The y value in the table gets multiplied by 4 every time the x value goes up by 1. You can check your work using the values in the table given to you. 0.25 times four is 1. 1 times four is 4, and so on as the table goes.
The ratio would be written as 1:4

Law of Cosines: c2 = a2 + b2 - 2ab cos C
Answers
Answer:
4.2 ft
Step-by-step explanation:
Given the equation for the Law of Cosines, we can rewrite the equation to solve for "c" directly:
[tex]c^2=a^2+b^2-2ab(cosC)\\c=\sqrt{a^2+b^2-2ab(cosC)}\\c=\sqrt{7^2+8^2-2(7)(8)(cos32)}\\c=\sqrt{49+64-2(56)(cos32)}\\c=\sqrt{113-112(cos32)}\\c=\sqrt{113-94.98138677}\\c=\sqrt{18.01861323}\\c=4.244833711\\c=4.2[/tex]
So the length of c is approximately 4.2 ft
X and Y together can do a piece of work in 10 days and X alone can do it in 15 days would Y alone can finish the work ?
Answers
Answer:
Y alone can do the piece of work in 30 days.
Step-by-step explanation:
Proportions
Let's make:
N = days for Y to finish the work alone
Since X alone can do it in 15 days, each day he can do a proportion of 1/15 of the piece of work.
Since Y alone can (possibly) do it in N days, each day he can do 1/N parts of the work.
Together, they do
[tex]\displaystyle \frac{1}{15}+\frac{1}{N}[/tex]
parts of the work per day. We know they can finish it in 10 days, thus:
[tex]\displaystyle \frac{1}{15}+\frac{1}{N}=\frac{1}{10}[/tex]
Rearranging:
[tex]\displaystyle \frac{1}{N}=\frac{1}{10}-\frac{1}{15}[/tex]
The LCM of 10 and 15 is 30, thus operating:
[tex]\displaystyle \frac{1}{N}=\frac{3-2}{30}=\frac{1}{30}[/tex]
Solving for N:
N = 30
Y alone can do the piece of work in 30 days.
b) The adjoining cylindrical vessel is 70 CM high and the radius
of its base is 35cm. If it contains some water up to the height
of 20 cm, how much water is required to fill the vessel
completely
Answers
[tex]\large\boxed{\pink{\sf \leadsto The \ Volume \ of \ water \ needed \ to \ be \ filled \ is \ 192,500 cm^3}}[/tex]
Step-by-step explanation:Given that , cylindrical vessel is 70 cm high and the radius of its base is 35cm . it contains some water up to the height of 20 cm .
And we need to find the water required to fill it completely .
Figure :-
[tex]\setlength{\unitlength}{1 cm}\begin{picture}(12,12)\linethickness{0.4mm}\put(0,0){\line(0,1){5}} \put(3,0){\line(0,1){5}}\qbezier(0,5)(1.5,4)(3,5)\qbezier(0.001,0)(1.5,1)(3,0)\qbezier(0,5)(1.5,6)(3,5)\qbezier(0.001,0)( 1.5, - 1)(3,0)\put(3.5,2){\vector(0,-1){2}}\put(3.5,3){\vector(0,1){2}}\put(3.5,2.5){$\sf 70 cm $}\put(1.4,0){\line(1,0){1.6}} \put(1.4,0.2){$\sf 35cm$}\qbezier(0,2.5)(1.5,3.5)(3,2.5)\qbezier(0,2.5)(1.5, 1.8)(3,2.5)\put(-1,1){\vector(0,-1){1}}\put(-1,1.5){\vector(0,1){1}}\put(-1.3,1.2){$\sf 20cm $}\end{picture}[/tex]
Let us take the Volume of Cylinder be V and the volume of cylinder filled be v . Let the volume required to be filled be X .
From the figure it's clear that , Volume of water required to fill the cylindrical vessel completely will be :-
[tex]\tt:\implies v + x = V \:\: \bigg\lgroup \red{\bf As \ per \ our \ assumption }\bigg\rgroup \\\\\tt:\implies x = V - v \\\\\tt:\implies x = \pi r^2 H - \pi r^2 h \\\\\tt:\implies x = \pi r^2 ( H - h ) \\\\\tt:\implies x = \pi r^2 ( 70 cm - 20 cm ) \\\\\tt:\implies x = \dfrac{22}{7} \times (35 cm)^2 \times 50 cm \\\\\tt:\implies x = \dfrac{22\times 35 cm \times 35 cm }{7} \times 50 cm \\\\\underline{\boxed{\red{\tt \longmapsto Volume_{fill } = 192,500 cm^3}}}[/tex]
Hence the required volume of water to be filled is 192,500 cm³.Then solve the equation.

for which of the following does f(-3)=0 select all that apply

B. f(x) = -x^2 – 3x
C. f(x) = -(x + 3)^2
D. f(x) = x^2 + 5x + 4
E. f(x) = 2x - 3(x + 1)
F. f(x) = -2(x - 2) + 3x
Answers
The function which has the value of 0 at x = -3 are C. f(x) = (x + 3)² and E. f(x) = 2x - 3(x + 1).
What is Function?
A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
A. f(x) = (x - 3)²
Substituting x = 3,
f(-3) = (-3 - 3)² = 36
B. f(x) = x² - 3x
f(-3) = (-3)² - (3 × -3) = 9 + 9 = 18
C. f(x) = (x + 3)²
f(-3) = (-3 + 3)² = 0
Here the function value is 0.
D. f(x) = x² + 5x + 4
f(-3) = 9 - 15 + 4 = -2
E. f(x) = 2x - 3(x + 1)
f(-3) = -6 - 3(-3 + 1) = 0
Here the function value is 0.
F. f(x) = -2(x - 2) + 3x
f(-3) = 1
Hence the required functions are C. f(x) = (x + 3)² and E. f(x) = 2x - 3(x + 1).

Addison made fancy orange costume decorations for each of the 9 dancers in her year-end dance performance. She cut 7 1/5 yards of ribbon into equal pieces to make the decorations. How long was each piece of ribbon?
Answers
Answer:
0.8 yards or 28.8 inches
Step-by-step explanation:
I always turn fractions into decimals because it is easier to figure it out and simpler.
So 1/5 would be 2/10 because you multiply the whole thing by 2 to make the denominator 10 so you can turn it into a decimal.
So the decimal is 0.2
You would divide 7.2 by 9 to get 0.8 yards which is 28.8 inches.

A trade school would like to measure the long-term success of its graduates after they leave the school, and emails a survey requesting information from graduates about their work experience. One question asks graduates if they are currently employed in the field they studied in school, while another asks them to share their annual salary. What type of bias is most likely to be present in the survey results?
This is response bias because some graduates may not provide accurate information.
This is question wording bias because many graduates may misunderstand the questions asked.
This is voluntary response bias because graduates may choose to be part of the sample.
This is nonresponse bias because many graduates may choose not to respond to the email survey.
Answers
Answer:c will be the answer YW!
Step-by-step explanation:
This is voluntary response bias because graduates may choose to be part of the sample that is most likely to be present in the survey results. Thus option C is correct.
What is a survey?A survey is a set of inquiries designed to elicit specified data from a certain population. Surveys can be carried out via the radio, by postal, online, at town squares, and even in shopping centers.
When elements are personality volunteers who are degree holders, volunteered response bias emerges. Voters determine whether or not they will participate in the sample once the research involved a group of people to do so.
Graduating students may select to be a part of the population that is the most likely to appear in the survey results, resulting in voluntary response bias. Therefore, option C is the correct option.

Find the value of each variable
Answers
Answer:
x = 17[tex]\sqrt{3}[/tex]
y = 17
Step-by-step explanation:
You would need to use the following trigonometric functions cosine and sin. Sin is used for the y-variable to get the answer and cosine is used for the x-variable to get the answer. For this case, you would need to do 34 sin 30 for y and 34 cos 30 for x. You should get 17 for y and 17 root 3 for x when you put it in the calculator.
The value of each variable are,
x = 17√3
y = 17
We have to give that,
A triangle is shown in the image.
Now, from the triangle we get;
cos 30° = x/34
Solve for x,
√3/2 = x/34
Cross multiply,
34√3 = 2 × x
2x = 34√3
x = 17√3
And, We get;
⇒ sin 30° = y/34
⇒ 1/2 = y/34
Cross multiply,
⇒ 34 = 2y
⇒ y = 17
Hence, the value of each variable is,
x = 17√3
y = 17
