Answer:
4) y - 5 = 2 (x -2) ;y = 2 x +1
The equation of the straight line in point - slope form
y - 5 = 2 (x -2)
The equation of the straight line passing through the point (2,5) and having slope m=2
y = 2 x +1
Step-by-step explanation:
Step(i):-
Given that the points are (0,1) and (2,5)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{5-1}{2-0} = \frac{4}{2} = 2[/tex]
Step(ii):-
The equation of the straight line passing through the point (2,5) and having slope m=2
y - y₁ = m(x-x₁)
y - 5 = 2 (x -2)
y -5 = 2x - 4
y = 2x -4+5
y = 2 x +1
Final answer:-
The equation of the straight line in point - slope form
y - 5 = 2 (x -2)
The equation of the straight line passing through the point (2,5) and having slope m=2
y = 2 x +1

You earn $320 in 40 hours. At this rate how many hours do you work to earn $440?
Answer:
60.5
Step-by-step explanation:
320/44=7.27
440/7.27=60.5
Answer: 55 Hours
Step-by-step explanation:
If you take 320 and divide it by 40
you get 8
This means you earn $8 for every hour you work.
Now if you take 440 and divide it by 8, meaning $440 dollars divided by $8
You will get
55, meaning you must work 55 Hours to make $440.

Step-by-step explanation:
Let (x-2y) = x
x^2 -12x +32
Then factor the quadratic polynomial by 2 brackets factoring.
(x-8)(x-4)
Then convert x to (x-2y)
(x-2y-8)(x-2y-4)
The table shows data for a car stopping on a wet road. Stopping distance formula [tex]d(v)=\frac{2.15v^{2} }{64.4f}[/tex]
Determine the value of f, rounded to the nearest hundredth.
Answer:
0.35
the next one is d(v) = 2.15v^2 / 22.54
Step-by-step explanation:
i just did this assignment. also thanks to the answer above me :)
We have that the value of f, rounded to the nearest hundredth.
f_1=0.02
f_2=0.009
f_3=0.009
From the question we are told that
d(v)= \frac{2.15v^2}{64.4f}
Generally the equation for the f is mathematically given as
f= \frac{2.15v^2}{64.4*d(v)}
Therefore
For v=20 and f=38
f= \frac{2.15(20)^2}{64.4*(38)(20)}
f=0.02
For v=30 and f=86
f=\frac{2.15(30)^2}{64.4*(86)(30)}
f=0.01
For v=40 and f=153
f=\frac{2.15(40)^2}{64.4*(153)(40)}
f=0.009

pls help trigonometry is confusing to me :(
My first tip would be to label your triangles.
If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.
The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.
If you find the right angle and go across, that would be our hypotenuse.
//
In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.
[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]
[tex] \tan(43) = \frac{x}{40} [/tex]
if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.
Since x is on the numerator, we would have to multiply.
[tex]x = 40 \tan(43 ) [/tex]

solve (5w-8)/3 = 4w + 2[
Answer:
w = -2
Step-by-step explanation:
(5w - 8)/3 = 4w + 2
First, we will distribute the division problem on the left.
5w/3 - 8/3 = 4w + 2
Next, subtract 4w from both sides
5w/3 - 8/3 - 4w = 4w + 2 - 4w
We have to turn 4w on the left side into a fraction, but we have to make sure they are like fractions (meaning they have the same denominator).
5w/3 - 8/3 - 12w/3 = 2
5w/3 and -12w/3 are like terms (same variables) so we will subtract -12w/3 from 5w/3
-7w/3 - 8/3 = 2
Now, we will add 8/3 to both sides
-7w/3 - 8/3 + 8/3 = 2 + 8/3
to add 2 and 8/3 together, we need to make them like fractions
-7w/3 = 6/3 + 8/3
-7w/3 = 14/3
Now we get rid of the 3 by mutliplying 3 to both sides
3 * (-7w/3) = 3 * (14/3)
-7w = 14
No we have to divide -7 to both sides
-7w/-7 = 14/-7
w = -2

. Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?
This question is incomplete
Complete Question
A school held several evening activities last month—a music concert, a basketball game, a drama play, and literacy night. The music concert was attended by 250 people. How many people came to each of the other activities?
Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?
Answer:
350 people
Step-by-step explanation:
Percentage of people that attended a drama play =
Number of people that attended the drama play/Total number of people at the concert × 100
Attendance at the drama play was 140% of attendance at the concert.
The music concert was attended by 250 people
Let the number of people that came to the drama play = x
Hence:
140% = x/250 × 100
140/100 = x/250
Cross Multiply
140 × 250 = 100 × x
x = 140 × 250/100
x = 350 people
Therefore, the number of people that came to the drama play = 350 people
PLZZZ HELP!!! WILL MARK BRAINLIEST! Maggie wants to know if the number of words on a page in her science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Mean Median Mean Absolute Deviation
Science 49.7 41 8.4
Math 34.5 44 1.9
She claims that because the mean number of words on each page in the science book is greater than the mean number of words on each page in the math book, the science book has more words per page. Based on the data, is this a valid inference? (1 point)
Question 12 options:
1)
Yes, because there is a lot of variability in the science book data
2)
Yes, because the mean is larger in the science book
3)
No, because the mean is larger in the science book
4)
No, because there is a lot of variability in the science book data
Answer:
4) No, because there is a lot of variability in the science book dataStep-by-step explanation:
Mean absolute deviation is too large for the science book, therefore the mean is not a reliable data to consider.
Since we can't rely on the mean, Maggie's conclusion is not right.

Leigh-Anne invests £2500 for 4 years in a savings account.
She gets 3% per annum compound interest.
How much money does Leigh-Anne have at the end of 4 years.
Answer:
After 4 years, Leigh-Anne will have £ 2,813.77 in her account.
Step-by-step explanation:
Given that Leigh-Anne invests £ 2500 for 4 years in a savings account, and she gets 3% per annum compound interest, to determine how much money does Leigh-Anne have at the end of 4 years, the following calculation must be performed:
X = 2,500 x (1 + 0.03 / 1) ^ 4
X = (2,500 x 1,003) ^ 4
X = 2,813.77
Thus, after 4 years, Leigh-Anne will have £ 2,813.77 in her account.
