What is the distance between points A and B on the coordinate plane?
a ) 12
b) 10
c) 14.5
d) 100
Answers
Answer:
Step-by-step explanation:
use pythagorean theorem a^2 + b^2 = c^2
a = 6, b = 8
6^2 + 8^2 = c^2
100 = c^2
c = -10
since it cant really be negative, the distance becomes 10.

Which function is equivalent to g(x)= x2 +11x-60?
Answers
g(x) = x^2 + 11x - 60
(a=1, b=11, c=-60)
To solve this quadratic equation we need to find the discriminant:
discriminant= b^2 - 4ac
= (11)^2 - 4(1)(-60)
=121 - (-240) = 121+240 =361
(if discriminant<0 then equation has no real root
if discriminant=0 then equation has 1 real root
if discriminant>0 then equation has 2 real roots)
Here we have discriminant=361>0 so we have 2 real roots:
x1=(-b-redical discriminant) / 2a
and x2=(-b+redical discriminant) / 2a
x1= (-11-redical(361)) / 2(1)
=-15
x2= (-11+redical(361)) / 2(1)
=4
So we get the two roots x= -15 and x= 4
To write the quation in factorized form:
x= -15 means that x+15=0
x= 4 means that x-4=0
Therefore g(x)= (x+15)(x-4)
D is the correct answer

Find the area of the shaded region. Round to the nearest hundredth where necessary. Hint: Could you find the radius?
Answers
Answer:
13.72 cm²
Step-by-step explanation:
The formula to find the area of a shaded region: Area of the bigger shape - area of the smaller shape.
The formula to find the area of a square: [tex]a^{2}[/tex], where [tex]a[/tex] is the side.
The formula to find the area of a circle: [tex]\pi r^{2}[/tex], where [tex]\pi[/tex] is 3.14 or [tex]\frac{22}{7}[/tex] or 3.142 or similar, [tex]r[/tex] is the radius (diameter ÷ 2).
1) Find the area of the circle using the formula. The radius is 4 because the diameter is 8 (8 ÷ 2 = 4).
= [tex]\frac{22}{7}*4^{2}[/tex]
= [tex]\frac{22}{7}*16[/tex]
= 50.285
2) Find the area of the square using the formula.
= [tex]8^{2}[/tex]
= 64
3) Apply: area of the bigger shape - area of the smaller shape.
= 64 - 50.285
= 13.715
4) Round it off to the nearest hundredth.
= 13.72

60 point help What are domain restrictions of rational functions? What do domain restrictions mean for the graph of a rational function?
Answers
Answer:
1. The use of a domain for a function that is smaller than the function's domain of definition. Note: Restricted domains are commonly used to specify a one-to-one section of a function.
2. Domain restrictions can be calculated by finding singularities, which are the x -values for which the denominator Q(x) is zero.
Answer:
by setting the denominator equal to zero and solving. The x -values at which the denominator equals zero are called singularities and are not in the domain of the function.

Determine whether each statement correctly describes the likelihood of an event based on the given number cube. Select True or
False for each statement.
True or False
Answers
The statement that correctly descrives the likelilhood of an event based on the given numbered cube is: Option A: It is likely that a number less than 6 is occured.
How to decide the likelihood of an event?Suppose that for a considered sample space, we consider an event E
Then, E is likely to occur if:
[tex]P(E) \geq P(E')[/tex]
where [tex]E_i '[/tex] is complementary event of E (ie, E' occurs whenever E doesn't occur and vice versa)
If so, then we say that E is likely to occur as the outcome of the considered random experiment, else unlikely.
Since we have:
[tex]P(E) = 1- P(E')[/tex] due to E and E' being complement of each other, therefore, we get:
[tex]P(E) \geq 1 - P(E)\\P(E) \geq 0.5[/tex]
Thus, event E is said to be likely if its probability is greater or equal to 0.5, else not.
It is given that the cube is 6 faced (assuming all equally likely), numbered from 1 to 6.
Evaluating likelihood of each event:
It is likely that a number less than 6 is obtained on the number cube.P(Getting a number < 6 on that cube) = [tex]\dfrac{5}{6}[/tex] (since a number out of 6 numbers can occur in 6 ways, but it being < 6 can be done in 5 ways).
Thus, we have:
P(Getting a number < 6 on that cube) =5/6 > 0.5
So it is likely to get a number < 6 on the considered cube. So this statement correctly describes the likelihood of its considered event.
It is unlikely that a number < 4 is obtained on the number cube.Ways to get a number on the considered cube = 6
Ways to get a number < 4 on the considered cube = 3
Thus, we get:
P(Getting a number < 4 on that cube) = 3/6 = 0.5
Thus, it is likely to get a number < 4 on that cube, so this option is wrong.
It is certain that an odd or even number is obtained on the number cubeYes it is certain, but we're considering only those options which correctly describe likelihood instead of certainity.
So, this option is not considerable.
It is unlikely that a number > 1 is obtained on the number cube.Ways to get a number on the considered cube = 6
Ways to get a number > 1 on the considered cube = 5
Thus, we get:
P(Getting a number > 1 on that cube) = 5/6 > 0.5
Thus, it is likely to get a number > 1 on that cube, so this option is wrong.
Thus, the statement that correctly descrives the likelilhood of an event based on the given numbered cube is: Option A: It is likely that a number less than 6 is occured.

Step-by-step explanation:

[tex]\frac{2}{15}[/tex] + [tex]\frac{1}{20}[/tex] = [tex]\frac{8}{60}[/tex] + [tex]\frac{3}{60}[/tex] = [tex]\frac{11}{60}[/tex]
Answer:
2/15 + 1/20 = 11/60
Step-by-step explanation:
1. Find the least common denominator or LCM of the two denominators:
15 and 20.
Steps to find LCM:
1. Find the prime factorization of 15
15 = 3 × 5
2. Find the prime factorization of 20
20 = 2 × 2 × 5
3. Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:
LCM = 2 × 2 × 3 × 5
LCM = 60
2. Next, find the equivalent fraction of both fractional numbers with denominator 60.
For the 1st fraction, since 15 × 4 = 60,
2/15 = 2 * 4 / 15 * 4 = 8/60
Likewise, for the 2nd fraction, since 20 × 3 = 60,
1/20 = 1 * 3 / 20 × 3 = 3/60
Add the two like fractions:
8/60 + 3/60 = 8 + 3/60 = 11/60

Upon review of production results, it was determined that 130 pieces out of 3,500 were "out of spec." What percent of the production was "out of spec"?
A. 0.03 percent .
B. 3.71 percent .
C. 30 percent
D. 37.1 percent
Answers
Answer:
Option B
Step-by-step explanation:
Given:
130 pieces of 3500 were out of specTo determine the percentage of the production was out of spec, we need to use the percentage formula (x/y × 100).
[tex]\implies \dfrac{x}{y} \times 100[/tex]
The value of "x" is the the number of pieces that were out of spec and the value of "y" is the total pieces in the production results.
[tex]\implies \dfrac{130}{3500} \times 100[/tex]
Simplify the expression to determine the percentage of the pieces that were out of spec.
[tex]\implies \dfrac{13000}{3500}[/tex]
[tex]\implies \dfrac{130}{35} = \dfrac{130 \div 5}{35 \div 5} = \dfrac{26}{7} = 3.714... \%[/tex]
When the percentage is estimated to nearest hundredth, we get 3.71%
(Option B)
Answer:
B) 3.71%
Step-by-step explanation:
[tex]\textsf{130 out of 3500}\sf =\dfrac{130}{3500}[/tex]
To convert to a percentage, multiply by 100:
[tex]\implies \sf \dfrac{130}{3500} \times 100\%=0.03714.. \times 100\%=3.71\%[/tex]
