The equation of the line passing from the given points is y = -5x/2-1
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, a line is passing through two points (-2, 4) and (0 -1)
We know that, the equation of a line passing through two points is given by,
y-y₁ = (y₂-y₁/x₂-x₁)(x-x₁)
Therefore,
y-4 = (-1-4)/(0+2)(x+2)
y-4 = -5/2(x+2)
y = -5x/2-5+4
y = -5x/2-1
Hence, The equation of the line passing from the given points is y = -5x/2-1

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of grams and a standard deviation of grams while babies born after a gestation period of 40 weeks have a mean weight of grams and a standard deviation of grams. If a -week gestation period baby weighs grams and a -week gestation period baby weighs grams, find the corresponding z-scores. Which baby weighs relative to the gestation period?
Complete question :
Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 410 grams. If a 32 -week gestation period baby weighs 3300 grams and a 40 -week gestation period baby weighs 3600 grams, find the correspondingz-scores. Which baby weighs more relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively more?
Answer:
32 - 35 weeks = 0.56
40 weeks : 1.22
40 weeks babies weigh more
Step-by-step explanation:
Given that :
32 - 35 weeks babies :
Mean (m) = 2800
Standard deviation (s) = 900
Weight (x) = 3300
40 weeks babies :
Mean (m) = 3100
Standard deviation (s) = 410
Weight (x) = 3600
Obtain the standardized score for both categories :
Zscore = (x - m) / s
32 - 35 weeks :
Zscore = (3300 - 2800) / 900
Zscore = 0.555555 = 0.56
40 weeks :
Zscore = (3600 - 3100) / 410
Zscore = 1.2195121 = 1.22
Zscore for 40 weeks is higher than 32-35 weeks.
Hence, 40 weeks babies weigh more.
for the function g (x) shown graphed below, over which of the following intervals is g (x) > 0
Answer:
g(-1) is lesser than 0 while h(-1) is -3(-1) + 8 = 11 so g(-1) is lesser than h(-1)
g(1) is 5 while h(1) is -3(1) + 8 = 5 so g(1) is equal to h(1)
Step-by-step explanation:
The function g(x) is greater than zero when the value of x lies in between -3 and 5 and this can be determined by using the given graph.
Given :
The graph of the function g(x) is given.
The following steps can be used in order to determine the interval for g(x):
Step 1 - The value of g(x) means the value of y.
Step 2 - The value of g(x) is positive when the graph of g(x) is in the first or in the second quadrant.
Step 3 - So, according to the graph function g(x) is positive when the value of x is in between -3 and 5.
Therefore, the correct option is 3).

A rectangle has a width of 3 units and a length of 4 units. Nancy needs to increase both the length and the width of the rectangle by 2 units.
Image_8672
Which statement describes how the area of the rectangle will change?
Step-by-step explanation:
The length of a rectangle, l = 3 units
The breadth of a rectangle, b = 4 units
Nancy needs to increase both the length and the width of the rectangle by 2 units.
The area of a rectangle is given by
A = length(l) × breadth(b)
Here,
A = 3 × 4
= 12 unit²
If both length and width of the rectangle increase by 2 units,
New length = (4+2) = 6 units
New width = (3+2) = 5 units
New area = 6 × 5 = 30 unit²
Hence, new area becomes 30 unit².

In the figure below, if the radius of circle o
is 10, what is the length of diagonal AC of
rectangle OABC?
Answer:
The length of AC is 10 units
Step-by-step explanation:
In the given circle O
∵ AOCB is a rectangle
∵ OB and AC are the diagonals of the rectangle AOCB
∵ Diagonals of the rectangle are equal in lengths
→ That means OB and AC are equal in lengths
∴ OB = AC
∵ O is the center of the circle
∵ B is a point on the circle
∴ OB is a radius of the circle O
∵ The radius of the circle is 10 units
∴ OB = 10 units
∵ OB = AC
∴ AC = 10 units
∴ The length of AC is 10 units

Factor the expression using the GCF.
42 – 12 =
The factors of the expression 42 - 12 are 2(21 - 6), 3(14 - 4), 6(7 - 2).
What are GCF and distributive property?The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.
We also know that distributive property states a(b + c) = ab + ac.
Given, We have to factor 42 - 12.
Now, Factors of 12 are 1, 2, 3, 4, 6 and 12.
Factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.
Common factors of 12 and 42 are 2, 3 and 6.
So, 42 - 12.
= 2(21 - 6).

The factored form of the expression 42 - 12 using the GCF is 6(7 - 2).
To factor the expression 42 - 12 using the greatest common factor (GCF), we need to find the largest number that divides both 42 and 12.
First, let's find the prime factorization of both numbers:
42 = 2 x 3 x 7
12 = 2 x 2 x 3
Now, let's find the common factors:
The common factors are 2 and 3.
Next, let's determine the GCF by multiplying the common factors:
GCF = 2 x 3 = 6
Finally, we can factor out the GCF from the expression:
42 - 12 = 6 x (7 - 2)
Therefore, the factored form of the expression 42 - 12 using the GCF is 6(7 - 2).

A=(2,3)
B=(6,-2)
C=(10,-1)
D=(11,6)
Two transformations will be applied:
T(x,y)->(x+12,y-8). It means: add 12 to x, subtract 8 to y
T(x,y)->(x-6,y+5). It means: subtract 6 to x, add 5 to y

A'=(2+12,3-8)=(14,-5). Second translation:
A''(14-6,-5+5)=(8,0)
Now for point B. First translation:
B'=(6+12,-2-8)=(18,-10). Second translation:
B''(18-6,-10+5)=(12,-5)

Answer:
y = -1/4x^2 -3/2x +3/4
Step-by-step explanation:
You know that vertex form is ...
y = (1/(4p))(x -h)^2 +k
for a focus-vertex distance of p and a vertex of (h, k).
Here, the focus-vertex distance is 2-3 = -1 (difference of y-coordinates), and the vertex is (h, k) = (-3, 3). This means the vertex form equation is ...
y = -1/4(x +3)^2 +3
Expanding the square gives ...
y = -1/4(x^2 +6x +9) +3
y = -1/4x^2 -3/2x +3/4
