Find cos(a) Reduce the ratio if necessary

Find Cos(a) Reduce The Ratio If Necessary

Answers

Answer 1

Answer:

3/5 Choice 4.

Step-by-step explanation:

Remember SOH, CAH, TOA.

Sine=opposite/hypotenuse

Cosine=Adjacent/hypotenuse

Tangent=Opposite/adjacent.

Since we are looking for Cosine, we would need to locate the adjacent and hypotenuse of angle a.

The hypotenuse is the easiest to find because that will simply be the longest side of the triangle(50)

The adjacent would be 30 because 40 is the opposite(right across from theta).

So, A=30

H=50

Simply that to get Cos(A)=[tex]\frac{3}{5}[/tex].

Anyone know how to do this

Answer:

Look in explanation

Step-by-step explanation:

I will assume that you're trying to solve for "x".

For number 1: 49+(5x+1) is a supplementary angle(180 degrees) so you can subtract 180-49 to get 131.

Now, 131 = 5x+1

        -1            -1

         130 = 5x

         /5      /5

Now, we isolate the x to get x=26.

Number 2: There is a supplementary angle as well so we can put 5x+12+6x+3=180.

Now, combine the like terms to get 11x+15=180 so we now isolate x.

                                                              -15   -15

                                                            11x=165

                                                            /11    /11

                                                               x=15

Now, try the rest and set the terms to 180.

5x+1+8+4x=180

2x+1+x-10=180

6+x+5x=180

x+2+153=180(This is similar to #1)

Keith reads 48 chapters of a book in 6 hours.
What is his rate in chapters per hour?

Answers

Answer:

Keith's rate in chapters per hour is 8.

Step-by-step explanation:

Divide his 48 chapters by the 6 hours he read and in total it will be a ratio of 8 chapters to one hour.

Keith's rate in chapters per hour will be 8.

What is unit rate?

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

We are given that Keith reads 48 chapters of a book in 6 hours.

Therefore,

We need to Divide his 48 chapters by the 6 hours he read

48/6

= 8

Hence, in total it will be a ratio of 8 chapters to one hour.

harold licorice company made 6,429.4 feet of licorice in 9 days. to the nearest hundredth of a foot how many feet of licorice on average did the company make per day​

Answers

Answer: 714.4

Step-by-step explanation: It says the company had made 6,429.4 feet of licorice in 9 days and you want to find the average amount made in 1 day. So what you would do is divide 6,429.4 by 9 and get 714.3777777 so on. Next its says by the nearest hundredths place meaning the 2nd placement after the dot, so what you would do is round it and you get 714.4.

First of what is the inverse of FX = 2x - 3

Answers

Answer: [tex]f^{-1}(x)=\frac{x+3}{2}[/tex]

Step-by-step explanation:

The inverse of an equation is when you switch the x-value with the y-value. The y-value is equal to f(x). So, your work will look something like this. Note the changes in bold.

f(x) = 2x - 3

f(x) = y

y = 2x - 3

x = 2y -3

x + 3 = 2y

[tex]\frac{x+3}{2}[/tex] = y

y = [tex]\frac{x+3}{2}[/tex] (here, I'm just switching it so the y-value is on the left to make it easier to read)

y = f(x)

[tex]f^{-1}[/tex](x) is the notation for inverse f(x)

So, the final equation would be written as

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

The rule for g(x) when vertically stretched by a factor of 5 followed by a horizontal shift right 2 units is [tex]5(x-2)^2[/tex]

Your question is not complete, it seems to be missing the following information below;

"If f(x) = x², write the rule for g(x)"

The general rules for the translation of a function is given below;

To stretch vertically by a factor of m = m·f (x)  To shrink vertically by a factor of m  = [tex]\frac{1}{m} f(x)[/tex]To shift a function horizontally  by m units to the right = f(x - m)To shift a function by m units up = f(x+ m)

The rule for g(x) when vertically stretched by a factor of 5 followed by a horizontal shift right 2 units is calculated as;

[tex]g(x) = f(5(x-2) )= 5(x-2)^2[/tex]

Answer:

JH = 15

Step-by-step explanation:

KJ = 10

KI = 14

IH = 11

JH = ?

In order to find JH, we need to find JI, then add it to IH, which is 11. Here's the equation:

JH = JI + 11

In order to find JI, we need to subtract KJ from KI. Here's the equation:

14(KI) - 10(KJ) = JI

14 - 10 = 4

JI = 4

Now we plug in the numbers from our first equation:

JH = JI + 11

JH = 4 + 11

JH = 15

Answer:

JH= 15

Step-by-step explanation:

Let KJ= 10, KI= 14, and IH= 11KI - KJ = J14 - 10 = 4J + IH = JH4 + 11 = 15
