PLSS HELP With 1 3 And 4

Answers

Answer 1

Answer:

1.) slope is 6

2.) slope is -4

4.)slope is undefined

Step-by-step explanation:

1.) For one we can use the equation y2-y1/ x2-x1

First, pick any 2 points that you want to use to plug into the equation

(0, -3) and (1, 3)

Next, plug in and solve!

3-(-3)/ 1-0= 6

The slope is 6

2.) We can use this same equation for the problem and plug in!

(-1, 5) (2,-7)

-7- 5/ 2-(-1)= -4

The slope is -4!

4.) Use the same equation and find the slope!

(8, 1) and (8, 2)

2-1/ 8-8= undefined

Because we cannot divide by a 0 the slope is undefined!

What is a line segment?

A line section that can connect two places is referred to as a segment.

Lines are very useful and common in geometry we daily use them.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

In other words, the line is a straight figure which has zero width and infinite length but if we take a segment then it is called a line segment which will be finite.

Given in the image 3 lines are parallel and intersect two lines that are randomly inclined.

Let's say the missing length is x

By geometrical similarity rule

x/32 = 35/20

x = 32 × 35/20

x = 56 hence 56 will be the missing side length of the given figure.

Determine whether the ordered pair (0, 2) is a solution to the equation -2x + y = -1
O No, (0, 2) is not a solution.
O Yes, (0, 2) is a solution

Answers

Answer:

O Yes, (0, 2) is a solution

Step-by-step explanation:

The Solution of an Equation

Given the equation

-2x + y = -1

An ordered pair (a,b) is a solution of the equation if

-2a + b = -1

Let's test the point (0,2) to check if it's a solution of the equation:

Replacing x=0, y=-1

-2(0) + (-1) = -1

0 - 1 = -1

-1 = -1

Since the equation is satisfied, the pair (0,2) is a solution.

Answer: O Yes, (0, 2) is a solution

During the summer months, science center tickets are 3 for $36.75 and zoo tickets are 4 for $51.How much will a group of 12 students save by choosing the science center?

Answers

Answer: They will save $6

Step-by-step explanation:

Science Center

There are 12 students and tickets are 3 for $36.75. There are 4 groups of 3 students, so we can find the price for the science center by multiplication:

4 x 36.75 = 147

Zoo

There are 12 students and tickets are 4 for $51. There are 3 groups of 4 students, so we can find the price for the zoo by multiplying, too:

3 x 51 = 153

To find out how much a group of 12 will save by choosing the science center we subtract

153 - 147 = 6

They will save $6

What are a range and domain?

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x).

A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Given function  [tex]e^x[/tex] when we plot the graph of the function it is observed that all the graph of the function varies in the positive part of y. The ranges of the function lie at y > 0 and the domain will be all the real numbers.

Therefore the domain and the range of the function F(x) = [tex]e^x[/tex] will be domain is all real numbers and the range is y > 0. The correct option is C.

(picture included with ONE question ^^^^^) only part a

Answers

Answer:

A. y = 1.5m + 7

B. at 7 months the baby will weigh 17.5 pounds

C. Since the baby is born weighing 7 pounds, at 0 months he will weigh 7 pounds. This tells us that the y-intercept will be seven. And since the baby is gaining 1.5 pounds every month, this means that the slope will be 1.5 and m will be the x of our y = mx + b equation. For part B, we simply plug in 7 to m and solve by multiplying 1.5 and 7 to get 10.5, then adding 7 to get 17.5.

Describe how
factoring can help you find the x-intercepts
of the graph of the quadratic function
y=x2 - 4x + 3.

Answers

See attachment for answer and explanation:

The x-intercepts of the graph of the quadratic function is 1, 3.

What are quadratic equations?

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0

Now the quadratic function is,

y = x² - 4x + 3

Now for x-intercepts, y = 0.

⇒ x² - 4x + 3 = 0

Factoring we get,

⇒ x² - 3x - x + 3 = 0

⇒ x(x - 3) - 1(x - 1) = 0

⇒ (x - 1) (x - 3) = 0

Thus we get,

x = 1, 3

this is the required x-intercepts of the graph of the quadratic function.

Thus, the x-intercepts of the graph of the quadratic function is 1, 3.

Step-by-step explanation:

The lateral surface area is the product of half the circumference, and the slant height:

  LA = πrh = π(11.4 cm)(23 cm) = 262.2π cm²

The total surface area adds the area of the base to that:

A truck that is 11 feet tall and 7 feet wide is traveling under an arch. The arch can be modeled by:

a) Will the truck fit under the arch? Explain (with numerical details).

BIRD



b) What is the maximum width that a truck 11 feet tall can have and still make it under the arch?

Answers

Answer:

Yes

8 ft

Step-by-step explanation:

The equation of the arch is

[tex]y=-0.0625x^2+1.25x+5.75[/tex]

Differentiating with respect to [tex]x[/tex] we get

[tex]\dfrac{dy}{dx}=-2\times 0.0625x+1.25=-0.125x+1.25[/tex]

Equating with zero

[tex]0=-0.125x+1.25\\\Rightarrow x=\dfrac{-1.25}{-0.125}\\\Rightarrow x=10[/tex]

Double derivative of the equation

[tex]\dfrac{d^2y}{dx^2}=-0.125<0[/tex]

So, the function is maximum at [tex]x=10[/tex]

[tex]y=-0.0625x^2+1.25x+5.75=-0.0625\times 10^2+1.25\times 10+5.75\\\Rightarrow y=12[/tex]

The function is maximum at [tex](10,12)[/tex]

So, the truck's center should be below the point [tex](10,12)[/tex] for maximum width to pass through.

Now truck is 11 feet tall so [tex]y=11[/tex]

[tex]11=-0.0625x^2+1.25x+5.75\\\Rightarrow -0.0625x^2+1.25x-5.25=0\\\Rightarrow x=\frac{-1.25\pm \sqrt{1.25^2-4\left(-0.0625\right)\left(-5.25\right)}}{2\left(-0.0625\right)}\\\Rightarrow x=6,14[/tex]

The maximum width of the truck can be [tex]14-6=8\ \text{ft}[/tex] if it is 11 feet tall.

So, the truck which has a width of 7 feet can fit under the arch.
