Answer 1

Answer:

[tex]f(x)=x+2[/tex]

Step-by-step explanation:

Given parameters:

f(0) = 2f(2) = 4

Therefore, there are two points on the line:

(0, 2) and (2, 4)

The linear relationship between the x and y values is:

The y-value is 2 more than the x-value.  

[tex]\implies f(x)=x+2[/tex]

To prove this algebraically, define the points:

(x₁, y₁) = (0, 2)(x₂, y₂) = (2, 4)

Find the slope of the linear function by substituting the defined points into the slope formula:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-2}{2-0}=\dfrac{2}{2}=1[/tex]

Substitute the found slope and one of the points into the point-slope formula to create a linear function that satisfies the given parameters:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-2=1(x-0)[/tex]

[tex]\implies y-2=x[/tex]

[tex]\implies y=x+2[/tex]

Hence proving that the linear function is:

[tex]f(x)=x+2[/tex]

A ball manufacturer wants to stack three​ balls, each with an​ 8-centimeter diameter, in a box that is an equilateral triangular prism. The diagram shows the dimensions of the bases. Will the balls fit in the​ box? Explain how you know.

Answers

Considering the volumes of the ball and of the box, it is found that the balls will not fit into the box.

Volume of the ball

The ball is spherical, with a diameter of 8 inches = radius of 4 inches.

The volume of an sphere of radius r is given by:

V = 4/3πr³.

Hence the volume of each ball is given by:

V = 4/3π x 4³ = 267.4 cm³.

The volume of the three balls is:

V = 3 x 267.4 cm³ = 802.2 cm³.

Volume of the box

The box is a triangular prism, hence the volume is given by the multiplication of the base area by the height, as follows:

V = Ab x h.

The height of the box is of 9 cm, however we have to find the base area.

From the bisection, at the right side of the triangle, we have that half the side of the equilateral triangle is of 7.8 cm, hence the side length is of:

s = 2 x 7.8 = 15.6 cm.

Hence, bisecting the base triangle to find the height, it will have:

Height h. (side of a right triangle).Side of 7.8 cm (another side of a right triangle).Angle of 30º between them.

Then the height can be found as follows:

tan(30º) = h/7.8 (tangent = opposite side/adjacent side)

h = 7.8 x tan(30º)

h = 4.5 cm.

The area of a triangle is half the multiplication of the side length and the height, hence the base area is:

A = 0.5 x 15.6 x 4.5 = 35.1 cm².

Then the volume of the box is:

V = 35.1 x 9 = 315.9 cm³.

The volume of the three balls is of 802.2 cm³ > 315.9 cm³, hence the three balls will not fit into the box.

it is 76 degrees at the 6000 foot level of a mountain and 49 degrees at the 12000 foot level of the mountain. write a linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet

Answers

The linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet will be T = (-9/2)x +103.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that, it is 76 degrees at the 6000-foot level of a mountain and 49 degrees at the 12000-foot level of the mountain.

As we know the linear equation in the slope-intercept is found as,

y =mx + b

Replace m with the c,y with the T, and b with the k as

T = cx + k

From the given data,

76 = c(6) + k

76 = 6c + k

⇒ k = 76 - 6c

For condition 2,

49 = c(12) + k

49 = 12c + k

Substitute the value of k in the above equation,

49 = 12c + (76 - 6c)

49 = 12c + 76 - 6c

49 - 76 = 6c

6c = -27

c=-9/2

Put the value of c in the equation,

K = 76 -6c
K = 76 -6(9/2)

K = 76+27

k = 103

Put the value of c and k in the equation below,

T = cx + k

T  = (-9/2)x+103

Thus, the linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet will be T = (-9/2)x +103.

The sum of three numbers is 20. The third is 3 more than 12 times the second. 9 times the first is 11 less than 10 times the second. Find the numbers.

Answers

A three-number total equals twenty. The third is three times as much as the second. From the equation numbers area 0.1, 1.2 and 17.4.

Given that,

A three-number total equals twenty.

The third is three times as much as the second.

11 less than 10 times the second is 9 times the first.

We have to find the numbers.

First take the 3 numbers as a,b and c

A three-number total equals twenty.

We can write as,

a+b+c=20→ equation(1)

The third is three times as much as the second.

c=12b+3→equation(2)

11 less than 10 times the second is 9 times the first.

9a=10b-11→equation(3)

Now,

From equation(3) we get,

a=(10b-11)/9=10/9b-11/9

From equation(2) we get,

c=12b+3

Substitute value a and c in equation(1),

10/9b-11/9+b+12b+3=20

10b-11+9b+108b+27=20×9

127b+16=180

127b=180-16

127b=164

b=164/127

b=1.2

Substitute the b value in equation (2) and (3)

Equation(2)

c=12b+3

c=12(1.2)+3

c=14.4+3

c=17.4

Equation(3)

a=10/9b-11/9

a=10/9(1.2)-11/9

a=1.3-1.2

a=0.1

Therefore, the numbers are 0.1, 1.2 and 17.4.

Answer:

Step-by-step explanation:

Given:

General Equation:

a·x² + b·x + c = 0

a = 3;

b = 7;

c = - 6.

Discriminant:

D = b² - 4·a·c = 7² - 4·3·(-6) = 49 + 72 =  121

-2/3a + 2/3a -2 = 5/3a + 2/3a -19

Combine like terms

-2 = 7/3a -19

Add 19 to both sides to isolate variable

-2 +19 = 7/3a -19 + 19

17 = 7/3a

Divide both sides by 7/3 to solve for a

Answers

The total number of the boys and girls in that class were equal, then 27 boys stated that they liked basketball while 18 stated that they liked kickball.

As per the question statement, in a P.E. class, when the boys and girls were asked about their favorite sport, for every three boys who stated they like basketball, two boys liked kickball, while the girls' survey reported that, for every four girls that like basketball, one liked kickball, and 36 girls said they liked basketball.

Since there is no other information provided in the question statement, we are assuming that the total number of the boys and girls in that class were equal.

Based on the question mentioned conditions and above stated assumptions, we are required to calculate the number of boys who like each sport separately.

Here, given that, "for every four girls that like basketball, one liked kickball", i.e.,

The ratio of the number of girls who liked basketball to that of kickball is (4 : 1).

Now, let us assume that the total number of girls in that class is "x"

Therefore, as per the condition that, "36 girls said they liked basketball",

we can write [{(4/5) * x} = 36]

Or, [x = {36 * (5/4)}]

Or, [x = (9 * 5)]

Or, (x = 45)

That is, the total number of girls in that class is 45.

And as per our assumptions, the total number of boys in that class is also 45.

Also given in the question statement that, "for every three boys who stated they like basketball, two boys liked kickball", i.e.,

The ratio of the number of boys who liked basketball to that of kickball is (3 : 2).

Therefore, number of boys who like basketball = (3/5) * 45] = (3 * 9) = 27.

And the number of boys who like kickball = (45 - 27)  = 18.

An object is moving at a speed of 3 kilometers every 5 days. Express this speed in yards per hour.

Answers

An object is moving at a speed of 27.3 yards per hour.

How to find the speed in yards?

3 kilometers must first be converted to yards.

1 m =  1.09 yards.

1 Km = 1093.61

3 km to yards is  3280.84  

Currently, we must convert 5 days to hours. There are 24 hours every day, we shall multiply that number by 5 to find the number of hours in 5 days.

5 * 24 = 120 hours

To determine the speed in yards per hour, divide 3280.84 by 120.

3208.4/120
