Answer:

slope = - [tex]\frac{3}{11}[/tex]

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 14, 3 ) and (x₂, y₂ ) = (- 3, 0 )

m = [tex]\frac{0-3}{-3-(-14)}[/tex] = [tex]\frac{-3}{-3+14}[/tex] = - [tex]\frac{3}{11}[/tex]

Answer:

[tex]\csc(\theta)[/tex]

Step-by-step explanation:

[tex]\cot(\theta)=\dfrac{1}{\tan(\theta)}=\dfrac{\cos(\theta)}{\sin(\theta)}[/tex]

[tex]\sin^2(\theta)+\cos^2(\theta)=1[/tex]

[tex]\implies \sin(\theta)+\cos(\theta)\times\cot(\theta)=\sin(\theta)+\cos(\theta)\times\dfrac{\cos(\theta)}{\sin(\theta)}[/tex]

[tex]=\sin(\theta)+\dfrac{\cos^2(\theta)}{\sin(\theta)}[/tex]

[tex]=\dfrac{\sin^2(\theta)}{\sin(\theta)}+\dfrac{\cos^2(\theta)}{\sin(\theta)}[/tex]

[tex]=\dfrac{\sin^2(\theta)+\cos^2(\theta)}{\sin(\theta)}[/tex]

[tex]=\dfrac{1}{\sin(\theta)}[/tex]

[tex]=\csc(\theta)[/tex]

Answer:

Step-by-step explanation:

f(x) = x⁴ - 8x² + 16

f'(x) = 4x³ - 16x = 4(x³ - 4x) = 4x(x² - 4) = 4x(x - 2)(x + 2)

f'(x) = 0, x = 2, -2

f"(x) = 4(3x² - 4)

f''(0) = -16 < 0, f""(2) = f''(-2) 3(12 - 4) > 0

so f(2) and f(-2) are minimum values

f(0) is maximum value.

f(0) = 16, f(2) = f(-2) = 2⁴ - 8*2² + 16 = 0

Maximum = 16, minimum value = 0

-∞ < x < -2, f'(x) < 0

-2 < x < 0, f'(x) > 0

0 < x < 2, f'(x) < 0

2 < x < ∞, f(x) > 0

increase: (-2, 0) and (2, ∞)

decrease: (-∞, -2) and (0, 2)

Answer:

Step-by-step explanation:

A rational number that doesn't go on forever. Like Pi, that is not a rational number. But, 2.3 would be a rational number.

72/100 = .72 which is a rational number

Like I said before Pi goes on forever so it is NOT a rational number.

1 1/3. One is a rational number but 1/3 is o.3 with the 3 repeating forever. So it WOuld NOT be a rational number.

8/526 has numbers that go on forever so it would NOT be a rational number.

0.212212221 goes on forever. The three dots (...) signal that the decimal goes on. SO it would NOT be a rational number.

5/9= 0.555555555555555555555... the 5 goes on forever making it NOT a rational number.

Answer:

60% increase

Step-by-step explanation:

The formula for percent change: new value-old value and divide this by the old value. Then multiply by 100

So, 72-45=27

27/45=0.6

0.6*100=60

60%

Answer:

the answer is 60

Step-by-step explanation:

first you need to round 5.7 to the nearest whole number

6

after that multiply by 10 and you've done it

The temperature after 22 minutes is 75.75 degrees

Given the resulting exponential model for the temperature, t, after m minutes can be approximated by the model t = 133(0.85)^m + 72.

If the time used is 22 minutes, the required temperature dring this time is expressed as:

t = 133(0.85)^22 + 72

t = 3.725 + 72

t = 75.75

Hence the temperature after 22 minutes is 75.75 degrees

Answer:

mean: 14

median: 15

mode: 6, 15, 18

Step-by-step explanation:

For the mean, you add up all the numbers and divide by the number of numbers there are. There are 7 numbers here, so add and divide by 7.

For the median, you line the numbers up from least to greatest.

6, 6, 15, 15, 18, 18, 20

and find the middle number, which is 15.

For the mode, you have to find the number that repeats the most. For this set of numbers, it's 15, 18, and 6. Hope that helps!

Answer:

Mean  = 14

Median = 15

Mode = 6, 18, 15

Answer:

  P(B) = 0.20

Step-by-step explanation:

For these events, which are not independent or mutually exclusive, the relation between the various probabilities is ...

  P(A or B) = P(A) +P(B) -P(A and B)

Solving for P(B), we find ...

  P(B) = P(A or B) +P(A and B) -P(A)

  P(B) = 0.77 +0.13 -0.7 = 0.20

The probability of B is 0.20.

__

Additional comment

The formula applies to independent and mutually exclusive events, as well. For independent events, P(A and B) = P(A)·P(B). For mutually exclusive events, P(A and B) = 0.

Answer:

D

Step-by-step explanation:

if 15*5 is 75, than 75 is 5 times bigger than 15

The equation 15 × 5 = 75 represented the statement The number 75 is 5 times as many as 15, so option D is correct.

The equals sign is used in equations to indicate the equality of two expressions in a formula. It is a mathematical statement that says, "this is equivalent to that," in other words. There appears to be an equal sign in the middle, a mathematical expression on the right, and a mathematical expression on the left.

Given:

15 × 5 = 75

Assume the number is x = 5,

Here, you can see that x is 15 times to equal 75,

So, the above statement can be written as the number 75 is 5 times 15.

Answer:

The area would be 32

Step-by-step explanation:

Let's call the side lengths a and b, so then therefore a + b =  12

after this, we know that the length of a is 4, from the distance formula, and so the length of b is 8, so the area is 4*8 which is 32

Step-by-step explanation:

Answer:

larger #=32

smaller #= 26

Step-by-step explanation:

We can solve this by using x for the larger number.

larger #= x

smaller #= x-6

x+x-6=58

2x-6=58

2x=64

x=32

The larger number is 32. To find the smaller # you simply substitute the variable x-6 which is now 32-6 which is 26.

Hope this helps!

Answer:

smaller number = 26

larger number = 32

Step-by-step explanation:

x = smaller number

y= larger number =x+6

so

x+y=58

x+6+x= 2x+6=x58

2x=58-6=52

x=522= 26

y=x+6=26+6 = 32

checking

x+y=58

26+32= 58

Explanation:

area  = length*width

area = (1/4)*(2/3)

area = (1*2)/(4*3)

area = 2/12

area = 1/6 of a square inch

This confirms that choice A is a correct set of dimensions to lead to an area of 1/6 of a square inch.

Choice B leads to (1/3)*(1/3) = 1/9 which means we can rule it out.

Choice C leads to 1/36 and choice D leads to 1/24.

=========================================================

Explanation:

x = score on the fifth exam

The set {78,93,82,76,x} sums to 78+93+82+76+x = 329+x

Divide this over 5 since we have five total scores

(329+x)/5

That fraction represents the final average grade

Susan wants this average to be at least 85

[tex]\text{average} \ge 85\\\\\frac{329+x}{5} \ge 85\\\\329+x \ge 5*85\\\\329+x \ge 425\\\\x \ge 425-329\\\\x \ge 96\\\\[/tex]

Therefore, Susan must get a 96 or higher on the next exam if she wants to aim for the average to be 85 or larger.

In other words, the lowest grade she can get is a 96
