Answer: The correct option is (B) 258.
Step-by-step explanation: We are give to use the remainder theorem to determine the remainder when
[tex]d^4+2d^2+5d-10[/tex] is divided by [tex]d+4.[/tex]
Remainder Theorem : If p(x) is a polynomial in x and a is any real number, then the remainder when p(x) is divided by (x - a) is p(a).
For the given division, we have

Billy Goats invested some money in stocks and bonds. The total amount he invested was $\$165,\!000$. If he invested 4.5 times as much in stocks as he did in bonds, what was his total investment in stocks?
An equation is formed when two equal expressions. The total investment that Billy made in stocks is $135,000.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the amount that is invested in stocks be represented by x, while the amount that is been invested in bonds is represented by y.
Given that Bily invested 4.5 times as much in stocks as he did in bonds. Therefore, the equation to represent the given situation can be written as,
x = 4.5y
Also, given that the total amount that Billy invested is $165,000. Therefore, the total invested amount can be written as,
$165,000 = x + y
Substitute the value of x in the equation,
$165,000 = 4.5y + y
$165,000 = 5.5y
y = $165,000 / 5.5
y = $30,000
Now substitute the value of y in the first equation to know Billy's investment in stocks.
x = 4.5y
x = 4.5($30,000)
x = $135,000
Hence, the total investment that Billy made in stocks is $135,000.

The mean diastolic blood pressure for a random sample of 70 people was 94 millimeters of mercury. if the standard deviation of individual blood pressure readings is known to be 12 millimeters of mercury, find a 90% confidence interval for the true mean diastolic blood pressure of all people.
To solve this problem, we make use of the formula for Confidence Interval:
Confidence Interval = X ± z * σ / sqrt (n)
where X is the mean value, z is the z score which is taken from the standard tables, σ is the standard deviation, and n is the number of samples
z = 1.645 (at 90% Confidence Level)
Substituting the values into the equation:
Confidence Interval = 94 ± 1.645 * 12 / sqrt (70)
Confidence Interval = 94 ± 2.36
Confidence Interval = 91.64, 96.36
Therefore at 90% confidence level, the blood pressure reading ranges from 91.64 mmHg to 96.36 mmHg.

Determine the width of the garden. Nina must put 60 feet of fencing around her rectangular garden. The length of the garden is three feet longer than twice the width. What is the solution set for 2w + 2(2w + 3) = 60 given the replacement set {6, 7, 8, 9}?
2w+2(2w+3)=60
2w+4w+6=60
6w+6=60
6w=54
w=54/6 =9
the width is 9 feet
Answer:
9 is a solution.
Step-by-step explanation:
The replacement set is the set of values that can be substituted in the equation (for the variables).
Given a replacement set, we need to substitute every value of the set in our equation and see if the equation holds for that value. If it does, then the value is a solution of the equation.
In this problem we have the equation 2w + 2(2w + 3) = 60 and the replacement set is {6,7,8,9}
We are going to start replacing the different values of the set.
w = 6[tex]2w + 2(2w + 3) = 60\\2(6) + 2(2(6)+3) = 60\\12 + 2(12+3) = 60\\12 + 2(15) = 60\\12 + 30 \neq 60[/tex]
Thus, 6 is not a solution.
w = 7[tex]2w + 2(2w + 3) = 60\\2(7) + 2(2(7) +3) = 60\\14 + 2 (14+3) =60\\14 + 2(17)=60\\14+34=60\\48 \neq 60[/tex]
Thus, 7 is not a solution.
w = 8[tex]2w + 2(2w + 3) = 60\\2(8) + 2(2(8)+3) = 60\\16 + 2(16+3)=60\\16 +2 (19) =60\\16 + 38 \neq 54[/tex]
Thus, 8 is not solution.
w = 9[tex]2w + 2(2w + 3) = 60\\2(9) + 2(2(9) + 3) =60\\18 + 2 (18+3) =60\\18 +2(21)=60\\60=60[/tex]
Thus, 9 is a solution.
In what direction and by how many units is the graph of f(x) = 6 sin(2x + π) − 5 vertically and horizontally shifted?
Down 5, left pi over 2
Up 5, left pi over 2
Down 5, right pi over 2
Up 5, right pi over 2
Answer:
Option 1 is correct.
Step-by-step explanation:
Given graph of f(x)=6 sin(2x + π) - 5
we have to tell in what direction the graph vertically and horizontally shifted.
As, f(x+1) is a change on the inside of function, giving a horizontal shift left by 1, and the subtraction by 3 in f(x+1)-3 is a change to the outside of function, giving a vertical shift down by 3.
Hence, the graph of f(x)=6sin(2x + π) - 5
Here, change on the inside of function, giving a horizontal shift left by [tex]\frac{\pi}{2}[/tex], and subtraction by 5 in function is a change to the outside of function, giving a vertical shift down by 5.

what is the quotient? x-3 divided into 4x2+3x+2
The quotient of x-3 divided into 4x^2+3x+2 is 4x+9.
Explanation:To find the quotient of x-3 divided into 4x^2+3x+2, we need to perform polynomial long division.
Divide the first term of the numerator (4x^2) by the first term of the denominator (x) to get 4x. Write this as the first term of the quotient.Multiply the entire denominator (x-3) by the quotient term (4x) and subtract it from the numerator (4x^2+3x+2).Bring down the next term from the numerator (-3x).Repeat steps 1 and 2 with the new numerator (-3x) and the denominator (x-3).Continue this process until there are no more terms to bring down and divide.After performing polynomial long division, the quotient is 4x+9.
Final answer:
To find the quotient of x-3 divided into 4x^2+3x+2, you can use long division. The quotient is 4+15 with a remainder of 47.
Explanation:
To find the quotient of x-3 divided into 4x2+3x+2, we can use long division.
First, divide the 4x2 term by the x term, which gives us 4x.Multiply 4x by x-3 to get 4x2-12x.Subtract 4x2-12x from 4x2+3x+2 to get 15x+2.Now, divide 15x by x to get 15.Multiply 15 by x-3 to get 15x-45.Subtract 15x-45 from 15x+2 to get 47.Since there are no more terms to divide, the quotient is 4+15 and the remainder is 47.Therefore, the quotient of x-3 divided into 4x2+3x+2 is 4+15 with a remainder of 47.
