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.

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.

Answer:

Graph below

Step-by-step explanation:

Graph of a Function

We are given the function

y = f(x) = -4/3x + 8

Since this is the equation of a line, we only need two points to draw the graph, but we'll calculate some points more.

Select values for x={-3, 0, 3, 6, 9}

For x=-3:

y = -4/3(-3) + 8 = 4 + 8 = 12

Point (-3,12)

For x=0:

y = -4/3(0) + 8 = 0 + 8 = 8

Point (0,8)

For x=3:

y = -4/3(3) + 8 = -4 + 8 = 4

Point (3,4)

For x=6:

y = -4/3(6) + 8 = -8 + 8 = 0

Point (6,0)

For x=9:

y = -4/3(9) + 8 = -12 + 8 = -4

Point (9,-4)

Now plot the points in a rectangular grid and join them. The graph is shown below.

Step-by-step explanation:

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

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.

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.

Answer:

16 m  × 11 m

Step-by-step explanation:

The dimension of the gym is 20 m x 15 m. An outbound of 2m width is to be cut out from the gym to form the basketball court.

The original length of gym = 20 m and original width of gym = 15 m

2 m would be cut at both sides of the gym length for the outbound. Also 2 m would be cut at both sides of the gym width for the outbound. Therefore:

Length of basketball court = 20 m - (2 * 2m) = 20 m - 4 m = 16 m

Width of basketball court = 15 m - (2 * 2m) = 15 m - 4 m = 11 m

Therefore the dimensions of the basketball court is:

16 m × 11 m
