Answer: To determine Alejandro's earnings for the first 4 weeks, we first need to calculate his weekly pay. To do this, we divide his annual salary by the number of weeks in a year:

Annual salary / 52 weeks/year = weekly pay

$71,500 / 52 weeks/year = $1,375/week

Next, we need to determine the agency fee that Alejandro will pay each week. The agency fee is equal to 40% of the first 5 weeks' pay, so we multiply Alejandro's weekly pay by 40% to get the agency fee:

Weekly pay * 40% = agency fee

$1,375/week * 40% = $550/week

Finally, to determine Alejandro's earnings for the first 4 weeks, we multiply his weekly earnings by the number of weeks:

Weekly pay * number of weeks = earnings

$1,375/week * 4 weeks = $5,500

So, Alejandro will earn $5,500 during the first 4 weeks of his new job, after paying the agency fee each week.

According to the Dietary Guidelines for American 2015, you should limit your fat intake to 25% - 35% of your total calories. The correct option is B.

Food-based dietary guidelines also known as dietary guidelines are intended to serve as a foundation for public food and nutrition policies, health and agricultural policies, and nutrition education programs aimed at promoting healthy eating habits and lifestyles.

Calories are the units of energy released by your body when it digests and absorbs food. The higher the calorie content of a food, the more energy it can provide to your body. When you consume more calories than you require, your body stores the excess calories as fat. Even fat-free foods can be high in calories. In this case, the fay should not be more than 35%.

we want to find the number of hours (or rather days) until only 4.25% of the drives fail.

that means for an exponential distribution we have

P(X < x) = 1 - e^(-Lx)

L = 1/mean = 1/12500

and we need to find x, so that P(X <x) = 0.0425 (that is 4.25% converted into a probability).

so, we get

0.0425 = 1 - e^(-x/12500)

0.0425 - 1 = -e^(-x/12500)

-0.9575 = -e^(-x/12500)

0.9575 = e^(‐x/12500)

ln(0.9575) = -x/12500

-x = ln(0.9575)×12500

x = -ln(0.9575)×12500 = - -0.043429558...×12500 =

The range of the sine function is:

R: {x ∈ R| -1 ≤ x ≤1}

It can also be written as [-1, 1], so that is the correct option.

For a function y = f(x) we define the range as the set of the outputs, this is, the set of the possible values of y.

In this case, our function is y = sin(θ)

Remember that the maximum value of the sine is sin(π/2) = 1

And the minimum is sin(3π/2) = -1

So the maximum value of y is 1 and the minimum is -1, thus, the range is the set of all real numbers between these two, then we can write the range as:

The dimensions of the piece are l = 8 and b =4.

What are dimensions?

The minimal set of coordinates required to specify any point within a mathematical space is the dimension of that space. Because only one coordinate is required to specify a point on a line, it has a dimension of one.

Here,

Let the length of a rectangular piece of metal = l cm

And the breadth of a rectangular piece of metal = b cm

Perimeter of a rectangular piece of metal = 2(l+b) = 24 cm

Or, l+b = 24/2

Or, l+b = 12 -------- (1)

Area of a rectangular piece of metal = l×b = 32 cm²

Or, l×b = 32 ------- (2)

We know that,

(l - b)² = (l+b)² - 4×l×b

(l - b)² = (12)² - 4×32

(l - b)² = 144 - 128

(l - b)² = 16

(l - b)² = 4

l - b = 4 --------- (3)

Adding equations (1) and (3), we get

l+b+l-b = 12 + 4

2l = 16

l = 8

Now, we put the value of l in equation(1) and we get

8 + b = 12

b =4

Hence, the dimensions of the piece are l = 8 and b =4.

Step-by-step explanation:

You have to put in the numbers for the percentages.

The vertex (3, -16) is the maximum point on our quadratic equation.  

When we compare the given Quadratic function with the general form

ax² +bx +c,    

If the value of a is positive then the Quadratic function will have a minimum value, and the graph of the function opens up.  

If the value of a is negative then the Quadratic function will have a maximum value, and the graph of the function opens downwards.  

Here we have

f(x) = -2(x - 5)(x-7)

f(x) = -2 [x²-7x - 5x + 35 ]

f(x) = -2 [x²-12x + 35 ]

f(x) = -2x² + 12x - 35  

Compare f(x) with ax²+ bx + c  

=> a = -2, b = 12, and c = - 35  

Here,

a = -2 is a negative value then the function f(x) will have maximum value    

And the graph of the function opens down.  

The formula for the x coordinate of the vertex = -b/2a  

The coordinate of x = -(12)/2(-2) = 3    

Now substitute x = 3 in f(x) to find y-coordinate

=> f(3) = - 2(3)² +12(3) - 35    

=> f(3) = -2(9) + 36 - 35          

=> f(3) = - 16    

Therefore, y-coordinate = -16            

Therefore,

The vertex (3, -16) is the maximum point of the quadratic equation.

Let n be a positive integer. Consider the  n+1 integers 1,11, 111,1111,... (where the last integer in this list is the integer with n+1 - 1s in its decimal expansion).

Note that there are n possible remainders when an integer is divided by n. Because there are n+1 integers in this list, by the pigeonhole principle there must be two with the same remainder when divided by n. The larger of these integers the smaller one is a multiple of n, which has a decimal expansion consisting entirely of 0s and 1s.

For example, take n=7

we have, 1,11, 111,1111,...,11111111

The remainder possible when any number is divided by 7 is 0,1,2,3,4,5,6

These are the remainders when the numbers in the first list are divided by 7 gives 1,4,6,5,2,0,1,4.

Now you can see that we have 7 pigeonholes {0,1,2,3,4,5,6} and 8 pigeons {1,11, 111,1111,...,11111111} so there needs to be at least one pigeonhole where 2 pigeons will reside.

In this case, we have 11%7=4 and 11111111%7=4

Their difference, i.e. 11111111-11=11111100 is divisible by 7.

To determine the gain or loss on the redemption of the bonds, you need to compare the redemption price to the carrying value of the bonds. The carrying value of the bonds is the amount that the bonds are recorded as being worth on the issuing corporation's balance sheet. This is calculated by adding the Bonds Payable balance and the Premium on Bonds Payable balance.

In this case, the carrying value of the bonds is $810,000 + $8,910 = $818,910. If the bonds are redeemed at a price of $102, the gain or loss on the redemption can be calculated as follows:

Gain or loss on redemption = Redemption price - Carrying value of bonds

= $102 - $818,910

= -$817,810

Since the gain or loss on the redemption is a negative number, this indicates that the redemption price was lower than the carrying value of the bonds, resulting in a loss. The correct answer is therefore: c. $7,290 loss.

So the correct statement is A and D

The relation is:

Is a function, because each element in the domain is mapped to a single element in the range.

A relation maps elements from one set, called the domain, into another set, called the range.

For example, the element x mapped into element y is written as (x, y).

Particularly, a relation is a function if each element from the domain is mapped into only one element of the range.

So, if we had two points like (2, 4) and (2, 5), then the relation is not a function (because the element 2 is mapped into two different elements of the range).

Here the relation is:

(1, 2), (-3, 5), (6, 6), (-2, 0), (1, 2)
