Answer:
Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, so to make a rotation in one 24-hour period, equatorial regions race nearly 1,600 kilometers (1,000 miles) per hour. Near the poles, Earth rotates at a sluggish 0.00008 kilometers (0.00005 miles) per hour.

Simplify 4n5 + 3.5n5 + (-2.1n5).
4.4 n5
5.4 n5
20 n5
6.4 n5
Answer:
[tex]4 {n}^{5} + 3.5 {n}^{5} + ( - 2.1 {n}^{5} )[/tex]
first create a bracket:
[tex] = ( {4n}^{5} + 3.5 {n}^{5} ) + ( - 2.1 {n}^{5} )[/tex]
then solve the first bracket:
[tex] = {7.5 {n}^{5} } + ( - 2.1 {n}^{5} )[/tex]
then open the remaining bracket:
[tex] = {7.5n}^{5} - {2.1n}^{5} [/tex]
carryout the subtraction operation:
[tex] = (7.5 - 2.1) {n}^{5} \\ { \boxed{ = {5.4n}^{5} }}[/tex]

Find the center of a circle with the equation: x2+y2−4x+2y−11=0 x 2 + y 2 − 4 x + 2 y − 11 = 0
Answer:
( 2, - 1 )
Step-by-step explanation:
( x - h )² + ( y - k )² = r²
( h, k ) are coordinates of the center of a circle with radius r
~~~~~~~~~
x² + y² - 4x + 2y - 11 = 0
( x² - 4x + 4 ) - 4 + ( y² + 2y + 1 ) - 1 - 11 = 0
( x - 2 )² + ( y + 1 )² = 4²
Coordinates of the center of a circle are ( 2, - 1 )
2. What value of x makes the equation 4 - 3x = 19 true?
Answer:
x = -5
Step-by-step explanation:
If you want the value of x and it should be true we first need to find the value of x
4 - 3x = 19
-3x = 19 - 4
-3x = 15
x = 15/-3
x = -5
if x is a rational number and y=2/3, which statement describess the sum of x and y?
Answer:
The answer is: The sum of x and y is a rational number.
Step-by-step explanation:
x is a rational number (any).
[tex]\frac{2}{3}[/tex] is a rational number too.
So, the sum of x and y will also be a rational number.
find the range of possible values for x
[tex]\\ \rm\longmapsto x-5=41[/tex]
[tex]\\ \rm\longmapsto x=41+5[/tex]
[tex]\\ \rm\longmapsto x=46[/tex]
Hence
[tex]\\ \rm\longmapsto 45<x<47[/tex]

Find the x-intercept and y-intercept of the line.
4x+5y= -20
Answer:y-intercept = -20/5 = -4 x-intercept = -20/4 = -5
Step-by-step explanation:
Answer:
x- intercept = - 5, y- intercept = - 4
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis.
The y- coordinate of any point on the x- axis is zero
Substitute y = 0 into the equation and solve for x
4x + 5(0) = - 20
4x = - 20 ( divide both sides by 4 )
x = - 5 ← x- intercept or (- 5, 0 ) in coordinate form
The y- intercept is where the line crosses the y- axis
The x- coordinate of any point on the y- axis is zero
Substitute x = 0 into the equation and solve for y
4(0) + 5y = - 20
5y = - 20 ( divide both sides by 5 )
y = - 4 ← y- intercept or (0, - 4 ) in coordinate form
А football player shoot to score When he is 12m from one goal post and 6m from the other. If the goal posts are 7m apart, within what angle must a ground Shoot be made to score
Answer:
24.54°Step-by-step explanation:
The three segments make a triangle with sides 6, 7 and 12 m.
We need to find the angle opposite to side 7 m.
Use the low of cosines to work out the angle x:
cos x = (6² + 12² - 7²)/(2*6*12)cos x = 0.9097x = arccos (0.9097)x = 24.54° (rounded)Shevonia wants to decrease her energy bill by 189. If her

Kelly works two jobs. She usually works at a retail store for 7 hours during the day and is paid $11.72 per hour by the store. In the evening she works at a restaurant as a manager for 6 hours and is paid $8.96 per hour. How much does she make on average per hour for the day?
Answer:
$10.44
Step-by-step explanation:
Day - 7 hours
one hour - $11.72
7 hrs = (7 × $11.72)
Total per day = $82.04
Evening- 6 hours
1 hour- $8.96
6 hours =(6 × $8.96)
= $53.76
Average = total amount of money ÷ total amount of hours worked
= ($82.04 + $53.76) ÷ ( 7 + 6 )
= 135.8 ÷ 13
= $10.44

Two dice are rolled. A = ‘sum of two dice equals 3’ B=‘sumoftwodiceequals7’ C=‘at
least one of the dice shows a 1’ (a) What is P (A|C)?
(b) What is P (B|C)?
(c) Are A and C independent? What about B and C?
Presumably, the two dice are fair, so that each face has an equal 1/6 probability of being rolled. We roll 2 dice, so there are 6² = 36 possible outcomes, each with 1/36 probability of occurring.
We have
• P(A) = 2/36 = 1/18, because there are only 2 ways to roll a sum of 3 (1+2 and 2+1)
• P(B) = 6/36 = 1/6, because there are 6 ways of rolling a sum of 7 (1+6, 2+5, 3+4, 4+3, 5+2, 6+1)
• P(C) = 12/36 = 1/3, because if 1 die shows a 1, then there are 6 possible values for the other die, and vice versa)
(a) By definition of conditional probability,
P(A | C) = P(A and C) / P(C)
A and C only occur together if we had rolled either {1, 2} or {2, 1}, so ultimately
P(A and C) = P(A)
so that
P(A | C) = (1/18) / (1/3) = 3/18 = 1/6
(b) From the definition,
P(B | C) = P(B and C) / P(C)
By the same reasoning as in (a), we have to roll either {1, 6} or {6, 1} to have both B and C occur, so
P(B and C) = (2/36) / (1/3) = 6/36 = 1/6
(c) In order for two events X and Y to be independent, we need to have
P(X and Y) = P(X) P(Y)
or in terms of conditional probability,
P(X | Y) = P(X and Y) / P(Y) = P(X) P(Y) / P(Y) = P(X)
Then it follows that A and C are not independent, while B and C are independent.
