Lily owns a spunky German Sheppard named Max. Max went viral last year when she posted a meme of him known as “Max the Boss Dog”. Lily thought it would be a great idea to license the meme. Now every time the meme is shared, she receives $0.16 in royalties. If the Max meme was shared 88 times last week, how much money did Lily earn in royalties?
Answers
Earnings = Number of shares * Royalty amount per share
Earnings = 88 * $0.16
Earnings = $14.08

O Fewer tickets were sold on the fourth day than on the tenth day.
O More tickets were sold on the fourth day than on the tenth day
Save and Exit
Answers
Answer:
The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
average rate of change from d = 4 to d = 10 is
(T(10) - T(4))/(10 - 4)
If the average rate of change is 0, then
(T(10) - T(4))/(10 - 4) = 0
T(10) - T(4) = 0 * 6
T(10) - T(4) = 0
T(10) = T(4)
That means the same number of tickets were sold on days 4 and 10.
Answer: The same number of tickets was sold on the fourth day and tenth day.

What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The functions are given as

Rewrite the equation in vertex form and identify the vertex, the axis of symmetry, and the y-intercept. y=-2x^2+12x-26
Answers
Answer:
The equation of the polynomial in vertex form is \(y +8= (-2)\cdot (x-3)^{2}\), its vertex is \((h,k) = (3, -8)\).
The expression of the axis of symmetry is \(x = 3\).
The y-intercept of the function is -26.
Step-by-step explanation:
The vertex form of the second order polynomial is defined by the following expression:
\(y-k = C\cdot (x-h)^{2}\) (1)
Where:
\(x\) - Independent variable, dimensionless.
\(y\) - Dependent variable, dimensionless.
\(h,k\) - Coordinates of the vertex, dimensionless.
\(C\) - Vertex constant, dimensionless.
Let \(y = -2\cdot x^{2}+12\cdot x - 26\), then we proceed to present the produre for the determination of the vertex form:
1) \(y = -2\cdot x^{2}+12\cdot x - 26\) Given
2) \(y = (-1)\cdot (2\cdot x^{2})+(-1)\cdot (-12\cdot x) + (-1)\cdot (26)\) \((-a)\cdot (-b) = a\cdot b\)/\((-a)\cdot b = -a\cdot b\)
3) \(y = (-1)\cdot (2\cdot x^{2}-12\cdot x +26)\) Distributive property
4) \(y = [(-1)\cdot (2)]\cdot (x^{2}-6\cdot x +13)\) Associative and distributive properties
5) \(y = (-2)\cdot [(x^{2}-6\cdot x+9)+4]\) \((-a)\cdot b = -a\cdot b\)
6) \(y = (-2) \cdot [(x-3)^{2}+4]\) Perfect square trinomial
7) \(y = (-2)\cdot (x-3)^{2}+4\cdot (-2)\) Distributive property
8) \(y = (-2)\cdot (x-3)^{2}+(-8)\) \((-a)\cdot b = -a\cdot b\)
9) \(y +8= (-2)\cdot (x-3)^{2}\) Compatibility of addition/Existence of the additive inverse/Modulative property/Result.
The equation of the polynomial in vertex form is \(y +8= (-2)\cdot (x-3)^{2}\), its vertex is \((h,k) = (3, -8)\).
The axis of symmetry is a line perpendicular to axis in which the square component of the vertex form is set. The expression of the axis of symmetry is \(x = 3\).
The y-intercept is the value of the polynomial when \(x = 0\), then, the value is:
\(y = -2\cdot (0)^{2}+12\cdot (0) -26\)
\(y = -26\)
The y-intercept of the function is -26.

which grows at the fastest rate for increasing values of x
\(f(x)=4*2^x\\h(x)=9x^2+25\\\\g(x)=15x+6\)
Answers
The function that grows at the fastest rate for increasing values of x is f(x) = 4×2ˣ.
We can see this by comparing the growth rates of the three functions for larger and larger values of x.
As x gets larger, the exponential function f(x) grows much faster than the other two functions, which are both polynomial functions.
if we plug in x = 10, we get:
f(10) = 4×2¹⁰ = 4×1024 = 4096
h(10) = 9×10² + 25 = 925
g(10) = 15×10 + 6 = 156
As we can see, f(10) is much larger than h(10) and g(10), indicating that f(x) grows at a much faster rate than the other two functions.

For the function f(x) = 2x + 3 the third iterate x₃ is 37
To find the third iterate, x3, of the function f(x) = 2x + 3, given an initial value of x₀ = 2,
we can apply the function repeatedly.
Starting with x₀ = 2:
x₁ = f(x₀)
= 2(2) + 3
= 7
x₂ = f(x₁)
= 2(7) + 3 = 17
x₃ = f(x₂)

Find the measure of the marked angles

Answers
The measure of the angles are (4x + 24)° = 52° and (6x - 10)° = 32°; The value of x =7°.
What is vertically opposite angles?
The opposing angles created by the junction of two lines are known as vertical angles or vertically opposite angles. A pair of angles that are vertically opposed to one another are always equal.Vertically opposite angles, or ical angles. A pair of angles that are vertically opposed to one another are always equal. Additionally, a vertical angle and the angle to which it is adjacent are supplementary angles, meaning their sum is 180 degrees.Two lines are said to intersect when they cross at a certain location in a plane. The lines are referred to as parallel when they do not intersect at any point in the plane.So, (4x + 24)° = (6x - 10)°
24° - 10° = 6x - 4x
2x = 14°
x = 14°/2
x = 7°
Substitute x in those values:
(4x + 24) = (4(7) + 24)°
= 28+24
= 52°
(6x - 10)° = (6(7) -10)
= 42° - 10°
= 32°
Hence, the measure of the angles are (4x + 24)° = 52° and (6x - 10)° = 32°; The value of x =7°.

The exponential function that passes through the point (-1, 1/7) for the given interval is f(x) = 7ˣ.
What is the exponential function?To find the exponential function that passes through the points (-1, 1/7), we can use the general form of an exponential function, which is:
f(x) = aˣ
where;
a is the base of the exponential function.First, we can use the given point (-1, 1/7) to find the value of "a". Substituting these values into the equation, we get:
1/7 = a⁻¹
To solve for "a", we can take the reciprocal of both sides of the equation and simplify:

In the image attached below, segment LK is a midsegment of the triangle which is parallel to a third side, segment HJ.
Therefore:
LK = 1/2(HJ) [triangle midsegment theorem]

An organization advocating for healthcare reform has estimated the average cost of providing healthcare for a senior citizen receiving Medicare to be about $13,000 per year. The article also stated that, with 90% confidence, the margin or error for the estimate is $1,000. Determine the resulting 90% confidence interval for the average cost for healthcare of a senior citizen receiving Medicare.
Answers
Using the definition of a confidence interval, it is found that the 90% confidence interval for the average cost for healthcare of a senior citizen receiving Medicare is ($12,000, $14,000).
A confidence interval is the sample mean plus/minus the margin of error.
In this problem, the sample mean is of $13,000.The margin of error is of $1,000.Hence:
$13,000 - $1,000 = $13,000
$13,000 + $1,000 = $14,000

The solution for the system of equation is (8, 1), Hence the correct option is c.
Describe the solution to this system of equations?The given system of equations is:
–3x + 2y = –22
–5y = –4x + 27
We can solve for x and y using elimination method:
–3x + 2y = –22
⇒ -3x + 2y = -22
–5y = –4x + 27
⇒ –4x + –5y = - 27
Eliminate x,
-3x + 2y = -22
-4x - 5y = -27
That is
-12x + 8y = -88
-12x - 15y = −81
0 −7y = −7
or
-7y = -7
y = 7/7
y = 1
Solve for x by substituting the value of y in –3x + 2y = –22
–3x + 2(1) = –22
–3x + 2 = –22
–3x = –22 - 2
–3x = −24
x = 24/3

Work out (7 x 10^5) ÷ (2 × 10²)
Give your answer in standard form.
Answers
Answer:
\(3.5 x 10^6\)
Step-by-step explanation:
To work out (7 x 10^5) ÷ (2 × 10²) and give the answer in standard form, we need to simplify the expression and express the result in the form a × 10^n, where 1 ≤ a < 10.
First, we can simplify the expression by dividing 7 by 2 and subtracting the exponents of 10:
(7 x 10^5) ÷ (2 × 10²) = (7/2) x 10^(5-2) = 3.5 x 10^3
Next, we can express the result in standard form by moving the decimal point to the right until we have a number between 1 and 10, and adjusting the exponent accordingly:
3.5 x 10^3 = 3.5 x 10^(3+3) = 3.5 x 10^6
Therefore, (7 x 10^5) ÷ (2 × 10²) in standard form is 3.5 x 10^6.
