Answer:
Slope =-3, y intercept =4
Step-by-step explanation:
y2-y1/x2-x1 = slope
4-(-2)/0-2=6/-2 or -3
y intercept is where line crosses y axis so it is 4.
Answer:
Slope: -3, y-intercept: 4
Explanation:
=> In order to find slope when a graph is given, the formula would be: [tex]\frac{rise}{run}[/tex](pronounced as "rise over run")
Rise = change in y-value = -3
Run = change in x-value = 1
Slope = [tex]\frac{rise}{run}[/tex] = [tex]\frac{-3}{1}[/tex] also could be written as -3
=> Now, to find the y-intercept, find a value on the graph where the line touches the y-axis, that's where x = 0, which would be your y-intercept;
Here the line touches the y-axis at "y = 4", this is also where x = 0;
therefore y-intercept = 4
Hope this helps!

An adult has a total of about 21.4 square feet (ft2) of skin. Use the fact that 1 m is approximately equal to 3.281 feet to convert this measurement to square meters (m2).
Answers
Answer:
1.99m²
Step-by-step explanation:
From the above question
1 ft = 3.281 m
1 ft² = (3.281 m)²
Converting 21.4 ft² to m²
1 ft² = (3.281 m)²
21.4 ft² = xm²
x m² = 21.4 ft²/ (3.281 m)²
x m² = 1.9879310292 m²
Approximately :
21.4 ft² = 1.99m²
The green parallelogram is a dilation of the black parallelogram. What is the scale factor of the dilation?
A) 1/3
B) 1/2
C) 2
D) 3
Answers
=============================================================
Explanation:
"The green parallelogram is a dilation of the black parallelogram"
This tells us that the preimage is the black parallelogram and the image is the green one.
In short, the mapping is [tex]\text{black} \to \text{green}[/tex]
The image is smaller than the preimage (green is smaller than black), indicating the scale factor is some value of k such that 0 < k < 1. We can rule out choices C and D because of this.
--------------------
Measuring along the top, we can see that the black parallelogram goes from x = -6 to x = 8. Check out the image shown below where I've marked your given diagram, adding on helpful lines to show this going on.
The number-line distance from x = -6 to x = 8 is 14 units, so the top side of the black parallelogram is 14 units long.
The corresponding top side of the green parallelogram is 7 units long (because it spans from x = -3 and x = 4; as shown in blue in the figure below).
Divide the image length over its corresponding preimage length to get the scale factor.
scale factor = (image length)/(preimage length)
scale factor = 7/14
scale factor = 1/2
which points to choice B as our final answer.

In what ratio must 40m3 be decreased to become 24m3?
Answers
Answer:
40m3 must be decreased by 40% to become 24m3.
Step-by-step explanation:
To determine in what ratio must 40m3 be decreased to become 24m3, the following calculation must be performed:
40 = 100
24 = X
24 x 100/40 = X
2400/40 = X
60 = X
100 - 60 = 40
Therefore, 40m3 must be decreased by 40% to become 24m3.
Ricky and Lucy are 40 miles apart on bicycles heading towards each other on the same road. Ricky bicycles at 8 mph and Lucy rides at 6 mph. In how many hours will they meet?
Answers
Answer:
2.86 hours
Step-by-step explanation:
Ricky and Lucy are 40 miles apart on bicycles heading towards each other on the same road. Ricky bicycles at 8 mph and Lucy rides at 6 mph. In how many hours will they meet?
Speed = Distance/time
Distance = Speed × time
t = ?
Hence,
8mph ×t + 6 mph × t = 40 miles
8t + 6 t = 40 miles
14t = 40 miles
t = 40/14
t = 2.86 hours
They will meet in 2.86 hours

time in seconds.
*Find the maximum height a launched item
could reach. (Round to two decimal places).
*After how many seconds will an item hit the
water after being launched? (Round to nearest
whole number).
Please someone help me
Answers
Answer:
i) 524.25feet
ii) 11secs
Step-by-step explanation:
1) Given the height of the rocket modelled by the equation
h = -16t² + 180t + 18 where
t is in seconds
At the maximum height, the velocity of the object is zero.
v(t) = dh/dt = 0
dt/dt = -32t + 180
0 = -32t + 180
32t = 180
t = 180/32
t = 5.625secs
Get the maximum height
h = -16t² + 180t + 18
h = -16(5.625)² + 180(5.625) + 18
h = -16(31.640625)+ 180(5.625) + 18
h = -506.25+1,012.5+18
h = 524.25feet
Hence the maximum height a launched item could reach is 524.25feet
ii) The item will hit the water at h = 0
Substitute inti the expression
h = -16t² + 180t + 18
0 = -16t² + 180t + 18
16t² - 180t - 18 = 0
Divide through by 2
8t² - 90t - 9 = 0
t = 90±√90²-4(8)(-9)/2(8)
t = 90±√8100+288/16
t = 90±√8,388/16
t = 90±91.586/16
t = 90+91.586/16
t = 181.586/16
t = 11.35sec
Hence the item hit the water after 11secs (to nearest whole number)

Tiara, a quality assurance inspector at a chocolate factory, checks for product quality using a random sample of 18 pieces of chocolate from a batch of 60, wity 17 white chocolate and 43 dark chocolates. Let p be the proportion of white chocolates in the sample. Part A: Is the 10% condition met in thjs case? Justify your answer. Part B: Is the Normal condition met in this case? Justify your answer.
Answers
Answer:
Part A
The 10% rule is not met
Part B
The normal condition is not met
Step-by-step explanation:
The given data of the pieces of chocolate are;
The number of chocolates in the sample, n = 18
The number of white chocolate in the batch = 17
The number of dark chocolates in the batch = 43
Given that [tex]\hat p[/tex] is the proportion of white chocolates in the sample, we have;
The proportion of white chocolates in the batch, p = 17/60 = 0.28[tex]\overline 3[/tex]
Part A
The 10% condition states that the size of the sample should be less than or equal to 10% of the population because taking samples without replacing them does not result in independent Bernoulli trials
The given sample size, n = 18, which is 18/60×100 = 30% > 10% of the batch, therefore, the 10% rule is not met in the present situation
Part B
The normal approximation can be assumed when we have;
n·p > 10 and n·p·(1 - p) > 10
By plugging in the values for 'n' and 'p', we have;
p = 0.28[tex]\overline 3[/tex] = 17/60
n·p = 18 × 17/60 = 5.1 < 10
n·p·(1 - p) = 18 × 17/60 × (1 - 17/60) = 3.655 < 10
Therefore the normal condition is not met.
