4. Which of the following values of x is not in the domain of f (x) = log; (10-2x)?
Answers
Answer:
its choice 3) 5
Step-by-step explanation:
We want to see which of the given values of x is not in the domain of f(x) = log(10 - 2x).
The correct option is (3); x = 5.
The domain is defined as the possible inputs of a given function f(x), in this particular case, we have:
f(x) = log(10 - 2x).
Remember that the logarithmic function is only defined for positive arguments, so the values of x that are NOT in the domain of f(x), are these x values such that:
10 - 2x ≤ 0
Solving it for x we have:
10 ≤ 2x
10/2 ≤ x
5 ≤ x
So any value of x equal to or larger than 5 is not in the domain of the given functions, and of the shown options, the only one that is equal or larger than 5 is x = 5, the third option.
So the correct option is the option (3).

Find the missing length.
Answers
Answer:
Triangle 1 - 4
Triangle 2 - 10
Step-by-step explanation:
To find the missing side lengths of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem states that: a² + b² = c². In this equation, a and b are legs, and c is the hypotenuse.
Using this to solve triangle 1, you get the equation: a² + 3² = 5² or a² + 9 = 25. To solve for a², you subtract 9 from both sides to get a² = 16. To solve for a, find the square root of 16, which is 4.
Using the Pythagorean Theorem to solve for triangle 2, you get the equation: 6² + 8² = c² or 36 + 64 = c². Add 36 + 64 to get 100 = c². Find the square root of 100 to solve for c. The square root is 10.

Use the table below to determine whether f(x) could represent a linear function. If it could write f(x) in the form f(x) = mx +b.
Answers
Answer:
5x-3
Step-by-step explanation:
This is linear because the numbers are changing at a constant rate (of 5)
We can also see that when x=0 y= -3 which means that in our equation
y=mx+b
-3 =b
I said prior that the rate of change is 5 which means that our slope is 5
which means that our equation looks like

Answers
Bob's linear speed is higher than Jack's because the radius of the circle
around which Bob rotates is larger.
Responses:
Jack's linear speed is approximately 377 feet per minuteBob's linear speed is approximately 527.8 feet per minuteWhat is the relationship between linear speed and angular speed?Given:
The rotational speed of the merry go round = 6 revolution per minute
Jack's distance from the center = 10 feet
Bob's distance from the center = 14 feet
The angular speed, ω, of the merry-go-round is found as follows;
[tex]\omega = \mathbf{\dfrac{6 \times 2 \cdot \pi}{1 \ minute}} = 12 \cdot \pi \ rad/minute[/tex]Linear speed = ω × rWhich gives;
Jack's linear speed = 12·π rad/min × 10 feet ≈ 377 feet per minuteBob's linear speed = 12·π rad/min × 14 feet ≈ 527.8 feet per minuteLearn more about angular speed and linear speed here:
