Multiply 7 x 462 using place value and expanded form. Choose the number from the box to complete the expression
To multiply 7 x 462 using place value and expanded form, we first write 462 as the sum of the products of its digits and their place values (400 + 60 + 2). We then multiply each component by 7 and add the results to get 3234.
Explanation:
To multiply 7 x 462 using place value and expanded form, you first need to break down the number 462 into expanded form. This means you write it as the sum of the products of its digits and their place values. We start at the right and move to the left: 2 (units), 60 (tens), and 400 (hundreds). So 462 in expanded form is 400 + 60 + 2.
The next step is to multiply each component by 7: 7 x 400 = 2800, 7 x 60 = 420, and 7 x 2 = 14. You add those results together to get your final answer: 2800 + 420 + 14 = 3234. So, 7 x 462 = 3234.

suppose an object is moving 66 feet per second. how fast would you have to drive in your car, in miles per hour, in order to keep up with this object?
You would need to drive at around 96.67 miles per hour to keep up with the object.
Explanation:To determine how fast you would have to drive in your car to keep up with an object moving at 66 feet per second, we need to convert the unit from feet per second to miles per hour. There are 5280 feet in a mile and 3600 seconds in an hour. Therefore, the conversion factor is 5280/3600 = 1.4667. Multiplying 66 by this conversion factor gives us approximately 96.67 miles per hour. So, you would need to drive at around 96.67 miles per hour to keep up with the object.

Use the vertical line test to determine if the relation {(-6, -2), (-2, 6), (o, 3), (3, 5)} is a function. Explain your response.
Using the vertical line test, it is found that the relation is a function.
In the definition of a function, it has that for each input, there can only be one respective output, and the same is true for a relation, and the test of the number of outputs for each input is the vertical line test.
The relation is: {(-6, -2), (-2, 6), (0,3), (3,5)}
No repeated inputs, thus it passes the vertical line test and is a function.

Inductive reasoning involves developing a general rule from specific situations. True or false
Answer:
The answer is true
Step-by-step explanation:
Inductive reasoning is a principle in mathematical and philosophical logic where general conclusions are derived from specific situations. Its contrary is deductive reasoning where we use a general rule to explain particular situations, reasoning commonly used in mathermatics. Example: all right angles measure 90 degrees, AB is right angle so AB measure 90 degrees,
In inductive reasoning we use the opposite logic that can take to incorrect general principles due to a bias. Example, my friend is tall and a good basket player, Joe is tall and also plays good basketball so All tall people are good basket players is a biased conclusion.

Four hot air balloons each descend 295 feet per minute for 7 minutes. Find the total change in altitude for all 4 balloon
Answer: There is descending of 8260 feet in altitude for all 4 balloons.
Step-by-step explanation:
Since we have given that
Number of hot air balloons = 4
Number of minutes = 7 minutes
Descending per minute = 295
So, Total change in altitude for all 4 balloons is given by
[tex]295\times 7\times 4\\\\=8260\ feet[/tex]
Hence, there is descending of 8260 feet in altitude for all 4 balloons.
The total change in altitude for all 4 balloons will be 8260 feet
Number of minutes used per balloon = 7 minutesNumber of balloons = 4Number of feet when descending = 295
The total change in altitude for all 4 balloons will be calculated thus:
= 295 feet × 4 × 7
= 8260 feet
Therefore, the total change of the four balloons is 8260 feet.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the number of ounces of orange juices be A
Now , the amount spent on orange juice = $ 3.42
The cost per ounce of juice = $ 0.12
So , the number of ounces A = amount spent on orange juice / cost per ounce of juice
On simplifying the equation , we get
The number of ounces A = 3.42 / 0.12
The number of ounces A = 28.5 ounces
Hence , the equation is A = 28.5 ounces

A nonlinear function that can be written on the standard form
ax2+bx+c,wherea≠0ax2+bx+c,wherea≠0is called a quadratic function.
All quadratic functions has a U-shaped graph called a parabola. The parent quadratic function is
y=x2y=x2The lowest or the highest point on a parabola is called the vertex. The vertex has the x-coordinate
x=−b2ax=−b2aThe y-coordinate of the vertex is the maximum or minimum value of the function.
a > 0 parabola opens up minimum value
a < 0 parabola opens down maximum value
A rule of thumb reminds us that when we have a positive symbol before x2we get a happy expression on the graph and a negative symbol renders a sad expression.
The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry. The axis of symmetry has the equation
x=−b2ax=−b2aThe y-intercept of the equation is c.
When you want to graph a quadratic function you begin by making a table of values for some values of your function and then plot those values in a coordinate plane and draw a smooth curve through the points.

In the given figure since W is the midpoint of ZY, therefore, the measure of arc ZV and arc VY will be equal; and ZX and XY will be equal. Also, it is given that the measure of arc ZV is 43°. Therefore, we can write,
mZV + mVY + mXY + mXZ = 360°
43° + 43° + mXY + mXY = 360°
2(mXY) = 360° - 43° - 43°
mXY = 274/2
mXY = 137°
Hence, the measure of arc XY is 137°.
