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:

f=41, 41×(-8)=-328(not so sure so you might want so check with other people again)

Step-by-step explanation:

f(x)=12x-29

Step 1, u bring the x terms over to one side, in this case on the left side. So it becomes:

f(x)-12x=29

Next step is to find the common factor of the x terms

f(x)-12(x)=29

f-12=29

bring the numbers to the right side

f=29+12

so f=41

Answer:

2000 ml

Step-by-step explanation:

Given: Sarai pours all the liquid from a full small beaker into a  larger beaker.

           The liquid fills the large beaker to 15% of its capacity.

            The small beaker holds 300 ml.

Lets assume capacity of large beaker to hold be "x".

As given, Sarai pours all the liquid from a full small beaker into a larger beaker

∴ [tex]15\% \times x= 300\ ml[/tex]

⇒ [tex]0.15x= 300[/tex]

Dividing both side by 0.15

⇒[tex]x= \frac{300}{0.15}[/tex]

∴ [tex]x= 2000\ ml[/tex]

Hence, the large beaker can hold 2000 ml of liquid.

Step-by-step explanation:

If suffices to look at the last term. It must simplify to 4/(3w²), so the exponents of z must match in numerator and denominator, and the ratio of constants must reduce to 4/3.

The exponents of z have the right values in choices B and D, but the ratio of constants only matches in choice D. Looking at the rest of choice D, we see that we can factor 6w²z² from both numerator and denominator, then factor 2 from the remaining numerator to make it match the desired form.

Answer:

2294.20

Step-by-step explanation:

the formula [tex]A = P (1+\frac{r}{n}) ^{nt}[/tex] will show the exponential growth in the account

A = amount in account (how much you'll have after earning interest)

P = the initial amount (how much YOU put in the account)

r = interest rate (in decimal form)

n = the number of times the interests in compounded in one year

t = number of years

plug in numbers into formula

(4.2 will become 0.042 because we need it as a decimal)

(n = 12 because monthly means every month and there is 12 months in a year)

formula will look like [tex]A = 2200 (1+\frac{0.042}{12})^{12(1)}[/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.

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: 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].

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]

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)
