Given n(t) = -2(t+5)2 +4, find n(-8).

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]

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.

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]

Answer:

the solution is (0,2) to the problem

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:

-8

Step-by-step explanation:

47 = -7x -9

Add 9 to each side

47+9 = -7x-9+9

56 = -7x

divide each side by -7

56/-7 = -7x/-7

-8 = x

Answer:

Step-by-step explanation:

First we rewrite the expression:

 3sec (x) -2 = 1

 3 (1 / cos (x)) -2 = 1

 3 (1 / cos (x)) = 1 + 2

 3 (1 / cos (x)) = 3

 (1 / cos (x)) = 3/3

 cos (x) = 1

 x = 2 * pi * n

 on the interval [0, 2pi):

 x = 0

 Answer:

 x = 0 on the interval [0, 2pi)

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:

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).

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:

10/8 pounds

Step-by-step explanation:

Answer:

5/4 or 1.25 pounds of choclate chips

Step-by-step explanation:

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:

Quadrant 4

Step-by-step explanation:

Answer: 4

Step-by-step explanation:

==============================================================

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.
