Answers

Answer 1

Answer:

y = 2/3x +6 for x< -3

y = 2/3x +1 for x> 3

Step-by-step explanation:

The graph is a line for x < -3

( - 6,2) and ( -3,4)

The slope is m= ( y2-y1)/(x2-x1)

m = ( 4-2)/(-3 - -6) = 2/ ( -3+6) = 2/3

The slope is 2/3

Using point slope form

y-y1 = m(x-x1) and the point ( -6,2)

y -2 = 2/3(x - -6)

y -2 = 2/3(x +6)

y-2 = 2/3 x +4

y = 2/3x +6 x< -3

The graph is a line for x > 3

(3,3) and ( 6,5)

The slope is m= ( y2-y1)/(x2-x1)

m = ( 5-3)/(6-3) = 2/ (3) = 2/3

The slope is 2/3

Using point slope form

y-y1 = m(x-x1) and the point (6,5)

y -5 = 2/3(x - 6)

y-5 = 2/3 x -4

y = 2/3x +1 x> 3

A family is planning a camping trip at a state park. The state park has 9 campgrounds, each with 6 campsites. The family wants to go on a hike, and the park has 4 hiking trails. The children also want to go for a swim at one of the 4 beaches. How many different ways can the family plan a camping trip?

Answers

Answer:

Step-by-step explanation:

Camping trip different ways = No of campgrounds x campsites each campground

9 x 6 = 54

Hiking trip different ways = 4 (hiking trails)

Swimming different options = 4 (beaches)

Total ways of planning trip = 54 + 4 + 4 = 62

The function f has the property that as x gets closer and closer to 4, the values of f(x) get closer and closer to 7. Which of the following statements must be true?

Answers

Answer:

Step-by-step explanation:

x going to 4 is given by limx->4 and closer to 7 is given by =7

The correct statement is [tex]\lim_{x \to 4} f(x)[/tex] = 7.

What is function?

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given statement:

x gets closer and closer to 4, the values of f(x) get closer and closer to 7.

So, x gets closer and closer to 4 shows

x-> 4

and, f(x) get closer and closer to 7 shows

f(x)=7

Combining both we can write using the limit function x gets closer and closer to 4 require limit

[tex]\lim_{x \to 4} f(x)[/tex] = 7.

How do I write this equation? Pls help ASP

Answers

This is a question about angles and equations! Let's see how to solve this.

The angle [tex]\angle PQR[/tex] is the sum of the angles [tex]\angle MQR[/tex] and [tex]\angle PQM[/tex]. So, we can do a equation with this information and solve it:

[tex]\angle PQR = \angle MQR + \angle PQM\\\\138x -1 = 115 + 23x -1\\138x - 23x = 115 + 1 - 1\\115x = 115\\x=\frac{115}{115} \\x= 1[/tex]

what are the intersections between the lines y=x squared and 6x + 3y= 24?

Answers

Answer:

The intersection points between the functions are (-4,16) and (2,4)

Step-by-step explanation:

Intersection Between Functions

We are given the functions:

[tex]y=x^2[/tex]

[tex]6x+3y=24[/tex]

To find the intersections between them, we have to solve the system of equations. Let's start by simplifying the second equation by 3:

[tex]2x+y=8[/tex]

Now we substitute [tex]y=x^2[/tex] into this equation:

[tex]2x+x^2=8[/tex]

Solve the quadratic equation by any of the available methods.

Subtract 8:

[tex]2x+x^2-8=0[/tex]

Sort the polynomial:

[tex]x^2+2x-8=0[/tex]

Factor:

[tex](x+4)(x-2)=0[/tex]

Solve:

[tex]x=-4, x=2[/tex]

Now find the y-coordinate of each solution:

[tex]y=x^2=(-4)^2=16[/tex]

The point is (-4,16)

For x=2:

[tex]y=x^2=2^2=4[/tex]

The point is (2,4)

The intersection points between the functions are (-4,16) and (2,4)

When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.Read this sentence from the text:A sudden gust of wind or a sudden shower would put it out.How does this line develop the main idea of the essay?
