Answer:

5^15

Step-by-step explanation:

Using the laws of powers, you can multiply 5^3 out of its bracket and get 5^27. Then, once again, using the laws of powers, you can get 5^15 by subtracting the powers.

Answer:

(5^3)^9/5^12 is equivalent to 5^15

Step-by-step explanation:

Begin by simplifying (5^3)^9

To make it much easier, apply the power rule. (a^x)^y = a^xy)

Multiply 3 x 9 = 27... so we get 5^27

Next, instead of dividing 27/12, which will result in a decimal..you must do 27-12, which is applying the quotient rule.  (a^x / a^y = a^x-y)

5^27/5^12 = 5^27-12 = 5^15

( When I use /, it signifies to divide.)

So,  (5^3)^9/5^12 is equivalent to 5^15! Hope this helps! :D

The complete square of the given polynomial is

[tex](x+\frac{3}{2})^2=\frac{43}{12}[/tex]

For solving the quadratic equation by completing the square, we first need to ensure that the constant of the square variable is unit.

Following are the steps involved

[tex]5x^2+15x-4=0[/tex]

divide both side by 5

[tex]x^2+3x-\frac{4}{3}=0[/tex]

add 9 on both sides of the equations

[tex]x^2+3x-\frac{4}{3}-9/4+ 9/4=0[/tex]

[tex]x^2+3x+ 9/4=\frac{4}{3}+9/4\\(x+3/2)^2=43/12[/tex]

Therefore we the complete square of the given polynomial is

[tex](x+\frac{3}{2})^2=\frac{43}{12}[/tex]

Answer:

A

Step-by-step explanation:

Answer:

BC ≈ 18.7

Step-by-step explanation:

using the sine rule in Δ ABC

[tex]\frac{BC}{sinA}[/tex] = [tex]\frac{AC}{sinB}[/tex] ( substitute values )

[tex]\frac{BC}{sin67}[/tex] = [tex]\frac{20}{sin80}[/tex] ( cross- multiply )

BC × sin80° = 20 × sin67° ( divide both sides by sin80° )

BC = [tex]\frac{20sin67}{sin80}[/tex] ≈ 18.7 ( to the nearest tenth )

Answer:

28

Step-by-step explanation:

4 x 77 / 11 x 1  =  308 / 11

308/11 = 28    11/11 = 1

the answer is 28 / 1

Hey there!

4/11 of 77

= 4/11 * 77/1

= 4(77) / 11(1)

= 77(4) / 1(11)

= 77 + 77 + 77 + 77 / 11

= 154 + 154 / 11

= 308 / 11

= 28

Therefore, your answer is: 28

The faces of pyramids are triangles.

The faces of prisms are rectangles.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The number of vertices is always equal to the number of sides for a prism but not a pyramid.

The faces of pyramids are triangles while the faces of prisms are rectangles.

A prism has two parallel bases and its other faces are rectangles.

A pyramid has a single base and its faces are triangles.

A prism also has the same number of vertices as its number of sides, but this is not true for a pyramid.

Thus,

The difference between a pyramid and a prism is:

There is only one base for a pyramid.

The faces of pyramids are triangles.

The faces of prisms are rectangles.

6=-2p+10/5

x5 to both sides to get rid of denominator

30=-2p+10

-10 from both sides to get rid of it on the right

Answer:

sqrt2/sqrt3; 1/sqrt3; sqrt5/2

Step-by-step explanation:

to solve this equation you can basically put paranthesis squared around all of the options

(sqrt2/sqrt3)^2 becomes simply 2/3

(1/sqrt3)^2 becomes simply 1/3

(pi/3)^2 becomes a decimal that is not rational

[(sqrt5)/2]^2 becomes simply 5/4

the first, second, anad last are all rational

The value of the x of the equation x² + 2x = 24 is negative 5 and negative 1, then the correct option is A.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression equation is given below.

f(x) = x² + 6x + 5

On factorization, we have

     x² + 6x + 5 = 0

x² + 5x + x + 5 = 0

   (x + 5)(x + 1) =0                    

                    x = -1, -5

The value of x is –5 and –1.

Answer:C. 38.14

Step-by-step explanation:

The required mean of the given data is given as the employee worked 38.14 hours through 7 weeks.

Given that,
The number of hours the employee worked each week for seven consecutive weeks was 38, 37. 5, 38. 25, 35. 75, 39. 5, 39. 5, and 38. 5.

The mean of the values is the ratio of the total sum of values to the number of values.

here,
According to the question,
Mean = Sum of the working hours/number of weeks
Mean = 38 + 37. 5 + 38. 25 + 35. 75 + 39. 5 + 39. 5 + 38. 5 / 7
Mean = 267/7
Mean = 38.14

Heating and Cooling Degree Days

Degree days are based on the assumption that when the outside temperature is 65°F, we don't need heating or cooling to be comfortable. Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. If the temperature mean is above 65°F, we subtract 65 from the mean and the result is Cooling Degree Days. If the temperature mean is below 65°F, we subtract the mean from 65 and the result is Heating Degree Days.

Step-by-step explanation: Example 1: The high temperature for a particular day was 90°F and the low temperature was 66°F. The temperature mean for that day was:

( 90°F + 66°F ) / 2 = 78°F

Because the result is above 65°F:

78°F - 65°F = 13 Cooling Degree Days

Example 2: The high temperature for a particular day was 33°F and the low temperature was 25°F. The temperature mean for that day was:

( 33°F + 25°F ) / 2 = 29°F

Because the result is below 65°F:

65°F - 29°F = 36 Heating Degree Days.

The calculations shown in the two examples above are performed for each day of the year and the daily degree days are accumulated so that we can compare months and seasons.
