Answer:

-8x(8yz)(-8)

Step-by-step explanation:

(-2x^2yz^-2)4

-8x(8yz)(-8)

Answer:

- 3

Step-by-step explanation:

Given

7 - 2h ( substitute h = 5 into the expression )

= 7 - 2(5)

= 7 - 10

= - 3

On evaluating the function at h = 5, we get -

f(5) = - 3.

We have a function -

f(h) = 7 - 2h

We have to find the value of f(h) at h = 5.

f(x) = Sin( [tex]\frac{\pi }{x}[/tex] )

f(2) = Sin( [tex]\frac{\pi }{2}[/tex] )

f(2) = 1

According to the question, we have -

f(h) = 7−2ℎ

Now, evaluating the function at h = 5, we get -

f(5) = 7 - 2 x 5 = -3

Hence, on evaluating the function at h = 5, we get -

f(5) = - 3.

#SPJ2

Answer:

Step-by-step explanation:

We need to find the LCM of 12 and 9.

Their LCM is:

Number of light fixtures and light bulbs is 36.

Number of packages will be:

Step-by-step explanation:

First finding LCM of 9 and 12

9 = 3 × 3

12 = 2 × 2 × 3

LCM = 3 × 2 × 2 × 3

LCM = 36

Now,

No. of light fixtures = 36/12 = 3

No. of light bulb = 48/12 = 4

Answer:

y = -3/4x + 14

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal of the original line.

4/3x -> -3/4x

Now we need to find the y-intercept and we can do that by using the slope intercept form expression [ y = mx + b ].

11 = -3/4(4) + b

11 = -3 + b

14 = b

Put everything we know and solved for back into the expression.

y = -3/4x + 14

Answer:

[tex] {4a}^{4} \times {7a}^{5} \\ \\ = (4 \times 7)( {a}^{4} \times {a}^{5} ) \\ \\ = 28( {a}^{4} \times {a}^{5} )[/tex]

from law of indices:

[tex] {n}^{x} \times {n}^{y} = {n}^{(x + y)} [/tex]

therefore:

[tex] = 28 \{ {a}^{(4 + 5)} \} \\ \\ = 28 {a}^{9} [/tex]

Answer:

28a^9

Step-by-step explanation:

Answer:

x = 1/2

Step by step explanation:

Two numbers a and b are each greater than zero.

i.e a > 0 and b > 0

And;

[tex] \sqrt{a} \: = \: \sqrt[3]{b} [/tex]

Since the square root of a is equal to cube root of b then,

a = b = 1

[tex] {a}^{2x \: - \: 1} \: = \: b[/tex]

[tex] {1}^{2x \: - \: 1} = {1}^{0} [/tex]

2x - 1 = 0

x = 1/2

Two numbers are 'a' and 'b'.

And a > 0, b > 0

[tex]\sqrt{a}=\sqrt[3]{b}[/tex]

[tex]a^{\frac{1}{2} }=b^{\frac{1}{3}}[/tex]

[tex]a=(b)^{\frac{2}{3} }[/tex]

We have to find the value of [tex]x[/tex] if [tex]a^{2x-1}=b[/tex],

By substituting the value of [tex]a[/tex] in the given expression,

[tex](b^{\frac{2}{3}})^{2x-1}=b[/tex]

Now use the laws of exponents,

[tex]b^{\frac{2}{3}(2x-1)}=b[/tex] [Since, [tex](a^m)^n= a^{mn}[/tex]]

By comparing the exponents on both the sides,

[tex]\frac{2}{3}(2x-1)=1[/tex]

[tex]2(2x-1)=3[/tex]

[tex]4x-2=3[/tex]

[tex]4x=5[/tex]

[tex]x=\frac{5}{4}[/tex]

[tex]x=1.25[/tex]

Answer:

  27

Step-by-step explanation:

Evaluating this expression according to the order of operations is a straightforward calculator problem.

  = (81 ÷ 27)³ = 3³ = 27

__

You can also use the rules of exponents to simplify this before evaluating.

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

__

  = ((3²)² ÷ 3³)³ = (3⁴ ÷ 3³)³ = (3¹)³ = 3³ = 27

We have that  The Total Number of People is

[tex]X\approx 137[/tex]

From the question we are told that

sample of 200

income is $48,000 per year

standard deviation of $9000

Generally the equation for the Ratio of people  is mathematically given as

[tex]Y=P(\frac{39000-48000}{9000}<z<\frac{57000-48000}{9000})\\\\\Y=P(z<1))-(1-p(z-1))\\\\Y=0.8413-0.1582\\\\\Y=0.6826[/tex]
