ASAP!!! A bike trail starts at (4.2,−30.5) and ends at (4.2,9.7) on a map. Each unit represents 1 kilometer. What is the distance from start of the trail to the end?
Explanation:
The x coordinates are the same, so we subtract the y coordinates and use absolute value to ensure the result isn't negative.
|-30.5 - 9.7| = |-40.2| = 40.2
One unit represents 1 km, so 40.2 units represent 40.2 km
This converts to 40,200 meters. Multiply by 1000 to go from km to meters.

You have the following function:

[tex]\frac{f(x+h)-f(x)}{h}[/tex]Consider that f(x + h) is given by:
[tex]f(x+h)=(x+h)^2+8=x^2+2xh+h^2[/tex]Then, by replacing f(x) and f(x+h) into the difference quotient and by simplifying, you get:
[tex]\begin{gathered} \frac{f(x+h)-f(x)}{h}=\frac{x^2+2xh+h^2+8-x^2-8}{h} \\ \frac{f(x+h)-f(x)}{h}=\frac{2xh+h^2}{h}=\frac{h(2x+h)}{h}=2x+h \end{gathered}[/tex]Hence, the result to the quotient difference is 2x + h
Given f(x)=2x^3+kx-11 and x-1 is the factor of f(x), then what is the value of k?
The value of k in the expression is equal to 9.
The expression is in the form of Cubic polynomial. A cubic polynomial is the one which can be written in the form y = ax³ + bx² + cx + d where a, b, c and d are coefficients and x, and y are independent and dependent variables respectively. The cubic polynomial f(x) = 2x³ + (k)x - 11 has a factor equal to (x-1). If it is the factor, then x = 1 is the solution of cubic polynomial and at x = 1 the value of f(x) = 0.
2(1)³ + k(1) - 11 = 0
2 + k - 11 = 0
k - 9 = 0
=> k = 9 which is the required value.

Calculate the volume of a hemisphere.. diameter is 11cm
Pls help with all steps
The volume of the hemisphere is found as 695.55 cm³.
What is termed as the hemisphere?The term hemisphere can be broken down into hemi as well as sphere, where hemi implies half and sphere is a 3D mathematical shape. As a result, a hemisphere is a three-dimensional geometric shape that really is half of a sphere, with one side flat and the other as a circular bowl. It is created by cutting a sphere at the centre point along its diameter, resulting in two equal hemispheres. The base or face of the hemisphere is the flat face of a hemisphere.The formula for finding the volume of the hemisphere is;
V = (4/3)πr³
where, π = 3.14
r = radius
For the given question, the diameter of the hemisphere is 11 cm.
Radius = 11/2 = 5.5 cm.
Put the value in formula.
V = (4/3)×3.14×5.5³
V = 695.55
Thus, the volume of the hemisphere is found as 695.55 cm³.

chegg tell whether each sequence is arithmetic. if the sequence os arithmetic, identify the common difference and find the indicated term 3,5/2,3/2,-3/2,...
Take the 2nd term and minus the 1st term.
Now take the 3rd term and minus the 2nd term.
Notice that the differences are the same. Hence there is a common difference (difference of -0.5).
So it is an arithmetic sequence.
here are the first 5 terms in a number sequence 7 10 13 16 19
write an expresstion, in terms of n, for the nth term of this number sequence.
Answer:
[tex]a_{n}[/tex] = 3n + 4
Step-by-step explanation:
there is a common difference between consecutive terms , that is
10 - 7 = 13 - 10 = 16 - 13 = 19 - 16 = 3
this indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 7 and d = 3 , then
[tex]a_{n}[/tex] = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

what is the slope of a line perpendicular to the line whose equation is x+4=28
The slope of a line perpendicular to the line is -4
The equation is x -4y = 28
The equation for the line is
y = mx + c
where m = slope
c = y-intercept
Here the equation is x - 4y = 28
4y = x - 28
y = x/4 - 7
So the slope of this line is 1/4
Now we have to find the slope of the line perpendicular to that line.
We know that,
m1 × m2 = -1
1/4 × m2 = -1
m2 = -4
Therefore the slope of the line perpendicular to the line is -4.

Answer: The answer for X' is -1,8, and the answer for X'' is 3,14
Step-by-step explanation:
When talking about reflections across the x-axis, the formula would be: (x,y)---> (x, -y) so you first start out with -1, -8 then translate it to -1,8, because you swap the y. Then you add 4 to -1 because you move 4 to the right which gives you 3, and then you add 6 to 8 because you move up 6, which gives you 14, so your final answer is 3,14

2. Alisha Gregory is a telephone installer. She is married and claims 2 allowances.
Her state personal exemptions total $76.92 per week. The state tax rate is 3.0% of
taxable income. Local income tax is 1.5% of gross. Medical insurance costs $1,940
a year, of which the company pays 60%.
The net pay of Alisha Gregory is $30606.4
Since we are given the weekly gross pay of her is $640
The annual gross pay will be 52 * 640 =33280.
Here the local income tax is 1.5% of the gross, which is 1.5/100 * 33280 = 499.2 and it is also specifically said that the state tax is the 3.0% of taxable income.
So we have:
3/100 * 33280= 998.4
The medical insurance is $1,940 for a year from where the company pays 60 %
For which we have:
60/100 *1940
= 1164
At the last he pays $4.50 for union dues and $7.50 for others.
Since we know that the net pay is nothing but the amount we get after subtracting the deductions from the annual gross pay
So the net pay = 33280- (499.2+998.4+1164+4.50+7.50)
= 33280 -(2673.6)
= 30606.4

What are mathematical operators?Any symbol that denotes a mathematical operation is known as an operator. Examples are d/dx and Square root of x (which implies that the square root should be taken) (which indicates differentiation with respect to x is to be performed).
What are the five mathematical operators?These operators are + for addition, - for subtraction, * for multiplication, / for division, and % for percentage (modulo).
So:
2+1=3
40+9=49
56+3=59
2*0=0
5*5=25

-12=-6(-8n+6) + 8(-4+n)
Answer:
n = 1
Step-by-step explanation:
-12 = -6(-8n + 6) + 8(-4 + n)
multiply our right side:
-12 = 48n - 36 -32 + 8n
combine n terms on right side:
-12 = 56n - 36 -32
combine numbers on right side:
-12 = 56n - 68
add 68 to both sides:
-12 + 68 = 56n - 68 + 68
56 = 56n
divide both sides by 56:
56/56 = 56n/56
n = 1
check:
-12 = -6(-8(1) + 6) + 8(-4 + (1))
-12 = -6(-8 + 6) + 8(-3)
-12 = -6(-2) + 8(-3)
-12 = 12 - 24
