Answer:

a) The slope of the function is 3.

c) The equation is represented by $n(t) = 3\cdot t + 35$ .

d) The y-intercept of the function is 35.

Step-by-step explanation:

a) According to the statement, we must assume that number of pieces of mail that must be hand-sorted (dependent variable) is represented by a linear function in terms of time (independent variable). That is:

$n(t) = m\cdot t + n_{o}$ (1)

Where:

$m$ - Slope, measured in number of pieces per minute.

$t$ - Time, measured in minutes.

$n_{o}$ - Initial number of pieces of mail that must be hand-sorted (y-intercept), measured in pieces.

$n$ - Current number of pieces of mail that must be hand-sorted, measured in pieces.

From Geometry, we know that a line can be formed by know two distinct points. If we know that $n(15\,min) = 80\,p$ and $n(45\,min) = 170\,p$ , then the following system of linear equations is formed:

$15\cdot m + n_{o} = 80$ (2)

$45\cdot m + n_{o} = 170$ (3)

The solution of the system of equations is:

$m = 3$ and $n_{o} = 35$

The slope of the function is 3.

c) By (1) and using results from a) we conclude that the equation function is:

$n(t) = 3\cdot t + 35$ (4)

d) The y-intercept of the function is 35.

How many roots do u thinn

hram777 [196]

Answer:

2 roots
1 root

Step-by-step explanation:

Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).

y = a(x -h)^2 +k

has leading coefficient "a" and vertex (h, k).

f(x) = 1/3(x +5)^2 +7

vertex: (-5, 7), opens downward

The vertex is above the x-axis, so there are two real roots.

f(x) = -5(x -3)^2

vertex: (3, 0), opens downward

The vertex is on the x-axis, so there is one real root.

Find the length of the missing side of the triangle to the nearest tenth.

babymother [125]

Hey! So you’re gonna need to use the Pythagorean Theorem (a^2 + b^2 = c^2).
You’re looking for one of the legs here, so after inputting the values your equations should look like this: 6^2 + b^2 = 10^2.
Next, find what the numbers squared are: 36 + b^2 = 100.
Then, isolate the variable: b^2 = 64.
Lastly, square root both sides: √b^2 = √64.
You should find the answer is 8.
