Jada and lin are comparing inches and feet. Jada says that the constant of proportionality is 12. Lin says it is 1/12
Answer:
Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.
Step-by-step explanation:
Let
Inches = x
Feet = y
Constant of proportionality = k
ratio of feet to inches
x = ky
1 feet = 12 inches
12 = k * 1
k = 12/1
k = 12
Ratio of inches to feet.
y = kx
1 = k * 12
k = 1/12
Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.

share £242 in the ratio 1:2:3:5
Answer:
£22 : £44 : £66 : £110
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 + 5 = 11 parts
Divide the amount by 11 to find the value of 1 part of the ratio
£242 ÷ 11 = £22 ← value of 1 part of the ratio, then
2 parts = 2 × £22 = £44
3 parts = 3 × £22 = £66
5 parts = 5 × £22 = £110
Then £242 in the ratio 1 : 2 : 3 : 5 is £22 : £44 : £66 : £110

a store owner sells a mix that is 45% cashew nuts how many pounds of cashews should be add to 36 lb to make it 60% cashews
Answer:
13.5 lbs
Step-by-step explanation:
The number of pounds to be added with 36 lb to make cashews nut 60% is 12 pounds.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
45% cashew nuts = 36 lb
Multiply 60/45 on both sides.
60% = 60/45 x 36 lb
60% = 48 lb
The number of pounds to be added.
= 48 - 36
= 12 lb
Thus,
12 pounds of cashew should be added to 36 lb to make it 60% cashews.

m = 11/2
n = (1 + 4)/2
n = 5/2
O = (11/2, 5/2)
Now,
O is the midpoint of AC.
m = (x + 0)/2

A polynomial function has a root of –7 with multiplicity 2, a root of –1 with multiplicity 1, a root of 2 with multiplicity 4, and a root of 4 with multiplicity 1. If the function has a positive leading coefficient and is of even degree, which statement about the graph is true?
A. The graph of the function is positive on (2, 4).
B. The graph of the function is negative on (4,infinity).
C. The graph of the function is positive on (-infinity, –7).
D. The graph of the function is negative on (–7, –1).
Answer:
Step-by-step explanation:
c
The correct statement about the graph will be;
''The graph of the function is positive on (-∞, –7).''
Option C is true.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
A polynomial function has a root of –7 with multiplicity 2, a root of –1 with multiplicity 1, root of 2 with multiplicity 4, and a root of 4 with multiplicity 1.
And, The function has a positive leading coefficient and is of even degree.
Now,
A polynomial function has a root of –7 with multiplicity 2.
Then, we get;
(x + 7)²
And, a root of –1 with multiplicity 1.
Then, we get;
(x + 1)¹ = (x - 1)
And, a root of 2 with multiplicity 4.
Then, we get;
(x - 2)⁴
And, a root of 4 with multiplicity 1.
Then, we get;
(x - 4)¹ = (x - 4)
So, The polynomial is;
P(x) = a (x + 7)² (x + 1) (x - 2)⁴ (x - 4)
After rearranged we get;
P (x) = a (x + 7)²(x - 2)⁴(x + 1) (x - 4)
Now, We check all options as;
For option A; The graph of the function is positive on (2, 4).
Substitute (x, y) = (2, 4) in the polynomial;
P(3) = a (3 + 7)²(3 - 2)⁴(3 + 1) (3 - 4)
= a × 100 × 1 × 4 × -1
= -400a
Thus, The graph of the function is negative on (2, 4).
So, Option A is false.
For option B; The graph of the function is negative on (4,infinity).
Substitute x = 6;
P(6) = a (6 + 7)²(6 - 2)⁴(6 + 1) (6 - 4)
= a × 169 × 16 × 7 × 2
= 37,856a
Thus, The graph of the function is positive on (4,infinity).
So, Option B is false.
For option C; The graph of the function is positive on (-infinity, –7).
Substitute x = -8;
P(-8) = a (-8 + 7)²(-8 - 2)⁴(- 8 + 1) (-8 - 4)
= a × 1 × 10,000 × -7 × -12
= 840,000a
Thus, The graph of the function is positive on (-infinity, –7).
Option C is true.
Therefore, The correct statement about the graph will be;
''The graph of the function is positive on (-∞, –7).''
Option C is true.
