Answer:
A value that satisfies this equation is called a root, zero or solution of the equation!! We have three ... Solve each by factoring. 1) x2 + 4x -5 = 0 ... Follow the explanation and sample problem to review completing the square.
Step-by-step explanation:
x^2 - 4x = 80
x^2 - 4x + 4 = 80 + 4 (Divide b, which is 4, by 2 and square it.)
x^2 - 4x + 4 = 84
sqrt(x + 2)^2 = sqrt(84)
x + 2 = plus or minus sqrt(84)
Subtract 2 from both sides
x = -2 plus or minus sqrt(84)

Which step is included in the graph of the function f(x)=[x-1]? (the brackets are ceiling functions symbols)
Answer:
The correct step is y = - 5 for, - 4 ≤ x < - 3.
Step-by-step explanation:
From the definition of a box function y = [x], we know that
y = 0 for, 0 ≤ x < 1
y = - 1 for, - 1 ≤ x < 0
y = - 2 for, - 2 ≤ x < - 1
Here, we are given another box function y = [x - 1], and we have to choose from options the steps which is included in the graph of the this function.
So, the correct step is y = - 5 for, - 4 ≤ x < - 3. (Answer)

A right prism has a base that is an equilateral triangle. The height of the prism is equal to the height of the base. If the volume of the prism is 81, what are the lengths of the sides of the base?
Length of side of base is 5.45
Step-by-step explanation:
Step 1: Volume of a right prism = Area of the base × Height = 1/2 × base × height of base × height of prismHere, since the base is an equilateral triangle and it is given that height of the prism is equal to that of the base, measures of base and height are equal.
⇒ Volume = 1/2 × b × h × h (b and h are equal)
⇒ 81 = 1/2 × b³
⇒ b³ = 162
⇒ b = ∛162 = 5.45

Answer: [tex]\frac{1}{4}\ cups[/tex]
Step-by-step explanation:
For this exercise it is important to analize the information given in the exercise.
According to the data provided in the exercise, the recipe says that [tex]\frac{1}{2}\ cups[/tex] of Parmesan serves four people.
The, let be "x" the amount of cups of Parmesan cheese that Cordelia will use for her brother's proposal dinner.
In this case, since the proposal dinner is for two people, you can set up the following proportion:
[tex]\frac{4}{\frac{1}{2}}=\frac{2}{x}[/tex]
Finally, you must solve for "x" in order to find its value, as you can observe below:
[tex]8=\frac{2}{x}\\\\8x=2\\\\x=\frac{2}{8}\\\\x=\frac{1}{4}[/tex]
Therefore, knowing the value of "x", you can determine that Cordelia will use [tex]\frac{1}{4}\ cups[/tex] of Parmesan cheese for the proposal dinner.
what did the beaver say to the tree
Answer:
It’s been nice gnawing you
Step-by-step explanation:
While beavers don't 'speak' to trees in human terms, they interact with them by using their teeth to fell trees for food and building materials.
Explanation:The question, 'what did the beaver say to the tree?', is somewhat humorous due to its anthropomorphic implication of a beaver communicating with a tree in human language. But, from a biological perspective, we could interpret this as asking about the interactions between beavers and trees. Beavers, as known dentition specialists, utilize trees for building dams and lodges and as a source of food. So, if a beaver could 'speak', it might 'tell' the tree that it's hungry, or that it needs materials for its dam. Of course, this is all figuratively speaking.

If the weight of a package is multiplied by 2/3 the result is 40 pounds. Find the weight of the package.
all you do is divide 40 by 2/3 to get the answer :D
Answer: Weight is 60
Explanation:
So lets look at what we are given:
w (weight) * 2/3 = 40 pounds
(short explanation is you times 40 by 3/2)
We want to solve for weight there are a few ways to do this but the easiest one is to times both sides of the equation by the reciprocal of 2/3. Which is 3/2. That will cancel our the 2/3 and leave only "w" on the left side.
w = 40 * 3/2

A total of $170.86 will be spent if you buy shirts for $44.11
Step-by-step explanation:
Step 1:
Let the cost of shirts be $x.
Given that, one pair of jeans costs $39.95, 2 pairs cost 2 * $ 39.95 which is $79.9. Jacket costs $45.99.
Step 2:
Create an equation with this given data.
$170.86 = $x + $79.9 + $45.99
Step 3:
Calculate the value of x from this equation to get the cost of shirts.
$170.86 = $x + $125.89
$x = $170.86 - $125.89
$x = $44.11

3. Find the area of the triangle.
A. 21.2 in
B. 10.5 in
C. 21 in
D. 42 in
Answer:
C. 21 in² . . . . your answer selection is correct.
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
where b represents the base of the triangle, and h represents the height of the opposite vertex above that base.
The figure shows you that half the base is 3 in and the height is 7 in, so the area is ...
A = (1/2b)h = (3 in)(7 in) = 21 in² . . . . matches choice C

A new species of fish is released into a lake, and the fish multiply quickly. The growth of their population is modeled by the exponential function P(t) = 7bt, where t is the time in weeks after the release and b is a positive unknown base. According to the model, how many fish of the new species were released initially? A) 2 B) 7 C) 12 D) 14
The initial amount of fish released would be the number shown in the equation.
The answer is 7
Final answer:
The initial number of fish released into the lake is 7, which is calculated by substituting t = 0 into the provided exponential growth function, P(t) = 7bt.
Explanation:
The growth of the fish population in the lake is modeled by the exponential function P(t) = 7bt, where t is the time in weeks after the release, and b is a positive unknown base. To find out how many fish were released initially, we need to consider the population at time t = 0. When we substitute t = 0 into the exponential function, we get P(0) = 7b0, and since any number raised to the power of 0 is 1, P(0) = 7. Therefore, the initial number of fish released was 7.
