Answer:

x-int: (-12/9, 0)

y-int: (0, 6)

Step-by-step explanation:

x-int ==> on x-axis when y=0

y-int ==> on y-axis when x=0

9/4x -1/2y = -3

x-int: 9/4x -1/2(0) = -3

9/4x = -3

9x/4 = -3

9x*4/4=-3*4

9x=-12

x=-12/9 ==> x-int: (-12/9, 0)

y-int: 9/4(0) -1/2y = -3

-1/2y = -3

1/2y=3

y/2=3

y=6 ==> y-int: (0, 6)

The sum of the given arithmetic series (-3)+(-6)+(-9)+. . . . . . +(-30) is  -165

The given series is:

     (-3)+(-6)+(-9)+. . . . . . +(-30)

First, we need to find how many terms in that arithmetic series.

Recall, the formula for the nth term of an arithmetic sequence is:

a(n) = a(1) + (n-1) . d

From the given series we know that:

the first term : a(1) = -3

the last term: a(n) = -30

the common difference: d = -6 - (-3) = -3

Substitute these parameters into the formula:

a(n) = a(1) + (n-1) . d

-30 = -3 + (n-1) . (-3)

-30 = -3n

n = 10

So there 10 terms in the series.

Use the sum formula:

S(n) = n/2 [a(1) + a(n)]

S(10) = 10/2 [-3 + (-30)]

S(10) = -330/2 = -165

Addition of two fractions which are both less than (1/2) must result in a fraction which is always less than 1.

A fraction represents a part of a whole or, more generally, any number of equal parts. A fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

Given data

The fractions can be represented as follows;

x < ½   and y < ½

The sum of both of the inequalities is;

x + y < ([tex]\frac{1}{4}[/tex]) + ([tex]\frac{1}{4}[/tex])

x + y < ½

Examples are-

[tex]\frac{1}{5}[/tex]+ [tex]\frac{2}{3}[/tex] =[tex]\frac{13}{15}[/tex]

¼ + ½ = ¾

[tex]\frac{1}{2}[/tex] +[tex]\frac{1}{3}[/tex] = [tex]\frac{5}{6}[/tex]

In the sample that is used number of viruses were 6000 times greater than the number of protozoa.

Sampling is the process of choosing a subset of people (a statistical sample) from a statistical population in order to estimate characteristics of the entire population.

Given the number of protozoa in the sample as 5 × 10⁵ and the number of viruses in the sample as 3x10⁹.

This is represented in the scientific notation.

To calculate the number of times the viruses in the sample is more than the protozoa in the sample we divide the amount of virus by the amount of protozoa.

∴ (3x10⁹) ÷ (5 × 10⁵)

= 6000

Therefore in the sample that is used number of viruses were 6000 times greater than the number of protozoa.

Use the formula L(x)=f(a)+f'(a)(x−a) to find the linearization.

Step-by-step explanation:

The triangle with vertices J(5 , 0), K(5 , -8), and L(0 , 0) has its circumcenter located at Point (5/2 , -4).

Circumcenter of a triangle refers to the point inside a triangle at which the perpendicular bisectors of the sides of a triangle intersect. This point is also equidistant from the three vertices.

Given the location of the three vertices, there are different methods that can be used to locate the circumcenter of the triangle.

One method is to calculate the intersection point of any two perpendicular bisectors.

First is to find the midpoint of the two sides given the formula:

midpoint = M(xm ,ym) = [(x1 + x2)/2 , (y1 + y2)/2]

Consider side JK and side KL.

JK : midpoint = [(5 + 5)/2 , (0 + -8)/2] = (5 , -4)

KL : midpoint = [(5 + 0)/2 , (-8 + 0)/2] = (5/2 , -4)

Next, solve for the slope of each side and slope of its perpendicular bisector (-1/m).

m = (y2 - y1)/(x2 - x1)

JK : m = (-8 - 0)/(5 - 5) = -8/0 = 0/8 = 0

KL : m = (0 - -8)/(0 - 5) = 8/-5 = 5/8

Using the midpoint and the slope of the perpendicular bisector, set up its equation using the point-slope form.

(y - ym) = -1/m(x - xm)

JK : (y - -4) = 0(x - 5)

y + 4 = 0

y = -4

KL : (y - -4) = 5/8(x - 5/2)

y + 4 = 5/8 x - 25/16

y = 5/8 x - 89/16

Find the intersection (circumcenter of the triangle) of these two perpendicular bisectors.

Since from the equation 1, y = -4, input this value to the 2nd equation.

y = 5/8 x - 89/16

-4 = 5/8 x - 89/16

5/8 x = 25/16

x = 5/2

y = -4

Hence, the circumcenter is at Point (5/2 , -4).

Answer:

Let y = length of side parallel to the side with no fence

x = length of each of the other two sides

Then, y+2x = 64. So, y = 64-2x

Area = A = xy = x(64-2x)

The graph of the area function is a parabola opening downward with a highest point and with x-intercepts (0,0) and (32,0).

By the symmetry of the parabola, the x-coordinate of the maximum point lies halfway between the x-intercepts.

So, the area is maximized when x = 16 ft

y = 64 - 2x = 32 ft

Maximum area = xy = (16)(32) = 512 ft2

To maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of y

let k be the constant of proportion

When a quantity varies directly with others, then we have a relation, y = kx,       —-- 1

Now, find k for given x = 15 and y = 25, we need to put these values in equation 1, i.e.

25 = k(15)

k = 25 / 15

k = 5 / 3

Further calculate y for given x = 6 and constant of proportion = 5/3 i.e.

y = (6)(5 / 3)

y = 10

Hence, the required value of y is 10.

Answer: |t - 15| ≤ 30 ; -30 ≤ t - 15 ≤ 30

Step-by-step explanation:

To set up the equation, we have to find the center, and the tolerance, so that we can use formula "|x - c| ≤ t"

First, we can find the tolerance by adding both number, then dividing by 2 --> -15 + 45 = 30 --> 30/2 = 15, so we now know that the center is 15

Next, we can find the tolerance by finding the distance between the center and one of the number --> 15 - (-15) = 30, so we now know that the tolerance is 30

Now we can set up our equation,

center (c) = 15

tolerance (t) = 30

|t - 15| ≤ 30

Now that we have our equation, we can set up the inequality

|x - c| ≤ t = -t ≤ x - c ≤ t

so,

-30 ≤ t - 15 ≤ 30

Given that,
Magdalena runs 5 days per week. Her goal is to run a minimum of 60 km each week. If she runs 50 days, what is the minimum distance she will run is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
In 5 days she ran 60 km
In one day she ran = 60 / 5 = 12
