Consider the function f(x) = 10(x2 – 7x). what are the additive and multiplicative inverses?
Answer:
Additive = -10x^2+70x
Multiplicative = 1/10x(x−7)
Step-by-step explanation:
The multiplicative inverse of a number is the reciprocal of that number. Since 10(x^2−7x)⋅ 1/10x(x−7)=1 , then 1/10x(x−7) is the multiplicative inverse of 10(x^2−7x) .
Since 10(x^2−7x)−10x^2+70x=0 , then −10x^2+70x
is the additive inverse of 10(x^2−7x).

In a video game, two objects move around the screen according to the equations r = 4cos(θ) and r = –1 2cos(θ). which coordinates represent a possible collision point of the objects?
The coordinates represents a possible collision point of the objects according to equations r = 4cos(θ) and r = –1/ 2cos(θ) cos(∅) are (-2,2π/3).
Given Equations r = 4cos(θ) and r = –1 2cos(θ).
We have to find the coordinates of collision.
The first object is moving around the screen r = 4cos(θ).
The second object is moving around the screen r = –1 /2cos(θ).
According to question
Coordinate can be found out by equating both the equations.
4cos(θ) =–1 /2cos(θ)
2cos(θ)=-1
cos(θ)=-1/2
θ=[tex]cos^{-1} (1/2)[/tex]
=120°
θ=-2π/3
Therefore the two equations are equal when
θ=2π/3
we have
r=4 cos(2π/3)=-2
and r=-1+2 cos(2π/3)
r=-2
Hence the coordinates that represent the collision point are (-2,2π/3).

For each of the transformed square root functions, state the transformations and use them to plot the
transformed function on the same graph with the parent function.
Step-by-step explanation:
so, if I understand this correctly, the original function (shown in the graph) is
f(x) = sqrt(x)
the following transformations were done going from f(x) to h(x) :
x -> x + 4 as variable term moved the whole curve 4 units to the left. because now a specific functional value is calculated for a smaller x (by 4 units) than for the original f(x). e. g. let's call g(x) = sqrt(x + 4). then g(-4) = f(0). as mentioned, everything moved over to the left by 4 units.
sqrt(x) -> 3×sqrt(x) increased the range of the function (the generated y values) by the factor 3. was the functional result for a x value = 1, then it is now 3 for the same x value.
sqrt(x) -> sqrt(x) - 1 moved the whole curve down by 1 unit.
in summary, the whole original curve was moved 4 units to the left, then stretched upwards by the factor 3, and then that result was moved down by 1 unit.
so, e.g.
h(-4) = 3×f(0) - 1 = -1 point (-4, -1) corresponds to old (0, 0)
h(-3) = 3×f(1) - 1 = 2 point (-3, 2) corresponds to old (1, 1)
h(0) = 3×f(4) - 1 = 5 point (0, 5) corresponds to old (4, 2)

Please help!!! Select the quadratic equation that has no real solution.
Answer:
[tex]25x^2-10x+4[/tex]
Step-by-step explanation:
You can use the quadratic formula to determine if a quadratic equation has real or imaginary solutions. The quadratic formula is: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]. What really matters in this case is the discriminant, which is the stuff under the radical which is: [tex]b^2-4ac[/tex]. This is because the solutions are only imaginary, if the discriminant is negative, because then you would be taking the square root of a negative number. So let's look through each example:
[tex]25x^2+20x-4[/tex]; a=25, b=20, c-4: [tex]20^2-4(25)(-4) = 800[/tex]. By examining this one example, it's important to note, if you have one negative number as a or c, then it cancels out the negative sign in the -4, and it becomes positive. So let's look at examples where a or c doesn't equal a negative number OR both a and c equal negative, that way they cancel out and over -4ac is still negative.
[tex]25x^2-10x+4[/tex]; a=25, b=-10, c=4. In this case both a and c are positive so -4ac will remain negative. This gives you: [tex](-10)^2-4(25)(4) = 100-400 = -300[/tex]. So this has a negative discriminant meaning it will have no real solution but rather imaginary solutions

If the standard notation (original number) is 0.004430 cm, what would the sign of the exponent be?
Zero
Positive
Negative
Answer:
Negative
Step-by-step explanation:
When you move the decimal place to the right, the exponent in scientific notation is negative. In other words, when you are converting a number smaller than 1 into scientific notation, the exponent will be negative. In this case, because you are moving the decimal place to the right 3 places, the new number would be 4.430 x 10⁻³ cm.
When you move the decimal place to the left, the exponent in scientific notation is positive.
A cookware consultant sells two types of pizza stones. The circular(e) stone sells for $26 and the rectangular (r) one sells for $34. In one month she sold 37 stones. If she made a total of $1138 from the sale of the pizza stones, how many of each size did she sell?
Answer:
Step-by-step explanation:
Conditions
Let the circular stones = x
Let the rectangular stones = y
Equations
x + y = 37 Subtract x from both sides of this equation.
y = 37 - x Notice that x is on the right side of the equation
Solution
26x + 34y = 1138 Substitute for y
26x + 34(37 - x) = 1138 Remove the brackets
26x + 1258 -34x= 1138 Combine
-8x + 1258 = 1138 Subtract 1258 from both sides
-8x +1258-1258 = 1138-1258 Combine.
-8x = -120 Divide both sides by -8
-8x/-8 = -120/-8
x = 15 Two minuses make a plus (last step)
x+ y = 37
15 + y = 37 Subtract 15 from both sides
15-15 +y = 37-15 Combine
y = 22
Answer
x = 15 Circular pizza dishes
y = 22 square pizza dishes
The consultant sold 15 circular pizza stones and 22 rectangular pizza stones.
How to determine how many of each size did she sell?Let's assume the number of circular pizza stones sold is "c" and the number of rectangular pizza stones sold is "r."
We are given two pieces of information:
1. The total number of stones sold: c + r = 37
2. The total amount earned from the sale of the stones: 26c + 34r = 1138
Now, we can use these two equations to solve for the values of "c" and "r."
First, let's use the first equation to express "c" in terms of "r":
c = 37 - r
Now, substitute this value of "c" into the second equation:
26c + 34r = 1138
26(37 - r) + 34r = 1138
962 - 26r + 34r = 1138
Combine the "r" terms:
8r = 1138 - 962
8r = 176
Now, divide by 8 to find the value of "r":
r = 176 / 8
r = 22
Now that we have the value of "r," we can find the value of "c" using the first equation:
c = 37 - r
c = 37 - 22
c = 15
So, the consultant sold 15 circular pizza stones and 22 rectangular pizza stones.

Suppose that f(n)=f(n/5)+3n when n is a positive integer divisible by 5, and f(1)=4.
By means of recurrence formulas and a given initial value, we find the following three results: f(5) = 19, f(125) = 469, f(3125) = 11719.
How to find the value the elements of a sequence by recurrence formula
Sequences are sets of values defined by at least one condition. In this case, we have three conditions to generate the required values:
f(n) = f(n/5) + 3 · n
f(1) = 4
[tex]n \in \mathbb{N}[/tex]
Now we proceed to find the elements by recurrence:
f(5) = f(1) + 3 · 5
f(5) = 4 + 15
f(5) = 19
f(25) = f(5) + 3 · 25
f(25) = 19 + 75
f(25) = 94
f(125) = f(25) + 3 · 125
f(125) = 94 + 375
f(125) = 469
f(625) = f(125) + 3 · 625
f(625) = 469 + 3 · 625
f(625) = 469 + 1875
f(625) = 2344
f(3125) = f(625) + 3 · 3125
f(3125) = 2344 + 9375
f(3125) = 11719
By means of recurrence formulas and a given initial value, we find the following three results: f(5) = 19, f(125) = 469, f(3125) = 11719.

Factor completely x^8- 16.
Answer:
Step-by-step explanation:
So in this example we'll be using the difference of squares which essentially states that: [tex](a-b)(a+b)=a^2-b^2[/tex] or another way to think of it would be: [tex]a-b=(\sqrt{a}-\sqrt{b})(\sqrt{a}+\sqrt{b})[/tex]. So in this example you'll notice both terms are perfect squares. in fact x^n is a perfect square as long as n is even. This is because if it's even it can be split into two groups evenly for example, in this case we have x^8. so the square root is x^4 because you can split this up into (x * x * x * x) * (x * x * x * x) = x^8. Two groups with equal value multiplying to get x^8, that's what the square root is. So using these we can rewrite the equation as:
[tex]x^8-16 = (x^4-4)(x^4+4)[/tex]
Now in this case you'll notice the degree is still even (it's 4) and the 4 is also a perfect square, and it's a difference of squares in one of the factors, so it can further be rewritten:
[tex]x^4-4 = (x^2-2)(x^2+2)[/tex]
So completely factored form is: [tex](x^2-2)(x^2+4)(x^4+4)[/tex]
I'm assuming that's considered completely factored but you can technically factor it further. While the identity difference of squares technically only applies to difference of squares, it can also be used on the sum of squares, but you need to use imaginary numbers. Because [tex]x^2+4 = x^2-(-4)[/tex]. and in this case a=x^2 and b=-4. So rewriting it as the difference of squares becomes: [tex]x^4+4 = x^4 - (-4) = (x^2-\sqrt{-4})(x^2+\sqrt{-4}) = (x^2-2i)(x^2+2i)[/tex] just something that might be useful in some cases.
We can factor this into [tex](x^{4}+4)(x^{4} -4)[/tex].
This is because we use difference of two squares where [tex]x^{2} -y^{2} = (x+y)(x-y)[/tex]
So we rewrite x^8-16 to x^8-4^2.
This can then be written to the equation I put at the start.
p.s. The reason its [tex]x^{4}[/tex] is because [tex]x^{4} * x^{4} = x^{8}[/tex]

The first four terms in the sequence are 4, 9, 16 and 25.
Given that, the nth term of the sequence is 1 (n + 1)².
We need to find the first four terms in the sequence.
What is the sequence?In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
To find the first four terms of the sequence, replace n=1, 2, 3 and 4.
Now, when n=1
1(1+1)²=1×4=4
When n=2
1(1+2)²=1×9=9
When n=3
1(1+3)²=1×16=16
When n=4
1(1+4)²=1×25=25
Therefore, the first four terms in the sequence are 4, 9, 16 and 25.
