Answer 1

Answer:

[tex] \huge{ \boxed{ \sf{ \frac{1}{64} }}}[/tex]

Step-by-step explanation:

[tex] \star{ \sf{ \: \: \: {4}^{ - \frac{11}{3} } \div {4}^{ - \frac{2}{3} } }}[/tex]

[tex] \underline{ \: \text{Remember!}} : [/tex] If [tex] \sf{ {x}^{a} \: and \: {x}^{b} }[/tex] are two algebraic terms , then their quotient is given by [tex] \sf{ {x}^{a} \div {x}^{b} = {x}^{a - b} } [/tex]

i.e To divide two terms with the same base, the power of divide is subtracted from the power of the dividend and the same base is taken.

[tex] \mapsto{ \sf{ {4}^{ - \frac{11}{3} - ( - \frac{2}{ 3}) } }}[/tex]

[tex] \sf{We \: know \: that : ( - ) \times ( - ) = ( + )}[/tex]

[tex] \mapsto{ \sf{ {4}^{ - \frac{11}{3} + \frac{2}{3} } }}[/tex]

Now, Simplify : -11/3 and 2/3

While performing the addition or subtraction of like fraction, you just have to add or subtract the numerator respectively in which the denominator is retained same.

[tex] \mapsto{ \sf{ {4}^{ \frac{ - 11 + 2}{3} } }}[/tex]

[tex] \underline{ \text{Remember!}} : [/tex] The negative and positive integers are always subtracted but posses the sign of the bigger integer

[tex] \mapsto{ \sf{ {4}^{ \frac{ - 9}{3} } }}[/tex]

Divide -9 by 3

[tex] \mapsto{ \sf{ {4}^{ - 3} }}[/tex]

[tex] \underline{ \text{Remember!}} : [/tex] If [tex] \sf{ {a}^{ - m}} [/tex] is an algebraic term , where m is a negative integer , then

[tex] \sf{ {a}^{ - m} = \frac{1}{ {a}^{m} } }[/tex]

[tex] \mapsto{ \sf{ \frac{1}{ {4}^{3} } }}[/tex]

Evaluate the power : 4³

[tex] \mapsto{ \sf{ \frac{1}{64} }}[/tex]

Hope I helped!

Best regards!:D

What is rounding for math

Answers

Answer:

Step-by-step explanation:

Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. But 76 goes up to 80. There are many ways to round.

Hey there!

Rounding is estimating a number to its closest value. Let's say for example the number 226. If you round 226 to the nearest ten, you would get 230. This is what rounding is.

Hope this helps!

Angela is shopping for pet supplies and needs to buy a kennel and several toys. At Paws R Us, she would pay $50.75 for the kennel and $3.75 for each pet toy. At Truth or Tail, she would pay $43.25 for the kennel and $5 for each pet toy. Write an inequality to represent t, the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option.​

Answers

Answer: t>6

Step-by-step explanation:

Amount to pay = Cost of kennel + (Cost per toy )x (Number of toys)

Let t = the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option.​

Given, At Paws R Us, she would pay $50.75 for the kennel and $3.75 for each pet toy.

Amount to pay =  $(50.75 + 3.75t)

At Truth or Tail, she would pay $43.25 for the kennel and $5 for each pet toy.

Amount to pay =  $(43.25 + 5t)

According to the question , we have

50.75 + 3.75t < 43.25 + 5t

Subtract 3.75t from both sides

50.75+ 3.75t -3.75t   < 43.25 + 5t -3.75t

⇒ 50.75< 43.25 +1.25 t

Subtract  43.25 from both sides, we get

50.75 - 43.25 < 1.25 t

⇒  7.5< 1.25 t

Divide both sides by 1.25 we get

⇒   6<t

Hence, the required inequality to represent t, the number of pet toys Angela would need to buy for Paws R Us to be the cheaper option:

[tex]t>6[/tex] .

F(x) = x^3 (a) computer f(x)dx (b) computer the approximation L, and T, for n=4, 8, and 16 for the integral in part (a). For each of these, compute the corresponding absolute error.

Answers

Answer and Step-by-step explanation:

F(x) = x^3 (a)

then

compute f(x) dx for each of these, compute the corresponding absolute error.

Solution:  f(x) = x3

            F(x) d(x) = 3x2

The absolute error are ∆x= |x-ẋ|, ∆f=|f(x) – f(ẋ)|

(b) Compute the approximation L, and T, for n=4, 8, and 16 for an integral part.

The linear (L) approximation of function f(x) = x3, n= 4

  f(4) = (4)3 = 64 and f”(4) = 3(4)2 = 48

The linear approximation is  L4(x) = f (4) + f’(4)(x-4)

                       

                           = 64 + 48 (x-4)

For n= 8,

  f(8) = 512 and f,(8)= 3(8)2= 192

The linear approximate is L8(x) = f(8) + f’(8)(x-8)

Similarly for n= 16 the linear approximate is L16(x) = f (16) + f (16) (x-16)

The approximation for T, trapezoidal rule is:

a ʃb f(x)dx = Tn

for n = 4 the T approximation is:

T4  =a ʃb  x3 dx

For n= 8 :

T8 = a ʃb x3 dx

For n= 16 : T16= a ʃb x3 dx.

Answers

Answer:

Option B

Step-by-step explanation:

The two samples are paired as the gas mileage of 48 trucks is measured for before tuneup and after tuneup. The gas mileage of 48 trucks will be affected by receiving tuneup. As the same 48 trucks are selected for tuneup, so the sample will be dependent. Hence the two samples are dependent because the same trucks are sampled.

Hey are you good at algebra

What is the mean what is the mean for 35, 40, 12, 16, 25, 10

Answers

Answer:

Mean=23

Step-by-step explanation:

Mean = Sum of all values/ total no of values

There are six numbers .

Mean =

[tex]\frac{35+40+12+16+25+10}{6} \\\\= \frac{138}{6} \\\\=23[/tex]

Answer:

[tex]\boxed {\tt 23}[/tex]

Step-by-step explanation:

The mean can be found by adding all the values together and dividing by the number of values.

1. Add the values

The values are: 35, 40, 12, 16, 25, 10 Add them: 35+40+12+16+25+10=138

2. Divide by the number of values

Count how many numbers are in the set of data. There are 6 values. Divide 138 by 6.

138/6=23

The mean of the data set is 23.


Gavin, Colin and Dan share some sweets in the ratio 2:4:3. Gavin gets 24 sweets
How many more sweets does Colin get over Dan?

Answers

Answer:

12

Step-by-step explanation:

[tex]G:C:D\\----\\2:4:3[/tex]

Gavin has 24 sweets which is 2 units.

2 units = 24 sweets

1 unit = [tex]24\ sweets \div 2 = 12\ sweets[/tex]

Colin has 4 units, while Dan has 3 units.

Colin has 1 unit more than Dan.

Since 1 unit is 12 sweets, Colin has 12 more sweets than Dan.

How do you do this question?

Answers

Step-by-step explanation:

f(x) = 38 cos(x²)

Use chain rule to take the derivative.

f'(x) = -38 sin(x²) (2x)

f'(x) = -76x sin(x²)

Use product rule and chain rule to take the derivative.

f"(x) = -76x cos(x²) (2x) + (-76) sin(x²)

f"(x) = -152x² cos(x²) − 76 sin(x²)
