What is the product? -3 4 2 -5 3 -2 1 0
Final answer:
The product of the provided series of numbers is 0, because multiplying any number by zero will always result in zero.
Explanation:
The product of a series of numbers is the result of multiplying all the numbers together. In this case, you have provided a list of numbers: -3, 4, 2, -5, 3, -2, 1, 0. To find their product, we multiply them one by one.
Multiplying any number by zero results in zero, which is an important mathematical rule. Since one of the numbers in the list is 0, the product of these numbers is 0 regardless of all other numbers.

solve this equation 0.5x-0.3=0.2
Answer:
x = 1
Step-by-step explanation:
0.5x-0.3=0.2
1. Multiply both sides by 10.
0.5x*10-0.3*10=0.2*10
2. Refine.
5x-3=2
3. Add 3 to both sides.
5x-3+3=2+3
4. Simplify.
5x=5
5. Divide both sides by 5.
5x/5=5/5
6. Simplify.
x=1
Answer:
Step-by-step explanation:
0.5x - 0.3 = 0.2
add 0.3 to both the sides
0.5x - 0.3 + 0.3 = 0.2 + 0.3
0.5x + 0 = 0.5
0.5x = 0.5
[tex]x=\frac{0.5}{0.5}\\\\x = 1[/tex]

Determine the x-intercepts of the function. Check all
that apply.
(-2,0)
(-1, -2)
(0,0)
(1,0)
(2,0)
The x-intercepts of the function are (0,0) and (-2,0). Therefore, options A and C are correct.
What is an intercept?To determine the x-intercepts of a function, we need to find the values of x when the function value, f(x), is equal to zero. Therefore, we need to plug in 0 for f(x) and solve for x.
From the given points, we can see that the function passes through the points (-2,0), (0,0), and (1,0), (2,0). Therefore, the x-coordinates of these points are the possible x-intercepts of the function.
Setting f(x) to zero for each of the points, we get:
At (-2,0): f(-2) = 0, so x = -2 is an x-intercept.
At (-1,-2): f(-1) = -2, so x = -1 is not an x-intercept.
At (0,0): f(0) = 0, so x = 0 is an x-intercept.
At (1,0): f(1) = 0, so x = 1 is an x-intercept.
At (2,0): f(2) = 0, so x = 2 is an x-intercept.
Therefore, the x-intercepts of the function are (0,0) and (-2,0).

A rectangular pyramid has a height of 10 meters. The base measures 8 meters in length and 12 meters in width. Two different triangular cross sections are formed through the vertex and perpendicular to the base. What is the difference in the areas of the cross sections?
If someone is able to help me fast that would be great!!!
Step-by-step explanation:
(i) Area of the first cross section
base,b = 8 m, height,h = 10 m
Area of the triangle = [tex]\frac{1}{2}[/tex] bh
area = [tex]\frac{1}{2}[/tex] (8) (10)
area = 40 m²
(ii) Area of the second cross section
base,b = 12 m, height,h = 10 m
Area of the triangle = [tex]\frac{1}{2}[/tex] bh
area = [tex]\frac{1}{2}[/tex] (12) (10)
area = 60 m²
Difference in the areas of the cross sections = 60 - 40 = 20 m²
Solve Thais equation
2x=8(4x-5).
Answer:
[tex]x = \frac{40}{-30\\}[/tex]
Step-by-step explanation:
Lets start by working with our numbers on the right side of the equation.
Begin by using distributive property, turning:
2x = 8(4x - 5) into 2x = 32x - 40
To make things easier, lets subtract 32x on both sides
-30x = 40
Finally, divide by -30 on both sides to get our answered, simplified if necessary:
[tex]x = \frac{40}{-30} = \frac{4}{-3} = -1.33[/tex]

Aponi built a toy chest for her niece. It has a volume of 12 cubic feet, the chest is 3 feet long and 2 feet wide. How deep is it?
Answer:
The chest is 2 feet deep.
Step-by-step explanation:
Given:
Aponi built a toy chest for her niece. It has a volume of 12 cubic feet, the chest is 3 feet long and 2 feet wide.
Now, to find the depth of it.
Length = 3 feet.
Width = 2 feet.
Volume = 12 cubic feet.
Now, to find the depth by using formula:
[tex]Volume= length\times width\times depth\\\\12=3\times 2\times depth\\\\12=6\times depth\\\\Dividing\ both\ sides\ by\ 6\ we\ get:\\\\2=depth\\\\Depth=2\ feet.[/tex]
Therefore, the chest is 2 feet deep.

Express your answer in terms of
what is the value of x?
Answer:
The value of x is 40.
Step-by-step explanation:
These are vertical angles meaning that these are both the same angle. We can express this into an equation. (3x - 6) = 114, usually with an equation like this we add the 6 from (3x - 6) and also add it to 114 because whatever you do to one side of the equation you have to do to the other. Because we added 6 to (3x - 6) the 6 from there is gone and since we added 6 to 114 it is now 120 so now the equation is 3x = 120. Now we divide each side me 3 to get the value of x. 3x divided by 3 is x. 120 divided by 3 is 40. So now our equation looks like this, x=40. So this is how the value of x is 40. Let me know if it's right!!

Answer:

Step-by-step explanation:
Let P(H)=p be the probability of one head. In many scenarios, this probability is assumed to be p=12 for an unbiased coin. In this instance, P(H)=3P(T) so that p=3(1−p)⟹4p=3 or p=34.
You are interested in the event that out of three coin tosses, at least 2 of them are Heads, or equivalently, at most one of them is tails. So you are interested in finding the likelihood of zero tails, or one tails.
The probability of zero tails would be the case where you only received heads. Since each coin toss is independent, you can multiply these three tosses together: P(H)P(H)P(H)=p3 or in your case, (34)3=2764.
Now we must consider the case where one of your coin flips is a tails. Since you have three flips, you have three independent opportunities for tails. The likelihood of two heads and one tails is 3(p2)(1−p). The reason for the 3 coefficient is the fact that there are three possible events which include two heads and one tails: HHT,HTH,THH. In your case (where the coin is 3 times more likely to have heads): 3(34)2(14)=2764.
Adding those events together you get p3+3(p2)(1−p)=5464. Note that the 3 coefficient

The are of the given heptagon is 243 u³.
In the given polygon,
Number of sides = 7
Hence this is a heptagon, which has,
Length of edge = 9 unit
Polygons are two-dimensional geometric figures with a fixed number of sides. A polygon's sides are made up of straight line segments that are joined end to end. As a result, the line segments of a polygon are referred to as sides or edges.
Since we know that,
Area of heptagon = (7 / 4) × edge² × cot(π/7)
Therefore,
Area of heptagon = (7 / 4) × 9² × cot(π/7)
= (7/4) x 81 x 2.07
≈ 243 u³
Hence,
The area is approximately 243 u³

Solve the system of equations.

PLZ HELP!!!!!!!!!!
Answer:
y=3,x=1.3,z=6.2 :)
Step-by-step explanation:
y=3,x=1.3,z=6.2 :)
So, we have:
: x+y+z=10 [equation 1]
: 5x+3y=14 [equation 2]
: x−2y+z=2.5 [equation3]
(I'm going to assume that you know how to solve equations with 2 variables)
1. eliminate a variable to get 2 variables
Let's reverse equation 2:
-x+2y-z= -2.5
and take equation 1, to try to eliminate "z"
x+y+z=10
add up the 2 equations to get:
3y=7.5
and solve to get
y=2.5
2. substitute what we already solved into another equation
Luckily, equation 2 only has 2 variables, and one is y, so we can sub it in.
5x+3y=14 --> 3x+3(7.5)=14
solve to get
x=1.3
3. Substitute both of our variables in to get the final variable: z
Let's take the first equation.
x+y+z=10 --> 1.3+2.5+z=10
solve to get
z=6.2
I hope this helps you!
