Answer:

4 1/20

Step-by-step explanation:

1 4/5 - (-2 1/4) You need the closing bracket.

1 4/5 + 2 1/4

Change to improper fractions.

[tex]\frac{5*1 + 4}{5} + \frac{4*2+1}{4}[/tex]

9/5 + 9/4               Change so that both have the same denominator.

[tex]\frac{9*4}{5*4} + \frac{9*5}{4*5}[/tex]

36/20 + 45/20

81/20 which believe it or not is an acceptable answer.

4 1/20  is another acceptable answer

Answer:

C

Step-by-step explanation:

This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.

Answer:

A isnt the correct answer. B doesnt seem reasonable because its one specific item. D means they arent exactly a customer since they didnt buy anything therefore the answer would be C

C is your answer.

not sure about it tho but its what i would put

Answer:

They will meet in 2.25 hours or 2 hours 15 minutes

Step-by-step explanation:

At any point in time;

distance = speed * time

Let the number of hours at which they meet be x

In x hours, the distance traveled by Karen will be 59 * x = 59x miles

In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles

Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed

However, the sum of whatever they have traveled will be equal to the distance between them

thus;

59x + 65x = 279

124x = 279

x = 279/124

x = 2.25 hours

Step-by-step explanation:

The inverse of the function for  [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex]  is  [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]

"The inverse function of a function f (also called the inverse of f ) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by  [tex]f^{-1}[/tex]."

We have

[tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex]

Replace g(x) with y

[tex]y =[/tex] [tex]\frac{x^{3} }{8}+16[/tex]

Interchange the variables

[tex]x= \frac{y^{3} }{8}+16[/tex]

Rewrite the equation as

[tex]\frac{y^{3} }{8}+16= x[/tex]

⇒[tex]\frac{y^{3} }{8}= x-16[/tex]

Multiply both sides of the equation by 8

[tex]8.\frac{y^{3} }{8}=8(x-16)[/tex]

⇒[tex]{y^{3} }=8(x-16)[/tex]

⇒[tex]{y^{3} }=8x-128[/tex]

⇒[tex]{y} }=\sqrt[3]{8x-128}[/tex]

⇒[tex]{y} }=2\sqrt[3]{x-6}[/tex]

Replace y with [tex]g^{-1}(x)[/tex]

⇒[tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]

Hence, The inverse of the function for  [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex] is  [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]

50-32*8

Step-by-step explanation:

Answer:

50-32<8

Step-by-step explanation:

Answer:

11.4 metres

Step-by-step explanation:

Use Pythagoras theorem for a right-angled triangle

a^2 + b^2 = c^2

if you cut the rectangle in half, it will become a right angled triangle.

a and b are two sides of the rectangle, while c is the diagonal or hypothenuse

so 9^2 + 7^2 = c^2

81 + 49  = c^2

c^ 2 = 130

square root 130 = c

you should get approximately 11.4 metres

Answer:

a)  0

b) -5

Step-by-step explanation:

We want to find f(x) = -4

This means find the value of x  where y=-4

The value of x  where y=-4 is x=0

Then find f(2)

This means find the value of y when x =2

Answer:

Option (1)

Step-by-step explanation:

Sequence has been given as,

[tex]a_n=\frac{n^3+3n}{n^2-6n}[/tex]

[tex]\lim_{n \to \infty}\frac{n^3+3n}{n^2-6n}[/tex]

[tex]=\lim_{n \to \infty}\frac{\frac{n^3+3n}{n^3} }{\frac{n^2-6n}{n^3} }[/tex]

[tex]=\lim_{n \to \infty}\frac{1+\frac{3}{n^2}}{\frac{1}{n}-\frac{6}{n^2} }[/tex]

= ∞

That means with the increase in the value of 'n' sequence gets larger and larger.

Therefore, sequence will diverge.

Option 1 will be the correct option.

Answer:

r ≈ 7.18%

Step-by-step explanation:

a = p(1 + r)^n

-----------------------

a = 10000 * 2 = 20000

p = 10000

n = 2035 - 2025 = 10

Plug in the knowns

20000 = 10000(1 + r)^(10)

Divide both sides by 10000

2 = (1 + r)^(10)

Take the log of both sides

log2 = 10 * log(1 + r)

Divide bot sides by 10

(log2)/10 = log(1 + r)

use calculator

0.030102999566398 = log(1 + r)

antilog both sides

10^0.030102999566398 = 1 + r

1.0717734625 = 1 + r

Subtract 1 from both sides

0.0717734625 = r

r ≈ 7.18%

----------------------------------

Alternate method

2 = (1 + r)^(10)

Take 10th root of both sides

1.0717734625 = 1 + r

Subtract 1 from both sides

0.0717734625 = r

r = 7.18%

Answer:

2x² + 6x + 15 = 0

Step-by-step explanation:

Given quadratic equation is,

-2x² - 6x = 15

We have to convert this equation in the standard form of the quadratic equation,

ax² + bx + c = 0

(-2x² - 6x) = 15

-2x² - 6x - 15 = 0

2x² + 6x + 15 = 0

Using translation concepts, the function whose graph is plotted is given by:

y = 0.5cos(x).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the y-intercept is different of zero, hence it is a cosine function. The amplitude is of 0.5, hence the function is multiplied by 0.5, that is, y = 0.5cos(x), which means that option C is correct.

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

Explanation:

Use the graph to see that the left and right endpoints of the original segment are (2,4) and (6,6) in that order.

Then for each point, we multiply each coordinate by the scale factor 2. This will move the points to the proper location such that the segment is now twice as long as compared to the original.

The left endpoint (2,4) moves to (4,8) after we double the coordinates.

The right endpoint (6,6) moves to (12,12) after we double the coordinates.

The final segment has the left and right endpoints of (4,8) and (12,12) in that order.

Side note: The original and final segments are parallel to one another. This is because both segments share the same slope.
