(x +8)(x + 11) = 0
Pls help I’m dumb and don’t know this ...

Answer:

x = 11

Step-by-step explanation:

23 = 3x-10

1. Add 10 to both sides of the equation. -10 plus 10 is equal to zero so it cancels out to nothing, and 23 plus 10 is 33.

2. The new equation is now 33 = 3x.

3. Now you want to divide both sides by 3 to make x by itself since that is what you are trying to solve for.

4. 33/3 is equal to 11 so x = 11.

The value of the unknown number is 11

Inequality is a concept in mathematics that shows the comparison between two non-equal numbers.

From the given information

∴

3x - 10 = 23

Collect like terms

3x  = 23 + 10

3x = 33

Divide both sides by 3

[tex]\mathbf{\dfrac{3x}{3}= \dfrac{33}{3}}[/tex]

x = 11

Answer:

  2

Step-by-step explanation:

In general, if the given angle is opposite the shorter of the two given sides, there will be 0 or 2 possible triangles. The attachments show the two possibilities.

__

There will be zero possible triangles if the ratio of sides is less than the sine of the angle. Here, 24/29 ≈ 0.8276, sin(43°) ≈ 0.6820. The ratio of sides is greater, so there are two possible triangles.

If the given angle is opposite the longer of the two given sides, there is one possible triangle. The same is true if the given angle is between the two given sides.

Answer:

a)[tex]s=\sqrt{1+d^2}[/tex]

b)d(t)=500t

c)[tex]s(t) =\sqrt{1+250000t^2}[/tex]

Step-by-step explanation:

d = Horizontal distance

s = the distance between the plane and the radar station

The horizontal distance (d), the one mile altitude, and s form a right triangle.

So, use Pythagoras theorem

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]s^2=1^2+d^2[/tex]

a) [tex]s=\sqrt{1+d^2}[/tex]

(b) Express d as a function of the time t (in hours) that the plane has flown.

[tex]distance = speed \times time[/tex]

d(t)=500t

(c) Use composition to express s as a function of t.

[tex]s(t) =\sqrt{1+d^2}[/tex]

using b

[tex]s(t) =\sqrt{1+(500t)^2}\\s(t) =\sqrt{1+250000t^2}[/tex]

Complete Question

The complete question is shown on the first uploaded image

Answer:

a

 [tex]g(h(x)) = \sqrt[4]{x^2 + x +5} + 3[/tex]

b

 [tex]h(g(x))  = \sqrt{x}  + 7\sqrt[4]{x} + 17[/tex]

c

 [tex]h(h(x)) =  [x^2 + x + 5 ]^2 + x^2 + x + 10[/tex]

Step-by-step explanation:

From the question we are told that

    [tex]h(x) =  x^2  + x  + 5[/tex]

and  

    [tex]g(x) = \sqrt[4]{x} + 3[/tex]

Considering first question

Now we are told  g(h(x))

i.e

        [tex]g(h(x)) =  [x^2 + x + 5 ]^{\frac{1}{4} } + 3[/tex]

=>     [tex]g(h(x)) = \sqrt[4]{x^2 + x +5} + 3[/tex]

Considering second  question

   Now we are told  h(g(x))

i.e

    [tex]h(g(x)) =  [x^{\frac{1}{4} } + 3]^2 +  x^{\frac{1}{4} } + 3 + 5[/tex]

=> [tex]h(g(x)) =  x^{\frac{1}{2} } + 6x^{\frac{1}{4} } + 9+ x^{\frac{1}{4}}  + 8[/tex]

=>  [tex]h(g(x))  = x^{\frac{1}{2}} + 7x^{\frac{1}{4}} + 17[/tex]

=>  [tex]h(g(x))  = \sqrt{x}  + 7\sqrt[4]{x} + 17[/tex]

Considering third question

         [tex]h(h(x))= [x^2 + x + 5]^2 + [x^2 + x + 5 ] +  5[/tex]

=>       [tex]h(h(x)) =  [x^2 + x + 5 ]^2 + x^2 + x + 10[/tex]

Answer:

remainder = 8

answer is: 2a^(2) + 2a + 5 remainder 8

Step-by-step explanation:

Answer:

sinФ = 8/17

cosФ = 15/17

tan Ф = 8/15

csc Ф = 17/8

sec Ф = 17/15

cot Ф = 15/8

Step-by-step explanation:

Let us revise the trigonometry functions

In the given figure

The opposite side to angle Ф = 8

The adjacent side to angle Ф = 15

Find the hypotenuse using Pythagoras' theorem

[tex]Hypotenuse = \sqrt{8^{2}+15^{2} }[/tex]

[tex]Hypotenuse = \sqrt{64+225}[/tex]

[tex]Hypotenuse = \sqrt{289}[/tex]

[tex]Hypotenuse = 17[/tex]

Let us use the rules above to find the trigonometry functions

sinФ = 8/17

cosФ = 15/17

tan Ф = 8/15

csc Ф = 17/8

sec Ф = 17/15

cot Ф = 15/8

Answer:

Step-by-step explanation:

Slope intercept form is y = mx + b

First find the slope or m with this equation [tex]\frac{y2 - y1}{x2 - x1}[/tex] (plug in) [tex]\frac{6 - 2}{12 + 4}[/tex] = [tex]\frac{4}{16}[/tex]=  [tex]\frac{1}{4}[/tex]

So your slope is [tex]\frac{1}{4}[/tex]

To find the y-intercept you use y= mx + b and plug in.

6 = 1/4(12) + b

6 = 3 + b (minus 3 on both sides)

3 = b

so 3 is the y-intercept

So the answer is A.

Answer:

2) D. 62

Step-by-step explanation:

Find the complete question in the attached diagram.

Range is the difference between the highest score and the lowest score.

Given the following scores on the Overcontrolled-Hostility scale.

69, 84, 56, 89, 47, 63, 86, 58, 74, 35, 71, 60

From the data:

Highest score =  89

Lowest score = 35

Range = Highest score - Lowest score

Range = 89-35

Range = 54

Hence the possible value of the range is 54

For the scores on the Defensiveness scale given as:

38, 70, 35, 42, 26, 87, 74, 61, 69, 46, 63, 25

Highest score = 87

Lowest score = 25

Range = Highest score - Lowest score

Range = 87-25

Range = 62

Hence the possible value of the range is 62

Answer:When you change the position and speed of the ball in the carnival

game, you transfer energy to the ball. Energy is the ability of a person

or an object to do work or to cause a change. When you do work on an

object, some of your energy is transferred to the object. You can think

of work as the transfer of energy. In fact, both work and energy are

measured in the same unit, the joule.

The man in the photograph above converts one form of energy

into another form when he uses his muscles to toss the ball. You can

think of the man and the ball as a system, or a group of objects that

affect one another. Energy can be transferred from the man to the

ball, but the total amount of energy in the system does not change

Answer: 2.2 meters

Step-by-step explanation:

The data is:

The initial piece is 6.35 meters long.

We cut 25 pieces of 16.2cm each, so in pieces only we have:

25*16.2cm = 405cm

1m = 100cm

Then: 405cm = (405/100) m = 4.05m

And each time that we cut a piece, we have 4mm of waste.

Then we have 25 times the 4mm of waste, this means that the total waste is:

4mm*25 = 100mm

and 1000mm = 1m

100mm = (100/1000) m = 0.1m

So the total amount that was cut is:

4.05m + 0.1m = 4.15m

The length in the channel iron will be: 6.35m - 4.15m = 2.2 meters

Answer:

Step-by-step explanation:

the volume of a prism is always the base times the height this can be written as V = bh

we know the volume is 144 and the base is 24

substitute this into your equation: 144 = 24h

divide both sides by 24 to find h

144 ÷ 24 = 6

so you get h = 6

Assuming an oblique prism has a volume of 144 cubic units. The perpendicular height of the prism is 6 units.

Using this formula

Volume of prism=Base area ×Height

Hence:

144=24×h

h=144/24

h=6 units

Therefore, assuming an oblique prism has a volume of 144 cubic units. The perpendicular height of the prism is 6 units.

Answer:

  b)  12.2 ft

Step-by-step explanation:

Based on the attached and the answer choices, it looks like we're to assume the pole is leaning away from the sun. Of course, we must assume the angle the pole makes with the ground and the angle of elevation are in the same plane.

The problem can be solved using the law of sines. In the attached, we have ...

  AD/sin(O) = OA/sin(D)

The angle at D is 180° -45° -75° = 60°, so this can be written as ...

  AD = sin(45°)(15 ft)/sin(60°)

  AD ≈ 12.247 ft

The pole is about 12.2 feet long.
