Answer:
Function 2.
Step-by-step explanation:
For the first equation, the y-intercept is the 'b' value in the equation
y = mx + b.
In the equation given, b = 5. This is the y-intercept for the equation.
To find the y-intercept, you need to look for the 'y' value at x = 0. Therefore:
In the table, notice that when t = 0, r = 5.25. This is the same as x = 0, y = 5.25. This means that the y-intercept of the table is y = 5.25.
Since 5.25 > 5, function 2 has a greater y intercept.

Answer:
(1/6)^2
Step-by-step explanation:
We want to find the fraction that is equivalent to 1/36.
Let us look at each of them individually:
a. [tex](\frac{1}{108})^3 = \frac{1}{1259712}[/tex]
b. [tex](\frac{1}{9})^4 = \frac{1}{6561}[/tex]
c. [tex](\frac{1}{6})^2 = \frac{1}{36}[/tex]
d. [tex](\frac{1}{5})^2 = \frac{1}{25}[/tex]
Therefore, the correct answer is c.

Answer:
V is inside the circle.
Step-by-step explanation:
We work out the radius of the circle which is the distance between K (0,0) and (6, -4).
Radius = √[(6 - 0)^2 + (-4 - 0)^2]
= √(16 + 36)
= √52.
Now find the distance of point V from K(0,0):
= √((√2-0)^2 + (-7-0)^2]
= √(2 + 49)
= √51.
This is less than the radius of the circle, so V lies inside it.

The area of a rectangle is 252 cm², and the length is 3 less than 2 times the width. Find the dimensions of the rectangle.
Answer:
21cm, 12cm
Step-by-step explanation:
width=x cm
length=2x-3 cm
area= 252cm²
l*b= 252 cm²
(2x-3)(x)=252
2x²-3x= 252
this is how I did it
we need to find the nearest square of the number (it should be lesser than the area)
that is 225, whose square root is 15.
since there is a coefficient to the x², the value of x would be calculate like this 15- (2+1)= 15-3 = 12
x= 12
we can verify it too,
2*(12)² - 3*12=252
288-36=252
252=252
therefore width is 12 cm and width is 2*12-3= 24-3= 21 cm
verify;
21*12= 252
252=252
hence the dimensions are 12 am (width) and 21 cm(length).

A. 6.28 ft2
B. 18.28 ft2
C. 22.28 ft2
D. 28.56 ft2
Answer:
C. 22.28
Step-by-step explanation:
area of square is 4*4 =16
area of half of circle is
(Pi*r²)/2 = 3.14*4/2 = 6.28
16+6.28 = 22.28
Answer:
C. 22.28
Step-by-step explanation:
4 x 4 = 16 (Pi x r²)/2 = 3.14 x 4/2 = 6.28
16 + 6.28 = 22.28

he following shows the height, in inches, of the players on the opening night roster of 2015-2016 New York Knicks.
84, 80, 87, 75, 77, 79, 80, 74, 76, 80, 80, 82, 82
1. What is the median?
2. What is the mean?Show your work.
3. What is the typical height of a Knicks basketball player? Explain.
Answer:
median = 80 inches
mean = 79.692 inches
typical height = 80 inches
Step-by-step explanation:
Given height
84, 80, 87, 75, 77, 79, 80, 74, 76, 80, 80, 82, 82
arranging the height in increasing order we have
74,75,76,77,79,80,80,80,80,82,82,84,87
no, of terms in the heights = 13
We know
that median for any data set is the middle number, if data is arranged in increasing order of their occurrence.
If the number of terms is odd, then median is (n+1)/2 th term
If the number of terms is even, then median is taken average of n/2 th term and( n/2 + 1)th term .
________________________________________
since here number of term is 13.
then median will be (13+1)/2 th term
i.e 7th term
as shown above seventh term is 80.
1. What is the median?
answer: Median is 80
_____________________________________
Mean is calculated average of all the terms
mean = sum of all the terms/ number of terms
mean = 74+75+76+77+79+80+80+80+80+82+82+84+87/13
= 1036/13 = 79.692
Thus, means is 79.692
2. What is the mean?
Answer: Mean is 79.692
3. What is the typical height of a Knicks basketball player? Explain
Answer: Typical height for basket ball player will the height which is the most commonly occurring height in the group.
The most commonly occurring data in the data set is also called mode.
Since, in this data group 80 inches occurring most number of times i.e 4 times.
Thus, typical height of group is 80 inches.
find the coordinates of C' after a reflection across the line
y = 1 and then x = 2. Write in the form (a,b)
Part 5a
==============================================================
Explanation:
C is at (0,0). Ignore the other points.
Reflecting over y = 1 lands the point on (0,2) because we move 1 unit up to arrive at the line of reflection, and then we keep going one more unit (same direction) to complete the full reflection transformation. I'll call this point P.
Then we reflect point P over the line x = 2 to arrive at the location Q = (4,2). Note how we moved 2 units to the right to get to the line of reflection, and then keep moving the same direction 2 more units, then we have applied the operation of "reflect over the line x = 2"
So we have started at C = (0,0), moved to P = (0,2) and then finally arrived at the destination Q = (4,2). This is the location of C' as well.
All of this is shown in the diagram below.

Answer:
a) [tex]x = 10^{18}\,\mu m^{2}[/tex], b) [tex]x = 10^{18}[/tex], c) [tex]x = 10^{21}\,\mu m^{2}[/tex], d) [tex]x = 10^{21}[/tex], e) [tex]x = \frac{1}{10^{21}}[/tex], f) [tex]x = 10^{3}\,nm^{2}[/tex], g) [tex]x = 10^{3}\,nm^{2}[/tex]
Step-by-step explanation:
a) The product of one terameter and one micrometer is:
[tex]x = (1\,tm)\cdot (10^{12}\,\frac{m}{tm})\cdot (10^{6}\,\frac{\mu m}{m} ) \cdot (1\,\mu m)[/tex]
[tex]x = (10^{18}\,\mu m)\cdot (1\,\mu m)[/tex]
[tex]x = 10^{18}\,\mu m^{2}[/tex]
b) The quotient of one terameter and one micrometer is:
[tex]x = \frac{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{6}\,\frac{\mu m}{m} )}{1\,\mu m}[/tex]
[tex]x = \frac{10^{18}\,\mu m}{1\,\mu m}[/tex]
[tex]x = 10^{18}[/tex]
c) The product of terameter and one nanometer is:
[tex]x = (1\,tm)\cdot (10^{12}\,\frac{m}{tm})\cdot (10^{9}\,\frac{nm}{m} ) \cdot (1\,nm)[/tex]
[tex]x = (10^{21}\,nm)\cdot (1\,nm)[/tex]
[tex]x = 10^{21}\,\mu m^{2}[/tex]
d) The quotient of one terameter and one nanometer is:
[tex]x = \frac{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{9}\,\frac{nm}{m} )}{1\,nm}[/tex]
[tex]x = \frac{10^{21}\,nm}{1\,nm}[/tex]
[tex]x = 10^{21}[/tex]
e) The quotient of one nanometer and one terameter is:
[tex]x = \frac{1\,nm}{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{9}\,\frac{nm}{m} )}[/tex]
[tex]x = \frac{1\,nm}{10^{21}\,nm}[/tex]
[tex]x = \frac{1}{10^{21}}[/tex]
f) The quotient of one nanometer and one micrometer is:
[tex]x = \frac{1\,nm}{(1\,\mu m)\cdot (10^{3}\,\frac{nm}{\mu m} )}[/tex]
[tex]x = \frac{1\,nm}{10^{3}\,nm}[/tex]
[tex]x = \frac{1}{10^{3}}[/tex]
g) The product of one nanometer and one micrometer is:
[tex]x = (1\,nm)\cdot (1\,\mu m)\cdot (10^{3}\,\frac{nm}{\mu m} )[/tex]
[tex]x = 10^{3}\,nm^{2}[/tex]

Two rectangular pyramids are similar. The smaller pyramid has a volume of 12 cubic feet, and
the larger pyramid has a volume of 324 cubic feet. If the smaller pyramid has a height of 6 feet,
what is the exact height (in feet) of the larger pyramid?
Volume of Big Pyramid= 324 cubic feet
Volume of small pyramid= 12
Volume of a pyramid is given as V=⅓xBasexheight
For the big pyramid
324=⅓xbasexheight
But 324= 27x12
Then for the big pyramid,
12=1/3x1/27xbasexheight
For the small pyramid
12=1/3xbasex6
Since both base are similar and from the equations derived so far
1/3x1/27xheight=1/3x6
Height=27x3x1/3x6=162feet

Answer:
[tex]f(4) = \frac{256}{3}[/tex]
Step-by-step explanation:
To find f(4), '4' will need to be substituted in place of 'x'. Therefore:
[tex]f(x)\frac{1}{3} * 4^{x}[/tex] becomes:
[tex]f(4) = \frac{1}{3}* 4^{4}[/tex]
Simplify:
[tex]f(4) = \frac{1}{3}* 256\\ \\f(4) = \frac{256}{3}[/tex]
Therefore, f(4) equals [tex]\frac{256}{3}[/tex]
