Answer:

Judy is the housewife.

Celia is the math teacher.

Betty is the truck driver.

Step-by-step explanation:

Let's analyze each sentence.

Judy can't drive and is married to the brother of the math teacher.

So if she can't drive, she's not the truck driver, and she's not the math teacher if she's married to the math teacher's brother. (Unless-- let's not go there.) Judy is the housewife.

Celia is the best friend of the truck driver.

This mean's Celia's not the truck driver - and she's not the housewife, because we decided Judy was the housewife, so Celia is the math teacher.

By process of elimination, Betty is the truck driver.

if one point is located at (-5,3) and another point is located at (7,-4). find the distance between the points. round to the nea

Novay_Z [31]

Answer:

13.9

Step-by-step explanation:

Use the distance formula:

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\$

The square root of 193 rounded to the nearest tenth is 13.9.

What numbers add to 2 and multiply to -56

marta [7]

The numbers are irrational, so they can't be exactly written down
using only digits.

In exact form, they are

   1 + √57
and
   1 - √57 .

In rounded form, they are

   8.54983
and
    -6.54983 .

What is the maximum number of possible extreme values for the function, f(x) = х2 -7x – 6?

timama [110]

Answer:

Only one extreme value of f(x) is possible.

Step-by-step explanation:

We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)

Now. the condition for extreme values of f(x) is $\frac{df(x)}{dx} =0$

Hence, differentiating both sides of equation (1) with respect to x, we get

$\frac{df(x)}{dx} = 2x -7$ = 0

⇒ x = 3.5.

So there is only one value of x for which f(x) has extreme value which is x = 3.5.

Therefore, only one extreme value of the given function is possible. (Answer)

I need the RIGHT answer to this please. :)

KATRIN_1 [288]

A is the answer. It has no repeating x points buy it repeats on the y coordinate, which is okay. The answer is A just to say it again.

If tan of angle theta = 11/60 , what is the value of cot angle theta?

UkoKoshka [18]

The tangent and cotangent functions of the angle are related such that one is the reciprocal of the other. From the given tan theta = 11 / 60. The reciprocal of this number is 60 / 11. This value is also the cotangent of the angle. Thus, the cotangent angle theta is 60 / 11.
