y =
x + []
Answer:
y = 1/3x + 1
Step-by-step explanation:
Answer:[tex]y = \frac{1}{3}x +1[/tex]
Step-by-step explanation:
I can see that one coordinate is (0,1) and another to assume is (-3,0)
With this we can make the equation
Equation format is y = mx + b
b is y-intercept, so when x is 0, y = 1, so b = 1
y = mx + 1
We can substitute (-3,0) into the equation and get 0 = -3m + 1
Solving for m gives us [tex]\frac{-1}{-3} = m[/tex]
so [tex]y = \frac{1}{3}x +1[/tex]
The fulcrum of a lever is the point on which it turns. based on the function, how many pounds of force are needed to lift the rock if the distance from the fulcrum is 6 feet? pounds of force
The amount of force that is required to lift the rock if the distance from the fulcrum is 6 feet is 10 lb of force.
Calculations and Parameters:Based on the given graph, we can see the curve passing through the point (1.5,40), (2,30), (2.5,24), (3,20), and (4,15).
These points satisfy by the equation
y= 60/x
and,
x is the distance in feet from the fulcrum y is needed force in pounds.If we input the value of x into the equation,
y= 60/6
= 10 lbs of force.

Step-by-step explanation:
A 5kg sample of plutonium-239 has a half-life of 21,400 years by emitting a 5.157 mev (million or mega electron volts) alpha particles. assume that the rate of decay is constant, how long will it take for the sample to degrade to 4.5kg?
Using an exponential function, it is found that it will take 3,252 years for the sample to degrade to 4.5kg.
What is the exponential function for the amount of a substance?It is given by:
[tex]A(t) = Pe^{-kt}[/tex]
In which:
P is the initial amount. k is the decay rate, as a decimal.The half-life is of 21,400 years, hence, A(21400) = 0.5P, and this is used to find k.
[tex]A(t) = Pe^{-kt}[/tex]
[tex]0.5P = Pe^{-21400k}[/tex]
[tex]e^{-21400k} = 0.5[/tex]
[tex]\ln{e^{-21400k}} = \ln{0.5}[/tex]
[tex]-21400k = \ln{0.5}[/tex]
[tex]k = -\frac{\ln{0.5}}{21400}}[/tex]
k = -0.00003239005
Hence, considering the initial mass is of P = 5 kg, the amount after t years is given by:
[tex]A(t) = 5e^{-0.00003239005t}[/tex]
The amount will be of 4.5 kg at t for which A(t) = 4.5, hence:
[tex]4.5 = 5e^{-0.00003239005t}[/tex]
[tex]e^{-0.00003239005t} = 0.9[/tex]
[tex]\ln{e^{-0.00003239005t}} = \ln{0.9}[/tex]
[tex]-0.00003239005t = \ln{0.9}[/tex]
[tex]t = -\frac{\ln{0.9}}{0.00003239005}[/tex]
t = 3252.

Can anyone help solve this step by step?
Answer:
85.2 m²
Step-by-step explanation:
Perhaps one of the easiest ways to decompose this composite figure is to consider it as a rectangle with a triangle removed from it.
__
The vertical dimension of the missing triangle is 8-4 = 4 m. The horizontal dimension of the missing triangle is 11.4 -8.4 = 3 m. The overall rectangle, including the missing triangle, is 11.4 m wide and 8 m high.
The area of the figure is ...
area = rectangle area - triangle area
= (11.4 m)(8 m) -1/2(4 m)(3 m) = 91.2 m² -6 m² = 85.2 m²
The area of the shape is 85.2 square meters.

Additional comment
The area of a rectangle is the product of its length and width:
A = LW
The area of a triangle is half the product of its base and height:

If y varies directly as x and x=3 when y=12, find x when y=3
Answer:
Answer:
y = 4x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 3 when y = 12
k = = = 4
y = 4x ← equation of variation

If six pounds of pinto beans, priced at $2.00 per pound, are combined with four pounds of lima beans, priced at $3.00 per pound, what is the per-pound price of the resulting bean mix
The per-pound price of the mix must be: P = $2.40 per lb.
What is the per-pound price of the resulting bean mix?
To get it, we need to take the total amount of money used in the mix, and divide it by the mass of the mixture that we get.
We will use 6lb of pinto beans, where each lb costs $2.00, so the total cost of this part is:
6*$2.00 = $12.00
We also use 4 lb of lima beans, where each pound costs $3.00, so the total cost of this part is:
4*$3.00 = $12.00
Then the total cost of the mix is $12.00 + $12.00 = $24.00
And the the mix has a total mass of 6lb + 4lb = 10lb
Then the per-pound price of the mix must be:
P = $24.00/10lb = $2.40 per lb.

Please answer ! Polynomials and Factoring problems. Thank you!
Answer: The answer to your first question is b^2+2b-8. You second answer is y^2-4y+3.
Step-by-step explanation: Now, these questions deal with the FOIL method commonly taught in schools. The FOIL method is to turn factored binomials back into quadratics. Let's first go over what FOIL means.
F - First. So you multiply the first terms in each set of parenthesis, so b times b and y times y make b squared and y squared.
O - Outer. Multiply the two outer terms together, so b times -2 and y times -3. Remeber to pay attention to your signs when you multiply during these probelms!
I- Inner. Multiply the two inner terms together. so 4 times b and -1 times y. Again, make sure the signs are incorporated!
L - Last. Multiply the last terms in the binomials. So 4 times -2 and -1 times -3.
Now that we have our numbers, we have expanded quadratics that look like these:
b^2 -2b+4b-8 and y^2-3y-y+3
Now combine the two middle terms into +2b and -4y, and your answers are b^2+2b-8 and y^2-4y+3.
