The equation below represents Function A and the graph represents Function B:
Function A
f(x) = x - 9
Function B
graph of line going through ordered pairs negative 1, negative 3 and 2, 3
Which equation best compares the slopes of the two functions?
Slope of Function B = 2 x Slope of Function A.
Slope of Function A = Slope of Function B
Slope of Function A = 2 x Slope of Function B
Slope of Function B = - Slope of Function A
Answer: The correct option is A., i.e, Slope of Function B = 2 x Slope of Function A.
Explanation:
The given function is,
[tex]f(x)=x-9[/tex]
It can be written as,
[tex]y=x-9[/tex]
It is the slope intercept form like y=mx+c, where m is the slope. On comparing the f(x) with the slope intercept form, we get the slope of f(x) is 1.
The graph of function g(x) passing through the point (-1,-3) and (2,3).
If a line passing through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the slope of line is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{3-(-3)}{2-(-1)}=\frac{3+3}{2+1}= \frac{6}{3} =2[/tex]
The slope of g(x) is 2.
Since slope of f(x) is 1 and the slope of g(x) is 2, so we can say that the slope of function B is twice of slope of function A.
Slope of Function B = 2 x Slope of Function A
Therefore, the first option is correct.

(u, 0)
(v, w)
(0, z)
(z, 0)
the answer would be the third choice which is N(0, z)
Answer with explanation:
Vertices of Rhombus, KM LN, are : K (w,0), M (w,v) , L (u,z) and N (?).
N (?)= (x,y)
Diagonals of Rhombus Bisect each other.Diagonal, KL and MN will Bisect each other.
Mid Point Formula of Line Joining , (m,n ) and (r,s) is :
[tex]=(\frac{m+r}{2},\frac{n+s}{2})[/tex]
Mid Point of KL is
[tex]=(\frac{w+u}{2},\frac{0+z}{2})[/tex]
Mid Point of MN is
[tex]=(\frac{w+x}{2},\frac{v+y}{2})[/tex]
So, Mid point of KL = Mid Point of MN
[tex](\frac{w+u}{2},\frac{0+z}{2})=(\frac{w+x}{2},\frac{v+y}{2})\\\\ \frac{w+u}{2}=\frac{w+x}{2}\\\\x=u\\\\\frac{0+z}{2}=\frac{v+y}{2}\\\\y=z-v[/tex]
So, coordinates of Point N,can be = (u, z-v).
None, of the Option,matches with the given option.
If you will Write the rhombus as,K L MN,then also you will not get answer which matches with the options.
What is the area of the trapezoid?
30 square units
60 square units
90 square units
120 square units
Answer:
B-60
Step-by-step explanation:
The area of the trapezoid is 60 square units
How to find the area of a trapezoidThe formula for finding the area of a trapezoid is expressed as:
A = 0.5(a+b)h
Given the following parameters
a = AD = √4² + 6²
AD = √16+36
AD = √52
For the length of BC
a = AD = √6² +10²
AD = √36+100
AD = √136
Calculate the height of the trapezium (10, 6) and (8, 12)
H = √6² +2²
H = √40
Substitute
A = 1/2(7.21+11.66)*6.33
A = 60 square units
Hence the area of the trapezoid is 60 square units

Find an equation of the circle whose diameter has endpoints ( −1,−4) and (3,2) .
Final answer:
The equation of the circle with diameter endpoints (-1,-4) and (3,2) is (x - 1)^2 + (y + 1)^2 = 13, found by calculating the center at (1, -1) and the radius as sqrt(52)/2.
Explanation:
To find an equation of the circle whose diameter has endpoints at (-1,-4) and (3,2), we need to determine the center and radius of the circle. The center of a circle is the midpoint of the diameter, and the radius is half the length of the diameter.
First, we calculate the midpoint (which will be the center of the circle) using the formula: (x1 + x2)/2, (y1 + y2)/2. For the given points (-1,-4) and (3,2), the midpoint is ((-1 + 3)/2, (-4 + 2)/2), which simplifies to (1, -1). So, the center of the circle is (1, -1).
To find the radius, we use the distance formula: sqrt((x2 - x1)^2 + (y2 - y1)^2). The distance between the two points is sqrt((3 - (-1))^2 + (2 - (-4))^2), which simplifies to sqrt(4^2 + 6^2) = sqrt(16 + 36) = sqrt(52). The radius is half of the diameter, so r = sqrt(52)/2.
The standard form of a circle's equation is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius. Substituting the values we found, we get (x - 1)^2 + (y + 1)^2 = (sqrt(52)/2)^2, which simplifies to (x - 1)^2 + (y + 1)^2 = 13. This is the equation of the circle.

From home, Mary’s work is two thirds along the way to training. Training is 2.5km from work. Mary normally goes to work, then training and then home again. However, today she forgot her shoes. How far will Mary travel in total today if she has to go home before training to get her shoes?
The total distance Mary would have to travel considering she needs to return home for her shoes is 25km.
Explanation:This math problem involves the calculation of distances within a commute. Here's how we can provide a solution:
We first need to calculate how far Mary's home is to her work. If training is 2.5km from work and this represents one third of the travel (since work is two thirds along the way to training), the total distance from Mary's home to training is 2.5km * 3 = 7.5km. Thus, the distance from Mary's home to work is 7.5km * 2/3 = 5km.So, for Mary's normal route - home to work, then work to training, then training to home - she travels 5km (home to work) + 2.5km (work to training) + 7.5km (training to home) = 15km.Today, however, Mary needs to go back home from work for her shoes before she can proceed to training. This path would be: home to work (5km), work to home (5km), home to training (7.5km), and finally, training to home (7.5km) giving a total of 5km + 5km + 7.5km + 7.5km = 25km. So, Mary will travel a total of 25km today due to the forgotten shoes.Learn more about Distance calculation here:

Find the volume of the ellipsoid x^2+y^2+9z^2=64
Final answer:
The volume of the ellipsoid x²+y²+9z²=64 is 1024π/3 cubic units.
Explanation:
To find the volume of the ellipsoid given by the equation x²+y²+9z²=64, we can use the formula for the volume of an ellipsoid, which is V = (4/3)πa×b×c, where a, b, and c are the semi-axes of the ellipsoid. In our case, the ellipsoid can be rewritten to show its semi-axes clearly by dividing the equation by 64, which gives us (x²/64) + (y²/64) + (z²/(64/9)) = 1, indicating that our semi-axes are a = b = 8 and c = 8/3. Plugging these values into our volume formula gives us V = (4/3)π×8×8×(8/3), which simplifies to V = 1024π/3 cubic units.

No. We can use the pythagorean theorem to prove this.The equation being a2 + b2 = c2. We then use two of the least of the three numbers, which are 4 and 5, to substitute for “a” and “b”. We get a value for “c” which is 6.4, rounded off to the nearest tenth. This value is greater than 6. Note that this is a very logical way of solving the problem since a greater number for “a” and “b” would lead a greater value for “c”
An amount of $3000 is deposited for one year at an interest rate of 5.5% per annum. How much interest will be earned?
Answer:
$165
Step-by-step explanation:
In 1 years, you will have $165.00 of simple interest.
Calculations: The Final Investment Value, using the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods. Where r is in decimal form; r=R/100; r and t are in the same units of time.
The accrued amount of an investment is the original principal P plus the accumulated simple interest, I = Prt, therefore we have:
A = P + I = P + (Prt), and finally A = P(1 + rt)
Calculate Total Amount Accrued (Principal + Interest), solve for A
A = P(1 + rt)
Calculate Principal Amount, solve for P
P = A / (1 + rt)
Calculate rate of interest in decimal, solve for r
r = (1/t)(A/P - 1)
Calculate rate of interest in percent
R = r * 100
Calculate time, solve for t
t = (1/r)(A/P - 1)
Final answer:
The simple interest earned on a $3000 deposit at a 5.5% annual interest rate for one year is $165. This is found using the simple interest formula: Interest = Principal x Rate x Time.
Explanation:
To calculate the amount of simple interest earned on a $3000 deposit at an interest rate of 5.5% per annum for one year, we use the simple interest formula: Interest = Principal x Rate x Time.
In this case:
Principal (P) is $3000,
Rate (R) is 5.5% per annum, or 0.055 when expressed as a decimal,
Time (T) is 1 year.
So, the interest earned can be calculated as follows:
Interest = $3000 x 0.055 x 1
Interest = $165
Therefore, the amount of simple interest earned on the $3000 deposit after one year is $165.
