Given f(x) = x³ + kx + 3, and x + 3 is a factor of f(x), then what is the value of
k?
If (x + 3) is a factor of f(x) = x³ + kx + 3 , then the value of k is -8 .
In the question ,
it is given that ,
the function is f(x) = x³ + kx + 3 ,
and also given that (x+3) is a factor of f(x) , that means
x + 3 = 0
x = -3
x = -3 should satisfy the function ,
So , substituting x = -3 in the function f(x) = x³ + kx + 3,
we get
f(-3) = (-3)³ + k(-3) + 3 = 0
-27 -3k + 3 = 0
-3k - 24 = 0
-3k = 24
k = 24/(-3)
k = -8
Therefore , If (x + 3) is a factor of f(x) = x³ + kx + 3 , then the value of k is -8 .

Answer:
Step-by-step explanation:
Hi, Julia, they are trying to ask about error, or the confidence that there is not an error. It's kinda like saying, we're 100% sure the answer is correct, mostly :DDDD which really lowers your confidence about the 100% correct statement. Anyway, sooo then they give the way to show deviation, from something. if you've had Calculus one, this is the same thing as the Delta , Epsilon thing, about a small distance away from the target is still with in a certain range. I feel like if they had written the inequality like this...
( p' - E) < p < (p'+E) it would be clearer about the inequality. E is just a tiny distance away in the positive and negative direction. E plays the role of epsilon. the numbers they give are the range of the confidence. I don't think they ask a very clear question.
0.056<p<0.112
p is kinda like our "best guess" answer, and we're giving it this range that it's probably within, for a certain level of confidence. You can see, that as the confidence goes down, that range can become bigger.

In ΔQRS, s = 7.9 cm, ∠Q=125° and ∠R=23°. Find the length of q, to the nearest 10th of a centimeter.
The length of q, to the nearest 10th of a centimeter, is 8.8 cm.
We are given the following;
In ΔQRS, s = 7.9 cm, ∠Q=125° and ∠R=23°.
The third angle can be calculated using the angle sum property:
angle Q + angle R + angle S = 180 degrees
125 degrees + 23 degrees + angle S = 180 degrees
angle S = 180 - (125 + 23) degrees
angle S = 180 - 148 degrees
angle S = 32 degrees
To find the length of q we shall apply the Sine rule.
q / Sin Q = s / Sin S
q / Sin 125 = 7.9 / Sin 32
by cross multiplication we will get;
q = (7.9 x Sin 125) / Sin 32
q = (7.9 x 0.61) / 0.55
q = 8.8 cm (approximately)
So, the length of q is 8.8 cm.
Thus, the length of q, to the nearest 10th of a centimeter, is 8.8 cm.

Kye's current credit card balance is $3,109.87 with a minimum payment of $159.00. Over the next month he spends $532.42. If the APR is 27.99% (billed monthly), what will Kye's new balance be, with interest?
Therefore , the solution of the given problem of interest comes out to be $4,088.14 is the new balance.
What exactly does interest mean?Divide the number by the expense of borrowing, the remaining time, and other factors to get the simple interest rate. In marketing, the straightforward return plan is principal interest payments plus hours. This technique is the simplest way to figure out interest. The most common way to determine income is as a percentage of the principal sum.
Here,
We must first figure out the interest on the present balance.
The interest rate is 27.99%/12, or 0.0233, per month.
As a result, the current balance's interest rate is:
=> 3,109.87 x 0.0233 = $72.43
When this interest is added to the outstanding amount, Kye's new balance is as follows:
=> 3,109.87 + 72.43 + 532.42 = $3,714.72
The minimum payment for the new amount must now be determined:
=> 3,714.72 x 0.02 = $74.29
Kye's minimum payment for the following month will be $159.00 because the minimum payment is the higher of $74.29 or that amount.
Kye's new balance with interest as a result of making the required minimum contribution and spending $532.42 is as follows:
=> 3,714.72 - 159.00 + 532.42 = $4,088.14.

Michael is working two summer jobs, making $19 per hour lifeguarding and making

must earn a minimum of $280. If a represents the number of hours lifeguarding and
y represents the number of hours clearing tables, write and solve a system of
inequalities graphically and determine one possible solution.
The possible solutions are 8 hours and 9 hours.
The number of hours for lifeguarding is 8 hours.
The number of hours for clearing tables is 9 hours.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Two summer jobs:
Lifeguarding.
x = number of hours
= $19 per hour
Cleaning tables.
y = number of hours
=$14 per hour
Total hours in a week = 17 hours
Minimum earning = $280
The inequality represents the above situation.
x + y ≥ 17
19x + 14y ≥ 280
Solving for x and y.
x + y = 17 _____(1)
x = 17 - y
19x + 14y = 280 ______(2)
Putting (1) in (2) we get,
19(17 - y) + 14y = 280
323 - 19y + 14y = 280
323 - 5y = 280
323 - 280 = 5y
43 = 5y
y = 43/5
y = 8.6
y = 9
Now,
x = 17 - y
x = 17 - 8.6
x = 8.4
x = 8

A truck travels 50 m/s in a 30 second time frame what is the average speed
The average speed of the truck is 50 m/s .
We know that the average speed of any vehicle is calculated by total distance divide by total time.
Now the truck travels at 50 m/s for 30 seconds.
Distance covered in 30 seconds = 50 × 30 = 1500 meters
Time taken = 30 seconds
average speed = 1500 / 30 = 50 m/s
The average speed now accounts for the majority of the distance travelled. Average speed is essentially a method for calculating distance and the rate of transit time.
Knowing the average speed is crucial because it is clear that the pace will vary throughout the voyage. The average speed of a vehicle or an object can be determined using a variety of methods.
That is the most popular and simple way for figuring your average speed. It functions best when the object's speed remains constant throughout the journey, never rising or falling.

The greatest width possible if the length of the rectangular lot is 25 ft longer than twice the width and if the perimeter of the lot cannot exceed 350 ft is 50 ft.
We are given,
The length of the rectangular lot is 25 ft longer than twice the width.
The perimeter of the lot cannot exceed 350 ft.
Let the width of the rectangular lot be x.
So, the length of the rectangular lot = 2x + 25
We know that the perimeter of the rectangle is given by:
P = 2(L + W)
Substitute the given values in the above formula;
350 = 2(2x +25 + x)
350 / 2 = 3x + 25
175 - 25 = 3x
x = 150 / 3
x = 50 ft
So, the width of the rectangular lot = 50 ft
And, the length of the rectangular lot = 2 * 50 + 25 = 125

What is the equation for the line that is perpendicular to y=−1/2x+5 and passes through the point (0, 7)?
The equation of line passes through the point (0, 7) will be;
⇒ y = 1/2x + 7
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (0, 7).
And, The perpendicular line is,
⇒ y = -1/2x + 5
Now,
Since, The equation of line passes through the point (0, 7).
So, We need to find the slope of the line.
Since, The product of slope of the perpendicular lines is - 1.
Hence, Slope of the perpendicular line is,
y = -1/2x + 5
m₁ = dy/dx = - 1/2
m₁ = - 1/2
So, The slope of the line,
m₂ = - (- 1/2)
= 1 / 2
Thus, The equation of line with slope 1/2 is,
⇒ y - 7 = 1/2 (x - 0)
⇒ y - 7 = 1/2 x
⇒ y = 1/2x + 7
Therefore, The equation of line passes through the point (0, 7) will be;

Range: [0,∞), {y|y ≥ 0}
Step-by-step explanation:
1. Find where the FUNCTION is DEFINED.
A function is a set of ordered pairs where each first element is paired with one, and only one, second element. No element in either pair is without a partner.
2. Find the DOMAIN: The set of all x-values that a function passes through. Also, it is the left coordinate in a coordinate pair.
3. The RANGE: the set of all y-values that a function passes through. Also, it is the right coordinate in a coordinate pair.
