Hello there! the winning time is 59.625 seconds.

This is the person who completed the lowest amount of time, meaning they finished first. The others too longer so they finished later, meaning they didn't win.

I hope this was helpful and have a great day! :)

M/n = p/q solve for p

mojhsa [17]

Answer:

$p=\frac{Mq}{n}$

Step-by-step explanation:

we have

$\frac{M}{n}=\frac{p}{q}$

Solve for p

That means ----> Isolate the variable p

Multiply by q both sides

$\frac{M}{n}(q)=\frac{p}{q}(q)$

Simplify right side

$\frac{M}{n}(q)=p$

Rewrite

$p=\frac{Mq}{n}$

What is the range of f(x) = A cos(x) +b or<br> g(x) = A sin(x)+b?

vagabundo [1.1K]

Answer:

Step-by-step explanation:

The range of f(x) = cos(x) is [-1, 1].

That of f(x) = A cos(x) is [-A, A], and

That of f(x) = A cos(x) + 2 is [ b-A, b+A ].

The function g(x) = A sin(x)+b has the same range.

Can I please have the answers.

Question 22.). Write the equation in Standard Form:

10y = 12x + 0.7

Identify: A, B, C

Standard Form for Linear Equation: Ax + By = C

10y = 12x + 0.7

The Standard Form of the solution is

Ax + By = C, Where, A ≥ 0

A and B, are Non- Zero numbers.

Therefore, Your answer, Letter Choice, (D), 120x - 100y = - 7, Where,

A = 120, B = - 100, and C = - 7

Question 24.). Described as, Inconsistent, Consistent, and Independent, Consistent, and Dependent, or None of These.

9x - 8y = 15, and 27x - 24y = 3

Solve:

9x - 8y = 15; 27x - 24y = 3

Steps: I will try to solve the system of equation:

9x - 8y = 15; 27x - 24y = 3

Step, Solve: 9x - 8y = 15 for x

9x - 8y + 8y = 15 + 8y

Add 8y to both sides:

9x = 8y + 15

9x/9 = 8y + 15/9 ( Divide both sides by 9):

x = 8/9y + 5/3

Step Substitute:

8/9y + 5/3 for X in 27x - 24y = 3

27x - 24y = 3

27 ( 8/9y + 5/3) - 24y = 3

45 = 3

Simplify Both sides of equation:

45 + - 45 = 3 + - 45 ( Add - 45, to both sides.):

0 = - 42

Therefore, No real Solutions, to both Equation.

Hence; 9x - 8y = 15; and 27x - 24 = 3, have No Real Solutions, and Therefore, They are, Answer Letter Choice, (B), Inconsistent.

Hope that helps!!! Sorry, I couldn't figure out Number (23.). : )

A certain forest covers an area of 2600 km2. Suppose that each year this area decreases by 7.75%. What will the area be like aft

kakasveta [241]

Answer:

After 15 years, the area will be of 775.3 km²

Step-by-step explanation:

The equation for the area of the forest after t years has the following format.

$A(t) = A(0)(1-r)^{t}$

In which A(0) is the initial area and r is the yearly decrease rate.

A certain forest covers an area of 2600 km2.

This means that $A(0) = 2600$

Suppose that each year this area decreases by 7.75%.

This means that $r = 0.0775$

$A(t) = 2600(1-0.0775)^{t}$

$A(t) = 2600(0.9225)^{t}$

What will the area be like after 15 years?

This is $A(15)$

$A(t) = 2600(0.9225)^{t}$

$A(15) = 2600(0.9225)^{15} = 775.3$

After 15 years, the area will be of 775.3 km²
