Given the following linear function sketch the graph of the function and find the domain and range. f( x ) = 2/7 x− 2
Answers
Answer:
Domain: All Real Numbers Range: All Real Numbers
Step-by-step explanation:
The domain and range is going to be infinite. The linear function will be using the x and y- axis in order to continue being a function. The y-intercept will be -2 on the y-axis. I recommend using the rise-over-run method for your slope value. from the point (0, -2) on the y-axis. Go up two on the y-axis, and right 7 on the x-axis.

Fill the empty slots by dragging tiles from the left to show the next step for solving the equation. Solve the two-step equation. -9x + 0.4 = 4
Which operation must be performed to move all the constants to the right side of the equation?
Answers
In order to move a the constant terms to the right hand side, we need to subtract 0.4 from both sides of the equation.
What are the constant terms?In an equation, the constant terms are those terms that do not have any alphabet attached to them. In this case, 4 and 0.4 are constant terms.
In order to move a the constant terms to the right hand side, we need to subtract 0.4 from both sides of the equation thus;
-9x + 0.4 - 0.4 = 4 - 0.4

What is the length of the hypotenuse of right ΔDEF shown? A) √5041 B) √2545 C) √497 D) √1063
Answers
The length of the hypotenuse of right triangle ΔDEF is 50.44 units
How to find hypotenuse of a right triangle?The hypotenuse side can be found using Pythagoras theorem,
Therefore,
c² = a² + b²
where
c = hypotenusea and b are the other legs.Therefore,
x² = 39² + 32²
x² = 1521 + 1024
x = √2545
x = 50.4479930225

What is the perimeter of a figure?The perimeter of a figure is given by the total length of it's boundary.
In this problem, we have that:
The bottom boundary has length of 10 units.The two lateral boundaries have lengths of 7 units.There are two top boundaries, which are the hypotenuses of a right triangle with legs 3 and 5, hence:[tex]t = \sqrt{3^2 + 5^2} = 5.83[/tex]
Hence the perimeter of the figure is:
P = 10 + 2 x 7 + 2 x 5.83 = 35.66.
Rounding, it is of about 36 ft, hence option A is correct.

In a large population, 76% of the households have cable tv. A simple random sample of 225 households is to be contacted and the sample proportion computed. What is the mean and standard deviation of the sampling distribution of the sample proportions
Answers
0.017559
It is given that:
Probability of Households Having cable TV, p₀ = 76% = 0.76
Therefore,
The probability that the Households not having cable TV = 1 - 0.76 = 0.24
Sample size, n = 225 households
sample proportions is less than 82% i.e p = 0.82
Now,
The standard error, SE = [tex]\sqrt{} \frac{0.76(1-0.76)}{225}[/tex]
= 0.02847
Z = [tex]\frac{0.82-0.76}{0.02847}[/tex]
Z = 2.107
therefore, P(sample porportions < 0.82) = P(Z < 2.107)
now from the p value from the Z table we get P(sample porportions < 0.82) = 0.017559

Calculate the area of triangle OPQ.
Answers
Thus, we need information about the sides OQ and PQ to solve the triangle and find the area. The information given is not enough to determine the area of the triangle.
Is this triangle solvable?
In this question we must analyze if the area of the triangle OPQ can be found by all information given. By the law of the cosines we understand that lengths of two sides and the measure of an angle should be known to construct a triangle and by the law of the sines we understand that either two angles and a side or two sides and an angle must be known.

A tire on a car has an outside diameter of 36.30 in. Through what angle (in radians) does the tire turn while traveling 1 mile?
Answers
Answer: 3491.91 radians
Step-by-step explanation:
The total distance in inches traveled by car = 63,360 inches (1 mile)
Total Revolution made by tire through traveling =
[tex]=\frac{63360}{\pi *36.30}[/tex]
We know 1 revolution angle made by tire = 2π radian (360 degrees/1 revolution of unit circle)
In [tex]\frac{63360}{\pi *36.30}[/tex] ,
the revolution angle made by the tire =

Properties of an Equilateral Triangle
Three sides of equal lengthAll interior angles are 60°Given:
ΔABC is an equilateral triangleVertex A is at (0, √3)Drawing an altitude from vertex A divides the triangle into two 30-60-90 triangles.
A 30-60-90 triangle is special right-angled triangle where:
Angles are in the ratio 1 : 2 : 3Sides are in the ratio 1 : √3 : 2Therefore, the formula for the sides is: b : b√3 : 2b, where:
b = shortest side opposite the 30° angleb√3 = side opposite the 60° angle2b = longest side (hypotenuse) is opposite the right angleAs Vertex A has the co-ordinates (0, √3), the side opposite the 60° angle is √3 units.
Using the ratios to find b (shortest side length):
b√3 = √3 ⇒ b = 1

Pauley graphs the change in temperature of a glass of hot tea over time. he sees that the function appears to decrease quickly at first, then decrease more slowly as time passes. which best describes this function?
Answers
Non-linear graph best describes this function.
Why nonlinear?
As described in the question, Pauley graphs the change in temperature of a glass of hot tea over time. He sees that the function appears to decrease quickly at first, then decrease more slowly as time passes. It is linear because the graph decreases over time. It is linear because there is both an independent and a dependent variable but it doesn't satisfies one condition of being linear. Thus, It's Nonlinear because linear functions are increasing functions. It is nonlinear because linear functions increase or decrease at the same rate.
