why two +Eleven + nine




​

Answer:

15.99 or rounded to 16 days

Step-by-step explanation:

1,840 divided by 805 = 2.28

2.28 times 7 = 15.99

Step-by-step explanation:

There are seven days in one week. To find out how much money this man earns in ONE day, you can divide $805 by 7 days like so:

$805 / 7 days = $115 per day

To find out how many days it takes for the man to earn $1,840, you must divide $1,840 by $115 to get the number of days like so:

$1,840 / 115$ = 16 days

Therefore, the man earns $1,840 in 16 days.

Answer:

\(f\left(\dfrac{1}{2}\right)=0\)

Step-by-step explanation:

Given polynomial:

\(f(x) = 4x^3 - 6x^2 + 8x - 3\)

The zeros of a function are the values of the variable that make the function zero.  Therefore, if c = 1/2 is a zero of f(x), then f(1/2) = 0.

According to the factor theorem, if f(x) is a polynomial, and f(c) = 0, then (x - c) is a factor if f(x). Given c = 1/2, then (x - 1/2) is a factor of f(x).

Therefore, to show that c is a zero of f(x), divide f(x) by (x - 1/2) using synthetic division.

\(\textsf{Dividend:}\quad 4x^3 - 6x^2 + 8x - 3\)

\(\textsf{Divisor:} \quad \left(x-\dfrac{1}{2}\right)\)

Perform Synthetic Division

Place the zero "c" in the division box.

Write the coefficients of the dividend in descending order.

(Note: As no terms are missing, we do not need to use any zeros to fill in missing terms).

\(\begin{array}{c|rrrr}\vphantom{\dfrac12}\frac{1}{2} & 4 & -6 & 8 & -3\\\cline{1-1}\end{array}\)

Bring the leading coefficient straight down:

\(\begin{array}{c|rrrr}\vphantom{\dfrac12}\frac{1}{2}&4&-6&8&-3\\\cline{1-1}&\downarrow &&&\\\cline{2-5}&4&&&\end{array}\)

Multiply the number you brought down with the number in the division box and put the result in the next column (under the -6):

\(\begin{array}{c|rrrr}\vphantom{\dfrac12}\frac{1}{2}&4&-6&8&-3\\\cline{1-1}&\downarrow &2&&\\\cline{2-5}&4&&&\end{array}\)

Add the two numbers together and put the result in the bottom row:

\(\begin{array}{c|rrrr}\vphantom{\dfrac12}\frac{1}{2}&4&-6&8&-3\\\cline{1-1}&\downarrow &2&&\\\cline{2-5}&4&-4&&\end{array}\)

Repeat:

\(\begin{array}{c|rrrr}\vphantom{\dfrac12}\frac{1}{2}&4&-6&8&-3\\\cline{1-1}&\downarrow &2&-2&\\\cline{2-5}&4&-4&6&\end{array}\)

\(\begin{array}{c|rrrr}\vphantom{\dfrac12}\frac{1}{2}&4&-6&8&-3\\\cline{1-1}&\downarrow &2&-2&3\\\cline{2-5}&4&-4&6&0\end{array}\)

The bottom row (except the last number) gives the coefficients of the quotient. The degree of the quotient is one less than that of the dividend.

The last number in the bottom row is the remainder.

Therefore:

As the remainder is f(c) then:

\(f\left(\dfrac{1}{2}\right)=0\)

243

Step-by-step explanation:

3*3*3*3*3=243

Answer:

243

Step-by-step explanation:

C(x) = 0.25x + 45 , Slope is .25 dollars per mile and the y intercept is 45 dollars.

Given,

The cost C(ar), where a is the number of miles driven, of renting a car for a day is $45 + $0.25 per mile.

To find the slope , y - intercept and C(a)

Now, According to the question:

A renting a car for a day is $45 plus  $0.25 per mile.

C(x) = 0.25x + 45

This is in the form y = mx + b where m is the slope and b is the y intercept

The slope is .25 dollars per mile and the y intercept is 45 dollars

Hence, C(x) = 0.25x + 45 , Slope is .25 dollars per mile and the y intercept is 45 dollars.

Ounces are typically used to measure liquid, so I would discourage choosing the top two. And, hopefully you know by now that an orange does not weigh 8 pounds.

9514 1404 393

Answer:

  (a)  0.8 ounces (most precision)

  (b)  8 ounces (best precision for likely weight of an orange)

Step-by-step explanation:

The most precision is obtained by using the smallest unit of measure. On this list, the smallest unit of measure is a tenth of an ounce. That is, the measure 0.8 ounces has the most precision.

__

It is unlikely that the weight of one orange will be 0.8 ounces. The smallest unit used in a measurement likely to correspond to the weight of an orange is 1 ounce, used in the measurement 8 ounces. That measurement has better precision than 0.8 pounds, because 0.1 pounds corresponds to 1.6 ounces.

Answer:

C

Step-by-step explanation:

Answer:

19/20 , 1 1/4 , 1 4/5

Step-by-step explanation:

1.8 = 1 4/5 (fraction)

1.8 converts to 18/10. This can be simplified twice, firstly by making it 9/5 since both 18 and 10 are divisible by two, but can be simplified further to 1 4/5

1.25 = 1 1/4 (fraction)

1.25 converts to 125/100. This can be simplified to 5/4 or 1 1/4

0.95 = 19/20 (fraction)

0.95 converts to 95/100. This can be simplified to 19/20

Ascending Order (smallest to largest)

smallest - 19/20

middle - 1 1/4

largest - 1 4/5

Answer:

AB=21 miles

Step-by-step explanation:

Since it's a right angles triangle, we'll use Pythagoras theorem

HYPOTENUSE ²= base² + perpendicular ²

Where hyp=AB, base=16 and perp=13

AB²=16²+13²

AB²=256+169

AB²=425

Taking sq root.

AB=20.6 miles

AB≈21 miles

The possible values for angles 1, 2, and 3 given that lines a and b are parallel lines include the following:

In Mathematics and Geometry, parallel lines are two (2) lines that are always the same (equal) distance apart and never meet or intersect.

Note: Assuming angle 1 is equal to 60 degrees.

In Mathematics and Geometry, the vertical angles theorem states that two (2) opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other:

m∠1 ≅ m∠3 = 60°.

Based on the linear pair postulate, the measure of angle 2 can be determined as follows;

m∠1 + m∠2 = 180°

60° + m∠2 = 180°

m∠2 = 180° - 60°

m∠2 = 120°

Step-by-step explanation:

Given parallelogram JKLM with:

Find:

We know opposite angles of parallelogram are congruent:

Use angle addition postulate:

Step-by-step explanation:

the formula of the "relation" is

x² + y² = r²

this is for circle with its center at the origin.

now that gives us

y² = r² - x²

y = ±sqrt(r² - x²)

a. this ± of the square root gives us the 2 functions.

y = sqrt(r² - x²)

y = - sqrt(r² - x²)

as it is a circle, the ranges and domains are the same.

domain is the allowed number interval for x, and range is the number interval for y (the function results).

both are

-r <= x <= r

outside of that range the square root argument becomes negative, and that is undefined for R (the set of real numbers).

b. if we want to see it that way, we can say that

f(x) = r² - x²

g(x) = sqrt(x)

and so

sqrt(r² - x²) = g(f(x))

a function into function.

c. let's pick the "positive" semicircle

y = g(f(x)) = + sqrt(r² - x²)

f(x) = r² - x²

the domain is all x (-infinity < x < +infinity)

the range is (-infinity < y <= r²), as negative and positive larger x will turn f(x) negative. the functional results cannot get bigger than r² (for x=0).

g(x) = +sqrt(x)

the domain is all positive x incl. 0 (0 <= x < +infinity), as sqrt is not defined for negative values. at least not in R.

the range is also all possible positive values incl. 0

(0 <= y < +infinity).

d.

A one-to-one correspondence function is a function between the elements of the two sets of domain and range, where each element of one set is paired with exactly one element of the other set, and each element of the other set is paired with exactly one element of the first set.

that means, every x value creates exactly one y value, and no y value occurs more than once.

this is no true for

f(x) = r² - x²

because for -r <= x <= r we get the same y for -x and +x.

it is true for

g(x) = sqrt(x), as no 2 different numbers have the same square root.

Answer:

please see answers below

Step-by-step explanation:

In a right-angled triangle, a ² + b ² = c ².

angles in a triangle add up to 180°.

Sine rule:   a/SIN A  =  b/SIN B  =   c/SIN C

angle C = 90° (little square means 90).

if angle A is 30, then angle B must be 180 - 90 - 30 = 60°.

using the Sine rule:

a/Sin A  =  c/Sin C

multiply both sides by Sin A:

a = (c Sin A) / Sin C

= (12 Sin 30) / Sin 90

= 6.

so a = 6.

Using Pythagoras (In a right-angled triangle, a ² + b ² = c ²),

c² = a² + b²

b² = c² - a²

= 12² - 6²

= 144 - 36

= 108

so b² = 108

b = √108

angle B is correct

Answer:

13 ingredients

Step-by-step explanation:

The number of different recipes that can be made from 2 ingredients = 78

Since there are no two recipes that share the exact same two ingredients ;

The number of recipes in Mark's kitchen is:

nCk = 78

k = Number of ingredients per recipe = 2

n = total number of ingredients in kitchen

Total recipes made = 78

n! / (n-r)!r! = 78

n! / (n - 2)!2! = 78

n(n-1)(n-2)! / (n-2)! * 2 * 1 = 78

n(n - 1) / 2 = 78

n(n-1) = 156

n² - n = 156

n² - n - 156 = 0

Factorize :

n² - 13n + 12n - 156 = 0

n(n - 13) +12(n-13) = 0

(n-13) = 0 ; (n+12) = 0

n = 13 or n = - 12

n cannot be negative

Hence, n = 13

Number of ingredients is 13
