Keiko sold 3 less than three-fourths of his sister’s sales. Which expression represents what Keiko sold?
5 divided by 2 1/7
Simplest form
Answer: 2 1/3
Step-by-step explanation:
We first convert this to mixed number: 5/1 / 15/7
Then cross cancel and factor to get 7/3.
Lastly we convert this back to a mixed number.
So we get 2 1/3 or 0.667 (decimal)
Given that Cos0=5/13,find a)Tan0,b)Sin0,c)Sec0,d)Co sec0,e)Cot0,
cos θ = Adjacent/ hypotenuse
cosθ= 5/13
a²+b²= c²
a² + 5² = 13²
a² = 13² - 5²
a² = 144
a=√144
a= 12
a is the opposite = 12
b is the Adjacent = 5
c is the hypotenuse = 13
a) tan θ= opposite/Adjacent
tan θ = 12/5
b) sin θ= opposite/ hypotenuse
sinθ= 12/13
C) sec θ= hypotenuse / Adjacent
sec θ= 13/5
d) cscθ= hypotenuse /opposite
cscθ= 13/12
e) cotθ=Adjacent/ opposite
cotθ= 5/12

Answer:
[tex] \frac{0.75x - 3}{x - 1} [/tex]
Step-by-step explanation:
Equation of a rational function is
[tex] \frac{p(x}{q(x)} [/tex]
where q(x) isn't zero.
There is a vertical asymptote at
[tex]x = 1[/tex]
So this mean that our denomiator must have a zero that occur at x=1.
That zero is
[tex]x - 1[/tex]
So our denomiator is
[tex] \frac{p(x)}{x - 1} [/tex]
Since our horinzontal asymptote is a non zero value, the numerator must be a linear equation as well.
So our rational function is
[tex] \frac{ax + b}{x - 1} [/tex]
We know the graph pass through (0,3)
So if we apply that logic,
[tex] \frac{a(0) + b}{0 - 1} = 3[/tex]
[tex] \frac{b}{ - 1} = 3[/tex]
[tex]b = - 3[/tex]
And it passes through (4,0)
[tex] \frac{a(4) + b}{3} = 0[/tex]
[tex]4a + b = 0[/tex]
[tex]4a + ( - 3) = 0[/tex]
[tex]4a = 3[/tex]
[tex]a = \frac{3}{4} [/tex]
So our rational equation is
[tex] \frac{0.75x - 3}{x - 1} [/tex]
The rate of decay in the mass, M, of a radioactive substance is given by the differential equation dM dt equals negative 1 times k times M , where k is a positive constant. If the initial mass was 150g, then find the expression for the mass, M, at any time t
Using separation of variables, it is found that the expression for the mass, M, at any time t, is given by:
[tex]M(t) = 150e^{-kt}[/tex]
What is separation of variables?In separation of variables, supposing a differential equation in the format [tex]\frac{dy}{dx}[/tex], we place all the factors of y on one side of the equation with dy, all the factors of x on the other side with dx, and integrate both sides.
In this problem, the differential equation is:
[tex]\frac{dM}{dt} = -kM[/tex]
Then, applying separation of variables:
[tex]\frac{dM}{M} = -k dt[/tex]
[tex]\int \frac{dM}{M} = \int -k dt[/tex]
[tex]\ln{M} = -kt + C[/tex]
[tex]M(t) = M(0)e^{-kt}[/tex]
The initial mass is of M(0) = 150, hence:
[tex]M(t) = 150e^{-kt}[/tex]

A model of a car is made to a scale of 1.10. What is the ratio of the volumes of the model car to the real car? If the model car has a mass of 2.1 kg: what is the mass of the real car assuming the same metal is used?
Answer:
1:1000
2,100 kg
Step-by-step explanation:
A linear scale of 1:10 means a volume scale of 1:1000.
The ratio of the volumes is model:real = 1:1000.
The mass is proportional to the volume.
The real car has a volume 1000 times the volume of the model, so its mass is also 1000 times the mass of the car.
mass of real car = 1000 × 2.1 kg = 2100 kg

What is the equation of the line that passes through the point (4,1) and has a slope
of 1/2
Linear equations are usually organized in slope-intercept form, which looks like this:
[tex]y=mx+b[/tex]
m is the slope of the lineb is the y-intercept (the value of y when the line passes through the y-axis)To find the equation of a line in slope-intercept form:
Determine the slope of the linePlug the slope into the general formDetermine the y-intercept by solving for b Plug b back into the equationSolving the QuestionWe're given:
m = [tex]\dfrac{1}{2}[/tex](4,1) falls on the lineFirst, plug the given slope into the slope-intercept form equation:
[tex]y=mx+b\\\\y=\dfrac{1}{2}x+b[/tex]
Now, determine the y-intercept.
[tex]y=\dfrac{1}{2}x+b[/tex]
⇒ Plug in the given point (4,1) and solve for b:
[tex]1=\dfrac{1}{2}(4)+b\\1=2+b\\b=-1[/tex]
⇒ Therefore, the y-intercept is -1. Plug this back into our original equation:
[tex]y=\dfrac{1}{2}x-1[/tex]
Answer[tex]y=\dfrac{1}{2}x-1[/tex]

Write an equation of a parabola that opens upward, has a vertex at the origin, and a focus at (0, 2).
Answer:
Parabola opens upwards, so it's a vertical parabola. Vertex at origin (0,0) and focus at (0,2). Standard equation of this parabola is
| (X — h)^2 = 4p(Y — k) |
Focus is at (0,2), so distance between vertex and focus, which is p is 2 units. So 4p = 8 units.
So the equation of this parabola is,
(X — 0)^2 = 8(Y — 0)
X^2 = 8Y or Y = X^2/8

Right pentagonal prism. The height of the prism is 8 ft. The base has two pairs of parallel sides. The sides are consecutively labeled 5 ft, 3 ft, 5 ft, 2 ft, and 7 ft. The parallel sides are those labeled 3 ft and 7 ft, and 5 ft and 2 ft.
The amount of material needed for the containers is its surface area
The amount of material needed for the 8 containers using the assumed parameters is 3080 square feet
How to determine the amount of material?The question is incomplete, as the figure of the right pentagonal prism is not given.
So, I will provide a general explanation.
The surface area (SA) of a right pentagonal prism is:
SA = 5b(a + h)
Where:
b represents the base lengtha represents the apothemh represents the heightFrom the question, we have the height of the prism to be 8 ft.
Assume that:
a = 3 ft and b = 7 ft
The equation becomes
SA = 5 * 7 * (3 + 8)
Evaluate the product
SA = 385
The amount of material needed for the 8 containers would be:
Amount = 8 * 385 square feet
Amount = 3080 square feet
Hence, the amount of material needed for the 8 containers using the assumed parameters is 3080 square feet

We have the following point:-
