Help please!! Thanks
Answer:
A
Step-by-step explanation:
First, let's label the variables:
[tex]\text{Let }x \text{ represent Kaylee's number of pens,}\\\text{Let }L \text{ represent Lou's number of pens,}\\\text{And let }I \text{ represent Ilene's number of pens.}[/tex]
The first and second sentence, Kaylee at the start has x pens. She gave half to Lou, who started out with two fewer than Kaylee.
In other words, the total Lou now has is:
[tex]L=(\frac{1}{2}x )+(x-2)[/tex]
The first term represents what Kaylee gave to Lou. The second term represents what Lou had originally (two fewer than Kaylee [x]).
Simplifying, we get:
[tex]L=\frac{3}{2}x-2[/tex]
Third sentence. Lou give half of his new total to Ilene, who started out with three fewer pens than Lou. Lou, remember, started with three fewer than Kaylee (x-2). In other words:
[tex]I=(\frac{1}{2}(\frac{3}{2}x-2) )+((x-2)-3)[/tex]
The left represents what is given to Ilene: one-third of Lou's new total. The right represents Ilene's original total: three fewer than Lou: or five fewer than Kaylee. Simplifying gives:
[tex]I=(\frac{3}{4} x-1)+(x-5)\\I=\frac{7}{4}x-6[/tex]
Finally, Ilene gives a third of this new amount to Kaylee, and Kaylee's final amount is 37. Thus:
[tex]37=x-\frac{1}{2}x+\frac{1}{3}(\frac{7}{4}x-6)[/tex]
The first term represents what Kaylee originally started with. The second term represents what she gave to Lou. And the third term represents what Ilene gave to Kaylee. Simplify:
[tex]37=\frac{1}{2}x+\frac{7}{12}x-2\\39=\frac{6}{12}x+\frac{7}{12}x \\39=\frac{13}{12}x\\ 468=13x\\x=36[/tex]
Manuela solved the equation 3−2|0.5x+1.5|=2 for one solution. Her work is shown below. 3−2|0.5x+1.5|=2 −2|0.5x+1.5|=−1 |0.5x+1.5|=0.5 0.5x+1.5=0.5 0.5x=−1 x=−2 What is the other solution to the equation? x=−6 x=−4 x=2 x=4
Answer:
Step-by-step explanation:
We'll just work on solving both so you can see what's involved in solving an absolute value equation. Because an absolute value is a distance, we can have that distance being both to the right on the number line of the number in question or to the left. For example, from 2 on the number line, the numbers that are 5 units away are 7 and -3. Using that logic, we will simplify the equation down so we can set up the 2 basic equations needed to solve for x.
If [tex]3-2|.5x+1.5|=2[/tex] then
[tex]-2|.5x+1.5|=-1[/tex] What you need to remember here is that you cannot distribute into a set of absolute values like you would a set of parenthesis. The -2 needs to be divided away:
[tex]|.5x+1.5|=.5[/tex]
Now we can set up the 2 main equations for this which are
.5x + 1.5 = .5 and .5x + 1.5 = -.5
Knowing that an absolute value will never equal a negative number (because absolute values are distances and distances will NEVER be negative), once we remove the absolute value signs we can in fact state that the expression on the left can be equal to a negative number on the right, like in the second equation above.
Solving the first one:
.5x = -1 so
x = -2
Solving the second one:
.5x = -2 so
x = -4
We want to find the other solution of the given absolute value equation.
The other solution is x = -4
We know that:
3 - 2*|0.5*x + 1.5| = 2
It has one solution given by:
- 2*|0.5*x + 1.5| = 2 - 3 = -1
|0.5*x + 1.5| = 0.5
0.5*x + 1.5 = 0.5
0.5*x = 0.5 - 1.5 = -1
0.5 = -1/x
Then we have x = -2
To get the other solution we need to remember that an absolute value equation can be written as:
|x - a| = b
or:
(x - a) = b
(x - a) = -b
Then the other solution to our equation comes from:
|0.5*x + 1.5| = 0.5
(0.5*x + 1.5) = -0.5
0.5*x = -0.5 - 1.5 = -2
x = -2/0.5 = -4
The other solution is x = -4

if the second angle is 20% more than the first angle and the third angle is 20% less than the first angle in a triangle, then find the three angles of the triangle
Answer:
Step-by-step explanation:
If the second angle's measure is based on the first angle's measure, and the third angle's measure is also based on the first angle's measure, then the first angle is the main angle. We will call that x.
1st angle: x
2nd angle: x + 20%
3rd angle: x - 20%
By the Triangle Angle-Sum Theorem, all those angles will add up to 180, so:
x + (x + 20%) + (x - 20%) = 180 and
3x = 180 so
x = 60. That means that
2nd angle: 60 + (.2*60) which is
60 + 12 = 72 and
3rd angle: 60 - (.2*60) which is
60 - 12 = 48. Let's check those angles. If
∠1 = 60
∠2 = 72
∠3 = 48,
then ∠1 + ∠2 + ∠3 = 180 and
60 + 72 + 48 does in fact equal 180, so you're done!

Indicate, in standard form, the equation or inequality that is shown by the graph.
Answer:
The equation is y = -x + 4
Step-by-step explanation:
This is a very trivial exercise:
The general equation of a line is given by:
y - y₁ = m(x - x₁)
where m = slope of the linear graph
From the given graph, it can be observed that the coordinate (x₁, y₁) and (x₂, y₂) are (0, 4) and (4, 0)
The slope, m = (y₂ - y₁)/(x₂ - x₁)
m = (0 - 4)/(4 - 0)
m = -4/4
m = -1
Substituting the values of (x₁, y₁) = (0, 4) and m = -1 into the general equation:
y - y₁ = m(x - x₁)
y - 4 = -1 (x - 0)
y - 4 = -x
y = -x + 4

A right-angled triangle has shorter side lengths exactly c^2-b^2 and 2bc units respectively, where b and c are positive real numbers such that cc is greater than b. Find an exact expression for the length of the hypotenuse (in appropriate units).
Answer: hypotenuse = [tex]c^{2} + b^{2}[/tex]
Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side ([tex]s_{1},s_{2}[/tex]) of the right triangle, .i.e.:
[tex]h^{2} = s_{1}^{2} + s_{2}^{2}[/tex]
In this question:
[tex]s_{1}[/tex] = [tex]c^{2}-b^{2}[/tex]
[tex]s_{2} =[/tex] 2bc
Substituing and taking square root to find hypotenuse:
[tex]h=\sqrt{(c^{2}-b^{2})^{2}+(2bc)^{2}}[/tex]
Calculating:
[tex]h=\sqrt{c^{4}+b^{4}-2b^{2}c^{2}+(4b^{2}c^{2})}[/tex]
[tex]h=\sqrt{c^{4}+b^{4}+2b^{2}c^{2}}[/tex]
[tex]c^{4}+b^{4}+2b^{2}c^{2}[/tex] = [tex](c^{2}+b^{2})^{2}[/tex], then:
[tex]h=\sqrt{(c^{2}+b^{2})^{2}}[/tex]
[tex]h=(c^{2}+b^{2})[/tex]
Hypotenuse for the right-angled triangle is [tex]h=(c^{2}+b^{2})[/tex] units
The expression for the length of the hypotenuse is [tex]c^2+ b^2 \ units[/tex].
Given that,
A right-angled triangle has shorter side lengths exactly [tex]c^{2} - b^{2}[/tex] and 2bc units respectively,
Where b and c are positive real numbers such that c is greater than b.
We have to determine,
An exact expression for the length of the hypotenuse?
According to the question,
The Pythagoras theorem states that the sum of the hypotenuse in the right-angled triangle is equal to the sum of the square of the other two sides.
A right-angled triangle has shorter side lengths exactly [tex]c^{2} - b^{2}[/tex] and 2bc units respectively,
Where b and c are positive real numbers such that c is greater than b.
Therefore,
The expression for the length of the hypotenuse is,
[tex]\rm (Hypotenuse)^2 = (c^2-b^2)^2+ (2bc)^2\\\\(Hypotenuse)^2 = c^4+ b^4 - 2c^2b^2 + 4c^2b^2\\\\(Hypotenuse)^2 = c^4+ b^4 +2c^2b^2 \\\\Hypotenuse = \sqrt{c^4+ b^4 +2c^2b^2}\\\\\ Hypotenuse = \sqrt{(c^2+ b^2)^2}\\\\ Hypotenuse = c^2+b^2 \ units[/tex]
Hence, The required expression for the length of the hypotenuse is [tex]c^2+ b^2 \ units[/tex].

the point slope form of the equation of the line that passes through (-5,1 ) and (10,-7) is y +7= - 1/2 (x-10) what is the standard form of the equation for this line ?
Answer:
The standard form of the equation is y = -x/2 -2
Step-by-step explanation:
The standard form of equation of this line is expressing the line in the form;
y = mx + c
So let’s make a rearrangement to what we have at hand;
y + 7 = -1/2(x-10)
2(y + 7) = -1(x-10)
2y + 14 = -x + 10
2y = -x + 10 -14
2y = -x -4
divide through by 2
y = -x/2 -2
A wheel rolling at a constant speed has a radius of 15 inches and takes 30
seconds to roll 100 feet along the ground. What is its angular velocity? Use
3.14 for (pie) , and solve to two decimal places
Answer:
152.87 degree/seconds
Step-by-step explanation:
1 rotation = Circumference of a circle = 2πr
r = 15 inches
1 rotation = 2 × 3.14 × 15
94.2 inches.
We are told in the question that it takes 30 seconds to roll 100 feet along the ground
Convert feet to inches
1 feet = 12 inches
100 feet =
100 × 12 = 1200 inches.
Hence, if
94.2 inches = 1 rotation
1200 inches = X
Cross multiply
94.2 × X = 1200 × 1
94.2X = 1200
X = 1200/94.2
X = 12.738853503 rotations
Formula for Angular velocity = Number of rotations × 2π/time in seconds
Time = 30 seconds
12.738853503 × 2 × 3.14/30
= 2.6666666667 rotations per second
Converting Angular velocity to degree per second
= 2.6666666667 × 180/ π
= 2.6666666667 × 180/3.14
= 152.86624204 degree/seconds
Approximately to 2 decimal places
= 152.87 degree/seconds

A pole that is 2.5 M tall cast a shadow that is 1.72M lawn dart at the same time a nearby tower cast a shadow that is 50.5 M long how tall is the tower round answer to the nearest meter
Answer:
The tower is 73.4 m tall
Step-by-step explanation:
The height of the pole = 2.5 m
The shadow cast by the pole = 1.72 m
Shadow cast by tower = 50.5 m
To find the height of the tower, we proceed by finding the angle of elevation, θ, of the light source casting the shadows as follows;
[tex]Tan\theta =\dfrac{Opposite \ side \ to\ angle \ of \ elevation}{Adjacent\ side \ to\ angle \ of \ elevation} = \dfrac{Height \ of \ pole }{Length \ of \ shadow} =\dfrac{2.5 }{1.72}[/tex]
[tex]\theta = tan ^{-1} \left (\dfrac{2.5 }{1.72} \right) = 55.47 ^{\circ}[/tex]
The same tanθ gives;
[tex]Tan\theta = \dfrac{Height \ of \ tower}{Length \ of \ tower \ shadow} =\dfrac{Height \ of \ tower }{50.5} = \dfrac{2.5}{1.72}[/tex]
Which gives;
[tex]{Height \ of \ tower } = {50.5} \times \dfrac{2.5}{1.72} = 73.4 \ m[/tex]

Simplify the following v^4*v^5*v
Answer:
v^10
Step-by-step explanation:
For this, we need to understand one important rule of exponents. For powers of like bases, you add the exponents when they are being multiplied. With this in mind let's continue.
In this problem, the base is v, each multiplied with different powers. So:
v^4 * v^5 * v = v^(4+5+1) = v^10
So the solution will be v^10.
An additional example would be 2^2 * 2^3.
For this we know it would be 2^2 * 2^3 = 2^(2+3) = 2^5 = 32.
We can verify by simply doing 2 * 2 * 2 * 2 * 2 = 32. Note both are 32, and this example shows the usefulness of exponent rules.

where, [tex]r=\sqrt{a^2+b^2}[/tex] and [tex]\tan \theta=\dfrac{b}{a}[/tex], [tex]\theta[/tex] is called the argument of z, [tex]0\leq \theta\leq 2\pi[/tex].
The given complex number is -5i.
It can be rewritten as
[tex]z=0-5i[/tex]
Here, a=0 and b=-5. [tex]\theta[/tex] lies in 4th quadrant.
[tex]r=\sqrt{0^2+(-5)^2}=5[/tex]
[tex]\tan \theta=\dfrac{-5}{0}[/tex]
[tex]\tan \theta=\infty[/tex]
[tex]\theta=2\pi -\dfrac{\pi}{2}[/tex] [tex][\because \text{In 4th quadrant }\theta=2\pi-\theta][/tex]
[tex]\theta=\dfrac{3\pi}{2}[/tex]

f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The function:
f(x) = 20[tex]e^x[/tex]
If we graph this function we get a similar graph that is shown.
The coordinates of f(x) = 20 [tex]e^x[/tex] are:
To find the coordinates, we need to plug in different values of x into the function and calculate the corresponding y-values.
For example, when x = 0, we have:
f(0) = 20e^0 = 20(1) = 20
So one coordinate on the graph is (0, 20).
Similarly, when x = 1, we have:
f(1) = 20e^1 = 20e = 20(2.71828) ≈ 54.6
So another coordinate on the graph is (1, 54.6).
We can find more coordinates by plugging in other values of x and calculating the corresponding y-values.
Now,
As x increases, the function f(x) grows exponentially, meaning the y-values will increase very rapidly.
Thus,
The function f(x) = 20[tex]e^x[/tex] could have the graph shown.
