Using the given equation find the missing coordinates of the points and then find the slope of the line for each equation y=3.5x+4; a(...; 5), b(10; ...)

Answers

A(2/7:5)

B(10:39)

The slope is 7/2.

The slope of the line y=3.5x+4 is 3.5, and the missing coordinates will be filled as a(0.28, 5) and b(10, 9)

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given equation of line is y=3.5x+4

When we compare this with slope intercept form y=mx+b.

slope m=3.5

We need to find the value of x when y is 5

5=3.5x+4

1=3.5x

Divide both sides by 3.5

x=0.28

So a coordinates are (0.28, 5)

Now let us find y value when x is 10

y=3.5(10)+4

y=39

So b coordinates are (0.28, 39)

Hence, the slope of the line y=3.5x+4 is 3.5, and the missing coordinates will be filled as a(0.28, 5) and b(10, 9)

simplify 6/x-6+3x/x+5-1/(x-6)(x+5)

Answers

Final answer:

To simplify a complex algebraic expression, you handle fractions first by bringing them to a common denominator. However, the resources provided seem misplaced as they pertain to calculus rules and Chemistry, which are not relevant to this algebra question.

Explanation:

The student's question is asking to simplify a complex algebraic expression: 6/x-6+3x/x+5-1/(x-6)(x+5). To simplify such an expression, it's best to deal with fractions first. Note that the given expression can also be expressed as three separate fractions summed together, i.e., (6/x-6) + (3x/x+5) - [1/(x-6)(x+5)]. Dealing with fractions in simplification, we combine them to a common denominator and rationalize the numerator and denominator. After that, simplify the resulting expression. However, with provided reference, it seems that there is a misunderstanding or a misplacement of information because resources given are about calculus rules and Chemistry which are not relevant in simplifying this algebraic expression.

Answer:

The annual interest is,

Option d is correct

The bank compounds the interest_

Option a is correct.

Annually.

The balance of the account will grow,

Option b is correct

exponentially

Step-by-step explanation:

Exponential growth function is given by:

[tex]y=(1+r)^x[/tex] .....[1]

where,

r is the annual interest in decimal

x is the number of periods.

As per the statement:

Consider the function:

[tex]y=(1.05)^{\frac{x}{12}}[/tex] where, x represents the time in months.

On comparing with [1] we have;

[tex]1+r = 1.05[/tex]

Subtract 1 from both sides we have;

r = 0.05 = 5%

The annual interest is, 5%

and

the bank compounds the interest annually.

The balance of the account will grow exponentially

What are the zeros of f(x) = 4x^2 - 12x + 8 (I need a clear explanation on how to solve it)

Answers

The zero of the quadratic function is therefore x = 1. Since both factors give the same zero, we have a repeated zero and f(x) only touches the x-axis at one point, x = 1.

The zeros of the quadratic function f(x) = 4x^2 - 12x + 8 are the values of x that make f(x) = 0. In this function, we can factor by finding two numbers that multiply to give the constant term (8 times 4, the coefficient of x^2) and add to give the coefficient of x (-12). Here, those numbers are -4 and -4, so we rewrite the middle term -12x as -4x - 4x, and factor by grouping:

4x^2 - 4x - 4x + 8 = 0

4x(x - 1) - 4(x - 1) = 0

(4x - 4)(x - 1) = 0

Now we have two factors equal to zero, which gives us two equations to solve:

4x - 4 = 0 or x - 1 = 0

x = 1

Answer: The time is takes to cook a turkey is a function of the turkey's weight.

In a function, there is an input and there is an output. The idea of a function is that each individual input is changed into an output.

The time it takes to cook a turkey depends on the size of the turkey.
Smaller turkeys would take less time to cook and larger turkeys would take longer to cook.

So if you start with the turkeys weight, you could determine how long it would need to cook. This is an example of a function.

The time it takes to cook a turkey is a function of the turkey’s weight. Then the correct option is C.

b. Find CD, the height of the plane from the ground, to the nearest foot.

Answers

the complete question in the attached figure

Part A) Find BC, the distance from Tower 2 to the plane, to the nearest foot.

in the triangle ACD
sin16=CD/(7600+BD)--------> CD=sin16*(7600+BD)---------> equation 1

in the triangle BCD
sin24=CD/BD-----------> CD=sin24*BD---------------> equation 2

equation 1=equation 2
sin16*(7600+BD)=sin24*BD-----> sin16*7600+sin16*BD=sin24*BD
sin24*BD-sin16*BD=sin16*7600----> BD=[sin16*7600]/[sin24-sin16]
BD=15979 ft

in the triangle BCD
cos24=BD/BC---------> BC=BD/cos24-------> 15979/cos24-------> 17491
BC=17491 ft

the answer part 1) BC is 17491 ft

Part 2) Find CD, the height of the plane from the ground, to the nearest foot.

CD=sin24*BD ( remember equation 2)
BD=15979 ft
CD=sin24*15979 -----------> CD=6499 ft
