from 2001 to 2012 the sales for a local doughnut store increased by about the same percent each year. The sales, S, for year t can be modeled by, S=372,300(6/5)^t. Where t=0 corresponds to 2001. What were the sales in 2001

Answers

Using the given exponential function, it is found that the number of sales in 2001 was of 327,300.

What is the exponential function in this question?

It models the number of sales S in t years after 2001, given by:

[tex]S(t) = 372300\left(\frac{6}{5}\right)^t[/tex]

2001 is year 0, hence the amount is given by S(0), that is:

[tex]S(0) = 372300\left(\frac{6}{5}\right)^0 = 372300[/tex]

The number of sales in 2001 was of 327,300.

What is the slope of the line?

Answers

Answer:

-3

Step-by-step explanation:

First, let's remind ourselves the definition of a slope.

Slope = rise/run OR the height from one point to another/ the distance from one point to another.

First, let's find two points on this graph that are marked easily.

One point that can be found is (0, -3) and the other is (0, -1).

Let's apply our formula to these points!

<------- Starting from point (0, -3), we are RISING 3 points and RUNNING -1 points.

Rise 3

------- = ----------

Run -1

3/-1 = -3

The slope of the line is -3.

Answer:

-3.

Step-by-step explanation:

1) to choose two points on the given line on the graph. For example, A(-2;3) and B(-1;0);

2) to calculate the required slope according to the rule:

[tex]slope=\frac{Y_B-Y_A}{X_B-X_A};[/tex]

3) the required slope:

slope=-3/1=-3.

If S and T are mutually exclusive events, find P(S or T),

Answers

Answer:

P(S ∪ T) = 3/4

Step-by-step explanation:

Given:

P(S) = 5/8P(T) = 1/8

For mutually exclusive events S and T,

P(S ∪ T) = P(S) + P(T)

Therefore,

P(S ∪ T) = (5/8) + (1/8)

Draw the image of quadrilateral ABCD under a translation by 2 units to the left and 3 units up.

Answers

The image of the quadrilateral after the translation is added as an attachment

How to determine the image of the quadrilateral?

The given parameter represents the quadrilateral ABCD on the graph.

On this graph, we have the coordinates of ABCD to be:

A = (2, -3)

B = (-1, 3)

C = (-1, -3)

D = (-4, -4)

The translation is given as

2 units to the left and 3 units up.

Mathematically, this can be represented as

(x, y) = (x - 2, y + 3)

So, we have

A' = (0, 0)

B = (-3, 6)

C = (-3, 0)

D = (-6, -1)

Next, we plot the above coordinates on the graph (See attachment)

Answers

f(x)=|x|

Find vertex

f(0)=(0)

(0,0) is the vertex

The graph shifted 3 units right.

So new translation

g(x)=|x-3|

Find y intercept

g(0)=|-3|=3

But it's at (0,1) approximately

So compression factor

Now last equation

g(x)=1/3|x-3|Accurate one

Take (-4,2)

Find value

g(-4)=|-7|=7

So compression factor

So accurate equation is

1/3.5|x-3|

Answer:

[tex]g(x)=\dfrac{2}{7}|x-3|[/tex]

Step-by-step explanation:

Translations

For [tex]a > 0[/tex]

[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]

[tex]y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis by a factor of}\:a[/tex]

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

Parent function: [tex]f(x)=|x|[/tex]

The vertex of the parent function is at (0, 0) as [tex]f(0)=|0|=0[/tex]

From inspection of the graph, the vertex of the transformed function is at (3, 0). Therefore, there has been a translation of 3 units right:

[tex]\implies g(x)=f(x-3)=|x-3|[/tex]

(There has not been any vertical translation since the y-value of the vertex of the parent function and the translated function is the same)

From inspection of the graph, we can see that it has been stretched parallel to the y-axis:

[tex]\implies g(x)=a\:f(x-3)=a|x-3|[/tex]

The line goes through points (10, 2) and (-4, 2).

Substituting one of these points to find a:

[tex]\implies a|10-3|=2[/tex]

[tex]\implies 7a=2[/tex]

[tex]\implies a=\dfrac{2}{7}[/tex]

Therefore,

[tex]g(x)=\dfrac{2}{7}|x-3|[/tex]

Darren is making veggie burgers for his family. He will use all the burgers mix he made to form 4 burgers of equal weight. The recipe only makes 32 oz burger mix but Darren made more than that to make extra big burgers

Answers

Answer:

4 > 32

Step-by-step explanation:

The variable x represents how much each of Darren's burgers will weigh. Since he will form 4 burgers of equal weight, the expression 4x represents the total weight of the burgers.

And, since Darren will use more than 32 ounces of burger mix, 4x must be greater than 32.

This inequality shows the relationship.

4x > 32

Now, solve for x.

4x > 32

4x/4 32/4

divide 32 by 4

So the answer is x > 8

Hello, precalc, need help on finding csc

Answers

Recall the double angle identity for cosine:

[tex]\cos(2x) = \cos^2(x) - \sin^2(x) = 1 - 2 \sin^2(x)[/tex]

It follows that

[tex]\sin^2(x) = \dfrac{1 - \cos(2x)}2 \implies \sin(x) = \pm \sqrt{\dfrac{1-\cos(2x)}2} \implies \csc(x) = \pm \sqrt{\dfrac2{1-\cos(2x)}}[/tex]

Since 0° < 22° < 90°, we know that sin(22°) must be positive, so csc(22°) is also positive. Let x = 22°; then the closest answer would be C,

[tex]\csc(22^\circ) = \sqrt{\dfrac2{1-\cos(44^\circ)}} = \sqrt{\dfrac2{1-\frac5{13}}} = \dfrac{\sqrt{13}}2[/tex]

but the problem is that none of these claims are true; cot(32°) ≠ 4/3, cos(44°) ≠ 5/13, and csc(22°) ≠ √13/2...

How to find a proportion in a t-distribution?

The proportion is found using a calculator, with three inputs:

The tail of the test, if it is left, right, or two-tailed.The test statistic.The amount of degrees of freedom.

In this problem, we have a left-tailed proportion, as we want the proportion that is less than a value, with test statistic t = -1.4 and 30 + 40 - 2 = 68 df, hence the proportion is of 0.083.

The area of each small triangle is:

Area = 0.5 square unit

Step-by-step explanation:

[tex]\begin{aligned}\implies (\sin A)(\cos A)(\tan A)& =(\sin A)(\cos A)\dfrac{(\sin A)}{(\cos A)}\\\\& =\dfrac{(\sin A)(\cos A)(\sin A)}{(\cos A)}\\\\& =\sin^2 A\\\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Trig identity}: \quad \sin^2 A + \cos^2 A &=1\\\implies \sin^2 A & =1-\cos^2 A\end{aligned}[/tex]

The value of the expression (sin A)(cos A)(tan A) is equivalent to[tex]1 - k^2[/tex], which corresponds to option 4). k².

How to determine the value of the expression (sin A)(cos A)(tan A) is equivalent

Let's use the trigonometric identity: tan A = (sin A) / (cos A).

Given cos A = k, we can find sin A using the Pythagorean trigonometric identity:[tex]sin^2 A + cos^2 A = 1.[/tex]

[tex]sin^2 A + k^2 = 1[/tex]

[tex]sin^2 A = 1 - k^2[/tex]

sin A = √(1 - [tex]k^2[/tex])

Now, the expression (sin A)(cos A)(tan A) is:

(sin A)(cos A)(tan A) = (√(1 - [tex]k^2[/tex]))(k)((√(1 -[tex]k^2[/tex]))/k)

Now, we can cancel out the common terms:

(sin A)(cos A)(tan A) = (√(1 - [tex]k^2[/tex]))(√(1 - [tex]k^2[/tex]))

Taking the square root of the product:

(sin A)(cos A)(tan A) = √((1 -[tex]k^2[/tex])(1 - [tex]k^2[/tex]))

(sin A)(cos A)(tan A) = √((1 -[tex]k^2[/tex][tex])^2[/tex]

(sin A)(cos A)(tan A) = [tex]1 - k^2[/tex]

So, the value of the expression (sin A)(cos A)(tan A) is equivalent to [tex]1 - k^2[/tex], which corresponds to option 4). k².

Jerry is running a race. He knows he can run 44 feet in 3 seconds. If he maintains this rate, how many miles will he run in 1 hour?

Answers

Step-by-step explanation:

44 ft in 3 seconds

in 1 hour there are 60 minutes with 60 seconds each.

so, 1 hour = 60×60 = 3600 seconds.

in 3600 seconds there are

3600 / 3 = 1200 "packages" of 3 seconds.

so, Jerry would run

1200 × 44 = 52800 ft in 1 hour.

there are 5280 ft in 1 mile.

that means Jerry would run

52800 / 5280 = 10 miles in 1 hour.

Step-by-step explanation:

these are super simple to solve if you break it down! in order to turn a mixed number into an improper fraction, you first need to multiply the whole number by the denominator of the fraction. then, you add the numerator of the fraction to the product of the multiplication problem. that answer is then the new numerator of the fraction! the denominator will stay the same.
