How do you express eight less than a number squared?

Answer:

The number 1 is not necessary when expressing powers of one. For example, you needn't write "5" as [tex]5^{1}[/tex].

Step-by-step explanation:

The number 1 is written when it is part of a larger number, as it is significant. It is not necessary to write leading zeros. In scientific notation, trailing zeros are excluded, and the number is written in a form where only non-zero digits appear before the decimal.

Understanding when to write the number 1 and when it's not needed depends on the context in mathematics, especially when dealing with significant figures and scientific notation. Generally, all non-zero numbers are considered significant (rule 1), which means that when a value like 1 is part of a larger number, it contributes to the meaning of that number. However, leading zeros do not count as significant (rule 3).

In the case of multiplication by units, like converting from kilograms to grams, we utilize the concept of multiplying by the number 1 to affect the units without changing the value. For example 0.7 kg can be multiplied by 1000/1 (1000 g / 1 kg) to convert to grams. This is because 1000/1 is equal to 1000, indicating multiplication by one does not change the value.

When expressing numbers in scientific notation, it's important to include the non-zero digits only before the decimal point, excluding any trailing zeros. Thus, 1,500,000 would be written as 1.5 x 106, with the power indicating the necessary number of decimal point movements to place it after the first significant digit.

Answer:

3.68

Step-by-step explanation:

The proportion that could be used to solve for the variable is:

[tex]\frac{16}{40} = \frac{3}{h}[/tex]

h = 7.5

Solution:

Given that,

16 walls in 40 hours 3 walls in h hours

Which means,

16 walls build in 40 hours

Then 3 walls in h hours

We have to write a proportion

The number of walls and the number of hours are proportion

Therefore, we get,

[tex]\frac{16}{40} = \frac{3}{h}[/tex]

Cross multiply and solve for h

[tex]16 \times h = 3 \times 40\\\\16h = 120\\\\h = \frac{120}{16}\\\\h = 7.5[/tex]

Thus the proportion is solved

Answer:

(-2,-4),(2,1), and (7,-5)

Step-by-step explanation:

The given triangle has coordinates (6,4), (2,-1), and (-3,5).

When we translate 4 units left, the we obtain:

(6,4)------>(6-4,4)=(2,4)

(2,-1)----->(2-4,-1)=(-2,-1)

(-3,5)----->(-3-4,5)=(-7,5)

When the resulting figure is rotated 180° about the origin, the coordinates of the final figure becomes

(2,4)------>(-2,-4)

(-2,-1)----->(2,1)

(-7,5)------->(7,-5)

NB: The mapping for 180° rotation is:

(x,y)----->(-x,-y)

The graph of the function starts high and ends high.

Answer: Option B.

Explanation:

The end conduct of a graph is characterized as what is happening at the parts of the bargains. As the capacity approaches positive or negative infinity, the main term figures out what the diagram resembles as it moves towards vastness.

The end conduct of a chart is the way our capacity carries on for extremely huge and tiny info esteems. For exponential capacities, we see that our end conduct goes to endlessness as our information esteems get bigger. The bigger the base of our exponential capacity, the quicker the development.

The end behavior of the function F(x) = 2x^4 + x^3 is determined by the term 2x^4. As x tends toward both positive and negative infinity, this term causes the function to increase towards infinity, meaning the graph starts low and ends high.

The question asks about the end behavior of the polynomial function F(x) = 2x^4 + x^3. To determine this, we look at the highest degree term, which dominates the end behavior. In this case, that term is 2x^4.

As x approaches positive infinity, 2x^4 will grow very large, so the function will also go towards infinity. Similarly, as x approaches negative infinity, 2x^4 will still grow very large (since an even power of a negative number is positive), and the function will go towards infinity as well. Thus, the graph of the function starts low when x is very negative and ends high as x becomes very positive.

Therefore, the correct answer to the student's question is Option A: The graph of the function starts low and ends high.

Step-by-step explanation:

Old rectangular monitor screen:

Width = x in

Length = x + 4 in

Area [tex]=x(x+4)\ in^2[/tex]

New rectangular monitor screen:

Width = x - 1 in

Length = 2(x + 4) in

Area [tex]=(x-1)(2(x+4))=2(x-1)(x+4)\ in^2[/tex]

This area would be increased by [tex]216\ in^2,[/tex] so the area would be equal to [tex]x(x+4)+216\ in^2[/tex]. Hence,

[tex]2(x-1)(x+4)=x(x+4)+216\\ \\2(x^2+4x-x-4)=x^2+4x+216\\ \\2x^2+6x-8-x^2-4x-216=0\\ \\x^2+2x-224=0\\ \\D=2^2-4\cdot (-224)=4+896=900\\ \\x_{1,2}=\dfrac{-2\pm \sqrt{900}}{2}=\dfrac{-2\pm 30}{2}=-16,\ 14[/tex]

The width cannot be negative, so

Width = 14 in

Length = 14 + 4 = 18 in

Final answer:

To write an algebraic expression in terms of k, subtract the number of kittens given away from the initial number of kittens. The algebraic expression in terms of k is (3/5)x.

Explanation:

To write an algebraic expression in terms of k, we need to determine the initial number of kittens before any were given away. Let's call this number 'x'. According to the problem, 2/5 of the kittens were given away. This means that (2/5)x kittens were given away, leaving k kittens remaining.

To find the algebraic expression in terms of k, we subtract the number of kittens given away from the initial number of kittens. So the expression is x - (2/5)x = k.

We can simplify this expression by finding a common denominator for the fractions. In this case, the common denominator is 5. So the expression becomes 5x/5 - (2/5)x = k. Simplifying further, we have (3/5)x = k. Therefore, the algebraic expression in terms of k is (3/5)x.

Answer:

Similar polygon

Step-by-step explanation:

To find the length of the missing side, you can use the Pythagorean Theorem, which you can only use for right triangles.

Pythagorean Theorem:  a² + b² = c²

[ c is the hypotenuse or the longest side of the triangle, and a and b are the other sides, I think it doesn't matter which side ]

Plug in what you know:

b = 8

c = 14

a² + b² = c²

a² + (8)² = (14)²

a² + 64 = 196       Subtract 64 on both sides

a² = 132       Square root both sides to get "a" by itself

[tex]\sqrt{a^2} =\sqrt{132}[/tex]

a = [tex]\sqrt{132}[/tex] inches

If you need to simplify more, you need to find two numbers that multiply to = 132 where one of them can be square rooted, to do so you can list the greatest common factors of 132

132: 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132

The only number that can be square rooted is 4, so you can do:

[tex]a=\sqrt{4*33}[/tex]

[tex]a=\sqrt{4} *\sqrt{33}[/tex]

[tex]a=2\sqrt{33}[/tex]

Answer:

Step-by-step explanation:

To find the length of LK, we can use the triangle similarity concept. First, let's compare triangles LJK and LMK. We can see that they share angle L, and we know that LJ = 10 and KM = 7. By comparing the corresponding sides, we can set up the proportion: LK / LJ = KM / KJ Substituting the given values, we have: LK / 10 = 7 / 11 To solve for LK, we can cross multiply and then divide: LK * 11 = 10 * 7 LK * 11 = 70 LK = 70 / 11 So, LK = 6.36 (rounded to two decimal places). Therefore, the answer is not provided in the answer choices.

From the answer choices, we can conclude that LK = d. 70/11.

From the figure we are given, we can use the property of corresponding angles to determine the probable value of LK. From the corresponding sides, LK/LJ is equal to KM/KJ. Now, we substitute the given values to have the following:

LK / 10 = 7 / 11

To get the exact value of LK, we cross-multiply as follows:

LK * 11 = 10 * 7

LK * 11 = 70

LK = 70 / 11

So, the value of LK = 70/11.

Answer: Answer is x = 5, y = -3

(5, -3)

Step-by-step explanation: The instruction is to use the substitution method, and from the first equation,

y = x - 8

This means we replace the value of y in the second equation with x - 8. Hence;

2x + 3y = 1 can now be re-written as

2x + 3(x - 8) = 1

2x + 3x - 24) = 1

5x - 24 = 1

Add 24 to both sides of the equation

5x -24 + 24 = 1 + 24

5x = 25

Divide both sides of the equation by 5

x = 5

Having calculated x as 5, we can now substitute for the value of x in the first equation

y = x - 8 now becomes

y = 5 -8

y = -3

Using the substitution method, we found the solution to be (5, -3), which matches option a.

To solve the system of equations using the substitution method, we'll first solve one equation for one variable and then substitute it into the other equation.

Given:

1. [tex]\( y = x - 8 \)[/tex] (Equation 1)

2. [tex]\( 2x + 3y = 1 \)[/tex] (Equation 2)

From Equation 1, we can solve for y:

[tex]\[ y = x - 8 \][/tex]

[tex]\[ x = y + 8 \][/tex] (Re-arranging)

Now, substitute [tex]\( x = y + 8 \)[/tex] into Equation 2:

[tex]\[ 2(y + 8) + 3y = 1 \][/tex]

Simplify and solve for y:

[tex]\[ 2y + 16 + 3y = 1 \][/tex]

[tex]\[ 5y + 16 = 1 \][/tex]

[tex]\[ 5y = 1 - 16 \][/tex]

[tex]\[ 5y = -15 \][/tex]

[tex]\[ y = -3 \][/tex]

Now, substitute [tex]\( y = -3 \)[/tex] into Equation 1 to find [tex]\( x \)[/tex]:

[tex]\[ x = (-3) + 8 \][/tex]

[tex]\[ x = 5 \][/tex]

So, the solution to the system of equations is [tex]\( (x, y) = (5, -3) \)[/tex].
