 6 = 2.5
-1.5 - (- 4) = 2.5
3.5 - 1 = 2.5
|4r + 8| ≥ 32
|4r + 8| ≥ 32
4r + 8 ≥ 32 or 4r + 8 ≤ -32 inside of absolute value could be + or -
4r ≥ 24 or 4r ≤ -40 subtracted 8 from both sides
r ≥ 6 or r ≤ -10 divided both sides by 4
Graph: ←---------------- -10 6 ------------------→
Interval Notation: (-∞, -10] U [6, ∞)
Okay here are the steps to solving this inequality:
First- Break down the problem into these 2 equations
4r + 8 ≥ 32 → - (4r + 8) ≥ 32
Second- Solve the 1st equation: 4r + 8 ≥ 32
r ≥ 6
Third- Solve the 2nd equation: - (4r + 8) ≥ 32
r ≤ -10
Lastly- Collect all solutions

Answer:
Option C. (4x² -3x + 9)
Step-by-step explanation:
Arranging a polynomial in descending order means to arrange the powers of variables of each term in the descending order.
So in the given options only Option C. is in the descending order.
4x² - 3x + 9
This polynomial has the variable x² with maximum degree of 2 at the starting.
Then second variable 3x with degree of 1 and then constant term 9.
Option C. is the correct option.
