Cam's Cupboard grocery store is having a sale on canned goods. Tiana decides to stock up
and purchases 12 cans of soup. During the sale, cans of soup sell for $0.55 les than full
price. Tiana pays a total of $13.20 for the cans of soup.
Which equation can you use to find the amount, f, each can of soup costs at full price?
0.55(f - 12) = 13.20
12(f - 0.55) = 13.20
0.55f - 12 = 13.20
12f - 0.55 = 13.20
How much does each can of soup cost at full price?

Answer:

45,40,35,30,25,20,15...

Step-by-step explanation:

The common difference equals:

-5

The sum of the sequence equals:

150

The explicit formula of this sequence is:

a_n=45+(n-1)*(-5)

The recursive formula of this sequence is:

a_n=a_((n-1))-5

The nth terms:

45,40,35,30,25,20,15...

Answer:

the anser is 0

this is an additive inverse property.

Step-by-step explanation:

Isolating the absolute value term, we find

|x| + 5 ≤ 1   ⇒   |x| ≤ -4

However, the absolute value function maps every number x to a non-negative number, so |x| ≤ -4 is impossible and there is no solution to the inequality.

Answer:

1548 unit^2

Step-by-step explanation:

The area each of the 2 bases

= width * height

=  17 * 12

= 204 unit^2

2 have area 408 unit^2

Area of the lateral rectangles = 2 * 13 * 19 = 494 unit^2

Area of the top and bottom  rectangles = 2 * 17 * 19 = 646 unit^2

Total surface area = 408 + 494 + 646

= 1548 unit^2.

Answer: -10x³ - 6x - 6

Step-by-step explanation:

      f(x) -g(x) means we will subtract g(x) from f(x)

Given:

   (-8x³ + 1) - (2x³ + 6x + 7)

Distribute the negative:

   -8x³ + 1 - 2x³ - 6x - 7

Combine like terms, simplify:

   -10x³ - 6x - 6

         f(x) -g(x) is -10x³ - 6x - 6

Answer:

[tex]-10x^{3} -6x-6[/tex]

Step-by-step explanation:

The question is asking us to find f(x) - g(x). In the question it also gives the values of each as:

f(x) = [tex]-8x^{3} +1[/tex]

g(x) = [tex]2x^{3} +6x+7[/tex]

To find the answer, plug both of these values into f(x) - g(x):

([tex]-8x^{3} +1[/tex])-([tex]2x^{3} +6x+7[/tex])           Lets distribute the negative to [tex]2x^{3} +6x+7[/tex].

[tex]-8x^{3} +1[/tex] - [tex]2x^{3}-6x-7[/tex]             Combine like terms

[tex]-10x^{3} -6x-6[/tex]

Therefore, the final answer for f(x) - g(x) is equal to [tex]-10x^{3} -6x-6[/tex].

Considering the parabolic equation, the equation for the directrix is given by x = 4.9375.

The equation of a horizontal quadratic function, of vertex (h,k), is given by:

(y - k)^2 = 4p(x - h)

The directrix is given by:

x = h - p.

In this problem, the equation is given by:

(y - 2)² = 0.25(x - 5).

Hence h = 5, p = 0.25/4 = 0.0625, hence the directrix is:

x = h - p = 5 - 0.0625 = 4.9375.

The time taken by the rock to reach the lake below is 5.123 sec

t= 5.123 sec

A quadratic equation is an algebraic expression of the second degree in x. The quadratic equation in its standard form is [tex]ax^{2} +bx+c=0[/tex] where a, b are the coefficients, x is the variable, and c is the constant term.

It is given that,

H= [tex]-16t^{2} +32t+256[/tex], which represent the height of the rock

Also, we have given that the height of the cliff is 256 feet.

Now to find the time taken by the rock, take H=0

[tex]-16t^{2} +32t+256[/tex]=0

[tex]-16(t^{2} -2t-16) = 0[/tex]

[tex]t^{2} -2t-16 = 0[/tex]

[tex]t= \frac{-(b)\pm\sqrt{(b)^{2}- 4 *a*c } )}{2*a}[/tex]

From above equation, a=1, b=-2, c=-16

So,

[tex]t= \frac{-(-2)\pm\sqrt{(-2)^{2}- 4 *1*(-16) } )}{2*1}[/tex]

[tex]t= \frac{2\pm\sqrt{(4+64 } )}{2}[/tex]

[tex]t= \frac{2\pm\sqrt{(68 } )}{2}[/tex]

There will be two value one with positive [tex]t= -2+\sqrt{(68 } )[/tex] and another with negative [tex]t= -2-\sqrt{(68 } )[/tex]

We will neglect negative value because time can't be negative.

[tex]t= \frac{2+\sqrt{(68 } )}{2}[/tex]

[tex]t= \frac{2+8.246}{2}[/tex]

[tex]t= \frac{10.246}{2}[/tex]

t= 5.123 sec

The time taken by the rock to reach the lake below is t= 5.123 sec

The line graph (C) represents the data representation on the line plot option (C) is correct.

A line graph is a graph made up of segments of straight lines that connect the depicted data points.

We have data shown in the table:

The data set value 11 repeated two times, so two dots we will see on the line plot.

The data set value 11(1/2) repeated one time, so one dot we will see on the line plot.

The data set value 11(3/4) repeated two times, so two dots we will see on the line plot.

The data set value 12 repeated two times, so two dots we will see on the line plot.

Similarly, we can check for others.

Thus, the line graph (C) represents the data representation on the line plot option (C) is correct.
