Use the graph of the function. Determine over what interval(s) the function is positive or negative.
Answers
Answer:
The function is positive
Step-by-step explanation:
As you can see, the line makes a U shape aiming for the positive side of the graph.
The function in which the function is positive is (- 2, -1] ∪ [1, 2) and negative is [-1 to 1].
We have a graph of a function f(x).
We have to determine over what interval the function is positive or negative.
Define Function.A function from a set X to a set Y is an assignment of an element of Y to each element of X. The set X is called the domain of the function and the set Y is called the codomain of the function. For example - shown below is a piecewise function -
[tex]f(x) = \left\{ \begin{array}{ll} x^2 \quad x > 0 \\ 0 \quad \text{else} \end{array} \right.[/tex]
According to the question, we have a graph.
It can be seen in graph that the function f(x) is '+' in ranges : - 2 to -1 and 1 to 2.
The interval in which f(x) is positive is → (- 2, -1] ∪ [1, 2).
In the interval of : -1 to 1, the function has a negative value.
The interval is → [-1 to 1]
Hence, the function in which the function is positive is (- 2, -1] ∪ [1, 2) and negative is [-1 to 1].

2x + 4y = 20
-6X - 4y = 24
Answers
Answer: (-2,3)
Step-by-step explanation:
-3x + 4y = 18
6x + 2y= -6 we have to eliminate one of the variables so you will have ot
2(-3x + 4y) = 18(2) multiply the first equation by 2.
-6x + 8y = 36
6x + 2y = -6 now we could eliminate the x terms by adding them and
0 + 10y= 30 remember that is a new equation.
y= 3
Now we know that the y solution is 3 so we will put it into one of the equations and solve for x.
-6x + 8(3)=36
-6x + 24
-24 -24
-6x = 12

can you write an equivalent fraction for 5/9 and 1/10 using the least common denominator?
Answers
Answer: Yes
Step-by-step explanation:
Rewriting input as fractions if necessary:
5/9, 1/10
For the denominators (9, 10) the least common multiple (LCM) is 90.
LCM(9, 10)
Therefore, the least common denominator (LCD) is 90.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
5/9 = 5/9 × 10/10 = 50/90
1/10 = 1/10 × 9/9 = 9/90
3/4 - 7/9 + 2/3

For every 6 inches of height, Lashacha has an arm span of about 6.17 inches. If Lashacha is 6 ft 5 in. tall, predict the width of her arm span.
Answers
Answer: 79.18 inch.
Step-by-step explanation:
Given: For every 6 inches of height, Lashacha has an arm span of about 6.17 inches.
i.e. for each inch of height she has an arm span of = [tex]\dfrac{6.17}{6}[/tex] inches
Height of Lashacha = 6 ft 5 in.
1 ft = 12 inches
Then, Height of Lashacha = [6(12)+ 5] = 77 in.
So for 77 inch height she has arm span of [tex]\dfrac{6.17}{6}\times77=79.18\text{ inch}[/tex]
Hence, the width of her arm span = 79.18 inch.

A round garden has a circumference of 15.7 feet. Calculate the area of
the garden
Answers
Answer:
The area of a circle with circumference 15.7 is 19.62
Step-by-step explanation:
If this helped May I have brainliest Im trying to rank up.
Have a great day!
The area of the garden is 19.64 feet²
The garden has the shape of a circle.
The area of a circle = πr²
Where:
π= pi = 22/7
r = radius
In order to determine the area of the garden, the radius has to be determined first. The radius would be determined from the circumference of the circle.
Circumference of the circle = 2πr
15.7 = 2 x (22/7) x r
r = 15.7 ÷ ( 2 x 22/7)
r = 2.50 feet
Area of the garden = (22/7) x (2.5²) = 19.64 feet²

The product of two rational numbers is a rational number.
What is a rational number?"A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator 'p' and a non-zero denominator 'q'."
Therefore, when we are multiplying two rational numbers, their product must be a rational number.
This is because, numerators of both rational numbers are integers and denominators of both the numbers are non-zero integers.
Hence, the product is a rational number.

The power that has a greater value than 340 and less than 345 is 343 which is 7³.
What is prime factorisation ?Prime factorisation of numbers is writing a given number in terms of prime divisors.
For example -: 36 = 6 × 6.But 6 is not a prime number.
∴ 36 = 6 × 6 = 2×3×2×3 = 2² × 3².
To obtain the power of a number which is greater than 340 and less than 345 we have prime factorise these given numbers and see which one them is a perfect square or a perfect cube.
If we prime factorise 343 which is = 7 × 7 × 7.
