All that apply are:

The slope is 0.

The y-intercept is -2

The line is horizontal.

The equation of the line is Y = -2.

Given points:

(1,-2) and (4,-2)

slope m = -2-(-2) / 4 - 1

= -2+2/3

= 0

so slope is 0

y = mx + c

(1,-2) passes

-2 = 0*1 + c

c = -2

y = 0*x + -2

y = -2

so the line is horizontal and equation of the line is y = -2.

The y-intercept is -2.

Answer:

60/15

Step-by-step explanation:

A fraction is simply a portion of a whole number, so 1/15 is the number 1 split into fifteen equal parts, therefore 15/15 = 1.

So 4 as a fraction with fifteen as the denominator would be 15/15 x 4, which equals 60/15.

The equation of a line in y = mx + b form that passes through (5,-5) and (-5, -3) is y = (-1/5)x - 4.

The formula to calculate the slope between two points is equal to

[tex]m = y2-y1/(x2-x1)[/tex]

Find the slope of Line a

We have the points

(5,-5) and (-5, -3)

Substituting the value in the formula

[tex]m = -3 - (-5)/(-5-5)\\m = (-3 + 5)/(-10)\\m = 2/-10\\m = -1/5[/tex]

The slope is -1/5.

Finding the y-intercept from the below-given equation:

y = mx + b ...... (1)

Putting value of y = - 5, x = 5, m = -1/5

-5  = (-1/5) x (5) + b

-5 = - 1 + b

=> b = - 4

Putting the value of b = - 4 and m = -1/5 in equation (1). We get,

y = (-1/5)x - 4

Hence, the equation of the line is y = (-1/5)x - 4.

The drug administered to the patient by the doctor has a half-life of 5 hours

Half-life is the time required for a quantity to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential decay.

The formula is given as;

T1/2 = ln2 / λ

If It is estimated that the sanctuary can sustain up to 600 deer. Absent constraints, the population would grow by 70% per year. After one year is 85 and after two years is 144.50.

Using this formula

A = P(1+r)t

Where:

A = Amount

P = Principal

r =Interest rate

t = time

Let plug in the formula

After one year:

A = 50(1+0.70)^1

A = 50(1.70)^1

A= 85 deer

After two years:

The polynomial of p(x) is 20/13(x³+4x²-9x-36) with the satisfying's conditions degree 3.

Given that,

An nth degree polynomial p meets the requirements listed below:

p is of degree 3.

-3 is a multiplicity 1 zero of p.

-4 is a zero, with multiplicity 1, of p.

3 is a root, with multiplicity 1, of p.

p(-2)=-40

We have to determine an nth degree polynomial that satisfier the conditions.

Let the polynomial be p(x) whose zero are -3,-4 and 3.

a be the coefficient.

p(x)=a(x+3)(x+4)(x-3)

p(x)=a(x²-3²)(x+4)

p(x)=a(x²-9)(x+4)

p(x)=a(x³+4x²-9x-36)

Now, take x=-2

p(-2)=a((-2)³+4(-2)²-(-2)-36)

-40=a(-8+16+2-36)

-40=a(-26)

a=-40/-26

a=40/26

a=20/13

We get,

p(x)=20/13((x+3)(x+4)(x-3))

p(x)=20/13(x³+4x²-9x-36)

The equation for the parabola with the given characteristics is:

y = (2/35)*(x + 7)*(x - 5)

We know that for a parabola that has the zeros x₁ and x₂, and a leading coefficient a, can be written as:

y = a*(x - x₁)*(x - x₂)

In this case, the roots (zeros) are at X =-7 and x = 5

Then we can write:

y = a*(x + 7)*(x - 5)

Now we also know that it passes through the point (0, -2), then we can write:

-2  =a*(0 + 7)*(0 - 5)

-2 = a*-35
