Answer:

[tex](0, log_{b}(-k)), k < 0[/tex]

Step-by-step explanation:

[tex]y = \log_{b}(a - k)[/tex]

To find the y-intercept, set a = 0 and solve for y.

[tex]y = \log_{b}(0 - k)\\y = \log_{b}(-k)[/tex]

This equation is undefined for k ≥ 0.

There is a y-intercept only if k < 0. Only then can the argument of the log function be positive.

The y-intercept is at

[tex]\mathbf{(0, log_{b}(-k)), k < 0}[/tex]

For example, if b = 2 and k = -3, log₂(3) = 1.585

The intercept is at (0, 1.585).

Answer:

Adrian needs to pay $5 for all the fruit.

Step-by-step explanation:

Consider the provided information.

Grapes cost  $2.35 per pound, oranges cost $0.99 per  pound, and apples cost $1.65 per pound.

In order to find how much Adrian needs to pay we need to add $2.35, $0.99 and $1.65.

[tex]\$2.35 + \$0.99 + \$1.65=\$4.99[/tex]

Now round $4.99 to the nearest whole number.

[tex]\$4.99\approx\$5[/tex]

Hence, Adrian needs to pay $5 for all the fruit.

Answer:

The slope for the given points is - 2  , and  y- intercept is 5

Step-by-step explanation:

Given points as :

( - 1 , 7 )  and  ( 0 , 5 )

Now slope of line in points form as

Slope = m = [tex]\dfrac{y_2-y_1}{x_2-x_1}[/tex]

or, m =  [tex]\dfrac{5 - 7}{0 + 1}[/tex]

or, m = - 2

so, Slope of line is - 2

Now equation of line is given as

y - [tex]y_1[/tex] = m × ( x -  [tex]x_1[/tex] )

or, y - 7 = ( - 2 ) × ( x + 1)

or, y - 7 = - 2 x - 2

Or, equation of line is

y = - 2 x + 5

Now, for y - intercept , x = 0

So, from line equation

y = - 2 × 0 + 5

Or, y = 0 + 5

∴ y = 5

Hence The slope for the given points is - 2  , and  y- intercept is 5  Answer

Answer:

The slope is -2.

Answer:

Critical value is -1.98.

Step-by-step explanation:

Given:

The value of alpha is, [tex]\alpha=0.024[/tex]

Now, in order to find the critical value, we need to subtract alpha from 1 and then look at the z-score table to find the respective 'z' value for the above result.

The probability of critical value is given as:

[tex]P(critical)=1-\alpha=1-0.024=0.976[/tex]

So, from the z-score table, the value of z-score for probability 0.976 is 1.98.

Now, in a left tailed test, we multiply the z value by negative 1 to arrive at the final answer. We do so because the area to the left of mean in a normal distribution curve is negative.

So, the z-score for critical value 0.024 in a left tailed test is -1.98.

The critical value for α = 0.024 in a left-tailed test is -1.98.

To find this value, we locate α = 0.024 in the z-table. The z-table is a table that shows the probability of obtaining a z-score less than or equal to a certain value.

The z-score is a measure of how many standard deviations a particular data point is away from the mean of the population.

Here is the critical value for α = 0.024 in a left-tailed test: -1.98

In this case, we are looking for the z-score that corresponds to a probability of 0.024. This z-score is -1.98. Therefore, if our test statistic is less than or equal to -1.98, we will reject the null hypothesis.

Answer:

y = -0.5x -2

Step-by-step explanation:

We have to find a line perpendicular to the line y = -2x -3.

Let the required line will have slope m so ,

-2m = 1

m = -0.5.

So, the required line will have the slope -0.5.

Now, let the line be y = -0.5x + c.

This line is passing through (-2,-1), So putting this point in the line we will get

-1 = 1 + c

c = -2 .

So, the required line is

y = -0.5x -2.

Answer: 1/8

Step-by-step explanation: To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100.

So here, 12.5% can be written as the ratio 12.5 to 100 or 12.5/100.

To write 12.5/100 in lowest terms, first multiply the numerator and the denominator by 10 to get rid of the decimal. When we do this, we get the fraction 125/1000.

Now, we divide the numerator and the denominator of 125/1000 by the greatest common factor of 125 and 1,000 which is 125 and we end up with the equivalent fraction which is 1/8.

Therefore, 12.5% is equivalent to 1/8.

Step-by-step explanation:

After 14 weeks, both Megan and Conner will have saved the same amount.

Step-by-step explanation:

Amount Megan have = $50

Amount saved each week = $5.50

Amount Conner have = $18.50

Amount saved each week = $7.75

Let,

x be the number of weeks.

According to given statement;

M(x) = 50+5.50x    Eqn 1

C(x) = 18.50+7.75x   Eqn 2

For amount to be same;

Eqn 1 = Eqn 2

[tex]50+5.50x=18.50+7.75x\\50-18.50=7.75x-5.50x\\31.50=2.25x\\2.25x=31.50\\[/tex]

Dividing both sides by 2.25

[tex]\frac{2.25x}{2.25}=\frac{31.50}{2.25}\\x=14[/tex]

Answer:

680$

Step-by-step explanation:

If this is a 64% discount, the price 244.80 is 36% of the original price

244.8 = 36%    -Divide by 36 on both sides

6.8 = 1%            - Times by a hundred

680 = 100%

The original price is 680$

To find the original price of the sofa given a 64% discount, divide the sale price by the discount percentage and subtract it from 100%.

To find the original price, we need to determine what the discount percentage represents in terms of the original price. Since the sale price is 64% of the original price, the discount is 100% - 64% = 36%. Let's represent the original price as x:

36% of x = $ 244.80

To solve this equation, we can convert 36% to the decimal form by dividing it by 100: 36/100 = 0.36. Now we can solve for x:

0.36x = $ 244.80

Dividing both sides of the equation by 0.36, we get:

x = $ 244.80 / 0.36 = $ 680

Therefore, the original price of the sofa was $ 680.

Answer:

y = 43x − 25

Step-by-step explanation:

Evaluate the function at x=1:

f(x) = 12x³ + 3x² + x + 2

f(1) = 12 + 3 + 1 + 2

f(1) = 18

Find the slope of the tangent line at x=1:

f'(x) = 36x² + 6x + 1

f'(1) = 36 + 6 + 1

f'(1) = 43

Point-slope form:

y − y₀ = m (x − x₀)

y − 18 = 43 (x − 1)

Convert to slope-intercept form:

y − 18 = 43x − 43

y = 43x − 25

To find the linear approximation for the function f(x) = 12x^3 + 3x^2 + x + 2 at x = 1, we can use the equation for the linear approximation. First, we need to find the derivative of the function and then plug in the values into the formula. The linear approximation is f(1).

To find the linear approximation for the function f(x) = 12x^3 + 3x^2 + x + 2 at x = 1, we can use the equation for the linear approximation:

() ≈ () + '()( − )

First, we need to find '(), which is the derivative of the function. Taking the derivative of f(x) gives us:

'() = 36^2 + 6 + 1

Next, we plug in x = 1 into the first equation:

(1) ≈ (1) + '(1)(1 − 1)

Simplifying, we have:

(1) ≈ (1)

So, the linear approximation for f(x) at x = 1 is f(1).

Answer:

cot(x)

Step-by-step explanation:

csc(x) = 1/sin(x)

cos(x)*csc(x) = cos(x)*1/sin(x)

cos(x)*csc(x) = cos(x)/sin(x)

cos(x)*csc(x) = cot(x)

----

abbreviations

csc = cosecant

cos = cosine

sin = sine

cot = cotangent

To simplify cos x csc x, we can replace csc x with 1/sin x based on the trigonometric identity. This will give us cos x/sin x, which is the same as cot x based on the trig identities.

The question is asking us to simplify the expression cos x csc x. To do this, we can use the trigonometric identity sin = 1/csc, which tells us what csc x is in terms of sin x.

So if that is the case, we can rewrite csc x as 1/sin x and replace csc x in the original expression giving us cos x * (1/sin x) or equivalently cos x/sin x.

And if we look at our trigonometric identities again, we can find that cos x/sin x is the same as cot x, our final simplified expression.

Answer: 53, 54, 55, and 56

Step-by-step explanation: This problem states that the sum of 4 consecutive numbers is 218 and it asks us to find the numbers.

4 consecutive numbers can be represented as followed.

X ⇒ first number

X + 1 ⇒ second number

X + 2 ⇒ third number

X + 3 ⇒ fourth number

Since the sum of our 4 consecutive numbers is 218, we can set up an equation to represent this.

X + X + 1 + X + 2 + X + 3 = 218

On the left side of the equation, we can combine our x's and our numbers.

4x + 6 = 218

      -6     -6   ← subtract 6 from both sides of the equation

4x = 212

÷4    ÷4   ← divide both sides of the equation by 4

 X = 53

X ⇒ first number   = 53

X + 1 ⇒ second number   = 54

X + 2 ⇒ third number   = 55

X + 3 ⇒ fourth number   = 56

Therefore, our 4 consecutive numbers are 53, 54, 55, and 56.
