Answer:

B. Obtuse angle

Step-by-step explanation:

Remember that a right angle is 90 degrees and would be like the edge of a square or rectangle going completely vertical. An obtuse angle is larger than 90 degrees so the vertex or point where both lines connect would have both lines farther apart. An acute angle is smaller than a 90-degree angle and is closer to touching the lines (a tip for remembering acute angles could be "a-cute angle" or a smaller cute angle). Hope this helps!

Answer:

[tex] 3 - a [/tex]

Step-by-step explanation:

Given that when you add two numbers together the result is 3.

The greater of the number is given as a.

Let "x" represent that lesser number.

Thus:

[tex] a + x = 3 [/tex]

To make x the subject of the formula. Subtract a from both x.

[tex] a + x - a = 3 - a [/tex]

[tex] x = 3 - a [/tex]

Therefore, the expression that represents the lesser number, x, is:

[tex] 3 - a [/tex]

Answer:

[tex]Distance = 39.2[/tex]

Step-by-step explanation:

Given

[tex]Distance = 6ft;\\ Time = 15seconds[/tex]

Required

Determine the distance covered in 98 seconds

To solve this, the following assumption must be made:

So, first we calculate the speed

[tex]Speed = \frac{Distance}{Time}[/tex]

Substitute 6 for Distance and 15 for Time

[tex]Speed = \frac{6}{15}[/tex]

[tex]Speed = 0.40[/tex]

Next, is to calculate the required distance

[tex]Speed = \frac{Distance}{Time}[/tex]

In this case:

[tex]Speed = 0.40[/tex] because it is constant and

[tex]Time = 98[/tex]

The expression becomes:

[tex]0.40 = \frac{Distance}{98}[/tex]

Make Distance the subject:

[tex]Distance = 0.40 * 98[/tex]

[tex]Distance = 39.2[/tex]

The peacock will walk 39.2 feet in 98 seconds

Answer:

The value is  [tex]0.152 \le \frac{\sigma_1^2}{\sigma_2^2} \le 1.835[/tex]

Step-by-step explanation:

From the question we are told that

  The number of observation for X  is [tex]n_1 = 8[/tex]

  The sample mean for X  is  [tex]\= x _1 = 15.7 5[/tex]

  The sample variance for X is [tex]s^2_1 = 46.21[/tex]

   The number of observation for Y  is [tex]n_1 = 10[/tex]

  The sample mean for Y  is  [tex]\= x _1 = 23.3[/tex]

  The sample variance for Y is [tex]s^2_1 = 92.8[/tex]

Generally the degree of freedom for X is      

     [tex]df_1 = n_1 - 1[/tex]

=>  [tex]df_1 = 8 - 1[/tex]

=>  [tex]df_1 = 7[/tex]

Generally the degree of freedom for X is      

     [tex]df_2 = n_2 - 1[/tex]

=>  [tex]df_2 = 10 - 1[/tex]

=>  [tex]df_2 = 9[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

=>  [tex]\frac{\alpha}{2} = \frac{0.10}{2}[/tex]

=>  [tex]\frac{\alpha}{2} = 0.05 }[/tex]

Generally the 90% confidence interval for the ratio of variances is mathematically represented as

     [tex]\frac{s_1^2}{s_2^2 } * \frac{1}{F_{ 1 - \frac{\alpha }{2} , df_1 , df_2 }} \le \frac{\sigma_1^2}{\sigma_2^2} \le \frac{s_1^2}{s_2^2 } * \frac{1}{F_{ \frac{\alpha }{2} , df_1 , df_2 }}[/tex]

=>  [tex]\frac{46.21}{92.68 } * \frac{1}{F_{ 1 - 0.05 , 7 , 9 }} \le \frac{\sigma_1^2}{\sigma_2^2} \le \frac{46.21}{92.68 } * \frac{1}{F_{ 0.05 , 7 , 9 }}[/tex]

=>  [tex]\frac{46.21}{92.68 } * 0.304 \le \frac{\sigma_1^2}{\sigma_2^2} \le \frac{46.21}{92.68 } * 3.677[/tex]

=>  [tex]0.152 \le \frac{\sigma_1^2}{\sigma_2^2} \le 1.835[/tex]

Answer:

To find the quotient of 3 divided by 1/6 you must multiply by the reciprocal of the fraction, in this case it is 6.

So you would rewrite it as,

3*6=18

So your answer is multiply 3 by 6.

Answer:

y = 75 - x

Step-by-step explanation:

From the question, we are given variables, and then we can see that

when x = 75 then y = 0

when x = 30 then y = 45

Finding the difference, we have

slope(m) = (45 - 0) / (30 - 75)

slope(m) = 45 / -45

slope(m) = -1

Next, we use the calculated m, to find b, using the formula

y = mx + b

0 = -1 * 75 + b

0 = -75 + b

b = 75

And finally, to get the needed equation, we say that

so y = mX+c

So that

y = -1 * x + 75

y = -x + 75

or y = 75 - x

Answer:

I think you have to do ( 3,450 x .05 ) x 18

Sorry if i'm wrong.

Balance at end is $6,555

Amount deposit in bank = $3,450

Rate = 5% = 0.05

Number of year = 18 year

Balance at end

Balance at end = PRT + Amount deposit in bank

Balance at end = (3,450)(0.05)(18) + 3,450

Balance at end = 3,105 + 3,450

Answer:

9 Hours

Step-by-step explanation:

If it is increased by 5 km that would make it 50. But, let's go back to the 45 to find out how many km we are traveling. If we are doing 45 km per hour then you just multiply the 10 by 45 and get 450 km. Now that we have that, if the new speed is 50 km per hour, all we need to do is 450 divided by 50, which will get you 9.

The solution is Option A.

The value of the equation is P = -2 - 2i

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as z

Now , the value of z is

z = ( 1 - i )

Now , calculate the value of z³ is

z³ = ( 1 - i )³

z³ = 1³ - i³ - 3 ( 1 )²i + 3 ( i )² 1

On simplifying the equation , we get

z³ = 1 + i - 3 - 3i

z³ = -2 - 2i

Therefore , the value of z³ is -2 - 2i

The point on the graph is A

Hence , the value of the equation is -2 - 2i
