A new bagel store opened. The first day 15 customers entered the store. The number of
customers that enter the store triples each day after. Which function represents f(d), the
number of customers that enter on the d day?
1.
f(d) = 3(15)
2.
f(d) = 3d + 15
3
f(d) = 150 + 3
f(d) = 15(3)
Submit Answer
Answers
Answer:
[tex]f(d) = 15 + 3d[/tex]
Step-by-step explanation:
Given
[tex]a = 15[/tex] --- day 1
[tex]Rate = 3[/tex] -- i.e. triples daily
Required
Determine the function f(d)
The number of customers on a particular day is:
Customers = Day 1 + Rate * Number of days
Represent as a function:
[tex]f(d) = a + Rate* d[/tex]
Where d is the number of days.
So, we have:
[tex]f(d) = 15 + 3* d[/tex]
[tex]f(d) = 15 + 3d[/tex]

Answer:
57.8º
Step-by-step explanation:
According to the law of sines [tex]\frac{sinA}{a}[/tex] = [tex]\frac{sinb}{b}[/tex] = [tex]\frac{sinc}{c}[/tex].
In this triangle we have two sides with two of their angles.
Let's make 8 cm side a with 38º as its angle, and 11 cm side b with x as its angle.
[tex]\frac{sinx}{11}[/tex] = [tex]\frac{sin38}{8}[/tex]
Now we multiply both sides by 11 to get rid of the denominator on the left.
sinx = [tex]\frac{11sin38}{8}[/tex]
To find x, we use inverse sine.
x = sin⁻¹ (11sin38/8)
Plug this into a calculator, and you will get 57.837.
Round this to 57.8º
Hope this helps!

Use the x-intercept method to find all real solutions of the equation.
x? - 7x2 + 4x + 12 = 0
Answers
Correct equation is;
x³ - 7x² + 4x + 12 = 0
Answer:
All the real solutions are -1, 2 and 6
Step-by-step explanation:
The x-intercept of x³ - 7x² + 4x + 12 = 0 will occur where y is zero. This is where the curve crosses the x-axis on the graph of this function.
Now, I have plotted a graph of this function and attached it.
From the attached image, the curve crosses the x - axis at the points, x = -1, x = 2, x = 6.
Therefore all the real solutions are -1, 2 and 6

Answers
Answer:
Frank's pet store
Step-by-step explanation:
Assuming they want the most fish with 12 gallons, lets see how many we can get from each place
Sally's. 12/4 = 3

Franks. 12/3 = 4
4* 4 = 16.

Answer:
y +2 = -1/2(x -7)
Step-by-step explanation:
The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...
m = rise/run = 6/3 = 2
A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...
-1/m = -1/2
We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
An equation for the desired line is ...
y +2 = -1/2(x -7)

This can be rearranged to other forms.
y = -1/2x +3/2 . . . . . slope-intercept form

Answer:
The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]
Step-by-step explanation:
Cosine is is calculated as adjacent over hypotenuse. The line adjacent to A is 3 in length.
So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator
[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]

Mei wants to solve the inequality --W < 12. How can she isolate the variable?
2
• Multiply both sides by -2 and reverse the inequality symbol.
• Multiply both sides by -2 and do not reverse the inequality symbol.
*) Divide both sides by 12 and reverse the inequality symbol.
) Divide both sides by 12 and do not reverse the inequality symbol.
Answers
Answer:
Multiply both sides by -2 and reverse the inequality symbol.
Step-by-step explanation:
To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2
When multiplying or dividing by negatives, you must reverse the inequality symbol as well.
To isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.
Isolating variables in inequalityIsolation of variables means making the variable the subject of the formula from the given expression.
Given the inequality expression -1/2 w < 12
To make w the subject of the formula, we will have to multiply both sides by -2 to have;
-1/2 w * -2 > 12 * -2
w > -24
Hence to isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.

p(4) = 64 - 17*16 + 196 - 833
p(4) = 64 - 272 - 637
p(4) = -208 - 637

Answers
Answer:
The answer is below
Step-by-step explanation:
We are asked to create a box plot. To create a box plot, we need to determine the minimum point, maximum point, lower quartile, upper quartile, interquartile range, median.
First we have to arrange the data in ascending order. This gives:
85, 150, 180, 200, 210, 250, 450
The minimum point = 85
The maximum = 450
[tex]Median=\frac{2}{4}(n+1)^{th}term=\frac{2}{4}(7+1)=4^{th}\ term=200\\\\Median=200 \\\\Lower\ quartile(Q_1)=\frac{1}{4}(n+1)^{th}term=\frac{1}{4}(7+1)=2^{nd}\ term=150\\\\Lower\ quartile(Q_1)=200 \\\\Upper\ quartile(Q_3)=\frac{3}{4}(n+1)^{th}term=\frac{3}{4}(7+1)=6^{th}\ term=250\\\\Upper\ quartile(Q_3)=250 \\\\Interquartile\ range=Q_3-Q_1=250-150=100[/tex]
