Answer:

A. ​Yes, the point is​ defined, ​limit f(x) exists, and ​limit f(x) 0.

Step-by-step explanation:

Let be f(x) = \frac{x^{2}-25}{x-7}, a rational function is continuous at a value of x if and only if denominator is different from zero. In particullar, x-7 \neq 0.

Then, we find that function is continuous for every value of x except x = 7. Thus, the function is continuous at x = 0, which is evaluated below:

f(x) = \frac{(x+5)\cdot (x-5)}{x-7}

f(0) = \frac{(0+5)\cdot (0-5)}{0-7}

f(0) = \frac{(5)\cdot (-5)}{-7}

f(0) = \frac{-25}{-7}

f(0) = \frac{25}{7}

Thus, correct answer is A.

PLEASEE HEELLLP!!! I'LL GIVE BRAINLIEST!
Amanda [17]

Answer:

x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96

Step-by-step explanation:

The two angles above the horizontal line form a linear pair, so they are supplementary. Their measures add to 180 deg. That let's you find the value of x.

28x - 7 + 24x + 18 = 180

52x + 11 = 180

52x = 169

x = 169/52

x = 3.25

Now use the lower left angle and the upper right angle. They are vertical angles, so they are congruent. That allows you to solve for y.

12y + 30 = 24x + 18

We know that x = 3.25.

12y + 30 = 24(3.25) + 18

12y + 30 = 78 + 18

12y = 66

y = 66/12

y = 5.5

I don't know what the problem is asking for since you don't show.

x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96

Ray planted a square garden that covers an area of 200ft squared. How many feet of fencing does he need to surround the garden?
Dafna11 [192]

Ray needs 56.4 feet of fencing to surround the garden.

Step-by-step explanation:

Given,

Area of square garden = 200 ft²

As the garden is in square shaped.

Let a be the one side of square

Area = a²

a^2=200

Taking square root on both sides

\sqrt{a^2}=\sqrt{200}\\a=14.1 \ft

For the measure of fencing, we will find the perimeter.

Perimeter = 4a

Perimeter = 4(14.1) = 56.4 ft

Ray needs 56.4 feet of fencing to surround the garden.
