Mackenzie was offered a job that paid a
salary of $45,000 in its first year. The
salary was set to increase by 5% per year
every year. If Mackenzie worked at the job
for 17 years, what was the total amount of
money earned over the 17 years, to the
nearest whole number?
Answer:
103,140.82, or 103,141 since it asks for the whole number.
Step-by-step explanation:
[tex]45000(1.05)^17[/tex]
the 17 is supposed to be the whole power, not sure why the 7 is lower. but since she is making 45k a year, at a 5% increase in wages per year, this is how we would set up the equation. the number, multiplied by the percentage which is written as 1.05, since it is an increase, not a decrease, then we set that to the power of 17 since it is 17 years.

How do i write 2x+3y=24 as slope-intercept form?
Answer:
y = - [tex]\frac{2}{3}[/tex] x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = 24 ( subtract 2x from both sides )
3y = - 2x + 24 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + 8 ← in slope- intercept form
The equation 2x+3y=24 in the slope-intercept form can be written as [tex]y = -\frac{2}{3}x+8[/tex]
From the question,
We are to write the given equation in the slope-intercept form
The slope-intercept form of an equation of straight line is written as
y = mx +c
To write the equation, 2x+3y=24, in the slope-intercept form, we will make y the subject of the equation
[tex]2x+3y=24[/tex]
First, subtract 2x from both sides of the equation
That is,
[tex]2x -2x +3y = 24 -2x[/tex]
This becomes
[tex]3y = 24 -2x[/tex]
Now, divide both sides by 3
[tex]\frac{3y}{3} =\frac{24-2x}{3}[/tex]
∴ [tex]y = \frac{24}{3}-\frac{2x}{3}[/tex]
[tex]y = 8-\frac{2}{3}x[/tex]
In the slope-intercept form, we get
[tex]y = -\frac{2}{3}x+8[/tex]
Hence, the equation 2x+3y=24 in the slope-intercept form can be written as [tex]y = -\frac{2}{3}x+8[/tex]

Does a right triangle exist where sin A = sin B = cos A = cos B, where A and B are the two acute angles of the triangle? Provide evidence to support your conclusion, and if possible, find the measures of angles A and B.
Answer:
Step-by-step explanation:
When you list the trigonometic ratios for both acute angles in a right triangle, you notice some interesting developments.
Let's concentrate on sine and cosine:
Observation from the table above: notice1
In a right triangle, the sine of one acute angle, A, equals the cosine of the other acute angle, B.
If ∠A and ∠B are the acute angles of a right triangle,
sin A = cos B
Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary. ∠A is the complement of ∠B, and ∠B is the complement of ∠A.
If we write, m∠B = 90º - m∠A (or m∠A = 90º - m∠B ), and we substitute into the original observation, we have:
notice4
If θ is substituted for m∠A , we establish the following relationship between sine and cosine:
sincosrule
The sine of any acute angle is equal to the cosine of its complement.
The cosine of any acute angle is equal to the sine of its complement.
Sine and cosine are called "cofunctions", where the sine (or cosine) function
of any acute angle equals its cofunction of the angle's complement.
FYI: What about tangent?
Yes, there is a "relationship" regarding the tangent of the two acute angles (A and B) in a right triangle. It is not, however, the same type of relationship that exists between sine and cosine.
The tangent of ∠A is the reciprocal (flip over) of the tangent of ∠B.
The angles being used in the following examples are acute angles.
ex1
If sin 30º = ½ and cos θ = ½,
find θ. Solution: Since both trig functions = ½,
30º and θ must be complementary.
θ = 60º
ex2
If sin(3x + 10)º = cos(x + 24)º,
find x. Solution: In order for the sine and cosine to be equal, the angles must be complementary.
3x + 10 + x + 24 = 90
4x + 34 = 90
4x = 56
x = 14
ex3
If sin(15º) = 0.26 and
cos (15º) = 0.97,
find sin(75º) and the cos(75º). Solution: The sine of an angle and the cosine of its complement are equal.
15º and 75º are complementary.
sin(75º) = cos(15º) = 0.97
cos(75º) = sin(15º) = 0.26
ex4
In right ΔABC, m∠C = 90º,
sin A = x + 0.1 and cos B = 2x - 0.4. Find x. Solution: If A and B are the acute angles of a right triangle, sin A = cos B.
x + 0.1 = 2x - 0.4
0.5 = x

Answer: 2016 in^2
Step-by-step explanation:
3) Let's start with the taller rectangular prism. The height is 24", the width is 12", and the length is 12". The smaller rectangular prism is actually a cube because the height, width, and length are all 12". Just as a refresher, the surface area of an object is only the area of each outside face. For rectangular prisms, the surface area is 2(lh+wh+lw) (l=length, h=height, w=width). And for cubes, the surface area is 6s^2, where s is the side. 2(12*24+12*24+12*12) is equal to 1440 inches squared, however, half of one face is covered. This is the longest face shaded in dark green: 24" times 12", but because only half is showing, it is 24*12 divided by 2. This is equal to 144"; and you must subtract this from the entire surface area to account for that covered space. 1440-144 is 1296 inches squared. The cube is (12*12)(6) which is 864. But one whole side is covered, meaning you need to subtract 144 to have the surface area be 720 inches squared. 1296 plus 720 is 2016 inches squared. Decounting the half a side from the prism and one full side from the cube, there are only 10 and a half sides shown.

Q1: No solutions
Q2: x=2, y=-2
Q3: x=1, y=4
Step-by-step explanation:
Q1: Found out 0y = 18 which is impossible therefore no solution.
Q2:
In the first equation: [tex]2x - 4y = 12[/tex]
Let's express x in terms of y by changing the subject. Follow my steps.
[tex]2x = 12+4y[/tex]
[tex]x = \frac{12+4y}{2}[/tex]
Now let's put the x above into the second equation: [tex]-14x-4y=-20[/tex]
It becomes: [tex]-14(\frac{12+4y}{2})-4y=-20[/tex]. Follow my steps.
[tex]-7(12+4y)=-20+4y[/tex]
[tex]-84-28y=-20+4y[/tex]
[tex]-32y=64[/tex]
[tex]y=-2[/tex]
Put y = -2 into the first equation:
[tex]2x-4(-2)=12[/tex]
[tex]2x+8=12[/tex]
[tex]2x=12-8[/tex]
[tex]2x=4[/tex]
[tex]x=2[/tex]
Q3:
Multiply the first equation by 3 and the second equation by 7, so that both are 21x.
1st equation:
[tex]3(7x-3y)=3(-5)[/tex]
[tex]21x-9y=-15[/tex]
2nd equation:
[tex]7(3x+2y) = 7(11)[/tex]
[tex]21x+14y = 77[/tex]
We can now substract the 2nd equation with the 1st equation so that both 21x cancels out and only the variable y remains.
[tex]21x-9y-(21x+14y)=-15-77[/tex]
[tex]21x-9y-21x-14y=-92[/tex]
[tex]-23y=-92[/tex]

Write g(x) = 40x 4x2 in vertex form. Write the function in standard form. Factor a out of the first two terms. Form a perfect square trinomial. Write the trinomial as a binomial squared. G(x) = 4x2 40x g(x) = 4(x2 10x) (ten-halves) squared = 25 g(x) = 4(x2 10x 25) – 4(25) g(x) = (x )2 –.
The vertex form of the function g(x)=40x-4x² is g(x) = 4(x + 5)² - 100, where the vertex lies at (-5, -100).
What is the Equation of a parabola?The general equation of a parabola is given as,
y = a(x-h)² + k
where,
(h, k) are the coordinates of the vertex of the parabola in form (x, y);
a defines how narrower is the parabola, and the "-" or "+" that the parabola will open up or down.
As we want to write a function g(x) = 40x + 4x² in vertex form, and we know that the vertex form of a parabola, with vertex at (h,k) is written as,
[tex]f(x) = a(x-h)^2 + k[/tex]
Also, the algebraic identity [tex](x + a)^2[/tex] is written as,
[tex](x + a)^2 = x^2 + 2ax + a^2[/tex],
Therefore, [tex]x^2 + 2ax[/tex] can be written as
[tex]x^2 + 2ax = (x + a)^2 - a^2[/tex]
Further, we try to write the g(x) in the vertex form it can be written as,
[tex]\begin{aligned}g(x) &= 4x^2 + 40x\\\\ &= 4[x^2 + 10x]\\\\ &= 4[(x + 5)^2 - 5^2]\\\\ &= 4(x + 5)^2 - 100\\\end{aligned}[/tex]
Hence, the vertex form of the function g(x)=40x-4x² is g(x) = 4(x + 5)² - 100, where the vertex lies at (-5, -100).

The students in Suzanne's school are painting a rectangular mural outside the building that will be 15 feet by 45 feet. Scale drawing of the mural is shown. The diagonal is approximately 6.3 units.Write the unit rate for the proportional relationship between lengths on the mural y and lengths in the scale drawing x.
Answer:
The dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53
Step-by-step explanation:
The first step will be to find the diagonal of the rea life mural.
We can use Pythagoras' Theorem to do this.
Diagonal = [tex]\sqrt{15^2 +45^2 }[/tex] =47.43 feet.
Now we have the real-life diagonal, we will now relate the diagonal of the painting outside with the one on paper. We can do this by dividing the two diagonals.
This will be 47.43 / 6.3 units = 7.53.
The scale factor is 7.53
To get the dimensions of the length and the breadth on paper, we divide the outside dimensions by the scale factor.
This will be
Length = 15/ 7.53 = 1.992
Breadth = 45/7.53 = 5.976
Therefore, the dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53
