Plot (−134,412) on the coordinate plane.
We are given coordinate (-1 3/4, 4 1/2).
(-1 3/4, 4 1/2) represents x-coordinate -1 3/4.
And y-coordinate 4 1/2.
First we need to go -1 and three fourth between -1 and -2.
And then for 4 1/2, we need to got 4 above on y-axis and then a half between 4 and 5.
We would draw the coordinate of intersection of vertical line of point -1 3/4 and horizontal line at 4 1/2.
The shown green point on the graph is the coordinate (-1 3/4, 4 1/2).Answer:

What is the value of n?
Enter your answer in the box.
n = cm
Answer:
n = 14 cm
Step-by-step explanation:
We are required to find the find the value of n.
Since, we have the lines are intersecting in the circle.
So, using the 'Intersecting Chord Theorem', which states that the product of the line segment formed by the intersecting lines are equal.
[tex]4\times n= 8\times 7[/tex]
i.e. [tex]4n=56[/tex]
i.e. n = [tex]\frac{56}{4}[/tex]
i.e. n = 14
Hence, the value of n is 14 cm.

Quadrilateral ABCD is inscribed in circle O.
What is m∠B?
m∠A + m∠B = 180°
2x - 7 + 2x + 3 = 180
4x - 4 = 180
4x = 184
x = 46
m∠B = 2x + 3
m∠B = 2(46) + 3
m∠B = 92 + 3
m∠B = 95°

In the United States the speed limit signs are in miles per hour. Unfortunately, your speedometer only reads in km/hour. How fast are you allowed to go if the speed sign says 70 mph (rounded to the nearest hundredth)
Answer:
The speed limit will be 112.65 kph.
Step-by-step explanation:
In order to find how fast one can go when speed sign says 70mph and the speedometer reads in km per hour we convert mph to kmph.
The conversion unit is 1mph= 1.609344kph
So 70mph = 70x1.609344=112.6541kph
Or 70mph=112.65 kph
One can travel at 112.65 kph.

Describe the relationship of input and output values for composite functions.
Identify the factors of 9x2 + 30x + 25.
A) (3x − 5)(3x − 5)
B) (3x + 5)(3x + 5)
C) (9x + 5)(x + 5)
D) (9x − 5)(x − 5)
Answer:
B is correct
Step-by-step explanation:
The signs of the coefficients tell you the binomial factors must have both signs positive (selections B and C only). Selection B produces an x-term that is 15x+15x=30x (as we want); selection C produces an x-term that is 45x+5x=50x (not what we want).

Lamar has a summer job. He gets paid $7.25 an hour and a $150 bonus at the end of summer. The total Lamar earns can be modeled by the equation f(h) = 7.25h + 150, where h is the number of hours he works. In what form is the equation?
Final answer:
The equation representing Lamar's summer job earnings is in linear form with a constant rate of change represented by 7.25 and a vertical intercept of 150, which is his end-of-summer bonus.
Explanation:
The equation provided, f(h) = 7.25h + 150, is in linear form. This type of equation is used to model a relationship where the dependent variable, f(h), which represents Lamar's earnings, changes at a constant rate with respect to the independent variable, h, which represents the number of hours worked. The number 7.25 represents Lamar's hourly wage, while the 150 represents a fixed bonus amount he receives at the end of the summer, making it the constant term or vertical intercept when graphed on a coordinate plane.
Suppose you roll a special 49-sided die. what is the probability that the number rolled is a "1" or a "2"?
Final answer:
The probability of rolling a "1" or a "2" on a 49-sided die is found by adding the separate probabilities of each event, resulting in 2/49 or approximately 0.04082.
Explanation:
In probability, when you want to find the chance of one event or another occurring, you add the probabilities of each event if they cannot happen at the same time. Given a special 49-sided die, each outcome is equally likely, and every roll is an independent event. Therefore, the probability of rolling a "1" is 1 out of 49, and the probability of rolling a "2" is also 1 out of 49. To find the combined probability of rolling either a "1" or a "2", you simply add these two probabilities together.
The probability of rolling a "1" is 1/49, and the probability of rolling a "2" is 1/49. So, the combined probability (P) is:
P("1" or "2") = P("1") + P("2") = 1/49 + 1/49 = 2/49 or approximately 0.04082.

A motorcycle cost $12,000 when it was purchased. The value of a motorcycle decreases by 6% each year. Find the rate of decay each month and select the correct answer below.
−0.005143%
−0.5143%
−0.005%
−0.5%
The rate of decay each month is given by 0.5143% and this can be determined by forming the expression from the given data.
Given :
A motorcycle cost $12,000 when it was purchased.The value of a motorcycle decreases by 6% each year.There are 12 months in a year then the value motorcycle retains every year is:
[tex]x^{12}=0.94[/tex]
Now, take the log on both sides in the above equation.
[tex]\rm logx^{12}=log(0.94)[/tex]
12 log x = log(0.94)
Now, divide log(0.94) by 12 in the above expression.
[tex]\rm log x = \dfrac{log(0.94)}{12}[/tex]
log x = -0.00223934553
[tex]x = 10^{-0.00223934553}[/tex]
x = 0.994856987
Now, to determine the rate of decay:
= (1 - x)100
= (1 - 0.994856987)100
= (0.005143)100
= 0.5143%
Therefore, the correct option is B).
