Answer:
x ≤ 8
Step-by-step explanation:
Will first used 16 of the 144 ounces for his own water bottle. This leaves 144-16 = 128 ounces.
Dividing that equally amount 16 plastic cups, each cup would have at most
128/16 = 8 ounces.
This means each one would have x ≤ 8 ounces.
The correct inequality is 8 > 6 .
To solve this problem, we need to figure out how many ounces of water Will could pour into each cup. He started with a cooler filled with 144 ounces of water.
Then, he took out 16 ounces for his own water bottle. So, he had 144 - 16 = 128 ounces left.
Since he poured the same amount of water into each of the 16 cups, we can divide the total remaining ounces by the number of cups to find out how many ounces each cup contains:
[tex]\[ \frac{128}{16} = 8 \][/tex]
So, Will could have poured 8 ounces of water into each cup.
Therefore, the correct inequality is:
8 > 6

What is the unemployment rate of this economy?
6.5%
9.3%
13.6%
15.7%
The unemployment rate is calculated as the number of unemployed divided by the labor force, resulting in approximately 9.6%, which is the closest to 9.3% as listed. It is higher than the historical average and the February 2015 rate.
Explanation:The unemployment rate of an economy is calculated by taking the number of unemployed persons and dividing it by the total labor force, and then multiplying the result by 100 to get a percentage.
In this case, using the given figures, the unemployment rate is calculated as follows: 14.8 (unemployed) / 153.9 (labor force) = approximately 9.6%.
This indicates that the correct answer is not explicitly listed, but the closest answer given is 9.3%, which seems to be a typo.
Furthermore, this current unemployment rate is significantly higher than the February 2015 rate of 5.5% and above the historical average unemployment rate, which tends to range between 4% to 6% over time, according to Federal Reserve Economic Data.

The graph of g(x) is obtained by reflecting the graph of f(x)=4|x| over the x-axis.
Which equation describes g(x)?
A) g(x)=|x−4|
B) g(x)=|x+4|
C) g(x)=−4|x|
D) g(x)=|x|−4
That would be choice C.
The graph of 4|x| is shaped like a V whose vertex is at the origin.
Every y value will be positive for y = 4|x| as |x| is always positive and a reflection in the x axis will make every y value negative.
Through moving up c units, the graphs of g can be determined from the graph of f. If we subtract c from f(x), the graph shifts downward. Let [tex]\bold{ h(x) = f(x) - c}[/tex]. Shifting downward c units yields this graph of h from the graph of f.
Given:
[tex]\bold{f(x)=4|x|}[/tex]
Calculation:
It is stated that its graph of [tex]g(x)[/tex] is obtained by reflecting a graph of [tex]f(x)=4|x|[/tex] over the x-axis.When a figure is reflected across the x-axis, the rule for reflection is [tex]\bold{(x,y) \to (x,-y)}[/tex].To use the preceding logic, if the given function is reflected from across the x-axis, then [tex]g(x)=-f (x)[/tex].[tex]\bold{g(x)=-(4|x|)}\\\\\bold{g(x)=-4|x|}\\\\[/tex]
So, the equation [tex]g(x)=-4|x|[/tex] describes [tex]g(x)[/tex].
Therefore, the final choice is "Option C".

write the equation in y-intercept form slope 2 passes through point (5,-2)
The equation is y = 2x - 12
ExplanationEquation in slope intercept form is
[tex]y = mx + b[/tex]
Where,
m = slope
b = y-intercept
Putting the value of slope in this equation:
[tex]y = 2x + b[/tex]
From this we can solve the equation for b
[tex]b = y - 2x[/tex]
[tex]b = -2 - 2(5)[/tex]
[tex]b = -12[/tex]
Now, the equation of y-intercept becomes
[tex]y = 2x - 12[/tex]

(2,7)
(20/7,67/7)
(7,2)
(67/7,20/7)
Answer:
Option 3 (7,2) is right answer.
Step-by-step explanation:
Given two equations
3x-2y=17 ... i
x-3y=1 ... ii
We can solve this by elimination.
coefficients of x are 3 and 1 with LCD = 3
Hence multiply ii equation by 3
3x-9y = 3 ... iv
3x-2y = 17 ... i
Subtract i from iv
-7y = -14
Divide by -7
y =2
Substitute in ii
x-3(2) = 1
x=7
Hence solution is (7,2)
Verify:
We can verify our solution by substituting in i and ii.
3(7)-2(2) = 17 and 7-6 =1

Find all points on the x-axis that are 14 units from the point (3,-7).
Answer:
(3±√147, 0) ≈ (-9.124, 0) and (15.124, 0)
Step-by-step explanation:
The points (x, 0) satisfy the distance formula:
d = 14 = √((x -3)² +(0+7)²)
196 = (x -3)² +49 . . . . . square both sides
147 = (x -3)² . . . . . . . . . subtract 49
3 ±√147 = x . . . . . . . . . take the square root and add 3
The points at distance 14 from (3, -7) on the x-axis are (3±√147, 0).

Both Kelly and Daniel are correct.
Neither Kelly or Daniel is correct.
Kelly is correct, but Daniel is not.
Daniel is correct, but Kelly is not.
Answer:
The answer is Daniel is correct, but Kelly is not.
Step-by-step explanation:
Answer:
(D) Daniel is correct, but Kelly is not.
Step-by-step explanation:
It is given that Line segment NT intersects line segment MR forming four angles. Angles 1 and 3 are vertical angles. Angles 2 and 4 are vertical angles.
Kelly's Proof:∠2 = ∠4 (Vertical angles are congruent)
∠1 = ∠3 (Vertical angles are congruent)
Using Vertical Angle Theorem the vertical angles are equal.
since, we cannot use the direct information given in the question in order to prove the same.
Thus, the justification given by Kelly is incorrect.
Now, Daniel's proof:
∠1 + ∠2 = 180°(Definition of Supplementary Angles)
and ∠1 + ∠4 = 180° (Definition of Supplementary Angles)
⇒∠1 + ∠2 = ∠1 + ∠4(Transitive Property of Equality)
Hence, ∠2 = ∠4(Subtraction Property of Equality)
Thus, the justification of Daniel is correct.
Hence, option (D) is correct.

A dolphin is swimming with her friend. The dolphin jumps to a height of 4.54.54, point, 5 meters above the surface of the water as her friend swims 9.89.89, point, 8 meters directly below her. What is the position of the dolphin's friend relative to the surface of the water?
The dolphin's friend is 8.63 meters below the surface of the water relative to the dolphin's jumping point.
Explanation:To solve this problem, we can use the kinematic equation that relates initial velocity, final velocity, acceleration, and displacement:
vf² = vi² + 2ad
Knowns:Plug in the knowns: (-13.0 m/s)² = (0 m/s)² + 2(-9.8 m/s²)(d)Simplify and solve for d: d = (169 m²/s²) / (-19.6 m/s²)Calculating: d = -8.63 mThe positive value of d indicates that the dolphin's friend is 8.63 meters below the surface of the water relative to the dolphin's jumping point.
The dolphin's friend is 5.3 meters below the surface of the water.
Let's reassess the problem with the given constraints more carefully.
We need to find the position of the dolphin's friend relative to the surface of the water.
1. Dolphin's height above the water:
[tex]\[ 4.5 \text{ meters above the surface} \][/tex]
2. Distance between the dolphin and her friend:
[tex]\[ 9.8 \text{ meters below the dolphin} \][/tex]
Since the friend is swimming below the dolphin, we need to subtract this distance from the height of the dolphin above the surface to find the position of the friend relative to the water surface.
3. Calculate the position of the dolphin's friend:
[tex]\[ \text{Position of friend} = 4.5 \text{ meters} - 9.8 \text{ meters} \][/tex]
[tex]\[ \text{Position of friend} = -5.3 \text{ meters} \][/tex]
This means the dolphin's friend is 5.3 meters below the surface of the water.

The graph of function g is a vertical stretch of the graph of function f by a factor of 3. Which equation describes function g?
A. g(x)=3f(x)
B. g(x)=f(3x)
C. g(x)=f(x3)
D. g(x)=13f(x)
What transformation takes the graph of f(x)=3x+8 to the graph of g(x)=3x+6 ?
A. translation 2 units up
B. translation 2 units left
C. translation 2 units down
D. translation 2 units right
Answer:
Step-by-step explanation:
A vertical stretch by a factor of k means that the point (x, y) on the graph of f (x) is transformed to the point (x, ky) on the graph of g(x), where k <1.
If k =1, then same graph we obtain and if k>1 we get a vertically shrink graph.
In our question, there is a vertical stretch of 3. This means new graph would have points as (x,y/3)
i.e. instead of f(x) = y, we have now f(x) = y/3
So transformation is g(x) = 3f(x)
Option A is correct.
2) Here f(x) = 3x+8 is transformed to g(x) =3x+6
i.e. y intercept is reduced by 2 units. Hence there is a translation of 2 units down.
I did not have the answer to the second question but here is the first.
A rectangular prism has dimensions of x + 1, x - 1, and x. Write an expression for the total volume of the prism.
We have been given the dimensions of the rectangular prism.
Lets say that the length, width, and height of the rectangular prism are:
Length [tex]= x+1[/tex]
Width [tex]=x-1[/tex]
Height[tex]=x[/tex]
Volume of a rectangular prism is given by:
[tex]length \times width\times height[/tex]
Plugging the values of length, width, and height, we get:
Total volume of the prism [tex]= (x+1)\times(x-1)\times x[/tex]
[tex]=(x^2-1)x=x^3-x[/tex] (we have used [tex](a+b)\times (a-b)=a^2-b^2[/tex])
So, the expression for the total volume of the prism is:
[tex](x^3-x)[/tex]

If sin(x) = 1/3 and sec(y) = 17/15 , where x and y lie between 0 and π/2, evaluate the expression using trigonometric identities. (enter an exact answer.) "sin(2y)"
Answer: sin2y =240/289 where 0<y <π/2
Step-by-step explanation:
Given sin(x) = 1/3 and sec(y) = 17/15 , where x and y lie between 0 and π/2.
We now that
[tex]cosy = \frac{1}{secy} =\frac{15}{17} \\and\\\text{using identity } sin^2y+cos^2y=1\\\text{we have}\\siny=\sqrt{1-cos^2y}=\sqrt{1-(\frac{15}{17} )^2}=\sqrt{1-\frac{225}{289} }=\sqrt{\frac{64}{289} }=\frac{8}{17} \\\Rightarrow\ siny=\frac{8}{17} \\\text{Now we are using identity sin2A=2sinAcosA we have}\\sin2y=2\cdot\ siny\cdot\ cosy=2\cdot\ \frac{8}{17} \cdot\ \frac{15}{17} =\frac{240}{289}[/tex]
To solve the question, we firstly find cos(y) from 'sec(y) = 17/15' because secant is the reciprocal of cosine. Then, we use the Pythagorean identity to find sin(y). Finally, we substitute these values into the double angle identity 'sin(2y) = 2sin(y)cos(y)' to find the final answer.
Explanation:In this high school level mathematics problem, 'sin(x) = 1/3' and 'sec(y) = 17/15' are given. From 'sec(y) = 17/15', we can calculate cos(y) because secant is the reciprocal of cosine. Hence, 'cos(y) = 15/17'. The question asks for the evaluation of the expression 'sin(2y)'. Here, we can use a trigonometric identity for double angles, which states 'sin(2y) = 2sin(y)cos(y)'.
However, we are only given secant of y, not sine. To find sin(y), we can use the Pythagorean identity. According to this identity, 'sin^2(y) = 1 - cos^2(y)'. So, 'sin(y) = sqrt[1 - (15/17)^2]'.
So, the final answer becomes 'sin(2y) = 2 * √[1 - (15/17)²] * 15/17'. It's useful to note that you should always check that your angle lies within the given range when using a square root in trigonometry, to ensure your answer is correct.

Radhika borrowed Rs.12000 from her friends. Out of which Rs.4000 were borrowed at 18% and the remaining at 15% rate of interest per annum. What is the total interest after 3 years?
Answer-
The total interest after 3 years is Rs.5760 .
Solution-
Total money borrowed = Rs.12000
Out of those Rs.4000 is of 18% interest rate and remaining 12000-4000=8000 is of 15% interest rate.
[tex]\text{Total interest}=\frac{P_1\times r_1\times t}{100}+\frac{P_2\times r_2\times t}{100}[/tex]
Where,
P₁ = principal amount = Rs.4000
P₂ = principal amount = Rs.8000
r₁ = rate of interest of P₁ = 18%
r₂ = rate of interest of P₂ = 15%
t = time period = 3 years
[tex]\text{Total interest}=\frac{4000\times 18\times 3}{100}+\frac{8000\times 15\times 3}{100}=2160+3600=5760[/tex]
