Need help!
Answers
Answer:
-√64: rational
15 pi: irrational
46.86 repeated: rational
15/19: rational
-2√6: irrational
Step-by-step explanation:
From the picture that I used, I was able to find out which ones were rational and irrational.
-√64: rational because it equals to -8
15 pi: has "pi" in it
46.86 repeated: as long as it's repeated, it's rational
15/19: fractions are usually rational
-2√6: √6 is cannot be rationalized
Find an equation of the tangent line to the graph of
y = g(x) at x = 3 if g(3) = −6 and g'(3) = 4.
(Enter your answer as an equation in terms of y and x.)
Answers
The line tangent to g(x) at x = 3 is:
y = 4*x - 18
How to find the equation of the tangent line?
If we have a function y = f(x), the slope of the line tangent at the point x = a is given by f'(a).
In this case, we know that g'(3) = 4, so the slope of the line is 4.
Then the line is something like:
y = 4*x + b
To find the value of b we use the fact that this line must pass through the point (3, g(3))
And we know that g(3) = -6
Then this line must pass through the point (3, -6), replacing that we get:
-6 = 4*3 + b
-6 = 12 + b
-6 - 12 = b = -18
Then the tangent line is:
y = 4*x - 18

The step that is not allowed is (b) add the left side of equation 2 to the left side of equation 1
How to determine the disallowed step?The system of equations is given as:
2x - 3y = 12

Use calculus to find the area A of the triangle with the given vertices.
(0, 0), (4, 1), (2,6)
Answers
The area A of the triangle with the given vertices is 13 square units
How to determine the area A of the triangle with the given vertices?The vertices are given as
(0, 0), (4, 1), (2,6)
The area is calculated as
Area = 1/2 * |Ax(By - Cy) + Bx(Ay - Cy) + Cx(Ay - By)|
So, we have
Area = 1/2 * |0 * (1 - 6) + 4 * (0 - 6) + 2 *(0 - 1)|
Evaluate the sum of products
So, we have
Area = 1/2 * |-26|
Remove the absolute bracket
Area = 1/2 * 26
Evaluate the products
Area = 13
Hence, the area A of the triangle with the given vertices is 13 square units

A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the given event.
Answers
Missing Part:
a. A red ball is drawn
b. A white ball is drawn
Answer:
a. [tex]P(Red) = 0.4375[/tex]
b. [tex]P(White) = 0.3125[/tex]
Step-by-step explanation:
Given
[tex]Red = 7[/tex]
[tex]White = 5[/tex]
[tex]Yellow = 4[/tex]
First, we need to calculate the total
[tex]Total = Red + White + Yellow[/tex]
[tex]Total = 7+5+4[/tex]
[tex]Total = 16[/tex]
Solving (a): Probability of Red.
This is calculated by dividing number of red balls by the total
So:
[tex]P(Red) = \frac{Red}{Total}[/tex]
[tex]P(Red) = \frac{7}{16}[/tex]
[tex]P(Red) = 0.4375[/tex]
Solving (a): Probability of White.
This is calculated by dividing number of white balls by the total
So:
[tex]P(White) = \frac{White}{Total}[/tex]
[tex]P(White) = \frac{5}{16}[/tex]
[tex]P(White) = 0.3125[/tex]

Answer:
? = -2
Step-by-step explanation:
a + b = -2
so, now we need to find all (a + b) combinations in the large expression.
for example, we know
a = -2 - b
or b = -2 - a
and then
-b = 2 + a
but also
3b = -6 - 3a
so that
a - b = a + 2 + a = 2a + 2
therefore
(a + b)(a - b) = a² - b² = -2(2a + 2) = -4a - 4
(-4a - 4 - 12b - 36)/(-4a - 4 - 6a - 6b) =
(-4(a + 3b) - 40)/(-4a - 4 - 6(a + b)) =
(-4(a - 6 - 3a) - 40)/(-4a - 4 - 6×-2) =
(-4(-2a - 6) - 40)/(-4a + 8) =
(8a + 24 - 40)/(-4a + 8) = (8a - 16)/(-4a + 8) =
-2×(-4a + 8)/(-4a + 8) = -2

Raul received a score of 80 on a history test for which the class mean was 70 with standard deviation 10. He received a score of 75 on a biology test for which the class mean was 70 with standard deviation 2.5. On which test did he do better relative to the rest of the class?
Answers
Answer:
Raul performed better in the biology test
Step-by-step explanation:
Given
History
[tex]Score = 80[/tex]
[tex]Mean = 70[/tex]
[tex]Standard\ Deviation = 10[/tex]
Biology
[tex]Score = 75[/tex]
[tex]Mean = 70[/tex]
[tex]Standard\ Deviation = 2.5[/tex]
Required
Where did he perform better relative to other students
To do this, we simply calculate the z score in both tests and make comparison.
z score is calculated as thus;
[tex]z = \frac{x - Mean}{SD}[/tex]
For history;
[tex]z = \frac{80 - 70}{10}[/tex]
[tex]z = \frac{10}{10}[/tex]
[tex]z = 1[/tex]
For biology;
[tex]z = \frac{75 - 70}{2.5}[/tex]
[tex]z = \frac{5}{2.5}[/tex]
[tex]z = 2[/tex]
Since the z score in the biology test is greater than that of the history test, then he performed better in the biology test
Right triangle PQR is shown on the graph below. If the point (x, 7) lies on the line that goes through side of the trianglethen what should be the value of x?
A. -2
B. 5
C. -3
D. 3
Answers
Answer:
C. -3
Step-by-step explanation:
First, find the slope of side QR. Calculate the slope by finding the ratio of the difference between the y-coordinates and the difference between the x-coordinates of points Q and R.
The slope of side QR can be found as shown below.
Now, using the slope of side QR, draw a triangle RST similar to the right triangle PQR with S(x, 7) as one vertex.
Next, find the value of x as shown below.
Therefore, the value of x in the point (x, 7) is -3.

Amanda found a job that pays $450 per week. She must pay a fee to the employment agency of 15% of her first three week’s pay. How much does she need to pay the employment agency?
Answers
Answer:
192.5
Step-by-step explanation:
amount of money for one week = 450
amount of money for 3 weeks = 1350
15 percent of 1350 = 1350 x 15
= 19250
divide 19250 by 100
answer is 192.5
---------------------------------------------------------------------------
Process:
$450 per week——
amount of money for three week’s pay=3×450=1350
amount of money for the 15% fee=1350×15%=202.5
So the answer is 202.5
