Use the Law of Sines to write an expression that represents angle measure x.

Answers

Answer:

  x° = arcsin(15.5/26.9×sin(73°))

Step-by-step explanation:

The law of sines tells you the sine of an angle is proportional to the length of the opposite side:

  sin(x°)/15.5 = sin(73°)/26.9

  sin(x°) = (15.5/26.9)sin(73°) . . . . . multiply by 15.5

Using the inverse function, we can find x.

  x° = arcsin((15.5/26.9)sin(73°))

What is f(3) if f(x) = - 4x+1 ?

B.-11
C. 1/2
D. 13

Please help me! :/

Answers

Answer:

Here is the equation:

f(x)=4x+1f(x)=4x+1

You need to find f(3). To do that, substitute all the x's with 3:

f(x)=4x+1 \rightarrow f(3)=4\times3 + 1f(x)=4x+1→f(3)=4×3+1

The first thing you need to do is multiply 4 by 3. Multiply:

4 \times 3 = 124×3=12

Here is your new equation:

f(3)=12+1f(3)=12+1

To get your answer, you need to add 12 and 1. Add:

12+1 = 1312+1=13

That means:

\bf f(3)=13f(3)=13

Consider the equation:
0 = x^2 - 10x + 10
1) Rewrite the equation by completing the square.
Your equation should look like (x + a)2 = b or (x - c)2 = d.

Answers

x² - 10x + 10 = 0

Isolate the constant term

x² - 10x = -10

Complete the square
• coefficient of the x term: -10
• divide in half: -5
• square it: (-5)² = 5²
• add 5² to both sides, to complete the square and keep the equation balanced:
x² - 10x + 5² = -10 + 5²
(x-5)² = 15

Answer:

1) We can rewrite the equation as 15=(x-5)^2

2) The solutions to the equation are x=5±15

Are the two expressions in the equation 2b + 5 + 1b = 3b + 5 equal or equivalent? How do you know

Answers

Given:

The expression is

[tex]2b+5+1b=3b+5[/tex]

To find:

Whether the two expression in the equation are equal or equivalent.

Solution:

If two expression are exactly the same, then they are equal and if the two expressions are different but the after simplification both are same, then they are called equivalent expressions.

We have,

[tex]2b+5+1b=3b+5[/tex]

Taking LHS, we get

[tex]LHS=2b+5+1b[/tex]

On combining liker terms, we get

[tex]LHS=(2b+1b)+5[/tex]

[tex]LHS=3b+5[/tex]

[tex]LHS=RHS[/tex]

In the given equation both expression are different but after simplification LHS = RHS, therefore the expression are equivalent not equal.

Answers

Median = 6, Lower quartile = 5; Upper quartile = 7; Interquartile range =2

What are Lower quartile and Upper quartile?

The numbers that divide a piece of data into four equal portions are known as quartiles. A data set is divided in half by its median. The lower quartile (LQ) is the median value for the lowest half of a set of data. The upper quartile (UQ) is the median value for the higher half of a set of data.

Given data is:

7, 5, 3, 8, 6.

in ascending order the data is:

3, 5, 6, 7,8.

Hence, the median is = middle number from the data =   6.

The Lower quartile is =middle number from the lower part of the data = 5

The Upper quartile is = middle number from the data =7.

hence, the Interquartile range  is = upper quartile - lower quartile

= 7 - 5

= 2.

Describe how a root can be written using a rational exponent. Give an example.

Answers

Answer:

sqrt(x)=x^1/2

Step-by-step explanation:

The root of a number is the same as writing that number to 1 over the root. In a square root, it is what number multiplied by itself (x*x), as you can see there are two, so it is that number to the 1/2 power. another example is something to the seventh power. that is calculating what number multiplied by itself 7 times would equal the nmber you are taking the root of. (x*x*x*x*x*x*x) so this would be a number to the 1/7 power.

A package designer wants the hexagonal base of a hat box to have an area of

about 200 in.2. About how long is each side?

Answers

Answer:

About 9inches long

Step-by-step explanation:

Area of a hexagon = 3√3/2 a²

a is the length of each side

Given

Area of the hexagon = 200in²

Substitute

200 = 3√3/2 a²

200×2 = 3√3 a²

400 = 3√3a²

a² = 400/3√3

a² = 400/5.196

a² = 76.982

a = √76.982

a = 8.774

Hence the length of each side is about 9inches long (to nearest inches)

We need to find multiple divisions, it says  1/4 divided by 2 then go back to 1/4 and divide it again but by 3 then go back to it again and divide it by 4 then go back to 1/4 and divide it by 5.

We will take one by one

(1) 1/4 divides by 2 will be  = 1/8

(2) 1/4 divided by 3 = 1/12

(3) 1/4 divided by 4 = 1/16

(4) 1/4 divided by 5 =1/20

These results are obtained by dividing the given parts, as the given Numerator is in fraction so whatever will be divided from the fractional numerator will get multiplied with the denominator.

To solve, you need to use Pythagorean Theorum

a^2+b^2=c^2

100^2+53.33^2 = c^2

10,000+2844.0889=c^2

Solve for x: 7x + 3 =2x +13

Answers

Answer:

x = 2

Step-by-step explanation:

7x + 3 = 2x + 13

Get all the x on the same side: 7x - 2x = 13 - 3

Subtract: 5x = 10

Divide both sides by 5 to get x = 2.

Plug the found value of x back in to check the answer: 7(2) + 3 = 2(2) + 13

Multiply: 14 + 3 = 4 + 13

Add: 17 = 17

This verifies that x = 2.
