Answer:
16pi or 50.2
Step-by-step explanation:
formula for area of a circle is pi * radius squared. Since the diameter is 8 you divide that by 2 to get 4 and you square it so it becomes 16. Then you multiply it by pi or 3.14 to get 50.24 and then you round.
1. To find this we are going to use the converse of the Pythagorean theorem: if the square of the longest side of a triangle is equal to the sum of the squares of its smaller side, the triangle is a right one.
We know from our picture that the longer side of the triangle is 36 and its shorter sides are 24 and 15.
The converse also says that if the square of the longest side is greater than the sum of the squares of the shorter sides, the triangle is
obtuse, and if the square of the longest side less than the sum of the squares of the shorter sides, the triangle is
acute.
We can conclude that our triangle is an obtuse one; the correct answer is the third one:
obtuse2. Here we have a right triangle with longer side 80 feet and one of the shorter sides 65 feet. Lest
be the distance from the base to the guy wire attached point.
Using the Pythagorean theorem:
We can conclude that the correct answer is fourth choice:
46.64
3. Here we are going to use the Pythagorean theorem. We know that the longest side of our triangle is 40 and its shorter sides are 9 and
. Using the Pythagorean theorem:
We can conclude that the correct answer is the fourth option:
38.97
Answer: p = 278 + 142
Step-by-step explanation:
From the question, we are informed that Allison picked up 278 pecans from under one tree and 142 pecans from another tree.
The equation that Allison could use to find p, the numbers of pecans she picked up in all will be the addition of 278 and 142. This will be:
p = 278 + 142
The equation is p = 278 + 142
Answer:
The answer is C.
Step-by-step explanation:
You can do it by solving both equations :
y = x³ - 8
Let y=0,
x³ - 8 = 0
x³ = 8
x = ³√8
= 2
x² + 5x + 6 = 0
(x+3)(x+2) = 0
x = -3
x = -2
So the domain for 1st equation is 2 and 2nd equation is -2 & -3.
In 1st equation, the answer cannot be option A & B and in 2nd equation, the answer is B.
pretty sure its E
just substitute x and z for a and c
hope it helps
