Step-by-step explanation:

9000 + 300 + 100 * 6 / 800

According to Order Of Operations, we multiply and divide first.

9000 + 300 + 600 / 800

Divide.

9000 + 300 + 0.75

Add.

9300 + 0.75

Add.

9300.75.

Answer:

9,000+300+100×6÷800=9,300.75

pls mark me brainless

Answer:

a)  f(g(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x

    g(f(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x

    f and g are inverses

b)   f(g(x)) = x + 3 + 3 = x + 6

     g(f(x)) = x + 3 + 3 = x + 6

     f and g are not inverses

Step-by-step explanation:

a)

f(g(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x

g(f(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x

Since f(g(x)) = g(f(x)) = x, then f and g are inverses

b)

f(g(x)) = x + 3 + 3 = x + 6

g(f(x)) = x + 3 + 3 = x + 6

Since f(g(x)) = g(f(x)) ≠ x, then f and g are not inverses

Answer:

To transform the given expression to the sum of cubes, calculate first the cube root of the terms. The cube root of the first term, 64x^6 is 4x^2 and that of the second term, 27 is 3.

Thus, the answer to this is (4x^2)^3 + 3^3

Answer:

The value of a₂₇ is 788

Step-by-step explanation:

a₁₉ = 548

a₃₃ = 968

Now,

a₁₉ = 548 can be written as

a + 18d = 548 ...(1) and

a₃₃ = 968 can be written as

a + 32d = 968 ...(2)

Now, from equation (2) we get,

a + 32d = 968

a + 18d + 14d = 968

548 + 14d = 968 (.°. a + 18d = 548)

14d = 968 - 548

14d = 420

d = 420 ÷ 14

d = 30

Now, for the value of a put the value of d = 30 in equation (1)

a + 18d = 548

a + 18(30) = 548

a + 540 = 548

a = 548 - 540

a = 8

Now, For a₂₇

a₂₇ = a + 26d

a₂₇ = 8 + 26(30)

a₂₇ = 8 + 780

a₂₇ = 788

Thus, The value of a₂₇ is 788

Step-by-step explanation:

Step-by-step explanation:

height= 4b

length = 2 + b

volume = 60in³

or, l ×b × h = 60in³

or, (2+b) × b × 4b = 60in³

or, 4b²(2+b) = 60in³

or, 8b² + 4b³ = 60

or, 2b² + b³ = 15

or, b³ + 2b² -15= 0

b= 1.95

l= 2+1.95=3.95

h= 4×1.95 = 7.8

Answer:

[tex]a_{8} = 15[/tex]

Step-by-step explanation:

[tex]a_{1} + a_{2} + ..... + a_{7} + a_{8} = 8^{2} = 64[/tex]

[tex]-a_{1} - a_{2} ..... - a_{7} = - 7^{2} = -49[/tex]    Now add the two equations

                                 [tex]a_{8} = 64 - 49 = 15[/tex]

Answer:

9

Step-by-step explanation:

Iḿ pretty sure it is 9 because its mostly in the center the other numbers

The best measure of the center of the data is 9.

The mean is the mathematical average of a set of two or more numbers.

The median is the middle value in a list ordered from smallest to largest.

[tex]median= [\frac{(\frac{n}{2} )^{th} term+((\frac{n}{2} +1) )^{th} term}{2} ][/tex]        (for even number of observation)

[tex]median= [\frac{(n+1)^{th} term}{2} ][/tex]                            ( for odd number of observation)

The mode is the value that appears most frequently in the data set.

According to the given question

we have

A data , 10, 7, 9, 11, 8

Number of observation, n = 5   (which is odd)

Arranging the above data in ascending order

7,8,9,10,11

For calculating the median of the data ,substitute value of n in the formula of median for odd number of observation

therefore,

median = (5+1)th term/2

median = 6/2

median =  3rd term i.e. 9

The best measure of the center of this data is 9.

Answer:

[tex]y\leq 4[/tex]

Step-by-step explanation:

The range is about the y values, and by looking at this parabola we can see that the maximum value is a 4. So the range would be the maximum and below (where the parabola extends to). So the values in the range would be equal to 4 and less than since the parabola is negative.
