guy pls help me!!!!!

It sounds like your teacher wants g = 2c as the answer. The constant of proportionality simply tells us what to multiply the input variable by, to get the output variable.

It's similar to saying y = 2x, but we use c in place of x and use g in place of y.

Step-by-step explanation:

(1 - cos²A) (1 + tan²A) = tan²A

(sin²A)(sec²A) = tan²A

(sin²A)(1/cos²A) = tan²A

(sin²A)/(cos²A) = tan²A

tan²A = tan²A → Proved

So, this way we can do. Thank you!

Here's the solution in attachment :

Answer:  Let the 2 numbers be x and  

sum of two numbers is 28....Eq 1:  x + y = 28

sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2:  6x + 3y = 105

Rearrange Eq 1 to solve for x.

x + y = 28

x = 28 - y  --> Substitute into Eq 2, you get

6(28 - y) + 3y = 105

168 - 6y + 3y = 105

-3y = -63

y = -63 / -3 = 21

Now solve for x using Eq 1.

x = 28 - y = 28 - 21 = 7

hope  it helped

Step-by-step explanation:

you would ave the denominator to make them both 20 then the fractions would become 5/20 and 8/20 so it would be the son who washed the most. then add them together and get 13/20 so 7/20 laundry needs to be done

Using proportions, it is found that each out is [tex]\frac{1}{54}[/tex] of all the outs in a 9-inning baseball game.

Supposing a 9-inning baseball game, each team has the right to 27 outs.

Two teams, thus, there are [tex]2 \times 27 = 54[/tex] outs.

This means that each out in a game [tex]\frac{1}{54}[/tex] of all the outs in a 9-inning baseball game.

Amy because Ben spend the less money then

amy get more money

Amy has more money than her brother after all transactions.

An equation is a statement that the depicts the values of two mathematical expressions as equal using an (=) sign. Example -

2x = 5

An expression is written using individual terms (either constant or variable) separated by mathematical operations. Example -

3x + 5y + 3

We have Amy who has $1275 less than her brother ben. Ben spends $550 and Amy gets $750.

Assume that the money with Ben and Amy after transactions is $x and $y respectively. Let Ben has a initial amount of $m and Amy has of $n.

n = m - 1275

After transactions -

x = m - 550

y = m - 1275 + 750 = m - 525

Now -

m - 525 > m - 550  for every value of [m].

So, now Amy has more money.

Therefore, Amy has more money than her brother after all transactions.

The question is an illustration of related rates.

The rate of change between you and the ball is 0.01 rad per second

I added an attachment to illustrate the given parameters.

The representations on the attachment are:

[tex]\mathbf{x = 100\ m}[/tex]

[tex]\mathbf{\frac{dy}{dt} = 2\ ms^{-1}}[/tex] ---- the rate

[tex]\mathbf{\theta = \frac{\pi}{4}}[/tex]

First, we calculate the vertical distance (y) using tangent ratio

[tex]\mathbf{\tan(\theta) = \frac{y}{x}}[/tex]

Substitute 100 for x

[tex]\mathbf{y = 100\tan(\theta) }[/tex]

[tex]\mathbf{\tan(\theta) = \frac{y}{100}}[/tex]

Differentiate both sides with respect to time (t)

[tex]\mathbf{ \sec^2(\theta) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot \frac{dy}{dt}}[/tex]

Substitute values for the rates and [tex]\mathbf{\theta }[/tex]

[tex]\mathbf{ \sec^2(\pi/4) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

This gives

[tex]\mathbf{ (\sqrt 2)^2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

[tex]\mathbf{ 2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

Divide both sides by 2

[tex]\mathbf{ \frac{d\theta}{dt} = \frac{1}{100} }[/tex]

[tex]\mathbf{ \frac{d\theta}{dt} = 0.01 }[/tex]

Hence, the rate of change between you and the ball is 0.01 rad per second

The total amount in the account after 1 year will be $420

Based on the information given, the following can be deduced:

Principal = $400

Interest rate = 5%

Time = 1 year

Therefore, the simple Interest will be:

= PRT/100

= ($400 × 5 × 1)/100

= $2000/100

= $20

Therefore, the amount will then be:

= Principal + Interest

= $400 + $20

= $420

Therefore, the total amount is $420

The value of the function g(h(10)) will be 2√2.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given that g(x) is √(x-4) and h(x) is 2x - 8. The value of the function g(h(10)) will be calculated as:-

h(x) = 2x - 8

At x = 10 the value of the function h(x) will be:-

h(10) = ( 2 x 10 ) - 8

h(10) = 20 - 8

h(10 ) = 12

Calculate the value of the function g(h(10)):-

g(h(10)) = √(x-4)

g(h(10)) = √(h(10)-4)

g(h(10)) = √( 12 -4 )

g(h(10)) = √( 8 )

g(h(10)) =  2√2.

Therefore, the value of the function g(h(10)) will be 2√2.
