Answers

Answer 1

Answer:

At the positive integer value of x=7 the quadratic function begin to exceed the linear function

Step-by-step explanation:

we have

using a graphing tool

see the attached figure

For x < -1.405 and x > 6.405 the quadratic function begin to exceed the linear function

At the positive integer value of x=7 the quadratic function begin to exceed the linear function

Step-by-step explanation:

Answer 2

The positive difference between the maximums of functions g and f is 2

What is the positive difference between the maximums of functions g and f?

From the question, we have the following parameters that can be used in our computation:

f(x) = -x² + 4x + 6

So, the x of the vertex is

x = -4/2 * -1

x = 2

So, the maximum is

Max = -2² + 4(2) + 6

Max = 10

From the graoh, we have

Max = 12

So, we have

Difference = 12 - 10

Difference = 2

Hence, the positive difference is 2

Find ac. Round to the nearest tenth

Answers

Answer:

AC=6.37

Step-by-step explanation:

First you need to find m∠C

A triangle = 180 so you need to add 108 and 31

subtract 180-139

you get 41, so m∠C=41

Now we know all the angle measures.

Next we will use the law of sines

Go to google and type "law of sines calc"

google can usually provide with the formula and will even do the equation for you if you type in the numbers

So all you do is plug in the numbers and google will give you 6.37

0.75p=0.4+100

Answers

Answer:

p=133.866667

Step-by-step explanation:

Let's solve your equation step-by-step.

0.75p=0.4+100

Step 1: Simplify both sides of the equation.

0.75p=0.4+100

0.75p=(0.4+100)(Combine Like Terms)

0.75p=100.4

Step 2: Divide both sides by 0.75.

0.75p/0.75 = 100.4/0.75

p=133.866667

Find the total total surface area of the composite figure below with

r=2.2

l=10.2

h=8.7

Use 3.14 for LaTeX: \piπ.

Round to the nearest hundredth.

Pro tip: don't count the surfaces that are not exposed.

Answers

Given:

The radius of given fig = 2.2 unit

The height of the cylindrical part = 8.7 unit

The slant height of the cone = 10.2 unit

To find the total surface area of the given figure.

Formula

The given figure consists of a cylinder and a cone.

So, the surface area of the fig

[tex]SA = \pi r l+2\pi r h+\pi r^{2}[/tex]

Where, r be the radius

h be the height

l be the slant height

Now,

Putting,

r=2.2, h = 8.7, l=10.2 and π=3.14 we get,

[tex]SA = (3.14)(2.2)(10.2)+2(3.14)(2.2)(8.7)+(3.14)(2.2^{2} )[/tex] sq unit

or, [tex]SA = 70.4616+120.1992+15.1976[/tex] sq unit

or, [tex]SA = 205.8584[/tex] sq unit

or, [tex]SA = 205.86[/tex] sq unit

Hence,

The total surface area of the given figure is 205.86 sq unit.

How can you find 10% of any number without multiplying or dividing?

Answers

Answer:

subtract ---------

Step-by-step explanation:

To find value of the percentage of the number 10% of any number X without multiplying or dividing, divide X by 100 to get 1% and then multiply it by 10.

Let's say we want to find 10% of a number X. The key to this method lies in understanding that finding 10% of a number is the same as finding 1% of that number and then multiplying it by 10. To find 1% of X, we can divide X by 100, as 1% is equivalent to dividing by 100.

Step 1: Finding 1% of the number

1% of X = X / 100

Step 2: Finding 10% of the number

To get 10% of X, we multiply the 1% value by 10 since 10% is ten times greater than 1%.

10% of X = (X / 100) * 10

Now, let's demonstrate this method with an example:

Let's find 10% of 250.

Step 1: Finding 1% of 250

1% of 250 = 250 / 100 = 2.5

Step 2: Finding 10% of 250

10% of 250 = (2.5) * 10 = 25

So, 10% of 250 is 25.

#SPJ2

In ΔLMN, m∠L = 108°, m∠M = 25°, and ℓ = 12. What is m?

Answers

Answer:

m = 5.33

Step-by-step explanation:

First we need to calculate angle N.

Sum of angles in a triangle is 180°

∠L + ∠M + ∠N = 180°

108°+25°+∠N = 180°

∠N = 180°-(108°+25°}

∠N = 180°-133°

∠N = 47°

Given side l = 12, to get m, we will use the sine rule.

l/sinL = m/sinM = n/sinN

12/sin108° = m/sin25°

m × sin108°= 12sin25°

m = 12sin25/sin108°

m = 5.071/0.951

m = 5.33

Solve for x please ????

Answers

Answer:

Step-by-step explanation:

First, subtract 180 and "12x-3", which equals 180-12x+3

Then add 46, "5x+7", and "180-12x+3"

46+5x+7+180-12x+3 = 180

Since the degrees in a triangle add up to 180 degrees, cancel out the 180 degrees from this side "180-12x+3" and the other side "180"

46+5x+7-12x+3=0

46+10-7x=0

56=7x

and 17 are custard-filled. You randomly select one donut, eat it, and select another donut. Find the probability of selecting two custard-filled donuts in a row.
(Type an integer or a simplified fraction.)

Answers

Answer:

34/69

Step-by-step explanation:

2 are jelly-filled

5 are lemon-filled

17 are custard-filled

Total: 24

First drawing:

There are 24 donuts in total, 17 of which are custard filled.

p1(custard filled) = 17/24

Second drawing:

There are now a total of 23 donuts, 16 of which are custard filled.

p2(custard) = 16/23

The two drawings are independent events, so the overall probability is the product of the individual probabilities.

Overall probability of drawing two custard filled donuts:

p(2 custard filled) = p1 * p2 = 17/24 * 16/23 = 17/3 * 2/23 = 34/69
