Answer:

Step-by-step explanation:

It might be helpful to think of the % symbol as being interchangeable with /100.

133 1/2% = (133 1/2)/100 = 267/200 = 1.335

87 1/3% = (87 1/3)/100 = 262/300 = 131/150 = 0.8733333... (repeating 3)

0.01% = 0.01/100 = 1/10000 = 0.0001

8 1/3% = (8 1/3)/100 = 25/300 = 1/12 = 0.0833333... (repeating 3)

Answer:

  1.05 × 1.05 × 1.05 × 1.05 × 1.05 = 1.2762815625

Step-by-step explanation:

An exponent indicates how many times the base is a factor in the product. That is, 1.05 to the 5th power means ...

  1.05⁵ = 1.05 × 1.05 × 1.05 × 1.05 × 1.05

This multiplication expression is evaluated in the usual way.

  = 1.1025 × 1.05 × 1.05 × 1.05

  = 1.157625 × 1.05 × 1.05

  = 1.21550625 × 1.05

  = 1.2762815625

All scientific and graphing calculators have a button for computing the power of a number. On my calculator its label is [tex]\displaystyle \boxed{y^x}[/tex]. The particulars of the function of this button can be found in the manual for your calculator.

For on-line calculators, such as the go.ogle calculator, or the Desmos graphing calculator, the caret (^) is used to signify an exponent. (See the input line in the first attachment for an example.)

Answer: 1/30

Step-by-step explanation:

Answer:

As a plumber charges a customer a one-time service fee of $ 79, $ 62 per hour for labor, and a surcharge of $ 15 per hour due to the call being an emergency, to write an expression to represent the total charges for the plumber in two different ways, with H representing the number of hours the job takes, the following equations should be formulated:

Option 1:

Fixed amount + amount per hour multiplied by the number of hours + emergency amount multiplied by the number of hours = X

79 + 62H + 15H = X

Option 2:

Fixed amount + sum of emergency amount and the amount per hour multiplied by the number of hours = X

79 + ((62 + 15) x H) = X

Answer:

x = 1.91

Step-by-step explanation:

x + 6.62 = 8.53

x + 6.62 - 6.62 = 8.53 - 6.62

x = 1.91

This question is incomplete, the complete question is;

Suppose that a random sample of eighteen recently sold houses in a certain city has a mean sales price of $280,000, with a standard deviation of $10,000. Under the assumption that house prices are normally distributed, find a 95% confidence interval for the mean sales price of all houses in this community. Then find the lower limit and upper limit of the confidence interval.

Answer:

At 95%, confidence interval is ( 275026.7, 284973.3 )

Hence;

Lower limit = 275026.7

Upper limit = 284973.3

Step-by-step explanation:

 Given that;

mean x = $280,000

standard deviation σ = $10,000

sample size n = 18

degree of freedom df = n - 1 = 18 - 1 = 17

∝ = 1 - 95% = 1 - 0.95 = 0.05  

so

Critical t value = tinv( 0.05, 17 ) = 2.11

now, at 95% confidence interval for mean will be;

⇒ x ± [ Critical t value × ( σ/√n) ]

so we substitute

⇒ 280,000 ± [  2.11 × ( 10000/√18) ]

⇒ 280,000 ± [  2.11 × 2357.0226 ]

⇒ 280,000 ± 4973.3

⇒ 280000 - 4973.3, 280000 + 4973.3

At 95%, confidence interval is ( 275026.7, 284973.3 )

Hence;

Lower limit = 275026.7

Upper limit = 284973.3

Answer:

i2 - 9

-85

Step-by-step explanation:

Conjugate of an expression is gotten by simply changing the sign to the opposite sign. For example, the conjugate of 5 is -5, the conjugate of x+2 is x-2. Given the complex value 2i+9, the conjugate will be -85

Taking their product

(2i+9)(2i-9)

Expand

2i(2i)-9(2i)+9(2i)+9(-9)

=  4i²-18-+18i-81

= 4i² - 81

Since i² = -1

= 4(-1) - 81

= -4-81

= -85

Hence the product will give -85

Given:

The figure of triangle GHI and a circle M inscribed in the triangle.

To find:

The perimeter of the triangle.

Solution:

We know that the lengths of the tangent on a circle from same exterior point are always equal.

[tex]JH=HK[/tex]             (Tangent from point H)

[tex]6x-11=2x+9[/tex]

[tex]6x-2x=11+9[/tex]

[tex]4x=20[/tex]

Divide both sides by 4.

[tex]x=\dfrac{20}{4}[/tex]

[tex]x=5[/tex]

Now,

[tex]JH=6x-11[/tex]

[tex]JH=6(5)-11[/tex]

[tex]JH=30-11[/tex]

[tex]JH=19[/tex]

In the same way,

[tex]GJ=GL[/tex]             (Tangent from point H)

[tex]IK=IL[/tex]             (Tangent from point H)

From the figure, it is clear that,

[tex]IL=GI-GL[/tex]

[tex]IL=40-GJ[/tex]

[tex]IL=40-23[/tex]

[tex]IL=17[/tex]

The perimeter of the triangle GHI is:

[tex]Perimeter=GH+HI+GI[/tex]

[tex]Perimeter=(GJ+HJ)+(HK+IK)+(GL+IL)[/tex]

[tex]Perimeter=(23+19)+(19+17)+(23+17)[/tex]

[tex]Perimeter=118[/tex]

Therefore, the perimeter of the triangle GHI is 118 units.

Answer:

x = 7

Step-by-step explanation:

Based on the angle bisector theorem, we would have the following equation:

21/(3x - 12) = 14/6

21/(3x - 12) = 7/3

Cross multiply

(3x - 12)*7 = 3*21

21x - 84 = 63

21x - 84 + 84 = 63 + 84

21x = 147

21x/21 = 147/21

x = 7

Answer:

  g(x) = x + 1

Step-by-step explanation:

The transformation "shift left 3 units" is accomplished by replacing x in the function definition by x+3.

F(x) is defined as ...

  f(x) = 2x -4

Then the left shift gives ...

  f(x +3) = 2(x +3) -4 = 2x +2

__

The transformation "vertical compression by a factor of 1/2" is accomplished by multiplying the function by 1/2.

  g(x) = 1/2f(x +3) = (1/2)(2x +2)

  g(x) = x +1

__

In the attached, we wanted to show where the table points would end up if they were shifted left 3, then moved half their vertical distance toward the x-axis (compression by 1/2). Doing that, the points in the first table become the points in the second table. This is different from what you get when you simply substitute the same values of x into the new function g.

Consider, for instance, the bottom left point on the red graph. When it is moved 3 left, its coordinates are (-3, -4). When the y-coordinate is cut in half, its new location is (-3, -2), the bottom left point on the blue graph.

Hi there!

[tex]\large\boxed{cos(\frac{\theta}{2} )= \frac{3}{\sqrt{7}}}[/tex]

[tex]\large\boxed{tan(\frac{\theta}{2}) = \frac{\sqrt{5}}{3}}[/tex]

Begin by recalling that:

sin(θ) = O/H,  so:

Opposite side = 3√5

Hypotenuse = 7

We can solve for the adjacent sign using the Pythagorean Theorem:

7² = (3√5)² + b²

49 = 45 + b²

b² = 4

b = 2.

Thus, cosθ = 2/ 7

Use the half angle identity to solve for cos(θ/2):

cos(θ/2) = √(1 + cosθ)

Plug in the value of cosθ:

= √(1 + 2/7) = √9/7, or 3 /√7

Thus:

[tex]cos(\frac{\theta}{2}) = \frac{3}{\sqrt{7}}[/tex]

Calculate tan(θ/2) using the same process but with a different formula:

tan(θ/2) = √(1 - cosθ / 1 + cosθ)

Substitute in the value of cosθ:

tan(θ/2) = √(1 - 2/7)/(1 + 2/7)

= √(5/7)/(9/7) = √5/9 = √5/3
