Answer:
A an = -3 * (1/8) ^ (n-1)
Step-by-step explanation:
We know the first term a1 = -3
And the common ratio r = 1/8 from the an = an-1 * 1/8
The explicit formula is
an = a1 r^ (n-1)
an = -3 * (1/8) ^ (n-1)
Answer:
A
Step-by-step explanation:
a₁ = -3 ------> first term
r ----> common ratio
[tex]a_{n}=a_{n-1}*\frac{1}{8}\\\\r=\frac{1}{8}\\\\a_{n}=a_{1}*r^{n-1}\\\\a_{n}=-3*(\frac{1}{8})^{n-1}[/tex]
Density is a physical property of a molecule that’s measured as mass per unit volume. (a) Given that density is usually expressed in the units of g/cm3, calculate the density of a cube of plastic that has a mass of 2.331 g and an edge length of 1.500 cm (volume of a cube is V = l3). (b) Draw two liquids in a graduated cylinder on a separate sheet of paper. You won’t submit the drawing as part of your answer. Liquid A has a density of 1.004 g/cm3 and Liquid B has a density of 0.6223 g/cm3. Assume they don’t mix. Label which liquid is on top and which liquid is on bottom, and then draw the cube where you would expect it to be if it’s dropped into the graduated cylinder with these two liquids. Explain the location for liquid A, liquid B, and the cube in the graduated cylinder.
Answer:
The answer is given below
Step-by-step explanation:
a) Density is the ratio of mass to volume. Given that the mass of a cube = 2.331 g and the edge length (l) = 1.500 cm
The volume = l³ = 1.5³ = 3.375 cm³
Therefore, [tex]Density=\frac{mass}{volume}=\frac{2.331\ g}{3.375\ cm^3}=0.691\ g/cm^3[/tex]
b) The density of liquid A is 1.004 g/cm3 and Liquid B has a density of 0.6223 g/cm3. Since Liquid A is more denser than liquid B, liquid B would float when mixed with liquid B. Liquid B is on top and liquid A is at the bottom.
C) If the cube is also dropped in the cylinder, since its density is more than the density of liquid B, liquid B would be on top, then the cube and lastly Liquid A would be at the bottom.

Please help answer this question Minni has to buy stickers, erasers, and a pencil. She can only spend $4. A sticker costs $0.35, an eraser costs $0.99, and a pencil costs $0.59. Can Minni buy 2 stickers and 2 erasers? [Use the inequality 0.35x + 0.99y + 0.59 ≤ 4] (1 point) Select one: a. Yes, because the total will be $3.27 b. Yes, because the total will be $1.93 c. No, because the total will be $4.27 d. No, because the total will be $5.93
Answer: A
Since you already have an equation just put in how many stickers and erasers she wants to get: 0.35(2)+0.99(2)+0.59≤4.
Then you multiply: .35(2)=.70. .99(2)=1.98.
Then add: .70+1.98+.59=3.27, so yes she can since 3.27 is less than 4 so the answer is A
Answer:
A. yes, because the total will be $3.27
Step-by-step explanation:
0.35x + 0.99y + 0.59 ≤ 4
0.35(2) + 0.99(2) + 0.59 ≤ 4
0.70 + 1.98 + 0.59 ≤ 4
3.27 ≤ 4

Which situation shows a constant rate of change? A. The number of points scored in a basketball game compared with the number of minutes played. B. The height of a monkey swinging from branch to branch over time. C. the height of a bouncing ball over time. D. The amount a person pays for gas compared with the number of gallons purchased.
Answer: D
Step-by-step explanation:
A constant rate of change means that for every x, y increases the same amount.
In the situation "The amount a person pays for gas compared with the number of gallons purchased ," the independent quantity, or x-value, is the number of gallons, and the dependent quantity, or y-value, is the amount paid. Since gas has a set price per gallon, for every gallon purchased, the total amount paid goes up the same amount. This means it has a constant rate of change.

A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries negative 16, negative 17, negative 18, negative 19. A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries 16, 17, 19, 20. A 2-column table with 4 rows. Column 1 is labeled x with entries 17, 18, 19, 20. Column 2 is labeled y with entries negative 20, negative 19, negative 18, negative 17.
Answer:
Third option
Step-by-step explanation:
In linear functions, if we take two any points (x1, y1) and (x2, y2), the next relationship must be satisfied: (y2- y1)/(x2 - x1) = constant
The third option is:
x | y
17 | 16
18 | 17
19 | 19
20 | 20
Taking the points of the previous table, we get:
(17-16)/(18-17) = 1
(19-17)/(19-18) = 2
(20-19)/(20-19) = 1
which is not constant for all points. Then, the relationship is not linear.
Answer:
third one
Step-by-step explanation:
its constant and increasing the other ones are not constant but increase

Hey there! :)
Answer:
56.7 kg.
Step-by-step explanation:
Use the density formula to solve for the mass:
D = m/V.
Rearrange in terms of mass, or 'm':
DV = m.
Solve for the volume:
0.06 × 0.9 × 1.5 = 0.081 m³.
Plug this into the equation along with the density:
700 × 0.081 = 56.7 kg.

1/2(4x-12)=5 what is the value of x
Answer:
x = 11/2 = 5^1/2 =5.5
Step-by-step explanation:
1/2(4x-12)=5
Multiply both sides by 2, the reciprocal of 2/1 =0.5
4x−12=5×2
Multiply 5 and 2 to get 10.
4x−12=10
Add 12 to both sides.
4x=10+12
Add 10 and 12 to get 22.
4x=22
Divide both sides by 4.
x = 22/4
Reduce the fraction 4/22 =5.5 to lowest terms by extracting and canceling out 2.
x = 11/2
Answer:
5.5
Step-by-step explanation:

What are the resulting coordinates of triangle L 'M' N' after reflecting triangle LMN across the y= x?
Answer:
L' = (-1,1)
N' = (-1,4)
M' = (-4,2)
Step-by-step explanation:
Reflecting across y = x basically means switching the positions of x and y. In this case switching the coordinates.
L = (1,-1) and L' = (-1,1)
N = (4,-1) and N' = (-1,4)
M= (2,-4) and M' = (-4,2)
given f(x) and g(x) = k.f(x), use the graph to determine the value of k
Answer: The answer is -3
Step-by-step explanation:
g(x)=kf(x)
g(-3)=kf(-3)
To solve this for k we will need to find the values for both g(-3) and f(-3).
g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.
g(-3)=-3
f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.
f(-3)=1
So our equation becomes:
g(-3)=kf(-3)
-3=k(1)
-3=k
So k=-3.

A parallel line would have slope m =
The solution is
Answer:
The answer is - 4Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
12x + 3y = 15
Express it in the form y = mx + c
3y = -12x + 15
Divide all terms by 3
y = - 4x + 5
From the equation m = - 4
Since the lines are parallel their slope are also the same
So the slope of the parallel line is also - 4

Need help with trig problem in pic
Answer:
a) [tex]cos(\alpha)=-\frac{3}{5}\\[/tex]
b) [tex]\sin(\beta)= \frac{\sqrt{3} }{2}[/tex]
c) [tex]\frac{4+3\sqrt{3} }{10}\\[/tex]
d) [tex]\alpha\approx 53.1^o[/tex]
Step-by-step explanation:
a) The problem tells us that angle [tex]\alpha[/tex] is in the second quadrant. We know that in that quadrant the cosine is negative.
We can use the Pythagorean identity:
[tex]tan^2(\alpha)+1=sec^2(\alpha)\\(-\frac{4}{3})^2 +1=sec^2(\alpha)\\sec^2(\alpha)=\frac{16}{9} +1\\sec^2(\alpha)=\frac{25}{9} \\sec(\alpha) =+/- \frac{5}{3}\\cos(\alpha)=+/- \frac{3}{5}[/tex]
Where we have used that the secant of an angle is the reciprocal of the cos of the angle.
Since we know that the cosine must be negative because the angle is in the second quadrant, then we take the negative answer:
[tex]cos(\alpha)=-\frac{3}{5}[/tex]
b) This angle is in the first quadrant (where the sine function is positive. They give us the value of the cosine of the angle, so we can use the Pythagorean identity to find the value of the sine of that angle:
[tex]cos (\beta)=\frac{1}{2} \\\\sin^2(\beta)=1-cos^2(\beta)\\sin^2(\beta)=1-\frac{1}{4} \\\\sin^2(\beta)=\frac{3}{4} \\sin(\beta)=+/- \frac{\sqrt{3} }{2} \\sin(\beta)= \frac{\sqrt{3} }{2}[/tex]
where we took the positive value, since we know that the angle is in the first quadrant.
c) We can now find [tex]sin(\alpha -\beta)[/tex] by using the identity:
[tex]sin(\alpha -\beta)=sin(\alpha)\,cos(\beta)-cos(\alpha)\,sin(\beta)\\[/tex]
Notice that we need to find [tex]sin(\alpha)[/tex], which we do via the Pythagorean identity and knowing the value of the cosine found in part a) above:
[tex]sin(\alpha)=\sqrt{1-cos^2(\alpha)} \\sin(\alpha)=\sqrt{1-\frac{9}{25} )} \\sin(\alpha)=\sqrt{\frac{16}{25} )} \\sin(\alpha)=\frac{4}{5}[/tex]
Then:
[tex]sin(\alpha -\beta)=\frac{4}{5}\,\frac{1}{2} -(-\frac{3}{5}) \,\frac{\sqrt{3} }{2} \\sin(\alpha -\beta)=\frac{2}{5}+\frac{3\sqrt{3} }{10}=\frac{4+3\sqrt{3} }{10}[/tex]
d)
Since [tex]sin(\alpha)=\frac{4}{5}[/tex]
then [tex]\alpha=arcsin(\frac{4}{5} )\approx 53.1^o[/tex]
