given h(×)=×^2-2 find the value of h(-3)

The equation of the function shown in the graph is f(x) = log₂(x + 4) - 1

How to determine the equation of the function shown in the graph

From the question, we have the following parameters that can be used in our computation:

The graph

Where, we have

g(x) = log₂(x)

First, the function is shifted to the left by 4 units

So, we have

g(x) = log₂(x + 4)

Next, the function is shifted down by 1 unit

So, we have

f(x) = log₂(x + 4) - 1

Hence, the equation of the function shown in the graph is f(x) = log₂(x + 4) - 1

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 !

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

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.

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.

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.

18 x 3/8 = Answer

if the bucket is only 3/8 full when holding 18 liters then it is 1/8 full when holding 6 liters. so just multiply 6 by 8 and you get 48 liters

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.

The fabric required to make the model tent should be 144 squared inches.

When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.”

As the shape of tent is is triangular prism.

As the fabric needed to make the model tent is in square inches.

So, the number should be a perfect square of any number to make the tent.

The equation is [tex]8x^2 -6x+1=0[/tex]

Step-by-step explanation:

We need to find the quadratic equation which is in the form:

[tex]ax^2 + bx + c = 0[/tex]

We are given sum S = 3/4 and Product P = 1/8

The quadratic equation in terms of sum and products can be written as:

[tex]x^2 - Sx + P =0[/tex]

Where S is sum and P is product. Putting their values we get:

[tex]x^2-\frac{3}{4}x+\frac{1}{8}=0[/tex]

The co-efficient should be integer so, taking LCM of 4 and 8

[tex]\frac{8x^2 -6x+1}{8} =0\\Dividing\,\,both\,\,sides\,\,by\,\,8\\8x^2 -6x+1=0[/tex]

So,

Co-efficient are:  a = 8 , b = -6 and c= 1

Solving the equation:

[tex]8x^2 -6x+1=0\\8x^2 -2x -4x+1=0\\8x(x-1/4)-4(x-1/4) =0\\(x-1/4)(8x-4)=0\\x-1/4 =0\,\, and\,\, 8x-4 =0\\x = 1/4\,\, and x \,\,= 4/8 = 1/2[/tex]

So values of x are 1/4 and 1/2

Answer:

option C Only second equation is an identity is correct.

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:

[tex]cot\theta = \frac{cos\theta}{sin\theta} \\and \\sec\theta=\frac{1}{cos\theta} \\so,\,\, \frac{cot\theta}{sec\theta}= \frac{\frac{cos\theta}{sin\theta}}{\frac{1}{cos\theta}}  \\Solving\\ \frac{cot\theta}{sec\theta} =\frac{cos^2\theta}{sin\theta}[/tex]

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]
