Answer:
Let A1 be original area
A2 dilated Area
A1=pi*d^2/4
=3.143*5^2/4
A1=19.63 unit square
A2= 3.143*15/4
A2=176.74 unit square
A2 is 9 times greater than A1
Hence the answer is B
Step-by-step explanation:
please it do in 6 min i need help with this one please The following points are from a dilation. If
B(0 , 5 ) and B'(x, 2 0 ), what is x?
Answer:
The value of x = 0
Step-by-step explanation:
Given
B(0, 5)B'(x, 20)To determine
The value of x = ?
If we closely observe the value of the y-coordinate of the image B'(x, 20), we can see that the y-coordinate of the image B' is 4 times the y-coordinate of the original point (0, 5).
i.e. y → 5×4 =20
It means the coordinates of the image B'(x, 20) can be determined by dilating the original point (0, 5) by a scale factor of 4.
Thus, the x-coordinate of B'(x, 20) can also be obtained by multiplying the x-coordinate of B(0, 5) by 4.
i.e. x → 4×0 = 0
Thus, the rule of dilation is:
P(x, y) = P'(4x, 4y)
Hence,
B(0, 5) → B'(4(0), 4(5)) → B'(0, 20)
Thus,
The value of x = 0 ∵ 0×4 = 0

15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from C on AB is 4.5 cm find its area.
Answer:
32.4 cm²
Step-by-step explanation:
Given the parallelogram ABCD ; with AB = 7.2 cm
Perpendicular from C on AB is the height of the parallelogram = 4.5 cm
Using the relation fir the area of a parallelogram :
Area of a parallelogram = base * height
Area of a parallelogram = 7.2 cm * 4.5cm
Area of parallelogram = 32.40cm²
Hence, Area of parallelogram is 32.4 cm²
Please help!
Thank you!
Answer:
y=-1/3x+10
Step-by-step explanation:
y=3x+1
The line perpendicular would have a negative reciprocal of the slope of 3 which means that you would add a negative sign and then flip 3/1 into 1/3 resulting in -1/3 as the slope.
To find the line that passes through the point (6,8) you would plug the values into the equation y=mx+b
m=-1/3x as found above
6 is the x-value and 8 is the y-value
8=(-1/3)(6)+b
8=-2+b
Add 2 on both sides and you get b to equal 10
Isabel's family decided to get rid of their cable TV. Originally they were paying $84.00 for the TV, internet and phone, but now they're paying $57.12. What was the percent the bill decreased by?
Answer:
32%
Step-byentrepreneurstion:
The first step is to calculate the decrease
= $84 - $57.12
= $26.88
Therefore the decrease can be calculated as follows
= 26.88/84 ×100
= 0.32×100
= 32%
Hence the bill decreased by 32%
If possible can I get help on both?

Write an equation for the translation of [tex]y\frac{3}{x}[/tex] that has the asymptotes x = 6 and y = -6.
Show all your steps, then graph it. (Be sure to link the graph with your steps.)
a.) [tex]y=\frac{3}{x+6}-6[/tex]
b.) [tex]y=\frac{3}{x-6}+6[/tex]
c.) [tex]y=\frac{3}{x-6}-6[/tex]
d.) [tex]y=\frac{3}{x+6}+6[/tex]
______________________________
1.) Substitute x, y, and general form using the formulas:Formula for x: [tex]x=d=6[/tex]Formula for y: [tex]y=k=-6[/tex]Formula for general form y: [tex]y=\frac{a}{x-d}+k=y=\frac{3}{x-6}+(-6)[/tex]Note:
- When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.
Equation at the end of Step 1:
[tex]y=\frac{3}{x-6}+(-6)[/tex]2.) Simplify the d and k forms:[tex]y=\frac{3}{x-6}+(-6)=y=\frac{3}{x-6}-6[/tex]Note:
- The x(d) stays the same since the 6 was positive and we plugged it in making it negative, so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.
- The y(k) changes from [tex]+(-6)[/tex] to [tex]-6[/tex] because when a [tex](+)[/tex] and [tex](-)[/tex] are next to each other, the rule is [tex]+<-[/tex]. The Minus always wins in this type of problem situation.
So the answer is c, [tex]\bold{y=\frac{3}{x-6}-6}[/tex].

During a hockey game, the puck slid 27meters across the ice rink as it was chased by a hockey player skating at 9.5 meters per second. The puck slid that distance in 1.5seconds at a steady speed. What was the puck's speed
Answer:
Speed of Puck is 18 m/s
Step-by-step explanation:
Mathematically;
speed = distance/ time
The puck traveled a distance of 27 m in 1.5 seconds
The speed of the puck is thus;
27/1.5 = 18 m/s

Given that 1 inch = 2.54 cm, how many centimeters are there in 7 feet? Answers may be written using decimals form and should be rounded to the nearest hundredth when necessary
Answer:
There are 213.36 centimeters in 7 feet.
Step-by-step explanation:
It is given that:
1 inch = 2.54 cm
We have to find centimeters in 7 feet.
We will convert feet to inches.
1 feet = 12 inches
7 feet = 12*7 = 84 inches
Now,
1 inch = 2.54 cm
84 inches = 2.54 * 84
84 inches = 213.36 cm
Therefore,
There are 213.36 centimeters in 7 feet.
