Evaluate the expression when c=4. c2 +6c+8

(the 2 after the c is one of those mini high 2's.)​

Answer: -2

Step-by-step explanation:

Slope=rise/run

In this case we rise up 4

And we run 2 to the left which makes it a negative

So in this case the slope is -4/2

Which can be simplified to -2

-9 - (-4) is the same as -9 + 4 because subtracting a negative is the same as addition. I'm not quite sure how to represent it with the integer chip model, but basically, taking away -4 from -9 is the same as adding positive 4 to -9.

Perhaps draw the 9 negative chips and place the four negative chips under it, then cross out those that correspond to show that it is increasing in sum?

the answer is A. {-1, 1, 3}

Step-by-step explanation:

Answer: 0ft < X ≤ 5.73ft

Step-by-step explanation:

In this case, we have a rectangle.

For a rectangle of length L and width W, the area is:

A = L*W.

And we have:

L = X

W = X  + 3ft.

Then the area will be:

A = X*(X + 3ft) = X^2 + 3ft*X.

And we want to have a maximum area of 50ft^2.

Then we can write:

A = X^2 + 3ft*X ≤ 50ft^2

Now let's solve this for X.

Now, the first thing we can see is that both coefficients in our quadratic equation are positive, so as the absolute value of X increases, also does the whole equation.

Then makes sense start for the upper limit of X, this is when:

X^2 + 3ft*X = 50ft^2.

Now we can solve the quadratic equation:

X^2 + 3ft*X - 50ft^2 = 0

Applying the Bhaskara formula, the solutions are:

[tex]X = \frac{-3ft +- \sqrt{(3ft)^2 - 4*1*(-50ft^2)} }{2} = \frac{-3ft +-14.46ft }{2}[/tex]

Then we have two solutions:

X = (-3ft - 14.46ft)/2 = -8.73 ft.

X = (-3ft + 14.46ft)/2 = 5.73 ft

Because X represents a distance, it can only be positive, then we must select the option X = 5.73ft.

This is the maximum value of X, and we will have:

0ft < X ≤ 5.73ft

Where the lower limit is there because we can not have X = 0ft, as this does not have physical meaning.

Answer:

120 feet

Step-by-step explanation:

Given that the submarine started at the surface of the water and collected data at three different depths.

As each time the submarine dove 40 feet down, so,

the depth covered in one dive = 40 feet.

From the surface, the depth covered in 1 drive, [tex]d_1= 40[/tex] feet

Similarly, the total depth covered in 2 drive, [tex]d_2 = 2\times 40= 80[/tex] feet.

So, for any integer [tex]n[/tex], the depth covered in [tex]n[/tex] drive,

[tex]d_n=40n[/tex]

This is the required integer equation to model the situation.

Since, for three different depths, there must be 3 drive and the submarine will be at the lowest depth after 3rd dive.

So, for the lowest depth, n=3

Hence, the lowest depth = 40x3= 120 feet.

Answer: 1,2, 5

Step-by-step explanation:

The amount of daylight fluctuates between 4.5 between least to greatest, and the graph required 3 months of horizontal shift compared to the parent function y = sin x, and the greatest number of sunlight can be 14.5 hours, so options A, B, and E are correct.

The middle number, which is obtained by dividing the sum of all the numbers by the variety of numbers, is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.

Given:

The average number of daylight hours, y, in a month for a particular city over the course of a 12-month year can be determined using the equation

y = 2.375 sin [(π / 6)x - π / 2]+ 12.125,

Calculate the greatest number of daylight as shown below,

y = 2.375 sin[30 - 90] + 12.125

y = 14.5 hours

Hence, the greatest number of sunlight can be 14.5 hours,

Answer:

(4, -5)

Step-by-step explanation:

(4, 5) is 4 units to the right of the y-axis and 5 units above the x-axis.

When you reflect point (4, 5) over the x-axis, the new point is still 4 units to the right of the y-axis, so its x-coordinate is still 4. The distance that was above the x-axis now is below the x-axis, so the y-coordinate is -5.

John has two coupons to use at a clothing store. One is for $20 off and the other is for 20% off. John wants to purchase a shirt with one of the coupons and wants to pay the least amount that he can. Choose the answer that BEST describes the situation. * 1 point A. The shirt will have the lowest price with the $20 off coupon. B. The shirt will have the lowest price with the 20% off coupon. C. The shirt will cost the same with either coupon. D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.

Answer: D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.

Step-by-step explanation:

Given two different coupon options :

First: 20% off

Second = $20 off

To our hase with one which enables one to pay the amount of money :

The price of the shirt will determine which of the coupons will give the least amount. For instance, a shirts which which cost below $100 will require the $20 off coupon in other to attain the least payment amount. However for shirts which cost above $100, the 20% coupon yield the least amount. Shirts which cost $100. Both coupons yields the same discount amount.

Answer:

There are 72 cal in 2/3 cup serving of noodle soup

Step-by-step explanation:

The given parameters are;

The amount of calories in 3/4 cup serving of chicken noodle soup = 81 cal

The amount of calories in a 2/3 cup serving is given as follows;

3/4 cup contains 81 cal

1 cup contains 81/(3/4) cal = 81 × 4/3 cal = 108 cal

1 cup contains 108 cal

2/3 cup contains = 2/3 × 1 cup = 2/3 × 108 cal = 72 cal

2/3 cup contains 72 cal

Therefore, there are 72 cal in 2/3 cup serving of noodle soup.

The graphs which represents someone driving away from their house and having to stop for a stoplight at the corner is graph (IV)

A graph is a line straight or curved that shows relation between two quantities out of which one varies as a result of change in other.

To make it clear let us consider we have two variables x and y where,

y=2x

The variable that is made to alter or change is called the independent variable. Here in our case x is an independent variable. Another variable that varies as a result of the change in the independent variable is called the dependent variable.

Here  y  is the dependent variable whose value changes with change in the value of  x.

As, from the situation someone driving away from their house then the distance will increase which is shown as the rising line of the graph.

Now,  stop for a stoplight at the corner then to stop the car the speed should be decrease which tends to zero which is shown by the down line in the graph.

Hence, the  graphs which represents someone driving away from their house and having to stop for a stoplight at the corner is graph (IV)

Answer: f ^− 1 ( x ) = x /7+ 9/ 7

Step-by-step explanation:

Replace  f ( x )  with  y .

y = 7 x− 9

Interchange the variables.

x = 7 y − 9

solve for y

y = x/ 7 + 9 /7

Solve for  y  and replace with  f ^− 1 ( x ) .

f ^− 1 ( x ) = x /7+ 9/ 7

Answer:

[tex]y=\frac{5}{8}x-5[/tex]

Step-by-step explanation:

You're given two points, using that you can use the slope-finding formula:

[tex]slope=\frac{(y^{2} - y^{1}) }{(x^{2} - x^{1})}[/tex]

After that, match up the y-coordinates with each other and the same goes for the x-coordinates. It should look something like this:

[tex]slope = \frac{(0-(-5))}{(8-0)} \\\\=\frac{5}{8}[/tex]

5/8 is your slope. Using the general slope formula y=mx + b, you know that m is the slope and b is the y-intercept. So now you know your slope, plug it into the formula, along with one of the given points. In this case, I will be using (8, 0) because it is easier to solve.

[tex]m = \frac{5}{8}\\ \\y = (\frac{5}{8} )x+b\\(8, 0)\\(0) = \frac{5}{8}(8) + b\\ 0 = 5 + b\\\\-5 =b\\ \\y=\frac{5}{8}x-5[/tex]

You can see I replaced the x and y with the given values accordingly. Then you simplify by subtracting the five on both sides and your y-intercept is -5. Then combine your slope and y-intercept to get your answer!
