Answers

B bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Answer:

The correct is B) [tex]g(x)=- x^{2}-3[/tex]

Step-by-step explanation:

In provided graph f(x) is x² which is equation of parabola

this is shown by blue graph

we need to find the equation of red graph which is denoted by g(x)

It can be seen from graph that g(x) is downward so, in this equation coefficient must be in negative.

In part A) [tex]g(x)= (-x)^{2}+3[/tex]

so, [tex]g(x)= x^{2}+3[/tex]

here is not negative coefficient

In part B) [tex]g(x)=- x^{2}-3[/tex]

here is negative coefficient

This shows downward direction of parabola.

and negative 3 shows the shifting of parabola downward by 3 units.

Hence, this condition matches only option B)[tex]g(x)=- x^{2}-3[/tex]

In part C) [tex]g(x)=(-x)^{2}-3[/tex]

so, [tex]g(x)= x^{2}-3[/tex]

here is not negative coefficient

In part D) [tex]g(x)=-x^{2}+3[/tex]

since, here is negative coefficient  

This shows downward direction of parabola.

and positive 3 shows the shifting of parabola upward by 3 units.

So, the correct is B) [tex]g(x)=- x^{2}-3[/tex]

470.47 in expanded form​

Answers

Four hundred seventy and forty seven hundredth

Final answer:

The number 470.47 in expanded form is expressed as the sum of each digit's value according to its place value, which is 400 + 70 + 0 + 0.4 + 0.07.

Explanation:

You've asked to write the number 470.47 in expanded form. Writing a number in expanded form is a way of expressing the number as the sum of the values of each digit according to its place value. Here is how you convert 470.47 into expanded form:

400 (4 in the hundreds place is worth 400)

70 (7 in the tens place is worth 70)

0 (0 in the ones place doesn't add any value)

0.4 (The digit 4, after the decimal, represents 4 tenths or 0.4)

0.07 (The digit 7, in the hundredths place, represents 7 hundredths or 0.07)

Therefore, 470.47 in expanded form is: 400 + 70 + 0 + 0.4 + 0.07.

it takes 91 kiloliters of water to fill the hendersons swimming pool. how much is this in liters

Answers

Answer:

91,000 Liters

Step-by-step explanation:

1 Kiloliters =  1,000 liters

91 times 1,000 = 91,000

To convert 91 kiloliters to liters, multiply 91 by 1,000, which equals 91,000 liters. Therefore, 91 kiloliters of water is equal to 91,000 liters.

To convert kiloliters to liters, you need to know the conversion factor. 1 kiloliter (kL) is equivalent to 1,000 liters (L). Therefore, to convert 91 kiloliters to liters, you simply multiply 91 by 1,000.

The calculation would be as follows:
91 kL × 1,000 L/kL = 91,000 L

So, 91 kiloliters of water is the same as 91,000 liters of water.

Fran solved the equation 42 = x + 23. Although her final answer was correct, she could have found it in a simpler way. Which sentence best explains why?

Answers

Final answer:

The easier way to solve the equation 42 = x + 23 is by subtracting 23 from both sides of the equation. This will result in the value of x being 19. The process of isolating the variable on one side of the equation is important for finding the value of the variable.

Explanation:

In this mathematical equation, 42 = x + 23, to find the value of x, we need to isolate x on one side of the equation. The operation involved is subtraction. We subtract 23 from both sides of the equation. This process is important to maintain the equality of the equation. By doing this operation, both sides of the equation still balance. After subtracting 23 from both sides, we get x = 42 - 23, resulting in x = 19.

In order to find the value of x, Fran needs to isolate it on one side of the equation. To do this, she can subtract 23 from both sides of the equation, resulting in 42 - 23 = x. Simplifying further, she finds that x = 19.

Alternatively, Fran could have recognized that 42 - 23 equals 19 and immediately concluded that x = 19, saving her the need to do the subtraction step.

Therefore, the sentence that best explains why Fran could have found the answer in a simpler way is that she could have recognized the subtraction step as an immediate result and skipped it.

Step-by-step explanation:

1)

[tex]1 +\frac{cos^2\theta}{cot^2\theta(1-sin^2\theta)}= 9 sec^2\theta[/tex]

We need to prove this identity.

We know:

[tex]cos^2\theta + sin^2\theta = 1\\=> cos^2\theta = 1- sin^2\theta[/tex]

and

[tex]\frac{1}{cot^2\theta } = tan^2\theta \\and\\tan^2\theta = \frac{sin^2\theta}{cos^2\theta}[/tex]

Using these to solve the identity

[tex]1 +\frac{cos^2\theta}{cot^2\theta(cos^2\theta)}= 9 sec^2\theta\\1 +\frac{1}{cot^2\theta} = 9 sec^2\theta\\1+tan^2\theta = 9 sec^2\theta\\1+\frac{sin^2\theta}{cos^2\theta} = 9sec^2\theta\\\\\frac{cos^2\theta+sin^2\theta}{cos^2\theta} = 9sec^2\theta\\\frac{1}{cos^2\theta}=9sec^2\theta \\sec^2\theta \neq 9sec^2\theta[/tex]

So, this is not an identity.

2)

[tex]20sin\theta(\frac{1}{sin\theta} -\frac{cot\theta}{sec\theta}) =20sin^2\theta\\[/tex]

We need to prove this identity.

We know:

Using this to solve the identity

[tex]20sin\theta(\frac{1}{sin\theta} -\frac{cot\theta}{sec\theta}) =20sin^2\theta\\\\Putting\,\,values\,\,\\ 20sin\theta(\frac{1}{sin\theta} -\frac{cos^2\theta}{sin\theta}) =20sin^2\theta\\ 20sin\theta(\frac{1-cos^2\theta}{sin\theta}) =20sin^2\theta\\1-cos^2\theta = sin^2\theta\\ 20sin\theta(\frac{sin^2\theta}{sin\theta}) =20sin^2\theta\\Cancelling\,\, sin\theta \,\,over \,\,sin\theta\\20sin^2\theta=20sin^2\theta[/tex]

So, this is an identity.

So, option C Only second equation is an identity is correct.

Blank is a measure of how heavy a object is

Answers

Answer:

Weight.

Step-by-step explanation:

A weight is a measure of the pull of gravity on an object. This is the correct answer to this question.

Hope this helps!!!

Kyle.

Weight is a measure of the gravitational force on an object and varies by location, expressed in units like pounds or kilograms, while mass is the total quantity of matter in an object and is constant regardless of location.

Weight is a measure of how heavy an object is. When someone refers to how heavy something feels, such as an imaginary object causing a person to bend over due to its heaviness, they are describing the object's weight. Weight is determined by the force of gravity acting on the mass of the object and varies depending on where the object is located. It is commonly expressed in pounds and ounces, kilograms and grams, or tons.

On the other hand, mass is a measure of the total quantity of matter an object contains. It is an intrinsic property of the object and does not change regardless of its location—whether it's on Earth, in orbit, or on the Moon. Mass is commonly measured in kilograms or grams.

For example, when determining what unit of measurement to use to weigh a large dog, we would choose a unit of weight, such as pounds or kilograms. It is important to remember that volume is different from both mass and weight. Volume measures the amount of physical space an object occupies and is not the same as weight.

Answer:

Step-by-step explanation:

I'm thinking the last one

While 'yeet' is not an academically defined term, it typically refers to the act of throwing something with force. Drawing from a story on LibreTexts, one can learn the technique for effectively throwing objects such as a horseshoe, which involves grip, stance, focus on the target, and a smooth release.

To throw a horseshoe effectively, similar to learning how to "yeet," one must:

Hold the horseshoe in a comfortable but firm grip with your thumb along one of the sides of the horseshoe.

Stand at the designated throwing line and focus on the stake you're aiming at.

Swing your arm forward smoothly and release the horseshoe when your hand is about waist-high, keeping your eyes on the target for accuracy.

Find x and h in this trinomial right angle

Answers

Answer:

Step-by-step explanation:

Set up the Pythagorean Equation for the two triangles

x^2 + h^2 = 4^2  = 16

(x + 6)^2 + h^2 = 8^2 = 64

x^2 +    h^2 = 16                        Subtract. That will get rid of h^2

(x + 6)^2 - x^2 = 64 - 16            Expand the brackets. combine the right.

x^2 + 12x+36 - x^2 = 48           Combine

12x + 36 = 48                            Subtract 36 from both sides

12x +36 -36 = 48-36                 Combine

12x = 12                                      Divide by 12

12x/12 = 12/12

x = 1

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

x^2 + h^2 = 4^2

1^2 + h^2 = 16

h^2 = 15

h = sqrt(15)

A 4-digit number ends in 3. If you put the number 3 in the first position, the number will decrease by 738. Find the original 4-digit number.

Answers

Answer:

4153

Step-by-step explanation:

Given:

A 4-digit number ends in 3

Let the number be xyz3

Also,

If you put the number 3 in the first position, the number will decrease by 738 i.e.

new number 3xyz is 738 less than xyz3

xyz3-

3xyz=738

Now from above we can see that a number z when subtracted from 13(from rule of lending in subtraction as 8 is greater than 3) results in 8,

13-z=8

z=13-8

z=5

Then z-y=3, we have z=5 but from previous calculation 1 is lend to 3 so now z is reduced to 4 hence 4-y=3

y=4-3

y=1

then y-x=7, we have y=1 so when a number x when subtracted from 11(from rule of lending in subtraction as 7 is greater than 1) results in 7,

11-x=7

x=11-7

x=4

hence we have now values of x,y and z putting the values in original number we get

4153

and new number is 3415 then

Now 4153-3415=738 !
