Answer:
Milk Glass A can hold more milk.
Step-by-step explanation:
This problem mostly relies on the diameter of the milk glass.
To solve the problem, we'll find the volume of each glass as though it were a cylinder.
First, we start with the area of the base of each cylinder.
Using the formula [tex]\pi r^{2}[/tex], we can find the area of each base.
Note that r represents radius, which is half of the diameter, d.
The area of the base on Milk Glass A can be found with: [tex]\pi 1.75^2[/tex] which equals 9.62 inches squared.
The area of the base on Milk Glass B can be found with: [tex]\pi 0.75^2[/tex] which equals 1.77 inches squared.
Now that we have the area of each base, we just multiple the area by the height to get the full volume.
The volume of Milk Glass A can be found by multiplying [tex]9.62*4[/tex] which equals 38.48 cubic inches.
The volume of Milk Glass B can be found by multiplying [tex]1.77 *5[/tex] which equals 8.85 cubic inches.
Therefore, the larger answer of 38.48 cubic inches means Milk Glass A can hold more milk.

Which of the following equations is the translation 2 units up of the graph of y= 1x1
1.y=1x-21
2.y=1x+21
3.y=1x1-2
4.y=1x1+2
Answer:
4. y = |x| + 2
Step-by-step explanation:
"g(x) = |x| + k" means that f(x) will be translated however many units up or down depending on k. If k is positive, the graph will translate up. If k is negative, the graph will translate down. Because we need to translate up, the value of k needs to be positive. The best answer choice is choice 4, y = |x| + 2.
We can eliminate choices 1 and 2 because the way the equations are set up are for the horizontal translations.
g(x) = |x - h| are for horizontal translations.
g(x) = |x| + k are for vertical translations.
The third choice is wrong as well because k is negative, not positive.

Simplifying the equations
Penny
2x - y = -1y = 2x + 1Ravi
2x + 3y = 33y = -2x + 3y = -2/3x + 3Courtney
-4x - 6y = -66y = -4x + 6y = -2/3x + 3Edwin
6x + 6y = 96y = -6x + 9y = -x + 9Ravi and Courtney would have infinitely many solutions because they are the same equation.
Answer:
Ravi and Courtney have the same equation so they will have infinetely many solutions.
Step-by-step explanation:
Step 1: Solve each equation for y
Penny → [tex]2x - y = 1[/tex]
→ [tex]-y + 2x - 2x = 1 - 2x[/tex]
→ [tex](-y) * -1 = (1 - 2x) * -1[/tex]
→ [tex]y = 2x - 1[/tex]
Ravi → [tex]2x + 3y = 3[/tex]
→ [tex]3y + 2x - 2x = 3 - 2x[/tex]
→ [tex](3y)/3 = (3 - 2x)/3[/tex]
→ [tex]y = -2/3x + 1[/tex]
Courtney → [tex]-4x - 6y = -6[/tex]
→ [tex]-6y - 4x + 4x = -6 + 4x[/tex]
→ [tex](-6y)/-6 = (-6 + 4x)/-6[/tex]
→ [tex]y = -2/3x + 1[/tex]
Edwin → [tex]6x + 6y = 9[/tex]
→ [tex]6y + 6x - 6x = 9 - 6x[/tex]

Based on an LG smartphone survey, assume that 51% of adults with smartphones use
them in theaters. In a separate survey of 250 adults with smartphones, it is found that
109 use them in theaters.
Using the z-distribution, it is found that the sample is enough evidence that the proportion is below 51%.
What are the hypotheses tested?At the null hypotheses, it is tested if the proportion is of 51%, that is:
[tex]H_0: p = 0.51[/tex]
At the alternative hypotheses, it is tested if the proportion is less than 51%, hence:
[tex]H_1: p < 0.51[/tex].
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.In this problem, the parameters are given as follows:
[tex]p = 0.51, n = 250, \overline{p} = \frac{109}{250} = 0.436[/tex]
Hence, the test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.436 - 0.51}{\sqrt{\frac{0.51(0.49)}{250}}}[/tex]
z = -2.34.
What is the decision?Considering a left-tailed test, as we are testing if the proportion is less than a value, with a standard significance level of 0.05, the critical value is of [tex]z^{\ast} = -1.645[/tex].
Since the test statistic is less than the critical value for the left tailed test, we reject the null hypothesis, and find that the sample is enough evidence that the proportion is below 51%.

What is the vertex of g(x) = –3x2 18x 2? (3, –25) (–3, –25) (3, 29) (–3, 29)
Answer:
f(x) = -(x + 8)(x -14)
= -(x2 - 112 - 6x)
= -x2 + 6x + 112 --- (1)
We know the graph of an equation y = ax2 + bx + c where a ≠ 0 is a parabola. The parabola opens upwards if a > 0 and opens downwards if a < 0. The vertex of the parabola is the point where the axis and parabola intersect. Its x coordinate x = -b/2a and its y coordinate is found out by substituting x = -b/2a in the parabola equation.
The parabola given in the problem statement has a negative coefficient of x2 and hence it is a parabola which opens downwards. Also for the equation
a = -1, b = 6 and c = 112. Therefor the x-coordinate of the vertex is
x = -b/2a
= -(6)/[2(-1)]
= 3
Substituting the value of x = 3 in equation (1) we get,
Now y = -(3)2 + 6(3) + 112
= -9 + 18 + 112 = 121
So the vertex point coordinates are (3, 121) and the y value is 121.
The graph below verifies the vertex point.

For a typical human height of 2 meter what is the horizon distance on earth (r=6378) (b mars R=3,340
The horizon's distance for a typical human being (2 m height) for earth is 5 km, for mars it is 3.7 km, for moon its 2.6 km, and for Diemos it is 0.15 km (all calculations approx).
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
The complete question is:
" For a typical human height of 2 meters, what is the horizon distance on A) Earth (R=6378 km); B) Mars ( 3,374 km); C) The Moon ( 1,738 km); Mars' moon Diemos ( 6 km) "
Radius touching the line which passes touching the circle (tangent) is perpendicular(to 90°) to it.
Consider the diagram attached below:
The distance D is the distance of horizon from the eyesight of viewer.
The value of h is the height of the observer.
For the triangle ABC, the length of the hypotenuse is: h + R
Other two sides which are mutually perpendicular are of length R and D.
Thus, by using Pythagoras theorem, we get:
[tex]R^2 + D^2 = (h+R)^2\\D = \sqrt{h^2 + R^2 + 2hR -R^2}\\\\D = \sqrt{h^2 + 2hR}\\[/tex]
(positive root as D is representing length, a non-negative quantity).
We're given h = 2, so we get:
[tex]D = \sqrt{4+4R} = 2\sqrt{1+R} \: \rm m[/tex]
A) Earth (R=6378 km);6378 km = 6378000 m
[tex]D = 2\sqrt{6379001} \approx 5051 \: \rm m \approx 5 \: km[/tex]
B) Mars ( 3,374 km);3374 km = 3374000 m
[tex]D = 2\sqrt{3374001} \approx 3674 \: \rm m \approx 3.7 \: km[/tex]
C) The Moon ( 1,738 km);
1738 km = 1738000 m
[tex]D = 2\sqrt{1738001} \approx 2637 \: \rm m \approx 2.6 \: km[/tex]
D)Mars' moon Diemos ( 6 km)
6 km = 6000 m
[tex]D = 2\sqrt{6001} = 154.93 \: \rm m \approx 0.15 \: km[/tex]
Thus, the horizon's distance for a typical human being (2 m height) for earth is 5 km, for mars it is 3.7 km, for moon its 2.6 km, and for Diemos it is 0.15 km (all calculations approx).
