56 times a number minus 13 is equal to 6 less than the number.
Step 1 of 2: Write out the equation.
Answer:
The equation is 56x - 13 = x - 6
Step-by-step explanation:
Let's say our 'number' is x. If it says it's 56 times our number, it's 56x. Minus 13, which is 56x - 13. If it is equal than 6 less than the number, then it is x - 6.
So the equation is 56x - 13 = x - 6
Given the feasible region graphed below, where will the maximum value of the objective function f(x, y) = −2x + y − 1 occur?
a. (3, 0)
b. (−3, 0)
c. (0, −3)
d. (0, 0)
The maximum value of the objective function occurs at (-3, 0). The correct option is (-3, 0).
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) and x ∈ X and y ∈ Y.
The objective function is given as f(x, y) = −2x + y − 1.
For the maximum value all the options are analysed one by one as follows,
(a) Substitute x = 3 and y = 0 in the given objective function to obtain,
-2 × 3 + 0 - 1 = -7
(b) Substitute x = -3 and y = 0 in the given objective function to obtain,
-2 × -3 + 0 - 1 = 5
(c) Substitute x = 0 and y = -3 in the given objective function to obtain,
-2 × 0 + -3 - 1 = -4
(d) Substitute x = 0 and y = 0 in the given objective function to obtain,
-2 × 0 + 0 - 1 = -1
Hence, the maximum value of the given objective function occurs at (-3, 0).

The Antique Auto News charges $10 for a 10-word classified ad. Each additional word costs $0.40. For an extra $40, a seller can include a photo in the ad. How much would a 20-word ad with a photo cost?
Answer: $60
Step-by-step explanation:
Here is why:
For 20 -word ad it will be $20 because of twice the amount of the 10 word amount. and another $40 for the photo!
And you get $60!
Any Questions
It will cost $54 for an 20 word ad and a photo.
We have Antique Auto News agency which charges $10 for a 10-word classified ad. Each additional word costs $0.40 and for an extra $40, a seller can include a photo in the ad.
We have to determine much would it cost for a 20-word ad with a photo.
Starting from x, if the bacteria count rises by 5 every second, then determine the formula to calculate the bacteria count after 30 seconds.Initial count = x
Count increasing per second = 5
Assume that the bacteria count after t seconds is y. Then -
y = x + 5t
for t = 30 ↔ y = 150 + x
According to the question, we have -
Cost of 10-word classified ad → $10
Additional word cost → $0.40
Additional Photo cost → $40
Therefore -
Assume that for a 20-word ad with a photo costs $x.
Therefore -
x = 10 + 0.40 x 10 + 40
x = 10 + 4 + 40
x = 54
Hence, it will cost $54 for an 20 word ad and a photo.

small prism dimensions: 60 x 30 x 40 = 72,000

3. To make sure the sweater she is knitting will be the right size, Gale knits a sample that is 2 inches long. She knits a second sample that is 14 times as long as the first sample. How many inches long is the second sample?
please help, will mark u brainliest plz plz plz
Hello and good day.
For this question you will use multiplication.
We know that the first same is 2 inches long and the second sample is 14 times long as the first sample.
When some thing says times, it uses multiplication, especially when mentioned in word problems.
So 14 times 2 = 28.
The answer is: The second sample is 28 inches.

Marine biologists have determined that when a shark detectsthe presence of blood in the water, it will swim in the directionin which the concentration of the blood increases mostrapidly. Based on certain tests in seawater, theconcentration of blood(in parts per million) at point P(x,y) on thesurface is approximated by:
C(x,y)= e^- (x^2+2y^2).10^4
where x and y are measured in meters in a rectangularcoordinate system with the blood source at the origin.
a. Identify the level curves of the concentration function andsketch several members of this family together with a path that ashark will follow to the source.
b. Suppose a shark is at the point (xo, yo) when it first detects the presenceof blood in the water. Find an equation of the shark's path bysetting up and solving a differential equation.
Solution :
a). The level curves of the function :
[tex]$C(x,y) = e^{-(x^2+2y^2)/10^4}$[/tex]
are actually the curves
[tex]$e^{-(x^2+2y^2)/10^4}=k$[/tex]
where k is a positive constant.
The equation is equivalent to
[tex]$x^2+2y^2=K$[/tex]
[tex]$\Rightarrow \frac{x^2}{(\sqrt K)^2}+\frac{y^2}{(\sqrt {K/2})^2}=1, \text{ where}\ K = -10^4 \ln k$[/tex]
which is a family of ellipses.
We sketch the level curves for K =1,2,3 and 4.
If the shark always swim in the direction of maximum increase of blood concentration, its direction at any point would coincide with the gradient vector.
Then we know the shark's path is perpendicular to the level curves it intersects.
b). We have :
[tex]$\triangledown C= \frac{\partial C}{\partial x}i+\frac{\partial C}{\partial y}j$[/tex]
[tex]$\Rightarrow \triangledown C =-\frac{2}{10^4}e^{-(x^2+2y^2)/10^4}(xi+2yj),$[/tex] and
[tex]$\triangledown C$[/tex] points in the direction of most rapid increase in concentration, which means [tex]$\triangledown C$[/tex] is tangent to the most rapid increase curve.
[tex]$r(t)=x(t)i+y(t)j$[/tex] is a parametrization of the most [tex]$\text{rapid increase curve}$[/tex] , then
[tex]$\frac{dx}{dt}=\frac{dx}{dt}i+\frac{dy}{dt}j$[/tex] is a tangent to the curve.
So then we have that [tex]$\frac{dr}{dt}=\lambda \triangledown C$[/tex]
[tex]$\Rightarrow \frac{dx}{dt}=-\frac{2\lambda x}{10^4}e^{-(x^2+2y^2)/10^4}, \frac{dy}{dt}=-\frac{4\lambda y}{10^4}e^{-(x^2+2y^2)/10^4} $[/tex]
∴ [tex]$\frac{dy}{dx}=\frac{dy/dt}{dx/dt}=\frac{2y}{x}$[/tex]
Using separation of variables,
[tex]$\frac{dy}{y}=2\frac{dx}{x}$[/tex]
[tex]$\int\frac{dy}{y}=2\int \frac{dx}{x}$[/tex]
[tex]$\ln y=2 \ln x$[/tex]
⇒ y = kx^2 for some constant k
but we know that [tex]$y(x_0)=y_0$[/tex]
[tex]$\Rightarrow kx_0^2=y_0$[/tex]
[tex]$\Rightarrow k =\frac{y_0}{x_0^2}$[/tex]
∴ The path of the shark will follow is along the parabola
[tex]$y=\frac{y_0}{x_0^2}x^2$[/tex]
[tex]$y=y_0\left(\frac{x}{x_0}\right)^2$[/tex]

First USA, a major credit card company, is planning a new offer for their current cardholders. The offer will give double airline miles on purchases for the next 6 months if the cardholder goes online and registers for the offer. To test the effectiveness of the campaign, First USA recently sent out offers to a random sample of 50,000 cardholders. Of those, 1184 registered. Give a 95% confidence interval for the true proportion of those cardholders who will register for the offer.
Answer:
The answer is "[tex]0.02235 \ and \ 0.02501[/tex]".
Step-by-step explanation:
Given:
[tex]x= 1184\\\\n = 50000\\\\c = 95\% = 0.95[/tex]
The sample proportion is computed by subtracting that sample size by both the successes:
[tex]\hat{p}=\frac{x}{n} =\frac{1184}{50000}= 0.02368[/tex]
Determine [tex]z_{\frac{\alpha}{2}} = Z_{0.025}[/tex] using table Z in Table Z for trust level [tex]1 -\alpha = 0.95[/tex]
add using appendix F ((0.025) inside the table, therefore the z-score is the found z-score with negative sign):
So, the boundaries of the confidence interval:
[tex]\to \hat{p}-z_{\frac{\alpha}{2}} \cdot \sqrt{\frac{\hat{p} (1-\hat{p})}{n}} = 0.02368 - 1.96 \cdot \sqrt{\frac{0.02368(1-0.02368)}{50000}}\approx 0.02235 \\\\\to \hat{p}-z_{\frac{\alpha}{2}} \cdot \sqrt{\frac{\hat{p} (1-\hat{p})}{n}} = 0.02368 + 1.96 \cdot \sqrt{\frac{0.02368(1-0.02368)}{50000}}\approx 0.02501\\\\[/tex]

Step-by-step explanation:
No denominator is allowed to be zero. 'c' and 'd' are in the denominator of the numerator and denominator terms. 'a' and 'b' are in the numerator of the denominator term, so will make that term zero if they are zero. In short, none of a, b, c, or d may be zero.
