Answer:
25, 25, 22.5, 22
Step-by-step explanation:
It gives you a hint; K = y/x. They give you what x and y are so use that to solve for the last row.
We are given all of these values:
x -> 2, 3, 4, 5
y -> 50, 75, 90, 110
Use the formula given and solve for K.
50/2 = 25
75/3 = 25
90/4 = 22.5
110/5 = 22

Let f(x) be a continuous function such that f(1)=2 and f(x)= x^3+6 and What is the value of f(5)?(A) 11.446 (B) 13.446 (C) 15.446 (D) 24.672 (E) 26.672 fx x f5
Answer:
the value of f(5) is 26.672
Option (E) 26.672 is the correct answer
Step-by-step explanation:
Given that;
f(1) = 2 and f(x) = √( x³ + 6 )
f(5) = ?
f(5) = f(1) + ₁∫⁵ f'(x) dx
we substitute
f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx
f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx
f(5) = 2 + 24.6719
f(5) = 26.672
Therefore the value of f(5) is 26.672
Option (E) 26.672 is the correct answer
The value of f(5) is 26.672
Continuous functions and drivativesGiven the following parameters
f(1) = 2
f(x) = √( x³ + 6 )
We need to calculate the value of f(5) as shown below
f(5) = f(1) + ₁∫⁵ f'(x) dx
Substitute the given parameters
f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx
f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx
f(5) = 2 + 24.6719
f(5) = 26.672
Hence the value of f(5) from the solution is 26.672

Adrian has a bag full of pebbles that all look about the same. He weighs some of the pebbles and finds that their weights are normally distributed, with a mean of 2.6 grams and a standard deviation of 0.4 grams.
What percentage of the pebbles weigh more than 2.1 grams? Round to the nearest whole percent.
Answer:
89% of pebbles weigh more than 2.1 grams.
Step-by-step explanation:
Given that
Mean = 2.6
SD = 0.4
As we have to find the percentage of pebbles weighing more than 2.1, we have to find the z-score for 2.1 first
[tex]z = \frac{x-mean}{SD}\\z = \frac{2.1-2.6}{0.4}\\z = -1.25[/tex]
Now we have to use the z-score table to find the percentage of pebbles weighing less than 2.1
So,
[tex]P(x<-1.25) = 0.10565[/tex]
This gives us the probability of P(z<-1.25) or P(x<2.1)
To find the probability of pebbles weighing more than 2.1
[tex]P(x>2.1) = 1 - P(x<2.1) = 1 - 0.10565 = 0.89435[/tex]
Converting into percentage
[tex]0.89435*100 = 89.435\%[/tex]
Rounding off to nearest percent
89%
Hence,
89% of pebbles weigh more than 2.1 grams.

Answer:
On a coordinate plane, a point is 3 units to the left and 5 units up. Another point is 4units to the right and 3 units down
Step-by-step explanation:
The coordinate plane is a plane formed from the intersection of the x axis (horizontal line) and y axis (vertical line). The point of intersection of these axis is known as the origin. A point can be represented on the coordinate plane using the x and y coordinates.
The x axis is to the left and right of the origin, negative points are to the left of the origin while positive points are to the right of the origin. The y axis is to the up and down of the origin, negative points are to the down of the origin while positive points are to the up of the origin.
A point in the coordinate plane is represented as (x, y).
The location of point (-3,5) is 3 units to the left and 5 units up while point (4, -3) is 4units to the right and 3 units down
Is my answer correct?
Answer:
It's wrong. The correct answer is -3 1/8x + 6 3/10
Step-by-step explanation:
You don't need to do the first two numbers of each equation but you want to consider the last part of the equation since each of them is different. Convert 2 1/5 to 2 2/10 to make it easier. Because you are subtracting two negative numbers, they will actually add so 2 2/10 + 4 1/10 equals 6 3/10 which makes the second option applicable.

The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net exports are obtained by subtracting total imports from total exports; a negative net export means the country imported more goods than it exported.
Net Exports (Billions of dollars) United States Denmark China Germany Spain -150 -100 150 -50 050 100 Net Exports (Billions of dollars)
What is the difference between the net exports from The United States and Denmark?
a. 70 billion dollars
b. 80 billion dollars
c. 90 billion dollars
d. -140 billion dollars
Answer:
$80 billion
Step-by-step explanation:
From the graph, we have the following:
[tex]United\ States = -110[/tex]
[tex]Denmark = -30[/tex]
[tex]China = 120[/tex]
[tex]Germany = 40[/tex]
[tex]Spain = 30[/tex]
Required
Determine the difference in US and Denmark exports
The difference is calculated as thus:
[tex]Difference = Denmark - United\ States[/tex]
This gives:
[tex]Difference = -30 - (-110)[/tex]
[tex]Difference = -30 +110[/tex]
[tex]Difference = 80[/tex]
Hence, the difference is $80 billion

What is Linear Equation in 1 variable?
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution
Given data ,
The equation is x + 7/2 = 5x/3
Subtracting 7/2 on both sides , we get
x = 5x/3 - 7/2
x = ( 10x - 21 ) / 6
Multiplying 6 on both sides , we get
6x = 10x - 21
Adding 21 on both sides , we get
6x + 21 = 10x
Subtracting 6x on both sides , we get
4x = 21
Divide by 4 on both sides , we get
x = 21/4
Hence , the solution for x + 7/2 = 5x/3 is x = 21/4

A. With these dimensions, the area would be 18 sq units
1 * 18 = 18
B. With these dimensions, the area would be 18 sq units
3 * 6 = 18

At time t ≥ 0, the velocity of a body moving along the s-axis is v = t² -5t +4. When is the body moving backwards
Check comments for multiple choice answers
Answer:
A
Step-by-step explanation:
The velocity of a moving body is given by the equation:
[tex]v=t^2-5t+4 ,\, t\geq0[/tex]
Is the velocity is positive (v>0), then our object will be moving forwards.
And if the velocity is negative (v<0), then our object will be moving backwards.
We want to find between which interval(s) is the object moving backwards. Hence, the second condition. Therefore:
[tex]v<0[/tex]
By substitution:
[tex]t^2-5t+4<0[/tex]
Solve. To do so, we can first solve for t and then test values. By factoring:
[tex](t-4)(t-1)=0[/tex]
Zero Product Property:
[tex]t=1, \text{ and } t=4[/tex]
Now, by testing values for t<1, 1<t<4, and t>4, we see that:
[tex]v(0)=4>0,\, v(2)=-2<0,\,\text{ and } v(5)=4>0[/tex]
So, the (only) interval for which v is <0 is the second interval: 1<t<4.
Hence, our answer is A.
The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 47 and a standard deviation of 7. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 47 and 68
Answer:
[tex]P(-2<Z<2)=95\%[/tex]
Step-by-step explanation:
From question we are told that
Sample mean [tex]\=x= 47[/tex]
Standard deviation [tex]\sigma =7[/tex]
Generally the X -Normal is given as
[tex]Z=\frac{x-\=x}{\sigma}[/tex]
[tex]Z=\frac{x-47}{9}[/tex]
Analyzing the range
[tex]P(47<x<65) = P(0< z<2.00)[/tex]
[tex]P(47<x<65) = 95/2[/tex]
[tex]P(47<x<65) = 47.5\%[/tex]
Mathematically
[tex]Z_1 =\frac{47-47}{9} =0[/tex]
[tex]Z_2 =\frac{65-47}{9} =2[/tex]
Empirical rule shows that
[tex]P(-2<Z<2)=95\%[/tex]

Answer:
Product for A = 046
Product for B = 0230
Sum for C = 0.0276
