Write an algebraic equation for the following. The product of three and a squared number is twice the sum of the number and four.
Use the remainder theorem to determine the remainder when d4 + 2d2 + 5d − 10 is divided by d + 4.
The remainder theorem states that the answer when d + 4 is substituted into the whole equation, the remainder would be the answer divided by d + 4. Therefore:
d + 4 = 0
d = -4
Evaluating when d = -4:
d^4 + 2 * d^2 + 5 * d − 10
= (- 4)^4 + 2 * (- 4)^2 + 5 * (- 4) – 10
= 256 + 2 * 16 – 20 – 10
= 256 + 32 – 30
= 258
Therefore basing on the remainder theorem, the remainder would then be:
Remainder = 258 / (d + 4) ---> Answer

The point $(r,\theta)$ in polar coordinates is $(7,5)$ in rectangular coordinates. what is the point $\left( 2r, \theta + \frac{\pi}{2} \right)$ in rectangular coordinates?
Final Answer:
The rectangular coordinates of the point[tex]$\left( 2r, \theta + \frac{\pi}{2} \right)$[/tex], where [tex]$(r, \theta)$[/tex] corresponds to the polar coordinates (7, 5), are approximately (-13.59, 11.54).
Step-by-step explanation:
In polar coordinates, a point is represented as [tex]$(r, \theta)$[/tex] , where [tex]$r$[/tex] is the distance from the origin, and $\theta$ is the angle with respect to the positive x-axis. In rectangular coordinates, the point is represented as (x, y).
Given that the point [tex]$(r, \theta)$[/tex] in polar coordinates is equivalent to the point (7, 5) in rectangular coordinates, we can express this relationship as:
[tex]\[ x = r \cos(\theta) \][/tex]
[tex]\[ y = r \sin(\theta) \][/tex]
For the given point $(7, 5)$, we have:
[tex]\[ x = 7 \cos(5) \][/tex]
[tex]\[ y = 7 \sin(5) \][/tex]
Now, you want to find the point [tex]$\left( 2r, \theta + \frac{\pi}{2} \right)$[/tex] in rectangular coordinates. This can be expressed as:
[tex]\[ x' = 2r \cos\left(\theta + \frac{\pi}{2}\right) \][/tex]
[tex]\[ y' = 2r \sin\left(\theta + \frac{\pi}{2}\right) \][/tex]
We know that [tex]$\cos\left(\theta + \frac{\pi}{2}\right) = -\sin(\theta)$[/tex] and [tex]$\sin\left(\theta + \frac{\pi}{2}\right) = \cos(\theta)$[/tex]. Substituting these into the equations:
[tex]\[ x' = -2r \sin(\theta) \][/tex]
[tex]\[ y' = 2r \cos(\theta) \][/tex]
Now, if we substitute the values of [tex]$r$[/tex] and [tex]$\theta$[/tex] from the given point (7, 5):
[tex]\[ x' = -2 \times 7 \times \sin(5) \][/tex]
[tex]\[ y' = 2 \times 7 \times \cos(5) \][/tex]
Calculating these values will give you the rectangular coordinates of the point $\left( 2r, \theta + \frac{\pi}{2} \right)$.

If triangle CDF ∼ triangle MKP, what is the value of x?
0.2
1.6
4.8
5.4
Answer:
The value of x is 1.6
Step-by-step explanation:
We have been given that triangle CDF ∼ triangle MKP.
Therefore, the ratio of the corresponding sides are equal.
Hence, we have
[tex]\frac{DC}{MK}=\frac{CF}{MP}[/tex]
Plugging the known values, we get
[tex]\frac{9}{1.8}=\frac{8}{0.x}[/tex]
Cross multiplying, we get
[tex]9x=8\times1.8[/tex]
Divide both sides by 9
[tex]x=\frac{8\times1.8}{9}[/tex]

The depreciating value of a semi-truck can be modeled by y = Ao(0.83)x, where y is the remaining value of the semi, x is the time in years, and it depreciates at 17% per year.
An exponential function comes down from the positive infinity and passes through the points zero comma seventy thousand. The graph is approaching the x-axis. What is the value of the truck initially, Ao, and how would the graph change if the initial value was only $50,000?
$70,000, and the graph would have a y-intercept at 50,000
$60,000, and the graph would have a y-intercept at 70,000
$70,000, and the graph would fall at a slower rate to the right
$70,000, and the graph would fall at a faster rate to the right
Answer:
Option A is correct.
Step-by-step explanation:
We are given that, the model for the depreciating value of a semi-truck is,
[tex]y = A_{O}(0.83)^x[/tex]
1. It is required to find the value of the truck initially i.e. when x= 0.
So, substituting x= 0, we have,
[tex]y = A_{O}(0.83)^0[/tex]
i.e. [tex]y = A_{O}\times 1[/tex]
i.e. [tex]y = A_{O}[/tex]
Since, the graph passes through the point (0,70,000).
Thus, we get, [tex]A_{O}=70,000[/tex]
Hence, the initial value is 70,000.
2. It is required to find the value of the truck initially i.e. when x= 50,000
That is, when x= 0, the value of y= 50,000.
Graphically, it means that the graph would cut y-axis at the point (0,50,000).
Thus, the y-intercept would be at 50,000.
Change in the initial value will not have any affect on the rate of the graph.
So, from the above, we get,
Option A is correct.

There are 9 different positions on a baseball team. if a team has 18 players how many different line-ups can the team make?
Final answer:
To find the number of different line-ups a team can make, we use permutations. Using the formula for permutations, we arrive at the answer of 437,760 different line-ups.
Explanation:
To find the number of different line-ups a team can make, we need to use the concept of permutations. Since there are 9 positions on a baseball team and 18 players, we can arrange the players in a line-up using the formula for permutations:
P(n, r) = n! / (n-r)!
Where n is the total number of players (18) and r is the number of positions (9). Substituting the values, we get:
P(18, 9) = 18! / (18-9)! = 18!/9! = 437,760.
Therefore, there are 437,760 different line-ups that the team can make.

If f(x) = –x2 + 3x + 5 and g(x) = x2 + 2x, which graph shows the graph of (f + g)(x)?
Answer:
Given the functions: [tex]f(x)= -x^2 +3x+5[/tex] and [tex]g(x) = x^2+2x[/tex]
Now, calculate first [tex](f+g)(x)[/tex] ;
[tex](f+g)(x) = f(x) + g(x)[/tex]
Substitute the given values we have;
[tex](f+g)(x) = -x^2+3x+5+x^2+2x[/tex]
Combine like terms;
[tex](f+g)(x) =5x+5[/tex]
Let y = [tex](f+g)(x)[/tex]
Then, we have y = 5x+5
Now, Graph the equation of the line y =5x +5
Using slope intercept form: An equation of line is given by :
y = mx +b ; where m is the slope of the line and b is the y-intercept.
On comparing we get;
m = 5 (Since, slope is positive which means a line moves upward on a graph from left to right)
Now, find the intercepts of the equation: y=5x+5;
x-intercepts: The graph or line crosses the x-axis i.,e
Substitute y = 0 and solve for x;
0 = 5x +5
Subtract 5 on both sides we get;
-5 = 5x
Divide both sides by 5 we get;
x = -1
x-intercepts= = (-1, 0)
Similarly for y-intercept:
Substitute the value of x= 0 and solve for y;
y = 5(0)+5
y = 5
y-intercepts = (0, 5)
Now, using these point we can draw a graph of function [tex](f+g)(x) =5x+5[/tex] as shown below in the attachment.

In scientific notation, 0.00001 is equal to 1 × 10⁻⁵.
FURTHER EXPLANATIONScientific notation is a way of expressing very big or very small numbers conveniently and with the appropriate number of significant figures. The general expression for the scientific notation is shown below:
M × 10ⁿ
M is a number that is greater than or equal to 1 but less than 10 and n is the number of times you have to multiply M by 10 to get the number.
The value of n can be easily determined by looking at the decimal point and counting the number of times it is moved to the left or to the right until a proper value of M is obtained.
The steps are as follows:
Locate the decimal point in the given. If it's a whole number, there is an implied decimal point at the end or to the right of the last digit.Move the decimal point to the right or to the left until you get a number that is greater than or equal to 1 but less than 10. This will be the value of M.Count how many decimal places you moved through to get the value of M. This will be the numerical value of the exponent, n.NOTE: If the decimal point was moved to the left, then the
exponent n will be written as positive (+x).
If the decimal point was moved to the right, then the
exponent n will be written as negative (-x).
Applying the steps to the problem:
STEP 1: 0.00001
The decimal point is four places away from the digit 1.
STEP 2: To get a number M that is greater than or equal to 1 but less than 10, the decimal point must be moved five places to the right and placed after the digit 1. (000001 or 1)
STEP 3: Since the decimal point was moved five places to the right, the exponent should have a magnitude of 5 and a negative sign. (1 × 10⁻⁵)
