f(x)+-3x+5 for f(-2)​

Answer:

Twice

Step-by-step explanation:

It is twice because when you get your answer of the subtraction part, you divide by 2 or 2/1 and so you got to do K.C.F.

so in the end you would be multiplying by 1/2 or 2

Answer: Half

Think of an example like comparing \(72 \div 2\) versus \(72\)

I replaced the complicated stuff in the parenthesis with "72", and we're dealing with the same kind of problem.

Using a calculator or long division, \(72 \div 2 = 36\) which is half of 72.

Dividing by 2 is the same as multiplying by the fraction 1/2

\(\frac{1}{2}*72 = 36 \ \text{ and } \ 72 \div 2 = 36\)

Answer:

the b believes in me

Step-by-step explanation:

B)75km  etc

   1hr

\(\frac{75 \text{ km}}{1 \text{ hr}} \times \frac{1000 \text{ m}}{1 \text{ km}} \times \frac{1 \text{ hr}}{60 \text{ min}} \times \frac{1 \text{ min}}{60 \text{ sec}}\)

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

Explanation:

We'll use the following facts (either memorized or written on a reference sheet somewhere)

Each of those equations will form conversion factors to help us go from km/hr to m/s. Each conversion factor is a fraction connecting the two sides of the equation. Example: The equation 1000 m = 1 km forms the conversion factor of \(\frac{1000 \text{ m}}{1 \text{ km}}\)

In choice B, notice how the fractions are set up. The "km" units cancel when dividing. The same goes for the "hr" and "min" units.

Check out the screenshot below where I show this cancellation in action. The color-coding helps show how the terms pair up and cancel.

Choice A comes close to what choice B is saying, but we don't have the "min" units cancel. So choice A is eliminated as an answer.

Choices C and D are also eliminated because of the "75 km" in the denominator. It should be 1 km.

y=3/x, y=12x, y=1/3x, x>0 ; using the concept of area under the curve its area = 3 ln 6,

The region between a curve and the -axis is referred to as the "area under a curve." This region may be wholly above the -axis, entirely below the -axis, or somewhere in between. The area under a curve in calculus is a picture of an integral.

The region enclosed by the curve, the axis, and the boundary points is referred to as the "area under the curve." Using the coordinate axes and the integration formula, the area under the curve has been determined as a two-dimensional area. The area of the asymmetric plane form in a two-dimensional array is provided by the region beneath the curve.

Given that,

y = 3/x, y = 12x, y = 1/3x, x > 0

Now, area:

=  \(\int\limits^{1/2}_0 {12x - (x/3)} dx + \int\limits^3_{1/2} [{(3/x)- (x/3)}] \, dx\)

= \([\frac{35}{6} x^2]^{1/2}_0 + [ 3 \ln |x| - (x^2/6)]^3_{1/2}\)

= \(\frac{35}{24} + 3\ln 3 + 3\ln 2 - \frac{35}{24}\)

= \(3 [ \ln 3 + \ln 2]\)

= \(3 \ln 6\)

So, area = \(3 \ln 6\)

Given quadratic equation has same solution set as -x=x²+12x+36 i.e. C.

A second-degree algebraic equation in x is a quadratic equation. Ax2 + bx + c = 0 is the quadratic equation in its standard form, with a and b acting as coefficients, x acting as the variable, and c acting as the constant term.

The coefficient of x2 must not be zero (a 0) for an equation to qualify as a quadratic equation. The x2 term comes first, followed by the x term, and finally the constant term when stating a quadratic equation in standard form. Instead of being written as fractions or decimals, the numerical values a, b, and c are frequently expressed as integral values.

Now,

Given equation is √-x=x+6

-x = (x+6)²

-x = x² +36+12x

x² + 11x + 36 = 0

As it is same quadratic equation as given in option C.

Hence,

The correct choices are B and C:

B. Shift the graph of y=∣x∣ right by 10 units.

C. Shift the graph of y=∣x∣ down by 10 units.

To graph f(x) = |-(x-10)| using the graph of y=|x|, we need to apply a series of transformations:

A. Reflect the graph of y=|x| across the y-axis: This will give us the graph of y=|-x|.

B. Shift the graph of y=|-x| right by 10 units: This will give us the graph of y=|-x+10|.

C. Shift the graph of y=|-x+10| down by 10 units: This will give us the graph of y=|-x+10|-10.

Therefore, to obtain the graph of f(x) = |-(x-10)| from the graph of y=|x|, we need to reflect the graph across the y-axis, shift it 10 units to the right, and 10 units down.

The volume of the new cone is 0.507 times the volume of the old cone.

What is meant by volume?

Volume is a measure of the space occupied by a three-dimensional object or substance. It is usually measured in cubic units such as cubic meters, cubic centimeters, or cubic feet and can be calculated using various formulas depending on the shape and size of the object.

What is a cone?

A cone is a three-dimensional geometric shape that tapers smoothly from a flat circular base to a point called the apex. It has one circular base, one curved surface, and a vertex or apex.

According to the given information

Let's start by finding the radius of the original cone using its diameter:

Radius = Diameter/2 = 48/2 = 24

Now, we can use the formula for the volume of a cone:

Volume of original cone = (1/3) * pi * r² * h

= (1/3) * pi * 24² * 18

= 54,432 pi

The new cone has a diameter of 48x and a length of 18x. So, its radius and height are:

Radius = (48x)/2 = 24x

Height = 18x

The volume of the new cone is:

Volume of new cone = (1/3) * pi * (24x)² * (18x)

= 27,648 x³ pi

To compare the volumes, we can divide the volume of the new cone by the volume of the old cone:

Volume of new cone / Volume of old cone = (27,648 x³ pi) / (54,432 pi)

= 0.507 x³

Therefore, the volume of the new cone is 0.507 times the volume of the old cone.

Answer:

  x = 65°

  y = 50°

  z = 65°

Step-by-step explanation:

130° + y = 180°

y = 50°

115° + z = 180°

z = 65°

x + y + z = 180°

x + 50° + 65° = 180°

The normal approximation is used to estimate probabilities in a medication study for weight gain as a side effect, providing insights into specific outcomes.

To approximate the probabilities using the normal approximation to the binomial, we need to know the success probability (percent of patients gaining weight) and the number of patients involved in the study. Let's denote the success probability as p and the number of patients as n.

(a) To calculate the probability that exactly k patients will gain weight, we can use the formula for the binomial distribution:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

However, since we are using the normal approximation, we can approximate it as:

P(X = k) ≈ P(k - 0.5 < X < k + 0.5)

(b) To calculate the probability that no more than k patients will gain weight, we can sum the probabilities from 0 to k:

P(X ≤ k) ≈ P(0.5 < X < k + 0.5)

(c) To calculate the probability that at least k patients will gain weight, we can subtract the probability of the complement event (less than k patients) from 1:

P(X ≥ k) ≈ 1 - P(X < k + 0.5)

These approximations rely on the assumption that n is sufficiently large and that p is not too close to 0 or 1. The result suggests that we can estimate the probabilities of specific outcomes in the medication study using the normal distribution, providing an approximate understanding of the likelihood of different scenarios.

Answer:

\(T_f=9^{\circ} F\)

Step-by-step explanation:

It is given that,

Initial temperature, \(T_i=3^{\circ} F\)

The decrease in temperature when she woke up is, \(\Delta T=6^{\circ} F\)

We need to find the temperature when Ava woke up.

Change in temperature = final temperature-initial temperature

\(6\ ^{\circ}F=T_f-3^{\circ}F\\\\T_f=9^{\circ} F\)

So, when she woke up the temperature was 9°F.

The temperature when Ava woke up is -3°F

Integers come in three types:

Given:

When Ava went to bed, the temperature was 3°F.

and, When she woke up, the temperature had decreased by 6°F.

So, the temperature when Ava woke up

= 3 - 6

= -3°F
