Answer:

Step-by-step explanation:

Given quadratic function is,

f(x) = -x² - x + 1

Range of the function has been defined as (-∞, [tex]\frac{5}{4}[/tex] ]

Domain of the function is a set of all real numbers.

From the graph of this function,

At x = -3 and x = 2, value of y = -5

But for one to one functions, every x value should map to a different value of y.

Therefore, function is not one to one.

Since, every value of domain (x-value) maps the range (y-value) in the given range (-∞, [tex]\frac{5}{4}[/tex] ], function will be defined as onto.

Therefore, this function is ONTO, but NOT ONE TO ONE.

Answer:

823/30

or 27 13/30

decimal: 27.43

Step-by-step explanation:

(25+7)+ (1/6 + 2/5)

32+ (5/30 + 12/30)

32+ 17/30

= 32 17/30

60- 32 17/30

= 1800/30 - 977/30

= 823/30

= 27 13/30

Option B) The cat weighs 4 kilograms when it is 7 months old.  is correct answer.

w gives weight of cat, in kgs, when it is m months old.

What does w(7) = 4 represents.

It is already given that w gives weight in kilograms.

It outputs weight when we tell the age in months, thus, this is what we treat as input.

w(7) means weight when cat is 7 months old.

and w(7) = 4 represents that the cat weighs 4 kilogram when the age of cat is 7 months.

Thus, Option B) The cat weighs 4 kilograms when it is 7 months old.  is correct answer.

Step-by-step explanation:

First know that any value raise to power zero is 1 and also according to the inverse law;

a⁻ⁿ = 1/aⁿ

Given the following

a) (-123)⁰ = 1 ()Note that any value raise to zero is 1

b) 43⁻⁵ = 1/43⁵

1/43⁵ = 1/147,008,443

c) 1/15⁻⁶ = 1/(1/15⁶)

1/(1/15⁶) = 1*15⁶/1

1/(1/15⁶) = 15⁶

d) -(1353348)⁰

= -1 (anything raise to zero is 1)

e) 13⁻⁴ = 1/13⁴

= 1/28,561

Answer:

D) y > x – 2 and y < x + 1

Step-by-step explanation:

- Graph each system of linear inequalities.

- Examine each graphed system of linear inequalities

- Match the system of linear inequalities that looks the same as the graph shown

Remember:

> and < are dashed lines

≥ and ≤ are solid lines

if y is ≥ or > , then the shaded region is above the graphed line

if y is ≤ or <, then the shaded region is below the graphed line

m = slope

b = y intercept

change the inequality sign into an equal sign to check the y intercept.

use the equation y = mx + b to check each one

Answer:

The median is: 2

Step-by-step explanation:

First put the numbers in ascending order:

-19, -13, -4, 1, 2, 5, 9, 14, 15

The value in the middle will be the median.

Answer:

2

Step-by-step explanation:

for finding the median you can either arrange the set of numbers in increasing order or decreasing order

then you come the numbers in group of food from the beginning and end then the last single number you get to be your Median number

In increasing order

-19,-13,-4,1,2,5,9,14,15

Answer:

The difference in area is 672 cm^2

Step-by-step explanation:

Firstly, let us get the diameter of the circle

The length of the wire is the measure of the circle’s circumference

mathematically;

C = pi * d

176 = 22/7 * d

22d = 7 * 176

d = (7 * 176)/22

d = 56 cm

So, the area of the circle will be;

pi * d^2/4

= 22/7 * 56 * 56 * 1/4

= 2464 cm^2

Also, the length of the circumference is same as the perimeter of the rectangle

From the perimeter of the rectangle, we can get the width and use that to calculate the area of the rectangle

The formula for the perimeter of the rectangle is;

2(l + b)

2(56 + b) = 176

56 + b = 88

b = 88-56

b = 32 cm

So, the area of the rectangle will be;

32 * 56 = 1792 cm^2

The difference between the two areas will be;

2464-1792 = 672 cm^2

Answer:

D. (-1, -2) and (3, 6)

Step-by-step explanation:

y = 2x

y = x² - 3

2x = x² - 3

(x + 1)(x - 3) = 0

x = -1 or x = 3

y = -2 or y = 6
