Answer:
41.1
Step-by-step explanation:
The number will be cut off after the digit you are rounding off to.
Rewrite the number, but stop at the 0.
41.0
Now you need to decide if the 0 stays as 0 or if it goes up to 1.
When the next digit is from 5 to 9, the last digit you keep goes up 1. When the next digit is 0 through 4, the last digit you keep stays as it was.
Since the first digit that was dropped is a 7, the 0 goes up one unit to 1.
Answer: 41.1
Answer:
41.1
Step-by-step explanation:
If we are rounding at the 0, we have to look at the next digit, which is 7.
Since 7>=5, we will round up. Zero becomes a 1
41.073 becomes 41.1

1. In a certain company, 30 percent of the men and 20 percent of the women attend night school. If 40
percent of all employees are men, what percent of all the employees attend night school?
Answer: 24% of all employees attend night school.
Step-by-step explanation: If 40% of all employees are men and 30% of the men attend night school, we can multiply 0.40 by 0.30 to get the percentage of men who attend night school: 12% or 0.12. To find the number of women who attend night school, multiply 0.20 by 0.60(assuming percentage of men and women add up to 100%) to get 12%. Add 12% and 12% to get 24% of all employees attend night school.

Answer:
y = 3x - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 5)
m = [tex]\frac{5+1}{2-0}[/tex] = [tex]\frac{6}{2}[/tex] = 3
the line crosses the y-axis at (0, - 1) ⇒ c = - 1
y = 3x - 1 ← equation of the line
what is the area of a square with a diagonals of the length of 6?
Answer:
Area = 18
Step-by-step explanation:
We know that a square has side lengths of s
We can use the Pythagorean theorem to find s
a^2 + b^2 = c^2
We know that the hypotenuse or c = the length of the diagonal or 6
Substituting in what we know
s^2 + s^2 = 6^2
2s^2 = 36
Divide each side by 2
2s^2/2 = 36/2
s^2 = 18
Take the square root of each side
sqrt(s^2) = sqrt(18)
We only have to take the positive square root since it is a length
s = sqrt(9) sqrt(2)
s= 3sqrt(2)
The side length of the square is 3sqrt(2)
To find the area, we multiply the side by the side or s^2
s^2 = (3sqrt(2))^2
From above
s^2 = 18
How many complex zeros does the polynomial function have?
F(x)=2x^4 +5x^3 - x^2 +6x-1
Answer:
Two complex roots.
Step-by-step explanation:
F(x)=2x^4 +5x^3 - x^2 +6x-1
is a polynomial in x of degree 4.
Hence F(x) has 4 roots. There can be 0 or 2 or 4 complex roots to this polynomial since complex roots occur in conjugate pairs.
Use remainder theorem to find the roots of the polynomial.
F(0) = -1 and F(1) = 2+5-1+6-1 = 11>0
There is a change of sign in F from 0 to 1
Thus there is a real root between 0 and 1.
Similarly by trial and error let us find other real root.
F(-3) = -1 and F(-4) = 94
SInce there is a change of sign, from -4 to -3 there exists a real root between -3 and -4.
Other two roots are complex roots since no other place F changes its sign
Final answer:
The polynomial function has 4 complex zeros.
Explanation:
A polynomial function is a function of the form f(x) = a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where a_n, a_(n-1), ..., a_1, a_0 are constants and n is a non-negative integer. The number of complex zeros of a polynomial function is equal to its degree.
The given polynomial function is f(x) = 2x^4 + 5x^3 - x^2 + 6x - 1. The highest power of x in the function is 4, so the degree of the function is 4. Therefore, the function has 4 complex zeros.
A line passes through the point (8,7) and has a slope of negative 3/4 Write an equation in slope-intercept form for this line.
The slope-intercept form for the line that passes through the point (8,7) and has a slope of -3/4 is y = -3/4x + 13. We found this by substituting the given slope and point into the slope-intercept equation and solving for b, the y-intercept.
Explanation:We're working on a mathematics problem here that involves the slope-intercept form of a line, which is usually written as y = mx + b. Here, m represents the slope of the line and b is the y-intercept, the point where the line intercepts the y-axis.
To write an equation for this line, we're given that the line passes through the point (8,7) and has a slope (rise over run) of negative 3/4, a negative value indicating the line decreases as it moves to the right.
We can substitute the slope and the given point into the slope-intercept equation to solve for the y-intercept: 7=(-3/4)*8+b, this simplifies to: 7=-6+b, and finally b=7+6 which gives us 13.
Therefore, the slope-intercept equation for this line with a slope of -3/4 and passing through the point (8,7) is y = -3/4x + 13.

Final answer:
The equation of the line passing through the point (8,7) with a slope of negative 3/4 is y = -3/4x + 13 in slope-intercept form.
Explanation:
To write an equation for a line in slope-intercept form given a point and a slope, we use the formula y = mx + b, where m is the slope and b is the y-intercept. For a line that passes through the point (8,7) with a slope of negative 3/4, we first input the slope into the equation, getting y = -3/4x + b. We then substitute the x and y values from the point (8,7) into the equation and solve for b: 7 = -3/4(8) + b. This simplifies to 7 = -6 + b, and adding 6 to both sides gives us b = 13. Thus, the equation of the line in slope-intercept form is y = -3/4x + 13.
Which values of P and Q result in an equation with exactly one solution? 2x+Q=Px−31 Choose all answers that apply: Choose all answers that apply: A -Q=−31 and P=−2 B- Q=31 andP=2 C - Q=−31 and P=2 D - Q=-2Q=−2 and P=2
Answer:
Option A is correct
Values of P = -2 and Q = -31
Step-by-step explanation:
Given the equation: [tex]2x+Q= Px-31[/tex]
Now, we put the given values
A.
Q = -31 and P = -2
2x + (-31) = -2x - 31
2x - 31 = -2x -31
4x = -31 + 31
4x = 0
x = 0 [one solution]
B.
Q = 31 and P = 2
2x + Q = Px -31
2x + 31 = 2x -31
Subtract 2x from both sides we get
31 = -31 False.
C.
Q = -31 and P = 2
2x + (-31) = 2x - 31
2x - 31 = 2x - 31 [More than one solutions, for any x]
D.
Q = -2 and P = 2
2x + Q = Px -31
2x + (-2) = 2x -31
2x -2 = 2x -31
2x - 2x = -31 + 2
Combine like term;
0 = -29 False.
Therefore, the values of P and Q results in an equation with exactly one solution is; P = -2 and Q = -31

The equation below represents Function A and the graph represents Function B: Function A f(x) = 6x - 1 Function B graph of line going through ordered pairs 1, 4 and negative 1, negative 2 and negative 2, negative 5 Which equation best compares the slopes of the two functions?
Answer:
Slope of function A is 6 and slope of function B is 3. Slope of A is twice of slope of function B. The relationship between slopes is
[tex]\text{Slope of Function A}=2\times \text{Slope of Function B}[/tex]
Step-by-step explanation:
The function A is,
[tex]f(x)=6x-1[/tex]
It can be written as,
[tex]y=6x-1[/tex]
It is the slope intercept form like [tex]y=mx+c[/tex], where m is the slope. On comparing the function A with the slope intercept form, we get the value of slope of function A is 6.
[tex]m_{A}=6[/tex]
The graph of function B passing through the point (1,4), (-1,-2) and (-2,-5).
If a line passing through the points and , then the slope of line is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Choose any two points of function B. Let the function B is passing through the points (1,4) and (-1,-2).
[tex]m_{B}=\frac{-2-4}{-1-1}[/tex]
[tex]m_{B}=\frac{-6}{-2}[/tex]
[tex]m_{B}=3[/tex]
The slope of function B is 3.
Since slope of function A is 6 and the slope of function B is 3, so we can say that the slope of function A is twice of slope of function B.
[tex]\text{Slope of Function A}=2\times \text{Slope of Function B}[/tex]
The slope of Function A is 6 and the slope of Function B is 3. Therefore, the slopes of the two functions are not equal.
The equation representing Function A is f(x) = 6x - 1.
The graph representing Function B is a line passing through the ordered pairs (1, 4), (-1, -2), and (-2, -5).
To compare the slopes of the two functions, we can calculate the slope of each function and see if they are equal.
The slope of Function A is 6, and the slope of Function B can be found using the formula (y2 - y1)/(x2 - x1) by choosing any two pairs of ordered points.
For example, using (1, 4) and (-1, -2).
The slope of Function B is (4 - (-2))/(1 - (-1)) = 6/2 = 3.
Since the slope of Function A is 6 and the slope of Function B is 3, we can conclude that the slopes of the two functions are not equal.

Evaluate the following.
Click on "Not a real number" if applicable.
Answer:
1) [tex]\sqrt{-64}[/tex] is not a real number.
2) [tex]-\sqrt{25} =-5[/tex]
Step-by-step explanation:
1) The square root of a number is defined for real numbers if and only if the number under the square root sign is greater than or equal to zero.
This implies that [tex]\sqrt{-64}[/tex] is not a real number because [tex]-64\:<\:0[/tex]
2) [tex]-\sqrt{25} =-\sqrt{5^2} =-5[/tex].
The number under the square root sign is [tex]25[/tex], which is greater than zero. Note that the negative sign is not inside the square root sign, it is outside it.
The value √-64 is not a real number, and -√25 is a real number.
√-64 and -√25 involve taking the square root of negative numbers, which results in complex numbers because real numbers do not have square roots of negative values.
Let's evaluate both:
√-64:
The square root of -64 is denoted as √(-64). In the realm of complex numbers, it's represented as 8i, where 'i' stands for the imaginary unit. So, √-64 = 8i.
-√25:
The square root of 25 is 5, and when you add a negative sign in front of it, you get -5. So, -√25 = -5.
In summary, √-64 is not a real number, and it is equal to 8i in the realm of complex numbers, while -√25 is a real number and equal to -5.

180°-(90°+68°)=180°-158°=22°
6
180°-22°=158°
Answer:
22° and 158°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in the triangle from 180
∠5 = 180° - (90 + 68)° = 180° - 158° = 22°
∠5 and ∠ 6 form a straight angle, thus the angles are supplementary
∠6 = 180° - ∠5 = 180° - 22° = 158°
352 ft is ____ % of 2 mi; 2 mi is ____ % of 352 ft
Answer:
352 ft is 3.34% of mi ;
2 mi is 3000% of 352 ft
Step-by-step explanation:
To calculate : 352 ft is ___% of 2 mi and 2 mi is ___% of 352 ft.
We can calculate first:
352 is x% of 2 mi.
Solve for x;
Use conversion:
1 mi = 5280 ft
2 mi = 10560 ft
x% of 10560 ft means [tex]\frac{x}{100} \times 10560 = 105.60 x[/tex]
then, our equation become;
352 = 105.6 x
Divide both sides by 105.6 we get;
x = 3.333333...
or
x ≈3.34
Similarly, for
2 mi is y% of 352 ft
Solve for y;
2 mi = 10560 ft
y% of 352 = [tex]\frac{y}{100} \times 352 = 3.52y[/tex]
then;
10560 = 3.52 y
Divide both sides by 3.52 we get;
[tex]y = \frac{10560}{3.52}[/tex]
y = 3000
Therefore; 352 ft is 3.34% of mi ; 2 mi is 3000% of 352 ft

A = final amount = unknown (what we want to find)
P = starting amount = 24000
r = growth rate in decimal form = 0.12
t = number of years elapsed = 11 (since we go from 2014 to 2025)
Plug those values mentioned into the formula. Then use a calculator to simplify
A = P*(1+r)^t
