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

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

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

                 ---------------------------------------------------------------------------

Answer: 202.5

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

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.

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]

Can you please explain this?

Answers

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) =

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
