23. Find the perimeter and area of the rectangle below. 10x^2 7xy^2

**Answer:**

Area= 70x^3y^2

Perimeter = 20x^2 + 14 xy^2

**Step-by-step explanation:**

Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 . The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.

A model rocket is launched directly upward at a speed of 20 meters per second from the ground. The function f(t)=−4.9t2+20t, models the relationship between the height of the rocket and the time after launch, t, in seconds. When, in seconds after launch, will the rocket reach its highest point? Round to two decimal places.

**Answer:**

The rocket will reach its highest point about 2.04 seconds.

**Step-by-step explanation:**

The function:

[tex]f(t)=-4.9t^2+20t[/tex]

Models the relationship between the height of the rocket and the time after launch t in seconds.

Since this is a quadratic function, the rocket will reach its highest point at its vertex. The vertex of a quadratic is given by:

[tex]\displaystyle \Big(-\frac{b}{2a}, f\Big(-\frac{b}{2a}\Big)\Big)[/tex]

In this case, a = -4.9, b = 20, and c = 0. Thus:

[tex]\displaystyle t=\frac{-(20)}{2(-4.9)}=\frac{10}{4.9}\approx 2.04[/tex]

The rocket reaches its maximum height after 10/4.9 or about 2.04 seconds.

Further Notes:

Then the maximum height of the rocket will be f(10/4.9):

[tex]\displaystyle f\Big(\frac{10}{4.9}\Big)=-4.9\Big(\frac{10}{4.9}\Big)^2+20\Big(\frac{10}{4.9}\Big)\approx20.41\text{ feet}[/tex]

Solve the equation.

h-3.5 =9h−3.5=9

**i am a legend **

**dont ask i am just a lengnd**

The value of h in the **equation **h - 3.5 = 9 is 12.5.

Mathematically, an equation is a statement that asserts the **equivalency **of two **expressions**. It consists of two hands, the left-hand side( LHS) and the right-hand side( RHS), separated by an equal sign( =). The LHS and RHS can be numbers, variables, constants, or further **complex** fine **expressions**.

Equations can be classified based on their **degree**, which corresponds to the highest **power** of the variables involved. For example, linear equations have a degree of 1, **quadratic **equations have a degree of 2, and so on.

Given that

h - 3.5 = 9,

Add 3.5 on both sides,

h - 3.5 + 3.5 = 9 + 3.5,

h = 12.5.

So, the value of h is 12.5.

The probability that a seed will germinate is 0.65. Find the probability that a seed selected at a random will not germinate. *

**Answer:**

**0.35 or 35%**

**Step-by-step explanation:**

The probability that **any **seed will germinate is said to be 0.65 (or 65%) in the question. This means that the remaining percentage is the probability that the randomly selected seed will not germinate. This is because there is only two possible outcomes to that given scenario, which is it will germinate or not. Meaning that the remaining percentage/probability is that it will not germinate

1 - 0.65 = **0.35 or 35%**

**Answer:**

** Option A**

**Step-by-step explanation:**

Number of components assembled by the new employee per day,

N(t) = [tex]\frac{50t}{t+4}[/tex]

Number of components assembled by the experienced employee per day,

E(t) = [tex]\frac{70t}{t+3}[/tex]

Difference in number of components assembled per day by experienced ane new employee

D(t)= E(t) - N(t)

D(t) = [tex]\frac{70t}{t+3}-\frac{50t}{t+4}[/tex]

= [tex]\frac{70t(t+4)-50t(t+3)}{(t+3)(t+4)}[/tex]

= [tex]\frac{70t^2+280t-50t^2-150t}{(t+3)(t+4)}[/tex]
