Answers asap now!!!!!!!!
Step-by-step explanation:
1.
The given equation is :
6x+2y=14
We need to write it in the function form.
Taking 2 common from both sides,
2(3x+y)=2(7)
So,
(3x+y)=7
Subtract 3x from both sides,
y+3x-3x=7-3x
y = 7-3x
So, the correct option is (c).
2. f(x) = 3x-4
We need to find f(2). Put x = 2 in the above function.
f(2) = 3(2)-4
= 6-4
= 2
The correct option is (D).

The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 60 mm
Answer:
The volume of the sphere is increasing at a rate of 56,549 cubic millimeters per second.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In which r is the radius.
Solving this question:
The first step do solve this question is derivating V implictly in function of t. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
The radius of a sphere is increasing at a rate of 5 mm/s.
This means that [tex]\frac{dr}{dt} = 5[/tex]
Diameter is 60 mm
This means that [tex]r = \frac{60}{2} = 30[/tex]
How fast is the volume increasing (in mm3/s) when the diameter is 60 mm?
This is [tex]\frac{dV}{dt}[/tex]. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
[tex]\frac{dV}{dt} = 4\pi*30^2*5 = 900*20\pi = 56549[/tex]
The volume of the sphere is increasing at a rate of 56,549 cubic millimeters per second.

Answer:
20 cubic meters
Step-by-step explanation:
Volume of a rectangular prism = length * width * height
Dividing the figure into 2 rectangular prisms
Volume of First rectangular prisms = 4m * 2m * 1m
Volume of First rectangular prism = 8m^3
Volume of second rectangular prism = 4m * 3m * 1m
Volume of second rectangular prism = 12m^3
Taking the sum
Volume of the figure = 8m^3 + 12m^3
Volume of the figure = 20 cubic meters

Solve 2Q + 5s=r for s and show ALL your steps.
Answer:
2q-r= 5s
divide both sides by 5
2q-r/s =5s/5
therefore S= 2q-r/s
Answer:
Step-by-step explanation:
Subtract 2Q from both sides
2Q + 5s − 2Q = r − 2Q
Simplify
5s = r − 2Q
Divide both sides by 5
[tex]\frac{5s}{5} =\frac{r}{5} -\frac{20}{5}[/tex]

In a class of students, the following data table summarizes how many students play
an instrument or a sport. What is the probability that a student chosen randomly
from the class plays a sport or an instrument?
Answer:
19/28
Step-by-step explanation:
People who count: 4 + 2 + 13 = 19
Total amount of pplz: 19 + 9 = 28
Answer:
15/28
Step-by-step explanation:
The total amount of students in the class is 28. This will be useful for later.
From this table, we can see that 2 people play sports alone and 13 play an instrument alone. Since it says the number of students that play a sport or an instrument, this means that the top left box is not counted. This leaves you with an answer of 15/28.
A basketball player has a 0.654 probability of making a free throw. If the player shoots 13 free throws, what is the probability that she makes less than 6 of them?
Insert the correct symbol to represent this probability.
Provide your answer below:
P(X
5)
Using the binomial distribution, it is found that there is a 0.0432 = 4.32% probability that she makes less than 6 of them.
-----------------------
For each throw, there are only two possible outcomes. Either she makes it, or she misses it. The probability of making a throw is independent of any other throw, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
x is the number of successes. n is the number of trials.p is the probability of a success on a single trial.The probability of making less than 6 is:
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{13,0}.(0.654)^{0}.(0.346)^{13} \approx 0[/tex]
[tex]P(X = 1) = C_{13,1}.(0.654)^{1}.(0.346)^{12} \approx 0[/tex]
[tex]P(X = 2) = C_{13,2}.(0.654)^{2}.(0.346)^{11} = 0.0003[/tex]
[tex]P(X = 3) = C_{13,3}.(0.654)^{3}.(0.346)^{10} = 0.0020[/tex]
[tex]P(X = 4) = C_{13,4}.(0.654)^{4}.(0.346)^{9} = 0.0093[/tex]
[tex]P(X = 5) = C_{13,5}.(0.654)^{5}.(0.346)^{8} = 0.0316[/tex]
Then
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0 + 0 + 0.0003 + 0.0020 + 0.0093 + 0.0316 = 0.0432[/tex]
0.0432 = 4.32% probability that she makes less than 6 of them.

it takes electricians 36 days to wire a new housing subdivision. how many days would 32 electricians take to do the same job?
Answer:
The 32 electricians will take 1 day and 3 hours to complete the wiring.
Step-by-step explanation:
Since it takes electricians 36 days to wire a new housing subdivision, to determine how many days would 32 electricians take to do the same job the following calculation must be performed:
36/32 = X
1.125 = X
1 = 24
0.125 = X
0.125 x 24 = X
3 = X
Therefore, the 32 electricians will take 1 day and 3 hours to complete the wiring.
2. Two puppies together weigh 22 kilograms 300 grams. If one
puppy weighs 9 kilograms 500 grams, how heavy is the other
puppy?
Tip: 1 kg = 1000 g
answer asap
Answer:
B = 12800 grams or 12kg 800 grams.
Step-by-step explanation:
Let the two puppies be A and B respectively.
Translating the word problem into an algebraic expression, we have;
A + B = 22kg 300g
A = 9kg 500g
Conversion;
1 Kilograms = 1000 grams.
9kg 500g = 9*1000 + 500 = 9500 grams
22kg 300g = 22*1000 + 300 = 22300 g
Substituting into the above formula, we have;
9500 + B = 22300
B = 22300 - 9500
B = 12800 grams or 12kg 800 grams
