According to the Venn diagram below, what is (image below)

A. 3/25
B. 4/25
C. 2/25
D. 1/25

Answer:

Part A) Option C. obtuse

Part B) Option B. acute

Step-by-step explanation:

we know that

Applying the Pythagoras Theorem

if [tex]c^{2}=a^{2}+b^{2}[/tex] ----> is a right triangle

if [tex]c^{2}>a^{2}+b^{2}[/tex] ----> is an obtuse triangle

if [tex]c^{2}<a^{2}+b^{2}[/tex] ----> is an acute triangle  

where

c is the greater side

Part A) A triangle has side lengths 32, 45 and 18. What type of triangle is it?

we have

[tex]c^{2}=45^{2}=2,025[/tex]

[tex]a^{2}+b^{2}=32^{2}+18^{2}=1,348[/tex]

therefore

[tex]c^{2}>a^{2}+b^{2}[/tex]

Is an obtuse triangle

Part B) A triangle has side lengths 44, 36 and 30. What type of triangle is it?

we have

[tex]c^{2}=44^{2}=1,936[/tex]

[tex]a^{2}+b^{2}=36^{2}+30^{2}=2,196[/tex]

therefore

[tex]c^{2}< a^{2}+b^{2}[/tex]

Is an acute triangle

Answer:

x = 88.2

Step-by-step explanation:

The angle at the top of the triangle = 90° - 10° = 80°

and the left side of the triangle is x ( opposite sides of a rectangle )

Using the tangent ratio in the right triangle

tan80° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{500}{x}[/tex]

Multiply both sides by x

x × tan80° = 500 ( divide both sides by tan80° )

x = [tex]\frac{500}{tan80}[/tex] ≈ 88.2

Answer:

See explanation

Step-by-step explanation:

Zeroe of the function is such velue of x at which f(x)=0.

1. Consider the function [tex]f(x)=-x(3x-2)^2 (x+9)^5.[/tex]  

Zeros are:

[tex]-x(3x-2)^2(x+9)^5=0\\ \\x=0\text{ or }x=\dfrac{2}{3}\text{ or }x=-9.[/tex]

Zero [tex]x=0[/tex] has multiplicity of 1, zero [tex]x=\dfrac{2}{3}[/tex] has multiplicity of 2, zero [tex]x=-9[/tex] has multiplicity of 5.

At [tex]x=0[/tex] or [tex]x=-9[/tex] the graph of the function crosses the x-axis, at [tex]x=\dfrac{2}{3}[/tex] the graph of the function touches the x-axis.

2. Consider the function [tex]f(x)=x^3+10x^2+25x=x(x^2+10x+25)=x(x+5)^2.[/tex]  

Zeros are:

[tex]x(x+5)^2=0\\ \\x=0\text{ or }x=-5.[/tex]

Zero [tex]x=0[/tex] has multiplicity of 1, zero [tex]x=-5[/tex] has multiplicity of 2.

At [tex]x=0[/tex] the graph of the function crosses the x-axis, at [tex]x=-5[/tex] the graph of the function touches the x-axis.

Answer:

C

Step-by-step explanation:

Since we are dealing with recursive equations, we can use a simple format.

[tex]a_{1}=x \\ \\ a_{n}=a_{n-1}+y[/tex]

x is the starting value and y is the change.

We can see that the change is -5.6 since 5.6 is being subtracted from each term each time.

So the equation would be

[tex]a_n=a_{n-1}-5.6[/tex]

We can check this by plugging in the numbers.

Let's see if -8.3 works, which is the 2nd term in the equation.

[tex]a_2=a_{2-1}-5.6 \\ \\ -8.3=a_{1}-5.6 \\ \\ -8.3=-2.7-5.6 \\ \\ -8.3=-8.3[/tex]

Therefore, the recursive rule is the third one.

Answer:

The final temperature of the solution was 5°C

Step-by-step explanation:

we know that

1) At the start of an experiment, the temperature of a solution was -12°C

In this moment the temperature is -12°C

2) During the experiment, the temperature of the solution rose 5°C each hour during 4 hours

so

5°C*4=20°C

In this moment the temperature is -12°C+20°C=8°C

3) The temperature changed by -3°C

In this moment the temperature is 8°C-3°C=5°C

Answer:

The final temperature of the solution was 5°C

Answer:

34.

Step-by-step explanation:

Answer: 4.59

sin(35)=x/8

8*sin(35)=x

x=4.59

The value of x in the given triangle round to the nearest hundredths is:

                           4.59

From the given triangle we observe that the side x is the opposite side corresponding to angle 35°.

i.e. we will use sine trignometric ratio in the triangle to get the value of x.

We know that:

[tex]\sin 35=\dfrac{x}{8}ddd[/tex]

Since the sine of an angle is the ratio of opposite side to the hypotenuse of the right angled triangle.

i.e.

[tex]x=8\times \sin 35\\\\i.e.\\\\x=8\times 0.5736\\\\i.e.\\\\x=4.588[/tex]

which is approximately equal to 4.59  units.

Answer:

(n - 43)³

Step-by-step explanation:

Let the number be n.

Then the desired expression is (n - 43)³

Answer:

Algebraic expression = (x-43)^3

Step-by-step explanation:

Given , the verbal expression is the cube of the difference of a number and 43.

Let x be the number

Now, according to question

Difference means subtraction  in which a number is subtracted from the other number

Difference of a number and 43

It means 43 is subtracted from x

Now , the algebraic  expression =x-43

Cube of the difference of a number x and 43 =(x-43)(x-43)(x-43)

Cube of a number means multiply a number three times with self .

Therefore, Cube of the difference of a number x and 43=[tex](x-43)\times (x-43)\times(x-43)[/tex]

 Cube of the difference  of a number x and 43=(x-43)^3

Because in multiply  when base same then power of the number added.

Answer:

The center is at [tex](2,4)[/tex]

3 units

Step-by-step explanation:

You can observe in the graph a circle.

The x-coordinate and the y-coordinate of the center of the circle shown in the figure are:

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

Therefore, the point of the center of the circle is:

[tex](2,4)[/tex]

 You can observe that the diameter goes from -1 to 5, then the diameter is:

[tex]diameter=1units+5units\\\\diameter=6units[/tex]

The radius is half the diameter. Therefore, you can say that the radius of this circle is:

[tex]radius=\frac{diameter}{2}\\\\radius=\frac{6units}{2}\\\\radius=3units[/tex]

ANSWER

The center is (2,4)

The radius is 2√2 units

EXPLANATION

Each of the ticks is 1 unit

Counting two ticks from the origin to the right and 4 units up will land us at the center of the circle.

Hence the center is (2,4)

The circle passes through (0,2).

The radius is

[tex]r = \sqrt{ {(2 - 0)}^{2} + {(4 - 2)}^{2} } [/tex]

[tex]r = \sqrt{8} = 2 \sqrt{2} [/tex]

I’m not quite sure what the function is but if it’s sine the period is pi/8

ANSWER

The period is

[tex] \frac{\pi}{8} [/tex]

EXPLANATION

The given function completes four cycles on the interval

[tex]

[ - \frac{\pi}{4} , \frac{\pi}{4} ][/tex]

Therefore the period is

[tex] = \frac{ \frac{\pi}{4} - \frac{\pi}{4} }{4} [/tex]

Simplify the numerator:

[tex] = \frac{ \frac{\pi}{2}}{4} [/tex]

Simplify further to get:

[tex]= \frac{\pi}{8} [/tex]

Answer:

  124°

Step-by-step explanation:

Supplementary angles add to 180°.

  56° + second angle = 180°

Subtract 56° from both sides of the equation:

  second angle = 180° - 56° = 124°

Answer:

(1 , 1)

Step-by-step explanation:

Given in the question two equations

Equation 1

y = x² – x + 1

Equation 2

y = x

Equate both equations

x² – x + 1 = x

0 = x² – x + 1 - x

x² – 2x + 1 = 0

x² - x - x + 1 = 0

x(x - 1) -1(x - 1) = 0

(x - 1)(x - 1) = 0

(x-1)² = 0

x - 1 = 0

x = 1

Plug x = 1 in first equation

y = 1² – 1 + 1

y = 1

Answer:

The answer is option A, or (1,1)

Step-by-step explanation:

I just took the test

There were 3 different fish caught, Salmon, Herring and Flounder.

4/9 were Herring, 2/9 were Salmon, 4/9 +2/9 = 6/9

This means 3/9 were Flounders ( 3/9 + 6/9 = 9/9 = 1)

3/9 can be reduced to 1/3.

1/3 of the fish were Flounders.

Divide the amount of flounders by the portion caught:

12 / 1/3 = 12 * 3/1 = 36 total fish.

Now you have total number of fish, multiply the total by each portion for each type of fish.

Total fish = 36

Herring = 4/9 x 36 = 16

Salmon = 2/9 x 36 = 8

Simple Method: Rise (go up) over Run (go left or right)

Start from a perfect point then rise and run.

Rise: 3, Run: 3 = 3/3 = 1

Alternatively, you could pick two points and use the formula y2 - y1/x2 - x1

Just as an example, I will choose (-2, -3) and (2, 1)

plug in:

1 + 3/2 + 2 = 4/4 = 1

ANSWER

1

EXPLANATION

The slope of the given line is obtained using the formula:

[tex]m = \frac{rise}{run} [/tex]

From the diagram the rise is 2 units and the run is 2 units.

This implies that,

[tex]m = \frac{2}{2} = 1[/tex]

Hence the slope of the given line is 1.

Area of circle

= 90/360 x π x (10)^2

= 1/4 π x 100

= 25 π meter^2

Final answer:

The area of a sector with a central angle of 90° and a radius of 10 meters is calculated using the formula A = θ/360 × πr². Substituting the given values, the area is found to be 25π m². The correct answer is D. 25π meters².

Explanation:

Finding the Area of a Sector

To find the area of a sector with a central angle of 90° in a circle with a radius of 10 meters, we use the formula for the area of a sector, which is A = θ/360 × πr², where θ is the central angle in degrees, π is the mathematical constant approximately equal to 3.14159, and r is the radius. Since the central angle θ is 90°, and the radius r is 10 meters, we have:

A = 90°/360° × π × (10 m)²
= 0.25 × π × 100 m²
= 25π m².

Therefore, the correct answer is D. 25π meters².
