Answer:
El ángulo de 750º es coterminal con los ángulos de 29.88º y 389.88º.
Step-by-step explanation:
Antes de comenzar este enunciado, cabe recordar que dos ángulos en posición estándar son coterminales cuando tiene un lado terminal común, además que el sistema sexagesimal tiene un período de 360º, entonces todo ángulo satisface la siguiente condición:
[tex]\theta = 360\cdot x[/tex], [tex]\forall \,x \in \mathbb{R}[/tex].
Si sabemos que [tex]\theta = 750^{\circ}[/tex], el múltiplo [tex]x[/tex], que indica el número de revoluciones dadas es:
[tex]x =\frac{\theta}{360}[/tex]
[tex]x = \frac{750^{\circ}}{360^{\circ}}[/tex]
[tex]x = 2.083[/tex]
El número de ángulos coterminales equivale al número entero de revoluciones. Y la posición coterminal más pequeña queda determinada por el residuo, que es igual a la diferencia entre el total de revoluciones (2.083) y el número de revoluciones enteras. (2) En este caso, existen dos angulos coterminales cuyas magnitudes determinamos a continuación:
[tex]\theta_{1} = (0 + 0.083)\cdot (360^{\circ})[/tex]
[tex]\theta_{1} = 29.88^{\circ}[/tex]
[tex]\theta_{2} = (1 + 0.083)\cdot (360^{\circ})[/tex]
[tex]\theta_{2} = 389.88^{\circ}[/tex]
El ángulo de 750º es coterminal con los ángulos de 29.88º y 389.88º.

A sailor entered a race and made a round trip of 213.709 miles. What is 213.709 rounded to the nearest hundredth?
Which of the following statements explains how you should find 213.709?
A. Since the digit in the hundredths place is less than five, keep the digit in the hundredths place. Then drop the digits on the right.
B. Since the digit in the hundredths place is less than five, keep the digit in the tenths place. Then drop the digit in the hundredths and thousandths places.
C. Since the digit in the thousandths place is greater than or equal to five, increase the digit in the hundredths place by one. Then drop the digit in the thousandths place.
D. Since the digit the hundredths place is less than five, leave the digit in the hundredths place and drop all the numbers on the right.
Answer:
C
Step-by-step explanation:
There was this saying they told me for rounding things. 5 or more, let it soar. 4 or less, let it rest. 9 is greater than or equal to 5, meaning that the digit in the hundredths place will increase by one.

Area of triangle=42, the width is x+3 and the length is 2x+8, find the value of x
Step-by-step explanation:
Area of triangle = 1/2 × the width × the length
42 = 1/2(x+3)(2x+8)
42 = 1/2×2×(x+3)(x+4)
42 = (x+3)(x+4)
(x+3)(x+4) = 42
x² + 7x + 12 = 42
x² + 7x + 12 - 42 = 0
x² + 7x - 30 = 0
(x-3)(x+10) = 0
x = 3, -10
x can't be -10 because the width and the length should be only + values
x = 3
The value of x found by using the area of triangle concept is 3
What is the Area of a Triangle?
The entire area filled by a triangle's three sides on a two-dimensional plane is referred to as the triangle's area. The fundamental equation for a triangle's area is A = 1/2 b × h, where b and h are the product of the triangle's base and height. All triangle shapes, including scalene, isosceles, and equilateral triangles, may be calculated using this formula. It is important to keep in mind that a triangle's base and height are perpendicular to one another.
In the question, It is given that:
Area of triangle = 42.
Width of the triangle = x+3
Length of the triangle = 2x+8;
And, we know that:
Area of triangle = [tex]\frac{1}{2}[/tex]×[tex]lw[/tex]
⇒[tex]42[/tex] = [tex]\frac{1}{2}[/tex]×[tex](x+3)(2x+8)[/tex]
⇒42 = (x+3)(x+4)
⇒(x+3)(x+4) = 42
⇒x² + 7x + 12 = 42
⇒x² + 7x + 12 - 42 = 0
⇒x² + 7x - 30 = 0
⇒(x-3)(x+10) = 0
⇒x = 3, -10
x can't be -10 because the width and the length should be only + values
⇒x = 3
Hence, The value of x is 3.

Let u = 2i + j, v = i + j, and w = i - j. Find scalars a and b such that u= av + bw.
Answer:
1/2 and 3/2Step-by-step explanation:
Given the expression u= av + bw where u = 2i + j, v = i + j, and w = i - j, to find the scalars a and b, we will first substitute the vectors into the expression given as shown;
u= av + bw
2i + j = a( i + j)+b(i-j)
open the parenthesis
2i + j = ai+aj+bi-bj
collect like terms at the right hand side of the equation
2i + j = ai+bi+aj-bj
2i + j = (a+b)i+(a-b)j
compare the coefficient of complex value i and j on both sides
a+b = 2 ............... 1
a-b = 1................. 2
solve the resulting equation simultaneously using elimination method
Subtract both equation from each other.
(a-a) +(b-(-b))= 2-1
0+2b = 1
b = 1/2
Substitue b = 1/2 into equation 2 to get a
From equation 2, a = 1+b
a = 1 + 1/2
b = 3/2
Hence the scalars a and b are 1/2 and 3/2 respectively
[tex]a=\frac{3}{2},b=\frac{1}{2}[/tex]
A complex number is of the form [tex]\boldsymbol{a+ib}[/tex] where [tex]a,b[/tex] are real numbers.
[tex]u=2i+j[/tex]
[tex]v=i+j[/tex]
[tex]w=i-j[/tex]
[tex]u=av+bw[/tex]
So,
[tex]2i+j=a(i+j)+b(i-j)[/tex]
[tex]2i+j=(a+b)i+(a-b)j[/tex]
Therefore,
[tex]2=a+b\\1=a-b[/tex]
Add these equations.
[tex]3=2a\\\frac{3}{2}=a[/tex]
So,
[tex]1=\frac{3}{2}-b\\\\b=\frac{3}{2}-1\\[/tex]
[tex]=\frac{1}{2}[/tex]

Answer:
86°
Step-by-step explanation:
If you draw a line segment AC, it forms the rest of right triangle ACB with the right angle at C. Then angle BAC is the complement of the given angle:
∠BAC = 90° -47° = 43°
The inscribed angle BAC intercepts arc BC, so the arc measure will be double the angle measure.
arc BC = 2·43° = 86°
__
Another way to get there is to realize that arc BCA is 180°, because AB is a diameter. As above, arc AC will be double the measure of inscribed angle ABC, so arc AC has measure 94°.
arc BC = arc ACB - arc AC
arc BC = 180° -94°
arc BC = 86°

The perimeter of a rectangle is 36 feet. If the length is 13, find the width
Answer: 5 feet
Step-by-step explanation: To find the width of the rectangle,
start with the formula for the perimeter, shown below.
Perimeter = 2l + 2w
Since we know the perimeter is 36 and the
length is 13, we have 36 = 2(13) + 2w.
Simplifying on the right, we have 36 = 26 + 2w.
Not subtract 26 from both sides to get 10 = 2w.
Now divide both sides by 2 and 5 = w.
So the with is 5 feet.

Find the sum 32 +33 +34 + 35 + ... + 112 + 113.
Answer:
5945
Step-by-step explanation:
The sum for an arithmetic series is given by the formula:
[tex]S=(x_1+x_k)\cdot\frac{k}{2}[/tex]
Where x₁ is the initial term, x_k is the last term, and k is the number of elements in the series.
From the sequence, we can see that the first term is 32. The last term is 113.
To determine how many elements we have, subtract 113 and 32:
[tex]113-32=81[/tex]
However, we must add 1 to this number since this doesn't include the first term. Thus:
[tex]81+1=82[/tex]
So, there are 82 terms in total.
Therefore, our sum is:
[tex]S=(32+113)\cdot\frac{82}{2}[/tex]
[tex]S=(145)\cdot 41=5945[/tex]
Answer:
5945
Step-by-step explanation:
an = a1 + ( n - 1) 1
a1 = first term
n = number of terms
an = last term
113 = 32 + ( n - 1 ) 1
113 = 32 + n -1
113 = 31 + n
n = 113 - 31
n = 82.
Sn = n/2(a1 + an)
S82 = 82/2 (32 + 113)
S82 = 41 (145)
S82 = 5945.
2x+2=-59 I need help I don’t know the answer
Answer:
x= -30.5
Step-by-step explanation:
In order to solve equations like this, we need to have all the x terms on one side, and all the other terms on the other side. For this equation so far, the x term (2x) is not alone (there is a +2) so we need to move the +2 to the other side to have x by itself. Whatever you do to one side of equation, you must also do to the other side to keep the equation equal. Therefore we can subtract 2 from both sides which moves the two to the other side while keeping the equation equal. In order to move a term to the other side, we must do the operation opposite to what the term has. E.g. +2 is adding 2, so to move it to the other side, we need to subtract 2.
2x +2 -2 = -59 -2
Which cancels out the 2 on the left side and gives us:
2x = -59-2
2x = -61
Then we just need to remove the 2.
In this case, this 2 is being multiplied to the x, so to move it, we will need to divide both sides by 2.
2x/2 = -61/2
which finally gives us:
x = -30.5

Suppose the average yearly salary of an individual whose final degree is a master's is $41 thousand less than twice that of an individual whose final degree is a bachelor's. Combined, two people with each of these educational attainments earn $115 thousand. Find the average yearly salary of an individual with each of these final degrees.
Answer:N/B The amount is in thousands
The total amount earned by a Bachelor's person be $x:
amount earned by a masters person will be $(2x-38)
Total amount earned by the two individuals will be:
x+(2x-38)=115
solving for x we get:
x+2x-38=115
3x=115+38
3x=153
x=153/3
x=51
also:
2x-38=2*51-38=64
therefore we conclude that master's individual earns average of $ 64,000 while the Bachelor's individual earns $51,000.

f(x)=40+4x+x^2 (e) What is the slope of the chord connecting the points (5, f (5)) and (5 + ∆x, f (5 + ∆x)), when ∆x = 5? Really confused on how to do this and what it means
Answer:
19
Step-by-step explanation:
So we have the function:
[tex]f(x)=40+4x+x^2[/tex]
And we want to find the slope of the chord that connects the points (5,f(5)) and (5+Δx, f(5+Δx)).
So first, find the two points.
1) (5,f(5))
Substitute in 5 for x:
[tex]f(x)=40+4x+x^2\\f(5)=40+4(5)+(5)^2[/tex]
Square and multiply:
[tex]f(5)=40+20+25[/tex]
Add:
[tex]f(5)=85[/tex]
So, our first point is (5,85)
2) (5+Δx, f(5+Δx))
Remove the Δx by substituting it with 5. Thus:
[tex](5+\Delta x,f(5+\Delta x))=(5+5,f(5+5))=(10,f(10))[/tex]
Now, substitute in 10 for x. Thus:
[tex]f(10)=40+4(10)+(10)^2[/tex]
Square and multiply:
[tex]f(10)=40+40+100[/tex]
Add:
[tex]f(10)=180[/tex]
So our second point is (10,180).
Now, just find the slope between (5,85) and (10,180) using the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (5,85) be x₁ and y₁ and let (10,180) be x₂ and y₂. Substitute:
[tex]m=\frac{180-85}{10-5}[/tex]
Subtract:
[tex]m=\frac{95}{5}[/tex]
Divide:
[tex]m=19[/tex]
So, the slope that connects the chord is 19.
And we are done :)
