Answer: 206
Step-by-step explanation:
a=3/4, b=-8, c=-2, d=3
-b[a+(c-d)^2]=
-(-8)[3/4+(-2-3)^2]=
8[3/4+(-5)^2]=
8[3/4+25]=
8*3/4 + 200=
24/4 + 200=
6+200=206
First, solve the parentheses:
8[3/4 + -5^2]
Then, solve the exponent:
8[3/4 + 25]

write the slope-intercept form of the equations of the line described
1. through (1,3), perpendicular to y=x-4
2. through (3,1), parallel to y=-x-4
Answers
1. The equation of the perpendicular line is: y = -x + 4
2. The equation of the parallel line is: y = -x + 4
What are the Equations of Parallel and Perpendicular Lines?The equations of two lines that are parallel to each other will have the slope (m), while the equations of two lines that are perpendicular to each other will have slope values that are negative reciprocals of each other.
The slope-intercept form for the equation of a line is, y = mx + b, where b is the y-intercept and m is the slope of the line.
1. The slope (m) of y = x - 4 is 1. The line that is perpendicular to y = x - 4 would have a slope (m) of -1.
Substitute (a, b) = (1, 3) and m = -1 into y - b = m(x - a):
y - 3 = -1(x - 1)
Rewrite in slope-intercept form:
y - 3 = -x + 1
y = -x + 1 + 3
y = -x + 4
2. The slope (m) of y = -x - 4 is -1. The line that is parallel to y = -x - 4 would have a slope (m) of -1.
Substitute (a, b) = (3, 1) and m = -1 into y - b = m(x - a):
y - 1 = -1(x - 3)
Rewrite in slope-intercept form:
y - 1 = -x + 3
y = -x + 3 + 1
y = -x + 4

Answers
The prices in order from greatest to least unit rate is Price A>Price C>Price B.
Given a table that showing different prices for cans of soup as shown in attached image.
Here, we will calculate the price of 1 quantity of each type of soup.
The Price of 3 quantities of soup price A=$3.87
Now, we will find the price of soup A for the 1 quantity.
The Price of 1 quantity of soup price A=$3.87/3=$1.29
The Price of 2 quantities of soup price B=$2.38
Now, we will find the price of soup B for the 1 quantity.
The Price of 1 quantity of soup price B=$2.38/2=$1.19
The Price of 7 quantities of soup price C=$8.75
Now, we will find the price of soup C for the 1 quantity.
The Price of 1 quantity of soup price C=$8.75/7=$1.25

Write the slope-intercept equation of a line that passes through the points (-2, 5) and (6, -4)
Answers
The slope intercept form of a line which passes through the points (-2, 5) and (6, -4) is y = (-9/8)x + 11/4.
According to the question.
A line passes through the two points (-2, 5) and (6, -4).
As we know that, the slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.
So, the slope of the line = -4 -5/(6 + 2) = -9/8
And, the slope intercept form of a line which passes through the points (-2, 5) and (6, -4) is given by
y = (-9/8)x + b
Since, the line passes through (-2, 5) and (6, -4). So, both the points must statisfy the above equation.
⇒ 5 = (-9/8)(-2) + b
⇒ 5 = 9/4 + b
⇒ b = 5 - 9/4
⇒ b = (20 - 9)/4
⇒ b = 11/4
Therefore, the slope intercept form of a line which passes through the points (-2, 5) and (6, -4) is y = (-9/8)x + 11/4.

What is a dot-product?The dot product, also known as the scalar product, is an algebraic operation that takes two sequences of numbers of equal length (often coordinate vectors) and outputs a single number. The dot product of two vectors' Cartesian coordinates is frequently used in Euclidean geometry. Although other inner products can be defined in Euclidean space, it is frequently referred to as the inner product (or, less frequently, projection product) of Euclidean space (see Inner product space for more).
The sum of the products of the matching entries of the two number sequences is the dot product, according to algebra. B, it is the result of adding the cosine of the angle between the two vectors and the Euclidean magnitudes of the two vectors.
The vectors that make up the triangle must first be located. The vertices are subtracted to achieve this.
QP=(2,0,-4)-(1,-3,-2)=(1,3,-2)
PR=(1,-3,-2)-(6,-2,-5)=(-5,-1,3)
RQ=(6,-2,-5)-(2,0,-4)=(4,-2,-1)
QP.PR = (1, 3, -2).(-5, -1, 3) = -5-3-6= -14
PR.RQ = (-5, -1, 3).(4, -2, -1) = -20+2-3 = -21
RQ.QP = (4, -2, -1).(1, 3, -2) = 4-6+2 = 0
Calculate the dot products to see if these vectors are perpendicular now.
They are perpendicular if the dot product of two vectors equals zero. As you can see, RQ.QP is zero in your triangle, which supports this. Consequently, a right-angled triangle results.

Find the degree measure of each angle in the triangle
Answers
The degree measure for angle B is 28° and angle D is 62°.
We are given that:
∠ C = 90°
∠ B = ( 2 x + 10 )°
∠ D = ( 5 x + 17 )°
Now, using the angle sum property of a triangle, we get that:
∠B + ∠ C + ∠ D = 180°
Substituting the values:
2 x + 10 + 90 + 5 x + 17 = 180
7 x + 117 = 180
7 x = 63
x = 63 / 7
x = 9
∠ B = ( 2 x + 10 )
∠ B = 2(9) + 10
∠ B = 18 + 10
∠ B = 28°
∠ D = ( 5 x + 17 )
∠ D = 5 (9) + 17
∠ D = 45 + 17
∠ D = 62°
Therefore, the degree measure for angle B is 28° and angle D is 62°.

Answers
The equation to represent the relationship between Distance and Time will be 52y = x, where Speed remains constant
In the given question, it is said that the train runs along a distance of 156 miles, which takes 3 hours to complete.
The equation that represents the relationship between Speed, Distance, and Time is as follows :
=> Speed = Distance/Time
It is also stated that the train runs at the same speed so the Speed will be constant while deriving the relationship between Distance and Time.
First, we have to find the speed of the train with the given Distance & Time by the formula => S = D/T, where Speed = S, Distance = 156 miles, and Time = 3 Hours
=> S = 156/3 => S = 52 miles/hour
As we got our constant speed for the train, We can now find out the Distance Time relation of the train. By taking Distance = x, Time = y, Speed = 52 miles/hour
=> 52 = x/y => 52y = x
Hence, we get the relationship between Distance and Time where Speed is constant at 52 miles/hour

To calculate the mean weight of 50 people, add the 50 weights together and divide by 50. To find the median weight of the 50 people, order the data, and find the number that splits the data into two equal parts.
