Answer:

$\lim_{x\to 0^+} \tan(x) - \frac{1}{x^2} = -\infty$

Step-by-step explanation:

$\lim_{x\to 0^+} \tan(x) - \frac{1}{x^2} = \lim_{x\to 0^+} \tan(x) - \lim_{x\to 0^+} \frac{1}{x^2}$

and

$\lim_{x\to 0^+} \tan(x) = \tan(0) = 0$

$\lim_{x\to 0^+} \frac{1}{x^2} = +\infty$

Therefore,

$\lim_{x\to 0^+} \tan(x) - \frac{1}{x^2} = -\infty$

Grace and Zoe like to jump rope grades jump 66 times a minute Zoe jumps 56 times a minute they both Count Their jumps today and

san4es73 [151]

Answer:

Grace jumps for 9 minutes.

Zoe jumps for 12 minutes.

Step-by-step explanation:

Let the time for which Grace jumps the rope = $x$ minutes

Let the time for which Zoe jumps the rope = $y$ minutes

As per question statement:

$x+y=21 ..... (1)$

Number of times Grace jumps in one minute = 66

Number of times Zoe jumps in one minute = 56

Number of times Grace jumps in $x$ minutes = 66

Number of times Zoe jumps in $y$ minutes = 56

As per question statement:

$66x+56y=1266 ...... (2)$

Multiplying equation (1) with 66 and subtracting equation (2) from it:

$10y = 1386 - 1266\\\Rightarrow 10y=120\\\Rightarrow y =\bold{12\ min}$

By equation (1):

$x=21-12=\bold{9\ min}$

Therefore, the answer is:

Grace jumps for 9 minutes.

Zoe jumps for 12 minutes.

Suppose a uniform random variable can be used to describe the outcome of an experiment with the outcomes ranging from 50 to 80.

taurus [48]

Answer:

The correct answer is $\frac{1}{3}$ = 0.33.

Step-by-step explanation:

A uniform random variable is used to describe the outcome of an experiment with the parameters being 50 and 80.

Probability density function = f(x) = $\left \{ {{\frac{1}{b-a} , a$

Here a = 50 and b = 80.

We need to find the value of probability of this given experiment in an outcome less than 60.

∴ P(X<60) = $\frac{60-50}{80-50} = \frac{10}{30} = \frac{1}{3}$ = 0.33.

Thus the required probability is given by 0.33.

After working 80 hours at his job, Tyshawn earned a total of $1080. How much does Tyshawn earn

bogdanovich [222]

The amount Tyshawn earn per hour is $13.5

<h3>Ratio and proportion</h3>

Fractions are written as a ratio of two integers

If after working 80 hours at his job, Tyshawn earned a total of $1080, then;

80 hrs = $1080

In order to calculate the amount earned per hour

Amount per hour = 1080/80

Amount per hour = $13.5

Hence the amount Tyshawn earn per hour is $13.5

For the point P(21, 24) and Q(26, 27) , find the distance d(P, Q) and the coordinates of the midpoint M of the segment PQ

aleksley [76]

Answer:

d(P,Q) = 5.83 units

Mid-point = (23.5,25.5)

Step-by-step explanation:

Given points are:

P(21,24) = (x1,y1)

Q(26,27) = (x2,y2)

The distance formula is given by:

$d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point.

Putting the given values in the formula

$d(P,Q) = \sqrt{(26-21)^2+(27-24)^2}\\= \sqrt{(5)^2+(3)^2}\\=\sqrt{25+9}\\=\sqrt{34}$

$= 5.830952$

Rounding off: 5.83 units

The mid-point of two points is given by the formula:

$M = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})$

Putting the values:

$M = (\frac{21+26}{2} , \frac{24+27}{2})\\=(\frac{47}{2} , \frac{51}{2})\\=(23.5, 25.5)$

Hence,

d(P,Q) = 5.83 units

Mid-point = (23.5,25.5)
