Giselle pays $210 in advance on her account at the athletic club. Each time she uses the club, $15 is deducted from the account. Model the situation with a linear function.
A. b = 195 – 15x
B. b = 210 – 15x
C. b = 195 + 15x
D. b = 210 + 15x
Answer:
B is correct. Your starting amount is 210$ And you're taking away 15$ each time she uses the club,x.
Step-by-step explanation:
Answer:
The linear function model the situation is b = 210 - 15x .
Option (B) is correct .
Step-by-step explanation:
Let us assume that the number of times giselle uses the club be x .
As given
giselle pays $210 in advance on her account at the athletic club.
Each time she uses the club,$15 is deducted from the account.
Let suppose that the money left after giselle uses the club x times is b .
Than the equation becomes
Money left = Amount pay in advance - Deducted amount × Number of times giselle uses the club .
Put all the values in the above
b = 210 - 15 × x
b = 210 - 15x
Therefore the linear function model the situation is b = 210 - 15x .
Option (B) is correct .
A right square prism has a volume of 75 cubic inches. The prism is enlarged so its height is increased by a factor of 5, but the other dimensions do not change. What is the new volume? A. B. C. D.
Answer:
The new volume is 375 cubic inches.
Step-by-step explanation:
Volume of a right square prism:
The volume of a right square prism is given by:
[tex]V = a^2h[/tex]
In which a is the length of the edge and h is the height.
A right square prism has a volume of 75 cubic inches.
This means that:
[tex]a^2h = 75[/tex]
The prism is enlarged so its height is increased by a factor of 5
Edge is the same, height is 5 times. So
[tex]a^2(5h) = 5(a^2h) = 5*75 = 375[/tex]
The new volume is 375 cubic inches.

Drag each inequality to the correct location on the table based on whether its
graph will have a dashed or a solid boundary line.
Answer:
y>2x+8: Dashed x+1/2y is less than or equal to 12: Solid y is greater than or equal to 2/3x-6: Solid -4x+2y<10: Dashed
Step-by-step explanation:
If there is a < or > sign, it is dashed, because the answer you get is not part of the solution (it is either less than or greater than the solution). If it is a less than or greater than or equal to sign (with the line under it) the line will be solid because the answer you get is part of the solution.
The boundary line will not be included in the solution set. Therefore, the boundary line will be dashed. The table shows the following:
Dashed if the boundary line is not included in the solution set.
Solid if the boundary line is included in the solution set.
The inequalities that will have a dashed boundary line are:
y > 2x + 5
x + y ≤ 12
The inequalities that will have a solid boundary line are:
y ≤ 2x - 6
-4x + 2y - 10 ≤ 0
Here is an explanation of why each inequality will have the boundary line that it does:
y > 2x + 5
This inequality is not equal to 2x + 5, so the boundary line will not be included in the solution set. Therefore, the boundary line will be dashed.
x + y ≤ 12
This inequality is equal to x + y ≤ 12, so the boundary line will be included in the solution set. Therefore, the boundary line will be solid.
y ≤ 2x - 6
This inequality is equal to y ≤ 2x - 6, so the boundary line will be included in the solution set. Therefore, the boundary line will be solid.
-4x + 2y - 10 ≤ 0
This inequality is not equal to -4x + 2y - 10, so the boundary line will not be included in the solution set. Therefore, the boundary line will be dashed.

Amelia, recuerda que se ha propuesto no consumir más de 260Cal (Calorías) en su desayuno.
Si Amelia se sirve una taza de agua tibia echándole 3 cucharaditas de Nesquik y una cucharadita de azúcar (17 Cal). También va a comer un pan integral (180 Cal).
¿Cumplirá Amelia con lo que se ha propuesto? Explica.
Answer:
¿Cumplirá Amelia con lo que se ha propuesto?
Amelia no cumple con lo que se ha propuesto, porque:
56,4 ÷ 2 = 28,2 ← 1 cucharadita
28,2 + 28.2 = 56,4 + 28,2 = 84.6 Cal ← 3 cucharaditas
84.6 Cal + 17 Cal azúcar = 101,6 Cal
101,6 Cal + 180 Cal pan = 281,6 Cal
Lo que se ha propuesto Amelia = 260 Cal
Lo que está consumiendo = 281 Cal
- Además, si Amelia solo quiere echarse ¾ de una porción de Nesquik, entonces, ¿Cuántas cucharaditas echará a su taza?
¾ × 2 = 1,5 ← cucharaditas
Se echara 1,5 cucharaditas :D

What is the smallest 3-digit number of the form aaa such that it is divisible by 9? (Here, a represents a digit.)
Answer:
If all three digits need to be the same (I assume that's what aaa means) it's 333
Step-by-step explanation:
For a number XYZ to be divisible by 9, X+Y+Z must be divisible by 9. Here's why:
X*100 + Y * 10 + Z = X + Y + Z + 99*X + 9*Y = X + Y + Z + 9(11X + Y)
So we need to find the smallest a so that a+a+a = 3a is divisible by 9. The smallest would be 0, but 000 is not a real 3-digit number. The next one is 3.

A sinusoidal function whose frequency is 3, maximum value is 15, minimum value is -3 has a y-intercept of 6.
Which function could be the function described?
a. f(x)=9sin(x/3)+6
b. f(x)=9sin(6pix)+3
c. f(x)=9sin(3x)+3
d. f(x)=9sin(6pix)+6
please explain if you can, if not that’s ok!
Answer:
A. f(x) = 9sin(x/3) + 6
Step-by-step explanation:
First, we can eliminate B and C because they have the wrong vertical shift.
Since the y intercept is 6, this means the function has a vertical shift up 6 units, represented by a +6 at the end of the equation.
The amplitude is 9, found by calculating the difference between the minimum and maximum values, and dividing it by 2.
(15 - (-3)) / 2
18 / 2
= 9
Using a calculator, find the period given the frequency.
The period (coefficient of x) is 1/3.
So, putting all of these constants together, the correct equation is:
A. f(x) = 9sin(x/3) + 6
Answer:
A. f(x) = 9sin(x/3) + 6

In a 30-60-90 triangle, the long leg is 60, what is the short leg
Answer:
The shorter leg, which is opposite to the 30- degree angle, is labeled as x. The hypotenuse, which is opposite to the 90-degree angle, is twice the shorter leg length (2x). The longer leg, which is opposite to the 60-degree angle, is equal to the shorter leg's product and the square root of three (x√3).

If the simple interest on $1,000 for 5 years is $300, then what is the interest rate?
Answer:
6%/year
Step-by-step explanation:
Solving our equation
r = 300 / ( 1000 × 5 ) = 0.06
r = 0.06
converting r decimal to a percentage
R = 0.06 * 100 = 6%/year
The interest rate required to
accumulate simple interest of $ 300.00
from a principal of $ 1,000.00
over 5 years is 6% per year.

Answer:
Side length = 5 root 2
perimeter is (5 root 2)*3
Step-by-step explanation:
Use pythagoras
a^2 = b^2 + c^2
a^2 = 5 root 2
(5 root 2)^2 = (c^2)/2 + c^2
75 = (c^2)/2 + c^2
150 = c^2 + 2c^2
150 = 3c^2
50=c^2
root of 50 = 5 root 2
as it is equiliateral triangle all sides are the same
Answer:
Side: 10
Perimeter: 30
Step-by-step explanation:
An equilateral triangle has a height of 5√3. What is the length of each side in the equilateral triangle? What is the perimeter of the equilateral triangle?
In triangles with angles with 30°, 60°, and 90°, the hypotenuse (the angle opposite to the 90° angle) is twice as long as the base, and the height is √3 times as long as the base. To make it easier, this is a list of the sides:
x = base
√3 * x = height
2x = hypotenuse.
Look at the drawing I have attached below
If AD is the base of the triangle ADC, then CD, the height is √3 times AD. If we set AD as x, CD = √3*x = 5√3
√3*x = 5√3
Divide both sides by √3.
x = 5
Then, because altitudes in equilateral triangles bisect the base (CD cuts AB in half), then AB = 10.
The sides in equilateral triangles are equal, so each side is 10.
Then, the perimeter must be 30.
I hope this helps! Feel free to ask any questions!

What is the vertex
And how do I graph it
Answer:
You must know the shape of the graph y = x². Its chart is in the form of an upward parabola. The shape of the graph y = -x² is the same except that it is downward. Finally, to draw the shape of the graph y = -x² + 9, we need to move the previously mentioned graph 9 units upwards.
The formula for the vertex length of a parabolic chart is as follows: x= -b/(2a) b=0 , a= 1 → x= 0, y=-(0)²+9=9
vertex: (0,9)
